[0002] Energy analysis is an energy management method, which is of great significance for improving the scientific management level of national or enterprise energy and energy conservation and consumption reduction work. The traditional energy analysis method adopts the "black box" method, that is, the energy consumption system of a country or enterprise is regarded as a system with a determined boundary, and only the balance relationship between the energy income and expenditure of the system is studied, and the form of expression is an energy flow diagram.

[0003] The traditional energy analysis method based on the national (regional) energy flow diagram and the enterprise production energy flow diagram takes the distribution, conversion, and consumption processes of various energy sources as the main line, reflecting the quantitative balance relationship of enterprises in aspects such as energy income storage, processing conversion, transportation distribution, and use and external sales (end use). Different types of enterprises can draw the same type of energy flow diagram, reflecting the commonality of general enterprises.

[0004] The essence of enterprise production is the orderly movement of material flow driven and affected by energy flow. The process flow is complex and diverse, and different processes have different production processes and components. Analyzing energy utilization and composition, energy efficiency and loss conditions outside the process flow ignores the energy balance relationship between each energy-using link and unit within the system, and lacks guidance for production condition adjustment, energy control, and process optimization.

[0005] In view of the technical problem of low energy control efficiency in the related art, no effective solution has been proposed yet. Summary of the Invention

The legend indicates the materials and equipment represented by different graphics and colored lines in the drawing area (if the equipment has been described in the drawing area, it is not repeated). Figure 3 Among them, the red line in the drawing area represents the flow direction of crude oil, the yellow line represents the flow direction of natural gas, the green line represents the flow direction of water, and the blue line represents the flow direction of electricity.

[0041] Figure 3Clearly shows the flow directions, energy consumption and energy distribution of oil, gas and water in the thin oil treatment station. The energy statistics table centrally reflects the energy situation of the entire system. The energy utilization rate of the treatment station is 68.14%, which is lower than the index requirement. Through the process analysis of the energy flow diagram, 3 uneconomical process links are determined, namely the low efficiency of the lift pump before the heating furnace, the unused waste heat of the heating furnace flue gas, and the large heat dissipation loss of the oil tank. It is proposed to improve the efficiency of the lift pump equipment, recover and utilize the waste heat of the heating furnace flue gas, and transform the thermal insulation of the storage tank.

[0043] The above is only an example, and this embodiment does not make any specific limitations.

[0044] Through this embodiment, by obtaining the target process flow, the energy balance relationship between multiple energy-consuming links is determined based on the target process flow. Among them, the target process flow consists of multiple energy-consuming links and the connection relationships between multiple energy-consuming links. The energy balance relationship is used to represent the relationship between the energy flow parameters of multiple energy-consuming links. An energy flow diagram is generated according to the energy balance relationship. Among them, the energy flow diagram is used to represent the energy flow state of the production system. The production system uses the target process flow to carry out production work according to the energy flow state. Since the energy flow diagram is generated according to the process flow of the production system, the energy flow diagram is associated with the production process, and the specific energy flow state can be clearly and completely known to the staff. Therefore, the technical problem of low energy management and control efficiency existing in the related technology can be solved, and the technical effect of improving the energy management and control efficiency can be achieved.

Then the difference between the above - mentioned first output energy and the above - mentioned second input energy is - 21.49WJ, and the above - mentioned predetermined threshold can be configured as ± 10WJ. When - 21.49WJ exceeds ± 10WJ, it is determined that there is energy imbalance between the 2x3000m 3 first - stage settling tank and the 2x500m 3 buffer tank, and there is a situation of excessive energy loss.
