What is the working principle of dust removal filter equipment?

Dust removal filter equipment is a kind of equipment for removing suspended particles in the air, its working principle mainly includes physical filtration, electrostatic dust removal and wet dust removal three ways.

Physical filtration is one of the most common working principles of dust removal filtration equipment. In physical filtration, the air passes through a channel with various filters or filters inside the equipment, and the particles in it are captured by the filter or filter, so that the particles in the air can be removed. The effect of physical filtration depends on the material and structure of the filter or filter, and the suitable filter or filter is usually selected according to the size and shape of the particulate matter.

Electrostatic dust removal is a working principle that removes particles from the air by electrostatic action. In the electrostatic dust removal equipment, through the establishment of an electric field between the plate and the electrode, under the action of the electric field, the particles in the air carry static charges, and then are attracted or repelled by the plate, so as to achieve the purpose of removing the particles. The electrostatic dust removal is suitable for the removal of fine particles, which has the characteristics of high efficiency and low energy consumption.

Wet dust removal is a working principle of removing particles from the air through a water film or water spray. In the wet dust removal equipment, the air passes through the device equipped with a water film or water spray, and the particles are adsorbed or impacted by the water film or water spray, so that the particles come into contact with the water, and are eventually absorbed by the water or settle to the bottom. Wet dust removal is suitable for all kinds of particles, and its advantage is that it can remove harmful substances in particles and gases at the same time.

The working principle of dust removal filter equipment removes particles in the air through physical filtration, electric static dust removal and wet dust removal, so as to improve air quality and ensure people's health and safety.
