[0030] Example 1

[0031] like Figure 1 and Figure 2As shown, a device for efficiently removing iodide ions from brine includes an adsorption tank 1, with supports 2 at both ends of the tank's bottom. The supports 2 facilitate the support of the entire device and its use. The adsorption tank 1 is used to guide the brine flow, thus facilitating brine treatment. The adsorption tank 1 contains a supported activated carbon adsorbent. A supported activated carbon adsorbent refers to an active component (such as silver, copper, or their compounds) with the ability to adsorb iodide ions, loaded onto the surface of activated carbon using physical or chemical methods. Activated carbon has a large specific surface area and abundant pore structure, providing numerous adsorption sites. The loaded active component has a strong affinity for iodide ions. For example, activated carbon loaded with silver ions allows the silver ions to react chemically with iodide ions to form insoluble silver iodide, thus achieving efficient adsorption of iodide ions. This adsorbent not only has a large adsorption capacity but also a fast adsorption rate and high selectivity for iodide ions in the brine, and can avoid interference from other ions to a certain extent. The top of the adsorption tank 1 is equipped with an inlet pipe 14 and a drain pipe 13 near both ends. The inlet pipe 14 is for easy connection to the brine delivery pipeline, facilitating the injection of brine into the adsorption tank 1.

The iodide ion concentration detector 3, in conjunction with the detection probe 4, can quickly and effectively detect the iodide ion concentration in the brine inside the drain pipe 13. When the iodide ion concentration fails to meet the standard, an electrical signal is fed back to the electrically controlled valve 132, which then closes the drain pipe 13, preventing further discharge of brine. The bottom of the adsorption tank 1 is provided with a discharge pipe 17, which is connected to a screw conveyor assembly 5. The cooperation between the discharge pipe 17 and the screw conveyor assembly 5 is to facilitate the discharge of the loaded activated carbon adsorbent inside the adsorption tank 1 when it needs to be replaced.

[0033] like Figure 3 As shown, the top of the bracket 2 is provided with a plug 21, which is inserted into the inside of the connecting frame 12. The plug 21 is designed to allow the set screw 121 to rest against it. This structure ensures the stable installation and use of the bracket 2. Furthermore, the bottom of the bracket 2 is provided with multiple bolt holes 22, which facilitate the fixing of the bracket 2 with bolts.

[0034] like Figure 4 As shown, the iodine ion concentration detector 3 has symmetrically arranged fixing edges 31 on both sides, with multiple fixing holes 32 on each fixing edge 31. The fixing edges 31 and fixing holes 32 are designed to facilitate the fixing of the iodine ion concentration detector 3 with bolts. The side of the iodine ion concentration detector 3 has multiple connecting slots 33, which facilitate connection between the iodine ion concentration detector 3 and the detection probe 4 and the solenoid valve 132. Furthermore, the side of the iodine ion concentration detector 3 has a power connection wire 34, with a power connector 35 at the end of the power connection wire 34. The connection wire 34 and the power connector 35 facilitate power supply to the iodine ion concentration detector 3, facilitating its operation and use.

[0035] like Figure 5As shown, the end of the detection probe 4 facing the drain pipe 13 is provided with an adapter post 41, which is threadedly connected to the threaded hole 131. The adapter post 41 facilitates the threaded connection between the detection probe 4 and the threaded hole 131. The end of the adapter post 41 inserted into the drain pipe 13 is provided with a sensing probe 42. The sensing probe 42 facilitates the sensing of the iodine ion concentration in the brine. A connecting wire 43 is provided on the side of the detection probe 4, and a connecting plug 44 is provided at the end of the connecting wire 43. The connecting wire 43 and the connecting plug 44 facilitate the connection between the detection probe 4 and the iodine ion concentration sensor.

[0036] like Figure 6 As shown, the screw conveyor assembly 5 includes a conveying cylinder 51, a conveying screw 53, and a motor 52. The conveying screw 53 is disposed inside the conveying cylinder 51, with one end rotatably connected to the conveying cylinder 51. The motor 52 is fixed to the unopened end of the conveying cylinder 51, and its output end is connected to the conveying screw 53. This structure facilitates the rotation of the conveying screw 53 by the motor 52, thereby discharging the loaded activated carbon adsorbent inside the adsorption tank 1. A bearing 511 is provided at the unopened end of the conveying cylinder 51, allowing for easy rotatable connection with the conveying screw 53. A connecting pipe 512 is provided at the top of the conveying cylinder 51, with a connecting disc 513 at the top of the connecting pipe 512. A connecting shaft 531 is provided at one end of the conveying screw 53, and the connecting shaft 531 is interference-fitted with the bearing 511. This structure facilitates the rotation and use of the conveying screw 53.

[0045] Working Principle: During use, an appropriate amount of supported activated carbon adsorbent is injected into the adsorption tank 1. The feed port 15 is then sealed with the cap 6. The brine delivery pipe is connected to the inlet pipe 14, and the brine discharge pipe is connected to the drain pipe 13. After the brine enters the adsorption tank 1, the supported activated carbon adsorbent adsorbs iodide ions in the brine. The adsorbed brine is then discharged through the drain pipe 13, thus removing the iodide ions. The iodide ion concentration detector 3, in conjunction with the detection probe 4, monitors the iodide ion concentration in real time. When the iodide ion concentration in the discharged brine is found to be substandard, the iodide ion concentration detector 3 sends a signal to the solenoid valve 132, causing the valve to close and preventing further discharge of brine. When the adsorption effect of the supported activated carbon adsorbent deteriorates, it can be eluted using an eluent. When the supported activated carbon adsorbent becomes ineffective, the screw conveyor assembly 5 can be activated to discharge the ineffective adsorbent.

[0046] In summary, compared with the prior art, this application adds a sufficient amount of supported activated carbon adsorbent to the adsorption tank 1, and then injects brine containing iodide ions into the adsorption tank 1 through the inlet pipe 14. After the brine passes through the supported activated carbon adsorbent, the iodide ions inside will be adsorbed, and the brine with adsorbed iodide ions will be discharged from the drain pipe 13. This can quickly and effectively remove iodide ions from the brine, which can be completed during the brine transportation process. It is efficient and convenient. In addition, the drain pipe 13 is equipped with an iodide ion concentration detector 3 and a detection probe 4, which facilitates the measurement of the iodide ion concentration in the discharged brine and avoids poor iodide ion adsorption effect in the brine, resulting in an excessively high iodide ion concentration.
