Description

Technical Field

[0001] The utility model relates to a reflux ratio controller and belongs to the technical field of biopharmaceutical equipment. Background Art

[0002] The reflux ratio controller is a device that can be installed inside or outside a distillation tower to control the diversion. The advantages of this device are that it can reduce the labor intensity of the operator, is intuitive, easy to operate, easy to maintain, and reliable in operation. The reflux volume can be adjusted at any time period, and the ratio of the reflux volume in the tower to the extraction volume can be accurately controlled. It is suitable for conventional distillation in intermittent and continuous operation, as well as special distillation processes such as extractive distillation and constant boiling distillation. It is particularly suitable for high-condensation and high-boiling distillation.

[0003] In distillation operation, the reflux ratio R is the ratio of the reflux liquid flow L from the top of the distillation tower to the top product flow D, that is, R = L / D. The size of the reflux ratio has an important impact on the separation effect and economy of the distillation process; adjusting the reflux ratio is mainly to control the concentration of the top product, while taking into account the consumption of cold and hot energy. The size of the reflux ratio can reflect the energy consumption of the distillation tower and the quality of the operating conditions. Therefore, in the design of distillation, the appropriate reflux ratio size and precise control can bring good economic benefits to the production of enterprises.

[0004] At present, domestic fine chemicals mostly use three-way automatic control valves and funnel-type reflux devices for distillation discharge control. That is, a three-way automatic control valve or a funnel-type reflux device is installed to adjust the discharge ratio. However, because fine chemicals require fast switching speed, the three-way automatic control valve often cannot meet the switching requirements, and the funnel-type reflux device may cause the funnel conversion to deviate due to the strong flushing of the material. Therefore, the existing controller needs to be improved to meet the production requirements. Summary of the invention

[0005] The utility model aims to provide a reflux ratio controller to solve the problem mentioned in the background technology that the three-way automatic control valve often cannot meet the switching requirements due to the fast switching speed required by fine chemical industry, and the funnel-type reflux device may cause the funnel conversion to deviate due to the strong flushing of materials.
