Problems solved by technology

This patent uses plasma oxidation-activated carbon adsorption to achieve its purification effect on pollutants. The process technology route is relatively complicated, the technology is relatively immature, and there is no mature commercial application. It can only be used as a simulation under laboratory conditions. test system
[0004] At the same time, most of the above-mentioned pollutant evaluation and treatment devices use manual measurement methods, and the technical requirements for measurement personnel are very high, and professional technicians are needed to realize
The test process is time-consuming and laborious, the efficiency is not high, and the measurement repeatability is difficult to guarantee, and the desulfurization and denitrification performance of active coke cannot be accurately characterized. It is a requirement to provide relevant data technical support for the commercial application of activated coke flue gas purification technology
