Asia Cement Corporation sets a good example with green smart factory

        Novel coronavirus pneumonia broke out in 2020, the global economy was hit, and China's cement industry was also affected. Fortunately, the resumption of production, the policies of keeping employment, the financial sector, foreign trade, foreign and domestic investments, and expectations stable and other measures such as producing at staggered hours, energy saving and consumption reduction, and integration of industrial chain, the management environment was gradually improved. However, the far-reaching impact of the epidemic has also brought a new wave of challenges for the industry. This article will introduce how Asia Cement Corporation (China) takes intelligent production as the core and intelligent management as the guarantee to set up a green and intelligent production line in the new era!

        Asia Cement Corporation (China) has five types of enterprises in mainland China, namely, consistent cement manufacturing plant, grinding plant, cement products plant, transportation company and investment company. It has formed a strict and efficient production, transportation and marketing network, and its operation bases are all over Jiangxi, Sichuan, Hubei, Jiangsu and Shanghai.

        China has been threatened by novel coronavirus pneumonia. With the opening of vaccination in China, the epidemic situation is expected to be under control. With the government's "14th Five-Year plan" "new infrastructure and new urbanization initiatives and major projects", the national comprehensive transport network, the Yangtze River economic belt and the rise of central China, and the more stringent constraint standards and enforcement efforts of the supply side, in the long run, cement demand is stable. However, with the intensification of the epidemic, the networked and intelligent production and marketing mode has become a trend, and how to accelerate carbon neutralization is also a major issue. The only way to cope with this problem is to transform the production line by combining green intelligent technology.

        Internet + big data to build smart factory

        Look at the situation, the Ministry of industry and information technology and the Ministry of emergency management of PRC promulgated the "industrial Internet + safe production" plan (2021-2023) in 2020, urging enterprises to build a rapid perception, monitoring, early warning, disposal and evaluation system, expand the application of industrial Internet, so as to improve the digital, networked and intelligent level of production and realize safe production management.

        Following the policy guidance, Asia Cement Corporation (China) uses advanced technology and superior equipment to build smart chemical plants from smart mines, smart quality control, smart production, smart energy, smart inspection, smart industrial safety and smart logistics.

        In order to control the production process and quality of clinker and cement in real time, optimize the operation parameters of the control system, ensure the best effect of energy conservation and emission reduction, and improve the output and quality, Asia Cement Corporation (China) has successively established the automatic sampling, detection and analysis system of raw materials and fuels, as well as the automatic control operation system of clinker and cement production line, the automatic batching system of raw material, automatic bagging system for bagged cement, automatic loading system for clinker and cement, etc. In addition, the intelligent mine management system established by Jiangxi Yadong cement and Huanggang Yadong cement is equipped with four sets of modules, including real-time 3D visualization system, information input system, remote integrated supervision system and Internet of things (IOT) data receiving center, which can display mine production information in an all-round way and facilitate mine managers to monitor real-time image, production, vehicle positioning, cross-border warning, cross-border records of the mine and other data, which are used to conduct remote command for important links such as mining, processing, production and green restoration, so as to improve the efficiency of decision-making.

        In order to effectively improve the operation efficiency and safety production capacity, Asia Cement Corporation (China) is also actively building intelligent diagnosis and early warning system for production equipment, intelligent power transmission and intelligent delivery system, and stepping up the construction of intelligent mining system, intelligent energy management system, intelligent safety monitoring system for personnel and equipment, automatic cement delivery system, automatic laboratory, automatic unloading system. At the same time, the automatic sampling, sample preparation and testing system of raw and fuel will be further improved and the intelligent inspection system of production line will be developed, so as to reduce the risk of personnel inspection work and reduce equipment operation failure, moving towards the goal of large-scale intelligent cement plant.

        Scientific carbon reduction + turning waste into treasure to carry out recycled economy

        Cement industry is an important pillar of national economic development, but it has been regarded as a high energy consumption and high pollution industry. In order to implement the belief that "industrial development goes hand in hand with environmental protection", Asia Cement Corporation (China) has adopted advanced production technology and equipment since its establishment. It adheres to the highest environmental protection standards and high-efficiency manufacturing processes, and adheres to manufacturing high-quality products. Not only its energy consumption and environmental emission indicators are superior to national and local standards, with the social development and technological progress, the plants also continue to make progress towards carbon peak and carbon neutralization technology, including: grinding construction waste, limestone, coal-fired slag into composite powder, reducing the proportion of clinker in cement, and producing low-carbon cement; It is estimated that the energy consumption and power consumption per unit product will be reduced by 0.5% every year, and the target will be completed within 3 years; Increase the proportion of alternative fuels (such as waste derived fuels, biomass fuels, waste tires, etc.) used in cement kilns, reduce the consumption of fossil fuel are expected to reach 5% by 2025; Using carbide slag, fly ash, sulfuric acid slag and other industrial wastes to replace some raw materials can not only reduce the amount of mining, but also reduce the emission of carbon dioxide; It is expected that by the end of 2022, all production lines will reach class B emission standard, and reach class A emission standard by 2025 to further reduce pollutant emissions; Green mines, green factories and green supply chain will be widely established to achieve carbon sink and reduce the concentration of greenhouse gases in the atmosphere. It is expected to complete the national green mines and green factories certification in 2023. Moreover, in the future, Asia Cement Corporation (China) will actively evaluate the feasibility of carbon capture and recycling technology in factories, and explore the investment in solar power generation, hoping to become the preferred partner for building a sustainable green home.

        In addition to carbon reduction by science and technology, Asia Cement Corporation (China) also uses the high temperature characteristics of cement kilns to help the government solve various pollutant treatment problems while producing cement. The disposal project has gradually expanded from urban domestic waste at the beginning to metal contaminated soil, industrial hazardous waste, medical waste and other categories. For example, Jiangxi Yadong cement assisted in the treatment of general industrial waste and construction waste; Sichuan Lanfeng cement cooperated with the government to treat municipal sludge; Besides municipal sludge, Hubei Yadong cement also supports the treatment of contaminated limestone powder; Sichuan Yadong cement also deals with drilling cuttings, waste refrigerator insulation materials, etc. In the future, factories such as Jiangxi Yadong cement, Sichuan Yadong cement and Sichuan Lanfeng cement will further plan hazardous waste treatment, and Hubei Yadong cement will also be put into the field of heavy metal contaminated soil treatment. In this way, it can not only clean up the urban waste, improve the utilization rate of industrial waste residue, reduce the consumption of fossil fuel in cement kiln, but also significantly reduce the emissions of waste water, waste residue, waste gas and carbon dioxide.

        Safety, environmental protection, quality and efficiency have always been the focus of Asia Cement Corporation (China). Therefore, on the one hand, all production units expand Internet applications and build digital mines to realize intelligent and safe production through operation automation, management visualization and fault pre control; On the other hand, it also increases the investment in environmental protection and accelerates the layout of green development, so as to create a leading green enterprise model with consistent and efficient energy saving and intelligence, and continue to expand the influence and power in the new round of industry merger and reorganization
