Limestone powder production line, the limestone desulfurization agent production line, the desulfurizer of calcium carbonate production line, the calcium oxide desulfurizer production line, the calcium hydroxide powder production line. I plant to first-class technical team, professional installation team. Now take dozens of large and medium-sized production line. Products meet the national standard of desulfurizer. In 2013, at the beginning of the New Year in most areas of China the serious fog weather, wide range of duration is long, is unprecedented in our country. Bureau experts point out that the fog haze weather appears mainly in coal is the largest in China. As countries to increase the environmental requirements strength and pm2.5 air quality further recognition and evaluation. I've been on the air quality of environmental protection has been seriously, for enhanced with coal desulfurization of enterprise requirements. So the desulfurization industry in the future the demand of the market as the change of policy and also get an unprecedented growth. Desulfurizer as consumables of desulfurization link, is an estimate of the demand of market. And calcium desulphurization efficiency and can be recycled, determines the dominance of calcium desulfurization. Limestone powder market research shows that limestone powder mineral resources in our country, accounts for over 64% of the world's total reserves, is a kind of natural resource advantages. As foreign materials, high-grade calcium carbonate fillers to enter the Chinese market, promote the domestic technological progress, speed up the deep processing of calcium carbonate in China's rapid growth, and rapid development towards diversification, specialization, refinement, expand the application field of opening more use of calcium sulphate chemical and physical stability achieve desulfurization, raw material is limestone, lime hydrate, etc., the first is to dissolve SO2: SO2 + H2O = H2SO3, H2SO3 = HSO3 - + H +, HSO3 - = H++ SO32 - with limestone dissolution: CaO + H2O = Ca (OH) 2, Ca (OH) 2 = Ca2 + + 2 OH -, the two kinds of solution for chemical absorption of SO2 dissolved: Ca2 + + SO32 - = CaSO3, CaSO3 + H2O (1/2) = CaSO3 · H2O (1/2). Oxidation of liquid: HSO3 - + O2 (1/2) = H++ SO42 -, Ca2 + + SO42 - = CaSO4 left and CaSO4 + 2 h2o = CaSO4 · 2 h2o left the final product is CaSO4 · 2 h2o left (gypsum), is a kind of stable substance does not dissolve in water, can be used in building materials and cement production of raw materials. This method is called limestone - gypsum flue gas desulfurization (FGD) chemical mechanism.
