The equipment adopts a stainless steel fixed pry mounted fully sealed structure, which is easy to install. The interior is coated with stainless steel special anti-corrosion material, which is resistant to acid, alkali and waste gas environments. The equipment has a long service life and is composed of a pre-treatment section, a coupled reaction device, and an array drawer type module. The high-energy particle field generated by the coupling catalytic network of precious metals is irradiated through the ultraviolet band to the coupling synergy effect of independently prepared precious metals and titanium dioxide nanoparticles. VOCs organic waste gas is decomposed into carbon dioxide, water, etc. Other waste gas molecules that have not been completely degraded can be oxidized into water-soluble small molecules and some active free radicals.
