Description

Technical Field

[0001] The invention relates to the technical field of petroleum coke blending, and in particular to an automatic control and regulation system for petroleum coke blending. Background Art

[0002] In the production and application of petroleum coke, blending is a crucial link. The traditional petroleum coke blending process mainly relies on manual operation, which is not only inefficient, but also difficult to ensure the accuracy of the blending ratio and the uniformity of the blending. In addition, due to the limitations of manual operation, there are certain hidden dangers in the stability and safety of the system. First, the traditional blending method has a large error in controlling the blending ratio. In the process of manual weighing, calculation and mixing of petroleum coke raw materials, it is easy to be affected by human factors such as fatigue and distraction, resulting in inaccurate blending ratios, which in turn affects the quality of petroleum coke. Secondly, the mixing effect of the traditional blending method is not ideal. Due to the limitations of manual stirring, the mixing of petroleum coke raw materials is often not uniform, and there are local concentrations that are too high or too low, which will affect the overall performance and use effect of petroleum coke. Moreover, the stability and safety of the traditional blending system need to be improved. Due to the lack of automated monitoring and alarm mechanisms, once the system is abnormal or fails, it is often difficult to detect and handle it in time, which brings safety hazards to production. In addition, the traditional blending system is also insufficient in energy consumption management and maintenance efficiency. The lack of real-time monitoring and analysis of energy consumption data leads to high energy costs; unsystematic maintenance records and unreasonable maintenance plans lead to low maintenance efficiency and high maintenance costs.
