Integrated apparatus.
Background technology
As Environmental protection requires more and more stricter, environmental protection industry has been listed in the significant terms of 13 planning
Mesh, and waste water, waste gas caused by industrial production are the main sources of environmental pollution, the waste gas of industrial discharge accounts for atmosphere pollution
More than 75%, heavy industry area even accounts for more than 87%.Major pollutants in waste gas are nitrogen oxides, oxycarbide and vulcanization
Thing.The discharge of waste gas is general all along with the waste of heat.The heat that waste gas carries is referred to as waste heat, waste heat refer to by technology because
The limitation of element, the heat that the energy-dissipating device in industrial production enterprise is not used appropriately, mainly include high-temp waste gas waste heat, cooling
Medium waste heat, high-temperature product and afterheat of slags, chemical reaction waste heat etc..Its combustion is accounted for according to the waste heat total resources of investigation every profession and trade
Expect the 17 ~ 67% of total amount consumed, and the waste heat that can recycle and few.
Utility model content
For the above-mentioned technical problem in correlation technique, the utility model proposes a kind of reclamation of stack gas afterheat and desulfurization
Integrated apparatus, to solve waste heat recovery in the prior art and desulfurizer separate that processing equipment is complicated, space-consuming is big and

To realize above-mentioned technical purpose, what the technical solution of the utility model was realized in：
A kind of reclamation of stack gas afterheat and the integrated apparatus of desulfurization, including air preheater, on the air preheater
Inlet of cold air, smoke inlet, hot air outlet and outlet flue are provided with, the outlet flue of air preheater is connected with waste heat recovery
Device, the hot air outlet connection chimney of air preheater, the waste-heat recoverer is connected with desulphurization plant by blower fan, described de-
Sulphur equipment is connected with fume extractor.
Further, the air preheater is heat pipe preheater.
Further, the air preheater is screw tube type air preheater.
Further, the waste-heat recoverer is heat pipe waste-heat recoverer.
Further, the waste-heat recoverer is shell and tube waste-heat recoverer.
Further, the desulphurization plant is double alkali method desulfurizing tower.
Further, the desulphurization plant is ammonia process desulfuration tower.
The beneficial effects of the utility model：Equipment is simple, occupy little space and production cost is low.
