Description

Technical Field

[0001] This utility model relates to the field of ion exchange resin regeneration technology, specifically to a water treatment ion exchange resin regeneration device. Background Technology

[0002] In today's rapidly developing industrial landscape, the discharge of heavy metal industrial wastewater has become increasingly prominent, posing a serious threat to the ecological environment and human health. Ion exchange technology, as a mature and effective method for treating heavy metal wastewater, has been widely applied in industrial wastewater treatment. Its basic principle is to utilize the functional groups on the ion exchange resin to react with heavy metal ions in the wastewater, removing the heavy metal ions and thus purifying the wastewater. However, during operation, ion exchange resins gradually reach saturation and lose their ability to remove heavy metal ions. To restore the resin's exchange performance, regeneration is necessary. Currently, a common regeneration method is to rinse the saturated resin with a regeneration solution (such as sodium chloride solution). During regeneration, ions in the regeneration solution react with the heavy metal ions adsorbed on the resin, displacing the heavy metal ions from the resin and restoring its exchange capacity.

[0003] Existing ion exchange resin regeneration equipment typically uses the same concentration of fresh regeneration solution throughout the entire regeneration process, which has significant drawbacks. Firstly, the volume of fresh regeneration solution required for the entire regeneration process is usually 3 to 5 times the resin volume. This means that existing ion exchange resin regeneration equipment consumes a large amount of regeneration solution throughout the entire regeneration process, significantly increasing water treatment costs. Secondly, existing ion exchange resin regeneration equipment cannot dynamically adjust the concentration of the regeneration solution according to the actual adsorption status of the resin and the needs of each regeneration stage. In actual operation, the resin's demand for regeneration solution concentration gradually decreases. Therefore, using the same concentration of regeneration solution throughout the regeneration process leads to generally high consumption of regeneration acids and alkalis, resulting in resource waste. It also leads to a low pH compliance rate in the regeneration wastewater, often requiring additional acid or alkali addition for neutralization, further increasing water treatment costs.

[0004] Given the aforementioned problems with existing ion exchange resin regeneration equipment, developing a water treatment ion exchange resin regeneration device capable of recycling the regeneration solution and dynamically adjusting its concentration is of significant practical importance. Utility Model Content

[0007] (II) Technical Solution

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a water treatment ion exchange resin regeneration device, including an ion exchange resin tank, and further comprising:

[0009] The water inlet module includes a drug inlet pipe that is connected to the ion exchange resin tank;

The chemical tank is used to store the regeneration solution, and the circulating pump is used to pump the regeneration solution in the chemical tank into the ion exchange resin tank through the inlet pipe.

[0012] The detection and control module is located on the detection water pipe and connected to the inlet of the circulation pump.

The output end of the control device is electrically connected to the first control valve, the second control valve, and the circulation pump.

[0015] The pH meter is used to detect the pH value of the waste liquid in the water pipe and send it to the control device. The hardness meter is used to detect the hardness value of the waste liquid in the water pipe and send it to the control device. The control device is used to receive the pH value signal sent by the pH meter and the hardness value signal sent by the hardness meter, and control the opening or closing of the first control valve, the second control valve and the circulation pump according to the detection results.

[0016] In a further configuration, the water outlet of the aforementioned medicine tank and the second water outlet branch pipe are connected to the water inlet of the circulating pump through a three-way valve. The water outlet of the medicine tank is equipped with a third control valve and a flow meter. The output end of the control device is also electrically connected to the third control valve and the flow meter. The control device is also used to control the opening or closing of the third control valve.

[0017] Further, the aforementioned water inlet module also includes a raw water pipe and a rotary water distributor. The rotary water distributor is located on the top wall inside the ion exchange resin tank. The raw water pipe and the chemical inlet pipe are connected to the rotary water distributor through a three-way valve. The rotary water distributor is used to input the raw water in the raw water pipe or the regenerated chemical solution in the chemical inlet pipe into the ion exchange resin tank.

[0018] Further, the aforementioned rotating water distributor includes a mounting base, a rotating shaft, and at least two water distribution pipes. The mounting base is fixed to the top wall inside the ion exchange resin tank and is rotatably connected to the rotating shaft. The water distribution pipes are arranged in a ring-shaped interval around the rotating shaft. The rotating shaft has a hollow structure and is connected to each water distribution pipe. The water distribution pipe includes two symmetrically arranged water outlet areas and back water areas.

The water collection plates are used to guide the liquid in the ion exchange resin tank to the backwash filter head. The outlet pipe and the test water pipe are connected to the backwash filter head through a three-way valve. The backwash filter head is used to filter the liquid flowing out of the ion exchange resin tank and transport the filtered liquid to the outlet pipe or the test water pipe.

[0022] (III) Beneficial Effects

[0023] Compared with the prior art, the water treatment ion exchange resin regeneration equipment provided by this utility model has the following beneficial effects:

[0024] 1. When using the water treatment ion exchange resin regeneration equipment provided by this utility model, firstly, the circulation pump is started to pump the regeneration solution in the reagent tank into the ion exchange resin tank through the inlet pipe to rinse the resin. Subsequently, the waste liquid formed after rinsing is input into the detection water pipe. The detection control module detects the waste liquid in the detection water pipe to determine whether the waste liquid can be recycled as regeneration solution and whether the resin has recovered its exchange capacity. If the detection result shows that the waste liquid can be recycled as regeneration solution, the detection control module will control the detection water pipe to connect with the circulation pump. The circulation pump will pump the waste liquid and the new regeneration solution output from the reagent tank into the ion exchange resin tank through the inlet pipe to realize the recycling of the regeneration solution. Otherwise, the detection control module will control the detection water pipe to be cut off from the circulation pump, and discharge the waste liquid in the detection water pipe to the outside of the equipment to avoid interference from ineffective waste liquid to the system. This cycle is repeated until the detection result shows that the resin has fully recovered its exchange capacity. At this time, the circulation pump is turned off to stop the supply of regeneration solution to the ion exchange resin tank. As can be seen, this invention achieves the recycling of the regenerated pharmaceutical solution. This recycling mechanism not only ensures the continuous flow of the regenerated pharmaceutical solution within the system, but also cleverly incorporates the usable waste liquid generated during the regeneration process back into the recycling system, working synergistically with the newly added regenerated pharmaceutical solution. In this way, the amount of new regenerated pharmaceutical solution added is significantly reduced, effectively lowering the overall cost of using the regenerated pharmaceutical solution, while also reducing waste liquid discharge and maximizing resource utilization.

[0025] 2. As the regeneration process progresses, more and more resin is regenerated, and the resin's ability to absorb the regeneration solution gradually decreases, leading to an increasing surplus of ions in the waste liquid. During the regeneration process, this invention uses a detection and control module to monitor the waste liquid in real time. If the waste liquid contains surplus ions, the detection result indicates that the batch of waste liquid can be recycled as a regeneration solution. At this point, the detection and control module will control the mixing of the waste liquid with the new regeneration solution, reducing the concentration of the regeneration solution. This satisfies the regeneration requirements while avoiding resource waste, achieving dynamic adjustment of the regeneration solution concentration based on the actual adsorption of the resin and the needs of the regeneration stage. This dynamic adjustment of the regeneration solution concentration significantly reduces acid and alkali consumption during the regeneration process, improves the pH compliance rate of the regenerated waste liquid, and further reduces the cost of the entire water treatment process.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] This invention provides a water treatment ion exchange resin regeneration device to solve the problems of how to recycle the regeneration solution and dynamically adjust the concentration of the regeneration solution.

[0035] See Figure 1 As shown, Figure 1 The diagram shows the connection of the water treatment ion exchange resin regeneration equipment in this embodiment. The water treatment ion exchange resin regeneration equipment includes an ion exchange resin tank 1, an inlet module, an outlet module, a circulating dosing module 4, and a detection and control module 5.

[0036] The water inlet module includes a drug inlet pipe 21 that is connected to the ion exchange resin tank 1.

[0037] The effluent module includes a detection water pipe 31 connected to the ion exchange resin tank 1. The detection water pipe 31 is used to output the waste liquid generated during the regeneration process inside the ion exchange resin tank 1.

[0038] The circulating dosing module 4 includes a chemical tank 41 and a circulating pump 42. The inlet of the circulating pump 42 is connected to the chemical tank 41, and the outlet is connected to the inlet pipe 21. The chemical tank 41 is used to store the regeneration solution. The circulating pump 42 is used to pump the regeneration solution in the chemical tank 41 into the ion exchange resin tank 1 through the inlet pipe 21.

[0039] The detection control module 5 is installed on the detection water pipe 31 and connected to the inlet of the circulation pump 42. The detection control module 5 is used to detect the waste liquid in the detection water pipe 31 and control the connection or disconnection of the detection water pipe 31 and the circulation pump 42 according to the detection results.

[0040] When using the water treatment ion exchange resin regeneration equipment described above, firstly, the circulation pump 42 is started to pump the regeneration solution in the reagent tank 41 into the ion exchange resin tank 1 through the inlet pipe 21 to rinse the resin 11. Subsequently, the waste liquid formed after rinsing is input into the detection water pipe 31. The detection control module 5 detects the waste liquid in the detection water pipe 31 to determine whether the waste liquid can be recycled as regeneration solution and whether the resin 11 has regained its exchange capacity. If the detection result shows that the waste liquid can be recycled as regeneration solution, the detection control module 5 will control the detection water pipe 31 to connect with the circulation pump 42. The circulation pump 42 will then pump the waste liquid and the new regeneration solution output from the reagent tank 41 together into the ion exchange resin tank 1 through the inlet pipe 21, realizing the recycling of the regeneration solution. Conversely, if the regeneration solution fails to regenerate, the detection control module 5 will control the detection water pipe 31 to disconnect from the circulation pump 42, discharging the waste liquid in the detection water pipe 31 outside the equipment to prevent ineffective waste liquid from interfering with the system. This process is repeated until the test results show that resin 11 has fully recovered its exchange capacity. At this point, the circulation pump 42 is turned off, and the supply of regenerated reagent to the ion exchange resin tank 1 is stopped. It can be seen that this invention achieves the recycling of the regenerated reagent. This recycling mechanism not only ensures the continuous flow of the regenerated reagent within the system but also cleverly incorporates the usable waste liquid generated during the regeneration process back into the recycling system, working synergistically with the newly added regenerated reagent. In this way, the amount of new regenerated reagent added is significantly reduced, effectively lowering the overall cost of using the regenerated reagent, while also reducing waste liquid discharge and maximizing resource utilization.

[0041] Furthermore, as the regeneration process progresses, more and more resin 11 is regenerated, and the resin 11's ability to absorb the regeneration solution gradually decreases, leading to an increasing surplus of ions in the waste liquid. During the regeneration process, this invention uses a detection and control module 5 to monitor the waste liquid in real time. If the waste liquid contains surplus ions, the detection result indicates that the batch of waste liquid can be recycled as a regeneration solution. At this time, the detection and control module 5 will control the mixing of the waste liquid with the new regeneration solution to reduce the concentration of the regeneration solution. This satisfies the regeneration requirements while avoiding resource waste, achieving the effect of dynamically adjusting the concentration of the regeneration solution based on the actual adsorption of resin 11 and the needs of the regeneration stage. This method of dynamically adjusting the concentration of the regeneration solution significantly reduces acid and alkali consumption during the regeneration process, improves the pH value qualification rate of the regenerated waste liquid, and further reduces the cost of the entire water treatment process.

[0042] See Figure 1As shown, in one embodiment of the detection control module 5, the detection control module 5 includes a pH meter 51, a hardness meter 52, and a control device 53. The pH meter 51 and the hardness meter 52 are sequentially installed on the detection water pipe 31, and both are electrically connected to the input terminal of the control device 53. The outlet terminal of the detection water pipe 31 is connected to a first outlet branch pipe 32 and a second outlet branch pipe 33. A first control valve 34 is installed on the first outlet branch pipe 32, and a second control valve 35 is installed on the second outlet branch pipe 33, and both are connected to the inlet terminal of the circulation pump 42. The output terminal of the control device 53 is electrically connected to the first control valve 34, the second control valve 35, and the circulation pump 42. The pH meter 51 is used to detect the pH value of the waste liquid in the water pipe 31 and send it to the control device 53; the hardness meter 52 is used to detect the hardness value of the waste liquid in the water pipe 31 and send it to the control device 53; the control device 53 is used to receive the pH value signal sent by the pH meter 51 and the hardness value signal sent by the hardness meter 52, and control the opening or closing of the first control valve 34, the second control valve 35 and the circulation pump 42 according to the detection results. Thus, as the regeneration process proceeds, the excess ions in the waste liquid increase while the concentration of metal ions decreases, therefore, the pH value and hardness value of the waste liquid detected by the pH meter 51 and the hardness meter 52 will gradually decrease. When the pH value drops to the first set range, it indicates that the batch of waste liquid can be recycled as a regenerated solution. At this time, the control device 53 controls the second control valve 35 to open and the first control valve 34 to close, connecting the second outlet branch pipe 33 and the circulation pump 42. This allows the circulation pump 42 to pump the waste liquid and the new regenerated solution output from the reagent tank 41 into the ion exchange resin tank 1 through the inlet pipe 21. Conversely, if the pH value drops to the first set range, it indicates that the batch of waste liquid cannot be recycled as a regenerated solution. At this time, the control device 53 controls the first control valve 34 to open and the second control valve 35 to close, cutting off the second outlet branch pipe 33 and the circulation pump 42. The first outlet branch pipe 32 can then directly discharge the batch of waste liquid outside the equipment for heavy metal recovery and other treatments. When the pH value drops to the second set range and the hardness value drops to the third set range, it indicates that the resin 11 has fully recovered its exchange capacity. At this time, the control device 53 shuts down the circulation pump 42, stopping the delivery of regenerated solution to the ion exchange resin tank 1 to avoid overuse of the regenerated solution. In summary, the detection and control module 5 can accurately detect the pH and hardness values ​​of the waste liquid through the pH meter 51 and the hardness meter 52. The control device 53 can precisely control the discharge and circulation of the waste liquid based on the detection results, ensuring the stability and effectiveness of the regeneration process.

[0043] The pH meter 51, hardness meter 52, and control device 53 described above can all use existing pH meters 51, hardness meters 52, and controllers. The first control valve 34 and the second control valve 35 described above can both use existing solenoid valves.

[0044] See Figure 1 As shown, based on the above embodiment, the outlet of the medicine tank 41 and the second outlet branch pipe 33 are connected to the inlet of the circulating pump 42 via a three-way valve. A third control valve 43 and a flow meter 44 are installed at the outlet of the medicine tank 41. The output of the control device 53 is also electrically connected to the third control valve 43 and the flow meter 44. The control device 53 is also used to control the opening or closing of the third control valve 43. Thus, the flow meter 44 can measure the amount of newly regenerated medicine output from the medicine tank 41, and combined with the control device 53 and the third control valve 43, the amount of newly regenerated medicine added can be dynamically adjusted to precisely and dynamically adjust the concentration and flow rate of the mixture of waste liquid and newly regenerated medicine.

[0045] The aforementioned third control valve 43 and flow meter 44 can both be existing solenoid valves and flow meters 44.

[0046] See Figure 1 As shown, in one embodiment of the water inlet module, the water inlet module further includes a raw water pipe 22 and a rotary water distributor 23. The rotary water distributor 23 is installed on the top wall inside the ion exchange resin tank 1. The raw water pipe 22 and the chemical inlet pipe 21 are connected to the rotary water distributor 23 via a three-way valve, thereby connecting to the ion exchange resin tank 1. The rotary water distributor 23 is used to input the raw water in the raw water pipe 22 or the regeneration solution in the chemical inlet pipe 21 into the ion exchange resin tank 1. In this way, the rotary water distributor 23 can evenly spray the raw water or regeneration solution onto the resin 11, avoiding situations where there is too much or too little liquid in certain areas, effectively improving the contact efficiency between the resin 11 and the liquid, thereby enhancing the regeneration effect and water treatment effect.

[0047] See Figure 1 As shown, solenoid valves electrically connected to the control device 53 can be installed on both the raw water pipe 22 and the chemical inlet pipe 21. Thus, during wastewater treatment, the control device 53 connects the raw water pipe 22 and the ion exchange resin tank 1, while simultaneously shutting off the chemical inlet pipe 21 and the ion exchange resin tank 1, allowing the raw water to be input into the ion exchange resin tank 1 for purification. During ion exchange resin 11 regeneration, the control device 53 connects the chemical inlet pipe 21 and the ion exchange resin tank 1, while simultaneously shutting off the raw water pipe 22 and the ion exchange resin tank 1, allowing the regeneration solution to be input into the ion exchange resin tank 1 for regeneration, thereby achieving flexible switching between the two working modes of water purification and regeneration.

[0048] See Figure 1As shown, in one embodiment of the rotary water distributor 23, the rotary water distributor 23 includes a mounting base 231, a rotating shaft 232, and at least two water distribution pipes 233. The mounting base 231 is fixed to the top wall inside the ion exchange resin tank 1 by means of screws or welding, and is rotatably connected to the rotating shaft 232. The water distribution pipes 233 are arranged in a ring-shaped interval around the rotating shaft 232. The rotating shaft 232 has a hollow structure and is connected to each water distribution pipe 233. The water distribution pipe 233 includes two symmetrically arranged water outlet areas 2331 and back water areas 2332. The water outlet areas 2331 have multiple water outlet holes 2333, which are evenly distributed along the axial direction of the water distribution pipe 233. In this way, the rotary water distributor 23 is designed to make the liquid sprayed uniformly from all directions, further improving the uniformity of water distribution, which is beneficial to the full regeneration of the resin 11 and the efficient water treatment.

[0049] Based on the above embodiment, the water outlet 2333 extends downwards and outwards from the inside of the water distribution pipe 233. This inclined design of the water outlet 2333 allows the liquid to generate a certain tangential force when sprayed, further promoting the rotation of the water distributor and increasing the liquid's diffusion range. This promotes the exchange reaction between the liquid and the resin 11, improves the uniformity and coverage of water distribution, and enhances the regeneration and water treatment effects.

[0050] Based on the above embodiments, the number of water distribution pipes 233 is between five and ten. This reasonable number of water distribution pipes 233 ensures uniform water distribution while avoiding overly complex structures, reducing equipment manufacturing costs and maintenance difficulty, and simultaneously ensuring that the liquid fully covers the resin 11, achieving good regeneration and water treatment effects.

[0051] See Figure 1 As shown, in one embodiment of the water outlet module, the water outlet module further includes a water collection plate 36, a backwash filter head 37, and an outlet pipe 38. There are at least two water collection plates 36, which are integrally connected to the bottom wall of the ion exchange resin tank 1. The backwash filter head 37 is installed on the bottom wall of the ion exchange resin tank 1. The water collection plate 36 guides the liquid in the ion exchange resin tank 1 to the backwash filter head 37. The outlet pipe 38 and the detection water pipe 31 are connected to the backwash filter head 37 via a three-way valve, thereby connecting to the ion exchange resin tank 1. The backwash filter head 37 filters the liquid flowing out of the ion exchange resin tank 1 and delivers the filtered liquid to the outlet pipe 38 or the detection water pipe 31. The outlet pipe 38 is used to output purified water. Thus, this water outlet module design not only guides the filtered liquid out of the ion exchange resin tank 1 but also backwashes the backwash filter head 37, effectively preventing clogging of the backwash filter head 37.

[0052] The backwash filter head 37 described above can be any existing backwash filter head 37.

[0053] See Figure 1 As shown, both the inlet and outlet of the aforementioned detection water pipe 31 and the outlet pipe 38 can be equipped with solenoid valves electrically connected to the control device 53. Thus, during wastewater treatment, the control device 53 connects the outlet pipe 38 and the ion exchange resin tank 1, while simultaneously shutting off the detection water pipe 31 and the ion exchange resin tank 1, allowing purified water to be output from the equipment via the outlet pipe 38 for use or discharge. During ion exchange resin 11 regeneration, the control device 53 connects the detection water pipe 31 and the ion exchange resin tank 1, while simultaneously shutting off the outlet pipe 38 and the ion exchange resin tank 1, allowing waste liquid to be input into the detection control module 5 for detection, thereby achieving flexible switching between the two working modes of water purification and regeneration.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
