Recently, Liaoning pellet factory consulted our company's desulfurization equipment, and I provided answers to each customer one by one. Our company undertakes the desulfurization tower project.
The working principle of the desulfurization tower produced by our company is as follows: firstly, the hot flue gas enters the pre washing tower and comes into contact with the saturated ammonium sulfate solution. During this process, the flue gas is cooled, and at the same time, ammonium sulfate crystals are precipitated due to the evaporation of water in the saturated ammonium sulfate solution. The cooled flue gas enters the SO2 absorption tower through a defogger. In the absorption tower, ammonia is mixed with water to form ammonia solution. SO2 in the flue gas is absorbed here and reacts with ammonia to produce ammonium sulfate. After desulfurization, the flue gas is discharged into the atmosphere through a 120 meter high chimney.
The ammonium sulfate solution is sent to the pre washing tower for recycling. The ammonium sulfate slurry in the pre washing tower enters the dehydration system. First, dehydrate through a hydraulic cyclone, and then filter the ammonium sulfate cake through a centrifuge. The clear liquid recovered from the cyclone and centrifuge is returned to the pre scrubber for recycling. The ammonium sulfate filter cake is sent to the granulation system, and the high-value granular ammonium sulfate fertilizer is stored in a dome shaped storage bin that can hold 50000 tons of ammonium sulfate before being transported by train or truck.
