Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to a bag dust collector. Background Art

[0002] A bag-type dust collector is a dry dust filtering device, which is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of the fiber fabric to filter the dust-containing gas. When the dust-containing gas enters the bag dust collector, the large particles and high specific gravity dust settle due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, thereby purifying the gas.

[0003] Ordinary bag dust collectors usually do not have a heating function. Ordinary bag dust collectors will be affected by the external environment and flue gas temperature when removing dust. If the temperature inside the bag dust collector is low, condensation and water accumulation may occur, causing the bags to stick or clog, resulting in reduced dust removal efficiency. Therefore, a bag dust collector is proposed to solve the above-mentioned problems. Utility Model Content
