Cleanliness refers to the amount of dust (including microorganisms) in the clean air

The air cleanliness of the clean room generally requires the following tests to draw conclusions:

l   Idle, static test

The clean room has been installed, the clean air conditioning system is in normal operation, and the indoor production equipment and operators are not in place.

Or the clean room purification air conditioning system is already in normal operation, the process equipment has been installed, and the test is carried out without production personnel in the room.

l   Run, dynamic test

The clean room has been tested under normal production conditions. The detection of air volume, wind speed, positive pressure, temperature, humidity, and noise in the clean room can be carried out in accordance with the relevant regulations of general use and air conditioning.

After installing and fixing the Ecolead automatic roller shutter filter of Nanjing Yixiou, the construction unit may have doubts when debugging. I am afraid that without the cooperation of our after-sales service engineers, the debugging will be uncertain or the final result will be unsatisfactory. Today we will briefly list a few important points for sharing and absorption by colleagues and customers .

1. Direction of wind in and out. The automatic winding filter automatically controls the difference between the inlet and outlet directions through the existence of the pressure difference control, that is, the positive pressure on the inlet side and the negative pressure on the outlet side. If the direction of the inlet and outlet sides is reversed during actual installation, then even the inlet and outlet sides If the actual pressure difference reaches or far exceeds the set value, the equipment will not operate. At this time, it is necessary to reverse the air pipes connected to the air inlet and outlet at the differential pressure switch. Therefore, when debugging, it is first necessary to determine whether the direction of the air inlet and outlet corresponding to the pressure difference switch air pipe is correct.

2. Automatic mode status. There are two modes of operation with automatic mode. You need to press a key to enter the automatic mode. If it is not in automatic mode, the automatic winding filter cannot work automatically. Nanjing Isio

3. Check the filter material. First of all, it is necessary to check whether the new filter material winding tube in the new filter material box and the bottom old filter material winding tube are in the card slot or whether they are fixed, otherwise, transmission failure will occur during operation, and even the parts will be damaged. Nanjing Yixio then checked whether the filter material was dirty, because it took a long time for the filter to be energized for debugging. During this process, the filter material was contaminated with a lot of dust. When the suction device is started, the pressure difference between the filter material and the filter material is different. The value far exceeds the set value, and forced start under such a large negative pressure will damage the automatic winding filter. At this time, the suction equipment should be stopped, the dirty filter material should be replaced in manual mode, and then the suction equipment should be turned on to continue debugging.

4. Determine whether the rotation direction of the motor is correct. Compared with single-phase motors, three-phase motors run smoothly and have lower noise. Therefore, auto-winding roller shutters mostly use three-phase motors, and three-phase motors have the problem of forward and reverse rotation, so they must be entered during debugging. The manual mode runs briefly to determine the direction of the motor. Right turn from the left to see is counterclockwise operation. Nanjing Isio

The above debugging methods and experience of the coiled air filter are hoped to help our valued customers, and be well aware of them during the debugging process.

We all know that dust and other impurities will affect the quality of electronic components and film products. In order to improve the yield of products, clean rooms appear.

However, in the 100-level clean room with the highest level, the junior high-efficiency filter in the ventilation system cannot completely filter out the dust, and the accumulation will add up to some demanding products. Therefore, we need to add clean sheds to the production lines or equipment of these products.

Nanjing Yixiou’s clean shed is to filter the air in the clean room through a high-efficiency filter again and send it to the production area. According to the cleanliness requirements of the workshop, the clean shed is divided into ten thousand, thousand, and hundred grades, with the lowest grade of ten thousand, the highest grade of hundred, and the most common one is grade thousand.

Because the top and four sides of the Nanjing clean shed (Nanjing Yixiou) are closed, the bottom of the side is left blank about 10cm high, and the FFU at the top continues to work downwards to supply air, which causes the air pressure in the clean shed to be greater than the outside air pressure. The dust will not enter the clean shed, and to a certain extent, reduce the dust and dust generated in the clean shed due to frequent entry and exit of personnel.

The ceiling of the clean room is usually higher, and the height of the FFU configured in the clean shed to the production equipment is much lower than the height of the air outlet on the ceiling to the production equipment. Obvious airflow can be felt, which can blow away the dust. The cleanliness of the local production area is greatly improved, and the product yield is naturally improved.

In addition, if you want to improve the cleanliness level of the existing clean shed, you can increase the top FFU specialized in Nanjing Yixiou; if you want to move the equipment in the clean shed or add equipment, move the Nanjing Yixiou clean shed or FFU. Yes, it is convenient and flexible.

Why set automatic shutter filter the sewage treatment plant blower inlet gallery to replace traditional Primary filter plate why municipal engineering Institute reserved in advance will be well within the roll filter in the corridor design drawings The installation location of the filter, many environmental protection, municipal engineering, water treatment construction units did not know the situation when they bought the winding filter for the first time. This article analyzes in depth for customers to understand:

The aerodynamic equipment of the sewage treatment plant -the air suspension centrifugal blower must be in trouble-free operation all year round. These fans are the core equipment for the normal operation of sewage plants. They need high-quality, long-life blowers, and the corresponding prices are relatively high. In the air, especially in the current ordinary atmospheric environment, pollution is serious and there are many dust particles. Under the long-term high-speed airflow of the blower, large particles of dust will cause the fan blades, impellers and other equipment components to rust, wear, and prone to long-term unprotected operation. Shortening the life of the fan, affecting production, and causing direct loss is the damage of the fan, and the indirect loss is the loss of control of the entire water treatment process, causing adverse social effects and huge economic losses.

Given the above analysis, in order to ensure fan trouble, no hidden operation, protection of the blower maximum operating environment, will inevitably have to install the early effect of the air filtering device in the air inlet corridor. Effect of the air filter will directly affect the wastewater treatment plant Normal operation . Then why choose a coiled air filter instead of a plate-type primary filter, the reasons are as follows;
1. The winding filter is equipped with a powerful PLC control system and high-quality transmission mechanism , which can run by itself for a long time without shutting down or manually replacing the filter material, minimizing the number of maintenance and downtime ;
2. The coiled air filter is most suitable for use with large-scale ventilation equipment, with low resistance and large ventilation , which can meet the ventilation requirements of large cross-sections.
3. The operation and maintenance workload of the winding filter is extremely small , which completely avoids the defect that the initial effect of the plate type must be replaced regularly, and the effective filtering area is extremely large, without any obstruction in the middle part;
4. The coiled filter has a frame structure with high structural strength and can be adapted to large negative pressure ventilation . The previous successful cases can meet the internal fan ventilation demand of 2000pa ;
5. Less maintenance costs, lower operating costs , and basically no labor costs ;
6. The large air volume can meet the oxygen content required by the aerobic organisms in the aeration tank , which more perfectly matches the special industry needs of the sewage treatment plant .

Below we briefly introduce the relevant knowledge of the clean shed, so that everyone has a better understanding of the relevant selection and design of the clean shed

1. Main frame: Mainly assembled by special 4040 and 4080 sand surface oxidized industrial aluminum profiles of Nanjing Yixiou Company

Advantages: stable, no rust, no dust

2. Enclosure on all sides:

Antistatic vertical curtain: 0.3, 0.5, 1.0, 1.5, 2.0mmT different thicknesses can be selected according to requirements, transparent or black.

Advantages: high transparency, clear grid, good flexibility, easy to wipe

PC, acrylic and other anti-static plates: according to requirements, you can choose different thicknesses and colors, domestic or imported anti-static materials.

Advantages: impact resistance, aging resistance, long service life

3. Top cover: 4mmT aluminum-plastic plate

4. Lighting: dedicated clean room purification lamps to meet the dual needs of illuminance and cleanliness

The fan filter unit: using FFU Nanjing Yi Xiou specialized production equipment, size: 575 * 250 * 1175, Material: galvanized steel, high efficiency filter: 1170 * 570 * 70, efficiency: [In Email protected]

Advantages: maintenance-free operation for more than 5 years, special air duct designed according to fluid mechanics, low noise and low vibration. The air volume can be adjusted in three speeds, and the fan quality is reliable

6. The function and size can be customized according to actual needs

Nanjing Yixiou Technology is a professional manufacturer of clean sheds and air showers in Nanjing. Local customers can complete on-site measurement, drawing design, and proposal quotation within 24 hours.

In the previous article, we compared the functional advantages and disadvantages of the automatic rolling curtain air filter and the plate-type primary filter, but there must be users who feel that the unit price of the winding filter is too high, and they are unwilling to design the automatic winding in their own ventilation filter system. The filter case.

1Comparison of initial investment cost: The initial investment of Nanjing Ecolead automatic roller shutter filter is relatively large, and it is necessary to purchase a complete set of equipment including automatic PLC control system and motor transmission parts, and the initial effect only needs to purchase the plate filter and the corresponding modularization. Fixed frame, the initial effect filter was put into the initial stage to win the wind filter

2 Comparison of operating costs: The automatic roller shutter filter only needs to replace the special filter cotton in the later stage. The price of a roll of cotton is generally less than 1,000 yuan, which can meet the needs of one year. However, the plate-type primary filter is discarded as a whole piece. The size of the cross-sectional area is different, and the price of a replacement will exceed 1,000 yuan, plus the cost of personnel maintenance. The winding filter is better than the primary filter with its low cost of replacing the filter cotton.

It can be concluded that although the unit price of the coiled filter is high, the initial investment cost is high, but as the user’s use time passes, generally after 2-3 years, the cost of the two will be the same, and the later coiled filter With its complete control system and low filter material replacement cost, it stands out in the primary filter family and completely wins.

As the two primary air purification stages, automatic rolling curtain air filter and plate-type primary filter, the two most commonly used filters for fresh air filtration, how to choose which place to use, and what are the advantages and disadvantages of both sides? Please see the following analysis:

1. Comparison of filtering area: The filtering area of Nanjing Yixiou standard automatic winding filter is the area of a layer of flat winding special filter cotton on its cross section, and the unit plane area is the same as the filtering area.

The filter material of the plate-type primary filter is folded in a V shape. The unit’s flat cross-sectional area, the actual filter area of the filter material is close to twice, which greatly increases the ventilation and dust holding capacity, and extends the service life

In order to make up for this shortcoming of the coiled filter, Nanjing Ecolead developed a V-shaped roller blind filter. The cross-sectional area is fixed and the ventilation rate is too high. The air volume of the standard coiled filter cannot meet the requirements. In the case, use V-shaped winding filter to make up for the defect of fixed filter area and meet the requirements of use

2. Comparison of filter replacement: The automatic winding filter, as the name implies, is to automatically replace the filter material, without human operation to replace the filter material. The intelligent filter material replacement system is suitable for air conditioning units, metallurgical coal, sewage treatment plants, etc. An environment where the quantity is high and the filter material needs to be replaced frequently. Filter cotton can generally be used 5-10 times depending on the height of the filter, that is, basically one year, you don’t need to enter the primary filter system for any operation. The replacement of the filter material after all the filter materials are exhausted is also quite simple, and the operation is very convenient. We once timed the entire process of replacing the filter material at a time, about 3 minutes, which is equivalent to the initial effect time of replacing a module.

After the plate-type primary filter reaches the pressure difference value, it needs to be replaced manually, which is time-consuming and laborious. The filter of the entire cross-section module is replaced, and the workload is very large.

It can be concluded that the winding filter is functionally more convenient to maintain than the primary effect plate filter, saving labor costs. If the air volume of a fixed area is not met by the standard roller shutter filter, you can choose it. V-shaped wound filter to make up for defects.

Based on many years of professional automatic rolling filter manufacturers ‘ experience in the treatment of three wastes and exhaust gas purification, Nanjing Yixio’s rolling curtain air filter products are widely used in the purification of VOC organic exhaust gas, rubber and PVC exhaust gas, and spray exhaust gas purification. This product is a highly automated exhaust gas filtering device, which can effectively remove particulate matter in the exhaust gas and meet the emission standards. The operation is simple and the technical performance is stable. , The company has won the favor of many users with its unique and novel design concept, safe and stable purification effect, and timely and high-quality after-sales service. Roller shutter filter series products have been listed as the preferred supporting suppliers of engineering projects by many design institutes, scientific research institutes, well-known coating equipment manufacturing companies, and environmental engineering companies. It is very suitable for use in mechanical processing industry, petrochemical industry, chemical pharmaceutical industry, municipal waste industry, etc.
Working principle: The mainstream exhaust gas filtration methods in the market are divided into two types: dry and wet. In the past, the wet method was mostly used. Because of the disadvantage of a lot of sewage, sewage discharge has become a new discharge problem. Now it has been dry. The filter replaces. The wound filter is the mainstream dry exhaust gas filtering method in the current market. Because the filter material can be replaced automatically, it is durable, and the filter material is synthetic polyester fiber, the volume of the waste filter cotton after discarding is quite small, and it is very easy to handle.
In the waste gas treatment process, the gas after water treatment is effectively filtered by the automatic rolling curtain filter to remove large particles of impurities and paint mist, and effectively protect the stable and effective operation of the back-end purification equipment and activated carbon filter equipment. Without the pre-filtering function of the roller shutter air filter, the activated carbon tower at the back end is easily scrapped as a whole, and the operating cost is considerable. Dust will be effectively filtered when the air passes through the roller blind filter cotton. When the dust on the filter becomes more and more, the resistance becomes larger. When the limit value preset by the PLC system is exceeded, the system will start the motor operation, drive the special roller blind filter filter material to rotate, unfold the clean filter cotton on the new side, and carry out a new round of filtering work.
Control features: The automatic roller shutter filter adopts advanced PLC control program to complete the automatic control of the entire refueling process without any human intervention. The external random electric control cabinet can monitor and adjust the control value outside the cabinet. The reserved motor operation, missing filter material and other signal dry contacts allow the central control room to easily monitor the operating status of the field equipment.
Structure: The main structure of the automatic roller shutter filter is divided into two types: ordinary vertical design and patented horizontal design. The horizontal design has obvious advantages such as high effective utilization of space, no need to stop the machine for new materials, and no need to enter the pipeline for maintenance. It is the preferred structural style in the integration of pipeline exhaust gas treatment equipment.
Technical Parameters:
Handling air volume: Determined according to user design air volume, mostly in the range of 6000~100000CMH air volume
The number of times that the roller blind filter can be used: less than 10 times

Filtration efficiency: G3

Initial resistance: [email protected] /s
Final resistance: [email protected] /s
Motor power: 200W

With the progress of the air filtration industry, many types of air filters have been derived. Among them, the air duct type automatic rolling curtain filter is the more outstanding one, and the application range is also the most widely used type, so its market is also The biggest one, all users will give praise after use, why is this the case? Because it has very unique advantages, such as the following aspects:

First, what has to be said is the efficiency of dust removal and filtration of the roller blind filter. The use of a wind pipe type automatic winding filter can filter the coarse particles with a content of more than 85% in the air at one time, so that the air at the air outlet can be filtered. The quality is excellent and reliable, which greatly reduces the frequency of replacement of the rear filter, and is a reliable operation for the safe and effective operation of the entire air treatment system.

Second, the unique design of the air duct type automatic roller shutter filter, seamlessly connected with the air inlet pipe, eliminates the need for environmental protection engineers to consider the installation of the roller shutter filter on site, and the goods can pass through the interface flange after reaching the site It is directly sealed with the pipelines and equipment on site, which is convenient and quick, and its installation efficiency is also staggering.

Third, the patented filter material quick change function of the air duct type automatic rolling screen filter , enters the inside of the pipeline when customer maintenance is not required, and only needs to complete a series of maintenance work such as overall equipment debugging and filter material replacement outside the box. The design that does not need to enter the pipeline is currently favored by customers in various air treatment projects such as chemical industry, painting, VOC gas filtration, RTO regenerative incinerator, etc. With the current domestic emission standards becoming stricter and more standardized, our roller shutter filter series products have been sought after by environmental protection engineering companies.

Fourth, the air duct type automatic rolling curtain filter is energy-saving and environmentally friendly. The data shows that under normal working conditions, its working rated power is only 100w-200W. Under daily standby conditions, there is almost no power consumption. When the material reaches the value of the replacement pressure difference, the power consumption of the starter motor product will last only a few minutes. This shows that its later power operation cost is quite low.

Fifth, the new super-wide and super-wide new filter material storage device of the air duct type automatic rolling screen filter can store the filter material used by customers for 5-15 times. Greatly save the cost of manpower operation in the later stage. Nowadays, as labor costs continue to rise, this innovative filter type has been recognized by customers with large ventilation areas.

Sixth, the air duct type automatic rolling curtain filter provides the possibility of online replacement. As we all know, for some chemical and coating production lines, the cost of downtime for maintenance of the entire system is quite huge. The introduction of the duct type roller shutter filter can be said to solve the problem of online replacement.

These advantages are only more obvious. Specifically, the air duct type automatic rolling shutter filter has many advantages, because in this case, it is not an article that can be described one by one, but only these Advantages are enough to satisfy users and make them feel worthwhile, don’t you think?
