VOCs is the abbreviation of volatile organic compounds, which is another focus of waste gas pollution in the world after SO2, NOx and Freon. VOCs refer to volatile hydrocarbons and their derivatives, including hydrocarbons, aromatic hydrocarbons, alcohols, aldehydes, ketones, esters, amines, organic acids, etc. At room temperature, VOCs have a high evaporation rate and are very volatile, which will cause serious harm to the environment. Therefore, a device for monitoring VOCs gas is needed.

After searching Chinese patents (publication number: CN216870499U), a printed VOCs waste gas decomposition monitoring device was disclosed, which solves the problem that the existing VOCs monitoring equipment, after long-term use, has different environmental scenarios, resulting in some harsh usage scenarios. The inlet pipes of the VOCs monitoring equipment need to be manually cleaned and maintained regularly to avoid inaccurate monitoring results. However, the device only has the function of detection and cannot process the waste gas. Therefore, a printed VOCs waste gas decomposition monitoring device is needed to solve the above problems.
