The invention discloses continuous production equipment for absolute alcohol. The continuous production equipment for the absolute alcohol comprises a charging pump, an enzymolysis tank, a fermentation tank, a rectification tank, a superheater, an adsorber and a heat exchanger which are sequentially connected, wherein a steam inlet pipe A is arranged at the bottom of the enzymolysis tank, a U-shaped conduit connected with the fermentation tank is arranged at the bottom of the enzymolysis tank, a charging hole is also formed in the top of the fermentation tank, the bottom of the fermentation tank is connected with the bottom of the rectification tank, a steam inlet pipe B is also arranged at the bottom of the rectification tank, a steam conduit A communicated with the superheater is arranged at the top of the rectification tank, the superheater is connected with the adsorber by virtue of a steam conduit B, a steam conduit D connected with the heat exchanger is arranged at the top of the adsorber, a condenser A is arranged below the heat exchanger, and the bottom of the condenser A is connected with an absolute alcohol recycling tank. The continuous production equipment for the absolute alcohol has the advantages that fermented crude alcohol is directly rectified and dehydrated, continuous production of the absolute alcohol is realized, operation is easy and working efficiency is improved and also has the advantages of low energy consumption, low cost, simple structure, high alcohol purity and the like.
Description
technical field [0001] The invention belongs to the technical field of fine chemicals, and in particular relates to an anhydrous alcohol continuous production equipment. Background technique [0002] Absolute alcohol refers to alcohol with a concentration greater than 99% (quality), also known as absolute ethanol, 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 alcohol has grown rapidly. The largest consumer market for anhydrous alcohol in foreign countries is as fuel, especially automobile fuel. [0003] Generally, the highest concentration of industrial alcohol produced is 95%. In order to obtain anhydrous alcohol, the following three methods can be used for further dehydration: ①Treat the industrial alcohol with quicklime to convert the wa...
