[0044] 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.

[0045] 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.

[0046] Please refer to Figure 1 The present invention provides a uranium extraction material elution and regeneration device from seawater, comprising an elution and regeneration tank 1, an eluent collecting flow path 2 and a regeneration liquid collecting flow path 3. At least two spacer areas 11 are arranged inside the elution and regeneration tank 1, and adjacent spacer areas 11 are interconnected. The fiber materials after uranium adsorption are placed in the spacer areas 11 at intervals.

[0047] 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.

[0048] Based on this, the present invention sets at least two spacing areas 11 in the elution regeneration tank 1, and the fiber materials can be placed in the spacing areas 11 at intervals for spacing.

[0049] The inlet and outlet ends of the eluent collecting flow path 2 are respectively connected to the elution regeneration tank 1 . The eluent collecting flow path 2 is provided with at least two parallel eluent collecting tanks 21 to collect eluents of different concentrations flowing through the spacer 11 .

[0050] 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.

[0051] 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.

[0052] 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 flowing through the interval area 11 for treatment and discharge or return to the elution regeneration tank 1 for reuse.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] Please refer to Figure 2 and Figure 3 An inlet 15 is provided on the elution regeneration tank 1, and the eluent or regeneration liquid enters the elution regeneration tank 1 through the inlet 15; a plurality of partitions 111 are provided in the elution regeneration tank 1, and the partitions 111 divide the interior of the elution regeneration tank 1 into a plurality of partition areas 11; at least one flow hole 112 is provided on the partition 111.

[0057] Please refer to 1 and Figure 2 The top of the elution regeneration tank 1 can be designed to be open, and the open opening corresponds to the inlet 15. The eluent or regeneration liquid can be injected into the elution regeneration tank 1 from the top opening. At the same time, the inlet 15 also serves as the discharge port of the eluent or regeneration liquid.

[0058] In some other embodiments, the inlet 15 may also be opened at other positions, such as the side of the elution regeneration tank 1, and the specific position is not limited here.

[0059] Optionally, the plurality of partitions 111 are arranged in a honeycomb shape in the elution regeneration tank 1 .

[0060] The multiple honeycomb-shaped spacing areas 11 can place fiber materials at intervals, which is beneficial to increase the amount of fiber materials placed, thereby improving the utilization rate of the elution and regeneration tank 1.

[0061] It should be noted that the partition 111 is provided with at least two flow holes 112 at intervals along the elution regeneration tank 1. Moreover, the multiple partitions 111 can be integrally formed into a honeycomb shape and then directly placed in the elution regeneration tank 1; or, one end of the honeycomb partition 111 is clamped or welded to the bottom of the elution regeneration tank 1, etc., which is not limited here.

[0062] Thus, the eluent or regeneration liquid can flow through each spacing zone 11 in sequence and fully contact with the fiber material.

[0063] Furthermore, a rotating mechanism 14 is provided at the bottom of the elution and regeneration tank 1 for driving the elution and regeneration tank 1 to rotate.

[0064] Rotating the elution regeneration tank 1 during the elution or regeneration process is beneficial to increasing the flow rate of the eluent or regeneration liquid in the spacing zone 11, thereby increasing the contact probability and contact amount between the eluent or regeneration liquid and the fiber material, which is beneficial to improving the elution or regeneration efficiency.

[0065] Please continue to refer to Figure 1 and Figure 2 The elution regeneration tank 1 is provided with at least one liquid inlet 12 and at least one liquid outlet 13 ; the liquid inlet 12 and the liquid outlet 13 are arranged on opposite sides of the elution regeneration tank 1 .

[0066] For example, the liquid inlet 12 is located at the top of the elution regeneration tank 1 or at a side portion close to the top; the liquid outlet 13 is opened at the bottom of the elution regeneration tank 1 .

[0067] Alternatively, the liquid inlet 12 and the liquid outlet 13 are opened on the side of the elution regeneration tank 1 and are arranged correspondingly, thereby improving the flow path of the eluent or regeneration liquid in the elution regeneration tank, so that the eluent or regeneration liquid is fully in contact with the fiber material.

[0068] The liquid inlet 12 and the liquid outlet 13 are disposed on opposite sides of the elution regeneration tank 1, thereby allowing the eluent or regeneration liquid to flow through each spacer 11 to a greater extent, thereby improving the elution efficiency or regeneration efficiency.

[0069] It can be seen that a liquid inlet 12 and a liquid outlet 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,

[0070] Two liquid inlets 12 and two liquid outlets 13 may also be provided 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 liquid inlet 12 and a liquid outlet 13, both methods are acceptable and are not limited here.

[0071] Alternatively, the inlet 15 at the top of the elution regeneration tank 1 can be used as the liquid inlet 12 and the liquid outlet 13, that is, the inlet 15, the liquid inlet 12 and the liquid outlet 13 are the same opening. The above three methods are all possible and are not limited here.

[0072] Specifically, one end of the eluent collecting flow path 2 is connected to the liquid outlet 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 liquid inlet 12.

[0073] The two first regulating valves 221 are arranged on opposite sides of the eluent collecting tank 21. By controlling the on and off of the first regulating valves 221, the flow direction of the eluent in the eluent collecting tank 21 can be controlled, so that the high-concentration eluent can flow to the uranium recovery section, and the medium and low-concentration eluent can return to the elution regeneration tank 1 for reuse.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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 .

[0079] 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.

[0080] 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.

[0081] 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.

[0082] Please continue to refer to Figure 1 One end of the regeneration liquid collecting flow path 3 is connected to the liquid outlet 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 liquid inlet 12.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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 .

[0089] 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.

[0090] 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.

[0091] Before replacing the fiber material, the fiber material needs to be dehydrated, and the process is: turn on the rotating mechanism 14 to dehydrate the fiber material by centrifugal force.

[0092] In summary, in the elution and regeneration device for extracting uranium from seawater of the present invention, a partition area 11 is provided in the elution and regeneration tank 1, and the fiber materials adsorbing uranium are respectively arranged in the partition area 11 for separation, thereby avoiding disturbance of the fiber materials during the elution, regeneration and dehydration processes, and reducing mechanical damage to the fiber materials.

[0093] At least two parallel eluent collecting tanks 21 are provided on the eluent collecting flow path 2. The eluent can be processed according to concentration. The eluent with higher uranium concentration can directly enter the uranium recovery section, while the eluent with lower uranium concentration can be repeatedly eluted, so as to improve the elution efficiency of the eluent and reduce the solution processing volume of the uranium recovery section.

[0094] At least two parallel regeneration liquid collecting tanks 31 are arranged on the regeneration liquid collecting flow path 3. The regeneration liquid can be treated according to concentration. The regeneration liquid with low concentration can be discharged after being treated to meet the standards, and the regeneration liquid with higher concentration can be returned to the elution regeneration tank 1 for reuse, thereby improving the utilization rate of the regeneration liquid while ensuring the regeneration effect.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can also be a mechanical connection.
