Description

Technical Field

[0001] This utility model relates to the field of cement preparation technology, and in particular to a kiln tail dust collection device for producing cement clinker from industrial waste residue. Background Technology

[0002] Producing cement clinker from industrial waste is a way to reuse resources. It can not only solve the problem of industrial waste disposal, but also save production costs and reduce environmental harm. Cement clinker is a semi-finished product obtained by mixing limestone, clay and iron raw materials as the main raw materials in appropriate proportions, then calcining them at high temperature until partially or completely melted, and then cooling them. Kiln tail is one of the main sources of dust pollution in cement production lines, and the total amount of exhaust gas from kiln tail accounts for a large proportion of the total exhaust gas of the entire production line.

[0003] The kiln tail dust collection device recovers waste gas. The bag dust collector in the kiln tail dust collection device traps dust particles on the surface of the filter bags through the filtration effect of the filter bags, thus achieving the purpose of dust collection. Generally, the dust particles on the surface of the filter bags are blown off by blowing air through the blowpipe. If the gas blown out of the blowpipe is too small, it will affect the dust removal. Therefore, a kiln tail dust collection device for producing cement clinker from industrial waste slag is proposed. Utility Model Content
