Description

Technical Field

[0001] This utility model relates to the field of photocatalysis technology, specifically to a novel double-sided photothermal catalytic reactor. Background Technology

[0002] Gas-solid phase photothermal catalysis is a catalytic chemical reaction carried out in a high-temperature gas phase environment in the presence of a solid catalyst. It is widely used in many important research fields such as carbon dioxide reduction, degradation of gaseous pollutants, nitrogen fixation, and methane oxidation. To meet the comprehensive requirements of light, heating, gas-solid phase contact and airtightness in the reaction process, researchers have developed a variety of tubular reactors. Their core differences are mainly reflected in the light irradiation method and the catalyst loading method.

[0003] Regarding illumination methods, existing reactors are mainly divided into two categories: single-sided illumination and double-sided illumination. Since light energy has limited penetration through the thickness of the catalyst bed, double-sided illumination design allows both sides of the catalyst bed to be illuminated simultaneously, significantly improving light utilization. Therefore, it has become the preferred solution for efficient photothermal catalytic reactions. For example, some double-sided illumination reactors adopt a cross-shaped structure, achieving bidirectional illumination through light-transmitting openings on both sides to improve the light absorption efficiency of the catalyst. However, if the distance between the two light-transmitting openings is too short, the temperature rise from illumination and the high temperature inside the furnace may affect the sealing of the window, which is not conducive to the long-term stable operation of the reaction.

[0004] Therefore, a novel double-sided photothermal catalytic reactor is needed to improve the above problems. Utility Model Content

Detailed Implementation

[0028] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Example 1

[0030] like Figures 1 to 3As shown, a novel double-sided photothermal catalytic reactor according to the first aspect of this utility model includes a main structure, which is T-shaped and mainly consists of an outer tube 1. The outer tube 1 serves as the core support and sealing cavity, and its interior is hollow. At each of the two ends of the T-shape, an irradiation end 3 is fixedly connected, forming a channel for light to enter the reactor. An air inlet end 4 is provided at one end of the main structure, which communicates with the internal cavity of the main structure, allowing the reaction gas to enter the system. The exhaust structure is bolted to the main structure. The lower end is fitted with a symmetrically arranged set of light guide columns 10, with the two light guide columns 10 distributed inside the two ends of the outer tube body 1; the catalyst tank 12, the upper end of which is provided with a flat bearing end, the bearing end is located between the adjacent ends of the two light guide columns 10, the inside of the catalyst tank 12 is hollow, and the bearing end is provided with catalyst; the gas guide pipe 13 is used to connect the catalyst tank 12 and the exhaust structure, and guides the gas generated by the reaction to the exhaust structure for discharge, the gas guide pipe 13 is connected to the bottom of the catalyst tank 12 through a graphite sleeve.

[0031] In the above embodiments, it should be noted that, considering the heat generated during the photothermal catalysis process, in order to ensure the long-term stable operation of the reactor, multiple sets of heat sinks 2 are provided on the tube walls at both ends of the outer tube 1, especially in the area near the irradiation end 3. These heat sinks 2 can effectively increase the heat dissipation area, accelerate heat dissipation, and prevent damage to optical elements or impact on the catalytic reaction due to excessive temperature. On the inner side of the two irradiation ends 3, i.e., inside the outer tube 1, a set of light guide columns 10 are symmetrically arranged. The function of the light guide columns 10 is to conduct and converge the light introduced from the irradiation end 3. Each light guide column 10 has a larger diameter protrusion at the end away from the center, which helps in the reception of light and stable installation.

[0032] The technical effect achieved by the above embodiment is as follows: a window 11 is provided on the outer side of the protrusion. The window 11 not only plays a sealing role to prevent gas leakage, but also protects the internal light guide column 10 from contamination. In order to ensure the sealing of the connection between the window 11 and the irradiation end 3, a sealing ring 15 is embedded in the groove opened inside the window 11.

[0033] The core area where the catalytic reaction occurs is the catalyst tank 12, which is hollow inside and has a flat support end at its upper end. This flat support end is precisely positioned between the adjacent ends of the two light guide columns 10, so that the light emitted from the two light guide columns 10 can evenly and concentratedly illuminate the support end. The catalyst is placed inside the support end. During operation, the reaction gas introduced from the gas inlet 4 flows over the catalyst surface and undergoes a photothermal catalytic reaction under the illumination of the light from both sides and the action of the catalyst.

[0034] Example 2

[0035] like Figures 1 to 3 As shown, a novel double-sided photothermal catalytic reactor includes all the components of Example 1, except that a dedicated flow guiding and exhaust structure is provided for efficient collection of the gaseous products generated in the reaction. At the bottom of the catalyst tank 12, a gas guide pipe 13 is connected via a graphite sleeve. The graphite sleeve has good high-temperature resistance and sealing performance, and can adapt to the working environment inside the reactor. The other end of the gas guide pipe 13 extends downwards and connects to the exhaust structure.

[0036] The technical effect achieved by the above embodiment is as follows: the exhaust structure is tightly connected to the lower docking end 5 at the lower end of the main structure by bolts. The exhaust structure mainly includes a docking column 14, the upper end of which is provided with a docking ring 6 that matches the lower docking end 5 to ensure a stable and sealed connection. The docking column 14 is hollow inside, forming a gas collection cavity. An exhaust component 7 is inserted into the middle of its lower end. The gas generated by the reaction first enters the internal cavity of the docking column 14 through the gas guide pipe 13, and then flows into the exhaust component 7. The exhaust component 7 is also hollow inside, and its side is provided with an outlet protrusion 8 for discharging the final product gas out of the reactor.

[0037] Example 3

[0038] like Figures 1 to 3 As shown, a novel double-sided photothermal catalytic reactor is included in all the contents of Example 1. The difference is that, in order to monitor the reaction temperature, a temperature measuring protrusion 9 is provided at the lower end of the exhaust component 7, which can be used to install a temperature sensor to monitor the temperature of the exhaust gas in real time and provide a reference for controlling the reaction conditions.

[0039] Working principle: The reactant gas enters the outer tube 1 from the inlet end 4 and comes into contact with the catalyst on the supporting end of the catalyst tank 12. At the same time, light emitted from an external light source enters from the irradiation ends 3 on both sides, is conducted and converged by the light guide column 10, and simultaneously irradiates the catalyst from both sides, stimulating the photothermal catalytic reaction. The gaseous products generated by the reaction are discharged through the gas guide pipe 13 at the bottom of the catalyst tank 12, enter the exhaust structure below, and are finally discharged from the gas outlet protrusion 8 on the side of the exhaust component 7. Throughout the process, the double-sided illumination ensures uniform heating and photoexcitation of the catalyst, the flat supporting end increases the illumination area and gas contact area, and the T-shaped structure rationally plans the gas path and light path, making the reactor structure compact and highly efficient.

[0040] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.

[0041] The terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Any changes or adjustments to their relative relationships, without substantially altering the technical content, shall also be considered within the scope of implementation of this utility model.
