[0002] With the expansion of industrial activities and the improvement of environmental standards, traditional water treatment methods face many challenges. Ion adsorption exchange technology has attracted widespread attention due to its high efficiency. Ion exchange technology is a method of removing compounds from water by exchanging ions in aqueous solutions. Ion exchange resins are used to capture specific cations and anions, thereby effectively removing heavy metals, hardness ions and other harmful chemicals from water. Compared with traditional physical and chemical methods, ion exchange can achieve higher water treatment effects with lower energy consumption and chemical consumption. Ion exchange technology has excellent reuse and regeneration capabilities. Through resin regeneration, the used resin can restore its exchange capacity and then be used again in the water treatment process, which not only improves the efficiency of water treatment, but also provides industrial enterprises with a cost-effective solution to cope with increasingly stringent environmental standards.

[0040] The technical solution of the present invention has the following significant beneficial effects:

[0041] 1. After the sewage is output from the end of the first port, the sewage flows in a swirling flow along the inner wall of the cylinder. The water flow descends in a spiral, and the sewage is fully contacted and adsorbed with the ion exchange resin on the side wall of the cylinder during the spiral descent. The adsorbed sewage is discharged from the second port. The above method greatly increases the degree of contact between the sewage and the ion exchange resin. After the sewage is output from the third port into the accommodation space, the sewage is contacted and adsorbed with the ion exchange resin in the accommodation space, and the sewage flows downward, and finally the adsorbed sewage is discharged from the fourth port. In the present application, the two methods of direct contact and adsorption of sewage with the ion exchange resin and contact and adsorption with the ion exchange resin through the swirling flow of the cylinder are combined to make the adsorption more sufficient.

[0042] 2.

After the regenerated water input from the second port enters the cylinder, the regenerated water swirls along the inner side wall of the cylinder, and the water flow rises in a spiral. During the spiral rise of the regenerated water, it fully contacts the ion exchange resin at the side wall of the cylinder to regenerate the ion exchange resin. This part of the regenerated water is discharged from the first port. The above method greatly increases the degree of contact between the regenerated water and the ion exchange resin, which is conducive to the complete regeneration of the resin. After the regenerated water input from the fourth port enters the accommodating space, the regenerated water contacts and adsorbs the ion exchange resin in the accommodating space, and the regenerated water flows upward, and finally the regenerated water is discharged from the third port. In this application, the two methods of direct contact regeneration between the regenerated water and the ion exchange resin and contact regeneration with the ion exchange resin through the cylinder for swirl flow are combined, which is conducive to the complete regeneration of the resin. In particular, from the small section at the lower end of the cylinder to the large section at the upper end, the water pressure and the swirl force of the cylinder can be fully utilized to fully reversely regenerate the ion exchange tree.

[0051] In order to solve the problem that wastewater is prone to incomplete contact adsorption and unsaturated adsorption of adsorbent materials when reacting with adsorbent materials in adsorption columns, an ion adsorption exchange device is proposed in the present application. Figure 1 FIG. 1 is a schematic diagram of the structure of the ion adsorption exchange device in an embodiment of the present invention. Figure 1 As shown, the ion adsorption exchange device may include: a tank body 2; and a cylinder body 1 disposed in the tank body 2. The tank body 2 is disposed in a vertical direction. The tank body 2 has a first port 21, a second port 22, a third port 23, and a fourth port 24.

[0052] The cylinder 1 extends in the vertical direction. The cylinder 1 is made of ion exchange resin. The radial dimension of the cylinder 1 gradually decreases from top to bottom. The upper end of the cylinder 1 is sealed with the upper end surface of the tank 2, and the lower end of the cylinder 1 is sealed with the lower end surface of the tank 2.

[0053] Furthermore, the direction of the end of the second port 22 is perpendicular to the radius of the cylinder 1 , so that the output liquid flows in a swirling flow along the inner wall of the cylinder 1 .

[0054] An accommodating space is formed outside the outer wall of the cylinder 1 inside the tank body 2. The first port 21 is located on the upper end surface of the tank body 2 and is connected to the cylinder 1. The direction of the end of the first port 21 is perpendicular to the radius of the cylinder 1 so that the output liquid flows in a swirling flow along the inner wall of the cylinder 1.

[0055] The second port 22 is located at the lower end of the tank 2 and communicates with the cylinder 1, the third port 23 is located at the upper end of the tank 2 and communicates with the accommodation space, and the fourth port 24 is located at the lower end of the tank 2 and communicates with the accommodation space. The accommodation space is used to fill the ion exchange resin 3.

[0056] Preferably, the horizontal cross-section of the cylinder 1 may be circular or approximately circular in shape, which can greatly reduce the resistance to the swirling flow of the liquid along the inner wall of the cylinder 1 and help increase the flow rate of the liquid.

[0057] As a feasible method, in order to make the sewage or recycled water inputted into the accommodation space from the third port 23 and the fourth port 24 more dispersed, so that the above liquid can flow to various positions in the circumferential direction of the accommodation space more evenly, there are at least two third ports 23, and the third ports 23 are distributed circumferentially around the axis of the tank body 2. There are at least two fourth ports 24, and the fourth ports 24 are distributed circumferentially around the axis of the tank body 2.

[0058] As a feasible method, the ion adsorption exchange device has a sewage treatment state. In the sewage treatment state, the first port 21 and the third port 23 are used to input sewage; the second port 22 is used to discharge the sewage adsorbed in the cylinder 1, and the fourth port 24 is used to discharge the sewage adsorbed in the accommodating space.

[0059] As a feasible method, the ion adsorption exchange device also has a regeneration processing state. In the regeneration processing state, the second port 22 and the fourth port 24 are used to input regeneration water that can regenerate the ion exchange resin 3, the first port 21 is used to discharge the regeneration water in the cylinder 1, and the third port 23 is used to discharge the regeneration water in the accommodation space. Through the above process, the ion exchange resin 3 in the accommodation space can be regenerated.

[0060] As a feasible method, the ion adsorption exchange device also has a state in which sewage treatment and regeneration treatment are carried out simultaneously. In this state, the first port 21 is used to input sewage; the second port 22 is used to discharge the sewage adsorbed in the cylinder 1, the fourth port 24 is used to input regenerated water that can regenerate the ion exchange resin 3, and the third port 23 is used to discharge the regenerated water in the accommodation space. In this way, sewage adsorption treatment and regeneration treatment of the ion exchange resin 3 and the cylinder 1 can be carried out simultaneously in one ion adsorption exchange device.

[0061] In order to enable the fluid to maintain a sufficient speed in the vortex flow on the inner wall of the cylinder 1, the inclination angle of the side wall of the cylinder 1 can be generally between 15 degrees and 30 degrees, otherwise the fluid may flow directly downward instead of vortexing, so that the degree to which the fluid contacts the ion exchange resin on the side wall of the cylinder 1 will be greatly reduced.

[0062] Preferably, the cylinder 1 may be located at the center of the tank 2. This can prevent the ion exchange resin 3 in the accommodating space from being overused and being saturated with adsorption in advance.

[0063] The first port 21 can be connected to the first branch pipe 41, and the first branch pipe 41 is provided with a first valve 43. The third port 23 can be connected to the third branch pipe 42, and the third branch pipe 42 is provided with a third valve 44. The second port 22 can be connected to the second branch pipe 51, and the second branch pipe 51 is provided with a second valve 53. The fourth port 24 can be connected to the fourth branch pipe 52, and the fourth branch pipe 52 is provided with a fourth valve 54. The opening and closing of each port can be controlled in the above manner.

[0064] Further, the ion adsorption exchange device includes: a first main pipeline 4, a first port 21 is connected to the first main pipeline 4 through a first branch pipeline 41, a third port 23 is connected to the first main pipeline 4 through a third branch pipeline 42, and a first main valve 45 is provided on the first main pipeline 4; a second main pipeline 5, a second port 22 is connected to the second main pipeline 5 through a second branch pipeline 51, a fourth port 24 is connected to the second main pipeline 5 through a fourth branch pipeline 52, and a second main valve 55 is provided on the second main pipeline 5. The main valve can control the connection and disconnection of sewage and the ion adsorption exchange device, and the connection and disconnection of recycled water and the ion adsorption exchange device.

[0065] An upper inspection hole 25 may be provided at the upper end surface of the tank body 2, and a removable upper sealing cover plate 26 may be installed at the upper inspection hole 25. The upper sealing cover plate 26 may be connected to the upper end surface of the tank body 2 by multiple bolts to achieve removability. A lower inspection hole 27 is provided at the lower end surface of the tank body 2, and a removable lower sealing cover plate 28 is installed at the lower inspection hole 27. The lower sealing cover plate 28 may be connected to the lower end surface of the tank body 2 by multiple bolts to achieve removability.

[0066] An observation hole 29 may be provided on the side wall of the tank body 2, and a transparent member 210 is provided at the observation hole 29 to seal the observation hole 29. Through the transparent member 210, the operator can observe the state inside the tank body 2 from the outside, such as the state of the ion exchange resin 3. Correspondingly, an inspection platform 6 may be provided at the top and side wall of the tank body 2 so that the operator can operate at the observation hole 29 and the upper inspection hole 25.

[0067] Preferably, the tank body 2 can be made of glass fiber reinforced plastic material, which has the characteristics of high strength, low density and corrosion resistance.

[0068] After the sewage is output from the end of the first port 21, the sewage flows in a swirling flow along the inner wall of the cylinder 1. The water flow descends in a spiral, and the sewage fully contacts and adsorbs the ion exchange resin on the side wall of the cylinder 1 during the spiral descent. The partially adsorbed sewage is discharged from the second port 22. The above method greatly increases the degree of contact between the sewage and the ion exchange resin of the cylinder 1. After the sewage is output from the third port 23 into the accommodation space, the sewage contacts and adsorbs the ion exchange resin 3 in the accommodation space, and the sewage flows downward. Finally, the partially adsorbed sewage is discharged from the fourth port 24. In the present application, the two methods of direct contact and adsorption of the sewage with the ion exchange resin 3 and contact and adsorption with the ion exchange resin of the cylinder 1 by swirling flow through the cylinder 1 are combined to make the adsorption more sufficient.

[0069] When it is necessary to regenerate the ion exchange resin 3 and the cylinder 1 in the accommodating space of the ion adsorption exchange device, the regenerated water can be input from the second port 22 and the fourth port 24 at the same time. After the regenerated water input from the second port 22 enters the cylinder 1, the regenerated water swirls along the inner wall of the cylinder 1, and the water flow rises in a spiral. During the spiral rise of the regenerated water, it fully contacts the ion exchange resin at the side wall of the cylinder 1 to regenerate the ion exchange resin. This part of the regenerated water is discharged from the first port 21. The above method greatly increases the degree of contact between the regenerated water and the ion exchange resin, which is conducive to the complete regeneration of the resin. After the regenerated water input from the fourth port 24 enters the accommodating space, the regenerated water contacts and adsorbs the ion exchange resin 3 in the accommodating space, and the regenerated water flows upward, and finally the regenerated water is discharged from the third port 23. In the present application, the two methods of direct contact regeneration between the regenerated water and the ion exchange resin 3 and contact regeneration with the ion exchange resin of the cylinder 1 by swirl flow through the cylinder 1 are combined, which is conducive to the complete regeneration of the resin. Especially from the small section at the lower end to the large section at the upper end of the cylinder 1, the water pressure and the cyclonic force of the cylinder 1 can be fully utilized to fully reversely regenerate the ion exchange tree.

[0070] The present application also proposes an operation method using the above ion adsorption exchange device, which may include: inputting sewage into the cylinder 1 through the first port 21, and discharging the adsorbed sewage in the cylinder 1 through the second port 22; at the same time, inputting regenerated water into the accommodation space through the fourth port 24, and discharging the regenerated water in the accommodation space through the third port 23. This method can realize the simultaneous sewage adsorption treatment and the regeneration treatment of the ion exchange resin 3 and the cylinder 1 in one ion adsorption exchange device.

[0071] In this application, an ion adsorption exchange system is also proposed.
