Product Overview
The stainless steel gap distillation experimental device mainly consists of important parts such as tower kettle, distillation tower, condenser, reflux ratio, tower top receiving tank, vacuum system, control system, etc. The system has atmospheric pressure, reduced pressure, and pressurized gap distillation operations, and can also be used for reactive distillation experiments. After the reaction is completed, distillation separation experiments can be carried out. The design pressure needs to be based on the customer's process requirements. During the pressurization operation, it is necessary to consider the equipment's pressure resistance and voltage stabilization control. In the depressurization experiment, manual vacuum degree adjustment is achieved through the micro pressure regulating valve on the vacuum buffer tank.
The process of gap distillation involves adding the raw material liquid into the tower kettle at once, without adding any materials in the entire operating procedure. After the liquid in the kettle is heated to boiling, the generated steam is condensed in the condenser at the top of the tower through the packing layer. The condensed liquid is refluxed/extracted through the reflux ratio electromagnetic pendulum. Generally, gaps are used for fine products, so the raw material components are relatively large, so the reflux ratio can be adjusted arbitrarily. At the same time, the tower top receiving tank is also prepared with three storage tanks for receiving the front distillate, middle distillate, and finished product. The distillation process can be switched freely.
