The ion exchange device can automatically distribute the ion exchange columns according to treatment capacity, thus improving the treatment efficiency. Washed resin returns to the ion exchange columns, so that the resin is washed in time and reused, the resin consumption is reduced, and the utilization ration of the resin is high. The ion exchange device has the advantages of simplicity in operation, compact structure, low labor intensity and the like.
Description
Technical field
The utility model relates to a kind of ion interchange unit, is specifically related to ion-exchange unit.
Background technology
Ion-exchange is to exchange by means of the ion in the solid ion exchanger and the ion in the weak solution, to reach the purpose of extracting or removing some ion in the solution, is a kind of unit operations that belongs to the mass transfer separation process.Ion exchange technique is a kind of liquid phase separation techniques, has good separation selectivity and good effect.In chemical industry, food, medicine, hydrometallurgy, water treatment, field of environment protection recovery, enrichment and purifying operation, be used widely.
Since the ion exchange technique commercial Application, people just are devoted to the developmental research of ion-exchange unit always.The main type of ion-exchange unit has: 1. tank diameter is applicable to the processing thick liquid.When single-stage exchange does not reach when requiring available multistage composition cascade.2. fixed-bed ion exchanger also claims ion exchange column, is the fixed bed mass transfer apparatus for ion-exchange, and is most widely used.3. the moving bed ion-exchanger is the moving bed mass transfer apparatus for ion-exchange, because technical difficulty does not obtain commercial Application as yet.Though at present the industrial ionic switching equipment has developed into sizable scale, diameter reaches 4～6m, and disposal ability reaches 103～104m3/h, also has some shortcomings, and is low as the resin utilization rate, resin demand is big, floor space is big, the equipment investment expense is high.
At the ion-exchange unit present Research, the utility model will propose a kind of easy and simple to handle, be easy to control, efficient height, ion interchange unit that cost is low.
Summary of the invention
The purpose of this utility model provides that a kind of resin demand is few, efficient is high, ion interchange unit simple to operate.
The purpose of this utility model realizes by following technology:
The utility model mainly comprises ion exchange system, ion-cleaning system.Wherein ion exchange system is that several ion exchange columns form, between the two adjacent exchange columns for being connected in series.The ion-cleaning system mainly comprises the resin scrubbing tower.The resin outlet of ion-exchange column bottom links to each other with the resin scrubbing tower.
Described ion exchange system is made up of 2～5 ion exchange columns, and wherein ion exchange column is diameter 100～400mm, and the cylinder of high 500～2000mm contains the solion that is exchanged and passes through each ion exchange column successively.
Two outlets are arranged at the top of described ion exchange column, can select to enter down one deck exchange column or make solution flow out exchange column according to the ion-exchange performance.
Described resin scrubbing tower is a cylindrical shell, and the cumulative volume of cylindrical shell volume and ion exchange column is close, and the resin of finishing ion exchange process is entered by cylindrical shell top.Cleaning solution is entered by the cylindrical shell bottom.Resin through washing is sent by the outlet of cylindrical shell bottom, returns ion exchange column.
The beneficial effects of the utility model are: this device can take full advantage of the exchange capacity of resin, and resin demand is few, the utilization rate height, and cost is low, and compact conformation is simple to operate, is easy to control.This device can guarantee that the resin that absorption can be finished within a short period of time discharges in ion exchange process, guaranteed the unimpeded of bed, and can not cause its exchange capacity to descend.This device can distribute ion exchange column according to the progress of ion-exchange, and there is a taphole at the taphole place above each ion exchange column, if reach desired concn, then solution can be flowed out by outlet, does not enter down one deck.This device can be regulated the rate travel of resin automatically according to the concentration of solution, and the exchange capacity of resin can be fully used, and resin and usage ratio of equipment all increase, and have saved investment.The resin that washing is finished returns ion exchange column to be continued to utilize, and the consumption of resin can significantly reduce, and has reduced labour intensity.

The specific embodiment
Below in conjunction with accompanying drawing a kind of ion interchange unit of the utility model is introduced more in detail.
The utility model mainly comprises ion exchange system, ion-cleaning system.Wherein ion exchange system is that 2～5 ion exchange columns 1 are formed, and wherein ion exchange column is diameter 100～400mm, the cylinder of high 500～2000mm, between the two adjacent exchange columns for being connected in series.The resin outlet of ion-exchange column bottom links to each other with the resin scrubbing tower.Resin scrubbing tower 2 is one simplified, and the cumulative volume of cylindrical shell volume and ion exchange column is close, and the resin of finishing ion exchange process is entered by simplified top.Cleaning solution is entered by the cylindrical shell bottom.Resin through washing is sent by the outlet of cylindrical shell bottom, returns ion exchange column.
After in ion exchange column, being full of resin and compacting, material liquid is entered from the ion-exchange column bottom by material liquid entrance a, carry out ion-exchange with resin, solution is flowed out by top exit and enters next ion exchange column, successively with ion exchange column in ion carry out ion-exchange, flow out finally by taphole b.Resin in the ion exchange column slowly moves down, the resin of bottom flows out exchange column and enters scrubbing tower by resin entrance f, cleaning solution by tower bottom cleaning solution entrance c enter, cleaning solution outlet d flows out, the resin that washing is finished is flowed out by resin outlet e and enters ion exchange column again.
Located a taphole above each ion exchange column, if reach desired concn, then solution can directly be flowed out by this outlet, does not enter down one deck.Equipment can carry out adsorption process flexibly, has reduced ion-exchange time thus, improves device efficiency.
At resin exit, ion-exchange column bottom mounted valve, can regulate the translational speed of resin as required, resin is fully used, and can guarantee that the resin that absorption can be finished within a short period of time discharges, guarantee the unimpeded of bed, and can not cause its exchange capacity to descend.
It should be noted that at last: above embodiment is only in order to illustrate the utility model and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to the above embodiments,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the middle of the claim scope of the present utility model.
