In the above structure, the cabinet 1 is provided with an upper space 2 and a lower space 3, and the air inlet fan 7, the upper space 2 and the exhaust fan 8 sequentially form an air flow path. When the VUV lamp assembly 6 is working, the air entering the upper space 2 can be sterilized by ultraviolet light. Since the emission end of the microwave generator 5 is facing the partition 4, the microwave generator 5 can radiate microwave energy to the air in the upper space 2 when working. In the microwave field, microwaves are used to make the waste gas molecules oscillate, collide and rub at high frequencies, giving extremely high energy to the chemical bond electron pairs, and converting the microwave energy into gas. The internal energy of the molecules in the body is used to excite and ionize them, and at the same time, the electrodeless lamp is stimulated to emit 185nm deep ultraviolet light with a photon energy of 646.4kj/mol. While directly cracking the pollutant components, the photons also stimulate the air to produce active groups such as oxygen free radicals and hydroxyls. Coupled with the synergistic effect of microwave energy, formaldehyde, VOCs and odors are cracked in a very short time. Compared with the existing technology, the present invention can effectively decompose the pollutant molecules in the air, and there is no need to frequently replace components and perform repair and maintenance work. It is suitable for long-term use in laboratory environments and better meets application requirements.
