Problems solved by technology

[0005] The disadvantages of this scheme are: although this process can produce polished cation resin, not only the production cycle is as long as 35 hours; and the amount of waste water containing salt, acid and alkali is extremely large; The waste water is as high as 30 tons; this process cleans out TOC through the process of acid-base transformation and expansion, which has extremely low efficiency and consumes a large amount of acid, alkali, and ultra-pure water; the removal of chroma by steam cleaning is very low in efficiency and consumes a lot of water ; the effect is still not satisfactory

Abstract

The invention discloses an efficient and environment-friendly polishing cation resin production system and production process, in particular to a production system and production process of low-material consumption, short production cycle, and low-yield waste polishing cation resin; industrial grade H containing metal ions + Add the type cation exchange resin 001×7 into the high-efficiency TOC cleaner, add 2 times the volume of 15 megohm (resistivity) ultrapure water to wash for 1 hour; filter the washing liquid, and put the cleaned cation resin into the conversion column ; drop into the conversion column through the high position tank, the flow rate is 2 times the volume per hour; after the end, use 2 times the volume of 15 megohm (resistivity) ultrapure water to clean to neutral, then it is a finished product; H + Type rate ≥ 99.7%.

Description

technical field [0001] The invention belongs to the technical field of polishing resin production equipment and production technology, in particular to an efficient and environment-friendly polishing resin production system and production technology. Background technique [0002] The existing polishing cation resin is produced, and the acid-base method is used to prepare the polishing cation resin. The production method is: [0003] [0004] Specifically: hydrochloric acid transformation → ultrapure water cleaning → hydrochloric acid transformation → ultrapure water cleaning → liquid alkali transformation → ultrapure water cleaning, and so on for 10-14 cycles until TOC is less than 1PPb and the transformation rate is ≥ 90%. [0005] The disadvantages of this scheme are: although this process can produce polished cation resin, not only the production cycle is as long as 35 hours; and the amount of waste water containing salt, acid and alkali is extremely large; The waste ...
