Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chemical reactors, in particular to an oscillating flow photocatalytic reactor and equipment thereof. Background Art
[0002] A photocatalytic reactor is a device that uses a light source of a specific wavelength to illuminate a catalyst to achieve a chemical reaction. The catalyst is a substance that can accelerate a chemical reaction, and the light source of a specific wavelength can provide energy to the catalyst to enable it to catalyze.
[0003] In a photocatalytic reactor, an energy balance needs to be established between the light source and the catalyst so that the catalyst can absorb enough light energy and convert it into chemical energy. When a light source of a specific wavelength shines on the catalyst, the photon energy excites the electrons in the catalyst, causing them to break away from atoms or molecules. When these excited electrons fall back to a low energy level, they react chemically with other atoms or molecules, thereby achieving catalysis.
[0004] Currently, photocatalytic reactors are widely used in the chemical industry, but there is still a problem with light utilization. Utility Model Content
