Abstract
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.
Claims13
A gas purifying system for removing molecular contaminants from the air in a room, said system comprising:
- a water spraying apparatus that sprays water droplets into incoming air to be purified;
- and
- a collecting apparatus disposed downstream of said water spraying apparatus in the direction of air flow through the system, said collecting apparatus comprising a plurality of planar collecting plates spaced from one another in the direction of air flow through the system, each of said collecting plates comprising electron emitting material that emits electrons, and each of said collecting plates having a plurality of openings therethrough, and intersection points at which the electron emitting material exists between adjacent ones of the openings, said collecting plates being disposed in an offset positional relationship relative to each other wherein the intersection points of an upstream collecting plate confront the openings in a collecting plate disposed downstream thereof in the direction of air flow through the system.
