Abstract
The utility model provides a waste incineration flue gas cleaning device, including waste incinerator, waste incinerator's lower extreme is connected with slag pipeline, waste incinerator's upper end is connected with flue gas pipeline, it sprays the reaction tower to be connected with two on the flue gas pipeline, the slag cooling tank has connected gradually on the slag pipeline, the jigging machine, slag cooling tank top is provided with the de -ironing separator, the jigging machine has the slag to deposit the sump through the pipe connection, the upper portion that the slag deposits the sump is connected and installs alkali lye and carry mercury on the pipeline through pipeline and two top that spray the reaction tower, the slag deposits and still is connected with the alkali lye adjustment tank between sump and the alkali lye transport mercury. This kind of waste incineration flue gas cleaning device utilizes the basicity of waste incinerator pulp water solution to handle the acid gas among the waste incineration flue gas effectively, has clear away these the two kinds of pollutions of waste incinerator sediment and flue gas ingeniously, has reduced waste incineration flue gas's treatment cost simultaneously again effectively, and is energy -concerving and environment -protective.
Description
Technical field
The utility model relates to a kind of smoke cleaning apparatus, especially a kind of flue gas of refuse burning cleaning device.
Background technology
Municipal refuse is generally processed by the mode of landfill or burning electricity generation, but after waste incineration, can produce a large amount of flue gases and slag, and this flue gas contains a large amount of SO
2, CO
2, NO
2, NO, HCl, HBr, the sour gas such as chlorinated organics; Then containing a large amount of metal oxides such as potassium, sodium, calcium, magnesium in slag, after meeting water, a large amount of alkaline solutions can be produced; If these flue gases and slag treatment improper, new pollution can be produced, at present, flue gas of refuse burning generally adopts the method process adding manufactured chemical's product and carry out spraying, as lime, and ammonia etc., object be exactly in and acid ingredient in flue gas, also can suppress the generation of bioxin simultaneously.But, add the cost that manufactured chemical's product can increase fume treatment greatly, new pollution sources can be produced again simultaneously.
Utility model content
For solving the problem, the utility model provides a kind of flue gas of refuse burning cleaning device, the alkaline solution produced after being mixed with water by waste incineration slag dexterously neutralizes the sour gas in flue gas of refuse burning, thus complete the clean of flue gas of refuse burning, its technical scheme adopted is as follows:
A kind of flue gas of refuse burning cleaning device, comprise incinerator, can burn rubbish, the lower end of incinerator is connected with slag conveyance conduit, the upper end of incinerator is connected with smoke conveying duct, smoke conveying duct is connected with two spray reaction towers, incinerator burn away the refuse produced flue gas can by smoke conveying duct enter into spray reaction tower carry out spray process, slag conveyance conduit is connected with cooling of furnace slag pond in turn, jigging machine, cooling of furnace slag is provided with tramp iron separator above pond, incinerator produced slag of burning away the refuse can enter into cooling of furnace slag pond by slag conveyance conduit and cools, tramp iron separator above cooling of furnace slag pond can by the Ferromagnetic Impurities clearing and retrieving in slag, cooled slag enters into jigging machine, jigging machine utilizes water as separating medium, according to proportion difference in selected material, sorting can be carried out to slag, jigging machine is connected with slag settling sump by pipeline, thinner slag enters slag settling sump along pipeline and precipitates under flow action from jigging machine, after a period of time, be divided into two-layer in slag settling sump, upper strata is the aqueous solution of alkalescence, lower floor is the slag of precipitation, the top of slag settling sump is connected by pipeline with the top of two spray reaction towers and on pipeline, is provided with alkali lye and carries mercury, slag settling sump alkaline aqueous solution at the middle and upper levels enters into two spray reaction towers respectively under the effect of alkali lye conveying mercury, at twice the flue gas of refuse burning in smoke conveying duct is sprayed, thus the sour gas in flue gas of refuse burning is neutralized, complete the clean of flue gas of refuse burning.
Further, described slag settling sump and alkali lye are carried between mercury and are also connected with alkaline liquor make-up tank, suitably can allocate, thus make it reach optimum efficiency to the sour gas in flue gas of refuse burning in the concentration of alkaline liquor make-up tank to alkaline aqueous solution.
By the realization of technique scheme, flue gas of refuse burning cleaning device provided by the utility model can utilize the alkalescence of the waste incineration slag aqueous solution effectively to process the sour gas in flue gas of refuse burning, remove waste incineration slag and flue gas these two kinds pollutions dexterously, simultaneously, turn waste into wealth, significantly reduce the processing cost of flue gas of refuse burning, energy-conserving and environment-protective.
Accompanying drawing explanation
Fig. 1 provides by the utility model the structural representation of flue gas of refuse burning cleaning device, in figure, 1 is incinerator, 2 is slag conveyance conduit, and 3 is smoke conveying duct, and 4 is spray reaction tower, 5 is cooling of furnace slag pond, 6 is jigging machine, and 7 is tramp iron separator, and 8 is slag settling sump, 9 is alkali lye conveying mercury, and 10 is alkaline liquor make-up tank.
Detailed description of the invention
As shown in Figure 1, a kind of flue gas of refuse burning cleaning device, comprise incinerator 1, the lower end of incinerator 1 is connected with slag conveyance conduit 2, the upper end of incinerator 1 is connected with smoke conveying duct 3, smoke conveying duct 3 is connected with two spray reaction towers 4, slag conveyance conduit 2 is connected with cooling of furnace slag pond 5 in turn, jigging machine 6, tramp iron separator 7 is provided with above cooling of furnace slag pond 5, jigging machine 6 is connected with slag settling sump 8 by pipeline, the top of slag settling sump 8 is connected by pipeline with the top of two spray reaction towers 4 and on pipeline, is provided with alkali lye and carries mercury 9, slag settling sump 8 and alkali lye are carried between mercury 9 and are also connected with alkaline liquor make-up tank 10.In incinerator 1, slag is out transported in cooling of furnace slag pond 5 through slag conveyance conduit 2 and cools, tramp iron separator 7 above cooling of furnace slag pond 5 is by the Ferromagnetic Impurities clearing and retrieving in slag, cooled slag enters into jigging machine 6, jigging machine 6 utilizes water as separating medium, sorting is carried out to slag, thinner slag enters slag settling sump 8 along pipeline and precipitates under flow action from jigging machine 6, after a period of time, be divided into two-layer in slag settling sump 8, upper strata is the aqueous solution of alkalescence, lower floor is the slag of precipitation, the alkaline aqueous solution on upper strata enters into alkaline liquor make-up tank 10 and carries out concentration allotment, then under the effect of alkali lye conveying mercury 9, two spray reaction towers 4 are entered into respectively, when the flue gas that incinerator 1 produces enters two spray reaction towers 4 along smoke conveying duct 3, at twice flue gas of refuse burning is sprayed, thus the sour gas in flue gas of refuse burning is neutralized, complete the clean of flue gas of refuse burning.
