On March 30, the announcement of the award-winning project of the 2022 China Building Materials Federation and China Silicate Society Building Materials Science and Technology Award was issued. Li Yeqing, president of Huaxin Cement Co., Ltd., as the first person to complete the project of "Innovation and Application of Key Technologies for Intelligent Low Carbon Manufacturing of Cement", won the first prize in the category of technological progress. Li Yeqing led the company's innovation team to win the industry award again after the project "Development and Application of Low Carbon and Nitrogen Reduction Super Large-scale Cement Production Technology and Equipment" won the first prize in 2021.
It is reported that the Building Materials Science and Technology Award is a comprehensive and authoritative science and technology award for the national building materials industry, and is an important basis and way for the building materials industry to nominate national science and technology awards. A total of 67 projects were awarded the 2022 Building Materials Science and Technology Award, which was approved by the Leading Group of the Building Materials Science and Technology Award composed of the China Building Materials Federation and the China Silicate Society. Aiming at the "carbon peak and carbon neutralization" in the cement industry, the project of
"Innovation and Application of Key Technologies for Intelligent Low Carbon Manufacturing of Cement" has put forward and constructed an industrial intelligent system of key technologies for intelligent low carbon manufacturing of cement with completely independent intellectual property rights, and has made many achievements in technological innovation. Firstly, a fully localized advanced control system for low-carbon cement manufacturing has been developed, which solves the technical problem of unstable production caused by large-scale use of RDF, ensures the stable operation of cement production process, and significantly reduces coal consumption and carbon emissions. The second is to take the lead in developing an intelligent joint storage material handling system based on driverless driving technology, which realizes the precise and diverse collocation of complex raw materials and fuels, and lays a foundation for the stable operation of cement production. Thirdly, a cement intelligent online quality control system driven by quality data has been developed, which solves the problem that the quality of raw materials and fuels is difficult to guarantee when the quality of raw materials and fuels fluctuates greatly, and realizes the high-quality and low-carbon production of cement. Fourthly, an intelligent equipment monitoring and optimization system for comprehensive monitoring of production equipment and safety is constructed, which realizes the functions of real-time monitoring, fault prediction and intelligent early warning of cement production equipment, improves the operation rate of equipment and ensures the safe operation of production. The project has authorized 8 invention patents, 9 software copyrights and published 8 papers. The promotion and application of the results of this
project has important demonstration significance for promoting the integration of two modernizations and the green, low-carbon and high-quality development of China's building materials industry. As of December 2022, the results of the project have been popularized and applied in 18 cement production lines in Hubei, Hunan, Yunnan, Tibet and Sichuan, and have achieved outstanding economic and social benefits. In terms of economic benefits, the industrial intelligent system that has been put into operation has accumulated about 157 million yuan, and Huaxin's comprehensive promotion is expected to produce a huge economic benefit of about 554 million yuan per year. In terms of social benefits, about 99500 tons of coal have been saved, 47.04 million kilowatt-hours of electricity have been saved, and about 365400 tons of carbon emissions have been reduced. After comprehensive promotion, carbon emission reduction can reach 664000 tons per year, and the effect of energy saving and carbon reduction is remarkable. In the context of the sharp decline in profits in the
cement industry, promoting green, intelligent transformation and energy saving and consumption reduction has become the key to the survival of cement enterprises. In order to further promote the green, digital and intelligent development of the cement industry, China Cement Network will be launched on April 24-25, 2023. The "China Cement Industry Green Development Summit Forum and Ultra-clean Emission Technology Exchange Conference" and the "Fourth China Cement Intelligent Summit Forum" were held in Changsha, Hunan Province, inviting industry experts, cement and related enterprises. Jointly promote the high-quality development of the cement industry!
