Abstract

The invention provides a riboflavin fermentation wastewater evaporative crystallization system. An air inlet of a first-effect evaporator is communicated with a steam source, a feeding hole of the first-effect evaporator is communicated with a riboflavin fermentation wastewater source, a discharging hole of the first-effect evaporator is communicated with a feeding hole of a second-effect evaporator, an air outlet of the first-effect evaporator is communicated with an air inlet of the second-effect evaporator, an air outlet of the second-effect evaporator is communicated with an air inlet of the third-effect evaporator, a discharging port of the second-effect evaporator is communicated with a feeding port of the third-effect evaporator, a discharging port of the third-effect evaporator is communicated with a feeding port of a discharging pump, and an air outlet of the third-effect evaporator is communicated with an air inlet of a condenser. Steam is used as an evaporation heat source to evaporate and crystallize the riboflavin fermentation wastewater, sugar, protein and other substances in the riboflavin fermentation wastewater are recycled, the recycling efficiency is high, and the occupied area is small. Meanwhile, condensate water is used for preheating the riboflavin fermentation wastewater, and the purposes of reducing the use amount of steam and saving energy are achieved.

Description

technical field [0001] The invention relates to the technical field of waste water treatment equipment produced by riboflavin fermentation, in particular to an evaporation and crystallization system for riboflavin fermentation waste water used to produce protein feed using waste water produced by riboflavin fermentation. Background technique [0002] Riboflavin, also known as vitamin B2, is one of the thirteen essential vitamins in the human body. In the production of riboflavin, high-concentration organic wastewater will be produced during the refining process. The wastewater has the characteristics of high chroma, high salinity, high COD, high BOD, high bacterial content, etc., and contains a large amount of sugar, protein, SS and Ammonia nitrogen, these substances are not poisonous and harmful substances, which can be used by some microorganisms and animals in their growth and reproduction. If the riboflavin fermentation wastewater is discharged directly, it will not only...
