[0043] The present invention is further described below in conjunction with specific embodiments and drawings. More details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can obviously be implemented in a variety of other ways different from the description herein. Those skilled in the art can make similar generalizations and deductions based on actual application situations without violating the connotation of the present invention. Therefore, the protection scope of the present invention should not be limited by the content of this specific embodiment.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned figure descriptions and any variations thereof are intended to cover non-exclusive inclusions.

[0045] Please refer to Figures 1 to 4The present invention provides a fibrous seawater uranium extraction material elution and regeneration device, comprising an elution and regeneration tank 1, an eluent collecting flow path 2 and a regeneration liquid collecting flow path 3. A material hanging bracket 11 is provided on the top of the elution and regeneration tank 1. The fiber materials after uranium adsorption are hung on the material hanging bracket 11 in single strands at intervals. The height of the material hanging bracket 11 is adjustable.

[0046] At present, the seawater uranium extraction test materials are amidoxime-based fibrous materials. The fibrous seawater uranium extraction materials that adsorb uranium from real sea areas need to be fully in contact with eluent and regeneration liquid. The seawater uranium extraction materials have the characteristics of low mechanical strength, fibrous material, easy entanglement and knotting, and relatively low reuse rate.

[0047] Based on this, the present invention divides the fiber material into single strands and hangs them on a material hanging bracket 11. One end of the material hanging bracket 11 is arranged on the top of the elution regeneration tank 1 through a lifting component. The fiber material and the material hanging bracket 11 can be connected by a detachable buckle.

[0048] For example, a crossbeam is arranged on the top of the elution regeneration tank 1, and the material hanging bracket 11 is arranged on the crossbeam through a liftable component. The specific installation form of the material hanging bracket 11 is not limited here.

[0049] When the adsorbent material needs to be in contact with the eluent, it can be lowered by the elevating component until it is in contact with the solution. When the solution needs to be replaced, the adsorbent material can be lifted by the elevating component.

[0050] The inlet and outlet ends of the eluent collecting flow path 2 are respectively connected to the elution regeneration tank 1 , and at least two parallel eluent collecting tanks 21 are provided on the eluent collecting flow path 2 to collect eluents of different concentrations.

[0051] That is, since the subsequent process needs to recover the eluted uranium from the eluent, the uranium concentration of the eluent is increased and the volume of the solution is reduced, thereby improving the processing efficiency of the uranium recovery process.

[0052] The present invention is provided with at least two elution regeneration tanks 1, and the elution regeneration tanks 1 can be divided into A, B, C and the like according to the concentration of recovered uranium, so that the eluent with high uranium concentration can directly enter the uranium recovery process section, and the uranium-containing eluent in the medium concentration and low concentration sections can be returned to the elution regeneration tank 1 for repeated elution, so as to improve the elution efficiency of the eluent and reduce the solution processing volume of the uranium recovery section.

[0053] Specifically, the inlet and outlet ends of the regeneration liquid collecting flow path 3 are respectively connected to the elution regeneration tank 1, and at least two parallel regeneration liquid collecting tanks 31 are provided on the regeneration liquid collecting flow path 3. The regeneration liquid collecting tanks 31 are used to collect regeneration liquids of different concentrations for treatment and discharge or return to the elution regeneration tank 1 for reuse.

[0054] It can be seen that at least two parallel regeneration liquid collection tanks 31 are set, and the regeneration liquid in the low-concentration regeneration liquid collection tank 31 is discharged after being treated to meet the standards, and the regeneration liquid in the medium- and high-concentration regeneration liquid collection tanks 31 can be returned to the elution regeneration tank 1 for reuse, so as to improve the utilization rate of the regeneration liquid while ensuring the regeneration effect. The regeneration liquid can be treated as a secondary pollutant and then discharged.

[0055] Compared with the design of adding the same volume of regeneration liquid in a single batch, the recycling and batch collection of the regeneration liquid can reduce the discharge of the regeneration liquid after use by nearly 60%, thereby greatly improving the environmental friendliness.

[0056] Moreover, the amount of uranium-containing solution treated in the subsequent uranium processing section was reduced by nearly 60%, and the uranium concentration in the uranium-containing solution was increased by at least three times.

[0057] In one embodiment, an inlet 18 is provided on the elution regeneration tank 1, and the eluent or regeneration liquid enters the elution regeneration tank 1 through the inlet 18. The inlet 18 is used to inject the eluent or regeneration liquid into the elution regeneration tank 1.

[0058] Specifically, the top of the elution regeneration tank 1 is designed to be open, and the open opening corresponds to the inlet 18. The eluent or regeneration liquid can be injected into the elution regeneration tank 1 from the top, and the inlet 18 also serves as the discharge port of the eluent or regeneration liquid.

[0059] In some other embodiments, the entrance 18 may also be opened at other positions, which is not limited here.

[0060] Reference Figure 3 A plurality of mounting positions 111 are provided on the material hanging bracket 11, and each mounting position 111 is mounted with a single strand of fiber material by snap-fitting.

[0061] Each installation position 111 can be detachably mounted with fiber material by means of buckles.

[0062] Optionally, the material hanging bracket 11 includes multiple layers of circular rings, each of which is circumferentially provided with a plurality of mounting positions 111 , and adjacent mounting positions 111 are spaced apart.

[0063] In some other implementations, the material hanging bracket 11 may also be configured to have other shapes, which are not limited here.

[0064] Please refer to Figure 1 and Figure 2The elution regeneration tank 1 is provided with at least one first liquid inlet 12 and at least one second liquid inlet 13; a partition 14 is provided on the inner bottom surface of the elution regeneration tank 1, one end of the partition 14 is connected to the side wall of the elution regeneration tank 1 and divides the elution regeneration tank 1 into a first chamber 15 and a second chamber 16, and the first chamber 15 and the second chamber 16 are connected at a side away from the connection end of the partition 14 and the side wall of the elution regeneration tank 1; the first liquid inlet 12 is connected to the first chamber 15, and the second liquid inlet 13 is connected to the second chamber 16.

[0065] It can be seen that a first liquid inlet 12 and a second liquid inlet 13 can be provided on the elution regeneration tank 1, and the eluent collection flow path 2 and the regeneration liquid collection flow path 3 can be connected and used in sequence, thereby satisfying the operation of the eluent and regeneration liquid circulation flow paths. Or,

[0066] Two first liquid inlets 12 and two second liquid inlets 13 can be set on the elution regeneration tank 1, and the eluent collection flow path 2 and the regeneration liquid collection flow path 3 are each independently connected to a first liquid inlet 12 and a second liquid inlet 13. Both methods are acceptable and are not limited here.

[0067] Or please refer to Figure 4 The inlet 18 at the top of the elution regeneration tank 1 can be used as the first liquid inlet 12 and the second liquid inlet 13, that is, the inlet 18, the first liquid inlet 12 and the second liquid inlet 13 are the same opening. The above three methods are all possible and are not limited here.

[0068] In order to ensure full contact between the adsorption material and the eluent or regeneration liquid, promote the uniform diffusion of the eluent or regeneration liquid, and prevent the fiber material from being disturbed and entangled during the mixing of the eluent or regeneration liquid, which may lead to material damage and difficulty in subsequent reuse, the eluent or regeneration liquid is mixed evenly by using the flow of water of the eluent or regeneration liquid.

[0069] Specifically, a partition 14 is arranged from the center to the edge of the elution regeneration tank 1, and the partition 14 divides the elution regeneration tank 1 into a first chamber 15 and a second chamber 16, so that the flow distance of the water flow can be increased, the mixing is more uniform, and the direction of the water flow can be achieved by switching the direction of the first liquid inlet 12 and the second liquid inlet 13.

[0070] In one embodiment, one end of the eluent collecting flow path 2 is connected to the second liquid inlet 13 and is divided into at least two first branches 22, each first branch 22 is provided with an eluent collecting tank 21, and a first regulating valve 221 is provided on each opposite side of the eluent collecting tank 21; the other end of the eluent collecting flow path 2 is connected to the first liquid inlet 12.

[0071] The two first regulating valves 221 are disposed on opposite sides of the eluent collecting tank 21, thereby controlling the flow direction of the eluent in the eluent collecting tank 21. For example, the eluent with high concentration can flow to the uranium recovery section, while the eluent with medium and low concentration can flow back to the elution regeneration tank 1 for reuse.

[0072] Furthermore, the eluent collecting flow path 2 is provided with a second regulating valve 23 upstream of the eluent collecting tank 21; the eluent collecting flow path 2 is provided with an eluent filter 24 and an eluent pump 25 downstream of the eluent collecting tank 21, which are respectively used for filtering and transporting the eluent; the eluent collecting flow path 2 is also provided with a third regulating valve 26 between the eluent filter 24 and the eluent collecting tank 21.

[0073] The second regulating valve 23 can adjust the flow rate of the eluent flowing out of the elution regeneration tank 1. The specific flow rate can be adjusted according to actual needs and is not limited here.

[0074] The eluent filter 24 can filter impurities in the eluent of medium and low concentrations, and the eluent pump 25 is used to provide power for conveying the liquid from the eluent collecting tank 21 to the elution regeneration tank 1.

[0075] The third regulating valve 26 is used to control the flow direction of the eluent discharged from the eluent collecting tank 21, for example, it can flow to the elution regeneration tank 1, or it can flow to the uranium recovery section.

[0076] Specifically, a uranium recovery flow path 27 is further provided on the eluent collection flow path 2 for collecting eluent with a high uranium content, and a fourth regulating valve 271 is provided on the uranium recovery flow path 27 .

[0077] Here, three eluent collecting tanks 21 are taken as an example for description, namely, the eluent collecting tank 21A, the eluent collecting tank 21B, and the eluent collecting tank 21C.

[0078] In actual application, a certain amount of eluent is first introduced into the elution regeneration tank 1, and discharged into the eluent collecting tank 21A after elution; then a certain amount of eluent is introduced into the elution regeneration tank 1 again, and discharged into the eluent collecting tank 21B after elution. Secondly, a certain amount of eluent is introduced into the elution regeneration tank 1 again, and discharged into the eluent collecting tank 21C after elution. At this time, the uranium concentration of the eluent in the eluent collecting tank 21A, the eluent collecting tank 21B, and the eluent collecting tank 21C decreases in sequence, and the eluent in the eluent collecting tank 21A has the highest uranium concentration, which can be directly discharged to the uranium recovery section. The uranium concentration of the eluent in the eluent collecting tank 21B and the eluent collecting tank 21C is sampled and tested. If the concentration is too low, it is returned to the elution regeneration tank 1 for repeated cleaning in sequence.

[0079] It can be seen that if the uranium concentration of the eluent in the eluent collecting tank 21C is very low and the concentration does not change much after repeated elution, new fiber material can be replaced and then injected into the eluent collecting tank 21C as a new eluent for elution.

[0080] Please continue to refer to Figure 1 One end of the regeneration liquid collecting flow path 3 is connected to the second liquid inlet 13 and is divided into at least two second branches 32. Each second branch 32 is provided with a regeneration liquid collecting tank 31, and a fifth regulating valve 321 is provided on each opposite side of the regeneration liquid collecting tank 31; the other end of the regeneration liquid collecting tank 31 is connected to the first liquid inlet 12.

[0081] The number of the regeneration liquid collecting tanks 31 can be two, three, or more, which is not limited here. Here, three are taken as an example for description, which is not limited here.

[0082] After the elution is completed, the elution regeneration tank 1 is in a liquid-free state and then the regeneration liquid is injected into the elution regeneration tank 1. Each time the regeneration liquid is circulated, it can be discharged to different regeneration liquid collection tanks 31 in turn, and the concentration of the regeneration liquid is sampled and tested. If the concentration is too high, it is returned to the elution regeneration tank 1 for further treatment. If the concentration is too low, it is discharged after treatment.

[0083] Compared with the design of adding the same volume of regeneration liquid once, the recycling and batch collection of the regeneration liquid can reduce the discharge of the regeneration liquid after use by nearly 60%, which can greatly improve the environmental friendliness.

[0084] Furthermore, the regeneration liquid collecting flow path 3 is provided with a sixth regulating valve 33 upstream of the regeneration liquid collecting tank 31; the regeneration liquid collecting flow path 3 is provided with a regeneration liquid filter 34 and a regeneration liquid pump 35 downstream of the regeneration liquid collecting tank 31, which are used for filtering and transporting the regeneration liquid respectively.

[0085] The regeneration liquid filter 34 is used to filter impurities, and the regeneration liquid pump 35 is used to provide the power for conveying the regeneration liquid.

[0086] Furthermore, a discharge flow path 36 is provided on the regeneration liquid collecting flow path 3 for discharging low-concentration regeneration liquid; a seventh regulating valve 361 is provided on the discharge flow path 36 .

[0087] When the concentration of the regeneration liquid in the regeneration liquid collecting tank 31 is lower than the target value, the seventh regulating valve 361 can be opened to discharge the regeneration liquid.

[0088] Since the adsorption sites of the seawater uranium extraction material are occupied by the solvent during the elution and regeneration process, it is not conducive to the seawater uranium extraction material to adsorb uranium again. Therefore, in order to improve the secondary adsorption capacity of the material, the material needs to be dehydrated.

[0089] In one embodiment, an air inlet 17 is provided on the elution and regeneration tank 1 to dehydrate the fiber material when the liquid in the elution and regeneration tank 1 is emptied.

[0090] After the solution in the elution regeneration tank 1 is drained, air at 5-60° C. can be filled into the elution regeneration tank 1 through the air inlet 17, and the air flow rate is controlled at 0.5-10 BV / min, where BV is the volume of the elution regeneration tank 1. The air inlet 17 is opened at the bottom of the elution regeneration tank 1, and the number can be three, six, etc., which is not limited here.

[0091] The air entering through the air inlet 17 is discharged from the inlet port 18 to the outside of the elution regeneration tank 1, thereby performing dehydration.

[0092] In summary, the elution and regeneration device provided in the present invention integrates elution, regeneration and dehydration, which can avoid disturbance of fiber materials during elution, regeneration and dehydration, and reduce the mechanical damage to the materials.

[0093] Moreover, the eluent or regenerated liquid can be received and processed in sections and reused repeatedly, which can effectively improve the utilization efficiency of the eluent or regenerated liquid. The amount of uranium-containing solution treated in the subsequent uranium recovery section is reduced by 60%, and the uranium concentration in the uranium-containing solution is increased three times. The recycling and batch collection of the regenerated liquid can reduce the emission of the regenerated liquid after use by 60%, significantly improving environmental friendliness.
