Description
Technical field
The utility model relates to a kind of dedusting and desulphurization integrated scrubbing tower, and the especially spray washing device of industrial circle dust-laden, sulfurous gas belongs to industrial circle dust-removal and desulfurizing scrubbing tower equipment technical field.
Background technology
At present, the discharge of industrial circle dust-laden, sulfurous gas is mainly that gas directly enters in atmosphere by chimney after bag-type dust or electrostatic precipitation, fine particle in gas is difficult for removing, and invest high, take up an area greatly, plant maintenance and operating cost are high, and especially existing dust collecting process cannot be removed the sulphur in waste gas, directly enter after atmosphere, cause air pollution.
Utility model content
The utility model object is to provide a kind of dedusting and desulphurization integrated scrubbing tower, can not only effectively remove the dirt in flue gas, and can effectively remove the sulphur in flue gas, solves the problem existing in background technology.
The technical solution of the utility model is:
A kind of dedusting and desulphurization integrated scrubbing tower, comprise smoke inlet, spraying layer, demist layer, tower body, exhanst gas outlet, collecting-tank, inclined-plate clarifying basin and clear water reserviors, tower body is provided with smoke inlet, above smoke inlet, in tower body, be provided with successively spraying layer, demist layer and exhanst gas outlet, described spraying layer comprises feed pipe and atomizer, feed pipe is communicated with atomizer, described demist layer comprises demister and backwash tube, backwash tube is communicated with demister, below smoke inlet, be provided with successively collecting-tank, inclined-plate clarifying basin and clear water reserviors, collecting-tank adds pipe to be communicated with aqua calcis, inclined-plate clarifying basin is communicated with by clear water return duct with clear water reserviors, clear water reserviors are communicated with the feed pipe of spraying layer by pipeline.
Described collecting-tank, inclined-plate clarifying basin and clear water reserviors are located in tower body, are positioned at below smoke inlet.
Described smoke inlet is located at tower body bottom, and collecting-tank, inclined-plate clarifying basin and clear water reserviors are located at tower body outside, and collecting-tank is communicated with tower body bottom by sewage return pipe, and collecting-tank is communicated with inclined-plate clarifying basin by sewage feed pipe.
The sewage feed pipe that described collecting-tank is communicated with inclined-plate clarifying basin is provided with sewage pump.
Described clear water reserviors are provided with feed pump with the pipeline that the feed pipe of spraying layer is communicated with.
Adopt the utility model, flue gas enters after tower body by smoke inlet, and the γ-ray emission convection current of the atomized water being sprayed by spraying layer and rising also fully contacts, the dust of carrying under one's arms in flue gas due to fully the contacting of water, and taken away by water, with the water (sewage) of dust, be collected together through collecting-tank, particle is effectively precipitated, precipitated by inclined-plate clarifying basin again, make sewage become clear water, enter clear water reserviors, recycle for spraying layer.For reaching better dust removing effects and preventing that water droplet from being taken out of outside tower by gas, demist layer is set above spraying layer, and flue gas is during by demist layer, and demister can effectively catch the water of carrying under one's arms in flue gas get off, thereby make flue gas become cleaner, the clean gas after washing enters atmosphere through exhanst gas outlet.If sulfur-bearing in gas, when spray, in water, add aqua calcis, sulphur in gas generally exists with sulfur dioxide form, sulfur dioxide contacts with water, can form sulfurous acid (or sulfuric acid), and sulfurous acid (or sulfuric acid) is understood rapidly and calcium hydroxide reaction generates calcium sulfite (or calcium sulfate), calcium sulfite (or calcium sulfate) can with together with dust in gas, precipitate through collecting-tank and inclined-plate clarifying basin, thereby the object of desulfurization when reaching dedusting.
The beneficial effects of the utility model are: good dedusting effect compared with traditional bag-type dust, electrostatic precipitation, can dedusting again can desulfurization, accomplish dedusting, desulfurization integrated, and invest low, take up an area little, simple in structure, plant maintenance is convenient, and cost is low, and dedusting, desulfuration efficiency are high.
