Description

technical field [0001] The present invention relates to a kind of mechanical equipment, and more specifically relates to a bag filter for pulverizers. Background technique [0002] The dust removal device of the pulverizer mostly adopts the bag type dust collector. The bag filter is a dry dust filter device. After the filter material is used for a period of time, a layer of dust accumulates on the surface of the filter bag due to effects such as screening, collision, retention, diffusion, and static electricity. This layer of dust is called the first layer. During the subsequent movement, the first layer becomes The main filter layer of the filter material depends on the effect of the first layer, and the filter material with a larger mesh can also obtain higher filtration efficiency. With the accumulation of dust on the surface of the filter material, the efficiency and resistance of the dust collector will increase accordingly. When the pressure difference on both sides ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the gas flow rate at the air inlet of the existing dust removal device is large, and usually directly collides with the bottom of the dust removal bag, which is likely to cause damage to the bottom of the dust removal bag. A bag filter for a pulverizer is provided
