Technical Field

[0001] The utility model relates to a reactor, in particular to a continuous flow photocatalytic reactor used in the field of experimental equipment. Background Art

[0002] A continuous-flow photocatalytic reactor is a device with significant application value in chemical reactions. It utilizes light energy to excite a catalyst, driving chemical reactions within a continuous flow system. Typically, it consists of a light source, a reaction channel, and a catalyst. The light source provides light of a specific wavelength, which illuminates the reaction channel containing the catalyst to promote the conversion of reactants.

[0003] The specification of Chinese patent CN220968704U discloses a photocatalytic reactor, including a heater, a temperature control box provided on the heater, and a reactor provided in the temperature control box. The photocatalytic reactor of the utility model is provided with a three-layer catalyst loading net, which makes the catalyst spreading more uniform, can achieve the effect of full contact between the solid catalyst and the reaction gas molecules in the entire reactor body, uniform illumination, and improve the reaction efficiency.

[0004] In the field of scientific research, researchers often need to explore and optimize different reaction conditions. However, the height of the light source on a continuous flow photocatalytic reactor cannot be adjusted, making it impossible to systematically study the effects of light intensity and light source distance on the reaction. If an electric device is used to drive the reactor, not only will the cost increase, but the electric device may also generate electromagnetic interference during operation, which may have adverse effects on other electronic devices or sensors in the photocatalytic reactor. Utility Model Content

[0005] In response to the above-mentioned existing technologies, the technical problem to be solved by the present invention is that the height of the light source on the continuous flow photocatalytic reactor cannot be adjusted, so it is impossible to systematically study the effects of light intensity and light source distance on the reaction. If an electric device is used to drive the reactor, not only will the cost increase, but the electric device may also generate electromagnetic interference during operation.

[0006] The top end face of described sliding panel also is provided with an end face that is provided with of sliding panel withstands on the back face, and the bottom end face of described sliding panel withstands on the back face.

[0007] In the above-mentioned continuous flow photocatalytic reactor, the equipment body in this scheme is set on the equipment frame and a lighting lamp is set directly above it to provide a light source to assist the operation of the reactants. When the actual height of the lighting lamp needs to be adjusted, the height of the lighting lamp can be quickly adjusted according to different reaction requirements. The structure is simple and reliable and not prone to failure. The convenient manual adjustment allows the operator to easily change the height of the lighting lamp, reducing energy consumption and lowering operating costs, thereby more efficiently designing and optimizing experiments.

[0008] As a further improvement of the present application, the engaging cylinder and the corresponding relative vertical rod are engaged with each other, and an external convex ball is fixedly connected to the end of the extrusion block away from the square notch.

[0009] As a further improvement of the present application, the inner end of the engaging inner hole is fixedly connected with an anti-skid particle liner, and the anti-skid particle liner cooperates with the outer side wall of the engaging cylinder.

[0010] As a further improvement of the present application, the device body includes a reactor body, and a sapphire window is installed at the upper end of the reactor body.

[0011] As another improvement of the present application, calipers are symmetrically provided on the left and right sides of the reactor body, and a reactor heating furnace is installed on the outside of the reactor body.

[0012] As another improved supplement of the present application, an armored thermocouple is installed at the inner end of the reactor body, and a catalyst bed is provided in the middle of the inner end of the reactor body.

[0013] As another improved supplement of the present application, the upper end of the catalyst bed is filled with catalyst, and an air outlet and an air inlet are respectively provided below the reactor body.

[0014] In summary, in this solution, the equipment body is arranged on the equipment frame and a lighting lamp is arranged at a position directly above it to provide light source to assist the operation of the reactants. When the actual height of the lighting lamp needs to be adjusted, the extrusion block in the square groove is pressed with two fingers to make the internal spring retract, and the linkage cross bar in the extrusion block can move up and down in the lighting lamp. When the height of the adjustment bar is adjusted, the two extrusion blocks are released, and the linkage cross bar outside the two extrusion blocks can rebound forward and backward following the reset path of the spring. After rebounding, the engaging cylinders on both sides of the linkage cross bar can be engaged with the corresponding relative vertical rod outer engaging inner holes. The height of the lighting lamp can be quickly adjusted according to different reaction requirements. The structure is simple and reliable and not prone to failure. The convenient manual adjustment allows the operator to easily change the height of the lighting lamp, reduces energy consumption, reduces operating costs, and thus more efficiently designs and optimizes experiments. At the same time, the outer convex ball can make the pressing process of the extrusion block have a force point, and the operation method is more humane. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0025] The first implementation method:

The adjusting cross bar 2 slides up and down in the side slide groove 13, and the front and rear ends of the side slide groove 13 are symmetrically fixed with relative vertical rods 14. The ends of the two relative vertical rods 14 close to each other are provided with multiple locking inner holes 15, and the multiple locking inner holes 15 are equidistantly arranged from top to bottom. Circular grooves are symmetrically provided on the left side of the front and rear ends of the adjusting cross bar 2, and the locking cylinders 20 pass through the corresponding circular grooves to pass through the outside of the adjusting cross bar 2.

[0027] Figure 1-6 It is shown that the locking cylinder 20 is locked with the corresponding relative vertical rod 14, and the end of the extrusion block 17 away from the square groove 16 is fixedly connected to the outer convex ball 18. The equipment body includes a reactor body 9, a sapphire window 4 is installed on the upper end of the reactor body 9, and calipers 5 are symmetrically arranged on the left and right sides of the reactor body 9. A reactor heating furnace 8 is installed on the outside of the reactor body 9, and an armored thermocouple 10 is installed on the inner end of the reactor body 9. A catalyst bed 7 is provided in the middle of the inner end of the reactor body 9, and the upper end of the catalyst bed 7 is filled with a catalyst 6. An air outlet 12 and an air inlet 11 are respectively provided below the reactor body 9.

[0028] Figure 1-6A continuous flow photocatalytic reactor is shown. In this solution, the device body is correctly installed on the device frame 1 to ensure that all components are tightly connected and leak-free. At the same time, the device body is set on the device frame 1 and a lighting lamp 3 is set directly above it to provide a light source to assist the operation of the reactants. A suitable catalyst 6 is selected and filled into the reactor body 9.
