Description

Technical Field

[0001] The present invention relates to the technical field of seawater desalination treatment, and particularly to a high-pressure soft water medium treatment and supply system. Background Art

[0002] Seawater desalination technology is an important way to solve the shortage of fresh water resources. The traditional processes dominated by distillation method and reverse osmosis membrane method have significant bottlenecks. The distillation method relies on the phase change of high-temperature steam to separate salts, which has problems of high energy consumption and serious equipment corrosion. Moreover, insoluble scale is easily generated during the condensation process, resulting in a significant decrease in heat exchange efficiency. Although the reverse osmosis technology has advantages in treating low-salinity seawater, its core membrane module is sensitive to high-concentration calcium and magnesium ions, and is easily blocked frequently due to fouling or organic pollution. It needs to be shut down periodically for cleaning and the membrane replacement cost is high.

[0003] Existing solutions such as the addition of chemical scale inhibitors can delay scaling in the short term, but the drug residues bring ecological risks and increase the burden of backend treatment. Physical cleaning technologies such as high-pressure water jet can remove deposits on the pipe wall, but the system needs to be shut down during operation, and it is impossible to avoid mechanical damage to the membrane or pipe wall caused by the impact force. Electrochemical methods such as capacitive deionization technology are easily saturated quickly when treating high-hardness seawater due to limited adsorption capacity, and it is difficult to balance the energy consumption and operation complexity during the regeneration process.

[0004] The above technologies generally have problems in actual applications that it is difficult to balance the treatment efficiency and operation cost, especially the insufficient adaptability to high-salinity and high-hardness seawater, which has become the key obstacle restricting large-scale applications. There is an urgent need to develop a collaborative treatment system integrating ion selective adsorption, dynamic removal of deposits and energy recycling to break through the efficiency barrier of traditional processes and achieve sustainable operation.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0030] Referring to Figure 1 , an embodiment of the present invention provides a high-pressure soft water medium treatment and supply system, which adopts the technology of synergistic treatment of electric field dynamic coupling adsorption and fluid shock wave, can achieve high-efficiency ion capture, dynamic removal of sediments, and waste heat recycling, significantly reduce energy consumption, and ensure the continuous and stable operation of the system.

[0031] The system of this embodiment specifically includes:

[0032] A multi-dimensional ion detection module, which is used to detect the concentration distribution characteristics of target inhibitory ions in raw seawater and generate corresponding coating material selection instructions;

[0033] Specifically, the target inhibitory ions are metal cations that play a dominant role in the salt deposition process, such as Ca 2+ , Mg 2+; The concentration distribution feature is the concentration difference map of ions in the spatial dimension; the coating material selection instruction is the electrode coating material matched according to the ion type, such as selecting a sulfonic acid type ion exchange resin coating for calcium ions. The multi-dimensional ion detection module uses a combination of a spectral analyzer and a conductivity sensor to detect the concentrations of calcium, magnesium and other ions in the raw seawater in real time and generate a three-dimensional distribution map of them at different depths and positions. Through a preset coating adaptation algorithm, the corresponding adsorption coating type is selected according to the ion concentration peak region.

[0034] The electric field dynamic coupling module is used to activate the adsorption coating on the electrode surface according to the coating material selection instruction and adjust the capture termination signal through a dynamic electric field;

[0035] The shock wave generation module is used to start the main pump to generate a fluid shock wave according to the termination signal and apply it to the target area to perform the sediment fragmentation action and screen the particle set that meets the preset particle size grade;

[0036] The precipitation recovery module is used to detect the movement trajectory of the particle set and generate a diversion signal to separate it to an independent recovery path;

[0037] The monitoring module is used to monitor the ion concentration of the finally output softened water and inversely calculate the pollution index on the coating surface;

[0038] The thermal cycle feedback device is used to start the self-cleaning mode according to the pollution index and transfer the waste heat in the cleaning process to the pump set.

[0039] Specifically, this system realizes refined ion capture and sediment treatment through dynamic coupling electric field adsorption and fluid shock wave fragmentation technologies. The multi-dimensional ion detection and dynamic matching of the coating material optimize the adsorption efficiency, and the composite interference field generated by the superposition of the phase difference pressure waves can achieve selective fragmentation for sediments with different hardnesses. The thermal cycle feedback mechanism triggers self-cleaning through the pollution index, reduces energy consumption waste, and uses waste heat to improve the efficiency of the pump set.

[0040] Optionally, as Figure 2 shown, the electric field dynamic coupling module includes:

[0041] The characteristic switching unit is used to generate a matching voltage polarity switching frequency and amplitude according to the coating material selection instruction to obtain voltage parameters;

[0042] Specifically, the characteristic switching unit matches the material type in the coating material selection instruction with the adapted voltage polarity and amplitude range through a preset material-voltage matching database. According to the ion adsorption rate requirement, the switching frequency is dynamically adjusted, and the corresponding voltage parameters are output. The material type can be sulfonic resin or amino polymer. For example, the voltage parameters corresponding to the sulfonic resin coating are +12V / -8V, and the switching frequency is 10Hz; the voltage parameters corresponding to the amino coating are +15V / -5V, and the switching frequency is 15Hz.

[0043] The termination trigger unit is used to trigger the coating to periodically capture ions according to the voltage parameters, and obtain a termination signal when the current efficiency decreases.

[0044] Specifically, the current efficiency is a comprehensive evaluation index of the adsorption efficiency and energy consumption. The termination signal is an instruction signal to stop the adsorption action and start the next process. Periodically capturing ions is an operation to periodically change the electric field direction according to the voltage parameters to enhance the ion migration rate. The termination trigger unit monitors the current efficiency during the coating adsorption process after the electrode is powered on. The current efficiency is defined as the ratio of the amount of adsorbed ions per unit time to the consumed electric energy. For the current efficiency η, there is

[0045]

[0046] In the formula, Q ads is the molar amount of ions adsorbed by the coating, V is the average voltage, I is the average current, and T xf is the adsorption time. When the current efficiency η drops to a preset threshold, such as 65% of the initial value, it is determined that the coating adsorption is saturated, and a termination signal is generated. After the trigger signal, the electric field is turned off and enters the anti-corrosion state.

[0047] Exemplarily, when detecting that the peak concentration of Ca 2 + in seawater is 600mg / L, the sulfonic resin coating is selected; the voltage polarity switching frequency is retrieved from the database as 12Hz, and the amplitude is +10V / -6V; the initial current efficiency η = 0.8mol / kWh, and after running for 40 minutes, the current efficiency drops to 0.52, which is lower than the threshold 0.6, triggering the termination signal; the electric field is turned off, and the shock wave breaking process is started. By dynamically adjusting the voltage polarity switching frequency, the ion adsorption rate is improved, and the coating is prevented from failing due to local overload; based on the termination signal trigger of the current efficiency threshold, the coating saturation point is accurately judged, and the energy consumption of ineffective adsorption is prevented.

[0048] Optionally, as Figure 2 shown, the shock wave generation module includes:

[0049] The shock wave startup unit is used to start the main pump to generate a fluid shock wave according to the termination signal and apply it to the target area;

[0050] Specifically, after receiving the termination signal from the electric field dynamic coupling module, the shock wave startup unit activates the high-pressure main pump and adjusts its output power to a preset value. The main pump adopts variable frequency control technology to automatically match the shock wave frequency according to the thickness of the sediment in the target area, generating an adjustable pulsed jet with a frequency range of 50 - 300 Hz. The fluid shock wave adds radial centrifugal force through a spiral accelerator to form a high-energy focused beam acting on the sediment on the inner wall of the pipeline. Among them, the fluid shock wave is an instantaneous high-pressure wave generated by the sudden change of liquid pressure, the main pump is the core power device for generating high-pressure fluid, the spiral accelerator is a mechanical component that enhances the energy of the fluid shock wave through a vortex structure, and the target area is the part of the pipeline or container where the sediment accumulates.

[0051] The data analysis unit is used to collect the mechanical response data of the fluid shock wave and convert and calculate it into the retention coefficient of the sediment in the pipeline;

[0052] Specifically, the data analysis unit real-time collects the peak pressure and vibration frequency of the shock wave in the pipeline through a pressure sensor and an accelerometer, and combines the pipeline material parameters, such as the elastic modulus of the steel pipe being 200 GPa, to calculate the adhesion strength of the sediment retained on the pipe wall. The retention coefficient K zl is quantified using the following formula:

[0053]

[0054] In the formula, ΔP0 is the initial shock wave pressure difference, ΔP t is the shock wave pressure difference at time t, k0 is the sediment hardness factor, which is obtained through laboratory calibration. For example, for calcium carbonate, it is taken as 0.85. When the retention coefficient is greater than 0.7, it is determined that the sediment is stubbornly retained and needs to be intensively broken.

[0055] Among them, the mechanical response data are physical quantities such as pressure and vibration generated by the shock wave acting on the pipe wall, the retention coefficient is a dimensionless parameter characterizing the adhesion strength of the sediment, and the anti-blocking mapping algorithm is a mathematical model for matching the pipeline stiffness adjustment strategy according to the retention coefficient.

[0056] The shock wave adjustment unit is used to generate a pipeline stiffness adjustment instruction based on the retention coefficient and trigger a phase difference pressure wave output by the dual pipelines;

[0057] Specifically, the shock wave adjustment unit inputs the residence coefficient into the anti-blocking mapping algorithm and outputs the stiffness adjustment thresholds for the main pipeline and the branch pipeline. For example, the stiffness of the main pipeline is increased by 20%, and the stiffness of the branch pipeline is decreased by 15%. The wall thickness or support structure of the pipeline is dynamically adjusted through a hydraulic valve to cause deformation differences in the double pipelines, forming a pressure wave with a phase difference of 90°. For example, the main pipeline outputs a steady pressure wave of 200 Hz, and the branch pipeline superimposes a high-frequency oscillation wave of 250 Hz. After the phase difference interference of the two, a composite wave is generated. Among them, the pipeline stiffness is the ability of the pipeline to resist deformation, the phase difference pressure wave is the superimposed waveform where the wave peaks and troughs output by different pipelines are misaligned, and the stiffness switching threshold is the critical parameter for triggering the pipeline stiffness adjustment.

[0058] The crushing execution unit is used to perform the sediment crushing action through the superposition effect of the phase difference pressure wave and screen the particle set that meets the preset particle size grade.

[0059] Specifically, the crushing execution unit uses the phase difference pressure wave to form an interference field in the pipeline. In the high-intensity shear force area in the interference field, that is, the local stress generated at the wave peak superposition point exceeds the critical compressive strength of the sediment, such as the compressive strength of calcium carbonate is 50 MPa. Sediments with different hardnesses are broken into the preset particle size under differential resonance, and the unqualified particles return to the secondary crushing through the circulation loop. Among them, the composite interference field is the mechanical action area formed by the superposition of multiple pressure waves, the differential resonance is the non-uniform vibration fragmentation phenomenon generated by substances with different hardnesses at specific frequencies, and the preset particle size grade is the target particle size set by screening or centrifugal separation.

[0060] Exemplarily, there is an 8-mm-thick calcium carbonate deposition layer attached to the inner wall of a seawater cooling pipeline, resulting in a 30% decrease in flow rate; after receiving the termination signal, the main pump starts to generate a fluid shock wave of 200 Hz with a peak pressure of 12 MPa; ΔP0 = 12 MPa, ΔP t = 9.6 MPa. After running for 2 minutes, k0 = 0.85, and the residence coefficient is calculated to be 0.17, determining that the pipeline stiffness needs to be adjusted. The stiffness of the main pipeline is increased by 15% to output a wave of 200 Hz; the stiffness of the branch pipeline is decreased by 10% to output a wave of 220 Hz with a phase difference of 60°; the peak pressure of the composite interference field reaches 25 MPa, and the sediment is broken into 0.5-mm particles, and the passing rate after screening is 92%. Through the directional interference focusing of the phase difference pressure wave, high-intensity local crushing is achieved, reducing damage to the pipe wall; the adjustment of the stiffness difference between the double pipelines enhances the waveform superposition effect, significantly improving the sediment screening accuracy and processing efficiency.

[0061] Optionally, the generating a fluid shock wave and applying it to the target area includes:

[0062] When receiving the termination signal, monitoring the ion crystallization morphology on the surface of the coating material;

[0063] Specifically, the surface images of the coating are collected in real time by a high-resolution industrial camera or a scanning electron microscope (SEM), and the microstructure of ion crystallization, such as dendritic crystallization, lamellar crystallization, and needle-like crystallization, is analyzed. According to the classification of the crystallization morphology, for example, using a convolutional neural network algorithm, the corresponding shock wave parameter regulation strategy is matched. For example, dendritic crystallization requires high-frequency shock waves to break, and lamellar crystallization requires high-pressure steady waves to peel off. Among them, the ion crystallization morphology is the microscopic crystal structure formed by the deposition of ions on the coating surface; the scanning electron microscope is an optical device used for nano-scale surface topography observation; the convolutional neural network algorithm is a classification model based on image feature extraction.

[0064] According to the ion crystallization morphology, adjust the output force of the main pump and add a spiral acceleration path;

[0065] Specifically, the adjustment of the output force of the main pump is based on the crystallization hardness matching formula:

[0066]

[0067] In the formula, k1 is the pump force coefficient, which is calibrated through experiments. For example, for a carbon steel pump, it is taken as 1.2, S c is the crystallization hardness parameter, dendritic = 3.0, lamellar = 2.5, needle-like = 4.0, d p is the average particle size of the target deposit. The additional spiral acceleration path uses double spiral guide vanes built into the pipeline to make the fluid rotate and accelerate along the axis, and the shock wave energy focusing rate is increased by 20%-40%. Among them, the output force of the main pump is the fluid pressure generated by the pump body; the spiral acceleration path is a vortex channel that enhances the fluid shock wave energy through mechanical structure design; the pump force coefficient is a correction factor comprehensively affected by material and structure parameters.

[0068] The fluid shock wave formed according to the output force of the main pump.

[0069] Specifically, the adjusted output force of the main pump drives the fluid to form a controllable shock wave. For the peak value P of the shock wave max , there is

[0070]

[0071] In the formula, ρ is the fluid density. For example, for seawater, it is taken as 1025 kg / m 3 , v lt is the fluid flow rate, which can reach 25 m / s after passing through the spiral acceleration path, and ε is the path additional energy gain coefficient. When spirally accelerating, ε = 0.3. The shock wave is applied to the target area through a directional nozzle, and the action time is 0.1 - 0.5 seconds with a cycle interval. Among them, the fluid shock wave is an instantaneous high-energy transfer caused by the sudden change of liquid pressure; the path additional energy gain coefficient is the proportion of the improvement of the fluid kinetic energy by the spiral structure; the directional nozzle is a mechanical component that controls the propagation direction and focusing range of the shock wave.

[0072] Through the real-time monitoring and dynamic regulation mechanism of the ionic crystal form, the precise matching of shock wave parameters is achieved, enhancing the targeting of breaking specific crystal structures. The spiral acceleration path converts the fluid kinetic energy into shock wave focusing energy, reducing ineffective energy consumption; the pump force calculation model based on crystal hardness and particle size ensures that the shock wave intensity can efficiently remove sediments while avoiding damage to pipelines or coatings. This solution significantly improves the processing efficiency and equipment life of the high-pressure soft water system.

[0073] Optionally, the generating of the pipeline stiffness regulation instruction based on the residence coefficient includes:

[0074] Inputting the residence coefficient into the anti-blocking mapping algorithm to output the stiffness switching thresholds of the main pipeline and the branch pipeline;

[0075] Specifically, the anti-blocking mapping algorithm converts the residence coefficient into the stiffness regulation parameters of the double pipelines, namely the main pipeline stiffness S1 and the branch pipeline stiffness S2, through the following formula:

[0076] S1 = S baseline + G1 * (1 - K zl ),

[0077] S2 = S baseline - G2 * K zl ,

[0078] In the formula, S baseline is the original pipeline stiffness. For example, for a steel pipe, it is taken as 200 GN / m 2 , G1 is the main pipeline stiffness regulation gain coefficient, which is an experimentally calibrated value, usually taken as 0.8, and G2 is the branch pipeline stiffness regulation attenuation coefficient, which is an experimentally calibrated value, usually taken as 0.5. When the difference between the main pipeline stiffness S1 and the branch pipeline stiffness S2 output by the algorithm exceeds the preset threshold, such as being greater than 10 GN / m 2 , a stiffness switching threshold instruction is generated. Among them, the anti-blocking mapping algorithm is an optimization algorithm that correlates the residence coefficient with the pipeline stiffness regulation parameters through mathematical modeling; the stiffness switching threshold is a critical difference parameter that triggers the change of the pipeline stiffness; the gain coefficient and the attenuation coefficient are weight factors that adjust the increase and decrease ratios of the pipeline stiffness.

[0079] Using the stiffness switching threshold to trigger the deformation difference of the double pipelines to form a phase difference;

[0080] Specifically, the thickness of the support ring of the main pipeline is adjusted by the hydraulic servo system, such as increasing by 2 mm, and the wall thickness of the branch pipeline is reduced, such as reducing by 1.5 mm, so that the stiffness difference between the two pipelines reaches 15 GN / m 2 . The deformation difference causes different pressure wave propagation speeds. When the two pipelines simultaneously output pressure waves with a frequency of f0, the phase difference calculation formula is:

[0081]

[0082] In the formula, L1 and L2 are the pipeline lengths, and v1 and v2 are the wave velocities. Among them, the deformation difference is the geometric structure change caused by different stiffnesses of the pipeline; the phase difference is the propagation position difference of two waves at the same time point; the hydraulic servo system is an actuator that controls the displacement of mechanical components through liquid pressure.

[0083] Generate a stiffness adjustment command by using the phase difference.

[0084] Specifically, by real-time monitoring the deviation between the phase difference and the target phase difference, generate a feedback control signal to dynamically adjust the stiffness S1 of the main pipeline and the stiffness S2 of the branch pipeline. If the phase difference monitored in real time is less than the target phase difference, further increase the stiffness S1 of the main pipeline or decrease the stiffness S2 of the branch pipeline until the phase difference meets the requirements of the preset interference field. Among them, the stiffness adjustment command is a closed-loop control command for dynamically adjusting the pipeline stiffness according to the phase difference; the target phase difference is a preset angle value for optimizing the pressure wave superposition effect; the closed-loop control is an adaptive mechanism for reversely adjusting the input parameters according to the output result.

[0085] Convert the retention coefficient into a stiffness control command through an intelligent mapping algorithm, and real-time adjust the deformation of the double pipeline to generate an accurate phase difference. The coupling effect of the deformation difference and the pressure wave propagation speed ensures the maximization of the mechanical strength of the interference field, and specifically destroys high-adhesion sediments. The closed-loop feedback mechanism dynamically compensates for environmental interference, ensures the stability of the treatment effect, extends the service life of the pipeline and reduces the maintenance cost.

[0086] Optionally, the execution of the sediment fragmentation action by the superposition effect of the phase difference pressure wave includes:

[0087] According to the phase difference pressure wave, superimpose a high-frequency oscillation wave and a steady-state pressure wave to form a composite interference field;

[0088] Specifically, control the main pump to generate a steady-state pressure wave such as a frequency of 150 Hz and a peak pressure of 8 MPa, and at the same time superimpose a high-frequency oscillation wave such as a frequency of 500 Hz and a peak pressure of 3 MPa through the auxiliary pump. The phase difference between the two waves is set to 90°, and the pressure distribution of the synthesized wave is calculated according to the wave superposition formula. For the amplitude P of the synthesized wave total , there is:

[0089] P total =P steady *sin(2*π*f1*t)+P osc *sin(2*π*f2*t+Δφ),

[0090] In the formula, P steady is the amplitude of the steady-state pressure wave, P oscHere, \(A\) is the amplitude of the high-frequency oscillation wave, \(f_1\) and \(f_2\) are the frequencies of two waves, and \(\Delta\varphi\) is the phase difference. After synthesis, a composite interference field with periodic intensity variation is formed, whose peak pressure reaches 11 MPa and valley pressure is 2 MPa. Among them, the high-frequency oscillation wave is a short-period pressure fluctuation with a frequency higher than 200 Hz; the steady-state pressure wave is a continuous pressure wave with constant frequency and amplitude; the composite interference field is a dynamic mechanical action area formed by the superposition of multiple pressure waves.

[0091] According to the high-intensity shear force area in the composite interference field, differential resonance is generated for sediments with different hardnesses, causing particles of a preset particle size grade to break under critical stress;

[0092] The broken particles are obtained to get a particle set.

[0093] Specifically, the high-intensity shear force area is periodically focused by the peak points of the composite wave, and its instantaneous shear stress \(\tau\) satisfies the critical stress formula:

[0094]

[0095] In the formula, \(\sigma\) c is the compressive strength of the sediment. For example, for calcium carbonate, \(\sigma\) c = 50 MPa, \(r\) d is the dynamic stress enhancement factor. When the high-frequency oscillation wave acts, \(r\) d = 0.3. When \(\tau\geq\sigma\) c , the sediment undergoes shear fracture; sediments with different hardnesses are selectively broken in the interference field due to the difference in resonance frequencies. Among them, differential resonance is a violent response caused by the same frequency of the inherent vibration and external force of a substance at a specific frequency; critical stress is the minimum shear stress value that causes the material to fracture; the dynamic stress enhancement factor is the equivalent weakening coefficient of high-frequency vibration on the compressive strength of the material.

[0096] Specifically, the broken particles are screened by a screening device such as a vibrating screen or a centrifugal separator according to a preset particle size grade such as 0.2 - 1.0 mm. The unqualified particles flow back to the shock wave action area for secondary treatment, and the qualified particles enter the recovery bin through the diversion channel. Among them, the particle set is an aggregate of broken particles that meet the target particle size range; the screening device is a mechanical component that realizes physical separation according to the particle size; the diversion channel is a fluid guiding structure that controls the movement path of the particles.

[0097] By optimizing the superposition mode of the phase difference pressure waves, a high-intensity shear force area is formed in the interference field, and differential stress actions are applied to sediments with different hardnesses. The high-frequency oscillation wave reduces the critical shear strength of the sediment, while the steady-state pressure wave provides the basic breaking energy. The superposition of the two realizes efficient selective crushing. The screening and recycling mechanism ensures that the particle size of the particles meets the standard and reduces material waste. This scheme significantly improves the sediment treatment efficiency and reduces the risk of equipment loss.

[0098] Optionally, detecting the movement trajectory of the particle set and generating a diversion signal for separation into an independent recovery path includes:

[0099] Collecting the movement trajectory differences of the particles in the particle set in the composite interference field to obtain a velocity vector distribution;

[0100] Specifically, in the composite interference field, the particle set is subjected to the dynamic mechanical action of a pressure wave to generate different movement trajectories. The three-dimensional displacement data of the particles are synchronously collected by an array of high-speed cameras and a laser Doppler velocimeter, and the position changes of each particle are recorded at a frequency of 2000 frames per second. The particle tracking algorithm is used to convert the displacement between consecutive frames into an instantaneous velocity vector, and a velocity vector distribution map of each particle is established. This distribution map contains the spatial distribution characteristics of the velocity magnitude and direction, and is used to characterize the dynamic behavior differences of particles with different particle sizes and densities in the interference field.

[0101] Among them, the composite interference field is a periodically fluctuating pressure region formed by the superposition of a high-frequency oscillation wave and a steady-state pressure wave, and the particles are subjected to non-uniform mechanical actions in this region. The array of high-speed cameras is a visual acquisition system composed of multiple synchronously triggered high-speed imaging devices, which is responsible for capturing the trajectories of high-speed moving particles. The laser Doppler velocimeter is an optical instrument that uses the principle of laser interference to measure the velocity of fluids or particles, and can accurately obtain the instantaneous velocity of micron-sized particles. The particle tracking algorithm is a displacement analysis algorithm based on image feature point matching, and the motion vector is calculated by the coordinates of the particles between adjacent frames.

[0102] Matching the velocity vector distribution with the deflection angle threshold of the preset recovery path to obtain an adjustment of the injection frequency of the diversion device and generate a diversion signal.

[0103] Specifically, the deflection angle threshold of the preset recovery path is an angle range calculated based on the physical constraint conditions of the target particle recovery path. For example, when the particles enter the coarse particle recovery bin, they need to deflect by 25° ± 5°, and when they enter the fine particle recovery bin, they need to deflect by 40° ± 5%. By comparing the direction of the particle velocity vector with the theoretical deflection angle of the target path, the real-time angle deviation value is calculated. When the deviation exceeds the threshold, the opening frequency of the piezoelectric injection valve in the diversion device is adjusted according to the deviation ratio. For example, when the deviation increases by 2° each time, the injection frequency is increased by 15 Hz, thereby generating a pulse signal for controlling the diversion direction of the fluid. The injection frequency adjustment instruction is output to the diversion device through a signal converter to drive it to inject air flow or liquid flow to correct the particle movement trajectory.

[0104] Among them, the deflection angle threshold is the allowable deviation range of the particle movement direction required for the separation of the recovery path. The piezoelectric injection valve is an actuator that uses the inverse piezoelectric effect of piezoelectric ceramics to achieve high-frequency fluid injection, and its response frequency can reach more than 500 Hz. The signal converter is an electronic module that converts the control logic signal into a physical drive signal, for example, converts the PWM signal into a voltage drive signal.

[0105] Specifically, the composite interference field is a dynamic action area formed by the superposition of multiple pressure waves. There is a periodically changing pressure gradient inside it, which causes the particles to have a velocity vector differentiation due to the differences in mass and volume. The velocity vector distribution is a set of data maps that describe the velocity magnitude and direction of each particle in the process of particle group movement, and the dispersion characteristics of the particle group can be analyzed by statistical methods. The diversion signal is an instruction signal that controls the action of the diversion device, and changes the particle movement trajectory by adjusting the timing and intensity of fluid injection, so that it deviates from the original path and enters the specified recovery channel.

[0106] Exemplarily, in the reverse osmosis membrane pretreatment link of a seawater desalination plant, the system needs to separate the crushed calcium carbonate particle set with a particle size of 0.3 - 0.8 mm. The diversion paths set in the composite interference field include two independent recovery channels for coarse particles and fine particles. Coarse particles are those larger than 0.6 mm, and fine particles are those less than or equal to 0.6 mm. After the high-speed camera captures the particle movement trajectory, the velocity vector distribution generated by the algorithm shows that the average velocity direction deflection of fine particles is 32°, and that of coarse particles is 18°; the preset deflection angle thresholds are set to 37° for the fine particle path and 22° for the coarse particle path, and the actual angle deviations of the two are 5° and 4° respectively; the diversion controller increases the piezoelectric injection valve frequency from the default 100 Hz to 130 Hz (fine particle path) and 115 Hz (coarse particle path) according to the deviation ratio, enhancing the diversion air curtain intensity; after adjustment, the deflection angle of the fine particle recovery path is corrected to 38°, and the coarse particle path is corrected to 21°, and the particle sorting accuracy is increased to 94%. By dynamically tracking the particle trajectory in the composite interference field and optimizing the diversion parameters in real time, the efficient sorting of particles with different particle sizes is realized, the risk of membrane blockage caused by fine particles straying into the coarse particle channel is reduced, and at the same time, the problem of secondary particle deposition caused by insufficient diversion is reduced, significantly improving the sorting accuracy of the recovery path and the operation stability of the system.

[0107] Optionally, monitoring the ion concentration of the finally output softened water and inversely calculating the pollution index on the coating surface includes:

[0108] Monitoring the concentration of the target inhibitory ions in the finally output softened water to obtain the actual concentration parameter value of the target inhibitory ions;

[0109] Specifically, specifically, the concentration of the target inhibitory ions in the softened water is detected in real time through an ion-selective electrode array, such as calcium ions (Ca 2+ ) and magnesium ions (Mg 2+) The ion-selective electrode array consists of multiple sensitive membranes for different ions. Data is collected every 30 seconds and, after being processed by a signal amplifier and an analog-to-digital converter, the actual concentration parameter value is output. The target inhibitory ion is the dominant salt deposition factor that needs to be adsorbed and removed during the softening process, and the actual concentration parameter value is the real-time detection value of the above-mentioned ion in the softened water body, with the unit of mg / L.

[0110] Among them, the ion-selective electrode array is a sensor group based on the principle of ion-exchange membrane, which can synchronously detect the concentrations of multiple specific ions; the signal amplifier is an electronic module used to enhance weak electrical signals; the analog-to-digital converter is an integrated circuit that converts analog voltage signals into digital values.

[0111] According to the concentration distribution characteristics of the target inhibitory ion in the original seawater, the initial concentration parameter value of the target inhibitory ion is calculated;

[0112] Specifically, before the original seawater enters the system, a multi-channel spectroanalyzer is used for full-spectrum scanning to obtain the absorbance data at different wavelengths. Based on the Beer-Lambert law, an ion concentration-absorbance standard curve is established, and the initial concentration distribution characteristics of the target inhibitory ion are extracted by combining the principal component analysis method. The initial concentration parameter value is the average concentration of the corresponding ion in the original seawater. For example, the comprehensive mean value of multi-dimensional detection data is calculated by the regional weighted algorithm.

[0113] Among them, the multi-channel spectroanalyzer is a detection device that simultaneously covers the visible and ultraviolet spectral bands, and is used to quickly determine the ion species and concentration in the solution; the Beer-Lambert law is a physical law that describes the linear relationship between absorbance and solution concentration; the principal component analysis method is a statistical method that reduces the dimension of multi-dimensional data and extracts the main features.

[0114] Calculate the concentration deviation value between the actual concentration parameter value and the initial concentration parameter value;

[0115] Specifically, the absolute concentration deviation is obtained by subtracting the initial concentration parameter value of the original seawater from the actual concentration parameter value of the softened water body. Further normalization is performed to obtain the concentration deviation value, eliminating the influence of the original concentration base value on the dimension of the calculation result. Among them, the absolute concentration deviation is the direct difference between the actual value and the initial value; the concentration deviation value is the normalized deviation amount expressed as a percentage; normalization is a mathematical method of scaling data to a unified dimension.

[0116] Calculate the fouling index using the concentration deviation value. For the fouling index W Z , there is:

[0117] W Z = Z pc * T yx * D T ,

[0118] In the formula, Z pc is the concentration deviation value, T yx is the running duration, and D T is the temperature correction factor.

[0119] Specifically, the running duration refers to the cumulative working time of the system since the last cleaning, with the unit of hour. The temperature correction factor is determined according to the surface temperature T s of the electrode coating according to the empirical formula D T = 1 + 0.02 * (T s - 25), where 25°C is the reference temperature. The pollution index characterizes the attenuation degree of the coating adsorption performance. When the pollution index exceeds the threshold, such as 500, the cleaning action is triggered. Among them, the temperature correction factor is an adjustment coefficient to compensate for the influence of temperature on the ion adsorption efficiency; the empirical formula is a correction model fitted through experimental data. The pollution index is a comprehensive evaluation index to quantify the deposition degree of pollutants on the coating surface, and it reflects the dynamic process of pollutant accumulation through the product of the concentration deviation, running time, and temperature factors. The temperature correction factor is used to correct the influence of the environmental temperature on the ion migration rate to ensure the accuracy of the index calculation under variable temperature conditions. The running duration measures the continuous adsorption load of the coating from the time dimension, and the concentration deviation value directly reflects the actual decline level of the adsorption efficiency.

[0120] By dynamically quantifying the coating performance attenuation through the pollution index, the cleaning is triggered before the pollutant accumulation causes a significant decline in the adsorption efficiency, avoiding the subsequent processing capacity collapse caused by the coating failure. The introduction of the temperature correction factor improves the sensitivity to abnormal ion adsorption under high-temperature conditions and ensures the reliability of the cleaning mechanism in different environments.

[0121] Optionally, starting the self-cleaning mode according to the pollution index and transferring the waste heat during the cleaning process to the pump group includes:

[0122] When the pollution index is greater than the preset index threshold, start the coating thermal expansion cleaning and generate temperature gradient control parameters according to the pollution index;

[0123] Specifically, by real-time monitoring the pollution index and the preset threshold, when the pollution index is greater than the preset threshold, trigger the thermal expansion cleaning program. The coating thermal expansion cleaning is to apply an alternating current, such as a 0 - 50A pulse, to the electrode surface, and use the Joule effect to make the coating material expand and contract periodically, with the expansion coefficient difference of 0.5×10 -6 / °C, to peel off the surface ion crystals. The temperature gradient control parameters are calculated according to the proportional relationship between the pollution index and the threshold. For the temperature gradient control parameter ΔT td , there is

[0124]

[0125] Wherein, k2 is the correction factor of the thermal conductivity of the coating material. For example, for a carbon-based coating, it is 0.08, which controls the heating rate and the expansion amplitude, W th is the preset threshold of the w pollution index. Among them, thermal expansion cleaning is a physical cleaning method that uses the characteristic of material deformation when heated to peel off the surface attachments; the temperature gradient control parameter is a control index for adjusting the temperature rise rate during the heating process; the alternating current is an electric current signal that periodically changes direction and magnitude.

[0126] Use the temperature gradient control parameter to adjust the pump group speed compensation amount;

[0127] Specifically, the temperature gradient control parameter ΔT td is converted into the pump group speed compensation amount N through the PID controller c . The speed compensation formula is N c = N0 + k3 * ΔT td , where N0 is the reference speed, such as 3000 rpm, and k3 is the compensation coefficient, such as 5 rpm / °C. Dynamically adjust the power of the main pump motor through the frequency converter to make the pump speed increase linearly with ΔT td and enhance the waste heat transfer efficiency.

[0128] Among them, the speed compensation amount is the adjustment amount of the pump group relative to the reference speed; the PID controller is a closed-loop control system based on the proportional-integral-derivative algorithm; the frequency converter is a power conversion device that adjusts the input frequency of the motor to control the speed.

[0129] Convert the speed compensation amount into the efficiency increase ratio of the pump group output power.

[0130] Specifically, according to the relationship curve between the speed compensation amount N c and the pump efficiency, calculate the actual output power gain. For the pump efficiency Y0, there is:

[0131]

[0132] In the formula, N max is the maximum value of the speed compensation amount. The efficiency increase ratio E g is calculated through the formula:

[0133]

[0134] In the formula, P old is the reference output power, P new is the power after compensation. For the power after compensation, there is:

[0135] P new = k4 * ρ * Q l * N c * Y0,

[0136] Where k4 is the power conversion coefficient, such as 0.95, ρ is the fluid density, Q l Where, the efficiency increase ratio is the percentage of increase in the output power of the pump group relative to the benchmark operating conditions; the power gain is the increment of kinetic energy output; and the efficiency relationship curve is the mathematical model of pump speed and efficiency calibrated by experiments.

[0137] The Joule effect is a physical phenomenon in which electrical energy is converted into thermal energy when current passes through a conductor, and is used to generate the temperature change required for thermal expansion of the coating. The reference speed is the preset pump speed when the system is operating normally, and the compensation coefficient reflects the sensitivity of the temperature gradient to the speed adjustment. The waste heat transfer efficiency is the effective utilization ratio of the heat generated during the self-cleaning process that is transferred to the pump through the heat exchange device.

[0138] For example, a coastal thermal power plant uses seawater as a cooling medium, but due to the Ca 2+ Mg 2+ The concentration was too high, with the initial concentrations of 400 mg / L and 200 mg / L, respectively, resulting in serious scaling of the inner wall of the cooling pipe, which required shutdown and cleaning three times a month on average. In order to improve the operating efficiency, the power plant introduced the high-pressure soft water medium treatment and supply system of the present invention to soften seawater online and remove pipeline sediments.

[0139] The full spectrum of seawater was scanned by a multi-channel spectrometer to generate Ca 2+ Mg 2+ The three-dimensional concentration distribution of the peak area Ca 2+ =600mg / L, Mg 2+ =280mg / L. According to the concentration distribution characteristics dominated by calcium ions, the sulfonic acid resin coating is selected, and the coating material selection instruction is generated. The matching voltage parameters are +10V / -6V and the switching frequency is 12Hz. The sulfonic acid resin coating electrode is activated and the voltage polarity is periodically switched to adsorb Ca 2+ After 40 minutes of operation, the current efficiency dropped from 0.8mol / kWh to 0.52, with a threshold of 0.6, which triggered the termination signal. The main pump started to generate a 200Hz fluid shock wave with a peak pressure of 12MPa, acting on the 8mm thick calcium carbonate deposition layer on the inner wall of the pipeline.

[0140] According to the retention factor K zl =0.85, adjust the main pipeline stiffness to increase by 15%, reduce the branch pipeline stiffness by 10%, output a composite pressure wave with a phase difference of 60°, and a peak pressure of 25MPa. The particle size after crushing is 0.5mm, and is sorted into coarse particles (>0.6mm) and fine particles (≤0.6mm) recovery bins by the diversion device, with a sorting accuracy of 92%.

[0141] Softened water detection Ca 2+The concentration is 85 mg / L, the running time is 72 h, the surface temperature of the electrode is 30 °C, the calculated fouling index is 6233, and the set threshold is 5000. As Figure 3 shown in the fouling index change curve, self-cleaning is thus triggered. An alternating current of 30 A is applied to raise the coating temperature to 75 °C to peel off the surface crystals. The waste heat is transferred to the pump unit through the heat exchanger, the pump speed is increased from 3000 rpm to 3125 rpm, and the output power gain is 22.7%.

[0142] In this embodiment, by deploying a high-pressure soft water system in a coastal power plant, full-process automation of ion adsorption, sediment fragmentation, and energy feedback is achieved. The composite interference field directional fragmentation technology significantly reduces the pipeline cleaning frequency. The fouling index model accurately predicts the fouling state of the coating. The thermal expansion cleaning combined with the waste heat feedback mechanism avoids shutdown maintenance, reduces the energy consumption of the pump unit, and extends the equipment life at the same time. This solution provides a sustainable solution for high-salinity water treatment and has industrial promotion value.
