Abstract:
1. A decontamination system for decontaminating an enclosure defining a region, the decontamination system comprising: a dryer; a dryer conduit, said dryer disposed in said dryer conduit, wherein said dryer conduit has an input side upstream of said dryer and an output side downstream of said dryer; a supply conduit connected at one end to the output side of said dryer conduit and at another end to said region defined by the enclosure; a vaporizer disposed in said supply conduit for vaporizing a liquid decontaminant to produce vaporized decontaminant; a secondary supply conduit connected at one end to the output side of said dryer conduit and at another end to said supply conduit downstream of said vaporizer disposed therein; a return conduit connected at one end to said region and at another end to the input side of said dryer conduit; a bypass inlet conduit connected at one end to the input side of said dryer conduit and said return conduit and fluidly communicating with atmospheric air at another end; a bypass outlet conduit connected at one end to the outlet side of said dryer and to said secondary supply conduit and fluidly communicating with atmospheric air at another end; a first valve disposed in said bypass inlet conduit, said first valve moveable between a first position and a second position, wherein said input side of said dryer conduit is in fluid communication with atmospheric air and said return conduit when the first valve is in the first position and said input side of said dryer conduit is not in fluid communication with atmospheric air when the first valve is in the second position; a second valve disposed at an intersection of said dryer conduit, said secondary supply conduit and said bypass outlet conduit, said second valve moveable between a first position and a second position, wherein said output side of said dryer conduit is in fluid communication with atmospheric air and not in fluid communication with said secondary supply conduit, when said second valve is in the first position, and said output side of said dryer conduit is in fluid communication with said secondary supply conduit and not in fluid communication with the atmospheric air, when said second valve is in the second position; and control means for controlling operation of said first and second valves.
