Problems solved by technology

Although this method can effectively treat alcohol waste liquid, it needs to consume a large amount of primary steam as a heat source for evaporation and concentration, which has problems such as high energy consumption and high operating costs.
[0004] The main reason for the high energy consumption in the production of molasses alcohol is that the evaporation and concentration of alcohol waste liquid requires a lot of heat. The secondary steam generated in the evaporation has no other use and enters the condenser to condense, resulting in a large loss of waste heat. In addition, the secondary steam needs to be cooled. Water cooling, consumes a lot of cooling water

Abstract

The invention discloses a molasses alcohol waste liquor evaporation and concentration system serving as a heat source of an alcohol distillery. Materials pass through a V-effect evaporator, an IV-effect evaporator, an III-effect evaporator, a first heater, a clarification tank, a second heater, a third heater, an I-effect evaporator and an II-effect evaporator in the flowing direction of molasses alcohol waste liquor; low-concentration alcohol waste liquor at the temperature of 80 DEG C from the distillery enters a V-effect evaporation tank and is pumped into an IV evaporation tank and an III-effect evaporation tank. Medium-concentration alcohol waste liquor from the III-effect evaporation tank is heated to 95 DEG C or higher by the II-effect juice steam and the first heater, enters the clarification tank to be clarified, is heated to 105 DEG C by the second heater, the third heater and I-effect juice steam and enters the I-effect evaporation tank and the II-effect evaporation tank. Secondary steam generated through multi-effect evaporation of the waste liquor is used for an energy-saving reconstruction technique for alcohol distillation, the use amount of primary steam during alcohol production is reduced, the energy consumption during alcohol production is reduced, and the production and operation costs are saved.

Description

technical field [0001] The invention relates to the technical field of treatment devices for molasses alcohol waste liquid, and more specifically relates to an evaporation and concentration system for molasses alcohol waste liquid used as a heat source in an alcohol distillation room. Background technique [0002] At present, molasses, the main by-product of Guangxi Sugar Factory, is mainly used as a raw material for the production of industrial alcohol. High energy consumption is an urgent problem faced by molasses alcohol production. With the improvement of national standards for energy conservation and consumption reduction in industrial production, the issue of energy conservation has become increasingly important to alcohol production enterprises. In order to comply with the requirements of the national energy-saving policy and to reduce the cost of production and operation, the research on the method of energy-saving transformation of alcohol distillation to reduce th...
