Abstract
The utility model discloses a three-stage dust-removing and desulfurizing device comprising a one-stage cyclone dust remover, a two-stage bag type dust remover and a three-stage bialkali desulfurization tower; an exhaust gas inlet is formed on the one-stage cyclone dust remover; the pipe orifice of a gas outlet pipe of the one-stage cyclone dust remover is communicated with the lower part of the two-stage bag type dust remover; the pipe orifice of a gas outlet pipe of the two-stage bag type dust remover is communicated with the lower part of the three-stage bialkali desulfurization tower through an induced draft fan; a water tank is arranged below the three-stage bialkali desulfurization tower; a high-pressure water pump is arranged above the water tank; a spray pipe of the high-pressure water pump is communicated with a sprinkle device at the upper part of the three-stage bialkali desulfurization tower; and a blow-off pipe at the bottom of the three-stage bialkali desulfurization tower is communicated with the water tank. Through the use of the three-stage dust-removing and desulfurizing device, flue dust is treated through three-stage dust removing and desulfurizing to fresh exhausted gas and meet the environment-friendly requirement. The technical problems of low dust removal efficiency and environment pollution caused by flue dust in the prior art are solved.
Description
Technical field the utility model belongs to the dedusting technology field, is specifically related to a kind of 3-stage dust-removal desulfurizer.
The emission-control equipment of background technology prior art is handled through primary dust removing mostly, and waste gas gets into the one-level cyclone dust collectors through exhaust gas entrance and gets rid of through air-introduced machine.The soot processing device of this structure, heavy efficient can reach 70%, though the bulky grain flue dust is separated by cyclone dust collectors, 30% granule flue dust and a large amount of sulfide in the flue dust are still arranged in the air in addition, cause environmental pollution.
The purpose of summary of the invention the utility model is the technical problem that solves the prior art dust polluting environment, a kind of 3-stage dust-removal desulfurizer is provided, to remedy the deficiency of prior art.
To achieve these goals; The utility model 3-stage dust-removal desulfurizer, it comprises one-level cyclone dust collectors, secondary sack cleaner and three grades of two alkali desulfurizing towers, said one-level cyclone dust collectors are provided with exhaust gas entrance; The mouth of pipe of the escape pipe of one-level cyclone dust collectors is communicated with the bottom of secondary sack cleaner; The mouth of pipe of the escape pipe of secondary sack cleaner is communicated with through the bottom of air-introduced machine with three grades of two alkali desulfurizing towers, is provided with the pond below the three grades pairs of alkali desulfurizing towers, is provided with high-pressure hydraulic pump above the pond; The sparge pipe of high-pressure hydraulic pump is communicated with the spray equipment on three grades of two alkali desulfurizing tower tops, and the blow-off pipe of three grades of two alkali desulfurizing towers bottoms is communicated with the pond.
The utility model is handled flue dust through the 3-stage dust-removal desulfurization, make the gas of discharge pure and fresh, compliance with environmental protection requirements.Solved that the prior art efficiency of dust collection is low, the technical problem of dust polluting environment.
Appended drawings is the utility model structural representation.
The specific embodiment is according to accompanying drawing; It comprises one-level cyclone dust collectors 2, secondary sack cleaner 3 and three grades of two alkali desulfurizing towers 5 the utility model; One-level cyclone dust collectors 2 are provided with exhaust gas entrance 1, and the mouth of pipe of the escape pipe of one-level cyclone dust collectors 2 is communicated with the bottom of secondary sack cleaner 3, and the mouth of pipe of the escape pipe of secondary sack cleaner 3 is communicated with through the bottom of air-introduced machine 4 with three grades of two alkali desulfurizing towers 5; Be provided with pond 7 below three grades of two alkali desulfurizing towers 5; Be provided with high-pressure hydraulic pump 6 above the pond 7, the sparge pipe of high-pressure hydraulic pump 6 is communicated with the spray equipment on three grades of two alkali desulfurizing tower 5 tops, and the blow-off pipe of three grades of two alkali desulfurizing tower 5 bottoms is communicated with pond 7.
Through testing: flue dust gets into one-level cyclone dust collectors 2 through exhaust gas entrance 1, and efficiency of dust collection reaches 70%; The gas that comes out from one-level cyclone dust collectors 2 gets into secondary sack cleaner 3 through escape pipe, and efficiency of dust collection reaches 99%; The gas that comes out from secondary sack cleaner 3 carries out desulfurization through three grades of two alkali desulfurizing towers 5 of air-introduced machine 4 entering, and desulfuration efficiency reaches 95%.Dress limewash can recycle repeatedly in the pond 7.The blast of used blower fan is that 3000Pa, air quantity are 3500m
3/ h, power of motor are 37Kw.
