[0002] A gas-phase catalytic reactor is a device that catalyzes gaseous reactants using a catalyst, ensuring the reactants remain in a gaseous state. Existing gas-phase catalytic reactors typically use electric heating, which results in unstable temperature control, incomplete reactions, and catalyst waste as the catalyst tends to leave the reactor along with the products.

[0007] The conductor is made of titanium.
[0008] The reactor is made of quartz glass.

[0010] The temperature control device is a coil, and the heat-insulating liquid circulates inside the coil.

[0020] 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.
[0021] Please refer to Figures 1-3 A gas-phase catalytic reactor includes a reactor, with temperature control devices installed at both the upper and lower parts of the reactor, and a conductive material installed on the inner wall of the reactor.
[0022] As can be seen from the above description, the beneficial effects of this utility model are as follows: The gas-phase catalytic reactor of this utility model is provided with two opposing temperature control devices in the depth direction of the reactor. The temperature control device located at the lower part can ensure that the material and catalyst can carry out catalytic reaction within a specified temperature range, and ensure that the catalyst can always remain in a gaseous state, thereby increasing the contact area with the material during reaction and achieving a full reaction. When the mixed gas flows to the temperature control device located at the upper part, the temperature control device can condense the gaseous catalyst into a liquid state without changing the products and some unreacted materials, thereby realizing the recovery of the catalyst and avoiding waste of the catalyst.
[0023] Furthermore, conductive materials are installed on the inner wall of the reactor.
[0024] As can be seen from the above description, gas flow may generate static electricity. Installing a conductor on the inner wall of the reactor can both conduct static electricity and not affect ultraviolet irradiation.
[0025] Furthermore, the conductor is connected to the wire.
[0026] As can be seen from the above description, connecting a conductive body to a wire can accelerate the discharge of static electricity.
[0027] Furthermore, the end of the wire furthest from the conductor is located outside the reactor.
[0028] Furthermore, the conductor is made of titanium.
[0029] As can be seen from the above description, titanium has ideal electrical conductivity and antistatic properties.
[0030] Furthermore, the reactor is made of quartz glass.
[0031] As described above, when the catalyst is a photocatalyst such as bromine, it tends to condense on the inner wall of the reactor. Therefore, quartz glass is chosen to make the reactor. Quartz glass is pressure-resistant and has no loss to ultraviolet light, thus allowing for the formation of higher temperatures and preventing condensation.
[0032] Furthermore, the reactor is equipped with a feed inlet and a discharge outlet.
[0033] Furthermore, the temperature control device is a coil, within which the insulating liquid circulates.
[0034] Insulating liquids such as water, ethanol solutions, and common substances used in insulating oil lamps.
[0035] Furthermore, the coil located at the top of the reactor carries a low-temperature liquid, while the coil located at the bottom of the reactor carries a high-temperature liquid.
[0036] Furthermore, the temperature of the insulating liquid in the coil located at the top of the reactor is lower than the boiling point of the catalyst, while the temperature of the insulating liquid in the coil located at the bottom of the reactor is higher than the boiling point of the catalyst.
[0037] As can be seen from the above description, the insulating liquid inside the coil ensures the reaction can proceed.
[0038] Furthermore, there are at least two reactors, which are interconnected.
[0039] As can be seen from the above description, increasing the number of reactors can improve the degree of reaction completion.
[0040] Furthermore, the upper part of the previous reactor is connected to the lower part of the next reactor.
[0041] Furthermore, a catalyst supply port is provided on the reactor.
[0042] As can be seen from the above description, adding a catalyst supply port is necessary to achieve a continuous reaction.
[0043] Please refer to Figures 1-3Embodiment 1 of this utility model is as follows: A gas-phase catalytic reactor 1 includes a reactor 1 made of quartz glass and a coil 2 disposed in the reactor 1. The upper and lower parts of the reactor 1 are both provided with coils 2. There are three reactors 1, which are connected to each other in sequence through pipes 5. The upper part of the first reactor is connected to the lower part of the next reactor. The temperature of the insulating liquid in the coil 2 of the first two reactors 1 is higher than the boiling point of the catalyst. In the last reactor 1, the temperature of the insulating liquid in the coil 2 located at the upper part of the reactor 1 is lower than the boiling point of the catalyst, and the temperature of the insulating liquid in the coil 2 located at the lower part of the reactor 1 is higher than the boiling point of the catalyst. The lower part of the first reactor 1 is provided with an inlet 11, and the upper part of the third reactor 1 is provided with an outlet 12. A titanium conductive body 3 is provided on the inner wall of the reactor 1. The titanium conductive body 3 is connected to a wire 4. The end of the wire 4 away from the titanium conductive body 3 is located outside the reactor 1. The insulating liquid circulates in the coil 2.
[0044] The principle of Embodiment 1 of this utility model is as follows: gaseous materials and catalysts enter reactor 1 through inlet 11. Under the action of the coils 2 of the first two reactors 1 and the coil 2 located at the bottom of the last reactor 1, the gaseous state is maintained and the reaction takes place at a specified temperature. When the reaction gas rises to the upper coil 2 of the last reactor 1, the gaseous products and residual reactants are discharged from outlet 12. The gaseous catalyst condenses into liquid and flows back to the bottom along the inner wall of reactor 1 to complete the recovery. During this reflux process, the titanium conductive body 3 can complete the electrostatic discharge, avoiding the formation of liquid droplets on the inner wall of reactor 1 and reducing the risk of electrostatic accumulation and release.
[0045] Embodiment two of this utility model is as follows:
[0046] The difference between Example 2 and Example 1 is only that: only one reactor 1 is provided, with a feed inlet 11 at the bottom and a discharge outlet 12 at the top.
[0047] The principle of Embodiment 2 of this utility model is as follows: gaseous materials and catalysts enter reactor 1 through inlet 11. Under the action of the lower coil 2, they are always kept in a gaseous state and react at a specified temperature. When the reaction gas rises to the upper coil 2, the gaseous products and residual reactants are discharged from outlet 12. The gaseous catalyst condenses into liquid and flows back to the bottom along the inner wall of reactor 1 to complete the recovery. During this reflux process, the titanium conductive body 3 can complete the electrostatic discharge, avoiding the formation of liquid droplets on the inner wall of reactor 1 and reducing the risk of electrostatic accumulation and release.
[0048] Embodiment three of this utility model is as follows:
[0049] The only difference between Example 3 and Example 1 is that a catalyst supply port is provided on reactor 1.
[0050] In summary, the gas-phase catalytic reactor provided by this invention has the following advantages:
[0051] 1. The reaction is ensured by setting a temperature control device at the bottom of the reactor, and the catalyst is kept in a gaseous state during the reaction to ensure a complete reaction.
[0052] 2. A temperature control device is installed at the top of the reactor to complete the recovery of the catalyst.
[0053] 3. Install a conductive body on the inner wall of the reactor to conduct static electricity, thereby reducing the risk of static electricity accumulation and release.

Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
