Problems solved by technology

[0002] As the condensate at the end of the alcohol rectification condenser, industrial alcohol is the head-level impurity in the production of fermented alcohol. It contains acetaldehyde, a small amount of ethanol, methanol and other impurities, which affect the quality of alcohol products and reduce the yield of product alcohol. The by-product is sold as a cleaning agent in the foundry industry, and the price is extremely low; it seriously affects the cost of alcohol, and at the same time produces a certain amount of pollution. In the prior art, the method of direct discharge of aldehyde pipes is often used, which is not ideal and causes waste.

Abstract

The invention discloses an industrial alcohol reflux re-fermentation process. The process comprises a fermentation tank, a return pipeline connected with the top of the fermentation tank, a first condenser connected with the return pipeline, a recovery pipeline used for collecting pipeline flushing water, a pipeline alcohol storage tank connected with the recovery pipeline, a blow-off pipe arranged below the pipeline alcohol storage tank, a delivery pump connected with the pipeline alcohol storage tank, a preheater connected with the conveying pump, a coarse distillation tower connected with the preheater, a rectifying tower connected with the coarse distillation tower, a second condenser connected with the rectifying tower, an alcohol circulating pump connected with the second condenser, a buffer tank connected with the alcohol circulating pump and a finished product storage tank connected with the buffer tank. The backflow impurities such as acetaldehyde and acetic acid can participate in the reaction again to generate ethanol, so that the yield of ethanol is increased, and the generation of impurities is reduced.

Description

technical field [0001] The invention relates to the field of alcohol processing, in particular to an industrial alcohol reflux re-fermentation process. Background technique [0002] As the condensate at the end of the alcohol rectification condenser, industrial alcohol is the head-level impurity in the production of fermented alcohol. It contains acetaldehyde, a small amount of ethanol, methanol and other impurities, which affect the quality of alcohol products and reduce the yield of product alcohol. The by-product is sold as a cleaning agent in the foundry industry, and the price is extremely low; it seriously affects the cost of alcohol, and at the same time produces certain pollution. In the prior art, the method of direct discharge of aldehyde through the pipeline is mostly used, which is not ideal and causes waste. Contents of the invention [0003] Aiming at the above-mentioned technical problems, the invention provides a kind of industrial alcohol reflux re-ferment...
