Accompanying drawing explanation
Fig. 1 is the schematic diagram of industrial smoke dedusting and waste-heat recovery device;
Wherein:
The outlet of 1-gas collection system, 2-cyclone dust collectors, 3-smoke inlet, 4-burner, 5-dog-house, 6-plasma gun, 7-high-temperature flue gas, the outlet of 8-fused materials, 9-cyclone firing cylinder, 10-how curved flue, 11-afterheat generating system, the out of stock equipment of 12-desulfurization.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is described in detail.The utility model protection domain is not limited to embodiment, and those skilled in the art make the scope that any change also belongs to the utility model protection in the scope that claim limits.
The dedusting of the utility model industrial smoke and waste-heat recovery device, as shown in Figure 1, comprise gas collection system 1 and cyclone dust collectors 2, the out of stock equipment 12 of cyclone firing cylinder 9, how curved flue 10, afterheat generating system 11 and desulfurization.Cyclone firing cylinder is provided with smoke inlet 3, burner 4, dog-house 5, plasma gun 6, high-temperature flue gas outlet 7 and fused materials outlet 8.Burner is positioned at the sidepiece of cyclone firing cylinder, and burner is installed with tangential way, and burner is solid fuel burner.Plasma gun is positioned at the middle part of cyclone firing cylinder, and dog-house is positioned at plasma gun top.How be provided with clean fuel burner in curved flue 10, clean fuel is natural gas.Afterheat generating system 11 comprises steam boiler, steam turbine and generator, and steam pipe coil established by steam boiler, and steam pipe coil is connected with steam turbine, and steam turbine is coaxially connected with generating set.Gas collection system is connected to the smoke inlet of cyclone firing cylinder by cyclone dust collectors, and high-temperature flue gas outlet is connected to the entrance of how curved flue, and how curved flue outlet is connected to afterheat generating system.The waste gas outlet of afterheat generating system and desulphurization denitration equipment connection, carry out subsequent treatment to useless flue gas.
Gas collection system collects the useless flue gas containing a large amount of dust that each unit of factory is discharged, and sends into cyclone dust collectors and carries out dedusting, isolate the big dust particle in flue gas.Flue gas enters cyclone firing cylinder by smoke inlet, and burner take fire coal as fuel, and the dust in heating and melting flue gas, to more than 1500 DEG C, makes dust liquefy and flows downward along cyclone wall.Cyclone dust removal cylinder for working gas, launches high-temperature plasma arc to provide heat to the liquid dust on dedusting cyclone wall with industrial combustible gas.Dog-house on plasma gun top drops into auxiliary material, generates cement products, go out dedusting cyclone cylinder from fused materials exit with after the liquid mix dust on cyclone wall by Arc Plasma Heating catalysis.The high-temperature flue gas removing most of dust is exported by the high-temperature flue gas bottom cyclone cylinder and enters how curved flue.Duo Wan flue corner is provided with clean fuel burner and plasma gun, with natural gas, purified gas, clean oil plant etc. for fuel, and further heating and melting and remaining dust in interception flue gas.The high-temperature flue gas of removing dust enters the waste heat boiler of afterheat generating system, heating steam coil pipe generation high temperature and high pressure steam, and drive steam turbine, drive electrical generators group generates electricity.Waste gas is gone out by waste gas outlet and is entered the subsequent treatment that follow-up desulphurization denitration equipment carries out waste gas.
