Description

A bag-type dust collector for preventing filter bag clogging

technical field

The utility model relates to the technical field, in particular to a bag-type dust collector for preventing filter bags from being clogged.

Background technique

The bag filter is a dry dust filter device. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-woven felt, and uses the filter function of the fiber fabric to filter the dusty gas. When the dusty gas enters the bag filter, the dust with large particles and large specific gravity will When the air containing fine dust passes through the filter material, the dust will be blocked and the air will be purified. However, the existing bag filter has a certain limit in its ability to withstand temperature. When purifying flue gas with a higher temperature, measures must be taken to reduce the temperature of the flue gas. Some flue gas contains more water, or the dust carried by it has strong hygroscopicity, which often causes the filter bag to stick and block the filter material. Some types of bag filter workers have poor working conditions and need to enter the box when inspecting and replacing filter bags. According to the existing situation, a design is designed, which can carry out secondary cleaning of the dust adhered to the dust filter bag and difficult to remove while the dust collector is working, so as to prevent excessive dust from adhering to the surface of the dust filter bag and reduce the working efficiency of dust removal.
