A gas purifying system includes a water spraying system, and a collecting apparatus installed downstream of the water spraying system. The collecting apparatus has a surface composed of an electron emitting material, and the electron emitting material is capable of emitting electrons when subjected to visible light, ultraviolet light or electrical energy. The system can also include an ultraviolet lamp, with an ultraviolet photoelectron emitting material surrounding the ultraviolet lamp. The ultraviolet lamp and the ultraviolet photoelectron emitting material are positioned between the water spraying system and the collecting apparatus. |
