The Principle Of Air Filter Filtration

Hangzhou Dingteng Industrial Co.,Ltd | Updated: Jun 11, 2018

The liquid water and liquid oil droplets in the compressed air are separated and the dust and solid impurities in the air are filtered, but gaseous water and oil can not be removed.
The removal technology of particulate matter in the air mainly includes mechanical filtration, adsorption, electrostatic dust removal, negative ions and plasma method, and electrostatic electrode filtration.
Mechanical filtration generally captures particles in the following three ways: direct interception, inertial collision, and Brownian diffusion mechanism. It has a good effect on the collection of fine particles but has large wind resistance. In order to achieve high purification efficiency, the filter core needs to be dense and replaced regularly..
Adsorption is the use of large surface area and porous structure of the material to capture particulate pollutants, easy to block, for the removal of gas pollutants more significant.
