Comprehensive energy saving method for distillation of liquor

Abstract

The invention discloses a comprehensive energy saving method for distillation of liquor. Flash evaporation is carried out in order to recover heat energy in hot water after cold water condenses wine steam in the form of steam, the steam and secondary steam in a wine steamer are used for carrying out warming and supercharging through increasing enthalpy by phase transition and a stream ejector, in order to realize simultaneous high efficient recovery as well as warming and supercharging of low grade hot water heat energy and secondary steam heat energy, and realize the purpose of spot utilization. Compared with the traditional wine steaming system, the energy consumption is reduced by 30% or above, the system does not have power consumption and moving parts, the structure is simple, installation is simple, maintenance workload is small, and the method is very suitable for engineering needs. In the traditional liquor brewage process, except the wine distilling system with large energy consumption, hot water is extracted through flash evaporation in order to obtain steam, the steam passes through the phase transition enthalpy increasing system and the phase transition enthalpy increasing heat pump with steam spraying, the temperature and the pressure of the steam heat energy are increased and reach nearby the requirements for applications, and the problems of large energy consumption and unnecessary carbon emission caused by the energy consumption in the traditional liquor brewage process and the like are solved.

Description

technical field [0001] The invention belongs to the technical field of liquor distillation, and in particular relates to a comprehensive energy-saving method for liquor distillation. Background technique [0002] my country is a big country in liquor consumption and production. In recent years, liquor production has grown rapidly. In 2015, the national liquor production reached 13.128 million kiloliters. However, due to historical reasons, most winemaking enterprises in my country are still in the extensive development mode of high investment, high consumption, high emission, and low efficiency. A sharp upward trend, high energy consumption, low output, and high emissions have always been important issues that plague the development of liquor companies. According to relevant data, every ton of liquor produced in my country consumes 2-3 tons of grain, 0.6-1.5 tons of coal, and produces 8-10 tons of distiller's grains. The phenomenon of low production and high consumption of h...
