countercurrent pulse blowback bag filter

Usage Introduction

countercurrent pulse blowback bag filterdust cleaning adopts pulse countercurrent reverse blowing dust cleaning, and its electrical control adopts sequential controller, which has reliable performance. It is widely used in metallurgy, chemical industry, machinery, nonferrous casting, mining, asphalt concrete industry, cement, electric power, carbon black, grain processing and other working conditions. Equipment for the purification and recycling of normal temperature and high temperature dust-containing gas in enterprises.
Working principle of countercurrent pulse blowback bag filter:
Dust-containing gas enters the bag filter from the air inlet and is filtered by the outer surface of the filter bag. The purified gas flows from the inside of the filter bag to the upper chambers and is discharged from the air outlet through the long venturi. When the dust adsorbed on the outer surface of the filter bag reaches a certain value, the program controls the timing of pulse blowing, that is, the high-pressure air is sprayed to the long venturi tube and the purified gas is blown back into the filter bag to form a large pressure difference, the dust is swept down, the purpose of dust cleaning is achieved, and the resistance of the whole equipment and system is kept stable, the back-blown dust falls to the bottom of the lower box and is discharged and recycled by the screw conveyor.

Specific Features

countercurrent pulse blowback bag filter has the following characteristics:
1. countercurrent pulse blowback bag dust collector adopts pulse blowback cleaning method, which is one of the better dust cleaning effects in China at present. The upper box of the equipment is divided into 18 separate chambers, which are connected with a long venturi tube. The purpose of dust cleaning is achieved by using program-controlled pulses. The small venturi tube at the upper end of the blowpipe and filter bag is eliminated in structure, with simple structure and convenient operation and maintenance.
2. countercurrent pulse blowback bag filter separates the flower plate edge of the upper middle box into a certain tapered hole, so that it forms a smooth surface contact with the filter bag, which has good sealing performance and reduces the wear between the hole edge and the filter bag.
The 3. countercurrent pulse blowback bag filter has a simple and reasonable structure, a small footprint, and can be installed indoors and outdoors.
Compared with other domestic dust collectors, 4. countercurrent pulse blowback bag filter has the characteristics of large air volume, small system resistance, and wide application range (purification and recovery of mixed gas containing dust concentration <60g/m3 at room temperature and high temperature).
