Background
At present, three resin towers are designed to be matched with a 6-kiloton/a caustic soda device in one period for secondary refining of brine before an electrolytic cell, and the refining process realizes full-automatic control. Two towers are connected in series for operation, the other tower is regenerated in an offline manner, after 24 hours, the first tower is regenerated in an offline manner, the second tower is lifted to be the first tower, and the regenerated tower is regenerated in an online manner to be the second tower.
See table below:
The resin tower in the lower line absorbs a large amount of metal cations Ca2+, Mg2+ and the like in the brine after running, and is regenerated through seven steps of water washing, backwashing, hydrochloric acid regeneration, water washing, NaOH regeneration, water washing and brine replacement, and the metal cations in the resin tower are eluted and replaced to recover the refining capacity of the resin tower on the brine. Regenerating once in each tower for 48 hours, wherein in the regeneration process, recovered brine generated by washing, backwashing and brine replacement enters a brine tank, and is pumped to a brine working section by a centrifugal pump to carry out salt dissolving; waste water generated by hydrochloric acid regeneration, water washing, NaOH regeneration and water washing enters a waste water tank, and is pumped to a sewage treatment section by a centrifugal pump for treatment; after a series of environmental protection treatments, the waste water is discharged after reaching the standard. Each tower regeneration can generate waste water 60.9m3 containing acid and alkali (after acid-alkali neutralization, NaCl is generated to be about 0.9126 t). The waste water discharged all year round is about 20300m3 (turn over NaCl 304 t), which not only consumes a large amount of power electricity and water treatment agents, but also increases the sewage discharge cost, wastes a large amount of NaCl, increases the product cost and brings huge pressure to the environmental protection work.
