Abstract

The invention discloses an automatic alcohol recycling system which belongs to the field of pharmacy and solves the problems of high labor intensity, large workload, long working period and the like of the existing alcohol recycling system as the whole alcohol recycling process is operated manually. In the invention, multiple waste ethanol storage tanks are arranged in parallel; an exit of each waste ethanol storage tank is connected with a pre-heater; a connection pipeline is provided with a first feed pump and a feed regulation valve; an exit of the pre-heater is connected with a waste ethanol inlet of an alcohol recycling tower; a dilute alcohol outlet is arranged at the bottom of the alcohol recycling tower; a reboiler is connected in series between the dilute alcohol outlet and an entrance; a wastewater outlet is formed on the pre-heater; the top of the alcohol recycling tower is provided with an alcohol steam outlet; a cooling water loop is connected in series with a first overhead condenser; and one part of the alcohol discharged by the condenser returns to the alcohol recycling tower through a return tank and a first return pump, and the other part enters a finished product ethanol storage tank through a finished product alcohol regulation valve and a finished product condenser. The automatic alcohol recycling system disclosed by the invention is used for recycling waste alcohol.

Description

technical field [0001] The invention relates to an automatic alcohol recovery system and belongs to the field of pharmacy. Background technique [0002] Alcohol recovery system is widely used in pharmaceutical, food and other industries, and its main function is to realize the recovery and reuse of alcohol. At present, the alcohol recovery system used by domestic pharmaceutical factories is almost completely controlled manually, and its automation control level is low. The main problems are as follows: [0003] 1. The recovery rate and finished product quality are unstable due to human factors. [0004] 2. The environmental indicators of emissions are unqualified. [0005] 3. The whole process is manually operated, and the labor intensity is high. [0006] 4. Heavy workload and long working cycle. [0007] 5. There are many monitoring points and the operation is complicated. [0008] 6. Serious waste of energy. [0009] 7. There is no automatic alcohol recovery system i...
