Barrel type a duster The strong cleaning ability, dust removal efficiency, low emission concentration, can also be stable, reliable, and low air consumption. The efficiency of the dust collector can be expressed by the gas loss of the dust remover. Cartridge filter The dust collector is composed of filter element or pulse injection. According to the installation methods, the cartridge dust remover can be divided into inclined plug-in type, side mounted type, hoisting type and top mounted type. According to the material of the filter cartridge, the filter cartridge dust remover can be divided into long fiber polyester filter cartridge dust collector, composite fiber cartridge dust collector, anti-static cartridge dust collector, flame retardant cartridge dust collector, membrane filter cartridge dust collector, nano cartridge dust collector, etc. It is concluded that the cleaning band filter is in progress, mainly in the following forms:

1. Vibration dust cleaning mode of mechanical structure

Mechanical devices (including manual, electromagnetic vibration and pneumatic) are used to make the dust collector vibrate. The vibration frequency varies from hundreds of times per second. The dust collector is composed of filter element or pulse jet. According to the installation methods, the cartridge dust remover can be divided into inclined plug-in type, side mounted type, hoisting type and top mounted type. According to the material of the filter cartridge, the filter cartridge dust remover can be divided into long fiber polyester filter cartridge dust collector, composite fiber cartridge dust collector, anti-static cartridge dust collector, flame retardant cartridge dust collector, membrane filter cartridge dust collector, nano cartridge dust collector, etc.

2. Back blowing and dust cleaning mode of independent room

Using a sub chamber structure, the uplift or contraction force dedusting is formed from the reverse flow path switching valve chamber. This cleaning method is also working under pressure for the filter element, which means that the cleaning capacity of the filter element means that the cleaning type has low kinetic energy and comes with dynamic gas flow in special occasions.

3. Working mode of back blowing and dust cleaning by vibration

Vibration and reverse airflow cleaning column dust collector dual role, vibration dust cake loose, reverse flow of dust. There are two matching methods, so that the cleaning effect can be improved, especially for filtering particles adhering to dust. The filter element of such precipitator is basically the same type of cleaning mode of the chamber cleaning box dust collector.

4. The working mode is reverse blowing nozzle

High pressure fan or blower is used as the power of back blowing and dust cleaning. The dust remover is sprayed by moving nozzle in turn to form strong reverse air flow, which makes the dust remover deform rapidly and remove dust. It belongs to medium energy type. According to the nozzle form and its motion trajectory, it can be divided into three types: rotating back blowing, reciprocating back blowing and gas ring sliding back blowing. Rotary back blowing and reciprocating back blowing dust remover adopts external filter flat bag with frame, with compact structure.

5. Pulse jet dedusting

The power is provided by compressed air, and the blowing device is released in an instant. Through the pulse compressed air flow, the induction of the secondary air enters the dust at multiple speeds, so that the rapid expansion of dust, vibration and impact depends on the reverse cleaning gas, and the high kinetic energy energy energy is clean.
