Description
Technical field
The present invention relates to a kind of ion-exchange unit for radioactivity field, particularly a kind of radioactive shield mixed ion exchanger.
Background technology
Mixed ion exchanger be anion and cation exchange resin by a certain percentage mixed packing in same container, the equipment that the yin, yang ion in convection cell exchanges simultaneously, removes.
Because yin, yang Ar ion mixing is seated in same ion-exchanger, thereby mixed ion exchanger is equivalent to by the countless yin, yang ion-exchangers multiple bed of the multi-stage type that forms that is staggered, yin, yang ion evenly mixes therein and carries out permutoid reaction simultaneously, eliminate the impact of gegenion, made exchange carry out very thoroughly.
In many Application Areass of mixed ion exchanger, remove the corrosion product of water intermediate ion state, the purification object that reaches water quality is one of its topmost application.
Although there is above-mentioned advantage; but in the time that mixed ion exchanger is applied to radioactivity field; for example, while removing the ionic condition corrosion product having in radioactive light-water or heavy water; it cannot use owing to there is no shielding protection function, and does not find to be applicable at present the mixed ion exchanger in radioactivity field.
Summary of the invention
For solving the problem that is not applicable to the mixed ion exchanger in radioactivity field in prior art, the invention provides a kind of radioactive shield mixed ion exchanger.
This radioactive shield mixed ion exchanger comprises ion exchange column and screen layer; Described screen layer comprises base and lead shielding layer, and described ion exchange column is arranged on base; Lead shielding layer is arranged at ion exchange column outside, and is connected with base by flange, to realize the detachable of lead shielding layer; Ion exchange column upper cover is provided with liquid-inlet pipe, and lower cover is provided with drain pipe and resin fills comb, and described liquid-inlet pipe, drain pipe and resin fill comb and all lead to outside by the default duct on base.
Described lead shielding layer is preferably fills with lead and makes in ghost.
Described base is preferably stainless steel base.
Install for ease of centering, corresponding gap and boss are set for preferred at ion exchange column and base matching part.
Described lead shielding layer outside can also be provided with hanging support, in installation, movement, transport and maintenance process, can play a supporting role.
Radioactive shield mixed ion exchanger of the present invention can be realized the purifying treatment of radioactive liquid waste under the condition that meets radioactive shield protection; not only can entirety storage, but also can store separately inner vessels; and there is waterpower and carry the function of spent resin; it is simple in structure, installation is easy, maintenance is convenient; the lead shielding layer adopting is detachable, can Reusability.
Brief description of the drawings
The main sectional view of Fig. 1 radioactive shield mixed ion exchanger of the present invention.
Fig. 2 radioactive shield mixed ion exchanger of the present invention sectional view.
Reference numeral: 1. base, 2. lower cover, 3. ion exchange column, 4. lead shielding layer, 5. upper cover, 6. hanging support, 7. liquid-inlet pipe, 8. resin fills comb, 9. drain pipe.
Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention are described further.
Embodiment
As shown in Figure 1, 2, radioactive shield mixed ion exchanger of the present invention fills comb 8 by resin and is filled with and discharges anion and cation exchange resin.
When use, radioactive liquid waste injects ion exchange column 3 by liquid-inlet pipe 7, removes yin, yang ionic impurity wherein by yin, yang ion-exchange, and the liquid after purification is discharged by drain pipe 9.
After the anion and cation exchange resin of radioactive shield mixed ion exchanger lost efficacy, lead shielding layer 4 can be disassembled from base 1, in order to using next time, rest part can be used as radwaste and carries out stage treatment or overall disposal.
At present, radioactive shield mixed ion exchanger of the present invention has been successfully applied to light-water/heavy water scavenging process of CSNS engineering target station water cooling system, and has obtained satisfied effect.
