Embodiment
[0045] A photocatalytic membrane reactor, refer to figure 1 , figure 2 , including a reaction kettle 1, which is provided with a reaction chamber 11 inside, the reaction kettle 1 is provided with a liquid inlet 12, a liquid outlet 13 and a light-transmitting area 14, and the reaction chamber 11 is provided with a photocatalytic Film 2, the photocatalytic film 2 is arranged between the liquid inlet 12 and the liquid outlet 13; the liquid enters the reaction chamber 11 through the liquid inlet 12, passes through and contacts the photocatalytic film 2, and the light passes through the light transmission area 14. The photocatalytic film 2 is irradiated, and the liquid is discharged to the outside of the reaction kettle 1 through the liquid outlet 13; the bottom of the reaction chamber 11 is provided with a liquid homogenization groove 3, so that after the liquid is in contact with the photocatalytic film 2, it passes through the liquid homogenization groove. The tank 3 converges...

The invention relates to a photocatalytic membrane reactor, and relates to the technical field of photocatalytic equipment, the photocatalytic membrane reactor comprises a reaction kettle, a reaction cavity is arranged in the reaction kettle, the reaction kettle is provided with a liquid inlet, a liquid outlet and a light transmission area, a photocatalytic membrane is arranged in the reaction cavity, and the photocatalytic membrane is arranged between the liquid inlet and the liquid outlet; a liquid uniformizing groove is formed in the bottom of the reaction cavity, so that the liquid is converged to the liquid outlet through the liquid uniformizing groove after being in contact with the photocatalytic membrane. The top of the liquid homogenizing groove plays a role in supporting the photocatalytic film, so that the photocatalytic film is not easy to damage in the use process, the damage rate of the photocatalytic film in the use process is reduced, the influence on photocatalytic reaction is reduced, and the service life is prolonged; liquid, on the other side of the photocatalytic film, of the liquid homogenizing groove passes through the photocatalytic film, flows and gathers in the groove, and is discharged from a liquid outlet; the influence on the flow of liquid passing through the photocatalytic membrane after the photocatalytic membrane is supported is reduced, and the influence on the efficiency of the photocatalytic membrane is reduced.
Description
technical field [0001] The present application relates to the technical field of photocatalytic equipment, in particular to a photocatalytic membrane reactor. Background technique [0002] Since the discovery of photocatalysts in 1967, photocatalytic reactions have been gradually applied to all aspects of people's lives. At present, photocatalytic reactions are mainly carried out in photocatalytic reactors; in order to increase the contact area between photocatalysts and liquids to increase the reaction speed, the photocatalysts are evenly distributed. On the photoreactive film, the thinner the film thickness, the higher the efficiency of the photocatalyst, so the thickness of the photoreactive film is often set very thin. [0003] In view of the above-mentioned related technologies, the thinner photoreactive film is easily damaged, especially in the liquid phase reaction, the damaged photoreactive film will be folded, reducing the efficiency of the photocatalyst, and the fo...
