Further, this device also comprises an ammoniacal liquor thinning tank, the import of described ammoniacal liquor thinning tank is communicated with the upper end of ammoniacal liquor storage by pipeline, the outlet of ammoniacal liquor thinning tank is also reclaimed pump by pipeline through ammoniacal liquor and is communicated to tank used for storing ammonia, because need prevent the volatilization of ammoniacal liquor in the tank used for storing ammonia, generally can feed compressed air, guarantee pressure, but ammoniacal liquor to volatilize still, make that pressure is excessive in the tank used for storing ammonia, generally need necessarily discharge, directly be discharged in the air and can cause waste, so it is passed into the ammoniacal liquor thinning tank, in the ammoniacal liquor thinning tank water is housed, ammonia is passed in the water and namely can dissolves, and is passed at last to continue in the tank used for storing ammonia to use again.
Further, above-mentioned high-temperature flue gas entry place is provided with an atomizing blower fan, high-temperature flue gas entry namely is communicated to outside fume emission device by the atomizing blower fan, and the atomizing blower fan can make the high-temperature flue gas of certain flow, pressure enter in the ammoniacal liquor evaporimeter, guarantees evaporation effect.
Further, the ammoniacal liquor exit of above-mentioned tank used for storing ammonia is provided with the ammoniacal liquor delivery pump, and the ammoniacal liquor of certain flow, pressure is entered in the ammoniacal liquor evaporimeter, guarantees evaporation effect.
Described tank used for storing ammonia is provided with ammonia inlet, and the ammonia inlet place arranges the ammoniacal liquor pump of unloading, and ammonia inlet is communicated to outside ammoniacal liquor tank car by the ammoniacal liquor pump of unloading, and makes that this device can non-stop run.
The beneficial effects of the utility model are: be converted in the process of ammonia carrying out ammoniacal liquor, the high-temperature flue gas that the heat that needs directly adopts boiler to produce so not only provides cost savings, and has also avoided the waste of heat in the high-temperature flue gas.
