Problems solved by technology

[0003] According to the analysis of the rectification process, in order to realize the rectification separation operation, the rectification tower must have enough layers of trays, so the volume of the traditional rectification device is relatively large; the rectification tower must also introduce the descending liquid flow from the top of the tower and the Generate rising steam flow to establish a vapor-liquid two-phase system, so the energy consumption is relatively large

The invention relates to a rectify device. It has raw material cans,raw material pump and Jacket vacuum vaporization tank; Also with at least two vapor condensation catchers, Roots pumps set in the intake manifold of the vapor condensation catcher, and condensing collection link the bottom of the vapor condensation catcher, each of the vapor condensation catcher with the refrigerator, heat exchangers and the expansion valve composed cooling circulatory system, the out trachea of first-class vapor condensation catcher connected with the Roots pump of second-class vapor condensation catcher, out trachea of the final one vapor condensation catcher connected with rotary pump, heat exchanger in the different cooling circulatory system installed in a vacuum evaporation tank jacket or installed in raw materials in the tank. This invention's advantages are lower power consumption, simple structure, smaller volume, the distilled production with many varieties, high purity.

Description

technical field [0001] The invention relates to a distillation device with rectification function. Background technique [0002] The traditional rectification device has a reboiler, a rectification tower, a preheater and a condenser. After the raw material liquid is heated to a specified temperature by the preheater, it is sent to the feed plate of the rectification tower. After the reflux liquid falling from the upper part is combined, it overflows plate by plate, and finally flows into the reboiler at the bottom of the tower; on each plate, the reflux liquid and the rising vapor contact each other to conduct heat and mass transfer processes. During operation, the liquid in the reboiler is continuously vaporized after being heated and decompressed, and rising steam is generated, which passes through each layer of trays in turn, and the steam at the top of the tower enters the condenser to be completely condensed, and part of the condensate is sent back to the top of the tow...
