Problems solved by technology

Although this method can prepare and provide fresh brine for resin regeneration, there are still many defects in the production process and other details. On the one hand, more sediment in the salt pool is often pumped to the static tank, which affects the static precipitation effect. The freshly prepared brine has a small amount of floc, which affects the regeneration effect of the resin

Abstract

The invention discloses a device and a method for preparing fresh brine. The prepared brine is used for cleaning ion exchange resin. The device comprises a standing tank and a sand filter, wherein the standing tank is used for standing of a mixed solution of a sodium chloride solution and a sodium hydroxide solution; the sand filter adopts a vertically arranged tank structure, a liquid inlet of the sand filter is formed in the bottom of the sand filter and is communicated with a liquid outlet of the standing tank, quartz sand used for filtering the mixed solution is arranged in the middle of the sand filter, and a liquid outlet of the sand filter is formed in the top of the sand filter. The fresh brine contains no precipitation and floccules and has a good washing regeneration effect on the ion exchange resin, the conductivity and the ion concentration of the fresh brine can be controlled, and demands in various situations are met.

Description

technical field [0001] The invention relates to the preparation of fresh brine. More specifically, the present invention relates to a device and method for preparing fresh brine, and the prepared fresh brine is used for cleaning ion exchange resins in sugar factories. Background technique [0002] The ion exchange decolorization resin used in the sugar factory is generally used for the decolorization of syrup. After a certain period of treatment, the ion exchange resin absorbs more pigment impurities in the syrup and cannot achieve the best performance. At this time, it is necessary to prepare fresh brine to clean and regenerate the resin according to the type of resin. Generally, fresh brine prepared with brine, caustic soda and hydrochloric acid is used to clean and regenerate the resin to achieve the best performance. [0003] The existing method for preparing fresh brine is: artificially put edible salt into a salt pool with a certain amount of water, after fully stirri...
