The desulfurization tower is a tower apparatus for desulfurization treatment of industrial exhaust gas. The desulfurization tower initially used the application of granite masonry, which utilizes water film desulfurization dust removal principle, also known as granular water film desulfurization and dust collector, or a numbwept water desulfurization and dust collector.
The advantage is that it is easy to maintain, and can achieve different dust collecting agents while achieving dust removal and desulfurization (denitrification). With the development of FRP technology, the desulfurization tower gradually changed to FRP manufacturing. Compared with the granite desulfurization tower, the glass steel desulfurization tower is low, easy to process, no rotten, light weight, therefore become the development trend of the desulfurization tower in the future. In addition, 316L stainless steel has three advantages of corrosion resistance, high temperature resistance, and wear resistance, and is also one of the important trends of the development of desulfurization towers. After years of improvement, it has been developed into a variety of desulfurization towers such as venturi, swirl type, swirl column, floating ball, sieve type, pneumatic emulsification, and equipment technology, and has its advantages. Insufficient, companies can use different types according to their own needs.
Its working principle is that the flue gas flow containing soot and thioside is passed through the imported flue into the cylinder, and the alkaline water containing OH- ions are ejected from the desulfurization column from the desulfurization column, and the integration and smoke The reverse multi-row high speed atomized water curtain increases the probability of smoke and the water of the water and the speed of the atomized droplets can be utilized to cause a high gas-liquid relative speed to ensure dust removal and desulfurization. The gas is bubbled in the liquid layer of the sieve plate, increasing the surface area and turbulent state of gas-liquid mass transfer, increases gas-liquid exchange rate of gas-liquid transmission, gas-liquid exchange in sulfur dioxide, and sulfur dioxide, and further increases desulfurization effect. The desulfurization generating material flows from the water to the bottom of the desulfurization tower, from the overflow hole, the bottom of the cylinder is under the bottom of the barrel and provided to prevent the flue gas from leaking from the bottom, and the finishing hole is easy to carry out the bottom of the cartridge.
