In recent years, more and more attention has been paid to the environmental pollution caused by the electric power industry. As for electricity production is high in our country, so the SO2 pollution to the environment is particularly significant. The desulfurization process of various kinds, currently has more than 200 kinds, including wet flue gas desulfurization technology in developed countries after 20 years of application, has the following advantages more prominent compared with other process: the long-term application in thermal power plant desulfurization efficiency and experience; the utilization rate is high; the availability of good. At present, there are about 85% of wet desulfurization equipment in the world, which shows that the utilization rate is very high. The design of glass steel desulfurization tower selection and performance parameters in wet desulfurization process is very important, it relates to the desulfurization efficiency and the service life of the tower, the glass steel desulfurization tower of acid (pH), the ratio of gas to liquid (L/G), analyze the characteristics of flow field, scaling properties, and provide reference for the selection and design of glass steel desulfurization tower.

Wet desulfurization process principle. The whole process of wet desulfurization process includes cooling, absorption, reheat, gypsum recycling, raw material modulation and other processes. Sulfur dioxide in flue gas in glass steel desulfurization tower and calcium carbonate absorption liquid gas-liquid contact. The reaction is as follows: glass steel desulfurization tower: CaCO3+SO3+12H2O CaSO3 - 12H2O+CO2 CaSO3 - 12H2O+32O2+32H2O CaSO4+2H2O2: oxidation tower.
Glass steel desulfurization tower has the following characteristics: 1 belongs to low temperature and low pressure and large time constant; the pH value and the concentration of the liquid absorption effect of desulfurization efficiency; it is very corrosive fluid handling equipment, so the tower prone to fouling, clogging and corrosion. Therefore, in the selection of glass fiber reinforced plastic desulfurization tower should be fully considered, not only to have a higher desulfurization efficiency, limestone excess rate can not be too high, otherwise it will be serious scaling, affecting the service life of the tower. In the design should pay attention to: the dirt is difficult to attached, simple and less liquid retention tower structure; through the test control absorption reaction pH value range and the absorption liquid vapor liquid ratio, in improving the desulfurization rate and reduce the rate of excess limestone; analysis of glass steel desulfurization tower by numerical simulation choose the best, the velocity of optimum allocation of absorption liquid, the absorption liquid can be evenly distributed, to prevent drift, so as to improve the desulfurization efficiency, reduce the fouling occurred.
