The square pulse bag filter is a pulse bag filter designed by the company after absorbing advanced technology from similar foreign bag filter products and improving them. This dust collector adopts the technology of high-pressure (0.5-0.7Mpa) high flow pulse valve to blow and clean the dust filter bags one by one. Compared with other single machines in China, it has the characteristics of high dust cleaning energy and efficiency. And with its small size, light weight, simple and compact structure, easy installation, and convenient maintenance (external filter type), the pulse bag filter is widely used in the purification and treatment system of dust containing gases in industries such as food, flour, grain processing, chemical, coal, flour, etc. It is an ideal equipment for dust removal.

Working principle of square pulse bag filter:
The dusty gas enters the ash hopper through the air inlet or enters the filter bag chamber through an open flange. The dusty gas is filtered by the dust collector filter bag into purified gas and enters the clean air chamber. It is then discharged by the fan through the exhaust port of the clean air chamber. Dust accumulates on the outer surface of the filter bag and continues to increase, causing the resistance of the bag filter to continuously rise. In order to ensure that the equipment resistance does not exceed 1200Pa and the bag filter can continue to work, the dust on the filter bag needs to be cleaned regularly. Dust cleaning is carried out by the PLC program controller starting the pulse valve in a timed sequence, so that the compressed air (0.5-0.7Mpa) inside the air bag is sprayed out from the blowing pipe (called primary air) through the Venturi pipe, inducing several times the surrounding air (called secondary air) into the filter bag, causing the filter bag to rapidly expand in an instant, and shaking off the dust with the reverse force of the airflow, achieving the purpose of dust cleaning.
Structure and Working Principle
1. The basic structure consists of five parts
(1) Upper box: including cover plate, fan and exhaust port;
(2) Lower box: including porous plate, skeleton, filter bag, air inlet, and maintenance door;
(3) Dust cleaning system: including controller, electromagnetic pulse valve, air bag, and spray pipe.
