Summary of the invention:
Purpose of the utility model is to solve the problems of the prior art, provide one kind by three-level heat exchanger to tail
Gas cools down, and reduces dew-point temperature and humidity in tail gas, while the cold air when passing through smoke stack emission and after heating
Mixing further decreases the humidity of discharge flue gas and the tail gas white-smoke-removing device of saturation temperature.
In order to achieve the above object, the technical solution of the present invention is:
A kind of tail gas white-smoke-removing device, including the heat exchanger vertically-mounted by support frame, the heat exchanger includes from upper
The cold air inlet of 3 separated heat transfer devices being sequentially connected under and, each separated heat transfer device passes through input channel and wind-guiding
Pipe is connected, and the guide duct is connected with cooling blower, and high-pressure atomization spray head, the high pressure mist are mounted on the input channel
Change spray head to be connected by the delivery pipe equipped with high-pressure pump with household freezer；The side of the heat exchanger is equipped with by framework platform
Chimney is discharged, the cold wind outlet of each separated heat transfer device is connected by discharge line with discharge chimney, the discharge cigarette
Exhaust pipe is installed in chimney, the exhaust pipe is connected by connecting pipe with the offgas outlet of bottom separated heat transfer device,
Discharge outlet is also equipped in the connecting pipe.
Exhaust purifier is installed on the gas inlet of the separated heat transfer device of the top.
The heat exchanger is finned heat exchanger.
Detection mouth is offered on the exhaust pipe.
The beneficial effects of the utility model are: a kind of tail gas white-smoke-removing device of the utility model, including pass through support frame
Vertically-mounted heat exchanger, tail gas first pass through exhaust purifier before entering heat exchanger and go to be purified, and remove impurity；Heat exchange
Device includes 3 separated heat transfer devices being sequentially connected from top to bottom, and the cold air inlet of each separated heat transfer device is connected cold by pipeline
But blower is mounted on high-pressure atomization spray head on input channel, high-pressure atomization spray head can be sprayed freezed by household freezer after
Air is lowered into the air temperature of cold air inlet；Tail gas, which enters after heat exchanger, carries out heat exchange, partial condensation with cold air
Elutriation goes out, and reduces dew-point temperature and humidity in tail gas；Tail gas after heat exchange enters discharge chimney and changes after being discharged into exhaust pipe
Cold air dual disposal after heat, further decreases the humidity and saturation temperature of discharge flue gas, to reach no white cigarette discharge
Effect.
