Abstract
The utility model discloses a boiler flue gas treatment system. The boiler flue gas treatment system comprises a water film dust collector, a sewage sedimentation tank, a circulating pump, an induced draft fan and a chimney, wherein the water film dust collector is connected with the sewage sedimentation tank and the induced draft fan; the circulating pump is connected with the sewage sedimentation tank; the induced draft fan is connected with the chimney; the water film dust collector forms a complete water film covering an induced air passage within the passage; the sewage flowing out from the dust collector is sedimented and purified in the sewage sedimentation tank; the sedimented and purified water in the sewage sedimentation tank is pumped out by using the circulating pump and pumped back to the water film dust collector to be recycled; the induced draft fan is used for inducing air for the boiler; the chimney is used for discharging flue gas; and the flue gas with dust removed is exhausted to atmosphere. By using the boiler flue gas treatment system disclosed by the utility model, the granular fume in the boiler flue gas is captured to reduce the pollution to the atmosphere.
Description
Technical field
The utility model relates to a kind of treatment system, particularly a kind of boiler smoke treatment system.
Background technology
The flue gas that boiler combustion produces is extracted out by air-introduced machine traditionally and is arranged in atmosphere via economizer, air-introduced machine, chimney.The shortcoming of this structure is that air quality descends because not through handling, the graininess flue dust in the flue gas directly enters in the air, and the result causes atmosphere pollution.
The utility model content
The utility model technical problem to be solved provides a kind of, and it catches the graininess flue dust in the boiler smoke, reduces the pollution to atmosphere.
For solveing the technical problem, the utility model provides a kind of boiler smoke treatment system, it is characterized in that; It comprises water dust scrubber, detention tank, circulating pump, air-introduced machine, chimney; Water dust scrubber is connected with detention tank, air-introduced machine, and circulating pump is connected with detention tank, and air-introduced machine is connected with chimney; Water dust scrubber forms the complete moisture film that covers passage in its air-inducing passage, detention tank will precipitate purification from the sewage that deduster flows out the pond; Circulating pump is extracted the water after deposition purifies in the detention tank out, returns water dust scrubber again and recycles; Air-introduced machine is used for boiler air inducing; Chimney is discharged flue gas, and the flue gas after the dedusting is arranged to atmosphere through this.
The positive progressive effect of the utility model is: the utility model is caught the graininess flue dust in the boiler smoke, reduces the pollution to atmosphere.
Description of drawings
Fig. 1 is the structural representation of the utility model one embodiment.
The specific embodiment
Lift a preferred embodiment below, and combine accompanying drawing to come the clearer the utility model of intactly explaining.
As shown in Figure 1; The utility model boiler smoke treatment system comprises water dust scrubber, detention tank, circulating pump, air-introduced machine, chimney; Water dust scrubber is connected with detention tank, air-introduced machine, and circulating pump is connected with detention tank, and air-introduced machine is connected with chimney; Water dust scrubber forms the complete moisture film that covers passage in its air-inducing passage; When boiler air inducing passed through from here, the graininess flue dust that wherein contains was caught by moisture film and is flowed out from the deduster bottom with water, flows to detention tank.Detention tank will precipitate purification from the sewage that deduster flows out the pond.Circulating pump is extracted the water after deposition purifies in the detention tank out, returns water dust scrubber again and recycles.Air-introduced machine is used for boiler air inducing.Chimney is discharged flue gas, and the flue gas after the dedusting is arranged to atmosphere through this.
The operation principle of the utility model boiler smoke treatment system is based on flue dust characteristic soluble in water, adopts moisture film to catch the graininess flue dust in the boiler smoke, and efficient can reach 95%-98%.The specific practice of the utility model boiler smoke treatment system is in the middle of the flue of air-introduced machine and economizer, to set up a water dust scrubber; Water dust scrubber is annular hollow-core construction; A plurality of nozzles are installed around portion's annular space within it; Supply water by circulating pump,, in annular space, form one moisture film through the nozzle ejection; When from then on flue gas passed through, the graininess flue dust major part that wherein contains was caught by moisture film and is flow in the detention tank with water, natural sedimentation in the pond then; Sediment is pulled otherwise processed out with the mud grab bucket, and gets in the water dust scrubber with the circulating pump extraction through the more peace and quiet water of post precipitation again, and circulation reaches the purpose of flue gas ash removal so repeatedly.
The utility model boiler smoke treatment system adopts special nozzle, is beneficial in the water dust scrubber smoke dust duct, form complete stable moisture film, finally guarantees good dedusting effect and working stability.The consumer of the utility model boiler smoke treatment system has only a circulating pump, and the maintenance link is few, makes the whole system consuming little energy, and be easy to build, maintenance is easy to use.
Though more than described the specific embodiment of the utility model; But those skilled in the art is to be understood that; These only illustrate, and under the prerequisite of principle that does not deviate from the utility model and essence, can make numerous variations or modification to these embodiments.Therefore, the protection domain of the utility model is limited appended claims.
