In order to further promote the coordinated governance of pollution reduction and carbon reduction and promote the comprehensive green transformation of economic and social development, Weifang actively promotes the implementation of the task of "Weifang Pollution Reduction and Carbon Reduction Collaborative Innovation Implementation Plan", explores the technical methods and working paths of pollution reduction and carbon reduction synergy, and helps to build a better Weifang.
Qingzhou Zhonglian Cement Co., Ltd. is a listed company in the cement sector of China Building Materials Group under the supervision of SASAC, and a wholly-owned subsidiary of China United Cement, an important regional company of New Tianshan Cement . It is one of the most complete base enterprises in the new Tianshan cement industry chain and one of the typical representative enterprises practicing the "cement plus" development strategy. In order to strengthen energy and resource conservation and ecological environment protection, and enhance the ability of sustainable development, the company actively responds to the strategic objectives of national carbon peak and carbon neutrality. In recent years, it has implemented the green emission reduction demonstration projects of precise HSNCR denitrification system transformation, comprehensive utilization of solid waste, co-disposal of hazardous waste, carbon dioxide capture and purification in clinker production line, and has taken the lead in opening up new ideas of pollution reduction and carbon reduction in cement industry.
Leading the demonstration, creating a new model
of carbon capture technology, a new green emission reduction demonstration project with an annual output of 200000 tons of carbon dioxide capture and purification, and adopting the technology of cement kiln oxy-fuel combustion coupled with low-energy carbon capture, provide a new idea in the exploration of the synergistic path of pollution reduction and carbon reduction in the cement industry.
Intelligent and precise denitration to achieve ultra-low emission
in the industry For the transformation of ultra-low emission of nitrogen oxides in the new dry process cement clinker production line, a high-efficiency and precise denitration system HSNCR was built to optimize the out-of-stock system, further improve the denitration efficiency of cement kiln flue gas, and achieve more precise and efficient pollution reduction.
The company gives full play to the unique advantages of cement enterprises in the comprehensive utilization of resources, and uses solid wastes such as desulfurized gypsum, fly ash and steel slag as alternative raw materials for cement production, thus solving the problem of resource utilization of bulk industrial solid wastes. Through the recycling of solid waste, the synergistic effect of pollution reduction and carbon reduction is realized, and the dual benefits of environmental protection and economy are created. Co-disposal of
hazardous wastes, opening up a new path
for hazardous waste disposal The clinker production line is equipped with a cement kiln hazardous waste co-disposal production line, which has successfully disposed of about 96,900 tons of hazardous wastes since its operation, injecting a strong impetus into the optimization of the ecological environment in Weifang City and its surrounding areas. It strongly demonstrates the social responsibility of enterprises and the style of industry leadership. Through carbon dioxide capture, ultra-low emission transformation, comprehensive utilization of solid waste and co-disposal of hazardous waste
, Zhonglian Cement Co., Ltd. has helped to build a synergistic effect of pollution reduction and carbon reduction in cement and other industries. On the one hand, the implementation of the project has realized the reduction, recycling and energy treatment of pollutants. According to statistics, the carbon capture project has reduced carbon dioxide emissions by about 200,000 tons per year; the ultra-low emission transformation has reduced nitrogen oxide emissions by 218.7 tons per year; since the implementation of the solid waste utilization and treatment project, 64.08 tons per year of desulfurization gypsum and fly ash have been treated and recycled, and 28,800 tons per year of hazardous waste have been treated, reducing coal consumption by about 5,700 tons per year; Good environmental benefits have been achieved. On the other hand, it saves about 3.4 million yuan of coal annually, and increases the benefit of carbon dioxide products by 11.15 million yuan, which brings considerable economic benefits to enterprises.
On September 24, during the "14th China Cement Energy Conservation and Environmental Protection Technology Exchange Conference and the 6th Intelligent Summit Forum" hosted by China Cement Network, the participants visited the demonstration project of Qingzhou Zhonglian Cement Co., Ltd. with an annual output of 200,000 tons of carbon dioxide oxy-fuel combustion coupled carbon capture. (For details, please refer to the "14th China Cement Energy Conservation and Environmental Protection Technology Exchange Conference and the 6th Intelligent Summit Forum".
