Chlorine Dioxide Decontamination System and Methods

摘要

A scalable, portable and modular chlorine dioxide fumigant decontamination system having an activating area and a neutralizing area which may be housed separately or as a single operationally connected unit, and which may be configured as a closed loop system connected to a decontamination chamber for decontamination of articles, or as an open loop system for decontamination of interiors and large confined spaces, and employing a specialized activating cup that is permeable to air yet substantially impermeable to water and chlorine dioxide reaction by-products such that directing air through the activation cup releases nearly pure chlorine dioxide fumigant. Methods and articles relating to the system are also described.

主权项

1. A decontamination system comprising:
a chlorine dioxide (ClO2) fumigant activating area, optionally, a by-pass flow area, a neutralizing area; a first variable speed air blower in direct fluid communication with the ClO2 fumigant activating area, the by-pass flow area and the neutralizing area; a valve system for dedicating air flow from the blower to one or more of the areas, wherein the activating area comprises an activation cup configured to receive reagents for in situ generation of ClO2 fumigant, said activation cup being permeable to air and substantially impermeable to water and reaction by-products, further wherein the activation cup is suspended in the activation area such that air flowing from the first variable speed air blower into the activation area flows through and around the activation cup such that generated ClO2 fumigant passes out of the activation cup with the air flow while water and reaction by-products remain in the activation cup.
