Kiln and furnace high-standard discharge multi-eddy current particle dry and wet method desulphurization denitration dedusting system

Abstract

The invention discloses a kiln and furnace high-standard discharge multi-eddy current particle dry and wet method desulphurization denitration dedusting system. The kiln and furnace high-standard discharge multi-eddy current particle dry and wet method desulphurization denitration dedusting system is composed of a desulphurization denitration flocculating agent supply system (1), a eddy current low speed deduster (2), a dry method desulphurization denitration device (3), a wet method desulphurization denitration deduster (4), a dilution separator (5), an induced draught fan (6), an exhaust pipe (7), a first stage water pump (8), a second stage water pump (9), a water tank (10), a vibrating filter sieve (11), a slurry absorbing extruding dehydration machine 1 (12), and a slurry absorbing extruding dehydration machine 2(13), is capable of realizing high standard discharge of SO2, NO, and NOx dust of a plurality of kilns and furnaces. In using process, blocking is not caused, flower fan vibration is avoided, secondary pollution is avoided, the performance is stable and reliable, and operation cost is low.

Description

1. Technical field [0001] The invention belongs to the technology of preventing and controlling air pollution by furnaces and kilns. 2. Background technology [0002] At present, the flue gas treatment of furnaces generally adopts bag dust removal first and then desulfurization tower desulfurization, or first electrostatic precipitator and then desulfurization tower desulfurization, denitrification and dust removal cannot be carried out at the same time, the CaSO produced by the desulfurization tower 4 The new dust makes the emission not meet the national dust emission requirements. When encountering higher temperature kilns, coolers need to be added, which increases the manufacturing cost of dust removal equipment. The high-standard discharge multi-vortex particle dry-wet desulfurization, denitrification and dust removal system of the kiln can simultaneously realize the high-standard discharge of desulfurization, denitrification and dust removal, and is not limited by the e...
