Problems solved by technology

[0004] The technical problem mainly solved by the present invention: In view of the problem that the traditional bag dust collector has the difficulty of controlling the explosion pressure and cannot return to the original position in time after the pressure is relieved, the present invention first compresses and extracts the air through the air extraction device, and then The front screen isolates the large particles, and then the isolated dust-laden air is compressed into the main dust collection room, and the airflow drives the rotary dust collector to rotate, converting the kinetic energy of the high-pressure gas into the rotation force of the rotary dust collector. Energy is required, and then the dust-laden air is absorbed and collected by rotating the dust collection bag layer by layer, and then compressed into the rear dust collection room, and finally filtered through the pipeline screen, and the adsorbed particles on the screen are reduced to the next cleanest by inertia. At the same time, the particles collected by the rotary dust collector and the missing particles generated during dust collection can be settled to the main cleaning room through the lower dust collection pipe under the action of gravity

Abstract

The invention relates to an explosion-proof bag rotating dust collection device, which belongs to the field of dust treatment. In the present invention, the air is firstly compressed and extracted through the air extraction device, and the large particles are isolated through the front screen, and then the isolated dust-containing air is compressed into the main dust collection room, and the rotary dust collector is driven by the air flow to rotate the dust collector. The kinetic energy of the high-pressure gas is converted into the energy required for the rotation of the rotary dust collector, and then the dust-laden air is absorbed and collected by the rotating dust collection bag layer by layer, and then compressed into the rear dust collection room, passing through the pipeline screen Finally filter, the adsorbed particles on the screen will drop to the secondary cleaning room through inertia, and at the same time, the missing particles collected by the rotary dust collector will settle to the main cleaning room through the lower dust collection pipe under the action of gravity. That's it. After the explosion-proof bag rotary dust collection device of the present invention is released, the dust collection bag can be restored to its original position in time, prolonging the service life of the dust collection bag, and the dust collection rate can reach more than 92%.

Description

technical field [0001] The invention relates to an explosion-proof bag rotating dust collection device, which belongs to the field of mechanical treatment. Background technique [0002] At present, the bag dust collectors used for dust control in the pulverized coal preparation system mainly include back-blowing explosion-proof bag dust collectors, gas box pulse explosion-proof bag dust collectors and high-pressure pulse spray explosion-proof bag dust collectors. Due to the tightening of emission concentration limits by the new emission standards and the optimization and improvement of the coal powder preparation process, the blowback type explosion-proof bag dust collector has been phased out, and the new production lines and renovation projects all use air box pulse explosion-proof bag dust collectors or High-pressure pulse spray explosion-proof bag dust collector. The gas box pulse explosion-proof bag dust collector is a high-voltage compartment off-line dust-cleaning ty...
