Description

TECHNICAL FIELD

[0001] The utility model belongs to cloth bag dust collector technical field, concretely relates to a kind of pulse ash removal device for gas tank type pulse cloth bag dust collector. BACKGROUND

[0002] Cloth bag dust collector, also known as bag-type dust collector or filter-type dust collector, is a kind of dry high-efficiency dust removal equipment widely used in various industrial fields. Its working principle is based on the filtration of dust-containing gas by filter material (usually cloth bag), which blocks dust particles on the surface of cloth bag, so as to realize air purification

[0003] Gas tank pulse cloth bag dust collector body is divided into several box areas, and there are 32, 64, 96 filter bags in each box. There is a cylinder-driven poppet valve on the outlet pipe on the side of each box. When the dust collector filters dust-containing gas for a certain time, the poppet valve of the first box chamber starts to close and cut off the filtered gas flow. Then the pulse valve of the box chamber is opened, and the compressed air with a pressure greater than 0.4MPa is injected into the clean gas chamber to remove the dust on the filter bag. When this action is completed, the poppet valve is reopened to make the box chamber resume the filtering work, and the above-mentioned program is completed one by one to complete the whole ash removal action.

[0004] However, when the surface of the cloth bag is cleaned by the pulse ash removal device, the chamber needs to be closed, but this method makes the chamber unable to filter, affecting the efficiency of the gas tank type pulse cloth bag dust collector in filtering dust inside the gas.
