(303) inlet and outlet check valve enables the third adsorption column (303) and continues adsorption treatment, while external steam (7) being passed through
Pipeline and check valve introduce the second adsorption column (302), are regenerated using the activated carbon in the second adsorption column of steam pair (302);
It regard the first adsorption column (301) as station set;When the recycling ethyl alcohol of third adsorption column (303) processing is detected through photometer (6)
When unqualified, by the inlet and outlet non-return valve switches of third adsorption column (303) to the inlet and outlet check valve of the first adsorption column (301),
It enables first adsorption column (301) and continues adsorption treatment, while external steam (7) is introduced into third by pipeline and check valve
Adsorption column (303) regenerates the activated carbon in third adsorption column (303) using steam;By the second adsorption column (302) conduct
Station set;The regenerated indirect steam of first adsorption column (301) enters the second condenser by its pipeline and check valve
(202) (or second adsorption column (302) regenerated indirect steam enters the second condenser by its pipeline and check valve
(202) or the third adsorption column (303) regenerated indirect steam enters the second condenser by its pipeline and check valve
(202)), the outlet of second condenser (202) is connect by pipeline with the second fluid reservoir (502), second fluid reservoir
(502) storage receive the first adsorption column (301), the second adsorption column (302) or third adsorption column (303) indirect steam through second condensation
Device (202) condensed liquid, it can be as the raw material for recycling ethyl alcohol with rectifying column.
8. the device according to claim 7 recycled for ethyl alcohol in extraction of traditional Chinese medicine, which is characterized in that the evaporation
Device (1) can use extractor or concentration tank or rectifying column to replace, and the mixture of ethyl alcohol and medicinal material is housed in the extractor, to be recycled
Be ethyl alcohol in the dregs of a decoction;Ethanol extract containing traditional Chinese medicine ingredients is housed, to be recycled is in extracting solution in the concentration tank
Ethyl alcohol;The mixed solution or precipitation solution of ethyl alcohol and water are housed, to be recycled is the mixed solution of ethyl alcohol and water in the rectifying column
Or the ethyl alcohol in precipitation solution.
9. the device according to claim 8 recycled for ethyl alcohol in extraction of traditional Chinese medicine, which is characterized in that carried described
The top of tank is taken to be equipped with steam (vapor) outlet pipeline, bottom equipped with solid discharge pipeline;It is equipped with vapor liquid at the top of the concentration tank
Export pipeline, bottom are equipped with extracting solution inlet ductwork.
