Desulfurization tower desulfurization tower design process Shandong Bo Ruite desulfurization tower

First desulfurization tower process, hot flue gas into the pre-scrubber, a saturated ammonium sulfate solution in contact with the flue gas is cooled in the process, at the same time, due to the evaporation of water in saturated ammonium sulfate solution of ammonium sulfate to precipitate crystals. Flue gas which has been cooled by mist into the SO2 absorber. In the absorber, the ammonia liquid ammonia mixed with water. SO2 in the flue gas is absorbed in this, it reacted with ammonia to form ammonium sulfate. Finally, after a flue gas desulfurization 120-meter-high chimney into the atmosphere. Ammonium sulfate solution is fed into the pre-scrubber recycling. Pre-washed tower ammonium sulfate slurry into the dewatering system. First by the water conservancy cyclone dehydration, then by centrifuge to obtain ammonium sulfate cake. Return to pre-scrubber from the cyclone and centrifuge supernatant recovered, recycled.
