The filtration mechanism of the cartridge type dust collector is the result of a comprehensive effect such as gravity, inertial force, collision, electrostatic adsorption, and sieving. When the dust and dust containing gas enters the dust collector through the air inlet, the larger dust particles decrease due to the cross-sectional area, and the wind speed decreases, and the direct sedimentation; the smaller dust and dust particles are retained by the filter cartridge on the surface of the filter cartridge. The purified gas passing through the filter cartridge is discharged by the induced draft fan through the air outlet. As the filtration continues, the smoke and dust on the surface of the filter cartridge accumulate more and more, and the resistance of the filter cartridge increases continuously. When the resistance of the equipment reaches a certain limit, the dust and dust accumulated on the surface of the filter cartridge need to be removed in time; Under the action of compressed gas, the back-flushing filter cartridge removes the dust and dust adhering to the surface of the filter cartridge, regenerating the filter cartridge, and repeating the filtration to achieve continuous filtration to ensure continuous and stable operation of the equipment.
The structure of the filter cartridge dust collector is composed of an air inlet pipe, an exhaust pipe, a tank, a ash bucket, a dust removing device, a flow guiding device, a flow distribution distribution plate, a filter cartridge and an electric control device, similar to the air box pulse bag dust removal. structure.
The arrangement of the filter cartridge in the dust collector is very important. It can be arranged vertically on the box flower board or on the flower board. The vertical arrangement is reasonable from the viewpoint of the cleaning effect. The lower part of the plate is a filter chamber and the upper part is a gas chamber pulse chamber. A flow distribution plate is installed at the inlet of the precipitator.
1. Compact structure and easy maintenance; the filter cartridge has a long service life and can be used for two years or longer; the dust removal efficiency is high, up to 99.99%.
2, suitable for use under a variety of working conditions; according to the characteristics of dust, filter cartridges of different materials are used to solve the problem of dust control;
3, building block structure, can form the required processing air volume; save compressed air consumption, compared with the conventional pulse dust collector, the blowing pressure can be reduced by 20% ~ 40%.
