Description

TECHNICAL FIELD

[0002] The cloth bag dust collector is a dry type dust filtering device, which is suitable for capturing fine, dry and 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. When the dust-containing gas enters the bag-type dust collector, the dust with large particles and high specific gravity is settled down due to the action of gravity and falls into the ash hopper. The gas containing fine dust is filtered through the filter material, and the dust is blocked, so that the gas is purified.

[0003] The existing cloth bag dust collector directly passes the flue gas into the cloth bag dust collector for filtering. Since the temperature of the flue gas generated in part of the production process is generally high, the flue gas with high temperature will cause certain damage to the filter bag, and the increase of the temperature of the filter bag will also affect the filtering precision of the filter bag, thereby affecting the entire production process.
