Abstract

The present invention discloses a waste brine reuse system using waste brine in a sugar refinery to wash bagasse ash in flue gas discharged from a bagasse boiler. The system comprises: a housing and a liquid inlet tube, wherein the housing is a vertically arranged cylindrical structure; a gas inlet is formed in the lower side wall of the housing; the gas inlet is arranged along the circumferential and tangential direction, and is used for receiving the flue gas; a gas outlet is formed in the top of the housing; and the liquid inlet tube is arranged on the upper part of the housing, and is used for guiding the waste brine into the housing, and enabling the waste brine to downwards flow along the inner wall of the housing. The waste brine reuse system provided by the invention can effectively remove the bagasse ash in the flue gas from the bagasse boiler, and the water consumption of the sugar refinery is greatly reduced because of the repeated use of waste brine.

Description

technical field [0001] The invention relates to a reuse system of waste brine from sugar factories. Background technique [0002] After a certain period of production, the ion exchange resin in the refined sugar factory has absorbed more pigment impurities in the syrup, and cannot achieve the best performance. That is to say, it is necessary to use a certain amount of brine, caustic soda and hydrochloric acid to form brine to clean and regenerate the resin to achieve the best performance. Usually, to maximize the recovery of regenerated brine, the ion exchange resin decolorization system generally has its own preparation and recovery system for regenerated brine, but this system can generally only process and recover a certain amount of discharged brine, and there is a small amount of discharged brine at the end of recovery It has been recycled many times, and this part of brine is called waste brine. The waste brine has a high concentration and has no value of recovery, a...
