Description
Technical field
The utility model relates to a kind of waste heat of boiler tail gas and reclaims desulfurizer.
Technical background
In the use procedure of boiler, because burning is complete, usually contain in the tail gas of discharge in the various gaseous contaminants that air quality is impacted, wherein SO
2flue gas quantity is maximum, impact is the widest, the SO that Industrial Boiler is discharged
2waste gas belongs to low concentration gas, generally between 0.1-0.2%.This is the waste of the energy existed in boiler use procedure and the pollution problem of environment at present, and we need to develop a kind of technology, on the one hand by the heat energy recycle of boiler exhaust gas loss; And while recovery heat, adopt desulfur technology, the SO of the discharge in absorption boiler
2waste gas, reduces disposal of pollutants, reaches energy-saving and environmental protection, cost-saving object.
Utility model content
The utility model will develop a kind of waste heat of boiler tail gas reasonable in design, with low cost, that applicability is strong to reclaim desulfurizer, adopts following technical scheme.
A kind of waste heat of boiler tail gas reclaims desulfurizer, it is characterized in that: comprise a heat exchange mechanisms, a multiple filtration mechanism be communicated with above-mentioned heat exchange mechanisms by cooling duct, demist passage and the remaining liquid recovering mechanism by remaining liquid collection conduit and above-mentioned multiple filtration mechanism connection; There is heat pipe described heat exchange mechanisms inside, and is spaced apart the two-layer up and down of independent not conducting, and the relative both sides of its lower floor comprise an inlet exhaust gas, a low temperature exhaust gas outlet; Relative both sides, its upper strata comprise a clean gas import, a clean gas outlet; Described low temperature exhaust gas outlet is communicated with described cooling duct, described clean gas import and described demist channel connection; Described multiple filtration mechanism is a cylinder type hollow housing, has an air inlet to be communicated with described cooling duct in the middle part of it, and its top is gas outlet and described demist channel connection; Down there is a funnel shaped waste water collection device at described air inlet, up have 2 layers of filtering material and a shower nozzle successively at described air inlet; Described filtering material is connected to described remaining liquid collection conduit, and is connected with described remaining liquid recovering mechanism; Spray equipment is had in described cooling duct; Demister is had in described demist passage.
The utility model has the following advantages, and 1, boiler high temperature using waste heat from tail gas can be realized reclaim, and the heat of recovery to be used, to save energy consumption; 2, the waste water of generation can be used in sweetening process, and waste water realizes closed circulation use, both significantly can reduce the discharge capacity of sulfur dioxide, can reduce again sewage disposal, Treated sewage reusing cost; 3, the utility model is reasonable in design, and fabrication and installation are convenient, have the good generalization of industry.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Detailed description of the invention
A kind of waste heat of boiler tail gas reclaims desulfurizer, comprise a heat exchange mechanisms 1, by cooling duct 2, multiple filtration mechanism 4 that demist passage 3 is communicated with above-mentioned heat exchange mechanisms 1 and the remaining liquid recovering mechanism 6 that is communicated with above-mentioned multiple filtration mechanism 4 by remaining liquid collection conduit 5; There is heat pipe described heat exchange mechanisms 1 inside, and is spaced apart the two-layer up and down of independent not conducting, and the relative both sides of its lower floor comprise an inlet exhaust gas, a low temperature exhaust gas outlet; Relative both sides, its upper strata comprise a clean gas import, a clean gas outlet; Described low temperature exhaust gas outlet is communicated with described cooling duct 2, and described clean gas import is communicated with described demist passage 3; Described multiple filtration mechanism 4 is a cylinder type hollow housing, has an air inlet to be communicated with described cooling duct 2 in the middle part of it, and its top is that gas outlet is communicated with described demist passage 3; Down there is a funnel shaped remaining liquor collecting device at described air inlet, up have 2 layers of filtering material and a shower nozzle successively at described air inlet; Described filtering material is connected to described remaining liquid collection conduit 5, and is connected with described remaining liquid recovering mechanism 6; Spray equipment is had in described cooling duct 2; Demister is had in described demist passage 3.
Boiler exhaust gas enters heat exchange mechanisms 1 from inlet exhaust gas, realize the process of heat exchange, reduce the temperature of tail gas simultaneously, by entering multiple filtration mechanism 4 after the spraying cooling of cooling duct 2, tail gas is after passing through 2 layers of filtering material, desulfurizing agent in remaining liquid recovering mechanism 6 forms liquid mist by nozzle ejection, fully mass transport process has been contacted by drop and flue gas, removed the fog with pollutant in air again by demist passage 3, chimney is led on the upper strata that clean air enters heat exchange mechanisms 1 by clean gas import.On the other hand, the liquid collection containing sulfide collected returns in remaining liquid recovering mechanism 6 and carries out chemical reaction by remaining liquid collection conduit 5, realizes the purified treatment of product.
A kind of waste heat of boiler tail gas provided the embodiment of the present invention above reclaims desulfurizer and is described in detail, for one of ordinary skill in the art, according to the thinking of the embodiment of the present invention, all will change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
