Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to a kiln head dust collecting device. Background Art

[0002] Bag-type dust collectors are often used at kiln heads to purify flue gas and collect dust. Bag-type dust collectors are a common industrial dust removal equipment. They capture particulate matter in the flue gas through filtering bags to purify the air. Particles adhering to the bags are blown away through a pulse device to ensure the permeability of the bags.

The utility model can disassemble the bag between the two sealing plates, avoid hindering the normal operation of the bag filter, achieve the effect of non-stop maintenance, improve the working efficiency of the bag filter, and facilitate the staff to replace and maintain the bag. It is highly practical and meets the market demand.

[0004] CN215962592U has significant advantages when used, but it still has some shortcomings. When the flue gas flow rate is large, the filter bag inside the bag filter is effective in filtering the dust flow, which requires the bag to shorten the cleaning cycle. The blowing process causes impact and wear on the filter bag. In addition, the high heat and corrosive substances in the flue gas cause great loss of the filter bag and reduce its service life. For this reason, we propose a kiln head dust collecting device to solve the existing problems. Utility Model Content
