Bell-type baffle boiler ash water purifier

Abstract

The invention discloses a bell-type baffle boiler ash water purifier and belongs to the field of environmental protection. Sewage treatment is performed by using technologies such as swirling bell baffle reaction, suspension clarification, sedimentation of an inclined tube and high fiber ball filtration. According to the bell-type baffle boiler ash water purifier provided by the invention, a physical natural settling mode is adopted and no chemical additive is needed; a one-stage and two-stage inclined bucket thickening and pipeline pump forced ash discharge design is adopted; the defect of unsmooth sludge discharge of the same type of equipment is solved; and the overhead high-fiber filter layer effluent layout is adopted, so that the effluent is further purified.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a gray water purifier for a bell jar type baffle boiler. Background technique [0002] At present, the amount of ash and slag produced by the combustion of sugarcane sugar factories is large, and the turbidity of ash flushing water required for boiler smoke capture is ≥2500mg / L. Most of the ash flushing water of biomass boilers is naturally settled in a circulating pool, and the sedimentation ash slag efficiency is ≤40%. The high turbidity circulating gray water of the boiler is easy to cause corrosion and blockage to the centrifugal pump and dust removal system components. [0003] The circulating ash water used in the dust removal of the sugarcane biomass boiler is naturally settled in 6-8 ash accumulation ponds. Because there is no special anti-disturbance device at the mouth of the pond, the ash in the pond is disturbed by hydraulic force, and the settlement efficiency...

Problems solved by technology

[0002] At present, the amount of ash and slag produced by the combustion of sugarcane sugar factories is large, and the turbidity of ash flushing water required for boiler smoke capture is ≥2500mg / L. Most of the ash flushing water of biomass boilers is naturally settled in a circulating pool, and the sedimentation ash slag efficiency is ≤40%. High turbidity boiler circulating gray water is easy to cause corrosion and blockage to centrifugal pump and dust removal system components

[0003] The circulating ash water used in the dust removal of the sugarcane biomass boiler is naturally settled in 6-8 ash accumulation ponds. Because there is no special anti-disturbance device at the mouth of the pond, the ash in the pond is disturbed by hydraulic force, and the settlement efficiency is low. The gray water turbidity is ≥ 2500mg / L, which seriously affects the capture efficiency of boiler flue gas by hydraulic dedusting

The content of exhaust smoke and dust is ≥80mg / L, which has not reached the national industrial boiler smoke emission standard
