The desulfurization tower is mainly composed of a cylinder body, a spraying device, a sieve plate, dehydration demister, overflow hole, hole cleaning and other components, its working principle is: the flue gas containing dust and sulfur oxide flow into the cylinder through the inlet flue, alkaline water containing [OH-] ions respectively from the desulphurization tower in the lower part of the spiral nozzle, forming a plurality of rows of high-speed water curtain and reverse atomizing flue gas, increase the probability of collision of smoke of sulfur oxides and water, and make full use of the atomized droplets velocity caused by gas-liquid relatively high speed, to ensure the dust removal and desulfurization effect. At the same time the gas generated through the bubble effect on the liquid layer on the sieve plate plate, increasing the surface area of the gas-liquid mass transfer and turbulent state, increasing the mass transfer rate, sulfur dioxide and alkali occurrence of fluid gas exchange, to further improve the desulfurization effect. The desulfurization product to the bottom of the desulfurization tower with the water from the overflow hole is discharged in the bottom of the barrel cover and is provided with a seal groove to prevent leakage of flue gas from the bottom, a cleaning hole for cleaning the bottom of the barrel. After the desulfurization, the waste water is discharged from the bottom overflow hole into the sedimentation tank, and is precipitated and neutralized. After purification, the upper part of the cylinder body is led out after the mist is removed, so as to achieve the purpose of dust removal and desulfurization. Main structure of desulfurization tower
Characteristics of desulfurization tower:
1 corrosion resistance, wear resistance, high temperature resistant granite as the lining, granite processing into a circular bending plate, the overall structure is smooth and flat, reducing the resistance of the system.
2 granite with high strength, high temperature and acid and alkali resistant castable to ensure the strength of the lining material. In addition, the steel plate is protected from the outside, and the strength and the service life of the equipment are greatly increased.
3 body size is generally 1 meters every day, every day at the interface with concavo convex seam, the seam with acid clay connection, make sure not to Water Leakage.
4 sieve plate and nozzle etc. using high-quality 316L stainless steel production, internal corrosion, ensure the desulfurization effect. Main structure of desulfurization tower
