[0002] A reactor is a device that realizes a chemical or biochemical reaction process and is widely used in the fields of chemical industry, oil refining, metallurgy, light industry, pharmaceuticals, biotechnology, etc. Its main function is to provide a suitable environment for chemical reactions or biological processes, including reaction space, reaction conditions (such as temperature, pressure, stirring, ventilation, etc.) and necessary material transfer mechanisms to promote and control the desired chemical or biological transformation process. Traditionally, a stirred tank reactor is used, but the physical shear force such as stirring will affect the catalyst and also inhibit the product. Therefore, the current reactor generally adopts a packed bed reactor, which uses catalyst particles to fill the container, and the reactant fluid flows into the reactor from one end, and contacts the catalyst particles in the reactor with gas-solid and liquid-solid, and the product fluid flows out from the other end of the reactor. The catalyst particles in the packed column reactor are compactly packed and the catalyst layer is relatively fixed. It is also called a fixed bed reactor. It is a widely used type of reactor, but there is still a situation where the substrate and the product are in contact for a long time, resulting in the generation of impurities. The output yield is low, the scope of application is small, and it cannot be used for large-scale production in factories. Utility Model Content
