Method and apparatus for removing fumigation gases from fumigated structures

摘要

An apparatus for removing fumigation gasses from fumigated structures is provided. Air is directed from a structure through an adsorption unit and then recirculated back into the structure. A fan directs air through the adsorption unit. The adsorption unit contains an annularly shaped adsorption bed and an inner passage way and outer passage way through which fumigation gasses are directed. A lower adsorption efficiency per pass through the adsorption bed is used in conjunction with multiple passes with the method of the present invention.
