Problems solved by technology

[0002] In the production process of alcohol rectification still, the rectification of alcohol still is intermittent feeding, and the water in the rectification kettle is removed in the gap, so that the alcohol rectification takes a long time, the output is low, and the alcohol content in the rectification kettle drainage is high, which is not conducive to Alcohol recovery cannot be produced continuously. Therefore, it is necessary to develop a practical and convenient alcohol continuous distillation process with simple operation process, convenient operation, no need to cool down the drainage of the rectification tank, low energy consumption, and high output.

Abstract

The invention relates to an alcohol continuous rectifying still production process. The process includes the following steps of firstly, putting in a backing material; secondly, conducting continuous feeding; thirdly, conducting heating and rectifying; fourthly, conducting liquefying and condensing; fifthly, conducting secondary separating; sixthly, conducting continuous draining; seventhly, collecting a finished alcohol product; eighthly, collecting tail gas. The process has the advantages of being comprehensive in function, convenient and rapid to use and low in cost.

Description

technical field [0001] The invention belongs to the technical field of chemical production technology, and in particular relates to a production technology of continuous alcohol rectification still. Background technique [0002] In the production process of the alcohol rectification kettle, the rectification of the alcohol kettle is intermittent feeding, and the water in the rectification kettle is removed in the gap, so that the alcohol rectification takes a long time, the output is low, and the alcohol content in the rectification kettle drainage is high, which is not conducive to Alcohol recovery cannot be produced continuously. Therefore, it is very necessary to develop a practical and convenient alcohol continuous distillation process with simple operation process, convenient operation, no need to cool down the rectification tank drainage, low energy consumption and high output. Contents of the invention [0003] The purpose of the present invention is to overcome the...
