Abstract

The utility model relates to a purifying device for eliminating smoke, removing dust and removing sulfur, which is provided with an acid resisting liquid feeding pump which is connected with a liquid feeding pool, and a smoke wind channel. A sprayer which is communicated with the acid resisting liquid feeding pump is installed in the smoke wind channel. The sprayer is composed of a main pipe and a plurality of branch pipes which are communicated with the main pipe. Spraying holes are arranged on the main pipe and the branch pipes. One end of the sprayer, which is far from the acid resisting liquid feeding pump, is also provided with a movable wind screen and a repair manhole. The bottom of the smoke wind channel is provided with a plurality of liquid outflow grooves. The utility model has the advantages of simple structure, low cost and good effect of eliminating smoke, removing dust and removing sulfur, and can adsorb smoke of more than 98% in flue, so that Ringelman blackness in the flue reaches one to zero stage.

Description

The smoke dispersal, dust removal and desulphurization purifier

The utility model belongs to the purification technology field of flue gas.

The existing purifying and dedusting equipment that is used for coal-fired flue-gas, complex structure mostly, the cost height, what have can only remove the charcoal dirt in the coal-fired flue-gas, but can not remove deleterious acidic gas, causes atmosphere pollution; The patent No. is 99247484 smoke dispersal, dust removal and desulphurization clarifier, it is a vertical metal cylinder structure, the liquid level display is installed in bottom in hull outside, the bottom of housing is provided with Drainage pipe, filling funnel and water pump are installed on the Drainage pipe successively, top in the housing is equipped with two-layer netted spray piping up and down, the bottom of spray piping is provided with a plurality of apertures and several downward shower nozzles is installed, the outlet pipe of water pump is communicated with the spray piping of lower floor, the netted spray piping in upper strata is communicated with water supply pipe, and chimney is difficult to be installed but this equipment is laid bricks to the stove of need transformation.

The purpose of this utility model is to lay bricks on the basis of fixed buildings such as chimney not destroying former stove, provides a kind of simple in structure, and cost is low, smoke elimination, dedusting, the smoke dispersal, dust removal and desulphurization clarifier that desulfurized effect is good.

For achieving the above object, the utility model comprises the acidproof solution feed pump that is communicated with the feed flow pond, its design feature is: lay bricks at former stove and install a cigarette air channel between chimney and the boiler additional, in this cigarette air channel, the spray equipment that is communicated with acidproof solution feed pump is installed, spray equipment is responsible for by one and many arms being communicated with it constitute, all have spray apertures on the person in charge and the arm, at the deep bead that also is provided with an activity away from an end of acidproof solution feed pump, maintenance manhole

The bottom in described cigarette air channel is provided with many liquid spouts.

The utility model has the advantages that simple in structure, low cost of manufacture, and can add dust-removal and desulfurizing liquid by the feed flow pond, the dust-removal and desulfurizing liquid by the hole-shaped on corrosion resistant solution feed pump and the spray equipment nebulizes fully contacts with acidic gas in flue gas, neutralization reaction takes place, reach the effect of smoke elimination desulfurization, its doctor solution reusable edible can adsorb the flue dust in the flue gas fall more than 98%, make the lingemann blackness in the flue gas reach one to 0 grade, so smoke elimination, dedusting, desulfurized effect are good.

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

Fig. 1 is a main cutaway view of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is the perspective view of bowing of Fig. 1.

Fig. 1, Fig. 2, smoke dispersal, dust removal and desulphurization purifier shown in Figure 3, be to lay bricks at former stove to install a cigarette air channel 3 between chimney 1 and the boiler additional, the spray equipment 2 that is communicated with acidproof solution feed pump 8 is installed in this cigarette air channel 3, spray equipment 2 is responsible for by one and many arms being communicated with it constitute, all have spray apertures on the person in charge and the arm, the aperture of spray apertures is Φ 1mm, and the quantity of spray apertures is a plurality of, also is provided with deep bead 4, the maintenance manhole 5 of an activity at the end away from acidproof solution feed pump 8; The feed flow flow direction of acidproof solution feed pump 8 is distinguished and admirable to opposite with the cigarette in the cigarette air channel 3, the bottom in cigarette air channel 3 is provided with many liquid spouts 9, this liquid spout 9 is communicated with feed flow pond 6, be provided with multiple tracks partition wall 7 in the feed flow pond 6, feed flow pond 6 is separated into a plurality of overflow cisterns, is beneficial to the recycling of sedimentary taking-up and doctor solution.

Operation principle of the present utility model is: in the overflow cistern that doctor solution adds with acidproof solution feed pump 8 is communicated with, enter spray equipment 2 by acidproof solution feed pump 8, the doctor solution that spray equipment 2 sprays under the impact of cigarette wind, form vaporific, with the SO in the flue gas ₂, COx, NOx fully contact, and neutralization reaction takes place, and reaches the effect of smoke elimination desulfurization, concentration that doctor solution adds and the SO in the flue gas ₂, COx, NOx content be directly proportional, the Main Ingredients and Appearance that doctor solution adds is NaOH and Ca (OH) ₂Violent chemical reaction at high temperature takes place with above-mentioned pernicious gas, the mixed liquor of its formation enters the end overflow cistern of feed flow pond 6 away from acidproof solution feed pump 8 by liquid spout 9, test with litmus paper, when this mixed liquor shows neutral, it is taken out recycling, can not cause secondary pollution, the adding doctor solution is recycling once more.When the deposit in the cigarette air channel 3 too much influences ventilation, then open manhole 5, deposit is taken out.

Claims

1, a kind of smoke dispersal, dust removal and desulphurization purifier, comprise the acidproof solution feed pump (8) that is communicated with the feed flow pond, it is characterized in that: it also has a cigarette air channel (3), the spray equipment (2) that is communicated with acidproof solution feed pump (8) is installed in this cigarette air channel (3), spray equipment (2) is responsible for by one and many arms being communicated with it constitute, all have spray apertures on the person in charge and the arm, also be provided with deep bead (4), the maintenance manhole (5) of an activity at a end away from acidproof solution feed pump (8)
