The working principle of bag-type chemical fiber air filter
The working principle of bag-type chemical fiber air filterBag-type chemical fiber air filters play a large role in different industries. They are mainly used in the electronics industry, semiconductors, precision manufacturing, optoelectronics, medical pharmaceuticals, food and other industries. They have high cleanliness requirements in medicine, In civil or industrial dust-free workshops, it is used as the front-end filtration of high-efficiency filtration to reduce the load of high-efficiency filtration and extend the service life of high-efficiency filters. The specific use effects are explained in detail for you:The working principle of a bag-type chemical fiber air filter is different from that of a "screen". Due to the dust particles in the air, under the action of airflow, there will be inertial motion or irregular motion. There is a force called the "van der Waals force" between objects (that is, the adsorption force between molecules and molecular groups), which causes the dust particles entering the medium-efficiency air filter bag to adhere. The condition on the fiber surface of the air filter bag expresses the air purifying effect of the bag-type medium-efficiency air filter. In addition, smaller dust particles in the air will only adsorb each other and form larger particles when they collide with each other, and then they will sink. Therefore, the particle density of fine dust in the air is relatively stable. Interiors and walls fade slowly for this reason. Perhaps due to motion friction, the fiber filter material and dust may be charged, producing an electrostatic effect. The resistance of the bag-type medium-efficiency filter material will remain unchanged after being charged with static electricity, and the filtration effect will even be significantly improved. Static electricity will cause the dust to change its trajectory. When hitting the obstacle of the filter, the dust will be on the filter media. It will stick more firmly. |
