Differential pressure type solid continuous distillation process

Abstract

The invention relates to a differential pressure type solid continuous distillation process, comprising the steps of: placing solid materials on a tower plate in a distillation tower, introducing vapor to the bottom of the tower plate for heating, collecting vapor by vaporizing materials from an outlet pipe at the upper part of the tower plate, and condensing the collected vapor by a condenser toobtain the product, wherein the heating process comprises a preheating loop, a distilling loop and a residual distilling loop. In the invention, the distillation process has scientific and reasonabledesign, realizes fast and efficient continuous distillation process by arranging different operation conditions in each loop, has the advantages of simple operation, large processing load, high production efficiency, high yield and the like, and can efficiently guarantee the consistency stability of the final product of distillation simultaneously.

Description

technical field [0001] The invention relates to a solid-state distillation process, in particular to a differential-pressure solid-state continuous distillation process. Background technique [0002] Solid state distillation is more common in the concentration and separation of alcohol from solid materials. At present, the devices used in solid-state distillation are typical and traditional distillation retorts. High-pressure steam is introduced into the bottom of the retort, and the separated alcohol-containing vapor is collected at the top of the retort, and condensed by a condensing device to obtain concentrated alcohol. . However, the existing distillation process is all intermittent operation, and only one batch of materials can be quantitatively processed at a time. After the materials complete this distillation, they need to be taken out from the retort, and then the next batch of materials can be distilled. Therefore, the existing distillation process cannot realiz...

Problems solved by technology

However, the existing distillation process is all intermittent operation, and only one batch of materials can be quantitatively processed at a time. After the materials complete this distillation, they need to be taken out from the retort, and then the next batch of materials can be distilled

Therefore, the existing distillation process cannot realize continuous distillation, and has the disadvantages of small processing capacity, low degree of automation, low processing efficiency, high labor intensity, and low yield; at the same time, due to the intermittent distillation process, the concentration of the product obtained by distillation is unstable and cannot meet Continuous distillation process requirements for industrial mass production
