Description

For the rectifier unit of fusel oil

Technical field

The utility model is related to a kind of rectifier unit, method and its application, especially a kind of rectifying for fusel oil fills It puts.

Background technology

Alcohol industry is basic material industry, and product is for food, chemical industry, military project, medicine and other fields：Fusel oil be with Starch or molasses produce one of by-product of alcohol for raw material, are breaks down proteins and the secondary hydrolysis of mycoprotein in fermentation raw material Product, be containing there are many alcohols mixed liquor general designation, the growing amount of fusel oil is related to fermentation raw material and technique, generally generates Amount accounts for the 0.3%-0.8% of alcohol output.Fusel oil is a kind of pale yellow oily liquid, there is off-odor and toxicity.Its master It is the aldehyde of isoamyl alcohol, isobutanol, normal propyl alcohol, ethyl alcohol, water and a small amount of boiling point more than 135 DEG C, alcohol, ester, acid, unsaturated terpene to want ingredient It is high to be that raw material can go out tens of kinds of added values with deep processing development with fusel oil for vinyl compound etc., up to 22 kinds of complicated ingredients Fine chemical product, these products suffer from being widely applied in the industries such as plastics, coating, feed, chemical industry, food, medicine, Existing in the rectifier unit of fusel oil, generally using batch distillation, fusel oil to be used from storage tank for fusel oil separation Pump is beaten to stirring in drain sump, is added in a certain proportion of Nacl i.e. dehydrating agent and is stirred dehydration, through precipitating separation.By salt and Water recycles after releasing, and dewatered fusel oil pump is delivered to distillation still, heating distillation is carried out by reboiler, according to component Boiling point it is different, control distillation tower top temperature, can obtain different products, after the product of taking-up is cooled down by condenser, Sampling analysis is qualified into pans, finally with being pumped into product storage tank or barreled export trade.It is underproof to return in distillation still, after Temperature of continuing rising, heating, separation.Existing device is distillation indirectly, the quantity of steam of consumption it is big and can not continuous production, be not convenient to use Automation control has very big restriction to the promotion of the yield and quality of product, and the partial devices also having are using normal pressure essence Mode is evaporated, a tower isolates a kind of component, solves continuous production, the problem of convenient for automation control, but steam consumption Amount is big.

Based on it is existing the technical issues of, technical characteristic and technique effect, make the application technical solution of the utility model.
