Absorption tower sprays diluted acid, absorbs the ammonia in tail gas.
Further, the alkali cleaning absorption tower is arranged on before pickling absorption tower, for absorbing acid gas.
Alternatively, the alkali cleaning absorption tower is arranged on after pickling absorption tower, for absorbing acid gas.
Further, the cyclone separator includes gaseous phase outlet, gas inlet, hot air inlet, cyclone separator cylinder
Body, powder collecting tank and discharge of fine material valve.It is exhaust outlet at the top of cyclone separator, air inlet has gas inlet and hot-air to enter
Mouthful, hot air inlet forms cyclone to improve tolerance.Bottom is powder collecting tank.Recycle the ferric phosphate in tail gas.
Further, the alkali cleaning absorption tower includes lye spray port, and the lye spray port is used to spray diluted alkaline, absorbs
Acid gas in tail gas.
Further, the pickling absorption tower includes acid solution spray port, and the acid solution spray port is used to spray diluted acid, absorbs
Ammonia in tail gas.
The beneficial effects of the utility model are：
Cyclone separator is employed, easy to recycle the phosphoric acid iron product in tail gas, can prevent from carrying dust in tail gas
Blocking pipeline.Tail gas is absorbed by Alkali absorption and acid after dedusting, can effectively removes SO2, SO3 and NH3 in tail gas, have
Beneficial to environmental protection.
