Today's science and technology board we comb together with Yuanchen Technology, the company is mainly engaged in the research and development, production, sales and service of filtration materials, flue gas purification series of environmental protection products. The company's main products are all kinds of high temperature and corrosion resistant filter bags and SCR denitrification catalysts, which are mainly used in industries and fields such as electric power, steel and coking, waste incineration, cement and glass, etc. The company's main customers are enterprises such as Longjing Environmental Protection, State Power Investment Group, Zhongdian Guorui, Fresh Environment, Shougang Jingtang, Anfeng Iron and Steel, China Resources Cement and Xinyi Glass.

The company's filter bag products are applied to industrial flue gas dust removal, bag type dust removal technology is currently one of the main dust removal technology applied in China, the working principle is that when the dust-containing gas passes through the filter bag, relying on the filter bag as a filter medium, through the role of sieving, inertia, adhesion, diffusion and electrostatic effects on dust capture, dust is blocked on the surface of the filter bag, clean gas is discharged through the gaps between the filter bag fibers, so as to achieve the separation of The clean gas is discharged through the gaps between the filter bag fibers, thus achieving the purpose of separating dust from dusty gas.

SCR denitrification catalysts are used in industrial flue gas denitrification. SCR denitrification technology is the most widely used technology in China, working on the principle of selective reduction of ammonia and nitrogen oxides to produce nitrogen and water under the action of denitrification catalysts, which plays a role in purifying flue gas and reducing nitrogen oxide emissions. The power industry took the lead in requiring NOx treatment, and the process of treatment gradually found that the wear life of the catalyst and coping with low load conditions became a problem; as the national control of pollution emissions from steel containing coking, glass, cement and other industries became stricter, the traditional vanadium and titanium catalysts also faced low efficiency, short life, single function and other problems in the new environmental protection island process route. The company has been attaching importance to technology research and development, and the core technologies independently developed, such as high-efficiency SCR denitrification technology for power plants, rare earth modified alkali-resistant SCR denitrification technology, medium and low temperature SCR denitrification technology, and NOx-dioxin synergistic removal technology, have successfully solved the above problems and have been successfully applied.

The company's SCR denitrification catalyst products are classified according to their application areas as power catalysts, sinter catalysts, glass kiln catalysts, cement catalysts, coking catalysts, lime kiln catalysts, waste incineration (denitrification/dioxin) catalysts, etc.


When the new crown epidemic occurred, the demand for protective equipment such as masks increased dramatically, especially the shortage of filtration materials such as upstream meltblown fabric. Leveraging its technical reserve and rich application experience in the filtration materials industry, the company started the research, development and manufacturing of PTFE laminated materials from 2013, and developed efficient and low resistance nano-level PTFE laminated materials that can replace meltblown cloth for masks in an efficient and timely manner using the existing technology base.

The environmental protection industry is divided into water pollution management, air pollution management, solid waste management and noise pollution management according to the service targets. Among them, air pollution management is one of the pillar industries in the environmental protection industry.

Atmospheric pollution is a phenomenon in which the concentration of pollutants in the atmosphere reaches such a harmful level that it destroys the ecosystem and the conditions for normal human survival and development, causing harm to people and things. Atmospheric pollutants include suspended matter and pollutant gases, suspended matter mainly includes TSP (total suspended particulate matter), PM10 (respirable particulate matter), PM2.5 (respirable particulate matter), and pollutant gases mainly include acid gases (sulfur dioxide SO2, nitrogen oxides NOX), greenhouse gases (carbon dioxide CO2, chlorofluorocarbons) and tropospheric ozone.

The main products produced by the company are various types of high temperature and corrosion resistant filter bags and SCR denitrification catalysts, which are specially used for the treatment of soot and NOx in industrial flue gas, and are an indispensable and important part of air pollution treatment, and have an important strategic position in the process of national air pollution prevention and control, whose market demand, technology level and the development and growth of the whole industry are closely related to the development of the environmental protection industry.
