Plate Chemical Filter is a high-efficiency air filtration device widely used in industrial, laboratory and home environments. Its working principle combines the dual mechanisms of physical filtration and chemical adsorption to effectively remove particulate matter and gaseous pollutants in the air and provide clean air.1. Physical filtration mechanismThe physical filtration part of the plate chemical filter is usually composed of multiple layers of fiber materials, such as glass fiber, polyester fiber or other high-efficiency filter media. These fiber materials capture suspended particles in the air by mechanical blocking. The specific mechanisms include:
Interception: When air flows through the filter material, larger particles are directly captured by the fiber, which is mainly for particles larger than 1 micron.
Inertial collision: Particles in the air deviate from the airflow trajectory due to inertia, hit the filter fiber and are captured, mainly suitable for medium-sized particles (0.1 to 1 micron).
Diffusion: For smaller particles (less than 0.1 micron), Brownian motion (random motion) causes them to deviate from the airflow path, and eventually collide with the filter fiber and be captured.
Electrostatic adsorption: Some filter materials have static charges, which can adsorb charged particles and enhance the filtration effect.The physical filtration mechanism mainly targets particulate pollution, such as dust, pollen, bacteria, etc., and through the co
