In order to control the deteriorating atmospheric environment, it is imperative to control the emission of sulfur dioxide. China has carried out research and application of various desulfurization technologies. Each thermal power plant is put into a flue gas desulfurization system to control the emission of sulfur oxides through flue gas desulfurization technology. The prevention and control of sulfur dioxide in thermal power enterprises has become the top priority of the environmental protection departments. While actively pursuing the funds for the construction of desulfurization and denitrification equipment for these enterprises, the environmental protection department also invited experts from domestic and foreign countries and national desulfurization technology centers to provide desulfurization and denitration technology support for national thermal power enterprises, and desulfurization of power plants as an important task. Limestone desulfurization is the main process of flue gas desulfurization in power plants in China. As a limestone (lime) gypsum wet desulfurization process absorbent limestone, it is widely distributed in China and rich in resources. The limestone grade in many areas is also very good. The calcium carbonate content is above 90%. Excellent users can reach more than 95%. Among the various absorbents in the desulfurization process, limestone is inexpensive, and after the crusher and Raymond mill, the calcium utilization rate is high, and many manufacturers can provide finished limestone powder. The use of calcium carbide slag as an absorbent can be used to treat waste.

The desulfurization rate of limestone (lime) gypsum wet desulfurization process is as high as 95%. The flue gas after desulfurization is not only low in sulfur dioxide concentration, but also the dust content of flue gas is greatly reduced. The large unit adopts wet desulfurization process and the sulfur dioxide removal amount is large. It is beneficial to the actual total control of the area and the power plant. The use of desulfurization technology can effectively solve environmental problems. Most power plants use Raymond mill to process limestone fine powder to improve desulfurization efficiency. According to the requirements of the State Environmental Protection Administration, thermal power enterprises must build supporting desulfurization and denitration devices. However, the desulfurization device built now has a very big problem. Due to the vicious competition in the market, the quality of the equipment is low, so the commissioning rate of the desulfurization device is less than 60%, and the huge investment does not bring about the decline of atmospheric pollutants. All major thermal power plants are paying more and more attention to the desulfurization system. How to choose the appropriate desulfurization process and desulfurization equipment has become the primary concern of power plant equipment purchasers. In order to assist the normal operation of the desulfurization system, and the limestone slurry in the absorption tower should be periodically replaced to maintain the activity, it is necessary to increase the desulfurization with a Raymond mill to process the limestone powder to prepare the active limestone slurry.

At present, the proportion of self-desulfurization technology in China has been significantly improved. Some large-scale desulfurization equipment production companies have emerged, and domestic production technology has been relatively mature. Veken Heavy Industry is a professional large-scale industrial mill manufacturer, producing and selling various types of mill equipment. It is especially suitable for large-capacity crushing and milling of limestone and white ash. In the desulfurization and milling process of steel plants and thermal power plants, the desulfurization rate is over 92%, and the use and maintenance are convenient and the effect is remarkable. The 7r large-scale high-pressure medium-speed mill produced by Veken Heavy Industry produces large-scale production. After starting work, the grinding roller rotates around the main shaft, and under the action of high-pressure spring and centrifugal force, it is close to the grinding ring, and its rolling pressure is equal to the dynamic condition. The ordinary Raymond powder machine is 1.2 times higher and the output is greatly improved. It is well matched with the normal operation of the desulfurization system of the power plant and fully meets the needs of large thermal power plants.
