Description

Technical Field

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

[0002] Photocatalysis is a process in which light energy is converted into chemical energy and promoted by exciting reactant molecules or exciting the catalyst to form a complex with reactant molecules under light irradiation, thus promoting the reaction. Currently, the mainstream photocatalytic reaction device, as disclosed in CN117282472B, is a method and equipment for aging catalytic cracking catalysts. This requires light emitted from a light source to pass through a transparent cover into a tubular furnace. To avoid corrosion, the furnace body is usually made of glass. However, glass furnace bodies not only have limited strength and are easily broken, but their large volume also makes transportation and installation difficult, hindering the increase in production capacity.

[0011] Furthermore, the sidewalls of the reaction chamber are coated with an anti-corrosion coating.

[0012] Furthermore, the metal reactor is equipped with an inlet pipe, an outlet pipe, a liquid inlet pipe, and a liquid outlet pipe, which are respectively connected to the reaction chamber.

[0013] Furthermore, the aforementioned photocatalytic reactor also includes a stirrer, which comprises a motor and a stirring shaft. The motor is located outside the metal reactor, and the stirring shaft extends into the reaction chamber.

[0014] The beneficial effects of this utility model are as follows: the lamp plate is placed in a glass tube to form a light source, and the light source is placed in the reaction chamber of the metal reactor. The glass tube isolates the reactants in the reaction chamber from corroding the lamp plate, thereby realizing light radiation inside the furnace.

[0016] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0017] Please refer to Figure 1 or Figure 2 As shown, the present invention provides a photocatalytic reactor, comprising a metal reactor 1 and a light source 2; the light source 2 comprises a glass tube 21 and a lamp plate 22; the body of the glass tube 21 extends into the reaction chamber 11 of the metal reactor 1, the inner cavity of the glass tube 21 is isolated from the reaction chamber 11, and the lamp plate 22 is disposed in the inner cavity of the glass tube 21.

[0018] Working principle: The lamp plate 22 is placed in the glass tube 21 to form the light source 2, and the light source 2 is placed in the reaction chamber of the metal reactor 1. The glass tube 21 isolates the reactants in the reaction chamber 11 from corroding the lamp plate 22, thereby realizing light radiation inside the furnace. Thus, it is no longer necessary to use a glass reactor for photocatalytic reaction, and the reactor can be made of a metal material with better strength.

[0019] It is worth noting that the metal reactor 1 is made of metals with good chemical stability and corrosion resistance, such as titanium alloy, stainless steel, and nickel-based alloy. Of course, to further prevent corrosion, the sidewalls of the reaction chamber 11 can be coated with PVDF (polyvinylidene fluoride), PTFE (polytetrafluoroethylene), or ETFE (ethylene-tetrafluoroethylene copolymer) coatings, which have anti-corrosion capabilities, to improve the service life of the metal reactor 1.

[0020] Among them, the glass tube 21 is preferably made of quartz glass.

[0021] In one embodiment, the glass tube 21 has only one opening for the lamp plate 22 to be placed into the inner cavity of the glass tube 21. The side wall of the end of the glass tube 21 with the opening is provided with external threads, and the metal reactor 1 is provided with a threaded hole that is threadedly connected to the glass tube 21. A sealing ring is provided between the metal reactor 1 and the glass tube 21 to isolate the inner cavity of the glass tube 21 from the reaction chamber 11.

[0022] In another embodiment, the glass tube 21 has only one opening for the lamp plate 22 to be placed into the inner cavity of the glass tube 21. The end of the glass tube 21 with the opening is glued to the metal reactor 1 to isolate the inner cavity of the glass tube 21 from the reaction chamber 11.

[0023] In some embodiments, the lamp panel 22 is equipped with LEDs of various colors. Depending on the light requirements of different photocatalytic applications, appropriate LEDs are used for light emission, providing flexibility in application. Specifically, the lamp panel 22 is equipped with ultraviolet LEDs and white LEDs.

[0024] In one embodiment of cooling the reaction chamber 11, please refer to... Figure 1 As shown, the metal reactor 1 has a heat exchange coil 12 inside the reaction chamber 11. The metal reactor 1 is equipped with an inlet pipe 14 and an outlet pipe 15, which are connected to the inlet and outlet ends of the heat exchange coil 12, respectively. Cold water is injected into the heat exchange coil 12 through the inlet pipe 14 for heat exchange, and hot water in the heat exchange coil 12 flows out through the outlet pipe 15 to control the temperature in the reaction chamber 11, thereby ensuring the performance of the catalyst and the normal operation of the lamp plate 22.

[0025] It is worth noting that the heat exchange coil 12 can be made of glass to prevent corrosion of the reactants in the reaction chamber 11. Quartz glass is the preferred material for the heat exchange coil 12. The heat exchange coil 12 can also be made of chemically stable and corrosion-resistant metals such as titanium alloy, stainless steel, or nickel-based alloy. Furthermore, an anti-corrosion coating can be applied to the surface of the heat exchange coil 12 to further prevent corrosion. This coating can be made of corrosion-resistant materials such as PVDF (polyvinylidene fluoride), PTFE (polytetrafluoroethylene), or ETFE (ethylene-tetrafluoroethylene copolymer).

[0026] In another embodiment of cooling the reaction chamber 11, please refer to Figure 2 As shown, the metal reactor 1 has a cooling chamber 13 surrounding the reaction chamber 11. The metal reactor 1 is provided with an inlet pipe 14 and an outlet pipe 15 respectively connected to the cooling chamber 13. Cold water is injected into the cooling chamber 13 through the inlet pipe 14 for heat exchange, and hot water in the cooling chamber 13 flows out through the outlet pipe 15 to control the temperature in the reaction chamber 11, thereby ensuring the performance of the catalyst and the normal operation of the lamp panel 22.

[0027] In some implementations, please refer to Figure 1 or Figure 2 As shown, the metal reactor 1 is equipped with an inlet pipe 16, an outlet pipe 17, a liquid inlet pipe 18, and a liquid outlet pipe 19, which are respectively connected to the reaction chamber 11. Gas enters and exits the reaction chamber 11 through the inlet pipe 16 and the outlet pipe 17, and liquid enters and exits the reaction chamber 11 through the liquid inlet pipe 18 and the liquid outlet pipe 19.

[0028] It is worth noting that the air inlet pipe 16, air outlet pipe 17, liquid inlet pipe 18, and liquid outlet pipe 19 are all equipped with solenoid valves for controlling the gas-liquid transport.

[0029] In some implementations, please refer to Figure 1 or Figure 2 As shown, the aforementioned photocatalytic reactor also includes a stirrer 3, which comprises a motor 31 and a stirring shaft 32. The motor 31 is located outside the metal reactor 1, and the stirring shaft 32 extends into the reaction chamber 11. During the photocatalytic reaction, the motor 31 can be used to drive the stirring shaft 32 to stir within the reaction chamber 11.
