With the acceleration of industrialization, the problem of environmental pollution is becoming more and more serious, and the air quality is gradually declining. In order to improve air quality and ensure people's health, air filters have become indispensable equipment in many industries. This article will introduce the filtration principle of the air filter to help everyone better understand this equipment.   The main function of the air filter is to filter liquid water, liquid oil droplets and solid particles in the compressed air, so as to ensure the cleanliness of the compressed air. Its filtration principle mainly involves inertia principle, centrifugal force and filter element filtration.   The principle of inertia is that large particles move in the air stream. When the air stream encounters an obstacle, the particles deviate from the air stream due to inertia. The application of this principle in the air filter is manifested in: when the compressed air passes through the guide plate of the filter, the large particles move in the tangential direction due to the action of inertia, separate from the air stream, and are finally thrown to the inner wall of the water cup.   Centrifugal force refers to the high-speed rotating air flow, liquid water and oil and large impurities are thrown out under the strong centrifugal force. In the air filter, this principle is achieved through the bevel teeth on the deflector. The compressed air produces a strong rotation under the action of the helical teeth, so that the liquid water oil and larger impurities are thrown to the inner wall of the water cup, so as to achieve the purpose of separation.   Filter element filtration refers to filtering out small particles in the air through the microporous structure of the filter element. The filter element is usually made of porous material and has a large surface area to effectively capture particulate pollutants in the air. When compressed air passes through the filter, fine particles will be captured by the microholes of the filter, so as to achieve the purpose of purifying the air.   To sum up, the filtration principle of the air filter is mainly through the principle of inertia, centrifugal force and filter element filtration, separating the liquid water, liquid oil droplets and solid particles in the compressed air to ensure the cleanliness of the compressed air. In practical applications, air filters are widely used in air conditioning, ventilation, air purification and other fields to provide people with a healthy and comfortable breathing environment.

Measure air filters through the ability of air volume can be represented with surface wind speed or filter speed, speed response filter material through capacity, especially reflect the filtering performance of the filter, the filter speed is lower, generally will make the air filter to obtain higher efficiency (this is because the low strain rate under the condition of particle is easier to stick to and achieve filtering);The lower the filter speed allowed by the air filter, the greater the resistance of the air filter filter material.   Filter speed and surface wind speed of air filter The following are the relevant formulas and meanings of air filter speed and efficiency: Q - Air volume (m³/h) F -- The cross-sectional area of the air filter is the upwind area F - the net area of the filter material, that is, the area occupied by the removal of bonding   Resistance: The fibers cause the air to go around, creating little resistance.The sum of the resistance of countless fibers is the resistance of the air filter.The resistance of air filter increases with the increase of air flow rate. By increasing the area of air filter material, the relative wind speed through the filter material can be reduced to reduce the resistance of air filter.   After the air filter is installed Surface wind speed (u) : the velocity of air flow through the air filter section (m/s) U = Q/(F (3600) Note: In the case of a certain air volume, the larger the filtration area, the smaller the surface wind speed U Filter speed (V) : the velocity through the airflow over the filter material area (m/s) V/f = 0.028 x Q Note: in the case of a certain air volume, the larger the net area of the filter material, the lower the filter speed, so as to achieve better filtration efficiency.   Under specific air filter structure conditions, the unified reflection of surface speed and filter speed is rated air volume.Under the same cross-sectional area, it is hoped that the larger the rated air volume allowed, the better. When operating under the rated air volume, the filter speed of the air filter will be reduced, the filtration efficiency will be improved, and the resistance will be reduced.   Welcome new and old customers to inquire: 028-61295169 Whatsapp:+8618780164146 Email:trkqjh@163.com

Air filter refers to the air filter device, generally used for clean workshop, clean workshop, clean operating room, laboratory and clean room, or used for dust prevention of electronic mechanical communication equipment.Widely used in petroleum, chemical, metallurgy, electric power, machinery, light industry, textile, automobile manufacturing, electronics, food, medicine, biochemical, national defense, scientific research and other industries and departments that need compressed air purification.   Cleaning methods and steps of air filters: 1. When the surface of the filter is not very dirty, take the filter outside and blow clean it with clean compressed air on both sides. Blow and wash it until the eyes do not see dust particles in the light. 2. When the filter surface is dirty, it needs to be washed.In the general area of the water chamber (air conditioning room) with a tank into about 100 jin of water, 1 jin of bottles of detergent diluted, the filter into the tank to all submerged in the water.Rinse several times, to no pollution, and finally rinse with clean water until the water is clear, take out on the stainless steel grid to drag over the dry water, and then spread it on the shelf to dry in the shade, cool in the sun to double frequently turn in order to speed up the drying speed. 3. Clean the outer surface of the air conditioning box body and affiliated pipelines and instruments with rag every day, so that the equipment is clean and bright. 4 on the equipment of oil, glue to use cloth dip detergent to wipe off, and then clean with drinking water, leaving no trace. 5. After each replacement of the primary and medium effect filter, the internal wall panel, fan, heater, cooler, flow plate of the air conditioning unit should be thoroughly cleaned, dust, dirt and oil stains should be cleaned, and no dead Angle should be left, and then the primary and medium effect filter should be installed. 6. The internal system should be cleaned once every half a month. Wipe the internal system with a wet rag first, and then clean it comprehensively with a dry rag. 7. When replacing the HEPA filter, the four frames and surrounding areas of the installation filter should be wiped clean with wet clean cloth, and repeated three times, and the HEPA filter should be installed immediately after wiping.The HEPA filter should be unpacked on site and installed immediately after inspection to prevent dust from falling into the HEPA filter. 8. Detects the number of suspended particles in the clean room significantly exceeds the standard, and the final air volume of the HEPA filter is reduced to less than 70% of the initial air volume. 9. After HEPA filter replacement, dust particle counter detects leakage between HEPA filter and installation connection.At the same time of scanning inspection, tighten the bolt or plug the leak with epoxy resin silica gel. 10. The detection and replacement of HEPA filters should be recorded in time. 11. Leak test and verification shall be carried out after replacement of HEPA filter.   Matters needing attention for air filters: 1. After cleaning the filter cloth, if the initial resistance value of the filter is lower than the initial resistance value of the filter installed for the first time, it should not be used and replaced in time;The filter should be replaced even if the pressure difference is greater than the initial value after two times of cleaning. 2. When taking the HEPA filter, the case should be carried upside down to make the HEPA filter land smoothly. 3. After cleaning the filter, check whether it is damaged or not, and replace it in time. Do not rub, machine wash or shake dry. 4. In the cleaning process, the primary and middle effect filter should not be confused, and should be numbered in order to distinguish. 5. Each air purification system should have a set of spare filters to be replaced in time when cleaning.   Welcome to Contact us By Whatsapp /Wechat :+86 18780164146 Email Address: trkqjh@163.com / trkqjh@gmail.com

If you want to improve the sealing of the high temperature filter can only use a good bit of sealing strip and sealant.What method can be used to improve the sealing effect of high-temperature filter? In fact, the poor sealing effect of high-temperature filter is caused by many aspects, not only the quality problem of high-temperature filter itself.We'd like to talk to you about how to improve the sealing effect of high-temperature filter, so as to effectively improve the sealing effect of the filter.   1. Through the use of negative pressure leakage sealing method, the polluted air in the positive pressure space is transmitted to the negative pressure space outside the working area by means of human intervention to ensure that the working area is not polluted.   2. contact packing sealing method, this method is a sealing filler with solid gasket, such as: neoprene rubber, obturator sponge rubber plate, and liquid sealant, such as: silicone rubber, neoprene rubber, natural rubber, etc..Solid gaskets are usually sealed by mechanical compression of bolts.The compression of rubber plate is generally 30-50.Liquid sealant is sealed by filling and adhesion methods.This sealing method is also commonly used in clean rooms.   3.liquid groove sealing method, this method is in the groove frame, inject a certain height of non-Newton sealing liquid, high temperature filter mouth is inserted into the sealing liquid, so that the air passage on both sides is blocked, to achieve the purpose of sealing.This sealing method has strong reliability and easy disassembly of the filter. It is usually used for class 100, class 10 and higher clean room seals. #Hightemperaturefilter is usually from the inlet into the compressed air and into the baffle.The baffle has uniformly distributed spiral blades, such as those of a fan, which force the high-speed flow of compressed air to rotate strongly in the tangent direction of the teeth.Liquid water, oil and larger impurities mixed in the air are separated by strong centrifugal force and flow to the bottom of the cup. Remove large impurity liquid water, oil and compressed air, and further filter through the filter element to remove small solid particles, and then discharge clean compressed air from the outlet.The umbrella-shaped baffle divides the cup into upper and lower parts, and the lower part maintains a static pressure zone to prevent high-speed rotating air from inhaling the water and oil at the bottom of the cup.The water collected from the bottom of the cup is discharged through the drain valve.Install an air filter under the vertical cup.The diameter of the upper hole is too large, and the volume of the float required is also large, which will increase the structural size of the cup.If the diameter is too small, it is difficult to manufacture during injection molding.Generally, the diameter of the upper hole is 0.8 to 1.5 mm.   Welcome new and old customers to inquire: 028-61295169 QQ:1055062717, Email:trkqjh@163.com
