Description

Technical Field

[0001] The utility model belongs to the field of photocatalytic reaction devices, and in particular relates to a continuous photocatalytic reactor. Background Art

[0002] Photocatalytic reaction is a type of reaction that uses the light energy generated by the light source to convert into the energy required for chemical reaction under the irradiation of light to produce catalytic effect. It is mainly used in the fields of sewage treatment, photocatalytic nitrogen fixation and organic synthesis.

[0003] In recent years, researchers have done a lot of research on the reaction mechanism, catalyst preparation and modification of photocatalysis, but the practical application of photocatalytic technology is still restricted and hindered by the effective design of photocatalytic reactors. The photocatalytic reactors currently used are limited by conditions such as cooling systems or light source irradiation methods, resulting in complex reactor structures and difficult processing, which increases the manufacturing cost of the reactor. For example, patent CN218689354U uses flat glass as the main body of the reactor, and the heat exchange system is inside the glass plate, which increases the difficulty of manufacturing. In addition, due to the difficulty of manufacturing, only glass can be used, which also restricts some photocatalytic reactions, such as the application of low-wavelength ultraviolet. Patent CN215877889U designs a cylindrical photocatalytic reactor, and arranges the light source in the cylinder. Although it is easy to manufacture and process, the heat exchange problem of the system is difficult to solve, and the choice of light source is limited. Utility Model Content
