Buried scraper conveyor below; part of the gas after passing through the clean air main pipe is sent to the rough air fan through the back blowing dust cleaning device, and part of it flows into the atmosphere through the clean gas release device.

Preferably, the baghouse is three parallel baghouses.

Preferably, the combustible gas flowing out from the clean gas main pipe flows to gas users through the gas pipeline.

The present invention scientifically and rationally arranges the three systems of exhaust gas purification, furnace front smoke exhaust and scattered dust removal in a system framework, so that the steel structures of the original mutually independent systems are overall arranged, borrowed from each other, reduce steel consumption, save costs, and reduce effective use of space Second, the original three independent control systems can be integrated and optimized, and placed in the same power distribution room, which is convenient for management and saves management and operating costs; finally, the original three independent ash discharge systems are set in the same room , easy to seal and control, reducing dust secondary pollution.
