Abstract
The utility model provides a dust removing and desulfurizing device for a coal-fired boiler. The dust removing and desulfurizing device comprises a device body, a gas collecting tank, a reaction chamber, a plurality of liquid medicine inlet pipes, a flow guide sheet and a whirling sheet, wherein the gas collecting tank is arranged in the device body; the liquid medicine inlet pipes are mounted at the top of the device body and extend into the reaction chamber; the flow guide sheet is mounted on the wall of the bottom of the device body; the whirling sheet is mounted on the outer wall of the bottom of the reaction chamber; a heat exchanging chamber is arranged in the middle of the device body; spraying nozzles are mounted at the bottoms of the liquid medicine inlet pipes; and the spraying nozzle is mounted at the bottom of each liquid medicine inlet pipe. According to the utility model, a cyclone dust removal technology and a spray type dust removal and desulfurization technology are skillfully combined in an integrated way through the device; and the dust removing and desulfurizing device for the coal-fired boiler, provided by the utility model, has the advantages of compact integral structure, small space usage, lower device manufacturing cost and higher dust removing and desulfurizing efficiency and is more suitable for purifying flue gases of small-sized boilers.
Description
Technical field:
The utility model belongs to the dust-removing desulfurating apparatus in environmental protection field, and particularly a kind of coal-burning boiler is used dust-removing desulfurating apparatus.
Background technology:
China is coal-fired big country; Contain a large amount of dusts and sulfur dioxide in the flue gas of discharged from coal-fired boiler; If directly be disposed in the atmosphere and can cause great pollution to environment; The dust that contains in the flue gas is suspended in the atmosphere, all can produce extremely bad influence to human respiratory, atmospheric visibility and urban look etc.; And the sulfur dioxide that contains in the flue gas contacts formation acid rain, severe contamination water source and ecological environment with airborne water vapour.Along with expanding economy; Realizing the industrialized focus of protecting environment to become government and people's concern simultaneously; Have multiple dust-collecting sulfur-removing method and equipment both at home and abroad, existing dust-removal and desulfurizing mode comprises dry type, wet type and half dry type, and dedusting and desulfurization are independently carried out; Its course of work also is in two or more independently systems, to accomplish, and this dusting and desulfuring system is comparatively complicated, floor space is big, energy consumption is bigger.Though the existing report of dedusting and desulphurization integrated technology; But the dust-removal and desulfurizing mode is comparatively single; As only adopt dry type or dust-remover method, and also exist shortcoming separately, cause the effect of dust-removal and desulfurizing undesirable; And existing dust-removal and desulfurizing equipment overall structure is comparatively complicated, and system is difficult to safeguard.
Summary of the invention:
The purpose of the utility model is to overcome the deficiency of prior art, provides a kind of compact conformation, volume coal-burning boiler little, that dust-removal and desulfurizing efficient is high to use dust-removing desulfurating apparatus.
As above design; The technical scheme of the utility model is: a kind of coal-burning boiler is used dust-removing desulfurating apparatus; It is characterized in that: by body, be arranged on body inner air collector, reative cell, be installed in the body top and stretch into a plurality of soup inlet pipes in the reative cell, be installed in the flow deflector on the wall of body bottom and the spinning disk that is installed on the reative cell bottom outer wall is formed; Be provided with heat-exchanging chamber at the body middle part, spraying nozzle all be housed in the bottom of soup inlet pipe; Spraying nozzle all is equipped with in above-mentioned bottom at each soup inlet pipe.
Above-mentioned dust tank is a funnel-form, and the bottom is outlet.
The utility model has the advantages that:
1, compact conformation, reasonable in design, floor space is little; In the dust-removal and desulfurizing work that has realized miniature boiler (below 10 tons) on tens square metres the ground, the device overall cost is lower, and desulfurization and dedusting is satisfactory for result; Efficiency of dust collection is higher than 98%, and desulfuration efficiency reaches more than 85%.
2, can significantly reduce solid ash content in the lime pond, alleviated the workload of dust-remover system, reduce the workload that operating personnel excavate lime significantly, reduce operating cost.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
The specific embodiment:
As shown in the figure: a kind of coal-burning boiler is used dust-removing desulfurating apparatus, by body 10, be arranged on body inner air collector 2, reative cell 5, dust tank 8, be installed in the body top and stretch into 3,000 soup inlet pipes 1 in the reative cell, be installed in the flow deflector 7 on the wall of body bottom and the spinning disk 6 that is installed on the reative cell bottom outer wall is formed.Be provided with heat-exchanging chamber 3 at the body middle part, spraying nozzle 4 be housed, thereby in reative cell, form three grades of spray equipments in the bottom of soup inlet pipe.Above-mentioned dust tank is a funnel-form, and the bottom is outlet 9.
The operation principle of the utility model is: from the bottom of the flue gas after the dedusting through distributor chamber, heating clamber, collection chamber entering clarifier, through flow deflector, form the rising laminar condition, carry out absorption reaction.Because the multi-stage spray device is set in reative cell, flue gas is absorbed and forms water-soluble sulfate with spraying.Sulfur dioxide not only carries out in gas-liquid contacts with the course of reaction that absorbs night, also has gas-chemistry reaction, has therefore improved the absorption efficiency of sulfur dioxide.Flue gas through reative cell after in the gas drop through settlement action and flow deflector stop the whirlwind centrifugal action, tell the water smoke in the gas, get into heating clamber again, carry out exchange heat, the flue gas after heating is got rid of clarifier.The multi-stage spray absorption liquid is derived through the outlet at bottom 9 of dust tank, flows into reaction tank.
The utility model compact overall structure, floor space is little, in the dust-removal and desulfurizing work that has realized miniature boiler (below 10 tons) on tens square metres the ground; Apparatus cost is lower; And desulfurization and dedusting is satisfactory for result, and efficiency of dust collection is higher than 98%, and desulfuration efficiency reaches more than 85%.
