Technical Field

[0001] This application relates to the technical field of rectification column reflux drums, and particularly relates to a control device for a rectification column reflux drum. Background Art

[0002] The rectification column reflux drum is an important device in the rectification process, used to assist in controlling the reflux ratio in the rectification column and stable operation. The rectification column reflux drum is widely used in the rectification processes in fields such as petrochemical industry, chemical industry, pharmaceutical industry, and food industry. In petroleum refining, it is used to separate and purify petroleum products. In chemical production, it is used to extract chemicals with higher purity. In the pharmaceutical and food industries, it is used to extract and separate active ingredients and raw materials.

[0003] The operation of the rectification column reflux drum needs to pay attention to the accuracy of controlling the reflux ratio to ensure the required separation effect and yield during the rectification process. Monitoring the liquid level, pressure, and temperature inside the drum is crucial to ensure the stability and quality of the reflux liquid and avoid fluctuations or unstable factors during operation from affecting the operation of the rectification column. Currently, when the existing reflux drum is in use, it is not convenient to monitor the reflux drum. When abnormalities occur in the internal environment of the drum, timely adjustment cannot be obtained, which easily affects the operation of the rectification column. For this reason, we propose a control device for a rectification column reflux drum. Summary of the Utility Model
