Method and apparatus for sterilizing and disinfecting air and surfaces and protecting a zone from external microbial contamination

摘要

This invention relates to a method, process and apparatus for disinfecting and sterilizing all types of surfaces contaminated with microorganisms and toxic substances to render both inactive. Furthermore, this invention relates to both a method and apparatus for disinfecting and/or sterilizing breathable air and then using this air to protect a confined space from external contamination. The apparatus consists of a new ultra-violet (NUV) source that is more effective than mercury based 254 nm light for destroying DNA of virus, bacteria, spores and cists. It is most effective in breaking chemical bonds in toxic gases and Biotoxins that are useful to terrorists. It is combined with other apparatus that remove particulates and byproducts sometimes produced by the NUV source and maintains positive pressure of the confined space so as to prevent the influx of air from outside the protected zone.

主权项

1. A disinfecting apparatus comprising:
a source of photons having a wavelength that substantially corresponds to an absorption peak of amino acids or proteins in microorganisms, the wavelength being 222 nm, the source of photons producing a quantity of ozone gas; a photon reflector secured in a spaced relationship to the photon source, whereby the apparatus produces photons that are directed to a selected zone or surface; an air duct surrounding the photon source; a particle removal means in the duct secured in a spaced relationship to the photon source; and wherein the particle removal means is an electrostatic precipitator positioned downstream of an air flow from the source of photons, and constructed and arranged to convert the quantity of ozone into oxygen gas.
