Description

Technical Field

[0001] This application relates to the field of water treatment, and in particular to a broadband tunable electromagnetic field water treatment method, system, platform, and storage medium. Background Technology

[0002] Industrial circulating water systems, central air conditioning systems, boilers, and heating networks are prone to scaling, algae growth, and equipment corrosion during operation, severely impacting heat exchange efficiency, increasing energy consumption, and shortening equipment lifespan. Electromagnetic water treatment technology, as a physical water treatment method that requires no chemical additives, is environmentally friendly, and easy to install, can achieve scale inhibition, scale removal, sterilization, and corrosion inhibition functions, making it an important technological direction to replace traditional chemical treatments.

[0003] Existing electromagnetic water treatment devices mostly employ fixed-frequency or narrow-band electromagnetic field generation structures and utilize single-point energy output modes. Due to the limited frequency coverage, reliance on manual parameter adjustment, and lack of intelligent feedback mechanisms in existing electromagnetic water treatment equipment, they suffer from low energy coupling efficiency, unstable water treatment effects, uneven energy distribution, inability to quantify and monitor effects, and a lack of remote intelligent control. Consequently, they fail to meet the practical needs of industrial scenarios for wide-range operating conditions, long-term stable operation, and intelligent operation and maintenance. Summary of the Invention

[0004] To improve the stability of electromagnetic water treatment effects, this application provides a broadband adjustable electromagnetic field water treatment method, system, platform, and storage medium.

[0005] In a first aspect, this application provides a broadband tunable electromagnetic field water treatment method, which adopts the following technical solution: A broadband tunable electromagnetic field water treatment method includes: Acquire and preprocess water quality information, which includes at least the raw signals and operating condition signals of conductivity, temperature, pH, redox potential, and other parameters. The raw water quality information and operating condition signals are sent and preprocessed to output scaling trends and operating condition characteristics. The preprocessing includes at least analog signal preprocessing, digital signal preprocessing and system process preprocessing. Broadband electromagnetic field generation and coupling receive the raw signals and operating condition signals of pre-processed water quality information, and generate a continuously adjustable pulsed electromagnetic field to activate water molecules and regulate the crystallization morphology of calcium carbonate; the range of the pulsed electromagnetic field is 80Hz to 1000KHz. Effect monitoring and post-processing: The water quality after water molecule activation and calcium carbonate crystallization morphology regulation is judged based on a preset monitoring frequency to obtain monitoring data. The monitoring data is combined with offline scale morphology and corrosion rate detection to form a verification system. Post-processing is performed according to the verification system, wherein the post-processing includes at least automatic sewage discharge, side-stream filtration, exhaust gas, and sediment discharge.

[0006] By employing the above technical solution, multi-dimensional sensors are used to collect water quality information in real time, and the information is pre-processed to remove interference, accurately analyzing the current scaling trend and operating characteristics. Based on this analysis, the system can intelligently generate a continuously adjustable pulsed electromagnetic field within an ultra-wide frequency band of 80Hz to 1000KHz. This wide-frequency adjustable electromagnetic field can select the optimal operating frequency band for different water quality conditions, thereby more effectively activating water molecules and precisely controlling the crystallization morphology of calcium carbonate, causing it to form loose sludge that is not easily attached to metal surfaces. Finally, through a verification system combining online monitoring and offline detection, the water treatment effect can be quantitatively evaluated, and post-treatment actions such as sewage discharge and filtration can be automatically triggered, forming a complete closed-loop control. This significantly improves the energy coupling efficiency between the electromagnetic field and water, ensuring the stability and reliability of the water treatment effect.

[0007] Optionally, the preprocessing includes at least analog signal preprocessing, digital signal preprocessing, and system process preprocessing; The digital signal preprocessing includes at least outlier removal, determining whether the original signal is within a preset valid signal range, and marking the original signal outside the valid signal range as invalid if the original signal is not within the valid signal range. The valid signal range is an interval with an upper and lower limit set to remove original signals with obvious jumps caused by bubbles or transient interference.

[0008] By adopting the above technical solution, a signal validity judgment mechanism is introduced in the early stage of data processing. By setting upper and lower limits for the signal, interference data caused by non-operating factors such as air bubbles in the water flow and instantaneous fluctuations of the sensor can be effectively filtered out, preventing these "dirty data" from misleading subsequent scaling trend analysis and electromagnetic field parameter decisions, thereby improving the anti-interference capability and control accuracy of the entire system.

[0009] Optionally, each original signal is numbered sequentially, and the original signals marked as invalid values ​​are included in a preset invalid value analysis library. The number of each original signal entered into the invalid value analysis library is compared with the number of the previous original signal to obtain the number difference, and the number difference is compared with a preset threshold; wherein, the invalid value analysis library is the relationship between the number, the invalid signal, and the number difference with the adjacent number; If the difference in the number is less than the preset threshold, it indicates that there is a continuous jump, and the original signal entered is then marked. Determine whether each tagged original signal is continuous with the other tagged original signals, and determine the number of continuous original signals. If the number of continuous tagged original signals is greater than the preset number N, then issue an alarm signal.

[0010] By adopting the above technical solution, not only are discrete outliers eliminated, but time-series analysis of invalid signals is also performed. When a large number of invalid signals appear consecutively within a short period of time, i.e., the difference in the number is less than a preset threshold and the number of consecutive signals exceeds N, the system will determine that it is not an occasional interference, but rather that the sensor may be malfunctioning or that there is a serious anomaly in the water body, and will issue an alarm in a timely manner. The diagnosis from the data layer to the operating condition layer improves the system's security and ease of operation and maintenance.

[0011] Optionally, a broadband electromagnetic field is generated and coupled to receive the raw signals and operating condition signals of the pre-processed water quality information, and to generate a continuously adjustable pulsed electromagnetic field to activate water molecules and regulate the crystallization morphology of calcium carbonate. Calculate the axial magnetic field strength at the center of the pipe: B = (µ0 * N * I) / D, where B is the electromagnetic induction intensity, and µ0 is the free permeability = 4π * 10⁻⁶. -7 H / m, N is the number of coil turns, I is the coil current (A), and D is the pipe inner diameter (m); calculate the axial magnetic field strength at the center of the control pipe according to the formula; The pulsed electromagnetic field is divided into frequency bands corresponding to sterilization and activation, old scale removal, and high hardness water requirements, respectively; The water treatment energy field is formed by segmenting the broadband output and controlling the axial magnetic field strength at the center of the pipeline.

[0012] By adopting the above technical solution, the complex electromagnetic field control process was quantified and segmented for management. The axial magnetic field strength at the center of the pipeline was calculated to ensure the intensity of the electromagnetic field energy. Simultaneously, the ultra-wide frequency band of 80Hz to 1000kHz was divided into multiple functional sub-bands, such as those for sterilization and activation, scale removal, and high-hardness water treatment. This allows the system to accurately select and output the corresponding frequency band of electromagnetic field based on the specific operating conditions analyzed during pretreatment, further improving energy utilization efficiency and treatment effectiveness in water treatment.

[0013] Optionally, effect monitoring and post-processing are performed. The water quality after water molecule activation and calcium carbonate crystallization morphology regulation is judged based on a preset monitoring frequency to obtain monitoring data. The monitoring data is combined with offline scale morphology and corrosion rate detection to form a verification system. The pressure difference between the heat exchanger inlet and outlet and the filter is detected at a preset time interval. If the pressure difference increases at the first test, it means that the flow channel has narrowed. Therefore, the descaling efficiency is increased and a second pressure difference test is performed after the preset descaling time interval. If the pressure difference decreases at the second test, it means that the descaling is successful and a discharge command is issued.

[0014] By adopting the above technical solution, differential pressure detection is used as one of the direct feedback mechanisms for evaluating the descaling effect. When an increase in differential pressure is detected, indicating that scale has formed or adhered, the system determines that the flow channel has narrowed and immediately increases the descaling efficiency, for example, by adjusting the electromagnetic field frequency or intensity. After a preset period of intensive treatment, the differential pressure is detected again. If the differential pressure decreases, the descaling is confirmed to be successful, and the detached scale is automatically discharged. This achieves adaptive control and effect verification of the descaling process, reduces blind treatment, and ensures the long-term stable operation of the system.

[0015] Optionally, the pressure difference between the heat exchanger inlet and outlet and the filter before and after the filter is detected once according to a preset time period. If the pressure difference increases in the first detection, it means that the flow channel has narrowed. In this case, the descaling efficiency is increased and a second pressure difference is detected after the preset descaling time period. If the pressure difference decreases in the second detection, it means that the descaling is successful and a discharge command is issued. The pressure difference between the heat exchanger inlet and outlet and the filter is detected at a preset time period. The pressure difference is compared with a preset threshold. If the pressure difference increases and exceeds the threshold, it indicates that the flow channel is narrowing. Therefore, the descaling efficiency is increased and a second pressure difference is detected after a preset descaling time period. If the pressure difference decreases and is less than the preset threshold, it indicates that the descaling is successful and a discharge command is issued.

[0016] By adopting the above technical solution, a threshold judgment mechanism is introduced into the differential pressure feedback control. It not only detects the relative change in differential pressure but also compares it with a preset threshold. Only when the differential pressure rises and exceeds the threshold is the enhanced descaling program initiated, reducing frequent malfunctions caused by minor fluctuations. Simultaneously, the criterion for successful descaling is set as a secondary decrease in differential pressure below the threshold, ensuring that the descaling effect reaches the expected cleanliness standard, rather than merely showing improvement, thereby guaranteeing the system's processing accuracy and reliability.

[0017] Secondly, this application provides a broadband adjustable electromagnetic field water treatment system, which adopts the following technical solution: A broadband adjustable electromagnetic field water treatment system, comprising: The information acquisition module is used to acquire and preprocess water quality information, which includes at least the raw signals and operating condition signals of conductivity, temperature, pH, redox potential, etc. The raw water quality information and operating condition signals are sent and preprocessed to output scaling trends and operating condition characteristics. The preprocessing includes at least analog signal preprocessing, digital signal preprocessing and system process preprocessing. The processing and adjustment module is used for broadband electromagnetic field generation and coupling. It receives the raw signals of pre-processed water quality information and operating condition signals, and generates a continuously adjustable pulsed electromagnetic field to activate water molecules and regulate the crystallization morphology of calcium carbonate. The range of the pulsed electromagnetic field is 80Hz to 1000KHz. The monitoring and processing module is used for effect monitoring and post-processing. It judges the water quality after water molecule activation and calcium carbonate crystallization morphology regulation based on a preset monitoring frequency to obtain monitoring data. The monitoring data is combined with offline scale morphology and corrosion rate detection to form a verification system. Post-processing is performed according to the verification system, wherein the post-processing includes at least automatic sewage discharge, side-stream filtration, exhaust gas, and sediment discharge.

[0018] Thirdly, this application provides a broadband adjustable electromagnetic field water treatment platform, which adopts the following technical solution: A wideband adjustable electromagnetic field water treatment platform is provided, comprising a processor and a memory. The memory stores at least one instruction, at least one program, a code set, or an instruction set. The at least one instruction, the at least one program, and the code set are loaded and executed by the processor to implement the wideband adjustable electromagnetic field water treatment method as described in any one of claims 1 to 6.

[0019] Fourthly, this application provides a computer-readable storage medium, which adopts the following technical solution: A computer-readable storage medium storing at least one instruction, at least one program, a code set, or an instruction set, wherein the at least one instruction, the at least one program, the code set, or the instruction set is loaded and executed by a processor to implement the broadband tunable electromagnetic field water treatment method as described in any one of claims 1 to 6.

[0020] In summary, this application includes at least one of the following beneficial technical effects: In this application, multi-dimensional sensors are used to collect water quality information in real time, and the information is pre-processed to remove interference, accurately analyzing the current scaling trend and operating characteristics. Based on this analysis, the system can intelligently generate a continuously adjustable pulsed electromagnetic field within an ultra-wide frequency band of 80Hz to 1000KHz. This wide-frequency adjustable electromagnetic field can select the optimal operating frequency band for different water quality conditions, thereby more effectively activating water molecules and precisely controlling the crystallization morphology of calcium carbonate, making it form loose sludge that is not easily attached to metal surfaces. Through a verification system combining online monitoring and offline detection, the water treatment effect can be quantitatively evaluated, and post-treatment actions such as sewage discharge and filtration can be automatically triggered, forming a complete closed-loop control. This significantly improves the energy coupling efficiency between the electromagnetic field and water, ensuring the stability and reliability of the water treatment effect. Furthermore, in addition to eliminating discrete outliers, the system also performs time-series analysis on invalid signals. When a large number of invalid signals appear consecutively in a short period of time, i.e., the difference in the number is less than the preset threshold and the number of consecutive signals exceeds N, the system will determine that it is not an occasional interference, but that the sensor may be malfunctioning or the water body is experiencing a serious anomaly, and will issue an alarm in a timely manner. The diagnosis from the data layer to the operating condition layer improves the system's security and ease of operation and maintenance. Furthermore, a threshold judgment mechanism is introduced into the differential pressure feedback control. It not only detects the relative change in differential pressure but also compares it to a preset threshold. Only when the differential pressure rises and exceeds the threshold is the enhanced descaling program initiated, reducing frequent malfunctions caused by minor fluctuations. Simultaneously, the criterion for successful descaling is set as a secondary decrease in differential pressure below the threshold, ensuring that the descaling effect reaches the expected cleanliness standard, rather than merely showing improvement, thereby guaranteeing the system's processing accuracy and reliability.

[0026] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0027] This application discloses a broadband tunable electromagnetic field water treatment method. (Refer to...) Figure 1-3 The wideband adjustable electromagnetic field water treatment method improves the energy coupling efficiency between the electromagnetic field and water, ensuring the stability and reliability of the water treatment effect. The main implementer of this method is the wideband adjustable electromagnetic field water treatment system. The following section will specifically combine... Figure 1-2 This paper describes the specific process of a broadband adjustable electromagnetic field water treatment method.

[0028] S101, Acquire and preprocess water quality information, which includes at least the raw signals and operating condition signals of conductivity, temperature, pH, redox potential, and other parameters. The raw water quality information and operating condition signals are sent and preprocessed to output scaling trends and operating condition characteristics. The preprocessing includes at least analog signal preprocessing, digital signal preprocessing and system process preprocessing.

[0029] In implementation, the system uses an information acquisition module to collect raw water quality signals, including conductivity, temperature, pH, and oxidation-reduction potential (ORP), at a preset sampling frequency (every 5 minutes in this embodiment). In this embodiment, the information acquisition module may include multiple sensors, such as conductivity sensors, temperature sensors, pH sensors, ORP sensors, electromagnetic flow meters, or ultrasonic flow meters. These sensors are installed in the pipes or containers containing the water to be treated to acquire raw signals in real time.

[0030] The acquired raw signals undergo digital signal preprocessing. Preprocessing includes analog signal preprocessing, such as filtering and amplification, amplifying weak electrical signals (e.g., 0-10mV) output by the sensors and filtering out 50Hz power frequency interference using a low-pass filter; digital signal preprocessing, such as outlier removal, converting the signals to digital quantities and performing validity checks; and system flow preprocessing, such as data format conversion, normalizing the data, unifying the units, and aligning it according to timestamps to form a structured data flow system.

[0031] Based on the processed data, the processing and adjustment module analyzes and derives scaling trends and operating characteristics, such as the Langerier Saturation Index (LSI) and operating characteristics such as flow rate and temperature.

[0032] S102 is a broadband electromagnetic field generator and coupler that receives the raw signals of pre-processed water quality information and operating condition signals, and generates a continuously adjustable pulsed electromagnetic field to activate water molecules and regulate the crystallization morphology of calcium carbonate; the range of the pulsed electromagnetic field is 80Hz to 1000KHz.

[0033] In implementation, electromagnetic field parameters are dynamically generated based on the scaling trends and operating conditions observed in the previous step. According to the analysis results, a broadband signal generator is controlled to generate a continuously adjustable pulsed electromagnetic field from 80Hz to 1000kHz, which is coupled into the water body through a coil wound around the outer wall of the pipe. Specifically, when the system determines that the water is of high hardness (calcium hardness > 500 mg / L CaCO3) and LSI > 0.6, the mid-to-high frequency band of 200-400kHz is selected as the main operating frequency band, as this band has a significant effect on regulating the crystal morphology of calcium carbonate.

[0034] S103, Effect Monitoring and Post-treatment: The water quality after water molecule activation and calcium carbonate crystallization morphology regulation is judged based on a preset monitoring frequency to obtain monitoring data. The monitoring data is combined with offline scale morphology and corrosion rate detection to form a verification system. Post-processing is carried out according to the validation system, which includes at least automatic sewage discharge, side-stream filtration, exhaust gas and sediment discharge.

[0035] During implementation, water quality data is received and judgments are made based on a preset frequency. Offline testing data, such as scale morphology and corrosion rate analyzed in the laboratory, can also be acquired to form a verification system. Instructions are issued based on the verification results.

[0036] Specifically, the system monitors the treated water quality during the continuous application of the electromagnetic field. For example, the system is preset to monitor every 2 hours. The system is validated in conjunction with offline detection data. After one week of operation, maintenance personnel collected water samples for laboratory analysis. The results showed an increase in the proportion of aragonite, which is easily carried by water, in the scale crystals, while the content of calcite, which is difficult to remove, decreased significantly. Corrosion detection of the hanging plates showed a decrease in the corrosion rate of the carbon steel hanging plates, far below the national standard. This indicates that both offline and online monitoring data have validated the effectiveness of the water treatment.

[0037] Based on the verification system's judgment results, the system automatically executes post-processing operations, controlling post-processing equipment such as automatic drain valves, bypass filters, vent valves, and sediment discharge devices to complete physical separation and discharge. Specifically, when online monitoring shows a continuous increase in suspended solids concentration, or offline monitoring reports indicate that scale accumulation has reached a certain amount, the system issues a command to open the electric drain valve for automatic drainage, expelling the detached sludge from the system. Simultaneously, the bypass filter is activated to finely filter the circulating water, removing suspended particles. For potentially accumulating gases, the system periodically opens the vent valve to prevent air resistance from affecting heat exchange efficiency. For scale deposited at the bottom, the system activates the sediment discharge device via timed or differential pressure control.

[0038] Optionally, preprocessing includes at least analog signal preprocessing, digital signal preprocessing, and system process preprocessing; Digital signal preprocessing includes at least outlier removal, determining whether the original signal is within a preset valid signal range, and marking the original signal outside the valid signal range as invalid if it is not within the valid signal range. The valid signal range is an interval with upper and lower limits set to remove original signals with obvious jumps caused by bubbles or transient interference.

[0039] Optionally, each original signal is numbered sequentially, and the original signals marked as invalid values ​​are included in a preset invalid value analysis library. The number of each original signal entered into the invalid value analysis library is compared with the number of the previous original signal entered to obtain the number difference. The number difference is then compared with a preset threshold. The invalid value analysis library is the relationship between the number, the invalid signal, and the number difference with the adjacent number. If the difference in the number is less than the preset threshold, it indicates that there is a continuous jump, and the original signal entered is then marked. Determine whether each tagged original signal is continuous with the other tagged original signals, and determine the number of continuous original signals. If the number of continuous tagged original signals is greater than the preset number N, then issue an alarm signal.

[0040] In implementation, each raw signal is assigned a unique number according to the order of acquisition time. In this implementation scheme, the number is named in the format of timestamp + sensor ID. The preset effective signal range not only includes physical upper and lower limits, but can also be dynamically adjusted based on historical data. For example, for a temperature sensor, the effective range can be automatically adjusted to 25-45℃ in summer and 5-25℃ in winter.

[0041] When a signal is marked as invalid, its number is added to the invalid value analysis library. In this embodiment, the invalid value analysis library records the invalid value itself, as well as its occurrence time, sensor type, and the difference in number between it and the previous invalid value.

[0042] Specifically, in order to further enhance the effect of invalid values, a preset threshold is set in advance. This preset threshold is expressed as a difference in numbers of less than 10, which means that invalid values ​​appear consecutively within 10 collection cycles.

[0043] When the difference between the numbers of two consecutive invalid values ​​in the invalid value analysis library is less than 10, the system marks these invalid values. The system determines whether the marked invalid signals are consecutive and counts the number of consecutive signals. Assume a preset number N=5. If the system detects six consecutive temperature signals marked as invalid, it determines that the sensor is continuously malfunctioning or that there is a drastic anomaly in the water. The system immediately issues an audible or text alarm stating "Temperature sensor may be malfunctioning, please check immediately," and can push this alarm to the mobile phones of maintenance personnel via a 4G / 5G module. This mechanism effectively avoids false alarms caused by occasional sensor drift or transient interference, ensuring the accuracy of the alarm.

[0044] Optionally, a broadband electromagnetic field is generated and coupled to receive the raw signals and operating condition signals of the pre-processed water quality information, and to generate a continuously adjustable pulsed electromagnetic field to activate water molecules and regulate the crystallization morphology of calcium carbonate. Calculate the axial magnetic field strength at the center of the pipe: B = (µ0 * N * I) / D, where B is the electromagnetic induction intensity, and µ0 is the free permeability = 4π * 10⁻⁶. -7H / m, N is the number of coil turns, I is the coil current (A), D is the pipe inner diameter (m); calculate the axial magnetic field strength at the center of the control pipe according to the formula; The pulsed electromagnetic field is divided into frequency bands corresponding to sterilization and activation, old scale removal, and high hardness water requirements, respectively; The water treatment energy field is formed by segmenting the broadband output and controlling the axial magnetic field strength at the center of the pipeline.

[0045] In practice, the broadband frequency is divided into a sterilization and activation band (80Hz~5KHz), a scale removal band (5KHz~50KHz), and a high hardness water treatment band (50KHz~1000KHz). Based on the original signal and operating condition signal of the pre-treated water quality information, the pulse electromagnetic field is adjusted to correspond to the water quality condition, thereby making the water treatment operation more efficient.

[0046] Optionally, effect monitoring and post-processing are performed. The water quality after water molecule activation and calcium carbonate crystallization morphology regulation is judged based on a preset monitoring frequency to obtain monitoring data. The monitoring data is combined with offline scale morphology and corrosion rate detection to form a verification system. The pressure difference between the heat exchanger inlet and outlet and the filter is detected at a preset time interval. If the pressure difference increases at the first test, it means that the flow channel has narrowed. Therefore, the descaling efficiency is increased and a second pressure difference test is performed after the preset descaling time interval. If the pressure difference decreases at the second test, it means that the descaling is successful and a discharge command is issued.

[0047] Optionally, the pressure difference between the heat exchanger inlet and outlet and the filter before and after the filter is detected once according to a preset time period. If the pressure difference increases in the first detection, it means that the flow channel has narrowed. In this case, the descaling efficiency is increased and a second pressure difference is detected after the preset descaling time period. If the pressure difference decreases in the second detection, it means that the descaling is successful and a discharge command is issued. The pressure difference between the heat exchanger inlet and outlet and the filter is detected once within a preset time period. The pressure difference is compared with a preset threshold. If the pressure difference increases and exceeds the threshold, it means that the flow channel has narrowed. Therefore, the descaling efficiency is increased and a second pressure difference is detected after the preset descaling time period. If the pressure difference decreases and is less than the preset threshold, it means that the descaling is successful and a discharge command is issued.

[0048] During implementation, the system is set to perform differential pressure detection on the heat exchanger inlet and outlet or before and after the filter once every preset time period (e.g., every 4 hours). The initial differential pressure of the heat exchanger is 0.1 bar. After running for a period of time, if the system detects a differential pressure increase to 0.2 bar, it can be determined that the flow channel has narrowed due to scaling or blockage. At this time, the system will respond and automatically increase the descaling efficiency.

[0049] Specifically, this implementation plan sets preset thresholds to reduce invalid operations caused by minor fluctuations.

[0050] Assume the system is set with a differential pressure rise threshold ΔP = 0.05 bar and a differential pressure decrease target threshold ΔP = 0.12 bar. When the system detects a differential pressure rise from 0.10 bar to 0.16 bar, the rise of 0.06 bar exceeds the preset threshold of 0.05 bar. The system then determines that the flow channel is indeed blocked, rather than fluctuating normally, and immediately activates the descaling mode.

[0051] After a preset time period, a second differential pressure test is performed. The system only confirms successful descaling when the secondary differential pressure drops below 0.12 bar. If the secondary differential pressure decreases but remains above 0.13 bar (still higher than the target threshold), the system will determine that descaling is incomplete and automatically add an extra descaling cycle until the desired effect is achieved.

[0052] This application also discloses a broadband adjustable electromagnetic field water treatment system. (Refer to...) Figure 2-3 The wideband adjustable electromagnetic field water treatment system includes: Information acquisition module 1 is used to acquire and preprocess water quality information, which includes at least the raw signals and operating condition signals of conductivity, temperature, pH, redox potential, etc. The raw water quality information and operating condition signals are sent and preprocessed to output scaling trends and operating condition characteristics. The preprocessing includes at least analog signal preprocessing, digital signal preprocessing and system process preprocessing.

[0053] The processing and adjustment module 2 is used for broadband electromagnetic field generation and coupling. It receives the raw signal and operating condition signal of the pre-processed water quality information and generates a continuously adjustable pulse electromagnetic field to activate water molecules and regulate the crystallization morphology of calcium carbonate. The range of the pulse electromagnetic field is 80Hz to 1000KHz.

[0054] The monitoring and processing module 3 is used for effect monitoring and post-processing. It judges the water quality after water molecule activation and calcium carbonate crystallization morphology regulation based on a preset monitoring frequency to obtain monitoring data. The monitoring data is combined with offline scale morphology and corrosion rate detection to form a verification system. Post-processing is carried out according to the validation system, which includes at least automatic sewage discharge, side-stream filtration, exhaust gas and sediment discharge.

[0055] The information acquisition module 1 is also used for digital signal preprocessing, including at least outlier removal, determining whether the original signal is within a preset valid signal range, and marking the original signal outside the valid signal range as invalid if the original signal is not within the valid signal range. The valid signal range is an range with upper and lower limits set to remove original signals with obvious jumps caused by bubbles or transient interference.

[0056] The information acquisition module 1 is also used to number each original signal sequentially, and the original signals marked as invalid values ​​are included in the preset invalid value analysis library. The number of each original signal entered into the invalid value analysis library is compared with the number of the previous original signal entered to obtain the number difference. The number difference is then compared with a preset threshold. The invalid value analysis library is the relationship between the number, the invalid signal, and the number difference with the adjacent number. If the difference in the number is less than the preset threshold, it indicates that there is a continuous jump, and the original signal entered is then marked. Determine whether each tagged original signal is continuous with the other tagged original signals, and determine the number of continuous original signals. If the number of continuous tagged original signals is greater than the preset number N, then issue an alarm signal.

[0057] The processing and adjustment module 2 is also used to calculate the axial magnetic field strength at the center of the pipe, B = (µ0 * N * I) / D, where B is the electromagnetic induction intensity and µ0 is the vacuum permeability = 4π * 10⁻⁶. -7 H / m, N is the number of coil turns, I is the coil current (A), and D is the pipe inner diameter (m); calculate the axial magnetic field strength at the center of the control pipe according to the formula; The pulsed electromagnetic field is divided into frequency bands corresponding to sterilization and activation, old scale removal, and high hardness water requirements, respectively; the water treatment energy field is formed by controlling the axial magnetic field strength of the pipeline center based on the segmented wideband output.

[0058] The monitoring and processing module 3 is also used to detect the pressure difference between the heat exchanger inlet and outlet and the filter before and after the preset time period. If the pressure difference increases, it means that the flow channel is narrowed. Therefore, the descaling efficiency is increased and a second pressure difference is detected after the preset descaling time period. If the pressure difference decreases in the second detection, it means that the descaling is successful and a discharge command is issued.

[0059] The monitoring and processing module 3 is also used to detect the pressure difference between the heat exchanger inlet and outlet and the filter before and after a preset time period. The pressure difference is compared with the preset threshold. If the pressure difference increases and exceeds the threshold, it means that the flow channel is narrowed. The descaling efficiency is increased and a second pressure difference is detected after the preset descaling time period. If the pressure difference decreases and is less than the preset threshold, it means that the descaling is successful and a discharge command is issued.
