I. air filtration principle the adhesion between dust and filter medium. The dust particles in the air either move inertia with the air flow, or move irregularly, or move under the action of some field force. When the moving particles hit an obstacle, the van der Waals force between the particles and the obstacle makes them stick together. The filter medium material shall be able to effectively intercept dust particles without forming too much resistance to air flow. The disorderly interwoven fibers form countless barriers to particles, and the wide space between the fibers allows the air flow to pass smoothly. At present, the widely used materials include glass fiber, polypropylene fiber, polyester fiber, plant fiber and so on. The common filtration mechanism is divided into inertia principle, diffusion principle

Electrostatic force. Large particle dust makes inertial motion in the air flow. The airflow bypasses the obstacle, and the dust deviates from the airflow direction due to inertia and hits the obstacle. The larger the particle, the stronger the inertial force, and the greater the possibility of hitting the obstacle, so the better the filtering effect. Small particle dust makes irregular Brownian motion. The smaller the dust, the more intense the irregular motion, and the more opportunities to hit obstacles, so the better the filtering effect. The smaller the particles, the higher the efficiency of the filter; Large particle dust mainly moves inertia. The larger the particle, the higher the efficiency of the filter. The part of dust whose diffusion and inertia effects are not obvious is the most difficult to filter. For the filter performance, the efficiency value of the lowest filtration efficiency is the most representative. If the filter material has static electricity or dust has static electricity, the filtering effect can be significantly improved. There are two main reasons: static electricity makes dust change its trajectory and hit obstacles; Electrostatic force makes the dust stick more firmly on the medium. Filter resistance the captured dust will produce additional resistance to the air flow, and the resistance of the filter will gradually increase during use. The captured dust is integrated with the filter medium to form additional obstacles, so the filtering efficiency of the filter in use will also be improved. Most of the captured dust is concentrated on the windward side of the filter material. The larger the filter material area, the more dust it can hold, and the longer the service life of the filter. The more dust accumulated on the filter material, the greater the resistance. When the resistance is unreasonable, the filter shall be scrapped. Sometimes, excessive resistance will cause the dust captured on the filter to fly away. When this danger occurs, the filter should also be scrapped. The filter resistance increases with the increase of air flow. By increasing the area of filter material, the relative wind speed passing through the filter material can be reduced to reduce the filter resistance.
