Problems solved by technology

[0004] At present, there are many liquid-solid phase photocatalytic reactors that apply fluidization process in photocatalytic reaction equipment, but the photocatalytic reactors designed by them all use the convective principle of solid-liquid phase in fluidization for photocatalysis. It cannot fully mix the solid-liquid two phases, such as patent No. 201510132687.9, which is named "A Photocatalytic Water Splitting Hydrogen Production Device", which uses tr

Example Embodiment

[0020] Such as figure 1 As shown, the operation process of the device is as follows,

[0021] S1 Close the valve at the bottom of the catalyst sedimentation tank 11, and add the reaction liquid. When the reaction liquid level exceeds the reaction liquid inlet 7, turn on the pump 12. When the reaction liquid in the cylindrical conical reaction tower 3 can flow from the reaction liquid outlet 8 back to the catalyst settling tank 11, stop adding the reaction liquid to realize liquid phase circulation.

[0022] S2 turns on light source 1.

[0023] S3 adds the solid catalyst from the upper part of the cylindrical conical reaction tower 3, and the static mixing of the multi-stage baffle can fully contact the reaction liquid. When the catalyst flows into the catalyst sedimentation tank 11 through the catalyst suspension outlet 10, and is in the catalyst sedimentation tank 11 The bottom settles, open the valve at the bottom of the catalyst settling tank 11, and continue to add a certain am...
