The first SCR denitration project constructed by Conch Group in Jining Conch was put into trial operation, which achieved a significant reduction in nitrogen oxide emissions and explored a new way for ultra-low emissions in the cement industry.
This is another major environmental protection demonstration project created by Conch Group after building the first carbon dioxide capture and purification project in the cement industry. It will congratulate the 70th anniversary of the founding of New China with the positive actions to implement the new development concept and protect the clear water and blue sky.
Jining Conch is one of the most prominent subsidiaries of Conch Group in environmental protection. Since this year, Jining Conch ’s dust and nitrogen oxide emission indicators can be controlled below 10 mg / m³ and 100 mg / m³, respectively, far better than the national standards.
The SCR denitration project is an advanced environmental protection and emission reduction project cooperated by Conch Group and well-known foreign companies. It is also a 2019 national air pollution comprehensive prevention and control central reserve application project and a key environmental protection project supported by the local government. SCR flue gas denitrification technology has a few application precedents in Europe and the United States. It mainly uses catalysts to convert NOx in the flue gas of cement kiln to nitrogen and water at a certain temperature, thereby reducing the emission of nitrogen oxides.
This project was launched a year ago, and encountered many technical difficulties during the construction process. After joint research and exploration of Jining Conch, Conch Design Institute and related foreign technical experts, a series of difficulties were solved, and finally all the commissioning was successfully completed. Test run.
According to the analysis of the results of the recent trial operation, the nitrogen oxide emission index can be controlled below 90mg / m³, and ammonia slip is superior to the national standard. Compared with the national standard, the annual emission of nitrogen oxides can be reduced by more than 600 tons.
Jining Conch has always insisted on creating green benefits and contributing green power to Jining City. At the beginning of the construction of the plant, a set of 9MW waste heat power generation system and a set of 1.5MW wind turbine were built. In the past two years, Jining Conch has actively promoted mature waste incineration power generation, solid waste treatment, photovoltaic power generation and other projects to further enhance its own environmental protection strength and support local environmental protection. According to statistics, Jining Conch Waste Heat Power Generation, Wind Power Generation, Waste Incineration Power Generation, Photovoltaic power generation and other projects can generate more than 100 million kilowatt-hours throughout the year, and they are constantly approaching the production of "zero-use electricity", bringing a double harvest of economic and environmental benefits.
