In terms of technology research and development, Longjing Technology Center has developed a number of air pollution control technologies and equipment that fill domestic gaps and reach the international advanced level through a lot of experimental research and technology research and development. In the field of dust removal, Longjing is the first in the industry to independently develop a variety of high-efficiency dust removal technologies, such as wet electrostatic dust removal, low-temperature electrostatic dust removal, top-side combined vibration electrostatic dust removal, double-zone electrostatic dust removal, electric bag composite dust removal, bag dust removal, flue gas conditioning, high-frequency power supply, energy-saving control and so on. , making Longjing's dust removal technology the most comprehensive and product-rich in the industry. In the field of desulfurization, through the digestion, absorption and innovation of imported technologies, not only the key technologies for large-scale application of wet desulfurization of one million kilowatt units and dry desulfurization of circulating fluidized bed of 660,000 kilowatt units have been solved, but also the key technologies for wet desulfurization of carbide slag, recycling of desulfurization by-products, dry flue gas desulfurization in steel, garbage incineration, industrial kilns and other fields have been independently developed, as well as the localization technologies of large-scale pulse valves, lime digesters and other supporting equipment, and the flue gas desulfurization technology in China has also been mastered. In the field of denitrification, Longjing not only mastered the design ability of selective catalytic reduction (SCR) and selective non-catalytic reduction (SNCR) denitrification equipment, but also independently developed the catalytic oxidation absorption (COA) denitrification technology with independent intellectual property rights. In view of the strong demand of national PM2.5 and multi-pollutant control in the future, Longjing Technology Center is cooperating with the Particle System Simulation Center of the University of New South Wales in Australia to carry out numerical simulation research on gas flow and gas-solid two-phase flow in industrial flue gas purification devices, cooperating with the Energy and Environment Research Center (EERC) in the United States to develop embedded electric bag (AHPC) technology, cooperating with Tsinghua University and others to develop large-scale wet electrostatic precipitator technology in coal-fired power plants, and cooperating with North China Electric Power University to develop cooperative control technology for dry desulfurization of multi-pollutants.
