Description

A bag filter with cleaning function

technical field

The utility model relates to the technical field of dust removal equipment, in particular to a bag dust collector with a cleaning function.

Background technique

The bag filter is also called bag filter and bag filter. With the improvement of modern research and development technology, the bag filter has become the most widely used dust removal equipment, among which the pulse bag filter has become the most important bag filter. The type of filter, the pros and cons of the bag filter are related to many factors, but it mainly depends on the filter material. The filter material of the bag filter is the cloth or felt made of synthetic fiber, natural fiber or glass fiber. The felt is sewn into a cylindrical or flat filter bag, and the filter material suitable for the application conditions is selected according to the properties of the flue gas. Usually, when the flue gas temperature is lower than 120 ℃, the filter material is required to have acid resistance and durability. Polyester flannel and polyester needle-punched felt are often used. When dealing with high-temperature flue gas, graphitized glass fiber cloth is mainly used. In some special cases, carbon fiber filter material is used. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, and the dust-containing gas is filtered by the filtering effect of the fiber fabric. When the dust-containing gas enters the bag filter After the filter, the dust with large particles and heavy specific gravity settles down due to the action of gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is blocked and the gas is purified, but the existing cloth bag The dust collector will continue to accumulate dust on the inner wall of the dust collecting box and the dust removal bag, which will significantly reduce the efficiency of the dust collector and make the dust removal effect worse.
