Description

Technical Field

[0001] This utility model relates to the field of photocatalysis technology, and in particular to a photocatalytic glass plate reactor. Background Technology

[0002] A photocatalytic glass plate reactor is a device used for photocatalytic reactions. It combines the structural features of a plate reactor with the light transmittance of glass materials and is commonly used in research fields such as wastewater treatment, air purification, and energy catalysis (e.g., photocatalytic water splitting for hydrogen production and CO2 reduction).

[0003] Traditional plate reactors often suffer from excessively high lamp plate temperatures. This is mainly due to the low energy efficiency of traditional mercury lamps and xenon lamps, where most of the input electrical energy is converted into infrared thermal radiation rather than effective light energy. This leads to excessively high lamp body temperatures, directly causing thermal sintering and deactivation of catalyst nanoparticles. This reduces their specific surface area and permanently decreases the number of active sites, slowing down the reaction rate. High temperatures also cause thermal disturbances to the reaction system, potentially triggering unnecessary side reactions or causing material evaporation and altering the reaction conditions. Therefore, to address these issues, a photocatalytic glass plate reactor is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a photocatalytic glass plate reactor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A photocatalytic glass plate reactor includes a reaction chamber. A reaction assembly is installed inside the reaction chamber. The reaction assembly includes a glass clamping plate and a water-cooling plate. LED light panels are provided on both sides of the water-cooling plate. A water-cooling pressure plate is provided on the side of the two LED light panels away from the water-cooling plate. A glass reaction plate is installed on the side of the water-cooling pressure plate away from the LED light panels. The wavelength and light intensity of the LED light panels are adjustable. The two water-cooling pressure plates are interconnected with the water-cooling plate. A condenser is installed inside the reaction chamber, and condensing fans are symmetrically installed on the condenser. The condenser and condensing fans are used for heat dissipation of the water-cooled pressure plate.

[0006] The above technical solution further includes: The reaction assembly also includes a support plate installed inside the reaction chamber. A second support seat is symmetrically fixedly installed on the support plate. The second support seat is fixedly connected to the glass reaction plate and the water-cooled pressure plate. A first support seat is fixedly installed on the support plate. The first support seat is fixedly connected to the clamping seat. The glass clamping plate is fixedly connected to the clamping seat.

[0007] The top of the glass reaction plate is provided with a first feed port and a second feed port. The water-cooled pressure plate is provided with a water inlet and a water outlet on the side away from the clamping seat. The side of the glass clamping plate is provided with a discharge port that communicates with the glass reaction plate. The glass clamping plate is provided with a heating water inlet and a heating water outlet. The heating water inlet and the heating water outlet are used to provide a temperature environment for the reaction of the glass reaction plate.

[0008] A condenser is installed inside the reaction chamber, and condenser fans are symmetrically installed on the condenser. A water-cooled outlet connected to the water inlet and a water-cooled inlet connected to the water outlet are installed through the condenser.

[0012] The reaction chamber is equipped with a first safety valve connected to the first feed port and a second safety valve connected to the second feed port, and a pressure gauge is also installed on the reaction chamber.

[0013] This utility model has the following beneficial effects: In this invention, LED light panels arranged symmetrically on both sides are used as cold light sources, which reduces heat generation at the source. A water-cooled plate is set between the two LED light panels, and a condenser and a condensing fan are connected to the water-cooled plate to achieve efficient forced cooling of the reaction area and solve the problem of catalyst thermal sintering deactivation caused by excessively high light panel temperature.

[0014] In this invention, the reaction temperature at the glass reaction plate is strictly controlled by the compressor, circulating pump, plate heat exchanger, water-cooled radiator, and water-cooled fan built into the reaction chamber, keeping the temperature fluctuation in the core reaction area within a very small range. This is crucial for obtaining reliable and repeatable reaction results. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

A condenser 10 is installed inside the reaction chamber 18, and a condenser fan 11 is symmetrically installed on the condenser 10.

[0019] Example 2 like Figures 5-6As shown, the reaction assembly also includes a support plate 43 installed inside the reaction chamber 18. A second support seat 42 is symmetrically fixedly installed on the support plate 43. The second support seat 42 is fixedly connected to the glass reaction plate 2 and the water-cooled pressure plate 200. A first support seat 41 is fixedly installed on the support plate 43. The first support seat 41 is fixedly connected to the clamping seat 40. The glass clamping plate 4 is fixedly connected to the clamping seat 40.

[0020] The top of the glass reaction plate 2 is provided with a first feed port 5 and a second feed port 6. The water-cooled pressure plate 200 is provided with a water inlet 7 and a water outlet 8 on the side away from the clamping seat 40.

[0021] A condenser 10 is installed inside the reaction chamber 18. A condenser fan 11 is symmetrically installed on the condenser 10. A water-cooled outlet 17 connected to the water inlet 7 and a water-cooled inlet 16 connected to the water outlet 8 are installed through the condenser 10.

[0022] A compressor 12 and a circulating pump 13 are symmetrically installed on the inner side of the reaction chamber 18.

[0023] Water-cooled radiators 20 are symmetrically installed on the inner side of the reaction chamber 18, and water-cooled fans 21 are symmetrically installed on the water-cooled radiators 20.

[0024] A plate heat exchanger 14 and a liquid injection solenoid valve 15 are installed on the inside of the reaction chamber 18.

[0025] Adjustment knobs 19 are symmetrically installed on the reaction chamber 18. A first safety valve 22 connected to the first feed port 5 and a second safety valve 23 connected to the second feed port 6 are installed on the reaction chamber 18. A pressure gauge 24 is installed on the reaction chamber 18.

[0026] Based on Embodiment 1, in this embodiment, an external water tank is required for use. The water tank is equipped with a heating rod. First, water or antifreeze is added to the water tank through the water inlet. Then, the main power is turned on, and the system control on the display screen is activated. The hot water in the water tank begins to circulate, and the required reaction temperature is set. A first temperature sensor is installed inside the water tank to detect the temperature inside the tank. A second temperature sensor is installed inside the glass reaction plate 2 to detect the temperature environment required for the reaction. A third temperature sensor is installed on each of the two LED light panels 1. The temperature of the LED light panels 1 is detected and dynamically adjusted through a PID control algorithm.

[0027] Furthermore, after setting the required reaction temperature, the condenser 10 can be turned on via the display screen. A small pump is installed inside the condenser 10 for condensate circulation. Condensation fans 11 are symmetrically installed on the condenser 10. A water-cooled outlet 17 connected to the inlet 7 and a water-cooled inlet 16 connected to the outlet 8 are installed through the condenser 10. The condensate enters the water-cooled pressure plate 200 from the water-cooled outlet 17 on the condenser 10 through the inlet 7, and then enters the water-cooled inlet 16 from the outlet 8. After water cooling, the LED light panel 1 is prevented from overheating. Then, the wavelength of the light panel to be used is selected by adjusting the knob 19, and the light intensity is adjusted.

[0028] Furthermore, the top of the glass reaction plate 2 is provided with a first feed port 5 and a second feed port 6. The water-cooled pressure plate 200 is provided with a water inlet 7 and a water outlet 8 on the side away from the clamping seat 40. The side of the glass clamping plate 4 is provided with a discharge port 9 that communicates with the glass reaction plate 2.

The heating water inlet 25 and the heating water outlet 26 are used to provide a temperature environment for the reaction of the glass reaction plate 2.

[0029] Furthermore, a three-way liquid delivery pipeline is connected between the two first feed ports 5 and the first safety valve 22, and a three-way liquid delivery pipeline is also connected between the two second feed ports 6 and the second safety valve 23. The prepared reaction solution is simultaneously introduced into the glass reaction plate 2 from the first feed port 5 and the second feed port 6 at the required flow rate using a metering pump.

[0030] Furthermore, the pressure changes in the pipeline can be clearly observed as the reaction solution passes through pressure gauge 24 and the first and second safety valves. When the pressure exceeds the safety valve pressure, the pressure will be released to prevent the glass reaction plate 2 from breaking due to overpressure caused by pipeline blockage.

[0031] Furthermore, the reaction solution in the glass reaction plate 2 is then irradiated by the ultraviolet light from the LED light panel 1, and a catalytic reaction takes place in the glass reaction plate 2. After the reaction is completed, the product flows out from the outlet 9.

[0032] Furthermore, the hot water in the water tank is controlled at high and low temperatures by the compressor 12, the circulating pump 13, the condenser 10, the plate heat exchanger 14, and the heating rod in the water tank to ensure the temperature environment required for the reaction in the glass reaction plate 2.

[0033] Furthermore, this design has a built-in controller that can accurately control the reaction temperature of the glass reaction plate 2. For example, when the reaction temperature is too high, the controller controls the small pump in the condenser 10 to accelerate the water circulation, accelerate the rotation of the condenser fan 11 to accelerate heat dissipation, and at the same time slow down the pumping speed of the circulation pump 13. The heating rod in the water tank stops heating. When the reaction temperature is low, the opposite operation is performed.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
