The flue of alcohol-based fuel boiler is connected after outlet, or the mutual outlet flue of multiple tail gas treating unit and smoke inlet serial communication
Outlet, or the flue outlet of the smoke inlet parallel communication alcohol-based fuel boiler of multiple tail gas treating unit.
For making cold water with exhaust gas heat exchange fully, in each tail gas treating unit, the water (flow) direction between finned tube water tank is reverse
Exhaust emissions direction in heat exchanger tube.
Further, the hot-water outlet pipe of each tail gas treating unit can take individually to export the mode of hot water or each vent gas treatment list
The hot-water outlet pipe of unit can take the mode of Parallel opertation hot water.
Beneficial effects of the present invention:
1, the alcohol-based fuel combustion tail gas of the present invention is except mist and the automobile finned tube water tank of heat utilization device employing routine
For body making, use tap water to be inversely configured with exhaust emissions, be not required to increase kinetic pump, easy to use, exhaust temperature
Ambient air temperature can be brought down below, and can effectively remove tail gas water smoke.
2, the present invention can efficiently utilize the heat energy in tail gas, and the hot water after heating enters water tank storage, and 1 steams the alcohol of ton
Base fuel boiler waste heat from tail gas can obtain 1 ton and reach the moisturizing of 70 DEG C from 20 DEG C of heating, and heat utilization efficiency can directly improve 5%.
3, currently preferred automobile finned tube water tank has become as standard product, and purchase cost is low.

Detailed description of the invention
Technical scheme is described further by illustrated embodiment below in conjunction with the accompanying drawings.
Alcohol-based fuel boiler exhaust gas of the present invention is effectively except mist and heat-energy utilizing device, including configuration alcohol-based fuel boiler 4 (bag
Include burner 15, heat exchanger 16, steam (vapor) outlet 13, flue 7) exhaust collection use tail gas treating unit 3, described vent gas treatment
Unit 3 includes heat exchanger tube 2 and automobile H type finned tube water tank 1 (existing product), and multiple finned tube water tanks 1 are the most vertical
Being placed side by side in horizontal heat exchanger tube 2, the outlet 8 between finned tube water tank 1 and water inlet 9 is serially connected by copper pipe 12 and connects,
The water inlet 9 of leftmost side finned tube water tank 1 connects the cold water pipe 10 (running water pipe) accessed from heat exchanger tube 2, rightmost side fin
