AI Technical Summary

Problems solved by technology

[0002] At present, the technology of purification treatment using photocatalysis is becoming more and more complete. Photocatalysis technology has high safety, low energy consumption, will not cause secondary pollution, and is beneficial to the environment. This technology has already been used in sewage treatment and indoor air purification. The purification effect is very ideal. In the process of photocatalysis, a catalyst is needed to assist in the reaction. The catalyst itself hardly reacts. The catalyst is only used as a medium for transferring energy in the reaction process, so the catalyst can be used forever. Although the catalyst It will not cause serious pollution to the environment, but it has toxic effects on certain species. However, under the existing reaction device, there is a lack of effective recovery and reuse of catalysts, resulting in a certain degree of waste

[0003] According to research statistics, the reaction efficiency of photocatalysis has not been improved. The reasons for the inability to improve efficiency are due to the insufficient mixing of the material to be treated and the catalyst, the low utilization rate of light energy during photocatalysis, and the temperature of the reaction environment. The pressure is not in the saturated catalytic range, etc., so the production efficiency of photocatalysis is almost synchronized with the consumption rate and remains low, which hinders the promotion and popularization of photocatalytic purification treatment
