Description

Technical Field

[0001] The utility model relates to a device for simulating antibiotic photodegradation, belonging to the field of photochemical reaction test equipment. Background Art

[0002] New pollutants refer to toxic and hazardous chemicals with characteristics such as biological toxicity, environmental persistence, and bioaccumulation. Antibiotics are one of the four major categories of new pollutants that have attracted widespread attention both domestically and internationally. my country is a major user of antibiotics, and traditional sewage treatment processes have a low efficiency in removing antibiotics, making natural water bodies the final destination of antibiotics. Photodegradation is an important way to remove antibiotic pollution. By conducting antibiotic photodegradation simulation experiments in a simulated solution system by changing the solution pH, antibiotic type and initial concentration, photosensitizer type and concentration, illumination time, and spectral range, determining its degradation rate, and clarifying the optimal reaction conditions for photodegradation, it is the basis for conducting research on the photochemical degradation mechanism of antibiotics.

[0003] Currently, the equipment used in photodegradation experiments includes commercially available equipment and custom-made experimental setups. Integrated xenon lamp light source systems, including a xenon lamp source box and thermal management system, are point-based. However, xenon lamps are point-based and can only illuminate one sample at a time, resulting in low experimental efficiency and limiting their application in applications requiring simultaneous reactions of multiple samples. Photochemical reactors also require numerous accessories, occupy a large area, consume a lot of energy, and are expensive, making them difficult to widely promote in university experimental teaching and research.

[0004] Homemade photodegradation experimental setups typically use a tube-type light source—a long-arc xenon lamp—coupled with a double-layer quartz cold trap, enabling simultaneous reactions in multiple test tubes. However, this internally illuminated light source is difficult to install filters and cannot filter out radiation in characteristic wavelengths, making it difficult to study the effects of specific wavelengths on pollutant degradation. Furthermore, some home-made setups fail to account for heat dissipation within the reaction tubes. Utility Model Content

[0005] In response to the above-mentioned problems in the prior art, the present invention provides a simple device for simulating the photodegradation of antibiotics on a laboratory scale. While ensuring that multiple samples can be subjected to photodegradation experiments simultaneously, it can solve the light filtering problem and achieve effective heat dissipation of the reaction device.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a multi-station large-capacity device for simulating antibiotic photodegradation, characterized in that it includes a xenon lamp power adapter and a black reaction dark box; an iron stand is provided in the black reaction dark box; one side of the iron stand is connected to a double-layer quartz cold trap through a clamping mechanism; a long arc xenon lamp is suspended inside the double-layer quartz cold trap; one side of the long arc xenon lamp is connected to a xenon lamp power adapter; a plurality of quartz test tubes are provided on the annular test tube holder; the double-layer quartz cold trap, the long arc xenon lamp, the annular test tube holder and the assembly including the quartz test tubes are arranged as a whole in a beaker with upper and lower nozzles.

[0007] Furthermore, the clamping mechanism on one side of the iron frame is a three-claw clamp mechanism, which is connected to the iron frame through a connecting rod, and the connecting rod and the three-claw clamp are integrally formed.

[0008] Furthermore, the double-layer quartz cold trap is placed at the center of the annular test tube holder.

[0009] Furthermore, the annular test tube holder is a ten-channel placement holder, which includes 10 quartz test tube placement positions.

[0010] Furthermore, a small hole is provided on the left side panel of the black reaction dark box for the water inlet pipe of the upper and lower beakers to pass through; a small hole is provided on the right side panel of the black reaction dark box for the water outlet pipe of the upper and lower beakers to pass through. The water inlet pipe of the upper and lower beakers is connected to cooling water to achieve the purpose of heat dissipation.

[0011] Furthermore, the outer cavity of the double-layer quartz cold trap is filled with a filter liquid, which is slowly injected through the sample injection port of the double-layer quartz cold trap. The filter liquid is connected to a micro peristaltic pump to achieve the purpose of heat dissipation.

[0012] Furthermore, a small fan is provided above the entire device assembly inside the black reaction dark box; the small fan is installed at the top of the black reaction dark box; the power cord of the small fan passes through a small hole reserved at the top of the black reaction dark box and is connected to a wall power socket.

[0013] The beneficial effects of the utility model are:

[0014] 1. Its multi-station, large-capacity design meets the requirements for simultaneous laboratory-scale multi-test-tube reactions. This device can be used to optimize reaction conditions for antibiotic photodegradation. By adjusting reaction conditions (such as pH and illumination duration), regularly sampling and measuring antibiotic concentration, and monitoring the reaction progress in real time, researchers can quickly and efficiently identify optimal photodegradation conditions.

[0015] 2. Improve experimental accuracy and safety. By using a black reaction darkroom, the device effectively prevents interference from indoor light on samples, ensuring the accuracy of experimental data. In addition, the darkroom design also protects the experimenter, avoiding prolonged exposure to light sources and effectively reducing the risk of eye burns caused by light.

[0016] 3. Filter design and efficient heat dissipation. Using filter fluid instead of traditional filters not only reduces costs but also increases operational flexibility, allowing for quick replacement of different filter fluids to accommodate different wavelength experiments. Using beakers with upper and lower nozzles to connect to cooling water allows for efficient heat dissipation, ensuring continuous experimentation.

[0017] 4. Energy and resource conservation. The photodegradation device has low energy consumption, readily available materials, and a highly economical overall design. This meets the current requirements for building a resource-saving society and promotes environmental protection and sustainable development.

[0018] 5. Modular design and easy operation: The modular design of each component makes the assembly and disassembly of the device simple, making it easier for experimenters to maintain and debug the equipment. In addition, the front panel can be moved upward to facilitate rapid sample collection and improve the efficiency of the experiment. BRIEF DESCRIPTION OF THE DRAWINGS
