This device includes resin towers containing adsorption resin, a tail gas distributor, a condenser, a condenser, and a desorption liquid receiving tank; there are three resin towers, two of which are constantly performing desorption operations, and the other performing adsorption operations. The inlet and outlet of the resin towers are connected to the tail gas distributor. In practical applications, this device can stably achieve the reuse of the steam desorbent, reducing the amount of steam desorbent used, lowering wastewater treatment costs, and realizing the reuse of the steam desorbent. This invention can be used in the resin steam desorption regeneration process after adsorption treatment of wastewater containing organic pollutants. It can also be used in adsorption separation processes in the chemical industry.

[0004] While the above solutions have the advantages mentioned above, they also have disadvantages: some industrial wastewater contains a lot of impurities, and the current traditional treatment methods mostly use neutralization tanks and sedimentation, which lack pretreatment of impurities in the wastewater, resulting in a lot of cleaning work in the later stage. At the same time, treatment inside the neutralization tank is prone to problems such as high consumption of chemicals, large amount of sludge, and inability to reuse. Utility Model Content

[0042] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0043] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0044] Example 1, as Figure 1-4As shown, the wastewater treatment device for resin regeneration includes a treatment tank 1, with multiple support legs 101 set at the bottom of the treatment tank to provide stable support; the treatment tank 1 has two inner cavities for treating different types of wastewater respectively, and a discharge pipe 105 at the bottom for discharging liquid; the treatment structure is set at the top of the treatment tank 1, including two water inlets 102, and an activated carbon plate 1025 inside for adsorbing organic matter.

[0045] The inlet 102 is equipped with a filter plate 1026 for solid-liquid separation. Two U-shaped frames 1021 are fixed to the top of the inlet 102, and a rotating shaft 1022 is installed inside the frame via bearings. A scraper 1023 is fixed to the surface of the rotating shaft 1022, and the scraper 1023 slides in contact with the surface of the filter plate 1026 to clean its surface. A gear 1024 is provided at one end of the rotating shaft 1022. A connecting frame 103 is symmetrically arranged on the top of the treatment tank 1, and a drive motor 1031 is installed inside the frame. The output end of the motor is connected to the transmission shaft. 1032, the drive shaft 1032 is equipped with a second gear 1033 that meshes with a first gear 1024 to achieve synchronous transmission; the lower part of the drive shaft 1032 is equipped with multiple stirring blades 1034 that extend into the treatment tank 1 to stir the wastewater and accelerate the fusion of the medicine solution. During operation, the wastewater enters the tank through the activated carbon plate 1025 and the filter plate 1026. The drive motor 1031 starts and drives the scraper 1023 to automatically clean the impurities on the surface of the filter plate 1026 through gear transmission. At the same time, the stirring blades 1034 promote the mixing and neutralization reaction of the wastewater.

[0046] In this embodiment, when the drive motor 1031 on the surface of the connecting frame 103 is working, the transmission shaft 1032 drives the gear 1033 and the stirring plate 1034 to rotate. The gear 1033 meshes with the gear 1024, causing the rotating shaft 1022 to rotate along the inside of the U-shaped frame 1021. This allows the scraper 1023 to slide along the surface of the filter plate 1026, scraping away larger particles of debris to prevent clogging, reduce work efficiency, and minimize the need for subsequent impurity cleaning. This, combined with the activated carbon plate 1025 at the bottom, provides dual filtration of the wastewater. At the same time, the stirring plate 1034 mixes the wastewater containing chemicals, improving neutralization efficiency and facilitating subsequent treatment of the wastewater with an electrodialysis desalination system.

[0047] Example 2, as Figure 1-4 As shown, the dosing structure of the wastewater treatment device for resin regeneration is set on the surface of the treatment tank 1. Two dosing pipes 104 are symmetrically connected and set on the top of the treatment tank 1. The inner wall of the dosing pipe 104 is provided with a partition 1041. A round hole 1042 is opened on the surface of the partition 1041 for controlling the dosing of the agent.

[0048] Two limiting shafts 1043 are fixed to the bottom of the partition plate 1041 and connected to the rotating disk 1044 via bearings. The rotating disk 1044 has a second circular hole 1045 with the same size as the first circular hole 1042 on its surface, and it meshes with the rack 1048 through the outer peripheral teeth 1046. The rack 1048 is connected to the output end of the electric push rod 1047. During operation, the electric push rod 1047 drives the rack 1048 to move, which drives the rotating disk 1044 to rotate, adjusting the overlap area between the second circular hole 1045 and the first circular hole 1042, thereby controlling the flow rate of the agent. When the two holes are completely aligned, the agent flows in fully; when they partially overlap, throttling is achieved; when they are completely misaligned, the channel is closed, solving the problems of non-adjustable flow rate, easy clogging, and agent waste in traditional dosing devices.

[0049] In this embodiment, different types of wastewater are collected into the acid waste liquid compartment and alkali waste liquid compartment inside the treatment tank 1 through two water inlets 102. By adding a chemical agent into the dosing pipe 104, the electric push rod 1047 is activated, which causes the rack 1048 to drive the teeth 1046, driving the rotating disk 1044 to rotate along the limiting shaft 1043 as a fixed point. This allows the second round hole 1045 to open and close with the first round hole 1042 on the surface of the partition 1041. By controlling the size of the area where the two intersect, the amount of chemical agent added is controlled, reducing waste.

[0050] Working principle: During use, different types of wastewater are collected in the acid and alkali waste compartments inside the treatment tank 1 through two inlets 102. Chemicals are added into the dosing pipe 104, activating the electric push rod 1047. This causes the rack 1048 to drive the teeth 1046, rotating the rotating disk 1044 along the limit shaft 1043. This allows the second circular hole 1045 to open and close with the first circular hole 1042 on the surface of the partition 1041. The amount of chemical added is controlled by the size of the intersecting area, reducing waste. Simultaneously, the drive motor 1031 on the surface of the connecting frame 103 operates via the transmission shaft 103. 2. The gear 1033 and the stirring plate 1034 are driven to rotate. The gear 1033 meshes with the gear 1024, causing the rotating shaft 1022 to rotate along the inside of the U-shaped frame 1021. The scraper 1023 slides along the surface of the filter plate 1026 to scrape off larger particles of waste, preventing blockage and reducing the need for subsequent cleaning. The activated carbon plate 1025 at the bottom performs double filtration of the wastewater. At the same time, the stirring plate 1034 mixes the wastewater containing chemicals to improve neutralization efficiency. The wastewater is then discharged through the discharge pipe 105, which facilitates subsequent treatment of the wastewater with the electrodialysis desalination system.

[0051] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
