Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail, wherein:
Fig. 1 is the schematic diagram of the exhaust gas processing device of efficient sulphur removal of the present utility model.
Detailed description of the invention
As shown in Figure 1, the exhaust gas processing device of efficient sulphur removal of the present utility model, comprises tower body 1, and described tower body 1 top is provided with gas outlet 2, and described tower body 1 bottom is provided with air inlet 3, and the inherent lower position of described tower body 1 is provided with vortex board 10.The sulfur-containing tail gas of coal-burning boiler enters tower body 1 from air inlet 3, in tower body 1 after desulfurization and dust removal process, be discharged in air through the gas outlet 2 at tower body 1 top.In Fig. 1, direction shown in arrow is exhaust gas flow direction.Spray equipment is provided with in the middle part of described tower body 1, described spray equipment comprises shower 4 and some spray heads, spray head is sprayed water formation water smoke from top to bottom, after sulfur-containing tail gas enters tower body 1, helical form ascending air is formed under the guiding of vortex board 10, meet with water smoke from bottom to top, thus form water smoke layer.In tail gas, contained sulfur dioxide generates sulfurous acid with water generation chemical reaction in water smoke layer, sulfurous acid is dissolved in water, and contained dust also can depart from tail gas under the effect of water smoke layer in tail gas, water smoke containing sulfurous acid and dust can decline under gravity in tower body 1, is finally deposited on bottom tower body 1.For improving sulfur limitation effect, spray equipment can be set to multiple, and point upper-lower position arrangement in tower body 1, in the present embodiment, spray equipment is set to two, is arranged in two layers in tower body 1.
Discharge outlet 5 is provided with bottom tower body 1, also be provided with water sealed tank 6, the bottom of water sealed tank 6 is provided with entrance 61, the top of water sealed tank 6 is provided with outlet 62, entrance 61 is connected by the first pipeline 7 with discharge outlet 5, export the position of 62 positions higher than described discharge outlet 5, the difference in height exporting 62 positions and described discharge outlet 5 is 1m.Bottom tower body 1 and water sealed tank 6 be connected to form a linker by the first pipeline 7, because linker two ends liquid level is equal all the time, the liquid level of water sealed tank 6 is that the height of the outlet 62 arranged by top determines, and export the position of 62 positions higher than discharge outlet 5, also just mean that the liquid level bottom tower body 1 is higher than the position of discharge outlet 5, thus the tail gas that ensure that without desulfurization can not be escaped in air by discharge outlet 5 and goes.
Also be provided with storage cistern 11 between outlet 62 and described circulating pump 9, storage cistern 11 is arranged water inlet and delivery port, described water inlet is connected by deflector 12 with described outlet 62, and described deflector 12 is also provided with step.Because tail gas is in the condition of high temperature, so the water containing sulfurous acid and dust flowed out from tower body 1 also temperature is higher, after it flows out the outlet 62 of water sealed tank 6, after the deflector 12 being provided with step, current fully contact with air, can play certain cooling effect.
The delivery port of storage cistern 11 is connected by second pipe 8 with shower 4, second pipe 8 is provided with circulating pump 9.Water in storage cistern 11 pumps in shower 4 by circulating pump 9, thus achieves water recycling in whole exhaust gas processing device.
Also be provided with cooling tower, described cooling tower is communicated with storage cistern 11.Cooling tower carries out cooling to a certain degree to the water in storage cistern 11.Circulating water temperature is lower, can improve the effect of desulfurization and dedusting.
Some partition walls 13 are provided with between described water inlet and described delivery port.Storage cistern 11 is separated into several part by partition wall 13, first the water containing sulfurous acid and dust flowed out from tower body 1 fill the part be connected with water inlet, next part is flowed into again after having expired, finally fill the part be connected with delivery port, enter spray equipment by the second pipe 8 that is connected with delivery port and circulating pump 9 and carry out desulfurization and dust removal process.
Due to recirculated water acidity rising after a number of uses, desulfurized effect can decline, and is all provided with and adds white lime device, regularly manually add white lime above the various piece of storage cistern 11, reduces the acidity of recirculated water, ensures desulfuration efficiency.
Containing the recirculated water of sulfurous acid in storage cistern 11 with white lime generation chemical reaction, produce calcium sulfite precipitation, be deposited on bottom storage cistern 11.Above storage cistern 11, be provided with cleaning settler, be convenient to periodic cleaning precipitation.
Because storage cistern 11 is divided into several part by partition wall 13, various piece all carries out the operation of interpolation white lime to reduce the acidity of recirculated water, and the recirculated water acidity in the part be connected with delivery port is like this minimum, can ensure the desulfurized effect of recirculated water well.
Above embodiment is only not limited in order to the technical solution of the utility model to be described, all do not depart from the utility model spirit and scope any amendment or equivalently to replace, it all should be encompassed in the scope of technical solutions of the utility model.
