Description

Technical Field

[0001] This utility model relates to the technical field of photocatalytic reactors, and in particular to a photocatalytic reactor for pharmaceutical intermediates. Background Technology

[0002] Photocatalysis, as an important means of green chemical synthesis, has shown broad application prospects in fields such as pharmaceutical intermediates and fine chemicals. The photocatalytic reactor is the core equipment of this technology, and its core objective is to achieve efficient and uniform transfer of photon energy within the reaction system.

[0003] In the prior art, Chinese utility model patent CN210787314U discloses a photocatalytic reactor, including a reactor body, a sealing cover, a stirring shaft, a stirring paddle, and a drive mechanism. The sealing cover is sealed on the top of the reactor body, and a fixed seat is installed at the center of the top of the sealing cover. The stirring shaft is rotatably mounted on the sealing cover via the fixed seat. One end of the stirring shaft located at the top of the sealing cover is connected to the drive mechanism. The interior of the stirring shaft is a cavity with an open top, and a first lamp group is installed in the cavity. Several through holes communicating with the cavity are opened on the side wall of the stirring shaft, and a first lens is embedded in the sealed interior of each through hole. However, in actual industrial applications, especially in large-scale, continuous production scenarios, the following inherent defects have been exposed: Complex structure and difficult maintenance: This design integrates all precision electrical components such as lamps and power supply brushes into a narrow cavity in the stirring shaft, requiring extremely high assembly standards. If the lamps (light source) malfunction, the entire stirring transmission system (including the sealing cover, drive mechanism, etc.) must be stopped and disassembled for replacement or repair, resulting in long maintenance cycles, high costs, and serious disruption to production continuity.

[0004] Poor heat dissipation performance affects lifespan: The internal space of the stirring shaft is sealed, with poor air circulation, making it difficult to dissipate the large amount of heat generated by the light source during operation. Long-term high-temperature working environment will significantly accelerate the light decay of the light source, shorten its lifespan, and may cause safety hazards due to overheating. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a photocatalytic reactor for pharmaceutical intermediates.

[0006] This utility model discloses a photocatalytic reactor for pharmaceutical intermediates, comprising a reactor body, a feed pipe, a discharge pipe, and a discharge valve.

Multiple sets of fixed seats are provided on the outer wall of the reactor body, and a set of legs is provided at the bottom of each set of fixed seats.

The cooling component cools the material inside the reactor body for the photocatalytic reaction and cools the light-emitting component at the same time. Since the light-emitting component is installed between the reactor body and the cooling component, the convenience of installation, disassembly and maintenance is improved.
