DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. The implementation, functional characteristics and advantages of the present invention will be further described with reference to the embodiments and the accompanying drawings.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Refer to the attached Figure 1 , a method for separating and discharging multiphase fluid in a vacuum water return tank in an embodiment of the present invention, includes: S1: Based on the pre-simulated fluid type, collect the physical properties of the fluid from the vacuum water return tank, wherein the fluid type specifically includes gas, liquid and solid particles, and the physical properties specifically include density, viscosity, surface tension and particle size distribution; S2: Judge whether the fluid concentration of the fluid exceeds a preset threshold; S3: If so, identify the stratification phenomenon of the fluid, and according to the stratification phenomenon, use a preset detection device to measure the phase ratio distribution of the fluid, and obtain the change of the fluid properties of the fluid in the vacuum water return tank, wherein the stratification phenomenon specifically includes bubble floating, solid particle sedimentation and clear liquid-gas layer; S4: Judge whether the change of the fluid properties reaches a preset condition; S5: If the condition is met, dynamically adjust the pressure of the vacuum water return tank according to the type of the fluid, apply an electric field to the fluid through a preset electro-ionization device, induce bubble aggregation in the liquid of the fluid, perform directional offset on the charged particles in the liquid, and adaptively adjust the electric field parameters of the electric field based on the physical properties, where the electric field parameters specifically include voltage frequency, electric field action time, and electric field action direction.

[0019] In this embodiment, the system collects the physical properties of these fluids from the vacuum return water tank based on the fluid types obtained in advance simulation, and the fluid types specifically include gas, liquid and solid particles. The physical properties specifically include density, viscosity, surface tension and particle size distribution, and then the system determines whether the fluid concentration of these fluids exceeds the preset threshold value to execute the corresponding steps; for example, when the system determines that the fluid concentration of these fluids does not exceed the preset threshold value, the system will consider that the fluid concentration is within a safe range, and the system does not need to perform complex adjustments or separation operations, and can continue to operate in a normal working state, avoiding unnecessary energy consumption and equipment wear. The system will continue to maintain a regular monitoring state and regularly check the flow of the fluid. Speed, pressure, temperature and other parameters to ensure that they are within a reasonable range. At the same time, if the fluid concentration does not exceed the standard, the real-time monitoring frequency of the fluid can be appropriately reduced to avoid over-adjustment, reduce the burden on the sensor, maintain efficient operation, and allow the separation system (such as the separator of the vacuum return tank, the bubble remover, etc.) to continue to operate with the current settings to ensure that the system can handle potential concentration fluctuations in a timely manner when needed; for example, when the system determines that the fluid concentration of these fluids exceeds the preset threshold, the system will consider that the fluid concentration is in an abnormal range, and the system will identify the stratification phenomenon of these fluids. The stratification phenomenon specifically includes bubble floating, solid particle sedimentation and clear liquid and gas layers. According to different stratification phenomena, the application pre-set The detection equipment measures the phase ratio distribution of these fluids and obtains the changes in the fluid properties of these fluids in the vacuum return tank; the system can accurately determine the uneven distribution in the fluid by real-time monitoring of the stratification phenomenon, and measure the phase ratio of the fluid (the ratio distribution of gas, liquid and solid particles) in real time, so as to accurately grasp the distribution of each phase in the vacuum return tank. In this way, the separation parameters and control strategies can be adjusted according to the real-time state of the fluid, and the changes in the fluid properties of the fluid in the tank can be obtained. The system can better predict the behavior of the fluid under different conditions, and then optimize the separation process, which is helpful to adjust the equipment settings (such as pressure, temperature, flow rate, etc.) to adapt to the changes in fluid properties, and through timely detection and measurement of phase ratios, the system The system can actively adjust working parameters such as pressure and flow rate to reduce equipment load, extend equipment service life, and avoid equipment damage caused by overload; the system then determines whether the changes in these fluid properties meet the pre-set conditions to execute the corresponding steps; for example, when the system determines that the changes in these fluid properties do not meet the pre-set conditions, the system will believe that the fluid in the current vacuum return tank does not need to be separated and discharged, and the fluid is currently in a stable state without any abnormalities. The system will continue to monitor the fluid state to ensure that it can respond in time when the fluid properties suddenly change. At the same time, regular checkpoints are set according to time or fluid state, and the fluid state and equipment working parameters are regularly reviewed to ensure that the fluid is within the normal range;For example, when the system determines that these fluid property changes have reached a preset condition, the system will consider that the fluid in the current vacuum return water tank needs to be separated and discharged. The system will dynamically adjust the pressure of the vacuum return water tank according to the fluid type, apply an electric field to these fluids through a preset electro-ionization device, cause bubble aggregation in the liquid of these fluids, and perform directional offset on the charged particles in the liquid. Based on the physical properties, the electric field parameters of the electric field are adaptively adjusted. The electric field parameters specifically include voltage frequency, electric field action time, and electric field action direction. By applying an electric field, the electro-ionization device can perform directional offset on the bubbles, solid particles, etc. in the liquid, promoting the separation between different phases. Bubble aggregation helps to improve the separation efficiency of gas and liquid, while the directional offset of charged particles can effectively reduce the mutual interference between particles and liquid, thereby accelerating the separation process. At the same time, the separation requirements of different fluid types (such as gas, liquid, solid particles) are different. Dynamically adjusting the electric field parameters (voltage, frequency, action time, direction) based on the physical properties of the fluid (such as viscosity, density, particle distribution, etc.) can ensure the most suitable treatment for each fluid. And by precisely adjusting parameters such as the voltage, frequency, and action time of the electric field, the system can ensure that appropriate energy is applied only when needed, which helps to reduce energy waste and lower the power consumption of the system. Adjusting according to the dynamic changes in the fluid state ensures rapid response when there are changes in fluid concentration, stratification phenomenon, or other properties, avoiding the system from operating under inappropriate conditions, thereby improving the long-term stability and reliability of the system.

[0020] In this embodiment, before step S3 of identifying the stratification phenomenon of the fluid, it further includes: S301: Use a preset sensor to monitor the fluid state of the fluid, where the fluid state specifically includes flow rate, temperature, and pressure; S302: Determine whether there is a preset non-uniform distribution in the fluid; S303: If so, based on the sensor, monitor the vibration mode caused by the fluid, collect the propagation speed and intensity of the influence of the fluid on sound waves, and generate effective information on the internal state of the fluid according to the propagation speed and intensity. The vibration mode is specifically the specific vibration characteristics generated after the movement of bubbles or solid particles, and the effective information specifically includes the dynamic changes of the gas-liquid interface, the change of gas solubility, and the concentration distribution of solid particles.

[0021] In this embodiment, the system monitors the fluid state of the fluid by applying a preset sensor. The fluid state specifically includes flow rate, temperature, and pressure. Then, the system determines whether there is a preset non-uniform distribution in these fluid states to perform corresponding steps. For example, when the system determines that there is no preset non-uniform distribution in the fluid state of the fluid, the system will consider that the distribution and flow state of the current fluid in the vacuum return water tank are uniform, without abnormal accumulation, stratification, or other problems that may cause a decrease in separation efficiency. The system will continue to monitor the state of the fluid in real time, including parameters such as flow rate, temperature, and pressure, to maintain dynamic monitoring of the fluid state, ensuring that once a non-uniform distribution or other abnormal changes occur, it can respond in a timely manner. At the same time, when adjustment is not required, by avoiding unnecessary electric field or pressure adjustment, it helps to reduce energy consumption and maintain the long-term stable operation of the equipment, extending the service life of the equipment. For example, when the system determines that there is a preset non-uniform distribution in the fluid state of the fluid, the system will consider that the distribution and flow state of the current fluid in the vacuum return water tank are non-uniform. The system will monitor the vibration mode caused by these fluids based on the sensor. The vibration mode is specifically the specific vibration characteristics generated after the movement of bubbles or solid particles. The system will collect the propagation speed and intensity of the influence of these fluids on sound waves. According to different propagation speeds and intensities, it will generate effective information on the internal state of the fluid. The effective information specifically includes the dynamic changes of the gas-liquid interface, the change of gas solubility, and the concentration distribution of solid particles. By monitoring the vibration mode and the propagation characteristics of sound waves, the system can identify the movement and distribution of bubbles and solid particles in real time, which are direct reflections of the non-uniform distribution in the fluid. For example, the formation and floating of bubbles will affect the vibration mode, and the movement and accumulation of solid particles will generate different vibration characteristics. In this way, the system can timely identify and confirm the non-uniform distribution of the fluid state, avoid ignoring potential separation problems, and at the same time, through the analysis of the propagation speed and intensity of sound waves, the system can monitor the change of gas solubility and the concentration distribution of solid particles, timely identify whether these changes exceed the set threshold, and then adjust the processing strategy in the separation process to ensure the best separation effect of the fluid. And by monitoring the vibration mode and the propagation characteristics of sound waves of the fluid, the system can more accurately determine when and how to perform fluid separation, avoid unnecessary energy consumption caused by over-regulation, and precise control of the separation process helps to reduce unnecessary power consumption and save energy.

[0022] In this embodiment, before step S5 of measuring the phase ratio distribution of the fluid by applying a preset detection device and obtaining the change in the fluid properties of the fluid in the vacuum return water tank, it further includes: S501: Adopt preset cascade separation to remove large - particle bubbles and small - particle bubbles in the fluid respectively. Dynamically switch the preset separation mode based on the phase - body proportion distribution. Among them, the cascade separation specifically includes a coarse separator and a fine separator, and the separation mode specifically includes gas - liquid separation and solid - liquid separation; S502: Determine whether the separation efficiency of the fluid reaches a preset efficiency threshold; S503: If not, adaptively adjust the separation parameters of the preset separator according to the phase - body proportion distribution, detect the abnormal state of the fluid, and collect the abnormal fluid behavior of the fluid based on the abnormal state. Among them, the separation parameters specifically include gas - liquid separation parameters, solid - liquid separation parameters, and liquid - liquid separation parameters. The abnormal state specifically includes a sharp increase in the concentration of solid particles in the fluid and uneven distribution of bubbles. The abnormal fluid behavior specifically includes abnormal bubble generation, solid - particle accumulation, and phase - state mutation.

[0023] In this embodiment, the system adopts preset cascade separation. The cascade separation specifically includes a coarse separator and a fine separator, which respectively remove large particle bubbles and small particle bubbles in the fluid. Based on the phase ratio distribution, the preset separation mode is dynamically switched. The separation mode specifically includes gas-liquid separation and solid-liquid separation. Then, the system determines whether the separation efficiency of the fluid reaches the preset efficiency threshold to execute corresponding steps. For example, when the system determines that the separation efficiency of the fluid can reach the preset efficiency threshold, the system will consider that the current separation process has achieved an ideal effect, the separation process is successfully completed, and the different phases (gas, liquid, solid particles) of the fluid have been effectively separated. The system will stabilize the flow state of the fluid and stop further separation operations. Over-separation may lead to waste of resources and unnecessary load on the system. Therefore, the system will maintain the current separation state, avoid repeated and unnecessary operations, and still need to continuously monitor the fluid state to ensure that no new abnormal phenomena occur. For example, continue to monitor the flow rate, temperature, pressure, and phase ratio of the fluid to promptly detect possible new problems, immediately adjust the separation mode or operation strategy, and detect the operating state and cleanliness of the separator to ensure the long-term stable operation of the equipment. For some separation equipment with self-cleaning functions, the system can start the self-cleaning program to reduce fouling or other factors affecting efficiency. For example, when the system determines that the separation efficiency of the fluid does not reach the preset efficiency threshold, the system will consider that the current separation process is not ideal. The system will adaptively adjust the separation parameters of the separator according to the phase ratio distribution. The separation parameters specifically include gas-liquid separation parameters, solid-liquid separation parameters, and liquid-liquid separation parameters. Detect the abnormal state of the fluid. The abnormal state specifically includes a sharp increase in the concentration of solid particles in the fluid and uneven distribution of bubbles. Based on these abnormal states, collect the abnormal fluid behavior of the fluid. The abnormal fluid behavior specifically includes abnormal bubble generation, solid particle accumulation, and phase state mutation.By adaptively adjusting the separation parameters of the separator according to the phase proportion distribution, the system can respond to the changes in the fluid in real time, which helps to improve the separation efficiency and ensure the effective separation of different phases (gas, liquid, solid particles) in the fluid, so as to meet the quality and operation requirements. Whether it is gas-liquid separation, solid-liquid separation or liquid-liquid separation, dynamic adjustment for different fluid types can maximize the separation effect. At the same time, by monitoring the fluid state and adjusting the separation parameters in real time, it can react in time when the fluid properties change. Whether it is uneven distribution of bubbles, increased concentration of solid particles, or sudden change of phase state, it can quickly identify and adjust the separation strategy. This flexibility and responsiveness can effectively ensure the continuity and stability of the separation process. And by collecting abnormal behaviors of the fluid (such as abnormal bubble generation, particle accumulation, phase state mutation, etc.), the system can accurately identify the problem source and take targeted measures to deal with it. For example, when bubbles or solid particles are abnormal, the system can adjust the separation mode or parameters of the separator to reduce the impact of these abnormal fluid behaviors on the separation efficiency, so as to ensure the consistency and stability of the separation effect.

[0024] In this embodiment, in step S5 of dynamically adjusting the pressure of the vacuum return water tank according to the fluid type, it further includes: S51: Detect the change in the flow rate of the fluid based on the change in the pressure of the vacuum return water tank; S52: Determine whether the pressure change can match the flow rate change; S53: If not, then according to a preset time period, monitor the dynamic changes of the fluid in real time, adaptively adjust the pressure to compensate for the flow rate change based on the dynamic changes, collect the temperature change of the vacuum return water tank, and control the dissolution equilibrium state of the fluid through the temperature change, where the dynamic changes specifically include bubble volume change, flow rate change and fluid flow direction change.

[0025] In this embodiment, the system detects the change in the flow rate of the fluid based on the pressure change of the vacuum water return tank, and then the system determines whether the pressure change can match the flow rate change to execute corresponding steps. For example, when the system determines that the pressure change of the vacuum water return tank can match the flow rate change of the fluid, the system will consider that the flow state of the fluid is stable, and the control and regulation of the fluid by the system are effective. The system will maintain the current output state of the fluid, continue to execute subsequent steps such as fluid treatment, separation, or recovery, without excessive adjustment, avoiding wasting resources, ensuring the stable output of the fluid, and not changing the properties or efficiency of the fluid due to excessive intervention. At the same time, by real-time monitoring and recording data such as flow rate and pressure, the system can evaluate the current operating efficiency, ensure that the fluid treatment or separation process reaches the best effect, and continue to execute subsequent operations, such as fluid separation, heating, cooling, or other necessary treatment steps. The stable flow state can ensure that the subsequent treatment process will not be affected by the flow rate or pressure fluctuations, thereby improving the overall treatment efficiency and effect. For example, when the system determines that the pressure change of the vacuum water return tank cannot match the flow rate change of the fluid, at this time, the system will consider that the flow state of the fluid is unstable. The system will real-time monitor the dynamic changes of the fluid according to the preset time period. The dynamic changes specifically include the change in bubble volume, the change in flow rate, and the change in fluid flow direction. Based on these dynamic changes, the pressure is adaptively adjusted to compensate for different flow rate changes, and the temperature change of the vacuum water return tank is collected to control the dissolution equilibrium state of the fluid through the temperature change. By real-time monitoring the dynamic changes of the fluid (such as bubble volume, flow rate, flow direction), the system can timely and adaptively adjust the pressure to compensate for the change in flow rate, which can avoid the disconnection between pressure and flow rate, ensure the uniformity of fluid flow inside the system, reduce the impact of unstable factors on the equipment and the entire system, improve the system stability. At the same time, by dynamically monitoring the change in flow rate and adaptively adjusting the pressure, ensure that the flow rate is within a reasonable range, avoid too high or too low flow rate affecting the subsequent treatment process. For example, too fast flow rate may cause the particles in the fluid to be unable to be effectively separated, while too slow flow rate may lead to low treatment efficiency. Maintaining an appropriate flow rate helps to improve the overall treatment efficiency. And by monitoring the temperature change and controlling the dissolution equilibrium state of the fluid, the system can accurately adjust the temperature conditions to ensure that the solubility of the gas in the liquid is in an ideal state. The control of temperature helps the dissolution and release of gas and solid particles, promoting the stable distribution and treatment effect of the fluid.

[0026] In step S2 of determining whether the fluid concentration of the fluid exceeds a preset threshold in this embodiment, it further includes: S21: Based on the fluid substance pre-collected in the vacuum water return tank, identify the substance property of the fluid substance, where the substance property specifically includes grease, organic matter, and bubbles; S22: Determine whether the fluid substance exceeds the preset phase concentration change; S23: If so, collect the phase concentration distribution of the fluid from the vacuum return water tank, obtain the concentration exceeding standard area in the vacuum return water tank according to the phase concentration distribution, and perform concentration stratification on the vacuum return water tank based on the concentration exceeding standard area, where the phase concentration distribution specifically includes a gas phase, a liquid phase, and a solid phase.

[0027] In this embodiment, the system identifies the physical properties of the fluid substances pre-collected in the vacuum return water tank. The physical properties specifically include grease, organic matter, and bubbles. Then, the system determines whether these fluid substances exceed the preset phase concentration change to perform corresponding steps. For example, when the system determines that the fluid substances do not exceed the preset phase concentration change, the system will consider the current fluid state to be within the normal range, and the physical proportion and concentration change of the fluid do not reach the critical point that requires intervention. The system will continue to monitor the fluid state to ensure that any changes can be captured in a timely manner. At this time, regular data collection and status monitoring will continue to prevent potential changes from affecting the operation of the system. At the same time, regular analysis and monitoring of the fluid substances will be carried out, and the monitoring parameters include the concentration changes of grease, organic matter, and bubbles, as well as other possible physical parameters (such as temperature, pressure, flow rate, etc.). Through continuous data collection, the system can capture any abnormal changes in a timely manner, so as to take necessary measures before the concentration of the fluid substances exceeds the standard, and dynamically optimize other relevant operating parameters (such as fluid temperature, pressure, or flow rate) according to the current concentration of the fluid substances. Although these adjustments do not necessarily mean that the fluid has become abnormal, they help to further improve the overall operating efficiency and maintain the stable operation of the system. For example, when the system determines that the fluid substances exceed the preset phase concentration change, the system will consider the current fluid state to be abnormal. The system will collect the phase concentration distribution of the fluid from the vacuum return water tank. The phase concentration distribution specifically includes the gas phase, liquid phase, and solid phase. According to the different phase concentration distributions, the concentration exceeding standard areas in the vacuum return water tank will be obtained, and the vacuum return water tank will be stratified according to these concentration exceeding standard areas. By monitoring the phase concentration distributions of the gas phase, liquid phase, and solid phase, the system can accurately identify the specific areas where the concentration exceeds the standard, which can help to determine which areas of the fluid state are abnormal, especially the concentration fluctuation conditions in different areas of the vacuum return water tank. At the same time, when the concentration exceeding standard areas are identified, the system can focus on processing these areas. The system can adaptively adjust the operation mode of the separator according to the fluid characteristics of different areas according to the concentration stratification. For example, the exceeding standard gas area can be separated by gas-liquid separation, and the exceeding standard solid particle area can be separated by solid-liquid separation to more efficiently process different phases. And by locally processing the concentration exceeding standard areas, the system can effectively reduce the overall load of the equipment, avoid over-processing the normal fluid in other areas, reduce equipment wear, and extend the equipment life. A stable fluid processing process can enable the system to continuously operate in the best state.

[0028] In this embodiment, in step S4 of determining whether the change in the physical properties of the fluid reaches the preset condition, it further includes: S41: Based on the working equipment of the vacuum return water tank, identify the operating state of the working equipment, where the working equipment specifically includes pumps, valve drives, and agitators; S42: Determine whether the operating state is affected by the change in the fluid properties; S43: If so, generate the type of impact on the working device according to the change in the fluid properties, and detect the operating indicators of the working device based on the type of impact. The type of impact specifically includes an increase in equipment load, an increase in power consumption, and an increase in pipeline pressure loss. The operating indicators specifically include power consumption indicators, operating environment indicators, and chemical reaction indicators.

[0029] In this embodiment, the system is based on the working equipment of the vacuum water return tank. The working equipment specifically includes pumps, valve drives, and agitators. The system identifies the operating states of these working equipment, and then determines whether the operating states are affected by changes in fluid properties to perform corresponding steps. For example, when the system determines that the operating states of the working equipment are not affected by changes in fluid properties, the system will consider that the current fluid properties are within an acceptable range, and the working equipment is operating normally without being disturbed by abnormal fluid behaviors (such as viscosity changes, bubble generation, etc.). The system will continue to maintain the current operation settings, continue to monitor the states of the fluid and the working equipment to ensure that the equipment operates in a stable state. In the case of insignificant changes in fluid properties, over-adjusting operation parameters is avoided, while unnecessary energy consumption and material usage are reduced. For example, adjusting the rotation speed of the agitator, reducing the power output of the pump, and avoiding unnecessary equipment operation, thereby saving energy and material consumption. And by confirming that the fluid properties have no impact on the equipment operation, the stability of the system can be further verified, and the fault tolerance ability of the system to abnormal fluctuations can be improved. When the fluid properties change, the system can respond and adjust more quickly. For example, when the system determines that the operating states of the working equipment are affected by changes in fluid properties, at this time the system will consider that the current fluid properties are unacceptable and the working equipment is prone to abnormalities. The system will generate the influence types of the working equipment according to the changes in fluid properties. The influence types specifically include increased equipment load, increased power consumption, and increased pipeline pressure loss. According to different influence types, the operating indicators of the working equipment are detected. The operating indicators specifically include power consumption indicators, operating environment indicators, and chemical reaction indicators. By detecting the power consumption, operating environment, and chemical reaction indicators, the system can timely discover abnormal situations such as increased equipment load and increased power consumption caused by changes in fluid properties, so as to give early warnings and avoid equipment failures due to overload or overloading operation. At the same time, according to the influence types generated by the system, the system can dynamically adjust the parameters of the working equipment according to the actual operating state to ensure that the equipment can still operate efficiently and stably under changes in fluid properties. For example, adjusting the power of the pump, changing the pipeline pressure, or adjusting the opening of the valve, etc., to avoid the negative impacts brought by changes in fluid properties. And by monitoring the pipeline pressure loss, the system can optimize the flow state of the fluid in the pipeline, reduce the pressure drop caused by changes in fluid properties, and thus reduce energy consumption and energy waste caused by high-pressure losses. And according to the change in power consumption, the equipment operation mode is adjusted to avoid unnecessary energy consumption waste. For example, when the power consumption exceeds the standard, the system may achieve energy conservation by reducing the equipment load or optimizing the working conditions.

[0030] In this embodiment, in step S1 of collecting the physical properties of the fluid from the vacuum water return tank based on the pre-simulated fluid type, it further includes: S11: Based on the preset fluid collection points in the vacuum water return tank, obtain the fluid change rate of the fluid; S12: Determine whether the fluid change rate matches a preset acquisition frequency; S13: If not, perform multiple samplings at the fluid acquisition point, collect the fluid property differences of the fluid, and generate the distribution and flow trend of the fluid in the vacuum water return tank according to the fluid property differences, where the fluid property differences specifically include temperature differences, pressure differences, flow velocity differences, and bubble gas content differences.

[0031] In this embodiment, the system obtains the fluid change rate of the fluid based on the preset fluid acquisition points in the vacuum water return tank, and then the system determines whether the fluid change rate matches the preset acquisition frequency to execute corresponding steps; for example, when the system determines that the fluid change rate of the fluid can match the preset acquisition frequency, the system will consider that the fluid data can be acquired and monitored at an appropriate frequency, which means that the system can accurately and timely record the state changes of the fluid, ensuring the effectiveness and real-time nature of the data. The system will continue to stably acquire fluid data at the set frequency, ensuring the timeliness and accuracy of the data. At the same time, the matching fluid change rate and acquisition frequency ensure that the system can continuously and stably monitor the state of the fluid, so that the system can continuously track the changes of the fluid, not miss key data points, and when the fluid change rate and acquisition frequency match, the system avoids meaningless excessive data acquisition, thereby avoiding excessive occupation of computing and storage resources and ensuring the efficient operation of the system; for example, when the system determines that the fluid change rate of the fluid cannot match the preset acquisition frequency, at this time, the system will consider that the fluid data cannot be acquired and monitored at an appropriate frequency, and the system will perform multiple samplings at the fluid acquisition point, collect the fluid property differences of these fluids. The fluid property differences specifically include temperature differences, pressure differences, flow velocity differences, and bubble gas content differences. According to different fluid property differences, generate the distribution and flow trend of the fluid in the vacuum water return tank; through multiple samplings, the system can capture the changes in fluid properties at different time points and positions, ensuring a more comprehensive understanding of the behavior and changes of the fluid. Especially when the fluid change rate is large, this method can make up for the deficiency that a single sampling cannot fully cover the fluid state. At the same time, the collection of fluid property differences (such as temperature, pressure, flow velocity, bubble gas content, etc.) can help the system identify the distribution trend of the fluid in the vacuum water return tank, capture different levels and dynamic changes of the fluid, and through multiple samplings of fluid properties at different positions and time points, the system can discover potential non-uniform distribution problems. For example, problems such as uneven bubble distribution and large flow velocity differences can be effectively identified by this method, and the system can take corresponding optimization measures (such as adjusting pressure, operating the stirrer, etc.) accordingly to improve the distribution and flow state of the fluid.

[0032] Refer to the appendix Figure 2, which is a separation and discharge system for multiphase fluids in a vacuum return water tank in an embodiment of the present invention, includes: The acquisition module 10 is configured to collect the physical properties of the fluid from the vacuum return water tank based on the pre-simulated fluid type. The fluid type specifically includes gas, liquid, and solid particles, and the physical properties specifically include density, viscosity, surface tension, and particle size distribution; The judgment module 20 is configured to judge whether the fluid concentration of the fluid exceeds a preset threshold; The execution module 30 is configured to, if so, identify the stratification phenomenon of the fluid, and according to the stratification phenomenon, use a preset detection device to measure the phase ratio distribution of the fluid, and obtain the change in the fluid properties of the fluid in the vacuum return water tank. The stratification phenomenon specifically includes bubble floating, solid particle sedimentation, and clear liquid-gas layer; The second judgment module 40 is configured to judge whether the change in the fluid properties reaches a preset condition; The second execution module 50 is configured to, if it reaches, dynamically adjust the pressure of the vacuum return water tank according to the fluid type, apply an electric field to the fluid through a preset electric field ionization device, cause bubble aggregation in the liquid of the fluid, perform directional deviation on the charged particles in the liquid, and adaptively adjust the electric field parameters of the electric field based on the physical properties. The electric field parameters specifically include voltage frequency, electric field action time, and electric field action direction.

[0033] In this embodiment, the acquisition module 10 collects the physical properties of these fluids from the vacuum return water tank based on the fluid types obtained through pre-simulation. The fluid types specifically include gas, liquid, and solid particles. The physical properties specifically include density, viscosity, surface tension, and particle size distribution. Then, the judgment module 20 determines whether the fluid concentration of these fluids exceeds a pre-set threshold to execute corresponding steps. For example, when the system determines that the fluid concentration of these fluids does not exceed the pre-set threshold, the system will consider that the fluid concentration is within the safe range, and the system does not need to perform complex adjustment or separation operations and can continue to operate in a normal working state, avoiding unnecessary energy consumption and equipment wear. The system will continue to maintain a regular monitoring state, regularly check parameters such as the flow rate, pressure, and temperature of the fluid to ensure they are within a reasonable range. At the same time, when the fluid concentration does not exceed the standard, the real-time monitoring frequency of the fluid can be appropriately reduced to avoid over-regulation, reduce the burden on the sensors, maintain efficient operation, and let the separation system (such as the separator and bubble remover of the vacuum return water tank) continue to operate with the current settings to ensure that the system can handle potential concentration fluctuations in a timely manner when needed. For example, when the system determines that the fluid concentration of these fluids exceeds the pre-set threshold, the execution module 30 will consider that the fluid concentration is in an abnormal range. The system will identify the stratification phenomenon of these fluids. The stratification phenomenon specifically includes bubble floating, solid particle sedimentation, and distinct liquid-gas layers. According to different stratification phenomena, the pre-set detection equipment is used to measure the phase ratio distribution of these fluids to obtain the changes in the fluid properties of these fluids in the vacuum return water tank. By continuously monitoring the stratification phenomenon, the system can accurately determine the non-uniform distribution in the fluid, measure the phase ratio of the fluid in real time (the ratio distribution of gas, liquid, and solid particles), and can accurately grasp the distribution of each phase in the vacuum return water tank. In this way, according to the real-time state of the fluid, the separation parameters and control strategies can be adjusted, and at the same time, by obtaining the changes in the fluid properties in the tank, the system can better predict the behavior of the fluid under different conditions, thereby optimizing the separation process, helping to adjust the equipment settings (such as pressure, temperature, flow rate, etc.) to adapt to the changes in the fluid properties, and by timely detecting and measuring the phase ratio, the system can actively adjust working parameters such as pressure and flow rate, thereby reducing the equipment load, extending the service life of the equipment, and avoiding equipment damage caused by overload. Then, the second judgment module 40 determines whether these changes in fluid properties reach the pre-set conditions to execute corresponding steps. For example, when the system determines that these changes in fluid properties do not reach the pre-set conditions, the system will consider that the fluid in the current vacuum return water tank does not need to be separated and discharged, the fluid is currently in a stable state, and no abnormal phenomenon occurs. The system will continuously monitor the fluid state to ensure that it can respond in a timely manner when the fluid properties change suddenly. At the same time, regular checkpoints are set according to time or fluid state, and the fluid state and equipment working parameters are regularly reviewed to ensure that the fluid is within the normal range.For example, when the system determines that these fluid property changes have reached a preset condition, at this time, the second execution module 50 will consider that the fluid in the current vacuum return water tank needs to be separated and discharged. The system will dynamically adjust the pressure of the vacuum return water tank according to the fluid type, apply an electric field to these fluids through a pre-set electric field ionization device, cause bubble aggregation in the liquid of these fluids, and perform directional displacement on the charged particles in the liquid. Based on the physical properties, the electric field parameters of the electric field are adaptively adjusted. The electric field parameters specifically include voltage frequency, electric field action time, and electric field action direction. By applying an electric field, the electric field ionization device can perform directional displacement on the bubbles, solid particles, etc. in the liquid, promote the separation between different phases. Bubble aggregation helps to improve the separation efficiency of gas and liquid, while the directional displacement of charged particles can effectively reduce the mutual interference between particles and liquid, thereby accelerating the separation process. At the same time, the separation requirements of different fluid types (such as gas, liquid, solid particles) are different. Dynamically adjusting the electric field parameters (voltage, frequency, action time, direction) based on the physical properties of the fluid (such as viscosity, density, particle distribution, etc.) can ensure the most suitable treatment for each fluid. And by precisely adjusting parameters such as the voltage, frequency, and action time of the electric field, the system can ensure that appropriate energy is applied only when needed, which helps to reduce energy waste and lower the power consumption of the system. Adjusting according to the dynamic changes of the fluid state can ensure a quick response when there are changes in fluid concentration, stratification phenomenon, or other properties, avoid the system running under inappropriate conditions, and thus improve the long-term stability and reliability of the system.

[0034] In this embodiment, it further includes: A monitoring module, configured to monitor the fluid state of the fluid by using a preset sensor, where the fluid state specifically includes flow rate, temperature, and pressure; A third judgment module, configured to judge whether there is a preset non-uniform distribution in the fluid; A third execution module, configured to, if so, based on the sensor, monitor the vibration mode caused by the fluid, collect the propagation speed and intensity of the influence of the fluid on sound waves, and generate effective information on the internal state of the fluid according to the propagation speed and intensity, where the vibration mode is specifically the specific vibration characteristics generated after the movement of bubbles or solid particles, and the effective information specifically includes the dynamic changes of the gas-liquid interface, the change of gas solubility, and the concentration distribution of solid particles.

[0035] In this embodiment, the system monitors the fluid state of the fluid by applying a preset sensor. The fluid state specifically includes flow rate, temperature, and pressure. Then, the system determines whether there is a preset non-uniform distribution in these fluid states to perform corresponding steps. For example, when the system determines that there is no preset non-uniform distribution in the fluid state of the fluid, the system will consider that the distribution and flow state of the current fluid in the vacuum water return tank are uniform, without abnormal accumulation, stratification, or other problems that may cause a decrease in separation efficiency. The system will continue to monitor the state of the fluid in real time, including parameters such as flow rate, temperature, and pressure, maintaining dynamic monitoring of the fluid state to ensure that once a non-uniform distribution or other abnormal changes occur, it can respond in a timely manner. At the same time, when no adjustment is required, by avoiding unnecessary electric field or pressure adjustments, it helps to reduce energy consumption and maintain the long-term stable operation of the equipment, extending the service life of the equipment. For example, when the system determines that there is a preset non-uniform distribution in the fluid state of the fluid, at this time, the system will consider that the distribution and flow state of the current fluid in the vacuum water return tank are non-uniform. The system will monitor the vibration mode caused by these fluids based on the sensor. The vibration mode is specifically the specific vibration characteristics generated after the movement of bubbles or solid particles. The system will collect the propagation speed and intensity of the influence of these fluids on sound waves. According to different propagation speeds and intensities, effective information on the internal state of the fluid will be generated. The effective information specifically includes the dynamic changes of the gas-liquid interface, the change of gas solubility, and the concentration distribution of solid particles. By monitoring the vibration mode and the propagation characteristics of sound waves, the system can identify the movement and distribution of bubbles and solid particles in real time, which are direct reflections of the non-uniform distribution in the fluid. For example, the formation and floating of bubbles will affect the vibration mode, and the movement and accumulation of solid particles will produce different vibration characteristics. In this way, the system can identify and confirm the non-uniform distribution of the fluid state in a timely manner, avoiding ignoring potential separation problems. At the same time, by analyzing the propagation speed and intensity of sound waves, the system can monitor the change of gas solubility and the concentration distribution of solid particles, and timely identify whether these changes exceed the set threshold, and then adjust the processing strategy in the separation process to ensure the best separation effect of the fluid. And by monitoring the vibration mode and the propagation characteristics of sound waves of the fluid, the system can more accurately determine when and how to separate the fluid, avoiding unnecessary energy consumption caused by over-regulation. Precise control of the separation process helps to reduce unnecessary power consumption and save energy.

[0036] In this embodiment, it further includes: A removal module, which is used to respectively remove large particle bubbles and small particle bubbles of the fluid by using preset cascade separation, and dynamically switch the preset separation mode based on the phase ratio distribution. Wherein, the cascade separation specifically includes a coarse separator and a fine separator, and the separation mode specifically includes gas-liquid separation and solid-liquid separation; The fourth judgment module is used to judge whether the separation efficiency of the fluid reaches a preset efficiency threshold; The fourth execution module is used to, if not, adaptively adjust the separation parameters of a preset separator according to the phase body proportion distribution, detect the abnormal state of the fluid, and collect the abnormal fluid behavior of the fluid according to the abnormal state, wherein the separation parameters specifically include gas-liquid separation parameters, solid-liquid separation parameters and liquid-liquid separation parameters, the abnormal state specifically includes a sharp increase in the concentration of solid particles in the fluid and uneven distribution of bubbles, and the abnormal fluid behavior specifically includes abnormal bubble generation, solid particle accumulation and phase state mutation.

[0037] In this embodiment, the system adopts a preset cascade separation. The cascade separation specifically includes a coarse separator and a fine separator, which respectively remove large particle bubbles and small particle bubbles in the fluid. Based on the phase ratio distribution, the system dynamically switches between preset separation modes. The separation modes specifically include gas-liquid separation and solid-liquid separation. Then, the system determines whether the separation efficiency of the fluid reaches a preset efficiency threshold to execute corresponding steps. For example, when the system determines that the separation efficiency of the fluid can reach the preset efficiency threshold, the system will consider that the current separation process has achieved an ideal effect, the separation process is successfully completed, and the different phases (gas, liquid, solid particles) of the fluid have been effectively separated. The system will stabilize the flow state of the fluid and stop further separation operations. Over-separation may lead to waste of resources and unnecessary load on the system. Therefore, the system will maintain the current separation state, avoid repeated and unnecessary operations, and still need to continuously monitor the fluid state to ensure that no new abnormal phenomena occur. For example, continue to monitor the flow rate, temperature, pressure, and phase ratio of the fluid to promptly detect possible new problems and immediately adjust the separation mode or operation strategy. Also, detect the operating state and cleanliness of the separator to ensure the long-term stable operation of the equipment. For some separation equipment with self-cleaning functions, the system can start the self-cleaning program to reduce fouling or other factors affecting efficiency. For example, when the system determines that the separation efficiency of the fluid does not reach the preset efficiency threshold, the system will consider that the current separation process is not ideal. The system will adaptively adjust the separation parameters of the separator according to the phase ratio distribution. The separation parameters specifically include gas-liquid separation parameters, solid-liquid separation parameters, and liquid-liquid separation parameters. Detect the abnormal state of the fluid. The abnormal state specifically includes a sharp increase in the concentration of solid particles in the fluid and uneven distribution of bubbles. Based on these abnormal states, collect the abnormal fluid behavior of the fluid. The abnormal fluid behavior specifically includes abnormal bubble generation, solid particle accumulation, and phase state mutation.By adaptively adjusting the separation parameters of the separator according to the phase proportion distribution, the system can respond to the changes in the fluid in real time, which helps to improve the separation efficiency and ensure the effective separation of different phases (gas, liquid, solid particles) in the fluid, so as to meet the quality and operation requirements. Whether it is gas-liquid separation, solid-liquid separation or liquid-liquid separation, dynamic adjustment for different fluid types can maximize the separation effect. At the same time, by monitoring the fluid state and adjusting the separation parameters in real time, it can react in a timely manner when the fluid properties change. Whether it is uneven distribution of bubbles, increased concentration of solid particles, or sudden change of phase state, it can quickly identify and adjust the separation strategy. This flexibility and responsiveness can effectively ensure the continuity and stability of the separation process. And by collecting the abnormal behaviors of the fluid (such as abnormal bubble generation, particle accumulation, phase state mutation, etc.), the system can accurately identify the problem source and take targeted measures to deal with it. For example, when bubbles or solid particles are abnormal, the system can adjust the separation mode or parameters of the separator to reduce the impact of these abnormal fluid behaviors on the separation efficiency, so as to ensure the consistency and stability of the separation effect.

[0038] In this embodiment, the second execution module further includes: A detection unit for detecting the change in the flow rate of the fluid based on the pressure change of the vacuum water return tank; A judgment unit for judging whether the pressure change can match the flow rate change; An execution unit for, if not, monitoring the dynamic changes of the fluid in real time according to a preset time period, adaptively adjusting the pressure to compensate for the flow rate change based on the dynamic changes, collecting the temperature change of the vacuum water return tank, and controlling the dissolution equilibrium state of the fluid through the temperature change, where the dynamic changes specifically include bubble volume change, flow rate change and fluid flow direction change.

[0039] In this embodiment, the system detects the change in the flow rate of the fluid based on the pressure change of the vacuum return water tank, and then the system determines whether the pressure change can match the flow rate change to execute corresponding steps; for example, when the system determines that the pressure change of the vacuum return water tank can match the flow rate change of the fluid, the system will consider that the flow state of the fluid is stable, and the control and regulation of the fluid by the system are effective. The system will maintain the current output state of the fluid, continue to execute subsequent steps such as fluid treatment, separation, or recovery, without excessive adjustment, avoid wasting resources, ensure the stable output of the fluid, and will not change the properties or efficiency of the fluid due to excessive intervention. At the same time, by real-time monitoring and recording data such as flow rate and pressure, the system can evaluate the current operating efficiency, ensure that the fluid treatment or separation process reaches the best effect, and continue to execute subsequent operations, such as fluid separation, heating, cooling, or other necessary treatment steps. The stable flow state can ensure that the subsequent treatment process will not be affected by the flow rate or pressure fluctuations, thereby improving the overall treatment efficiency and effect; for example, when the system determines that the pressure change of the vacuum return water tank cannot match the flow rate change of the fluid, at this time, the system will consider that the flow state of the fluid is unstable. The system will real-time monitor the dynamic changes of the fluid according to the preset time period. The dynamic changes specifically include the change in the volume of bubbles, the change in the flow rate, and the change in the flow direction of the fluid. Based on these dynamic changes, the pressure is adaptively adjusted to compensate for different flow rate changes, and the temperature change of the vacuum return water tank is collected, and the dissolution equilibrium state of the fluid is controlled through the temperature change; by real-time monitoring the dynamic changes of the fluid (such as the volume of bubbles, the flow rate, and the flow direction), the system can timely and adaptively adjust the pressure to compensate for the change in the flow rate, which can avoid the disconnection between the pressure and the flow rate, ensure the uniformity of the fluid flow inside the system, reduce the impact of unstable factors on the equipment and the entire system, improve the system stability. At the same time, by dynamically monitoring the change in the flow rate and adaptively adjusting the pressure, ensure that the flow rate is within a reasonable range, avoid the influence of too high or too low flow rate on the subsequent treatment process. For example, too fast a flow rate may cause the particles in the fluid to be unable to be effectively separated, and too slow a flow rate may lead to low treatment efficiency. Maintaining an appropriate flow rate helps to improve the overall treatment efficiency, and by monitoring the temperature change and controlling the dissolution equilibrium state of the fluid, the system can accurately adjust the temperature conditions to ensure that the solubility of the gas in the liquid is in an ideal state. The control of the temperature helps the dissolution and release of gas and solid particles, and promotes the stable distribution and treatment effect of the fluid.

[0040] In this embodiment, the judgment module further includes: An identification unit, configured to identify the material properties of the fluid substance based on the fluid substance pre-collected in the vacuum return water tank, where the material properties specifically include grease, organic matter, and bubbles; A second judgment unit, configured to judge whether the fluid substance exceeds a preset phase concentration change; A second execution unit, which is configured to, if so, collect the phase concentration distribution of the fluid from the vacuum return water tank, obtain the concentration exceeding standard area in the vacuum return water tank according to the phase concentration distribution, and perform concentration stratification on the vacuum return water tank based on the concentration exceeding standard area, wherein the phase concentration distribution specifically includes a gas phase, a liquid phase, and a solid phase.

[0041] In this embodiment, the system identifies the physical properties of the fluid substances based on the fluid substances pre-collected in the vacuum return water tank. The physical properties specifically include grease, organic matter, and bubbles. Then, the system determines whether these fluid substances exceed the preset phase concentration change to execute corresponding steps. For example, when the system determines that the fluid substances do not exceed the preset phase concentration change, the system will consider that the current fluid state is within the normal range, and the physical proportion and concentration change of the fluid do not reach the critical point that requires intervention. The system will continue to monitor the fluid state to ensure that any change can be captured in a timely manner. At this time, regular data collection and status monitoring will continue to prevent potential changes from affecting the operation of the system. At the same time, regular analysis and monitoring of fluid substances will be carried out. The monitoring parameters include the concentration changes of grease, organic matter, and bubbles, as well as other possible physical parameters (such as temperature, pressure, flow rate, etc.). Through continuous data collection, the system can capture any abnormal changes in a timely manner, so as to take necessary measures before the concentration of fluid substances exceeds the standard, and dynamically optimize other relevant operation parameters (such as fluid temperature, pressure, or flow rate) according to the current concentration of fluid substances. Although these adjustments do not mean that the fluid has become abnormal, they help to further improve the overall operation efficiency and maintain the stable operation of the system. For example, when the system determines that the fluid substances exceed the preset phase concentration change, the system will consider that the current fluid state is abnormal. The system will collect the phase concentration distribution of the fluid from the vacuum return water tank. The phase concentration distribution specifically includes the gas phase, liquid phase, and solid phase. According to the different phase concentration distributions, the concentration exceeding standard areas in the vacuum return water tank will be obtained, and the vacuum return water tank will be stratified according to these concentration exceeding standard areas. By monitoring the phase concentration distributions of the gas phase, liquid phase, and solid phase, the system can accurately identify the specific areas where the concentration exceeds the standard, which can help to judge which areas of the fluid state are abnormal, especially the concentration fluctuation conditions in different areas of the vacuum return water tank. At the same time, when the concentration exceeding standard areas are identified, the system can focus on processing these areas. The system can adaptively adjust the operation mode of the separator according to the fluid characteristics of different areas according to the concentration stratification. For example, the exceeding standard gas area can be separated by gas-liquid separation, and the exceeding standard solid particle area can be separated by solid-liquid separation to process different phases more efficiently. And by locally processing the concentration exceeding standard areas, the system can effectively reduce the overall load of the equipment, avoid over-processing the normal fluid in other areas, reduce equipment wear, and extend the equipment life. A stable fluid treatment process can enable the system to continuously operate in the best state.

[0042] In this embodiment, the second judgment module further includes: A second identification unit, configured to identify the operating state of the working equipment based on the working equipment of the vacuum return water tank, where the working equipment specifically includes a pump, a valve drive, and a stirrer; A third judgment unit, configured to judge whether the operating state is affected by the change in the fluid property; A third execution unit, configured to, if so, generate an influence type of the working device according to the change in the fluid property, and detect an operating index of the working device according to the influence type, where the influence type specifically includes an increase in equipment load, an increase in power consumption, and an increase in pipeline pressure loss, and the operating index specifically includes a power consumption index, an operating environment index, and a chemical reaction index.

[0043] In this embodiment, the system is based on the working equipment of the vacuum return water tank. The working equipment specifically includes pumps, valve drives, and agitators. The system identifies the operating states of these working equipment, and then determines whether the operating states are affected by changes in fluid properties to perform corresponding steps. For example, when the system determines that the operating states of the working equipment are not affected by changes in fluid properties, the system will consider that the current fluid properties are within an acceptable range, and the working equipment is operating normally without being disturbed by abnormal fluid behaviors (such as viscosity changes, bubble generation, etc.). The system will continue to maintain the current operation settings, continue to monitor the states of the fluid and the working equipment to ensure that the equipment operates in a stable state. In the case of insignificant changes in fluid properties, excessive adjustment of operation parameters is avoided, while unnecessary energy consumption and material usage are reduced. For example, the rotation speed of the agitator is adjusted, the power output of the pump is reduced, and unnecessary equipment operation is avoided, thereby saving energy and material consumption. And by confirming that the fluid properties have no impact on the equipment operation, the stability of the system can be further verified, and the fault tolerance ability of the system to abnormal fluctuations can be improved. When the fluid properties change, the system can respond and adjust more quickly. For example, when the system determines that the operating states of the working equipment are affected by changes in fluid properties, at this time, the system will consider that the current fluid properties are unacceptable and the working equipment is prone to abnormalities. The system will generate the impact types of the working equipment according to the changes in fluid properties. The impact types specifically include increased equipment load, increased power consumption, and increased pipeline pressure loss. According to different impact types, the operating indicators of the working equipment are detected. The operating indicators specifically include power consumption indicators, operating environment indicators, and chemical reaction indicators. By detecting the power consumption, operating environment, and chemical reaction indicators, the system can timely detect abnormal situations such as increased equipment load and increased power consumption caused by changes in fluid properties, so as to give early warnings and avoid equipment failures due to overloading or overloading operation. At the same time, according to the impact types generated by the system, the system can dynamically adjust the parameters of the working equipment according to the actual operating state to ensure that the equipment can still operate efficiently and stably under the condition of changes in fluid properties. For example, the power of the pump is adjusted, the pipeline pressure is changed, or the opening of the valve is adjusted, etc., to avoid the negative impacts brought by changes in fluid properties. And by monitoring the pipeline pressure loss, the system can optimize the flow state of the fluid in the pipeline, reduce the pressure drop caused by changes in fluid properties, and thus reduce energy consumption and reduce energy waste caused by high-pressure losses. And according to the change in power consumption, the equipment operation mode is adjusted to avoid unnecessary energy consumption waste. For example, when the power consumption exceeds the standard, the system may achieve energy conservation by reducing the equipment load or optimizing the working conditions.

[0044] In this embodiment, the acquisition module further includes: An acquisition unit, configured to obtain the fluid change rate of the fluid based on a preset fluid acquisition point in the vacuum return water tank; A fourth judgment unit, configured to judge whether the fluid change rate matches a preset acquisition frequency; A fourth execution unit, configured to, if not, perform multiple samplings at the fluid acquisition point, collect the fluid property differences of the fluid, and generate the distribution and flow trend of the fluid in the vacuum return water tank according to the fluid property differences, where the fluid property differences specifically include temperature differences, pressure differences, flow velocity differences, and bubble gas content differences.

[0045] In this embodiment, the system obtains the fluid change rate of the fluid based on the preset fluid acquisition points in the vacuum return water tank, and then the system judges whether the fluid change rate matches the preset acquisition frequency to execute corresponding steps; for example, when the system determines that the fluid change rate of the fluid can match the preset acquisition frequency, the system will consider that the fluid data can be acquired and monitored at an appropriate frequency, which means that the system can accurately and timely record the state changes of the fluid, ensuring the effectiveness and timeliness of the data. The system will continue to stably acquire fluid data at the set frequency to ensure the timeliness and accuracy of the data. At the same time, the matching fluid change rate and acquisition frequency ensure that the system can continuously and stably monitor the state of the fluid, so that the system can continuously track the changes of the fluid, not miss key data points, and when the fluid change rate and acquisition frequency match, the system avoids meaningless over-acquisition of data, thereby avoiding excessive occupation of computing and storage resources and ensuring the efficient operation of the system; for example, when the system determines that the fluid change rate of the fluid cannot match the preset acquisition frequency, at this time, the system will consider that the fluid data cannot be acquired and monitored at an appropriate frequency, and the system will perform multiple samplings at the fluid acquisition point to collect the fluid property differences of these fluids. The fluid property differences specifically include temperature differences, pressure differences, flow velocity differences, and bubble gas content differences. According to different fluid property differences, the distribution and flow trend of the fluid in the vacuum return water tank are generated; through multiple samplings, the system can capture the changes in fluid properties at different time points and positions, ensuring a more comprehensive understanding of the behavior and changes of the fluid. Especially when the fluid change rate is large, this method can make up for the deficiency that a single sampling cannot fully cover the fluid state. At the same time, the collection of fluid property differences (such as temperature, pressure, flow velocity, bubble gas content, etc.) can help the system identify the distribution trend of the fluid in the vacuum return water tank, capture different levels and dynamic changes of the fluid, and through multiple samplings of fluid properties at different positions and time points, the system can discover potential non-uniform distribution problems. For example, problems such as uneven bubble distribution and large flow velocity differences can be effectively identified by this method, and the system can take corresponding optimization measures (such as adjusting pressure, operating the agitator, etc.) accordingly to improve the distribution and flow state of the fluid.
