Abstract

The invention discloses molasses alcohol fermented mature mash multi-effect evaporation concentration integrated equipment and process. The equipment comprises five effect evaporating pots, a separation chamber of the previous effect evaporating pot is communicated with a heating chamber of the next effect evaporating pot, and a mature mash pot is communicated with a heating chamber of the fourth effect evaporating pot; a heating chamber of the first effect evaporating pot is communicated with a condensing water collection pot, heating chambers of the second, third and fourth effect evaporating pots are communicated with a pure water collection pot, and a heating chamber of the fifth effect evaporating pot is communicated with an alcohol collection pot; a heating chamber of the third effect evaporating pot is communicated with a concentrated waste liquid collection pot. The molasses alcohol fermented mature mash multi-effect evaporation concentration integrated equipment has the advantages that a multi-effect differential pressure evaporation concentration system is used for replacing the alcohol separation extraction function of a mash tower, and can be used for concentrating residual waste liquid which can be used as boiler fuel after the residual waste liquid reaches a certain concentration, so that the fixed investment on equipment can be saved, energy consumption can be reduced, the production operation cost can be effectively reduced, and the problem of high difficulty in waste liquid treatment in molasses alcohol production process can be effectively solved.

Description

technical field [0001] The invention relates to an equipment and a process, in particular to an integrated equipment and process of multi-effect evaporation and concentration of molasses alcohol fermentation mature mash. Background technique [0002] The treatment process of starchy alcohol fermented mature mash is relatively simple, that is, after the alcohol is separated and extracted in the crude distillation tower, the remaining distiller's grains are press-filtered, and the filtrate is used for anaerobic treatment to generate biogas that can be used as fuel, and the filter residue can be used as fuel after treatment. As raw material of organic fertilizer or for feed processing. Because the material components in the waste liquid are mainly organic matter, the treated waste liquid can basically be discharged up to the standard, and the operating cost is relatively low. [0003] The treatment process of molasses alcohol fermentation mature mash (that is, the alcohol semi...
