A few days ago, the China Electricity Council (hereinafter referred to as CEC) completed the statistical work on the 2011 flue gas desulphurization, denitrification and thermal power plant flue gas desulphurization franchise-related information. Among them, the first place is Beijing Guodian Longyuan Environmental Protection Engineering Co., Ltd. with an operating capacity of 14030MW. Followed by China Power Investment Yuanda Environmental Protection Engineering Co., Ltd. and China Huadian Engineering (Group) Co., Ltd., ranked second and third. Among them, the limestone-gypsum wet method is the main method used for desulfurization. It will also lay the foundation for controlling the emission of sulfur dioxide in the future in the increasingly deteriorating atmospheric environment.
China has conducted a variety of research and application of desulfurization technology. Each thermal power plant is put into the flue gas desulfurization system and controls the emission of sulfur oxides through flue gas desulfurization technology. The prevention of sulfur dioxide in thermal power companies has become a top priority for environmental protection agencies. The environmental protection agencies are actively seeking for supporting the construction of funds for desulphurization and denitrification equipment for these enterprises, and they also actively invite experts from domestic and foreign desulphurization technology centers to provide desulfurization and denitrification technology support for the national thermal power enterprises, and regard the desulphurization of power plants as an important task to complete. Limestone desulphurization is the main process for flue gas desulphurization in power plants in China. Limestone used as a limestone (lime)-gypsum wet desulfurization process absorbent is widely distributed in China and has abundant resources. Limestone grades are also good in many areas, and the calcium carbonate content is 90. %the above. Excellent people can reach more than 95%. Among the various absorbents in the desulfurization process, limestone is inexpensive, and after the crusher and Raymond mill, calcium utilization rate is high, and there are many manufacturers can provide finished limestone powder. The use of calcium carbide slag as an absorbent can be abolished.
Limestone (lime) - gypsum wet desulfurization process desulfurization rate of up to 95%, after the desulfurization of the flue gas is not only low concentrations of sulfur dioxide, and the dust content of flue gas is also greatly reduced, large units using wet desulfurization process, sulfur dioxide removal A large quantity is conducive to the actual total control of regions and power plants. The use of desulfurization technology can effectively solve environmental problems. Most power plants use Raymond Mills to process limestone fines to improve desulfurization efficiency. According to the requirements of the State Environmental Protection Administration, thermal power companies must build supporting desulfurization and denitrification devices. However, the desulfurization equipment built up now has a very big problem. Because the vicious competition in the market leads to low equipment quality, the commissioning rate of the desulfurization equipment is less than 60%, but the huge investment does not bring about the reduction of atmospheric pollutants. The major thermal power plants also pay more and more attention to desulfurization systems. In the desulfurization system, desulfurization needs to increase the use of Raymond Mill to process limestone powder and prepare active limestone slurry.
