Description

Bag type dust collector

Technical Field

The utility model relates to a sack technical field that gathers dust specifically is a bag collector.

Background

The bag type dust collector is a dry type dust filtering device. It is suitable for trapping fine, dry, non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, the dust-containing gas is filtered by the filtering action of the fiber fabric, after the dust-containing gas enters the bag type dust collector, dust with large particles and large specific gravity is settled under the action of gravity and falls into the dust hopper, and when the gas containing fine dust passes through the filter material, the dust is blocked, so that the gas is purified. The high dust collecting efficiency of the bag type dust collector is not separated from the dust collecting mechanism of the bag type dust collector. Dust-containing gas enters the ash bucket through the guide plate by the gas inlet pipeline at the lower part of the dust collector, coarse-grained dust falls into the ash bucket under the actions of collision of the guide plate, reduction of gas speed and the like, and other fine-grained dust enters the filter bag chamber along with the gas. The deposited dust on the filter bag is removed by a gas backwashing method, and the removed dust falls into a dust hopper and is discharged to a dust conveying device through a double-layer dust discharging valve. The dust deposited on the filter bag can also be removed by adopting a method of blowing pulse airflow, thereby achieving the purpose of cleaning the dust, and the removed dust is discharged by a dust discharging device.
