Abstract

The invention relates to a flue gas dust removal device and a flue gas emission and purification system and method.The flue gas emission and purification system comprises a heater, a plurality of desulfurization towers and the flue gas dust removal device, each desulfurization tower is filled with a purification medium, and a gas inlet of each desulfurization tower is connected with a gas outlet of the flue gas dust removal device in an on-off mode; the gas outlet of each desulfurizing tower is also respectively connected with the regenerated gas outlet of the heater in an on-off manner, and the regenerated gas inlet of the heater is communicated with the outside; the gas outlet of each desulfurization tower is also communicated with the outside and is used for discharging the purified flue gas to the outside; and the gas inlet of each desulfurization tower is also communicated with the outside and is used for introducing desorption gas generated in the desulfurization tower into a subsequent sulfur treatment device. The technical problem that the purification effect of flue gas generated by coal charging and coke pushing is poor is solved.

Description

technical field [0001] The present invention relates to the technical field of flue gas purification, and further relates to a flue gas dust removal device, a flue gas emission purification system and method, and in particular to a coal charging and coke pushing flue gas dust removal device, flue gas ultra-low emission purification system and method . Background technique [0002] When the coke oven is charged with coal, due to the contact between the coal and the hot furnace wall of the carbonization chamber, a large amount of dusty flue gas will be produced, which contains sulfur dioxide, raw gas and other impurities in addition to dust; During the process of pushing the cart, the burning of hot coke in contact with air will also produce a lot of smoke. Most of the smoke and dust leaked during the above-mentioned coal charging and coke pushing processes are collected by the dust removal dry pipe and sent to the ground dust removal station for dust removal treatment before...
