Humidity, temperature, wind speed, wind direction, PM2.5, PM10, TSP, air pressure.. Walking into the construction site of the digital intelligent green factory technology transformation project of Witton Cement Group Co., Ltd., we can see the above indicators displayed by the environmental on-line monitoring system in real time. The real-time collection of
these environmental indicators is only the "tip of the iceberg" for Witton Cement to implement digital, intelligent and green technological transformation and comprehensively promote the high-quality transformation and development of enterprises.
In recent years, Witton Cement has adhered to technological innovation and green development, taking cement manufacturing as the main industry, extending the industrial chain, developing related diversified industries, including concrete, hazardous waste disposal, transportation logistics, building materials admixtures, environmental sanitation management and other industries, and is the backbone enterprise and special cement production base of Shanxi building materials industry.
This digital and intelligent green factory technology transformation project , which started in March 2022, has a total investment of 1.05 billion yuan. Through capacity replacement, a second-generation new dry process cement clinker production line with a daily output of 4500 tons (including 50000 tons of hazardous waste and 400 tons of domestic waste) will be built in the original site, and a special cement clinker production line with a daily output of 1500 tons will be renovated. The whole plant is transformed into a digital, intelligent and green plant.
The factory area is too big, the reporter stood on the ground, raised his head to the limit, looked at the blue pipes, red steel plates and white pipes above, and could not help wondering: "What does our project include?"
"This week is all, Daxin is newly built, and a small part is rebuilt, basically on the basis of the original plant, the original production line will be discontinued after the project is put into operation, which is equivalent to building a new Witton cement." Jiang Heguo, general manager of Witton Cement, drew a circle with his finger.
In recent years, Witton Cement has actively implemented the strategy of innovation-driven development, vigorously promoted technological innovation and technological research and development, successively established provincial enterprise technology centers, provincial technological innovation centers and municipal key laboratories, developed and produced a number of varieties of special cement, with 37 technical patents, and has established a number of enterprises. It has been appraised as a provincial intelligent manufacturing demonstration enterprise, a high-tech enterprise and a green factory.
The implementation of the digital intelligent green factory technology transformation project is an important milestone in determining the future development of Witton Cement-the
construction of intelligent feeding control system:
all kinds of raw materials are sent to the joint storage for storage, and two fully automatic stackers are used for stacking. The storage yard is provided with three intelligent grab buckets for material taking, and the intelligent grab buckets realize automatic material taking, material dumping and material feeding through the three-dimensional scanning three-dimensional imaging technology and the automatic control system, and the whole process does not need manual intervention to realize intellectualization and full automation;
Construction of green clinker burning system:
the adoption of high energy efficiency six-stage preheating and pre-decomposition technology, low nitrogen combustion technology and material bed grinding technology can reduce unit pollutant emissions by 50% and energy consumption by 15%; Intelligent factory
construction:
starting from intelligent planning, covering intelligent control, intelligent management, intelligent logistics, intelligent analysis and intelligent service, to realize intelligent manufacturing of cement industry;
Construction of green intelligent mine:
through digital mining software system platform, mine production execution system platform, mine visual management and control system platform and other digital systems, promote more scientific mine production management, and give full play to the efficiency of personnel and equipment; After the completion of the
project, the comprehensive energy consumption, power consumption, coal consumption and other indicators of the unit product of Witton cement clinker can reach the first-level energy consumption indicators of the Energy Consumption Quota of Cement Unit Product. It can save 17000 tons of standard coal annually, reduce 46000 tons of carbon dioxide emissions, and meet the requirements of ultra-low emission indicators of Shanxi cement industry.
Today, the raw material storage and transportation system, raw material grinding system, firing system, clinker storage and transportation system of the project have been installed and are being debugged. The special cement clinker production line project with a daily output of 1500 tons has completed civil construction and equipment installation is under way.
All the projects have entered the final stage, which makes the whole project site seem a little quiet. Only the sound of electric welding from high in the sky from time to time, as well as a few dull knocks, made people feel the amazing energy that the giant, which was dormant in the middle of winter, inadvertently leaked out.
The company fully implements the new development concept, takes the construction of green, low-carbon and environmentally friendly modern cement manufacturing enterprises as the development direction, adheres to technological innovation and green development, realizes digital empowerment and intelligent manufacturing, and focuses on the construction of intelligent green factories, mainly starting from intelligent planning. It covers intelligent control, intelligent management, intelligent logistics, intelligent analysis and intelligent service, and realizes the intelligent manufacturing of cement industry.
