Description

Technical Field

[0001] The utility model relates to the technical field of photocatalytic reaction, in particular to a photocatalytic reactor for turbid solution. Background Technique

[0002] Photocatalysis was discovered by Professor Akira Fujishima in an experiment in 1967. In the experiment, a titanium oxide single crystal placed in water was irradiated with an ultraviolet lamp, and it was found that water decomposed into oxygen and hydrogen. At present, through long-term technological development, photocatalytic technology has been widely applied in the fields of environmental protection, energy conversion, and material synthesis. For example, in the field of environmental protection, photocatalytic reactions can be used to treat organic wastewater, degrade toxic and harmful substances, etc.; in the field of energy conversion, photocatalytic reaction instruments can be used for hydrogen production by photocatalytic water splitting, solar cells, etc.; in the field of material synthesis, photocatalytic reaction instruments can be used to prepare nanomaterials, photocatalysts, etc.

[0003] A photocatalytic reactor is a necessary catalytic reaction container for containing catalytic reactants and carrying out reactions. At present, when carrying out photocatalytic reactions on some turbid solutions such as organic wastewater, due to the relatively large diameter of the reactor and the low light transmittance of the liquid, external light sources or internal light sources cannot penetrate the reaction solution, which has a certain impact on the reaction efficiency. Therefore, we propose a photocatalytic reactor for turbid solution. Content of the Utility Model

[0004] The purpose of the utility model is to provide a photocatalytic reactor for turbid solution to solve the problems put forward in the above background technique.

[0005] A photocatalytic reactor for turbid solution includes a spray tank and a reaction tank arranged from top to bottom. A first inner groove is provided at the bottom of the spray tank. A first lamp board is arranged at the lower end of the spray tank, and a lamp group is arranged on the first lamp board. The lamp group at the upper end of the first lamp board is inserted into the first inner groove. A nozzle is inserted into the upper end of the spray tank. The lower end of the spray tank is communicated with the reaction tank, and the solution in the spray tank can flow into the reaction tank. A plurality of second inner grooves are provided at the bottom of the reaction tank. The second inner grooves are long cylindrical. A second lamp board is arranged at the lower end of the reaction tank, and a plurality of lamp tubes on the second lamp board are inserted into the second inner grooves. A second conduit is installed on the side of the bottom of the reaction tank, and a switching valve is arranged on the second conduit.

[0006] Preferably, a first conduit is installed at the lower end of the spray tank. The first conduit passes through a through hole opened on the first lamp board and then is inserted into the upper end of the reaction tank. The number of the first conduits is two. The first conduits not only facilitate the liquid in the spray tank to flow into the reaction tank, but also can fix the connection between the spray tank and the reaction tank.

[0007] Preferably, a liquid injection pipe is installed at the upper end of the spray tank, and a pipe cap is provided on the liquid injection pipe, which is convenient for injecting liquids such as catalysts into the spray tank.

[0008] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0009] During the catalytic reaction, the spray head on the spray tank, the second conduit at the lower end of the reaction tank, and the input and output ends of an external liquid pump are connected, enabling the reaction solution to circulate; during the reaction, the reaction solution is sprayed into the bottom of the spray tank through the spray head, and the light emitted by the first light plate at the lower end of the spray tank shines on the sprayed liquid for photocatalytic reaction; the liquid in the spray tank flows into the reaction tank, and the lamp tubes on the second light plates inserted into several second inner grooves of the reaction tank can enable the turbid reaction solution to fully contact with the light, effectively improving the reaction efficiency; and since the first light plate and the second light plate are detachable, different light sources can be replaced as needed.
