Description

Technical Field

[0001] The utility model relates to the technical field of chemical raw material processing equipment, in particular to a reflux device for organic chemical raw materials. Background Technique

[0002] In the process of organic chemical reactions, reactants usually need to react under high-temperature conditions, and a large amount of steam will be generated during these reaction processes. If these vapors cannot be effectively recycled, it will lead to problems such as reduced reaction efficiency and waste of resources. Although the reflux devices in the related technologies can improve the reflux efficiency to a certain extent, under high-temperature and high-pressure conditions, the steam cannot be fully condensed in the condensation device, resulting in insufficient condensate volume and low reflux efficiency. The reflux of the condensate depends on gravity and is easily affected by internal pressure changes, so the reflux process is not stable enough, affecting the continuity and stability of the reaction. It is impossible to monitor and control the flow rate and quantity of the reflux liquid in real time, resulting in low control accuracy of the reflux process and difficulty in adapting to the needs of different reaction conditions. In view of this, it is necessary to improve the current reflux device to solve the above problems;
