Abstract
Description
Technical Field
[0001] This utility model relates to the field of dust collector technology, specifically to a finned self-heating dust collector jet gas heating device. Background Technology
[0002] A baghouse dust collector is a dry dust filtration device suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When the dust-laden gas enters the baghouse dust collector, large and heavy dust particles settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter media, the dust is trapped, thus purifying the gas. The dust collector mainly consists of the dust collector body, flue gas system, filtration device, and pulse-jet cleaning device.
[0003] Currently, most baghouse dust collectors use compressed air at around 0.5 MPa as the pulse-jet air source. The compressed air is drawn from the compressed air storage tank and connected to the pulse-jet device of the baghouse dust collector. Generally, the temperature of the compressed air is below 50℃. If the temperature of the unheated compressed air is lower than the dew point of the flue gas during the pulse-jet process, the moisture will condense on the surface of the filter bag and combine with the dust to form a caking layer. This leads to a decrease in the air permeability of the filter bag and a sudden increase in the system pressure difference. As a result, the cleaning airflow cannot penetrate the caking layer, and the effective filtration area of the filter bag is reduced by more than 50%. In severe cases, it can cause "bag clogging" failure, requiring the machine to be shut down for manual cleaning. Utility Model Content
