Description

Technical Field

[0001] This invention relates to the fields of water treatment and industrial energy conservation, specifically to a circulating water treatment device and method based on the synergy of electrochemistry and permanent magnet magnetic field. Background Technology

[0002] In circulating water systems of large central air conditioning and industrial production, continuous evaporation leads to the concentration of minerals such as calcium and magnesium ions, easily causing scaling, microbial growth, and equipment corrosion. Currently, the industry mainly uses chemical, physical, and synergistic methods combining both to treat circulating water. Chemical methods are the mainstream approach, accounting for approximately 90% of treatments, involving the continuous addition of scale inhibitors, bactericides, and algaecides to suppress scaling and microbial growth. Physical methods often employ fixed-frequency magnetic water treatment technology, using magnetic fields to alter the ionic properties of the water to inhibit scaling. Some solutions combine electrolysis equipment to form a synergistic treatment mode, applying electrolysis and magnetization equipment to circulating water systems to combine the advantages of both technologies to improve treatment efficiency and meet the treatment needs of high-flow, high-hardness circulating water.

[0003] While synergistic treatment solutions combining electrochemistry and physical magnetization have emerged in the industry, these solutions generally suffer from simple mechanical stacking of equipment and a lack of core technologies such as deep spatiotemporal coupling and dynamic feedback control. Specifically, existing synergistic treatment equipment simply splices together the electrolysis and magnetization devices, which operate independently. They fail to achieve deep integration of the electrolytic electric field and magnetic field in the same physical space in the structural design, nor do they establish a parameter coupling mechanism based on real-time water quality monitoring data to address the characteristics of load changes and dynamic fluctuations in water quality parameters in circulating water systems. This makes it difficult to dynamically adjust the intensity of the electrolytic electric field and the parameters of the magnetic field according to changes in core water quality indicators such as conductivity and calcium and magnesium ion concentration, resulting in significant blind spots in the synergistic treatment process. Summary of the Invention

[0004] To address the technical problem mentioned in the background section regarding the significant synergistic blind spots in current industry solutions that combine electrochemistry and physical magnetization for the synergistic treatment of circulating water, this invention provides a circulating water treatment device and method based on the synergy of electrochemistry and permanent magnet magnetic fields.

Detailed Implementation

[0056] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] In one embodiment, as shown in the appendix Figure 1-5 As shown, this application discloses a circulating water treatment device based on the synergy of electrochemistry and permanent magnet 201 magnetic field, including a cathode shell 1, a spiral magnetic field array 2, a swirling water distribution assembly 3, and a titanium anode 4. Several layers of the spiral magnetic field array 2 are equidistantly arranged on the outer surface of the cathode shell 1. The swirling water distribution assembly 3 is coaxially arranged inside the cathode shell 1. The titanium anode 4 is fixedly installed between the inner wall of the cathode shell 1 and the outer wall of the swirling water distribution assembly 3.

[0058] The single-layer spiral magnetic field array 2 includes a plurality of permanent magnets 201 and a magnetic yoke 202. The plurality of permanent magnets 201 are arranged around the outer wall of the cathode shell 1 at equal angles in the circumference. The magnetic yoke 202 is fixedly sleeved on the outer end of the plurality of permanent magnets 201. The spiral magnetic field array 2 and the adjacent spiral magnetic field array 2 are arranged in a phase-controlled spiral.

[0059] The swirling water distribution assembly 3 includes a cathode inner column 301 coaxially disposed inside the cathode housing 1. One end of the cathode inner column 301 is movably sleeved with a water inlet spiral vortex fan 303, and the other end of the cathode inner column 301 away from the water inlet spiral vortex fan 303 is fixedly disposed with a water outlet spiral vortex fan 304. The outer sides of both the water inlet spiral vortex fan 303 and the water outlet spiral vortex fan 304 are movably abutting against the inner wall of the cathode housing 1.

[0060] The titanium anode 4 is electrically connected to the positive terminal of the electrolysis power supply, and the cathode shell 1 and the cathode inner column 301 are connected in parallel to the negative terminal of the electrolysis power supply. A strong electric field is applied between the outer wall of the titanium anode 4 and the cathode shell 1, and between the inner wall of the titanium anode 4 and the cathode inner column 301.

[0061] In this embodiment, the present application includes four core components: a cathode shell 1, a spiral magnetic field array 2, a swirling water distribution assembly 3, and a titanium anode 4. The outer surface of the cathode shell 1 is arranged with multiple spiral magnetic field arrays 2 at equal intervals. The swirling water distribution assembly 3 is coaxially arranged inside the cathode shell 1. The titanium anode 4 is fixedly installed between the inner wall of the cathode shell 1 and the outer wall of the swirling water distribution assembly 3. The support for fixing the titanium anode 4 is a thin insulating material. The insulating material is used for circuit breaking, and the thin material helps to reduce the impact on the swirling flow. The titanium anode 4 has a columnar mesh structure and is coated with a rare earth composite coating, which is suitable for the treatment characteristics of circulating water with high calcium and magnesium content. The single-layer spiral magnetic field array 2 consists of several permanent magnets 201 and a magnetic yoke 202. The permanent magnets 201 are made of N52 neodymium iron boron material. Several permanent magnets 201 are arranged at equal angles around the outer wall of the cathode shell 1. The magnetic yoke 202 is fixedly sleeved on the outer end of all permanent magnets 201 in this layer. At the same time, the outer layer of the permanent magnets 201 is also provided with an epoxy resin sealing layer. The water inlet and the conductive busbars at both ends of the titanium anode 4 are set as non-magnetic areas. The two adjacent spiral magnetic field arrays 2 adopt a phase-controlled spiral arrangement to form an axial spiral magnetic field structure. This magnetic field array can generate an axial strong magnetic field of 1.0-1.2T inside the device. The core of the swirling water distribution assembly 3 is the inner cathode column 301 coaxially disposed inside the cathode housing 1. One end of the inner cathode column 301 is movably sleeved with the inlet spiral vortex fan 303, and the other end of the outer wall of the inner cathode column 301 away from the inlet spiral vortex fan 303 is fixedly provided with the outlet spiral vortex fan 304. The outer sides of both the inlet and outlet spiral vortex fans 304 are in movable contact with the inner wall of the cathode housing 1. Annular swirling channels are formed between the cathode housing 1 and the titanium anode 4, and between the titanium anode 4 and the inner cathode column 301. In terms of electrode power supply and electric field setup, the titanium anode 4 is individually electrically connected to the positive terminal of the electrolysis power supply, and the cathode shell 1 and the inner column 301 are connected in parallel to the negative terminal of the electrolysis power supply, forming a single anode and double cathode electrode structure. At the same time, a strong electric field is applied in the two annular flow channels between the titanium anode 4 and the cathode shell 1, and between the titanium anode 4 and the inner column 301 of the cathode. The electric field strength is controlled at 50-150V / m, and the electric field form can be a DC electric field or a high-frequency pulsed DC electric field of 10-50Hz. The cell voltage is controlled at 2.5-4.5V, and the current density is maintained at 100-500A / m². If high-frequency pulsed DC electrolysis is used, the cell voltage is 4.5V-10V, and the current density is still 100-500A / m².

[0062] Specifically, the single-anode, dual-cathode layout forms two annular electrolysis channels, significantly increasing the contact area for the electrolysis reaction. Combined with the rare-earth composite-coated titanium anode 4, this enhances the stability and efficiency of the electrolysis reaction. The axial strong magnetic field and strong electric field are arranged in the same domain, achieving spatiotemporal coupling of electrochemistry and magnetic field, allowing the water flow to simultaneously undergo both magnetic polarization and electrolytic oxidation. Specifically, the anode oxygen and chlorine evolution reactions produce active oxidizing substances. , The combination of HClO and swirling shear force prevents localized cathode passivation, while magnetic field polarization destroys microbial cell membranes, achieving a sterilization rate of ≥99.9% against stubborn microorganisms such as Legionella. Simultaneously, the electric and magnetic fields work together to alter the surface charge state of the metal pipes, inhibiting electrochemical corrosion and under-deposit corrosion. No chemical agents are required, achieving simultaneous sterilization, algae removal, and equipment corrosion inhibition, thus extending equipment lifespan while avoiding chemical pollution. The annular swirling channel, combined with the double-vortex fan structure of the swirling water distribution component 3, allows the water flow to form a stable swirling flow. The effective swirling velocity within the channel can reach 1.5-6 m / s, effectively preventing localized cathode passivation and uneven scaling using fluid shear force, while simultaneously improving the cutting efficiency of the Lorentz force on the fluid. The design of the magnetic yoke 202, epoxy resin sealing layer, and non-magnetic zone effectively reduces magnetic field interference, prevents magnet damage, and ensures stable magnetic field strength output. The flexible setting of the high-frequency pulsed DC electric field can achieve sterilization and algae removal by generating active oxidizing substances through oxygen or chlorine evolution reactions, or by destroying microbial cell membranes through a high-frequency pulsed strong electric field, achieving rapid inactivation. The overall structure abandons the mechanical stacking of traditional equipment, realizing multi-field collaboration in the same physical space, adapting to the treatment needs of high-flow and high-hardness circulating water systems, and providing a solid structural foundation for scale prevention, scale removal, sterilization and corrosion inhibition.

[0063] In one embodiment, the permanent magnets 201 in the single-layer spiral magnetic field array 2 are arranged in alternating polarities on the outer wall of the cathode shell 1; and several permanent magnets 201 in the adjacent spiral magnetic field array 2 are arranged at a clockwise angle along the circumference of the cathode shell 1 to simulate the upward trajectory of the swirling flow inside the cathode shell 1.

[0064] In this embodiment, inside the single-layer spiral magnetic field array 2, several permanent magnets 201 are arranged on the outer wall of the cathode shell 1 in an alternating polarity manner. That is, the permanent magnets 201 evenly distributed along the circumference of the same layer are arranged in a regular pattern with the N pole and S pole alternately attached to the cathode shell 1, without any continuous arrangement of the same polarity. There are 16 permanent magnets 201 evenly distributed in the circumferential direction of the single layer, and the included angle between adjacent permanent magnets 201 is 22.5°. In the spiral magnetic field array 2 of adjacent layers, several permanent magnets 201 are set at a clockwise deflection angle of 9° along the circumference of the cathode shell 1. Each layer of magnets is horizontally offset relative to the previous layer, thereby simulating the upward trajectory of the 45° swirling flow of circulating water inside the cathode shell 1. The spiral magnetic field array 2 has a total of 6 layers in the axial direction. After the multiple layers are stacked, an axial spiral magnetic field that precisely matches the movement trajectory of the swirling water flow is formed. The total number of permanent magnets 201 arrays is 96, which can form a uniform and continuous axial strong magnetic field of 1.0-1.2T inside the device.

[0065] Specifically, the N and S poles of the single-layer permanent magnet 201 are arranged alternately, combined with a design of 16 pieces per layer, evenly distributed at 22.5° angles. This allows the single layer to form a closed and uniform annular magnetic field. The magnetic field lines continuously encircle the circumference of the cathode shell 1, avoiding the problems of local magnetic field concentration and uneven magnetic field strength in the flow channel caused by adjacent elements of the same polarity. This ensures that all positions in the annular swirling flow channel are uniformly covered by a strong magnetic field of 1.0-1.2T, allowing the water flow to be uniformly cut by magnetic polarization, weakening the hydrogen bond network of water molecules and reducing ion bridging and association. The phase-controlled spiral arrangement of adjacent layers at a 9° clockwise angle, combined with the 6-layer axial layout, allows the multi-layer magnetic field array to form an axial spiral magnetic field that perfectly matches the 45° swirling upward trajectory. This ensures that the water flow is continuously subjected to a uniformly polarized alternating magnetic field throughout the entire axial swirling motion within the device, maximizing the cutting efficiency of the Lorentz force on the fluid and further enhancing the water molecule cluster splitting effect. This arrangement design allows for precise matching of the magnetic field with the swirling flow field and the electrolytic electric field in terms of both trajectory and intensity. Even when the conductivity of the circulating water fluctuates significantly between 5-30 mS / cm, the association of hardness ions can still be continuously blocked. This avoids the degradation of scale inhibition effect caused by water quality fluctuations in traditional treatments, achieving long-term stable scale inhibition under dynamic operation of high-hardness circulating water systems. It solves the "penetration" phenomenon in traditional physical magnetic water treatment, where the scale inhibition efficiency drops sharply under conditions of large conductivity fluctuations, high-hardness water, or large-diameter fluid impact due to unreasonable magnetic field arrangement. This significantly improves the scale inhibition effect of physical magnetic polarization, and works in synergy with the electrolytic electric field to block the crystallization association of hardness ions at the source.

[0066] In one embodiment, an inlet guide cone 302 is fixedly provided on one end face of the cathode inner column 301 near the inlet spiral vortex fan 303; the internal blades of the inlet spiral vortex fan 303 and the outlet spiral vortex fan 304 are both designed to be inclined, and their rotation directions are opposite.

[0067] In this embodiment, an inlet guide cone 302 is fixedly installed on the end face of the inner column 301 of the cathode near the inlet spiral vortex fan 303. The guide cone is located at the front end of the inlet spiral vortex fan 303 and directly receives the incoming flow from the inlet end of the device, and is used to pre-divide and pre-guide the water flow. The internal blades of the inlet spiral vortex fan 303 and the outlet spiral vortex fan 304 are both designed with an inclined angle of 45°, and the two blades rotate in completely opposite directions. The inlet spiral vortex fan 303, in conjunction with the tangential water inlet structure of the cathode shell 1, can force the water flow to swirl. The outlet spiral vortex fan 304 is located at the outlet end of the device and is used to rectify the treated swirling water. After being pre-guided by the inlet guide cone 302, the water is forced to swirl by the inlet spiral vortex fan 303, forming a strong swirling flow around the titanium anode 4 in the annular swirling channel. The inlet velocity of the device can be controlled at 3-8 m / s, the effective swirling velocity in the channel is maintained at 1.5-6 m / s, and the residence time of the water in the device is controlled at 5-15 s.

[0068] Specifically, the inlet guide cone 302 pre-guides and pre-divides the axial water flow at the inlet, forcing the axial flow to turn into tangential motion along the annular flow channel. This provides a stable initial flow field for the subsequent swirling and regularization of the 45° inlet spiral turbine fan 303, avoiding turbulence and flow deviation caused by direct impact of the water flow on the turbine fan, improving the uniformity and stability of the swirling flow field, and ensuring that the swirling velocity in the flow channel is stable at 1.5-6 m / s. Both the inlet and outlet turbine fans use 45° inclined blades, which maximizes the guiding effect of the blades. Combined with an inlet flow velocity of 3-8 m / s, this achieves efficient swirling of the water flow, while controlling the water residence time to 5-15 seconds, allowing the water flow to fully contact the electric and magnetic fields, ensuring the treatment effect of electrolysis and magnetic polarization. The two designs, with opposite rotation directions, form a flow field structure where the water inlet swirls and the water outlet is rectified: the inlet spiral vortex fan 303 forcibly converts the axial water inlet into a 45° swirling motion, which, together with the tangential water inlet structure, achieves efficient swirl of the water flow and uses fluid shear force to prevent local passivation of the cathode; the outlet spiral vortex fan 304 orderly rectifies the swirling water body that has completed the electrolysis-magnetic coupling treatment into an axial water flow, avoiding turbulence and energy loss at the outlet, while ensuring a stable output of the activated water body after treatment, so that the water body always maintains a stable swirling state in the device, maximizing the synergistic efficiency of the electrolytic electric field and the axial strong magnetic field.

[0069] In one embodiment, a water distribution end cap 5 is also included. The water distribution end cap 5 is fixedly installed at both ends of the cathode housing 1 for water inlet and outlet. The water distribution end cap 5 is provided with a main flow interface 501 coaxial with the cathode housing 1. The side wall of the water distribution end cap 5 is also provided with an auxiliary interface 502 for real-time water quality detection.

[0070] In this embodiment, two water distribution end caps 5 are fixedly installed at both ends of the cathode housing 1, one end serving as the inlet and the other as the outlet, undertaking the function of circulating water inflow and outflow. A main flow interface 501 is provided on the water distribution end cap 5. This main flow interface 501 is coaxial with the cathode housing 1, serving as the main inflow and outflow channel for circulating water. Combined with the device's annular vortex flow channel, it ensures the high flow rate requirement of circulating water, adapting to the process requirement of an inlet flow velocity of 3-8 m / s. An auxiliary interface 502 is also provided on the side wall of the water distribution end cap 5. This interface is a dedicated interface for online water quality monitoring, where a high-precision sensor array can be installed to achieve real-time acquisition of core water quality parameters of the circulating water, including conductivity, pH value, ORP (oxidation-reduction potential), water temperature, and instantaneous flow rate.

[0071] Specifically, the axial main flow interface 501 of the water supply end cap is designed to accommodate inlet flow velocities of 3-8 m / s, meeting the high-flow-rate processing needs of central air conditioning and industrial circulating water systems, avoiding flow restriction. It also connects with the inlet guide cone 302 and the inlet spiral vortex fan 303 to ensure effective swirling. The side wall auxiliary interface 502 provides a dedicated structural foundation for online water quality monitoring, allowing direct installation of a high-precision sensor array to collect core water quality parameters such as conductivity and pH value. This enables real-time monitoring of the device's treatment effect, facilitating timely detection of system malfunctions and further enhancing the device's intelligence and ease of maintenance.

[0073] S10: The edge computing unit collects multi-dimensional raw water quality information, processes and extracts water quality characteristic parameters, and then uploads it to the central control unit of the Internet of Things architecture.

[0077] S50: The edge computing unit locally stores the entire process operation data, while the central control unit of the IoT architecture enables cloud uploading and remote interaction.

[0078] In this embodiment, the multidimensional water quality raw information refers to the raw data related to the circulating water quality directly collected by sensors without any processing; the water quality characteristic parameters refer to the parameters extracted and calculated from the multidimensional water quality raw information, which can reflect the core state of the circulating water quality; the electrolysis parameters are the key technical parameters for regulating the electrolysis reaction process of the circulating water, which directly affect the strength and effect of the electrolysis electric field; the electrolysis output refers to the electrolysis-related operating parameters actually output by the electrolysis power supply module according to the adjustment command, which is an indicator reflecting the actual operating state of the electrolysis reaction.

[0079] Specifically, the control system employs an edge computing unit and an IoT architecture central control unit to achieve hierarchical control. First, the edge computing unit collects multi-dimensional raw water quality information from the circulating water system, processes it, extracts water quality characteristic parameters reflecting the core state of the water, and uploads these parameters to the IoT architecture central control unit. Next, the IoT architecture central control unit analyzes and decides on the system's operating mode based on the received water quality characteristic parameters, generates control commands adapted to the coordinated operation of electrolysis and magnetic fields, and sends them downwards. Subsequently, the IoT architecture central control unit adjusts electrolysis-related parameters according to these coordinated control commands, and continuously adjusts the electrolysis output through closed-loop correction until it matches the preset requirements of the commands. Then, the IoT architecture central control unit establishes a linkage with the circulating water system's flow inverter to execute equipment self-maintenance control operations, while simultaneously monitoring the system's operating status in real time and providing feedback on relevant information. Finally, the edge computing unit stores the entire system's operating data locally, while the IoT architecture central control unit uploads the relevant data to the cloud and enables interaction with remote terminals. By using edge computing units to complete local data acquisition and processing, rapid response to water quality information is achieved, avoiding delays caused by long-distance data transmission and meeting the real-time control requirements of circulating water systems. Subsequent decision-making, control, linkage, and remote interaction are completed through the central control unit of the Internet of Things architecture, realizing centralized and automated management and control of the system. This solves the problems of lagging control, independent operation of each module without coordination, and the need for manual on-site operation in traditional circulating water treatment equipment. It lays the framework foundation for the refined control of subsequent steps and realizes the intelligentization of the entire process of circulating water treatment system from data acquisition to remote operation and maintenance, improving the system's operational stability and ease of maintenance.

[0080] In one embodiment, as shown in the appendix Figure 7 As shown, step S10 includes the following steps:

[0081] S101: The edge computing unit collects multi-dimensional raw water quality information such as conductivity, pH value, redox potential, water temperature and instantaneous flow rate at a millisecond-level sampling frequency through a high-precision sensor array in the pipeline network.

[0082] S102: The edge computing unit collects multi-dimensional raw water quality information, performs digital filtering after analog-to-digital conversion, removes abnormal jumps and high-frequency noise, and obtains effective water quality information;

[0083] S103: The edge computing unit extracts the real-time conductivity value based on effective water quality information, calculates its rate of change and the mean and standard deviation within a preset time window, forms water quality characteristic parameters, and uploads them to the central control unit of the Internet of Things architecture.

[0084] In this embodiment, conductivity is the core indicator reflecting the ion concentration in circulating water. Its value change directly reflects the concentration factor of circulating water and is a key basis for judging the risk of scaling and corrosion in circulating water. pH value is an indicator reflecting the acidity or alkalinity of circulating water, affecting the existence form of calcium and magnesium ions in water and the efficiency of electrolysis reaction, and is an important parameter for water quality monitoring. Oxidation-reduction potential (ORP) is an indicator reflecting the oxidation-reduction capacity of circulating water, which can judge the risk of microbial growth and the effect of oxidation and sterilization in water, and adapt to the system's sterilization and algae control requirements. Water temperature refers to the actual temperature of circulating water. Temperature changes affect the ion movement speed, magnetic field polarization effect, and electrolysis reaction rate, and are an auxiliary reference indicator for water quality control. Instantaneous flow rate is the water flow velocity of circulating water in the pipe network at a certain moment. It directly affects the swirling effect of the swirling electrolysis magnetic coupling device and the water residence time, and is a core indicator for system flow field control. Digital filtering processing is the process of applying algorithms to digital shapes... The method of processing raw water quality information can eliminate abnormal data and noise caused by sensor interference and water flow fluctuations. Abnormal jumps are irregular and sudden numerical changes in the raw water quality sensor information. Such data does not reflect the actual state of water quality and must be eliminated. High-frequency noise refers to high-frequency, small-amplitude numerical fluctuations superimposed on the raw water quality sensor information. These are caused by factors such as equipment operation interference and will affect the accuracy of water quality analysis. Valid water quality information, after digital filtering to remove invalid data, can truly reflect the actual water quality state of the circulating water and is the basis for extracting water quality characteristic parameters. The conductivity change rate is the amplitude of conductivity change per unit time, which can reflect the trend of ion concentration change in the circulating water and determine whether the water quality tends to be concentrated or diluted. The preset time window is a data analysis time interval set in advance according to the operating characteristics of the central air conditioning circulating water system to adapt to the rhythm of water quality changes in the system.

[0085] Specifically, the edge computing unit uses a high-precision sensor array deployed in the circulating water network to simultaneously collect multi-dimensional raw water quality information such as conductivity, pH value, oxidation-reduction potential, water temperature, and instantaneous flow rate at an ultra-high frequency sampling rate. The edge computing unit then performs analog-to-digital conversion on the collected raw water quality information, converting it into a digital signal and performing digital filtering to remove abnormal fluctuations and high-frequency noise, obtaining effective water quality information that accurately reflects the actual state of the circulating water. Finally, based on this effective water quality information, the edge computing unit extracts the real-time conductivity value, calculates the conductivity change rate, and the mean and standard deviation of conductivity within a preset time window, integrates these parameters to form water quality characteristic parameters, and uploads these parameters to the central control unit of the IoT architecture. Through analog-to-digital conversion and digital filtering, invalid interference data is eliminated, ensuring the authenticity of the water quality information. By extracting and calculating core characteristic parameters related to conductivity, the key to circulating water quality control is grasped, avoiding redundant analysis of multi-dimensional data and improving the efficiency and accuracy of subsequent decision-making.

[0091] Specifically, the central control unit of the IoT architecture receives water quality characteristic parameters uploaded by the edge computing unit. First, it compares the real-time conductivity value with pre-set upper and lower conductivity thresholds to obtain a conductivity range determination result. Next, based on the conductivity change rate in the water quality characteristic parameters, it analyzes and determines the water quality change trend of the circulating water to obtain a conductivity change trend determination result. Then, it combines these two determination results to decide on the system operation mode. Finally, based on the decision result, it generates corresponding operation mode instructions for energy saving and low carbon emissions, high frequency and high efficiency, or smooth transition and fine-tuning, and converts these operation mode instructions into directly identifiable collaborative control instructions adapted to the coordinated operation of electrolysis and magnetic fields, sending them down to the execution module. By comparing real-time conductivity values ​​with threshold values, accurate determination of the current water quality risk level is achieved. By combining the conductivity change rate to judge water quality trends, prediction of water quality changes is achieved, avoiding delayed control. By integrating the two results to make operational mode decisions, collaborative control commands adapted to different water quality states are generated, realizing intelligent and dynamic switching of system operation modes. This solves the problem of traditional circulating water treatment equipment operating at constant power and unable to dynamically adjust according to water quality, avoiding energy waste when the water quality is low-risk and insufficient treatment effect when the water quality is high-risk. At the same time, it ensures the coordinated matching of electrolysis and magnetic field, laying the foundation for subsequent fine adjustment of electrolysis parameters and improving the system's energy efficiency and the stability of treatment effect.

[0094] S302: The central control unit of the IoT architecture continuously monitors the actual output voltage and current of the electrolytic power module and obtains electrolytic output feedback information;

[0095] S303: The central control unit of the IoT architecture compares the electrolysis output feedback information with the set value of the electrolysis adjustment command, and performs closed-loop correction until the actual output matches the set value.

[0097] Specifically, the central control unit of the IoT architecture sends electrolysis adjustment commands to the electrolysis power supply module, including voltage setpoints, current density setpoints, and operating frequency setpoints, based on the coordinated control instructions, thus specifying the target operating parameters of the electrolysis power supply. Then, the central control unit continuously and in real-time monitors the actual output voltage and current of the electrolysis power supply module, collecting and generating electrolysis output feedback information. Finally, the central control unit compares the collected electrolysis output feedback information with each parameter setpoint in the electrolysis adjustment commands, continuously adjusting the electrolysis adjustment commands based on the comparison results, executing a closed-loop correction operation until the actual output of the electrolysis power supply module matches the setpoints. This closed-loop correction method ensures that the actual output of the electrolysis power supply is consistent with the preset command requirements, avoiding deviations in electrolysis parameters caused by equipment operation errors or water quality fluctuations.

[0098] In one embodiment, as shown in the appendix Figure 10 As shown, step S40 includes the following steps:

[0099] S401: The central control unit of the Internet of Things architecture acquires flow control information, including the operating frequency of water pumps and the flow rate of the pipeline network, in real time based on the flow frequency converter;

[0100] S402: The central control unit of the Internet of Things architecture monitors the electrolytic output feedback information. When the output current abnormally decreases and exceeds the preset threshold under the same voltage, it determines the cathode scaling and generates scaling determination information.

[0101] S403: The central control unit of the Internet of Things architecture sends a flow rate increase command to the flow inverter based on the scaling determination information, and controls it to increase the water pump operating frequency to the preset flushing flow rate and maintain it for the preset duration.

[0102] S404: After flushing, the central control unit of the IoT architecture sends a flow rate recovery command to the flow inverter to control it to reset the pump operating frequency to the original set value.

[0103] S405: The central control unit of the IoT architecture re-monitors the electrolysis output feedback information and records the self-cleaning success event or generates manual maintenance requirement information according to whether the parameters have recovered.

[0104] In this embodiment, the pump operating frequency is the actual operating frequency of the pumps in the circulating water system, which is the core indicator for regulating the water flow velocity in the pipe network and directly affects the inlet flow velocity of the vortex electrolysis magnetic coupling device; the pipe network flow rate is the actual flow rate of the circulating water in the entire pipe network, reflecting the actual state of the water flow velocity and serving as a reference indicator for flow control; the flow control information is formed by collecting parameters such as the pump operating frequency and pipe network flow rate, reflecting the information of the circulating water flow field state; abnormal output current attenuation refers to a significant drop in the output current of the electrolysis power module without reasonable cause under constant voltage, which is a typical characteristic of cathode scaling; the preset attenuation threshold is the critical amplitude of output current attenuation set in advance according to the equipment operating characteristics, and is a quantitative standard for determining whether the cathode has scaled; cathode scaling refers to the phenomenon that minerals such as calcium and magnesium ions in the circulating water deposit on the cathode surface of the vortex electrolysis magnetic coupling device, forming a scale layer, which leads to a decrease in electrolysis efficiency and electrode passivation; scaling The judgment information refers to the conclusion reached by the central control unit of the IoT architecture based on the electrolysis output feedback information after determining that scale has formed on the cathode. This conclusion serves as the basis for issuing self-maintenance commands. The flow rate increase command is a control command issued by the central control unit of the IoT architecture to the flow inverter, requesting an increase in the flow rate of the pipeline water. The preset flushing flow rate is the minimum water flow rate that can physically flush the scale layer on the cathode surface, pre-set according to the structural characteristics of the vortex electrolysis magnetic coupling device. The preset flushing duration is the shortest flushing time that can effectively remove the scale layer on the cathode surface, pre-set according to the test data of the scale flushing effect. The flow rate recovery command is a control command issued by the central control unit of the IoT architecture to the flow inverter, requesting that the flow rate of the pipeline water be restored to the value set before the scale determination. The manual maintenance requirement information refers to the prompt information generated after the cathode flushing is completed, if the electrolysis output parameters still have not returned to normal, and it is determined that the scale layer cannot be removed by physical flushing, requiring manual intervention and maintenance.

[0105] Specifically, the central control unit of the IoT architecture first establishes a bidirectional communication connection with the flow inverter of the circulating water system to collect flow control information such as pump operating frequency and pipeline flow in real time, and grasp the real-time status of the flow field. During the electrolysis parameter adjustment process, it continuously monitors the electrolysis output feedback information. When it detects that the output current abnormally decreases and the decrease exceeds the preset decrease threshold while the electrolysis power supply output voltage setting remains unchanged, it determines that scaling has occurred on the cathode surface and generates scaling determination information. Then, based on the scaling determination information, it sends a flow rate increase command to the flow inverter to control the flow inverter. The system increases the operating frequency of the water pump, raising the inlet flow rate of the vortex electrolysis magnetic coupling device to a preset flushing velocity and maintaining this velocity for a preset flushing time. This enhanced vortex shear force enables physical self-cleaning of the cathode surface. After the flushing time, the central control unit of the IoT architecture sends a flow rate recovery command to the flow inverter, controlling it to reset the water pump operating frequency to the original set value before scaling was determined. Finally, the system re-monitors the electrolysis output feedback information in real time, recording a successful self-cleaning event or generating and recording manual maintenance requirements based on whether the electrolysis output parameters have returned to the normal range. By establishing a communication connection with the flow inverter, the electrolysis system and the flow field system are linked, making the vortex flow rate a control method for equipment self-maintenance and fully utilizing the vortex structural characteristics of the device. By monitoring the electrolysis output feedback information to determine cathode scaling, automatic and accurate scaling identification is achieved, avoiding omissions and delays in manual inspections, delaying electrode passivation, extending equipment lifespan, and ensuring the long-term stable operation of the electrolysis system.

[0111] Specifically, the edge computing unit locally stores all data generated throughout the system's operation, including water quality sensor information, characteristic parameters, various control commands, operational feedback information, and event records. This data is then integrated and organized into a system operation log, enabling local data traceability. Simultaneously, the IoT architecture's central control unit, through its own IoT communication module, uploads key data and alarm information from the system operation log to a remote cloud monitoring platform. It also establishes communication protocols with the central air conditioning room control system, facilitating data exchange and allowing staff to remotely monitor the system's operational status. Finally, the IoT architecture's central control unit receives real-time remote commands from the cloud monitoring platform or the central control system and executes operations such as switching operating modes, adjusting parameter thresholds, or resetting the system. Upon completion, it promptly reports the remote interaction execution status back to the platform system that issued the command. By using the edge computing unit to achieve local storage of all process data and generate system operation logs, data traceability is ensured even in the event of network outages or cloud failures, providing data support for equipment fault diagnosis and operational performance analysis. Furthermore, the IoT architecture's central control unit uploads key data and alarm information to the cloud, enabling remote data storage and real-time monitoring.

[0112] A specific embodiment of the circulating water treatment device and method based on the synergy of electrochemistry and permanent magnet magnetic field of the present invention is as follows:

[0113] After the circulating water treatment control system is started, the high-precision sensor array on the auxiliary interface of the water distribution end cap side wall collects parameters such as the conductivity, pH value, ORP oxidation-reduction potential, water temperature, and instantaneous flow rate of the circulating water. The edge computing unit receives this multi-dimensional raw water quality information at a millisecond frequency. After analog-to-digital conversion and digital filtering to remove abnormal data and high-frequency noise, it extracts water quality characteristic parameters such as the real-time conductivity value, rate of change, and mean and standard deviation within a preset time window, and then uploads them to the central control unit of the IoT architecture. After receiving the parameters, the central control unit of the IoT architecture compares the real-time conductivity value with preset upper and lower thresholds, determines the water quality change trend based on the conductivity rate of change, and completes the operation mode decision based on the comprehensive results. It generates corresponding operation mode commands for energy saving and low carbon, high frequency and high efficiency, or smooth transition and fine adjustment, and converts them into electrolysis and magnetic field coordinated control commands for issuance. Next, the central control unit of the IoT architecture sends electrolysis adjustment commands containing voltage, current density, and operating frequency setpoints to the electrolysis power supply module according to the collaborative control commands. At the same time, it continuously monitors the actual output voltage and current of the electrolysis power supply module, compares the electrolysis output feedback information with the setpoints, and performs closed-loop correction until the actual output matches the setpoints. At this time, the titanium anode is connected to the positive terminal of the power supply, and the cathode shell and the inner column of the cathode are connected in parallel to the negative terminal. A strong electric field of 50-150V / m is formed in the two annular swirling flow channels, which achieves co-domain synergy with the 1.0-1.2T axial strong magnetic field formed by the 6 layers of phase-controlled spiral permanent magnets outside the cathode shell. The circulating water enters the device through the main flow interface of the water distribution end cap. It is first pre-diverted and guided by the inlet guide cone, and then forced to swirl by the 45° inlet spiral vortex fan. It enters the annular flow channel at an inlet flow velocity of 3-8 m / s, forming a stable vortex flow of 1.5-6 m / s. The water stays in the device for 5-15 seconds. Under the triple action of the swirling flow field, strong electric field, and strong axial magnetic field, the water molecule clusters are polarized and broken down, sterilized and algaed, and hardness ion adsorbed. After treatment, the water is rectified by the 45° outlet spiral vortex fan with the opposite rotation direction and then output to the circulating water system through the main flow interface of the outlet water distribution end cap. During the process, the central control unit of the IoT architecture maintains real-time communication with the flow inverter to obtain information such as the pump operating frequency and pipeline flow, and continuously monitors the electrolysis output feedback information. When abnormal attenuation of the output current under the same voltage is detected and exceeds the preset threshold, it is determined that the cathode is scaled and a flow rate increase command is sent to the flow inverter to control it to increase the pump operating frequency to the preset flushing flow rate and maintain it for a preset duration. The enhanced swirling shear force is used to physically self-clean the cathode surface. After the flushing is completed, a flow rate recovery command is sent to reset the pump frequency to the original value, and then the electrolysis output parameters are monitored again. The self-cleaning success event or manual maintenance request information is recorded according to whether the parameters are restored.Throughout the entire process, the edge computing unit stores all data locally, including water quality sensor information, characteristic parameters, control commands, operational feedback information, and event records, and integrates them to generate a system operation log. The central control unit of the IoT architecture uploads key data and alarm information from the operation log to the cloud monitoring platform through the IoT communication module. At the same time, it achieves protocol interoperability and data interaction with the central air conditioning room control system. After receiving remote commands from the cloud platform or the central control system, it performs operation mode switching, parameter threshold adjustment, or system reset operations, and promptly provides feedback on the remote interaction execution status.
