Description
Technical field
The utility model relates to a kind of Industrial cleaning facility water treating equipment, particularly floating bed mixed ion exchanger.
Background technology
At present, the general fixed bed yin, yang mixed ion exchanger (abbreviation mixed bed) that adopts of industry is processed service water, filling anionite-exchange resin and Zeo-karb in described mixed bed, and mix, can regard as by countless anionite-exchange resin and Zeo-karb (abbreviation resin) and be staggered.Containing the service water of yin, yang ion, from the top of described mixed bed, enter, described yin, yang ion in described mixed bed by resins exchange, thereby obtain high-purity water in the bottom of described mixed bed.After described mixed bed operation for some time efficiency lost resin, need to anionite-exchange resin and Zeo-karb, be regenerated respectively with alkali, acid regeneration liquid, make resin recover exchange capacity.But there is following problem in described mixed bed:
Because the proportion of described anionite-exchange resin is little, the ratio of Zeo-karb is great, so the easy mixing of anionite-exchange resin and Zeo-karb is inhomogeneous, (mixed bed internal upper part anionite-exchange resin accounts for more ratio, the bottom Zeo-karb accounts for more ratio), thereby causing described mixed bed internal upper part is strongly basic anion exchange resin, bottom is storng-acid cation exchange resin, like this, at first the yin, yang ion in pending service water contacts with strong anion-exchange resin.But because pending service water is mostly neutrality or slight alkalinity (mainly containing sodium ion and bicarbonate radical, silicate etc.), and HSiO
3ion reacts the concrete reaction formula of generation NaOH(with described strong anion-exchange resin: ROH+NaHSiO
3=RHSiO
3+ NaOH), thus such ion exchange reaction may carry out hardly; Like this, described NaHSiO
3directly enter the mixed bed middle part, with the strong-acid cation-exchange resin generation ion exchange reaction at middle part: RH+NaHSiO
3=RNa+H
2siO
3, the H of generation
2siO
3with strong anion-exchange resin generation ion exchange reaction: ROH+H
2siO
3=RHSiO
3+ H
2o; But because the anionite-exchange resin on mixed bed top does not play one's part to the full, so must also have some NaHSiO
3and H
2siO
3enter into the mixed bed bottom, they react with the strong-acid cation-exchange resin of mixed bed bottom: RH+NaHSiO
3=RNa+H
2siO
3, so just cause in water outlet containing H
2siO
3thereby, make the water after purification aobvious acid, specific conductivity also raises, and makes mixed-bed effluent quality worsen.Simultaneously, due to what ion exchange really can occur, be only the resin mixed of that part in the middle of mixed bed, so the resin utilization ratio is lower, so just make that the mixed bed cycle of operation is short, water production in periodic mode descends, effluent quality worsens.
