A kind of combination smoke abatement and dust control purifier

The utility model relates to a kind of environmental protection equipment, particularly is applicable to the combination smoke abatement and dust control purifier of chimney smoke and dust treatment.

Smoke contamination is to be only second to the second largest pollution that water pollutes at present in the world, and the harm of smoke contamination is many-sided, and it not only has influence on people's quality of life, and directly endanger people's living space, bring out various diseases, form acid rain, ecological environment is caused very big destruction.The method people that administer flue dust have explored for many years, have had considerable progress in general.But the electrostatic dust collection equipment investment is big, the power consumption height, and the operating cost height, and effect is not outstanding yet.Water curtain dedusting aspect, prior art is imperfection also, as the dedusting point of penetration at the boiler export place, the temperature height, wind-force is big, dust removing effects is bad, as reduce rotation speed of fan or strengthen water spray and can influence the boiler combustion effect again, the process design of dedusting simultaneously is too single, each links such as dedusting, cooling, purification is not effectively combined, therefore, effect is still not ideal enough.

The utility model is to provide a kind of composite set that smoking, dedusting, purification are combined, it can realize simple and practical, cost is low, the purpose of good dedusting effect.

The purpose of this utility model is achieved in that it provides a kind of smoke abatement and dust control purifier of combination.Comprise inspiration flue dust part, one group of water pump and air-introduced machine, one group of circulating water pool, a cyclone dust-removing storage tank, an air-return dust-removing storage tank and a purification dust-removing storage tank, three basins are interconnected, and the outlet of previous basin is the inlet of next basin.Wherein purification dust-removing storage tank is installed on the cyclone dust-removing storage tank, the return main who purifies basin stretches in the cyclone dust-removing storage tank, can spray draining, the power that promotes whole device work is one group of air-introduced machine, the spray water is supplied with by water pump, and cyclone dust-removing storage tank and air-return dust-removing storage tank bottom are connected with circulating water pool.

The course of work of the present utility model can be divided into four parts: first is an inspiration flue dust equipment, and it is made up of smoking blower fan and smoking pipeline.The inspiration flue dust mouth of soot processing device is arranged in the boiler export place at present, promptly carries out dust treatment before entering chimney, because boiler export place wind speed is fast, the temperature height can improve spray dust's effect though reduce wind speed, can influence the thermal efficiency of boiler.The increase water spray also can improve dust-laying effect, but equally also can influence the capacity of the raising and the increase sewage disposal of boiler combustion effect, and also having a significant defective is that cleaner is aging especially easily in hot environment, damages.The design is arranged in chimney outlet to flue dust inspiration inlet, temperature significantly descends when making flue dust at the boiler export place to chimney breast, and heavier soot dust granule falls after rise, and the flue dust flow velocity descends to some extent, significantly increase the chance of globule droplet absorption flue dust, helped improving dust-laying effect.The outlet of inspiration fume ducts is in cyclone dust-removing storage tank.Second portion is a cyclone dust-removing storage tank.This device is after flue dust enters, and the promotion by the rotation wind-force of the return main's of purification dust-removing storage tank water curtain sprinkling and blower fan makes water smoke fully mix with flue dust, and mixing afterwards, a part of dust powder falls into the pond.The gas that then contains flue dust water smoke enters refluence dedusting basin through the blower fan guiding.Third part is a refluence dedusting basin, and this basin is made up of shower, blinds plate washer, the funnel of falling gas, separator etc.After flue dust entered refluence dedusting basin, shower ejection water smoke, flue dust mix with water smoke after the collision of blinds dividing plate changes slow, have promoted dust and water polymerization.Enter separator through the funnel of falling gas then.Outlet that should the funnel of falling gas is in basin below the horizontal plane, in the inlet of separator, can make assorted dirt go into the pond through separating in the water, gas is risen outward by mesh, in aqueous vapor, further separate flue dust, in purifying basin, discharge again through the flue dust aqueous vapor that the general of falling the tracheae does not separate as yet fully then.The 4th part is a purification dust-removing storage tank, is made up of spray thrower, weather board, atomizing spray device, blinds plate washer, exhaust outlet etc.Enter the purification basin through the flue dust aqueous vapor after cyclone dust removal and the refluence dedusting, through the circulation circulation, water curtain sprinkling twice, collision absorption through blinds baffle plate and weather board, dust few in the flue gas lands once more, enter in the air through the flue gas after the purified treatment, the shower water in the purification basin enters circulating water pool at last in the return main falls into cyclone dust-removing storage tank.
