FRP desulfurization tower series
Kiln desulfurization tower
Kiln desulfurization and dust removal tower: First, in a hot flue gas scrubber, contact with a saturated ammonium sulfate solution, the flue gas is cooled in the process, at the same time, due to the evaporation of the saturated ammonium sulfate solution and the precipitation of ammonium sulfate crystals. The cooled flue gas enters the SO2 absorption tower through the mist eliminator. In desulfurization absorption tower, ammonia and water mixed ammonia solution. Sulfur dioxide in the flue gas is absorbed and reacts with ammonia to form ammonium sulfate. Finally, after desulfurization, the flue gas is discharged into the atmosphere at a height of 120 meters. The ammonium sulfate solution is placed in a prewash column for recovery. The ammonium sulfate slurry in the prewashing tower enters the dewatering system. Dehydration was performed by a hydrocyclone, and then an ammonium sulfate filter cake was obtained with a centrifuge. Return to prewasher from cyclone and centrifuge recovery and recycling. The ammonium sulfate filter cake is sent to the pellet system to obtain the high utilization value of ammonium sulfate fertilizer, and it can store 50,000 tons of ammonium sulfate before being transported by train or truck.
Industrial waste gas desulfurization treatment equipment, tower equipment, that is, kiln desulfurization and dust removal tower. Kiln desulfurization and dust removal tower is most widely used in granite masonry, and the principle of water film desulfurization and dust removal is applied. It is also called granite water film desulfurization filter, or ephedrine water film desulfurization agent. The advantage is that it is easy to maintain, and the effect of dust removal and desulfurization can be achieved by mixing different dust removal agents. With the development of glass and steel technology, kiln desulfurization and dust removal towers have been gradually replaced by glass steel. Compared with granite kiln desulfurization and dedusting towers, FRP kiln desulfurization and dedusting towers have lower cost, simple handling, not bad rust, and light weight, which has become the development trend of kiln desulfurization and dedusting towers. In addition, 316L stainless steel has three major advantages of corrosion resistance, high temperature resistance and wear resistance, which is one of the important trends of kiln desulfurization and dust removal towers. After years of improvement, Venturi, plate type, cyclone column type, float ball, sieve plate type, pneumatic emulsification type and other kiln desulfurization and dust removal towers have been developed. The equipment technology is mature and each has advantages and disadvantages. Enterprises can choose different ones according to their needs. Types of.
