Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of chemical equipment, and in particular relates to a micro-flow reflux ratio controller based on time control. Background Art
[0002] In the distillation operation, the ratio of the reflux liquid flow rate L returned from the top of the distillation tower to the top product flow rate 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. Therefore, in the distillation design, the reflux ratio is a parameter that needs to be carefully selected. Usually, mechanical methods are used to control the fluid flow returning to the reflux pipe, such as the opening of the valve, or a distribution tank controlled by a connecting rod. However, for the tiny flow in the laboratory, the mechanical accuracy error is often unacceptable, and a small deviation will cause erroneous results. Utility Model Content
