[0020] The embodiments disclosed herein aim to address the following shortcomings of existing advanced ozone oxidation experimental devices: low ozone utilization rate, with some unreacted ozone being directly emitted, resulting in resource waste and safety hazards; fixed reaction device structure, making it difficult to adjust the contact mode and reaction time between ozone and wastewater; lack of an effective catalyst addition and recovery system, which is not conducive to experimental research on catalytic ozone oxidation; low precision in ozone concentration and flow control, affecting the repeatability of experimental data; and inadequate exhaust gas treatment, posing a risk of ozone leakage and endangering the health of experimental personnel. In view of this, the present disclosure proposes a wastewater O3 advanced oxidation purification device, which integrates five modules—liquid inlet, electrical control, main reaction, ozone regulation, and tail gas treatment—through a support frame. This allows for a direct demonstration of the entire advanced ozone oxidation process: the double-layered high borosilicate jacketed main reactor is temperature resistant from -30 to 200℃ and has a light transmittance of ≥90%. Combined with a bottom microporous gas distribution plate, ozone is uniformly dispersed in the form of microbubbles, improving gas-liquid mass transfer efficiency by 30%, and the reaction process is visible to the naked eye; the ozone dosing is infinitely adjustable within the range of 1–50 g / h and 5–100 mg / L (±0.1 L / min), meeting the needs of various water quality comparison experiments; the 300℃ heated catalytic + 5% potassium permanganate absorption tower tail gas system reduces residual ozone to ≤0.01 mg / m³ in real time, achieving zero leakage and zero odor, ensuring the safety of teaching and research sites; the overall modular, visual, and high-precision design simplifies experimental operation, improves data reproducibility, and significantly enhances the efficiency of experimental teaching demonstrations and scientific comparative studies.
[0021] like Figure 1 As shown, a wastewater O3 advanced oxidation purification device includes a support frame 1, a liquid inlet device 2, an electrical control device 3, a main reactor 4, an ozone generation and control system 6, and a tail gas treatment system 7. The liquid inlet device 2 is installed at the bottom of the support frame 1, the electrical control device 3 is installed above the support frame 1, and the main reactor 4 is installed to the right of the electrical control device 3. The main reactor 4 is used to observe the reaction process. The ozone generation and control system 6 is installed on one side of the main reactor 4 and is used for precise control of ozone concentration and flow rate. The tail gas treatment system 7 is installed on the main reactor 4 and is used to remove residual ozone, meeting environmental protection requirements. The support frame 1 integrates five modules: liquid inlet, electrical control, main reaction, ozone regulation, and tail gas treatment. This allows for a direct demonstration of the entire advanced ozone oxidation process: the double-layered high borosilicate jacketed main reactor 4 is temperature resistant from -30 to 200℃ and has a light transmittance of ≥90%. Combined with a bottom microporous gas distribution plate, it uniformly disperses ozone in the form of microbubbles, improving gas-liquid mass transfer efficiency by 30%, and making the reaction process visible to the naked eye. The stepless ozone dosing rate of ±0.1L / min within the range of 1–50g / h and 5–100mg / L meets the needs of various water quality comparison experiments. The 300℃ heated catalytic + 5% potassium permanganate absorption tower tail gas system reduces residual ozone to ≤0.01mg / m³ in real time, achieving zero leakage and zero odor, ensuring the safety of teaching and research sites. The overall modular, visual, and high-precision design simplifies experimental operation, improves data reproducibility, and significantly enhances the efficiency of experimental teaching demonstrations and scientific comparative studies.
[0022] like Figure 1 As shown, the ozone generation and control system 6 includes an ozone generator 61 and a mass flow controller 62. The ozone generator 61 is installed inside the support frame 1, and the mass flow controller 62 is installed between the ozone generator 61 and the main reactor 4 and fixed on the support frame 1. The ozone output adjustment range is 1-50 g / h, the ozone concentration can be precisely controlled within the range of 5-100 mg / L, and the gas flow control accuracy is ±0.1 L / min. The above design integrates ozone generator 61 and mass flow controller 62 into a single closed-loop circuit, combining three control parameters: ozone output, concentration, and gas flow rate. This enables stepless, repeatable, and digital fine-tuning of output (1–50 g / h), concentration (5–100 mg / L), and flow rate (±0.1 L / min). This not only allows the advanced oxidation reaction to respond instantaneously to water quality fluctuations at the optimal ozone dosage, significantly improving the removal rates of COD, color, and characteristic pollutants, but also avoids excessive ozone waste and exhaust emissions, reducing operating costs by more than 20%. Simultaneously, it ensures stable ozone dosage and reproducible reaction conditions during continuous operation, providing a highly accurate data interface for subsequent process optimization and intelligent control.
[0023] like Figure 1 As shown, an ozone distribution device 41 is installed at the bottom of the main reactor 4. The ozone distribution device 41 is used to uniformly inject ozone into the interior of the main reactor 4. The addition of the ozone distribution device 41 at the bottom of the main reactor 4 allows the ozone to be uniformly and stably dispersed in the wastewater phase in the form of microbubbles, instantly improving the gas-liquid mass transfer efficiency by more than 30%, ensuring full contact between the oxidant and pollutants, shortening the reaction time by 20%, eliminating local over-ozonolysis, reducing the generation of by-products, improving the removal rate of COD, color and characteristic pollutants, and reducing the ozone dosage by 10%, thus achieving a high-efficiency, energy-saving and low-consumption advanced oxidation treatment effect.
[0024] like Figure 1 As shown, the exhaust gas treatment system 7 includes an exhaust gas collection pipe 71, an ozone destroyer and an absorption tower 72, and an ozone detector 73. The exhaust gas collection pipe 71 is installed above the main reactor 4. The ozone destroyer and the absorption tower 72 are installed at the end of the exhaust gas collection pipe 71, and the ozone detector 73 is installed on the exhaust gas absorption pipe. The ozone destroyer uses a catalytic decomposition method with heating at 300℃. The absorption tower is filled with a 5% potassium permanganate solution as an absorbent to ensure that the ozone concentration in the exhaust gas is ≤0.01mg / m³. The exhaust gas treatment system 7 couples catalytic decomposition at 300℃ with absorption by a 5% potassium permanganate solution in two stages: first, a high-concentration ozone is instantly broken down into oxygen by an ozone destroyer, and then residual ozone is captured by an absorption tower. The ozone detector 73 provides real-time closed-loop feedback to ensure that the emission concentration is ≤0.01mg / m³, far below the limit. This achieves zero ozone leakage in the exhaust gas, eliminates ecological risks during the experiment, avoids ozone corrosion of downstream pipelines, extends equipment life, and recovers some oxygen resources, reducing subsequent exhaust volume and energy consumption, making the entire advanced oxidation unit safe, green, and low-consumption.
[0025] like Figure 1 As shown, the main reactor 4 has a double-layer jacket structure. The double-layer jacket main reactor 4 forms an independent temperature-controlled flow channel in the jacket, which can be circulated with cooling water or heating medium to precisely lock the reaction temperature in the range of ±1℃. This not only prevents ozone from self-decomposing at high temperatures and improves oxidation efficiency by more than 10%, but also avoids the deposition of low-temperature by-products. The jacket also acts as a heat insulation layer, keeping the outer wall temperature below 40℃, eliminating the risk of burns to operators and reducing heat loss, thus achieving energy-saving, safe, and stable long-term operation.
[0026] like Figure 1 As shown, the main reactor 4 is made of high borosilicate glass and is integrally molded with high borosilicate glass. It has a transmittance of ≥90% ultraviolet-visible light and the ability to withstand rapid temperature changes from -30 to 200℃. The entire ozone oxidation process can be directly observed online, which is convenient for real-time control. Its chemical inertness can resist the synergistic corrosion of strong oxidants, acids, alkalis and organic solvents. The metal ion leaching amount is <0.1ppm, avoiding catalytic side reactions, ensuring stable effluent water quality, and reducing scale buildup and cleaning frequency by 50%. It achieves advanced oxidation treatment that is visualized, highly pure and low-maintenance.
[0027] The overall working process is as follows: Wastewater to be treated is injected into the main reactor 44, and parameters such as ozone concentration and flow rate are set through the control system 1. The ozone generator 618 is started, and ozone enters the reaction module through the gas pipeline to react with the wastewater; under the influence of catalyst 5, an ozone oxidation-reduction reaction takes place. During the reaction, the influent flow rate and the ozone flow rate are controlled to regulate the contact reaction time and improve reaction efficiency. The exhaust gas generated by the reaction enters the exhaust gas treatment system 7 for treatment before being discharged. During the experiment, various parameters are displayed in real time and automatically recorded. After the experiment, the data can be exported for analysis.
[0028] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
