AI Technical Summary

Technical Problem

Existing photochemical reactors suffer from problems such as low light energy utilization, easy contamination and blockage, difficulty in gas-liquid exchange and heat dissipation, complex structure and high cost due to their reliance on solid reaction channel walls.

Method used

A self-constructed flow channel photochemical reactor is adopted. A liquid column that flows continuously along a preset path is formed in the reaction chamber. The space between the liquid column and the inner wall of the reaction chamber is filled with a gaseous medium. The light beam undergoes total reflection at the interface between the liquid column and the gaseous medium, eliminating contact with the solid wall. The liquid column generation device and the product collection device are respectively located at both ends of the reaction chamber.

Benefits of technology

It achieves high light energy utilization, avoids solid wall contamination and clogging, improves gas-liquid mass transfer efficiency and heat dissipation performance, and has a simple structure and strong adaptability.
