Description

An easy-to-clean bag filter

technical field

The utility model belongs to the technical field of bag dust collectors, in particular to a bag dust collector which is easy to clean.

Background technique

The bag filter is a dry dust filter device. Its working principle is that the dusty flue gas passes through the filter material, and the dust particles are filtered out. The filter material captures coarse dust mainly by inertial collision, and captures fine dust mainly by Diffusion and sieving, and those dust with large particles and large specific gravity will settle under the action of gravity and fall into the ash hopper.

When the bag filter is used for a certain period of time, a large amount of dust will accumulate inside. The existing bag filter is troublesome to disassemble and it is not convenient to clean the accumulated dust inside. After too much dust accumulates, it is easy to block the filter and affect the filtration efficiency. There is also a risk of explosion.

Patent No. CN214019726U discloses a bag filter for medical waste incineration tail gas treatment. When cleaning the inner wall of the bag filter through the set cleaning parts, motor and water guide steel pipe, the end of the water guide steel pipe located outside the bag filter is passed into The cleaning liquid is injected into the cleaning component, and the motor drives the connecting steel pipe to rotate with the soaked dirt brush to clean the inner wall of the bag filter, which is more convenient and thorough. Although this patent can clean the inner wall of the bag filter, it does not clean the filter. After cleaning, the dust on the filter is still difficult to clean, and the filter is one of the most important components that affect the filtration efficiency.
