Description

Technical Field

[0002] Photochemical reactions are a class of chemical reactions initiated or promoted by light energy, and are widely used in chemical synthesis, environmental remediation, and energy conversion. Traditional photochemical reaction equipment typically includes a light source, a reactor, and necessary auxiliary facilities. However, existing photochemical reaction equipment has some design limitations that affect reaction efficiency and product quality.

The reactor's internal space is a single unit, with internal light illuminating all materials, resulting in significant variations in light intensity. Furthermore, the circulation of materials within the reactor is often insufficient, causing reactant stagnation and byproduct accumulation. Moreover, the assembly and disassembly processes of traditional equipment are complex, hindering cleaning and maintenance, thus limiting its application in continuous production. To address these technical problems, this application provides a photosensitive oxidation reaction device. Utility Model Content
