Description

A bag dust collector with cleaning and collection functions

Technical field

The present invention relates to the technical field of bag dust collectors, specifically a bag dust collector with a cleaning and collection function.

Background technique

Bag dust collector is a dry dust filtering 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 filtration effect of fiber fabric to filter dust-containing gas. When the dust-containing gas enters the bag dust collector, the dust with large particles and heavy specific gravity will be removed due to gravity. It will settle down and fall into the ash hopper. When the gas containing fine dust passes through the filter material, the dust is blocked, thus the gas can be purified.

After searching, a bag dust collector with the publication number CN104785027B was disclosed, which has the effect of rapid and full settlement of flue gas, reducing the filtration burden of the dust bag, and the structure of the entire ash hopper is reasonable and ingenious;

After searching, a bag dust collector with the publication number CN102784526B was disclosed, which simplifies the structure of the bag dust collector and reduces the manufacturing cost of the bag dust collector;

After searching, a bag dust collector with the publication number CN108837613A was disclosed. The first solenoid valve and the second solenoid valve are controlled to open through the PLC controller, and the blowing nozzle continues to blow. The gas is sprayed through the filter bag, the air outlet pipe and the blowing nozzle. On the wall of the dust collection chamber, the dust inside the filter bag is removed and the dust attached to the wall of the dust collection chamber is discharged through the discharge pipe to prevent the gas entering during re-filtration from driving dust and causing secondary pollution to the filter bag;

Although the existing bag dust collector in the above application meets the user's needs to a certain extent, it still has certain defects in the process. For example, as dust accumulates on the surface of the filter bag, the resistance of the dust collector will increase accordingly. When the pressure difference on both sides of the filter bag is very large, some fine dust particles that have been attached to the filter bag will be squeezed out, causing the efficiency of the dust collector to decrease. In addition, some dust particles will stick to the filter bag and pass through the reaction bag. Blowing air cannot blow off the dust particles stuck to the filter bag, and after long-term use of the filter bag, the filter bag will be damaged, which will affect the collection of dust.

Contents of the invention
