Digitization Helps Cement Factories to Manage and Control Smart Energy Consumption
The cement industry is a traditional high-energy-consuming industry. Cumbersome equipment and extensive management used to be the labels of cement enterprises. Today, in the environment of energy saving, emission reduction and green production, how to achieve efficient management of enterprise energy is extremely important.
The cement production process consumes a lot of energy. According to the traditional energy management method in the past, once the abnormal energy consumption data is found, the staff must analyze from the complicated data what link, what time, and what equipment wastes energy. Not only is it time-consuming and labor-intensive, but it is also difficult to find the key to the energy management problem and the solution to the problem. Through the introduction of an energy management visualization system based on multi-point monitoring and cloud computing data analysis, the online collection, transmission and analysis of energy data can be realized, which has played a role in ensuring the downward shift of the focus of daily energy management and control.
Using the energy management visualization system, just log in to the energy management and control center on the computer. The power consumption and coal consumption of workshops, processes, procedures, teams, etc. are clear at a glance. It can clearly see the energy consumption of each device every minute, and accurately grasp the trend of energy consumption. And find out the unreasonable and unscientific operation of the equipment, excavate the energy saving space, realize long-term sustainable energy saving, truly achieve energy saving and consumption reduction, and technology first.
The overall energy management of the cement plant adopts a process-based intelligent manufacturing model. It takes the energy management system as the central platform, and collects the information of all process production units, energy process system information, abnormality and fault information. It implements centralized and flat dynamic monitoring and digital management of the production, transmission and distribution and consumption links of the enterprise energy system, improves and optimizes the energy balance, and realizes the integration of management and control of systematic energy conservation and consumption reduction.
The energy management system applicable to cement plants includes four platforms: real-time monitoring, abnormal alarm, energy management, and energy efficiency analysis. Real-time monitoring and scheduling can view the equipment operation status and process data of each production and energy process system in real time. The abnormal alarm can detect abnormal energy consumption in time. Just click on the abnormal data to accurately locate the point of energy waste and trace the cause of abnormal energy consumption accurately and efficiently. Energy management can realize the statistics, analysis, benchmarking, and evaluation of production line energy consumption data, and provide a basis for enterprise energy management. Energy efficiency analysis can analyze and calculate the energy saving space and energy saving of equipment, analyze the energy consumption data collected in the production process, and further optimize the process and reduce energy consumption. For example, through the analysis of economic electricity consumption for avoiding peaks, the accurate actual electricity price of each process every day is calculated, and the target electricity price is set on this basis, and each workshop, department, and operator is encouraged to reasonably organize off-peak production, and use as little electricity as possible during peak hours. It is also possible to pay electricity bills by calculating the maximum demand electricity consumption to reduce electricity costs,
Today, relying on the dramatization and networking of the energy management system, real-time monitoring of equipment operating status without blind spots and full parameters can be realized. It can also quickly find energy consumption and energy waste problems, improve energy efficiency and energy saving and efficiency, and make enterprise energy management more intelligent.
