Abstract
The utility model relates to a fume-gas desulfurization dust remover, which is composed of a secondary bubble blowing tower, a solid-liquid separation device, a refluxing box and a high pressure pump structure. The utility model subtly uses the principle of a popular hookah to make the fume dust be decontaminated in water solution. SO2 in the fume-gas is converted into sulfur powder and recovered. The recovered water solution can be circularly applied. The utility model does not have the secondary pollution. The utility model has the advantages of small equipment investment, simple structure, low cost and convenient installation and operation. The utility model is a necessary product of a middle and small business especially a smelting business.
Description
The utility model is a kind of desulfurating dust removing device for flue gas.
Existing industrial enterprise, particularly middle-size and small-size smelting enterprise, it is simply constructed, and no fund is formed a complete and comprehensive system for collecting real estate fees under the situation of administering the SO that often brings in process of production
2Flue gas causes the serious environmental pollution and the wasting of resources.At present, for addressing this problem, enterprise adopts double conversion double absorption system sulphuric acid device mostly, and its complexes investment is bigger, and medium-sized and small enterprises are difficult to bear.
The purpose of this utility model is, a kind of SO that can make in the flue gas is set
2Be precipitated as the sulphur powder, and reclaimed, can make the flue gas that gives off reach the desulfurating dust removing device for flue gas of industrial required standard.
The utility model is finished like this, it is to be formed by froth tower, solid-liquid separator, return tank and high-pressure pump structure of secondary, the secondary tower that froths is a hollow body, in the flue gas shunting case and the aqueous solution are housed, mouth, exhaust opening and water gauge are advanced in outer setting, its bottom side connects an end of discharging tube and high pressure reflow pipe, the other end of discharging tube connects solid-liquid separator, solid-liquid separator connects return tank, return tank connects an end of liquid injection pipe, the other end of liquid injection pipe connects high-pressure pump, and high-pressure pump is connected with the other end of high pressure reflow pipe.
The utility model uses the principle of water pipe among the people cleverly, can make clarifying smoke in the aqueous solution, and with the SO in the flue gas
2Be converted into the sulphur powder and reclaimed, and can make aqueous solution cycle applications after the recovery, do not have secondary pollution is arranged, and it is little, simple in structure, cheap, easy to install to have an equipment investment, is medium-sized and small enterprises, particularly the product of smelting enterprise's indispensability.
Provide below in conjunction with drawings and Examples.
Fig. 1 is the utility model apparatus structure schematic diagram.
As shown in the figure, it is to be formed by froth tower 1, solid-liquid separator 2, return tank 3 and high-pressure pump 4 structures of secondary, froth tower 1 of secondary is hollow body, in the flue gas shunting case 5 and the aqueous solution 6 are housed, outer two ends are provided with into mouth 7 and exhaust opening 8, and the intermediate ends device has water gauge 9, and its bottom connects an end of discharging tube 10 and high pressure reflow pipe 11, the other end of discharging tube 10 connects the following position of solid-liquid separator 2, and high pressure reflow pipe 11 is connected secondary tower 1 planted agent that froths and is higher than the plane of the aqueous solution 6; Be provided with screen pack 12 in the solid-liquid separator 2, its upper and lower layering is isolated, its upper part is connected with liquid guiding tube 13, and join by liquid guiding tube 13 and return tank 3, return tank 3 is connected with liquid injection pipe 14, liquid injection pipe 14 is provided with liquid injection port 15, and is connected with high-pressure pump 4, and high-pressure pump 4 connects the other end of high pressure reflow pipe 11; Flue gas shunting case 5 is fixedly connected on froth top one side in the tower 1 of secondary, connects with advancing mouth 7 outward, and interior device has Bubble blowing tube 16, and Bubble blowing tube 16 places in the aqueous solution 6; Discharging tube 10 also is connected with threeway fluid flow tube 17, and threeway fluid flow tube 17 is connected secondary too and froths in the tower 1, and the plane of its port of export and the aqueous solution 6 is consistent; Exhaust opening 8 is equipped with air-introduced machine 18.Advance mouth, flue gas shunting case and Bubble blowing tube when the flue gas process and enter the aqueous solution, at this moment the SO in the flue gas
2After the reactant aqueous solution absorption, flow into solid-liquid splitter through fluid flow tube again, the Cosan that is produced is deposited in the bottom of solid-liquid splitter, the residue flue gas is got back to the froth sky of tower of secondary, the aqueous solution of post precipitation flows in the return tank through filter screen and drainage tube, under the effect of high-pressure pump, the aqueous solution in the return tank is injected secondary froth (water gauge just demonstrates needed water level rapidly) in the tower by the high pressure reflow pipe, and with aqueous solution high-pressure atomization, the secondary abundant haptoreaction purification of flue gas and the high-pressure atomization aqueous solution in the tower sky that froths will be reacted flue gas after being purified and be discharged by exhaust opening under the effect of air-introduced machine this moment; After the aqueous solution in the return tank reduces, can inject the new aqueous solution from liquid injection port.
