Description

Technical Field

[0001] This invention relates to the field of ozone water technology, and more particularly to a system and method for maintaining the concentration of electrolyzed ozone water during transportation. Background Technology

[0002] Electrolyzed ozone water is widely used in medical disinfection, food processing, and agricultural irrigation due to its strong oxidizing properties, broad-spectrum bactericidal ability, and residue-free characteristics. However, electrolyzed ozone water is a thermodynamically unstable system. Ozone spontaneously decomposes into oxygen in water, and its half-life is affected by factors such as temperature, pH value, and impurities in the water, typically only a few tens of minutes at room temperature.

[0003] In practical applications, electrolyzed ozone water often needs to be transported over long distances and for extended periods by vehicles (such as tank trucks and drum trucks). During transportation, factors such as bumps, temperature changes (especially inadequate protection against high temperatures in summer or low temperatures in winter), and pressure fluctuations can further accelerate the decomposition of ozone, resulting in a significant drop in ozone concentration upon arrival at the destination, sometimes even below the minimum threshold required for use, severely impacting the effectiveness and user experience.

[0004] In existing technologies, this problem is usually circumvented by either "preparing and using immediately" or "preparing in excess". "Preparing and using immediately" limits the scope of application; "preparing in excess" poses safety hazards (high concentrations of ozone are harmful to the human body), and due to the uncertainty of the decomposition rate, it is difficult to accurately control the final concentration, resulting in waste of reagents or failure to meet the standards.

[0005] Therefore, there is an urgent need to develop a system and method that can actively maintain a stable ozone concentration during transportation. Summary of the Invention

[0006] This invention aims to at least partially solve the technical problems in related technologies. Therefore, the first objective of this invention is to provide an intelligent, dynamically compensated concentration maintenance system for the transportation of electrolyzed ozone water. This system overcomes the shortcomings of existing technologies, such as rapid concentration decay and inaccurate control of electrolyzed ozone water during long-distance transportation. This system can monitor ozone concentration and environmental parameters in real time during transportation and automatically activate an electrolysis compensation mechanism based on a preset target concentration to offset natural decomposition losses during transportation, ensuring that the ozone water maintains a set, constant, and effective concentration upon arrival at its destination.

[0007] The second objective of this invention is to provide a method for maintaining the concentration of electrolyzed ozone water during transportation.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solution: A concentration maintenance system for transporting electrolyzed ozone water includes: a transport container module, a real-time monitoring module, an intelligent control module, a dynamic electrolysis compensation module, and an energy supply module. The real-time monitoring module is used to collect concentration and temperature data of the ozone water in the transport container module. The intelligent control module is used to control the dynamic electrolysis compensation module to perform in-situ electrolysis based on the collected data and a preset target concentration of ozone water to supplement the ozone decomposition consumption during transportation. The energy supply module is used to supply power to the real-time monitoring module, the intelligent control module, and the dynamic electrolysis compensation module.

[0009] Preferably, the real-time monitoring module includes an ozone concentration sensor, a temperature sensor, and a pH sensor.

[0010] Preferably, the intelligent control module has a built-in ozone concentration decay prediction model based on temperature and transportation time; the intelligent control module is specifically used for: Based on the current ozone water concentration, temperature, and ozone concentration decay prediction model, the ozone concentration at the destination is predicted without compensation during the remaining transportation time. If the concentration is lower than the preset target ozone water concentration, the amount of ozone to be replenished is calculated based on the concentration difference. Then, based on the electrolysis efficiency, the amount of ozone to be replenished is converted into the required electrolysis current density and electrolysis time. This allows control of the power adjustment unit in the dynamic electrolysis compensation module to dynamically adjust the electrolysis power and electrolysis time, generating ozone in situ to replenish the ozone decomposition and consumption during transportation.

[0011] Preferably, the dynamic electrolysis compensation module includes a portable electrolytic cell, a high ozone overpotential electrode, and the power adjustment unit, wherein the high ozone overpotential electrode is made of boron-doped diamond or β-PbO2.

[0012] Preferably, the transport container module has a guide plate inside or a circulation pump outside to form a liquid circulation loop, and the dynamic electrolysis compensation module is set on the liquid circulation loop.

[0013] Preferably, the outer wall of the transport container module is provided with an insulation layer or a temperature control layer.

[0014] Preferably, the energy supply module includes an on-board power interface, a built-in rechargeable battery pack, and a solar-assisted power supply module.

[0015] To achieve the above objectives, a second aspect of the present invention provides a method for maintaining the concentration of electrolyzed ozone water during transportation, applied to the aforementioned concentration maintenance system for electrolyzed ozone water transportation, the method comprising: The preset target concentration of ozone water and the estimated transportation time are set through the intelligent control module; The ozone water concentration and temperature data are collected at a set frequency through the real-time monitoring module and sent to the intelligent control module. The intelligent control module determines the remaining transportation time based on the estimated transportation time, and predicts the concentration at the destination without compensation in the case of no compensation in the remaining transportation time based on the current ozone water concentration, temperature and ozone concentration decay prediction model. When the concentration is lower than the preset ozone water target concentration, concentration compensation is initiated. After concentration compensation is initiated, the amount of ozone to be replenished is calculated based on the concentration difference. Then, based on the electrolysis efficiency, the amount of ozone to be replenished is converted into the required electrolysis current density and electrolysis time. This allows control of the power adjustment unit in the dynamic electrolysis compensation module to dynamically adjust the electrolysis power and electrolysis time, generating ozone in situ to replenish the ozone decomposition loss during transportation.

[0016] Preferably, the method further includes: continuously monitoring the ozone water concentration during and after the electrolysis compensation process; if the ozone water concentration reaches the preset target concentration, then electrolysis is stopped; if it does not reach the target concentration, then the parameters are adjusted for compensation.

[0017] Preferably, the method further includes: generating a concentration change curve of the electrolyzed ozone water throughout the transportation process, and issuing an audible and visual alarm or a remote alarm when an abnormal concentration is detected based on the concentration change curve.

[0018] This invention has at least the following technical effects: (1) Constant concentration: This invention breaks through the limitations of traditional "static transportation". Through the "dynamic monitoring + active compensation" mechanism, it effectively offsets the ozone decomposition loss during transportation, ensures that the final concentration accurately meets the standard, and solves the industry pain point of "transportation attenuation".

[0019] (2) High level of intelligence: It has built-in prediction models and intelligent algorithms, which can automatically adjust the compensation strategy according to factors such as ambient temperature and transportation time, without the need for manual intervention and easy to operate.

[0020] (3) Good safety: It avoids the high concentration safety hazards caused by traditional "over-preparation". The system always controls the concentration within the target range, which is both safe and economical.

[0021] (4) Strong applicability: The system is modularly designed and can be flexibly installed on various sizes of transport vehicles, storage tanks or turnover barrels, and is suitable for ozone water transportation in various scenarios such as medical, food and agriculture.

[0022] (5) Energy saving and environmental protection: electrolysis on demand avoids unnecessary energy waste and excessive ozone emissions.

[0023] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0024] Figure 1 This is a structural block diagram of the concentration maintenance system during the transportation of electrolyzed ozone water according to an embodiment of the present invention.

[0025] Figure 2 This is a flowchart of a method for maintaining the concentration of electrolyzed ozone water during transportation, according to an embodiment of the present invention. Detailed Implementation

[0026] The following describes this embodiment in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0027] The concentration maintenance system and method for transporting electrolyzed ozone water according to this embodiment are described below with reference to the accompanying drawings.

[0028] Figure 1 This is a structural block diagram of the concentration maintenance system during the transportation of electrolyzed ozone water according to an embodiment of the present invention. Figure 1 As shown, the system includes a transport container module, a real-time monitoring module, an intelligent control module, a dynamic electrolysis compensation module, and an energy supply module. The transport container module, real-time monitoring module, intelligent control module, and dynamic electrolysis compensation module are connected in sequence, and the energy supply module is connected to the real-time monitoring module, intelligent control module, and dynamic electrolysis compensation module to supply power to each module.

[0029] In this embodiment, the real-time monitoring module is used to collect the concentration and temperature data of ozone water in the transport container module; the intelligent control module is used to control the dynamic electrolysis compensation module to perform in-situ electrolysis based on the collected data and the preset ozone water target concentration, so as to supplement the ozone decomposition consumption during the transportation process.

[0030] Specifically, the transport container module is used to hold electrolyzed ozone water, including transport tanks, barrels, or storage bags, and is sealed and pressure-resistant. A real-time monitoring module is installed inside the transport container or on the bypass circulation pipeline to collect real-time data on the concentration, temperature, and pH (hydrogen ion concentration index) of the ozone water. An intelligent control module communicates with the real-time monitoring module, receives and processes the monitoring data, and has a built-in ozone concentration decay prediction model based on temperature and transport time, along with a PID (proportional-integral-derivative) control algorithm, to calculate the compensation electrolysis parameters required to maintain the preset target concentration of ozone water. A dynamic electrolysis compensation module is installed inside the transport container module or on the bypass circulation pipeline (i.e., the liquid circulation loop), and includes a portable electrolyzer, a high-emission ozone overpotential electrode, and a power adjustment unit. The intelligent control module controls the power adjustment unit, dynamically adjusting the electrolysis power and electrolysis time based on the calculation results, generating ozone in situ to compensate for decomposition losses during transport. An energy supply module provides power to the entire system, including an onboard power interface, a built-in rechargeable lithium battery pack, or a solar-assisted power supply module.

[0031] Furthermore, the real-time monitoring module includes an ozone concentration sensor, a temperature sensor, and a pH sensor. The ozone concentration sensor employs either an electrochemical or ultraviolet absorption method to monitor the dissolved ozone concentration in the water in real time. The temperature sensor monitors water temperature, as temperature is a key factor affecting the ozone decomposition half-life (higher temperatures result in faster decomposition). The pH sensor monitors the acidity or alkalinity of the water, aiding in the assessment of water quality.

[0032] Furthermore, the concentration decay prediction model built into the intelligent control module, based on the Arrhenius equation and historical experimental data, can predict future concentration decay trends according to the current temperature, initial concentration, and remaining transport time.

[0033] Specifically, the intelligent control module predicts the ozone concentration at the destination without compensation during the remaining transportation time based on the current ozone water concentration, temperature, and ozone concentration decay prediction model. When the concentration is lower than the preset target ozone water concentration, it calculates the amount of ozone that needs to be replenished based on the concentration difference. Based on the electrolysis efficiency, it converts the amount of ozone that needs to be replenished into the required electrolysis current density and electrolysis time, so as to control the power adjustment unit in the dynamic electrolysis compensation module to dynamically adjust the electrolysis power and electrolysis time, generate ozone in situ, and replenish the ozone decomposition consumption during transportation.

[0034] Furthermore, the dynamic electrolysis compensation module adopts low-voltage DC electrolysis technology or pulse electrolysis technology, and the electrode material is a high ozone overpotential material, such as boron-doped diamond electrode or β-PbO2 electrode, which can ensure efficient and stable ozone generation.

[0035] Furthermore, the transport container module is equipped with a flow guide plate inside or a circulation pump outside to form a liquid circulation loop. The liquid circulation loop can ensure that the ozone generated by electrolysis can be quickly and evenly mixed into the water in the entire container, avoiding local concentrations that are too high or too low.

[0036] Furthermore, the outer wall of the transport container module is equipped with an insulation layer or a temperature control layer, which can be used to help mitigate the impact of drastic changes in external temperature on the water body.

[0037] Furthermore, the present invention also provides a method for maintaining the concentration during the transportation of electrolyzed ozone water, applicable to the aforementioned concentration maintenance system during the transportation of electrolyzed ozone water, such as... Figure 2 As shown, the method includes: Step S1: Set the preset target concentration of ozone water and the estimated transportation time through the intelligent control module.

[0038] Step S2: Collect ozone water concentration and temperature data at a set frequency through the real-time monitoring module and send them to the intelligent control module.

[0039] Step S3: The intelligent control module determines the remaining transportation time based on the estimated transportation time, and predicts the concentration at the destination without compensation in the case of no compensation in the remaining transportation time according to the current ozone water concentration, temperature and ozone concentration decay prediction model. When the concentration is lower than the preset ozone water target concentration, concentration compensation is initiated.

[0040] Step S4: After starting concentration compensation, calculate the amount of ozone that needs to be replenished based on the concentration difference, and convert the amount of ozone that needs to be replenished into the required electrolysis current density and electrolysis time based on the electrolysis efficiency, so as to control the power adjustment unit in the dynamic electrolysis compensation module to dynamically adjust the electrolysis power and electrolysis time, generate ozone in situ, and replenish the ozone decomposition consumption during transportation.

[0041] It should be noted that the start-up timing and electrolysis parameters of dynamic electrolysis compensation are automatically determined by the intelligent control module based on the difference between the predicted endpoint concentration and the target concentration.

[0042] In one embodiment of the present invention, the method further includes continuously monitoring the change in ozone water concentration during and after the electrolysis compensation process. If the ozone water concentration reaches the preset target concentration, electrolysis is stopped; if it does not reach the target concentration, the parameters are adjusted for compensation.

[0043] In one embodiment of the present invention, the method further includes generating a concentration change curve of the electrolyzed ozone water throughout the transportation process, and issuing an audible and visual alarm or a remote alarm when an abnormal concentration is determined based on the concentration change curve.

[0044] Specifically, the method includes the following steps: (1) Setting stage: After the water filling is completed, the user sets the target ozone concentration value C_target and the estimated transportation time T through the intelligent control module.

[0045] (2) Monitoring phase: After the transportation starts, the real-time monitoring module collects data such as ozone concentration C_real and water temperature T_water at a set frequency (e.g., per minute) and transmits them to the intelligent control module.

[0046] (3) Prediction and calculation stage: The intelligent control module predicts the concentration C_predict when reaching the destination without compensation based on the current concentration, temperature and decay model. If C_predict is lower than C_target, the compensation procedure is initiated.

[0047] (4) Dynamic compensation stage: The intelligent control module calculates the amount of ozone that needs to be replenished, ΔC, and converts it into the required electrolysis current density i and time t based on the electrolysis efficiency, and controls the dynamic electrolysis compensation module to work.

[0048] (5) Feedback adjustment stage: During and after the electrolysis compensation process, the concentration change is continuously monitored. If the target is reached or the predicted target is met, electrolysis is stopped; if it is still insufficient, the parameters are adjusted for compensation.

[0049] (6) Recording and alarm stage: The system records the concentration change curve throughout the transportation process and issues an audible and visual alarm or remote alarm when the concentration is abnormal (too high or too low).

[0050] As a specific example, a system for maintaining stable concentration of electrolyzed ozone water during long-distance transportation is installed on a 5-ton ozone water transport vehicle.

[0051] Transport container module: a stainless steel insulated tank with a volume of 5m³, polished inner wall, and a 50mm polyurethane insulation layer on the outside.

[0052] Real-time monitoring module: An immersion-type electrochemical ozone sensor, a PT100 temperature sensor, and a pH sensor are installed on the top of the tank, and the data cable is connected to the control cabinet.

[0053] Intelligent control module: It is a waterproof and shockproof industrial-grade control box containing a microcontroller (MCU) or PLC controller, and is pre-installed with an ozone decay prediction algorithm based on temperature compensation.

[0054] Dynamic electrolysis compensation module: A set of titanium-based boron-doped diamond (BDD) electrode plates is installed longitudinally inside the tank and connected to an adjustable pulse power supply in the control box. Simultaneously, a circulation pump is installed at the bottom of the tank, with its outlet located at the upper part of the other end of the tank, forming a large circulation loop.

[0055] Energy supply module: It uses the vehicle's own 24V DC power supply and is equipped with a 50Ah lithium iron phosphate battery as a backup power source.

[0056] Workflow: 1) At the water source, staff poured the prepared ozone water (initial concentration 10ppm) into the tank.

[0057] 2) Set the target concentration to 8 ppm via the touch screen on the control box, with an estimated transportation time of 6 hours.

[0058] 3) Transportation begins, and the monitoring module starts working. The system detects that the current water temperature is 25℃. According to the model prediction, the concentration will decrease to 6.5ppm after 6 hours, which is lower than the target value.

[0059] 4) The intelligent control module calculates that 1.5 ppm of ozone needs to be added. The system starts the circulation pump and electrolysis power supply to electrolyze the flowing water with a current of 5A.

[0060] 5) After a 10-minute electrolysis cycle, the real-time monitoring module showed that the concentration had risen back to 9.8 ppm. The system stopped electrolysis and entered a dormant monitoring state.

[0061] 6) During transportation, when the system predicts that the degradation will be accelerated due to the rise in external temperature (such as rising to 30°C), it will automatically wake up again to perform a short-term micro-electrolysis replenishment.

[0062] 7) Six hours later, the vehicle arrived at its destination, and the testing personnel took samples for analysis. The ozone concentration in the water was 8.1 ppm, which fully meets the usage requirements.

[0063] In summary, this invention provides a system and method for maintaining stable concentration of electrolyzed ozone water during long-distance transportation. The system integrates a real-time monitoring module, an intelligent control module, and a dynamic electrolysis compensation module on the transport container. During transportation, the system monitors ozone concentration and water temperature in real time, calculates future concentration loss using a decay prediction model, and automatically controls the electrolysis module to replenish ozone in situ with trace amounts, thereby offsetting natural decomposition during transportation and ensuring that the ozone water maintains the set target concentration upon arrival at its destination. This invention can monitor, dynamically compensate for, and maintain stable concentration of electrolyzed ozone water in real time, solving the problem of uncontrollable concentration decay during long-distance transportation of electrolyzed ozone water. It features intelligence, precision, safety, and efficiency, and is applicable to scenarios such as transport vehicles and logistics containers for bottled / canned ozone water.
