Abstract
The invention discloses a mixed ion exchanger of a flotation bed. The mixed ion exchanger comprises a tank body, a water inlet and a water outlet, wherein the water inlet is formed in the bottom of the tank body; and the water outlet is formed in the top of the tank body. By setting the water inlet in the bottom of the tank body and the water outlet in the top of the tank body, industrial water to be treated firstly takes part in reaction with strong-acid cation-exchange resin, wherein the chemical formula is as follows: RH+NaHSiO3=RNa+H2SiO3, generated acidic water is used for improving subsequent ion exchange reaction, and qualified secondary desalted water is prepared; all resin at the upper, middle and lower parts in the tank body take part in the reaction, so that the running cycle of a mixed bed is prolonged, the cyclic water preparation amount is increased, and the outlet water quality is improved; as the industrial water enters from the bottom of the tank body, anion exchange resin and cation exchange resin are in suspension states, the surface of contact between the industrial water and the resin is increased, the exchange capability of the resin is brought into full play, the exchange effect is improved, the equipment running speed is increased, and the water yield is increased. The mixed ion exchanger is suitable for treating the industrial water.
Description
Technical field
The present invention relates to a kind of Industrial cleaning facility water treating equipment, particularly the 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 the described mixed bed, and mix, can regard as by countless anionite-exchange resin and Zeo-karb (abbreviation resin) to be staggered.The service water that contains the yin, yang ion enters from the top of described mixed bed, described yin, yang ion in described mixed bed by resins exchange, thereby obtain high-purity water in the bottom of described mixed bed.Behind described mixed bed operation for some time efficiency lost resin, need respectively anionite-exchange resin and Zeo-karb to be regenerated 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, (mixed bed internal upper part anionite-exchange resin accounts for more ratio so the easy mixing of anionite-exchange resin and Zeo-karb is inhomogeneous, the bottom Zeo-karb accounts for more ratio), thereby causing described mixed bed internal upper part is strongly basic anion exchange resin, the bottom is storng-acid cation exchange resin, like this, the yin, yang ion in the pending service water at first contacts with strong anion-exchange resin.But because pending service water mostly is greatly neutrality or slight alkalinity (mainly containing sodium ion and bicarbonate radical, silicate etc.), and HSiO
3Ion and the reaction of described strong anion-exchange resin generate the concrete reaction formula of NaOH(and are: ROH+NaHSiO
3=RHSiO
3+ NaOH), so such ion exchange reaction may be carried 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 owing to 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, the strong-acid cation-exchange resin reaction of they and mixed bed bottom: RH+NaHSiO
3=RNa+H
2SiO
3, so just cause containing in the water outlet H
2SiO
3Thereby so that the water after purifying is aobvious acid, specific conductivity also raises, and so that mixed-bed effluent quality deterioration.Simultaneously, only be the resin that mixes of middle that part of mixed bed owing to what ion exchange really can occur, so the resin utilization ratio is lower, so just so that the mixed bed cycle of operation is short, water production in periodic mode descends, effluent quality worsens.
Summary of the invention
The objective of the invention is provides the floating bed that a kind of effluent quality is good, the cycle of operation is long, water production in periodic mode is high and water production rate is large mixed ion exchanger in order to overcome the deficiency of above-mentioned background technology.

3=RNa+H
2SiO
3, the sour water of generation has improved the ion exchange reaction of follow-up middle tank body middle part hybrid resin and top strong anion-exchange resin, makes qualified secondary de-mineralized water; The resin of tank body internal upper part, middle part and bottom all participates in reaction, has prolonged the cycle that mixed bed is moved, has improved water production in periodic mode, has improved effluent quality; Because service water enters from tank base, so anionite-exchange resin and Zeo-karb are in suspended state, has increased the contact surface of service water and resin, given full play to the exchange capacity of resin, improve the exchange effect, increased equipment operation flow velocity, improved water production rate.
In such scheme, the position of the corresponding described water outlet in described tank body top is provided with water cap mounting plate, and described upper water cap mounting plate is provided with the water cap.The upper water cap that adds has avoided water outlet to take resin out of tank body and water outlet is even; Simultaneously, described upper water cap can make regeneration alkali lye fully contact with resin.
