"High energy consumption and serious pollution" is a traditional understanding of cement production enterprises. Nowadays, with the application of digital and intelligent technology, the production of cement building materials is another picture.
On April 12, in the park of Zongyang Conch Cement Co., Ltd., the clean factory roads and orderly production environment are eye-catching. In recent years, Zongyang Conch has accelerated the transformation and upgrading of traditional cement enterprises, and promoted the green development of enterprises by using environmental protection measures such as spraying dust, mine greening and tail gas purification. The Ministry of Industry and Information Technology recently announced the list of green manufacturing in 2023, and Zongyang Conch Cement Co., Ltd. was selected as the list of green factories.
In the dispatching room of Zongyang Conch Intelligent Mine, the real-time monitoring pictures of a series of mining operations such as shoveling and transportation on the limestone mine platform can be clearly seen through the large digital screen.
"Through real-time monitoring and intelligent analysis of digital mines, the dispatching center accurately and quickly feeds back the grade information of limestone, which maximizes the quality of ore mining." Zhu Jun, head of information technology of Zongyang Conch Company, said that in the past, mining, production and management mainly relied on people to command, and production data could not be fed back in real time, but now the digital intelligent mine system can monitor, analyze and make quick decisions in real time, and the mine car can carry out mining and transportation operations under the remote command of the system. But also ensures the quality of the ore, and the resource utilization rate reaches 100%. Since
2019, Zongyang Conch Digital Intelligent Mine System, Expert Automatic Operating System, Equipment Management and Auxiliary Inspection System, Intelligent Quality Control System and Energy Management System have been put into use one after another. The orderly promotion and operation of each system have realized the automation of plant operation, fault pre-control, visualization of management, coordination of all elements and intelligent decision-making, and further improved the quality of plant operation, economic benefits and safety and environmental protection level.
"We introduce modern technology to build a whole process intelligent factory." Cheng Xiaobing, general manager of Zongyang Conch, said that over the past 20 years since its establishment, Zongyang Conch has made one major breakthrough after another driven by innovation. Nowadays, through innovation and empowerment, enterprises use advanced technologies such as mobile communication network, data sensor monitoring, information interaction integration and adaptive control to realize the whole system intelligent optimization covering the whole cement production and delivery links, and build an advanced and reliable whole process cement intelligent chemical plant with conch characteristics.
In the central control room of Zongyang Conch Cement Co., Ltd., cement production is equipped with "industrial brain", through the kiln expert automatic operating system, as long as you click the mouse, you can see the actual situation of each process in the workshop on the computer. Accurately control the cylinder temperature and the minimum coal consumption of the clinker kiln, and effectively reduce the energy consumption in the cement production process. "Beautiful and clean factory area can not be separated from technical transformation and environmental protection management. In recent years, Zongyang Conch has implemented SCR denitrification project for all production lines, which has reduced the total annual emission of nitrogen oxides by more than 30%." Cheng Xiaobing said. Since the kiln expert automatic operating system was put on line, the comprehensive power consumption of conch cement clinker in Zongyang has decreased by 4.75 kWh, the standard coal consumption has decreased by 3 kg, and the machine failure rate has decreased significantly.
Integrate information resources and promote business management with data wisdom. Based on the intelligent platform, Zongyang Conch makes comprehensive use of various data and information to promote the development of all aspects of production and operation through intelligent management. In 2021, Zongyang Conch started the demonstration and construction of the pilot project of "Conch Industrial Brain", focusing on sorting out the existing pain points of information management, excavating the demands, combining with the actual production of the company, systematically sorting out the overall construction needs, and defining the direction of future cement industry brain and information project construction.
"Under the background of homogeneous product competition, realizing the diversification of enterprise industrial chain, reducing costs and improving efficiency has become the key to enhance the core competitiveness of cement enterprises." Cheng Xiaobing said that Zongyang Conch will take "accelerating the cultivation of world-class enterprises with global competitiveness" as the lead, take "factory intellectualization, management informatization, industry greening" as the direction, and combine with the actual construction needs of factory production, steadily promote the iterative upgrading of intelligent factories and the construction of unmanned and industrial brain projects, so as to achieve production and operation. To contribute positively to the high-quality economic and social development of Zongyang County.
