Abstract

The invention discloses an absolute ethyl alcohol production device. The absolute ethyl alcohol production device comprises a feeding pump, an enzymolysis tank, a fermentation tank, a distillation tank, an overheater and an adsorber which are connected in sequence. A steam inlet pipe A is arranged at the bottom of the enzymolysis tank. A stirrer is arranged at the bottom end of the enzymolysis tank. A stirrer is arranged at the bottom end of the fermentation tank. A stirring bar is arranged on the upper portion of each stirrer. A U-type guide pipe connected with the fermentation tank is arranged at the bottom of the enzymolysis tank. A feeding port is formed in the top of the fermentation tank. The bottom of the fermentation tank is connected with the top of the distillation tank through the guide pipe. A steam inlet pipe B is further arranged at the bottom of the distillation tank. A steam guide pipe A communicated with the overheater is arranged at the top of the distillation tank. A heat exchanger (6) is connected with the adsorber through a steam guide pipe C. A heat exchanger A is arranged below the adsorber. An absolute ethyl alcohol collecting tank is arranged at the bottom end of the heat exchanger A. The device has the advantages of being low in energy consumption, high in production efficiency, low in cost, simple in structure and high in recovery rate, and concentration of absolute ethyl alcohol is high.

Description

technical field [0001] The invention belongs to the technical field of fine chemicals, and in particular relates to an anhydrous ethanol production device. Background technique [0002] Absolute ethanol refers to ethanol with a concentration greater than 99% (mass), which is a basic chemical raw material. It is widely used in chemical, pharmaceutical, pesticide, dye, ink, adhesive, paint, spice, cosmetic, detergent, rubber and other industries. In recent years, with the world's energy crisis and increasingly tense use, the demand for anhydrous ethanol has grown rapidly. The largest consumer market for anhydrous ethanol in foreign countries is as fuel, especially automobile fuel. [0003] Generally, the highest concentration of industrial ethanol produced is 95%. In order to obtain anhydrous ethanol, the following three methods can be used for further dehydration: ①Treat industrial ethanol with quicklime to convert water into insoluble calcium hydroxide, then distill ethano...
