Ash hopper for bag filter

Abstract

The invention discloses a dust hopper applied to a bag-type dust collector. A dusty air charging hole is formed in the side wall of the dust hopper, wherein a dust discharging hole is formed in the lower part of the dust hopper; a pressure releasing device is arranged on the side wall of the dust hopper; an anti-static metal plate used for eliminating static electricity and spark is arranged on the inner wall of the dust hopper. According to the dust hopper applied to the bag-type dust collector, the pressure releasing device is capable of automatically releasing the pressure when the pressure in the dust hopper is excessively high, so that the safety of the bag-type dust collector is protected; by virtue of the arrangement of the pressure releasing device and the anti-static metal plate, the problem that dust in a box body and the dust hopper of the bag-type dust collector can be easily combusted and exploded is solved by the dust hopper; the safety performance of the bag-type dust collector is improved; the service life of the bag-type dust collector is prolonged.

Description

technical field [0001] The invention relates to the field of bag dust collectors, in particular to an ash hopper for bag dust collectors. Background technique [0002] Because the bag filter has high dust removal efficiency and a wide range of processing air volume, it can be used for flue gas dust removal in industrial furnaces to reduce the emission of air pollutants, and it has a simple structure, easy maintenance and operation, and ensures the same high dust removal efficiency. The cost is lower than that of the electrostatic precipitator. At present, the bag filter has been more and more widely used, but the box and the ash hopper of the bag filter are full of dust, and the dust is flammable and explosive. Combustible substances and combustible gases are complex. Generally, combustible dust is suspended in the air to form a dust cloud within the explosive concentration range. Under the action of the ignition source, the part of the dust that is in contact with the ignit...

[0002] Because the bag filter has high dust removal efficiency and a wide range of processing air volume, it can be used for flue gas dust removal in industrial furnaces to reduce the emission of air pollutants, and it has a simple structure, easy maintenance and operation, and ensures the same high dust removal efficiency. The cost is lower than that of the electrostatic precipitator. At present, the bag filter has been more and more widely used, but the box and the ash hopper of the bag filter are full of dust, and the dust is flammable and explosive. Combustible substances and combustible gases are complex. Generally, combustible dust is suspended in the air to form a dust cloud within the explosive concentration range. Under the action of the ignition source, the part of the dust that is in contact with the ignition source is first ignited and forms a small fireball. Under the action of the heat released by the burning of the small fireball, the surrounding dust is heated, the temperature rises, and the phenomenon of ignition and combustion occurs, so that the fireball will expand rapidly and form a dust explosion.
