Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is illustrated:
Be overall structure principle schematic of the present utility model with reference to Fig. 1, Fig. 1, the utility model provides a kind of waste gas treatment equipment, fully can carry out burning disposal to waste gas, and the heat energy of generation is utilized fully on coating line, i.e. energy-conservation but also environmental protection.
Concrete, waste gas treatment equipment of the present utility model, comprise heat economizer 3, be communicated in exhaust extraction blower fan 9, the waste gas that described exhaust extraction blower fan 9 extracts rendering, the smart painting stage produces also is delivered in heat economizer 3, and uniform temperature is preheating to from low temperature waste gas (about about 250 DEG C) in heat economizer 3, be specially 450 DEG C-500 DEG C.In the present embodiment, the heat exchanger of heat economizer 3 is jacketed type exchanger.
Heat economizer 3 diconnected has incinerator 1, incinerator 1 is undertaken adding thermal incineration by combustor 2, the concrete course of work is: heat economizer 3 is delivered to incinerator 1 and burns after low temperature waste gas is preheated to 450 DEG C-500 DEG C, the temperature that in the present embodiment, incinerator 1 sets is 750 DEG C-800 DEG C, and then the benzene hydrocarbon gase in the low temperature waste gas of preheating can be cracked into carbon dioxide and water, and produce amount of heat.After through burn after waste gas be delivered to heat economizer 3 by incinerator 1, by the heat exchange function of heat economizer 3, preheating is carried out to follow-up low temperature waste gas, after preheat, decline to some extent from the temperature of the waste gas of heat economizer 3 discharge, drop to 450 DEG C-500 DEG C from the temperature of about 700 DEG C.
The other end of heat economizer 3 is connected with combustion gas draught distributing box 4, combustion gas draught distributing box 4 is connected to air-heater 5 and fresh air heat exchanger 6, combustion gas draught distributing box 4 is divided into two parts for the high-temp waste gas (450 DEG C about-500 DEG C) transferred out by heat economizer 3, wherein a part is extracted by air-heater 5, a part is delivered to fresh air heat exchanger place 6 in addition, that is extracted by air-heater 5 is partly recycled to rendering or smart automatic doubler surface glouer, carry out rendering or essence be coated with heat, be delivered to the part of fresh air heat exchanger 6 then for the preheating to fresh air.
Concrete, fresh air is extracted by air extraction blower fan 10 and is delivered in fresh air heat exchanger 6, carry out heat exchange between high-temp waste gas in the air of circulation in fresh air heat exchanger 6 and fresh air heat exchanger 6, the air themperature after heat exchange reaches to 250 DEG C, being transported to painting machine or blowing-dry apparatus use; High-temp waste gas temperature after heat exchange is down to about 300 DEG C, is discharged by smoke evacuation air-introduced machine 7 and chimney.
Because the EGT of discharging from fresh air heat exchanger 6 is at about 300 DEG C, its temperature is still higher, there is larger heat energy, therefore the present embodiment is optimized energy recovery further, concrete, that multi-level water heater 8 is set between fresh air heat exchanger 6 and smoke evacuation air-introduced machine 7, this multi-level water heater 8 is communicated in pre-treatment circulating water wash system 11, specifically namely: after the recirculated water inflow multi-level water heater 8 of pre-treatment circulating water wash system 11, heat exchange is carried out with the waste gas of about 300 DEG C flowed out from fresh air heat exchanger 6, after recirculated water heat exchange, temperature reaches to about 60 DEG C, for the cleaning to product.Waste gas after multi-level water heater 8 heat exchange enters smoke evacuation air-introduced machine 7, and discharged by chimney, the EGT of now discharging is not high, and toxic gas in it is cleaved, can not atmosphere pollution after discharge air.
Preferably, the combustor 2 of the present embodiment is provided with automatic electronic ignition device, automatically can carry out point and fight and carry out combustion heating to incinerator.
In the present embodiment, heat economizer 3 is connected with the waste gas input of incinerator by exhaust piping and emission nozzle, and concrete, emission nozzle is arranged on exhaust piping, and the waste gas in pipeline is introduced incinerator 1.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model scope change and improve, and all should still belong within this patent covering scope.
