AI Technical Summary
Existing chemical waste gas purification devices cannot react with nitrogen compounds at high temperatures, resulting in incomplete waste gas purification.
The design incorporates a multi-layered adsorption filter structure, including a high-temperature filter box and a normal-temperature filter box. The high-temperature filter box contains a filter screen, a reduction layer, and a catalytic oxidation layer, while the normal-temperature filter box contains a catalytic decomposition layer, an oxidation layer, and an activated carbon adsorption layer, which are used to treat pollutants at different temperatures.
It achieves comprehensive purification of chemical waste gas, ensuring that pollutants are completely removed after each reaction layer, and preventing air pollution from being emitted.
