Abstract

The application discloses a gaseous pollutant photocatalytic online detection apparatus and method, the detection device comprises an air storage tank and a polluted gas tank, the air storage tank is connected directly with a mixing tank through a pipeline and is connected with the mixing tank by another pipeline through a closed container holding water, the polluted gas tank is connected with the mixing tank, the mixing tank is connected with a photocatalytic reactor, and the photocatalytic reactor is connected with a polluted gas detector; the detection method comprises: after being mixed in the mixing tank, air and polluted gas enter and react in the photocatalytic reactor, and reacted gas enters the polluted gas detector to acquire polluted gas concentration, thereby detecting in real time polluted gas concentration in a flow system. The application addresses the problems that photocatalytic degradation offline equipment is unable to simulate a real application environment and manual sampling is long in cycle, low in data quantity, time-consuming and labor-consuming and low in reliability, and it is possible to monitor in real time polluted gas during gaseous photocatalysis.

Description

technical field [0001] The application belongs to the technical field of photocatalytic pollution gas degradation and detection, and specifically relates to a photocatalytic on-line detection device for gaseous pollutants, and also relates to a photocatalytic on-line detection method for gaseous pollutants. Background technique [0002] With the development of photocatalytic technology, the application of photocatalytic materials in the field of environment has attracted more and more attention. The application of photocatalysis in the environmental field is currently the most researched mainly on the pollutants in water and the polluted gases in the air. However, as a new type of environmentally friendly material, the first thing to be solved when it is applied to production practice is to use reliable and effective means to evaluate and test the material performance. At present, the evaluation methods for photocatalytic materials in the environmental field are still very ...
