Description
Technical field
The present invention relates to a kind of ion-exchange reactions and regenerating units.
Background technique
In boiler feedwater, in the pure water and ultrapure water apparatus applied in photovoltaic element and production of electronic components, ion is handed over
Changing device is widely used.
Mixed bed ion-exchange method is exactly placed on anion and cation exchange resin in the same exchanger, before operation
They are uniformly mixed, so can look at is to answer bed by the countless staggered multi-stags of yin, yang exchanger resin, institute's saliferous in water
The anions and canons of class then by resins exchange, and obtain high pure water by this exchanger.In mixed bed, due to yin, yang
Resin mutually mixes, so its anions and canons exchange reaction almost carries out simultaneously, in other words, the cation exchange of water and
Anion exchange is repeatedly staggeredly to carry out, and exchanges generated H through H-type+Generated OH is exchanged with by OH type-All cannot
Accumulate, substantially eliminate the influence of counter ion, exchange carry out ratio more thoroughly.Due to entering the primary pure water matter of mixed bed
Preferably, the light load of exchanger, the exchange capacity of resin for a long time just exhaust by quilt.
Mixed bed uses internal method of reproduction, different first with the specific gravity of two kinds of resins when regeneration, with backwash right to use yin,
Cation exchange resin is kept completely separate, and positive resin is deposited on down, and negative resin floats on above, and then positive resin is with hydrochloric acid (or sulfuric acid)
Regeneration, negative resin are regenerated with sodium hydroxide.In hybrid resin regenerative process, the anion exchange resin and sun that will be mixed are needed
Ion exchange resin separates, and anion exchange resin is since density is small on upper layer, and cation exchange resin density is greatly in lower layer.So
Enter resin from the both direction up and down of resin respectively with sodium hydroxide and hydrochloric acid afterwards, then utilizes collector will again in interface
Spent acid alkali mobile phone discharge after life.It is possible to will appear layering when layering unevenly, has caused a small amount of anion exchange
Resin is mixed in cation exchange resin or has a small amount of cation exchange resin to be mixed in anion exchange resin.It makes
Destruction is caused to resin instead when at regeneration, influences effluent quality and the cycle of operation.In cation exchange resin by Na+Type turns
Change H into+When type, the volume of resin can change, and similarly regeneration be easy to cause to be not thorough.
