municipal solid waste incineration is classified as hazardous waste because it contains a variety of harmful substances, and fly ash treatment has gradually become an urgent problem to be solved in municipal solid waste treatment. The co-processing of MSWI fly ash in
cement kiln is one of the important treatment methods at present. Adding fly ash as raw material to the cement production process can replace part of the cement raw materials, effectively remove the harmful substances in fly ash, and realize the resource disposal of fly ash.
In recent years, Jurongtai Cement has successfully realized the efficient co-disposal of domestic waste incineration fly ash and other general solid wastes in cement kilns by virtue of its advanced "zero discharge of waste water from washing and dechlorination of waste incineration fly ash and salt separation (FWD) technology".
The project started construction in December 2019 and was put into operation in October 2021, focusing on overcoming the problem of fly ash disposal in waste incineration plants, with an annual disposal capacity of up to 50000 tons, which significantly reduced the emission of fly ash after its operation, ensured the harmless and resource utilization of the treatment process, and made the disposal of fly ash more effective. It has contributed an important force to the construction of Zhenjiang's "waste-free city" and "sponge city".
As a national green factory, Jurong Taini Cement has made bold explorations in new equipment, new technology and new technology in recent years, and has invested more than 800 million yuan to complete the technical transformation of production line, such as energy saving and consumption reduction, environmental protection and ultra-low emission, clean energy transportation, and co-disposal of fly ash in cement kilns. The energy consumption level has reached the provincial benchmark level, the energy consumption has been reduced by 10% compared with that before the technical transformation, and the output value has increased by more than 20%.
China Cement Network will hold the " 11th China Cement Energy Conservation and Environmental Protection Technology Exchange Conference-Equipment Renewal Forum " in Nanjing, Jiangsu Province on June 13-14. This forum will gather government leaders, industry technical specialist, scientific research institutions, universities, cement enterprises and equipment suppliers to discuss and analyze the practical path of equipment renewal and green upgrading in the cement industry, so as to promote the industry to move towards a more energy-efficient, greener and environmentally friendly future. After the meeting, we will also organize a visit to Jurong Taini Cement Co., Ltd., a national green factory and a national green mine.
