Description

Technical Field

[0001] This application relates to the field of water softener equipment technology, and in particular to a resin regeneration system, control method, device, water softening system and water softener equipment. Background Technology

[0002] Water contains hardness ions such as calcium and magnesium. These hardness ions negatively impact daily use, including reduced washing performance, decreased thermal efficiency due to scaling on pipe walls, and skin irritation. Water softeners use ion exchange resins to replace these hardness ions, effectively removing them and softening the water. However, the replacement capacity of ion exchange resins is limited; once the resin becomes ineffective, it needs to be regenerated using high-concentration saline solution.

[0003] In existing water softening systems, the softening process of ion exchange resins involves softening and regeneration. The softening process removes hardness ions from the water before the resin becomes ineffective. The regeneration process involves using high-concentration brine to regenerate the resin after it has become ineffective. The principle is to leverage the ion concentration advantage, utilizing the sodium ions in the brine to exchange calcium ions on the resin. 2+ Mg 2 + Ions of equal hardness.

[0004] Existing soft water systems cannot fully utilize the exchange capacity of ion exchange resins, and the resin regeneration efficiency is low, which easily leads to a large loss of brine and waste of regenerated salt. Summary of the Invention

Detailed Implementation

[0051] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0053] It is understood that the terms "first," "second," etc., used herein may be used to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another. For example, without departing from the scope of this application, a first resistor may be referred to as a second resistor, and similarly, a second resistor may be referred to as a first resistor. Both the first resistor and the second resistor are resistors, but they are not the same resistor.

[0054] It is understood that the term "connection" in the following embodiments should be understood as "electrical connection," "communication connection," etc., if the connected circuits, modules, units, etc., have electrical signal or data transmission with each other.

[0055] It is understandable that "at least one" refers to one or more, and "multiple" refers to two or more. "At least a part of an element" refers to part or all of an element.

[0056] When used herein, the singular forms of “a,” “an,” and “the” may also include the plural forms unless the context clearly indicates otherwise. It should also be understood that the terms “comprising / including” or “having,” etc., specify the presence of the stated features, wholes, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof. Meanwhile, the term “and / or” as used in this specification includes any and all combinations of the associated listed items.

[0057] As described in the background section, the efficiency of existing water softening systems in removing hardness ions from water using ion exchange resins still has significant room for improvement. Ion exchange resins, as high-molecular polymers, have interaction sites with hardness ions distributed on the surface and internal pores of the resin particles. Increasing the temperature significantly enhances the ion exchange reaction of the resin. Furthermore, regenerating the ion exchange resin using a brine solution at a specific temperature can effectively improve regeneration efficiency.

[0058] Typically, existing resin regeneration systems use a layered salt tank 141 and a siphon device to produce regenerated brine. However, these methods do not control the temperature of the regenerated brine, and the siphon method makes it difficult to effectively control its concentration, thus hindering efficient regeneration of the ion exchange resin.

[0059] This embodiment provides a resin regeneration system that can not only control the temperature of the regenerated brine, but also more precisely control the concentration of the regenerated salt in the brine. This stabilizes and improves the regeneration capacity of the ion exchange resin while effectively saving the amount of regenerated salt used, thus avoiding waste and environmental pollution.

[0060] like Figure 1 As shown, the resin regeneration system provided in this embodiment is applied to a soft water system. The soft water system includes a resin regeneration system, a resin container, solenoid valves F1, F2, F3, F4, and F5. The inlet of the resin container is connected to the inlet of the soft water system via solenoid valve F1, and the outlet of the resin container is connected to the outlet of the soft water system via solenoid valve F2. The outlet of the resin container is also connected to the inlet of the soft water system via solenoid valve F3, and the inlet of the resin container is also connected to the wastewater outlet of the soft water system via solenoid valve F4. The resin regeneration system is connected to the inlet of the soft water system via solenoid valve F5. The resin regeneration system is used to draw water from the inlet of the soft water system. The inlet of the soft water system is used to receive raw water, the outlet of the soft water system is used to output softened water, and the wastewater outlet of the soft water system is used to discharge wastewater.

[0061] The water softening system includes a production mode, a backwash mode, and a regeneration mode. In production mode, solenoid valves F1 and F2 are activated, allowing raw water to be softened by passing it through the resin container and output as softened water through the outlet. In backwash mode, solenoid valves F3 and F4 are activated, allowing raw water to enter through the outlet and exit through the inlet of the resin container, performing a backwash to remove impurities from the ion exchange resin. In regeneration mode, solenoid valves F5 and F4 are activated, and in conjunction with the resin regeneration system, the ion exchange resin inside the resin container is regenerated.

[0062] It should be noted that the specific connection structure of the water softening system can also refer to other existing water softening system connection structures. This is only used as an example and is not a specific limitation.

[0063] In one embodiment, such as Figure 1As shown, a resin regeneration system is provided, including: a control module 110, a water inlet module 120, a heating module 130, and a water outlet module 140, wherein the control module 110 is connected to the water inlet module 120, the heating module 130, and the water outlet module 140, respectively, and the water inlet module 120 is connected to the water outlet module 140 through the heating module 130.

[0064] Specifically, in this embodiment, the control module 110 can be a microcontroller, a microprocessor unit, or a central processing unit, etc. This embodiment does not limit the specific type of the control module 110, and it can be adaptively configured according to the needs of the actual application scenario. The control module 110 can control the inlet module 120, the heating module 130, and the outlet module 140 to perform corresponding actions according to a preset control program to complete the regeneration of the ion exchange resin in the resin container.

[0065] In this embodiment, the water inlet module 120 can perform water intake treatment according to the control commands of the control module 110. In practical applications, the water inlet module 120 can also be used to store a portion of the water, thereby controlling the flow rate parameters and duration of the incoming water. In some embodiments, the water inlet module 120 can control the water inlet pipeline according to the control commands. Specifically, in this embodiment, the water inlet module 120 connects to the water body from the inlet of the soft water system to generate the target brine solution.

[0066] In one feasible embodiment, the resin regeneration system provided in this application further includes a filtration module 150, with an inlet water module 120 connected to the filtration module 150. The filtration module 150 is connected to the inlet water module 120 via a solenoid valve F5. The inlet water module 120 receives water filtered by the filtration module 150 from a soft water system, thereby further improving the precise control of the concentration of the generated brine by the resin regeneration system. It should be understood that... Figure 1 As shown, in this embodiment, the control module 110 can control the on / off state of the solenoid valve F5 to realize the water intake action of the water intake module 120. When the control module 110 controls the solenoid valve to be turned on, the water intake module 120 is connected to the water filtered by the filter module 150 through the solenoid valve F5.

[0067] In this embodiment, the heating module 130 can heat the water according to the control commands of the control module 110. In practical applications, the heating module 130 can heat the water to be added to the salt tank 141 or resin container to the target temperature. This embodiment improves the resin regeneration efficiency by controlling the water temperature.

[0068] In this embodiment, the water outlet module 140 is used to generate the target brine solution and determine the actual water path leading to the resin container. In practical applications, the water outlet module 140 is connected to the resin container of the soft water system. The water outlet module 140 includes at least two water flow directions leading to the resin container, wherein one water flow direction includes the brine tank 141, and the other water flow direction does not include the brine tank 141.

[0069] In one feasible embodiment, the provided resin regeneration system further includes a drive module 160, and the effluent module 140 is connected to the resin container via the drive module 160. Wherein, as Figure 1 As shown, the drive module 160 is used to provide water output driving force for the water output module 140. The control module 110 can control the water output flow rate of the water output module 140 by controlling the drive power of the drive module 160, and guide the water output by the water output module 140 to the sewage outlet through the resin container.

[0070] Specifically, the control module 110 controls the heating module 130 to heat the water output from the water inlet module 120 according to the target heating power, and controls the water outlet module 140 to output the target regenerated liquid to the resin container according to the target water flow direction.

[0071] In a specific embodiment, the target heating power corresponds to the target temperature of the water heated by the heating module 130. In this embodiment, the control module 110 can determine the target temperature based on the real-time state of the ion exchange resin in the resin container, and determine the target heating power based on the correspondence between the target temperature and the target heating power. It should be noted that this embodiment does not limit the specific value of the target heating power; the corresponding power value can be matched according to the needs of the actual application scenario. The specific value of the target heating power can also be determined with reference to the product type of the heating module 130; this embodiment does not limit the specific product type of the heating module 130.

[0072] The target water flow direction includes the two water flow directions in the aforementioned embodiments. In actual application, during the regeneration process of ion exchange resin in the resin container, the control module 110 in this embodiment controls the water heated by the heating module 130 to pass through the salt tank 141 at a preset flow rate to generate a target regeneration liquid with a preset salt concentration. Then, the target regeneration liquid with a target temperature is controlled to flow through the resin container to fully contact the ion exchange resin, carrying out hardness ions that remain in the ion exchange resin pipeline or are avoided, thereby achieving full regeneration of the ion exchange resin.

[0073] In summary, this embodiment provides a resin regeneration system. By adding a heating module 130 to the resin regeneration system, the target regeneration liquid is heated to a certain temperature before being output to the resin container, and then the target regeneration liquid is delivered to the resin container. This allows the salt solution input into the resin container for resin regeneration to always be at a temperature that enables efficient resin regeneration, greatly improving the efficiency of resin regeneration and reducing the requirements for concentration control of the regeneration salt solution to a certain extent, effectively improving the stability of the resin regeneration system during resin regeneration.

[0074] In one embodiment, the resin regeneration system operates in three modes: a preheating mode, a hot-soluble salt regeneration mode, and a hot-slow rinse mode. The resin regeneration system functions after the soft water system enters regeneration mode to control the regeneration of the ion exchange resin. The preheating mode primarily involves preheating the water in the soft water system and the ion exchange resin in the resin container. The hot-soluble salt regeneration mode utilizes the heated water to generate a target regeneration liquid, and regenerates the ion exchange resin in the resin container based on this target regeneration liquid. The hot-slow rinse mode uses water at a specific temperature to reuse residual salt solution in the pipelines and effectively reduce the regeneration salt content in the resin container.

[0075] Specifically, when the soft water system enters the regeneration mode, the control module 110 initiates the preheating mode and runs for a first preset time. After initiating the preheating mode, the control module 110 heats the water output from the inlet module 120 according to the preset inlet flow rate via the heating module 130, and outputs water at a certain temperature through the outlet module 140 (excluding the brine tank 141) into the resin container, and discharges wastewater through the wastewater outlet of the soft water system. In actual implementation, in the preset mode, only the water output from the inlet module 120 is heated; no regeneration brine is generated.

[0076] After running for a first preset time in preheating mode, control module 110 starts the hot-soluble salt regeneration mode and runs for a second preset time. After starting the hot-soluble salt regeneration mode, control module 110 heats the water output from inlet module 120 according to a preset inlet flow rate via heating module 130, and outputs a target regenerated liquid with a certain temperature into the resin container via outlet module 140 (including salt tank 141) in the direction of water flow, and discharges wastewater through the wastewater outlet of the soft water system. In specific implementation, the hot-soluble salt regeneration mode not only requires heating the water output from inlet module 120, but also requires generating regenerated salt solution according to preset inlet flow rate parameters and preset outlet flow rate parameters.

[0077] After running for a second preset time in the hot-dissolving salt mode, the control module 110 starts the hot-slow wash mode and runs for a third preset time. After starting the hot-slow wash mode, the control module 110 heats the water output from the inlet module 120 according to a preset inlet flow rate via the heating module 130, and outputs water at a certain temperature through the outlet module 140 (excluding the salt tank 141) into the resin container, and discharges wastewater through the wastewater outlet of the soft water system. It should be noted that the control module 110 controls the water flow direction in the same direction in both the hot-slow wash mode and the preheating mode, but the hot-slow wash mode runs after the hot-dissolving salt mode to fully utilize the regenerated salt remaining in the water path and to thoroughly remove hardness ions exchanged in the resin container.

[0078] It should be noted that this embodiment does not determine the specific values ​​of the first preset time, the second preset time, and the third preset time. The first preset time, the second preset time, and the third preset time can all be determined based on the parameters of each module and the water parameters under the system's operating conditions.

[0079] For example, when determining the first preset time, it is necessary to ensure that within the first preset time, the control module 110 can raise the water and water flow pipes in the resin regeneration system to a certain temperature through the heating module 130, and raise the temperature of the ion exchange resin in the resin container to a certain temperature, so as to improve the utilization efficiency of regenerated salt in the subsequent regeneration mode.

[0080] When determining the second preset time, the total time required for the second preset time needs to be determined based on parameters such as the activity capacity of the ion exchange resin, the amount of regenerated salt, the influent flow rate, the effluent flow rate, the length of the salt dissolving pipe in the salt tank 141, and the concentration and density of the regenerated salt solution.

[0081] When determining the third preset time, it is necessary to monitor the total dissolved solids (TDS) value of the effluent from the wastewater outlet of the soft water system and the TDS value of the influent from the inlet in real time, ensuring that the difference between the effluent TDS value and the influent TDS value is within the preset TDS value threshold range. Specifically, when the difference between the effluent TDS value and the influent TDS value is within the preset TDS value threshold range, after stopping the hot slow wash mode, the water softened through the resin container will not have an odor and will not affect the normal use of the soft water system. It should be noted that the TDS value threshold can be 200 mg / L; this embodiment does not specifically limit the TDS value threshold.

[0082] This embodiment can effectively improve the utilization efficiency of the regenerated salt in the resin regeneration system and enhance the regeneration capacity of the ion exchange resin by executing the preheating module, the hot soluble salt regeneration mode, and the hot slow washing mode in a preset order.

[0083] In one embodiment, if the system operating mode is a preheating mode or a hot slow wash mode, the control module 110 controls the water outlet module 140 to output the target liquid to the resin container in the first water flow direction, wherein the first water flow direction does not pass through the salt tank 141.

[0084] If the system is in hot-dissolved salt regeneration mode, the control module 110 controls the water outlet module 140 to output the target regeneration liquid to the resin container in the second water flow direction, wherein the second water flow direction passes through the salt tank 141.

[0085] Specifically, in this embodiment, the target liquid is water with a certain temperature that does not pass through the brine tank water path. The target regeneration liquid is brine with a certain temperature and a certain salt concentration that passes through the brine tank water path. It should be noted that in the hot slow wash mode, since some regeneration salt may remain in the water path, the target liquid can also be water containing salt.

[0086] In practical applications, the specific structure of the resin regeneration system provided in this embodiment can be as follows: Figure 2 As shown, the water inlet module 120 includes a water tank 121 and a first water pump 122. The water tank 121 includes a first outlet and a second outlet. The heating module 130 includes a heating element assembly 131. The water outlet module 140 includes a salt tank 141 and a first three-way valve 142. The first outlet of the water tank 121 is connected to the inlet of the salt tank 141 through the heating element assembly 131. The outlet of the salt tank 141 is connected to the first inlet of the first three-way valve 142. The second inlet of the first three-way valve 142 is connected to the second outlet of the water tank 121. The outlet of the first three-way valve 142 is connected to a resin container.

[0087] At this time, the first water flow direction is the second outlet of water tank 121 - the second inlet of the first three-way valve 142 - the outlet of the first three-way valve 142 - the resin container, and the second water flow direction is the first outlet of water tank 121 - the heating element assembly 131 - the inlet of salt tank 141 - the outlet of salt tank 141 - the first inlet of the first three-way valve 142 - the outlet of the first three-way valve 142 - the resin container.

[0088] The specific structure of the resin regeneration system provided in this embodiment can also be as follows: Figure 3As shown, the water inlet module 120 includes a water tank 121 and a first water pump 122, the heating module 130 includes a heating element assembly 131, and the water outlet module 140 includes a salt tank 141, a first three-way valve 142, and a second three-way valve 143. The outlet of the water tank 121 is connected to the inlet of the second three-way valve 143 through the heating element assembly 131. The first outlet of the second three-way valve 143 is connected to the inlet of the salt tank 141, the outlet of the salt tank 141 is connected to the first inlet of the first three-way valve 142, the second inlet of the first three-way valve 142 is connected to the second outlet of the second three-way valve 143, and the outlet of the first three-way valve 142 is connected to a resin container.

[0089] At this time, the first water flow direction is: outlet of water tank 121 - heating element assembly 131 - inlet of second three-way valve 143 - second outlet of second three-way valve 143 - second inlet of first three-way valve 142 - outlet of first three-way valve 142 - resin container; the second water flow direction is: outlet of water tank 121 - heating element assembly 131 - inlet of second three-way valve 143 - first outlet of second three-way valve 143 - inlet of salt tank 141 - outlet of salt tank 141 - first inlet of first three-way valve 142 - outlet of first three-way valve 142 - resin container.

[0090] In one embodiment, if the system operating mode is preheating mode, the control module 110 controls the water inlet module 120 to output water according to the first flow parameter. If the system operating mode is hot-dissolved salt regeneration mode, the control module 110 controls the water inlet module 120 to output water according to the second flow parameter, wherein the first flow parameter is greater than or equal to the second flow parameter.

[0091] In a specific embodiment, such as Figure 2 or Figure 3 As shown, the water inlet module 120 in this embodiment includes a first water pump 122. The control module 110 can control the water inlet flow rate of the resin regeneration system by controlling the PWM parameters of the first water pump 122. In practical applications, controlling the water inlet flow rate in the hot-soluble salt regeneration mode to a lower second preset flow rate parameter can ensure that the ion exchange resin in the resin container has more sufficient contact with the target regeneration liquid, thereby improving the regeneration efficiency of the ion exchange resin and the utilization rate of the regeneration salt.

[0092] In one embodiment, such as Figure 4 As shown, the resin regeneration system also includes a temperature detection module 170, wherein the control module 110 is connected to the temperature detection module 170, and the temperature detection module 170 is set in the water outlet pipe of the water inlet module 120 to detect the real-time water inlet temperature of the water output by the water inlet module 120.

[0093] In practical applications, the temperature detection module 170 can be a device for measuring water temperature, such as a temperature sensor or temperature component. This embodiment does not limit the type of device for the temperature detection module 170, and it can be configured according to the needs of the actual application scenario.

[0094] The control module 110 determines the target heating power based on the real-time inlet water temperature, system operating mode, and preset temperature parameters.

[0095] Specifically, the preset temperature parameters in this embodiment include a standard temperature and an optimal temperature. The optimal temperature is the optimal value of the water temperature parameter required during the regeneration of the resin container. In practical applications, the optimal value of the water temperature parameter can be obtained through research and analysis of the resin material. For each soft water system, the optimal value of the water temperature parameter is fixed. The standard temperature is a temperature value lower than the optimal temperature.

[0096] The preset temperature parameters differ slightly depending on the system's operating mode. Furthermore, since the water temperature entering the heating module 130 varies with the seasons, the water temperature received by the inlet module 120 is uncertain.

[0097] In this embodiment, the control module 110 can effectively determine the target heating power of the heating module 130 by acquiring the real-time inlet water temperature and preset temperature parameters, and in conjunction with the actual application scenario of the system operation mode, thereby ensuring that the water temperature is always at the optimal value of the corresponding system operation mode.

[0098] In one embodiment, if the system operating mode is hot-dissolving salt regeneration mode, the control module 110 determines the target heating power based on the real-time inlet water temperature, the standard temperature of dissolved salt, and the optimal brine temperature.

[0099] Specifically, the standard salt dissolution temperature and the optimal brine temperature are both preset temperature parameters required for the corresponding hot salt dissolution regeneration mode.

[0100] In this embodiment, by controlling the heating module 130 to heat according to the target heating power, the temperature of the target regenerated brine can be stabilized within the range of the standard salt dissolution temperature and the optimal brine temperature.

[0101] In a specific embodiment, if the real-time inlet water temperature equals the standard salt dissolution temperature, the control module controls the heating module 130 to heat according to the first heating power. Specifically, the first heating power can be the default heating power of the heating module 130. Heating according to the default heating power ensures that the water temperature output by the heating module 130 is the optimal brine temperature. This embodiment does not limit the specific value of the first heating power. When the real-time inlet water temperature equals the standard salt dissolution temperature, there is no need to adjust the default heating power of the heating module 130; simply controlling the heating module 130 to start operating in the default mode is sufficient.

[0102] When the real-time inlet water temperature is higher than the standard salt dissolution temperature, the control module 110 controls the heating module 130 to heat at a second heating power, which is lower than the first heating power. Specifically, a real-time inlet water temperature higher than the standard salt dissolution temperature means that heating the water at the current heating power would result in a water temperature output by the heating module 130 that is higher than the optimal brine temperature. Therefore, a lower second heating power is needed to control the heating module 130 to heat the water.

[0103] When the real-time inlet water temperature is lower than the standard salt dissolution temperature, the control module 110 controls the heating module 130 to heat at a third heating power, where the third heating power is greater than the first heating power. Specifically, a real-time inlet water temperature lower than the standard salt dissolution temperature means that heating the water at the current heating power would cause the water temperature output by the heating module 130 to be lower than the optimal brine temperature. Therefore, a larger third heating power is required to control the heating module 130 to heat the water.

[0104] When the real-time inlet water temperature is greater than or equal to the optimal brine temperature, the control module 110 controls the heating module 130 to stop heating, wherein the optimal brine temperature is greater than the standard salt dissolution temperature.

[0105] In practical implementation, if the real-time inlet water temperature is already equal to the optimal inlet water temperature, there is no need for the heating module 130 to continue heating the water. This can ensure the stability of the temperature parameters of the resin regeneration module while avoiding excessively high noise water temperature, which could lead to abnormal heating of the ion exchange resin.

[0106] In one embodiment, if the system operating mode is hot slow wash mode, the control module 110 determines the target heating power based on the real-time inlet water temperature, the standard slow wash temperature, and the optimal slow wash temperature.

[0107] Specifically, the standard slow wash temperature and the optimal slow wash temperature are both preset temperature parameters required for the corresponding hot slow wash mode.

[0108] In this embodiment, by controlling the heating module 130 to heat according to the target heating power, the water temperature can be stabilized within the range of the standard slow wash temperature and the optimal slow wash temperature.

[0109] In a specific embodiment, if the real-time inlet water temperature is equal to the slow wash standard temperature, the control module 110 controls the heating module 130 to heat according to the fourth heating power.

[0110] When the real-time inlet water temperature is greater than the standard slow wash temperature, the control module 110 controls the heating module 130 to heat according to the fifth heating power, wherein the fifth heating power is less than the fourth heating power.

[0111] When the real-time inlet water temperature is lower than the standard temperature for slow washing, the control module 110 controls the heating module 130 to heat according to the sixth heating power, wherein the sixth heating power is greater than the fourth heating power.

[0112] When the real-time inlet water temperature is greater than or equal to the optimal slow wash temperature, the control module 110 controls the heating module 130 to stop heating, wherein the optimal slow wash temperature is greater than the standard slow wash temperature.

[0113] It should be noted that the power change logic of the control module 110 controlling the heating module 130 in the hot slow wash mode is similar to the control logic of the control module 110 in the hot dissolving salt mode, and will not be described in detail here.

[0114] It should be noted that the heating power of the first heating power, the second heating power, and the third heating power in this embodiment may be equal to or different from the heating power of the fourth heating power, the fifth heating power, and the sixth heating power under the corresponding operating conditions. This embodiment does not make specific limitations on this and can determine it according to the actual application scenario.

[0115] In a preferred embodiment, the connection structure of the resin regeneration system in this embodiment is as follows: Figure 5 As shown, the water inlet module 120 includes a water tank 121 and a first water pump 122, and the water outlet module 140 includes a first three-way valve 142, a brine tank 141, and a second three-way valve 143. The water inlet of the water tank 121 is used to connect water from the soft water system. The water outlet of the water tank 121 is connected to the water inlet of the first three-way valve 142 in sequence through the first water pump 122 and the heating module 130. The first outlet of the first three-way valve 142 is connected to the first inlet of the second three-way valve 143 through the brine tank 141. The second outlet of the first three-way valve 142 is connected to the second inlet of the second three-way valve 143. The outlet of the second three-way valve 143 is connected to the resin container of the soft water system.

[0116] Furthermore, the filtration module 150 includes a pre-filter 151, the heating module includes a heating element assembly 131, the drive module 160 includes a second water pump 161 and a check valve 162, and the temperature detection module 170 includes a temperature sensing bulb assembly 171. The outlet of the pre-filter 151 is connected to the inlet of the water tank 121 via a solenoid valve F5. The outlet of the second three-way valve 143 is connected to the resin container of the soft water system via the second water pump 161 and the check valve 162.

[0117] It should be noted that, by setting the second three-way valve 143 in this embodiment, it is possible to control the water temperature regardless of whether the water is output to the resin container through the first water flow direction or the second water flow direction, thereby ensuring the stability of the water temperature during the resin regeneration process.

[0118] In one embodiment, the salt tank 141 includes at least one salt dissolving channel, in which the water flow direction is horizontal.

[0119] In a specific embodiment, the salt tank 141 can be a single-layer or multi-layer salt dissolving channel structure. However, regardless of whether it is a single-layer or multi-layer salt dissolving channel structure, the water flow direction in the salt tank 141 in this embodiment is generally horizontal. It should be noted that the salt tank 141 in this embodiment is horizontally positioned, which effectively extends the effective length of the salt dissolving channel, thereby facilitating sufficient contact between the regenerated salt and the water, and further improving the concentration control of the regenerated salt solution.

[0120] On the other hand, the resin regeneration system provided in this embodiment can control the inlet and outlet flow rates of the salt tank 141 by setting a first water pump 122 and a second water pump 161 at the inlet and outlet of the salt tank 141, respectively. This allows for precise control of the salt concentration of the target regeneration liquid, thereby further enhancing the resin regeneration capacity.

[0121] In summary, this embodiment provides a resin regeneration system. By controlling the heating power of the heating module to be adjusted in real time according to the specific operating conditions of the actual system, the stability of the water temperature in the resin regeneration system can be effectively ensured, providing stable and optimal temperature parameters for the regeneration environment of the resin container, thereby improving the resin regeneration capacity. In addition, the resin regeneration system provided in this embodiment can also effectively control the concentration of the regenerated brine, generating regenerated brine with a preset concentration, and can adjust the brine concentration through various control methods, greatly improving the utilization rate of the regenerated salt. Furthermore, the brine tank in this embodiment does not use a siphon structure, effectively avoiding the problem of unstable brine concentration caused by siphon devices, and improving the regeneration stability of the resin regeneration system.
