Starch production waste water recycling system and using method thereof

Abstract

The invention relates to the field of starch production, and particularly to a starch production wastewater recycling system and a use method. The starch production wastewater recycling system comprises a wastewater pond, a cold water tower, a surface condenser and a vacuum pump. The wastewater pond and the cold water tower are connected to each other via a cold water pipe; the wastewater pond and the surface condenser are connected to each other via a condenser pipe; the wastewater pond and the vacuum pump are connected to each other via a sealing water pipe; the cold water tower and the surface condenser are connected to each other via a heat exchange; and the cold water tower and the vacuum pump are connected to each other via a sealing water pipe. Compared with the prior art, the starch production wastewater recycling system and use method provided by the invention have the following advantages and positive effects: the system and use method take into account the feature that the wastewater produced during starch production is acidic, thereby solving the technical problems that conventional use is likely to cause scaling and incur damage to equipment, and saving water resources and protecting the environment.

Description

technical field [0001] The invention belongs to the field of starch processing, and in particular relates to a starch production waste water recycling system and a use method. Background technique [0002] Starch is a polysaccharide. Starch can be regarded as a high polymer of glucose. In addition to food, starch can also be used in the industry to make dextrin, maltose, glucose, alcohol, etc. It is also used to prepare printing paste, sizing of textiles, gluing of paper, and pressing of pharmaceutical tablets. Therefore, the demand for starch Very big. [0003] Corn, also known as sorghum, originated in South America, and then spread to Asia from Europe and Africa. Corn has been cultivated in my country for more than 470 years. It is one of the three major food crops in the world. Because it is a dry land crop, it has high yield per unit area and great potential for increasing production, so it plays an important role in agricultural production. Because the proportion o...
