Parallel flow VHP decontamination system
First Claim
1. A closed loop vapor decontamination system for decontaminating a defined region, said system comprising:
- a chamber defining a region;
a first fluid flow path connected at both ends to said chamber to define a first closed loop path through said chamber;
a second fluid flow path connected at both ends to said chamber to define a second closed loop path through said chamber;
a means for conveying a carrier gas simultaneously along said first and said second fluid flow paths;
a generator for generating vaporized hydrogen peroxide disposed along said first fluid flow path for introducing vaporized hydrogen peroxide into said carrier gas as it circulates through said first fluid flow path;
a destroyer for converting said vaporized hydrogen peroxide into water and oxygen disposed along said second fluid flow path for breaking down said vaporized hydrogen peroxide in said carrier gas as it circulates through said second fluid flow path; and
a controller controlling the amount of said carrier gas flowing along said first and second fluid flow paths.

Abstract
A closed loop vapor decontamination system for decontaminating a defined region. A chamber defines the region. A first fluid flow path connects at both ends to the chamber to define a closed loop path through the chamber. A second fluid flow path connects at both ends to the chamber to define a closed loop path through the chamber. The system has a means for conveying a carrier gas simultaneously along the first and second fluid flow paths. A generator generates vaporized hydrogen peroxide and is disposed along the first fluid flow path for introducing vaporized hydrogen peroxide into the carrier gas as it circulates through the first fluid flow path. A destroyer converts the vaporized hydrogen peroxide into water and oxygen and is disposed along the second fluid flow path for breaking down the vaporized hydrogen peroxide in the carrier gas as it circulates through the second fluid flow path. A controller operates to control the amount of the carrier gas flowing along the first and second fluid flow paths.

-
providing a decontamination system having a sealable region, a first fluid flow path and a second fluid flow path that both include said sealable region and a sensor disposed within said sealable region operable to monitor the conditions within said sealable region to provide signals indicative of said conditions;
conveying a flow of a carrier gas simultaneously along said first fluid flow path and said second fluid flow path;
introducing vaporized hydrogen peroxide into said carrier gas flowing along said first fluid flow path;
destroying said vaporized hydrogen peroxide in said carrier gas flowing along said second fluid flow path; and
varying the relative flow of carrier gas along said first fluid flow path and said second fluid flow path based on signals from said sensor. drying said carrier gas flowing along said third fluid flow path. - View Dependent Claims (18, 19, 20)
