Abstract

Devices and methods for treating a gas flow are disclosed. The gas treatment device includes a vessel into which a gas riser is passed. A gas chamber is defined within the vessel in communication with the gas riser and a treatment particle bed is extended at least partially about the gas riser. A flow control device in communication with the treatment particle bed and the gas riser is constructed and arranged to selectively pass gas treatment particles from the treatment particle bed into the gas riser such that the gas treatment particles become entrained and mixed with the gas flow within the riser. A first and a spaced second baffle may be positioned in the gas chamber and used to direct the gas flow passed into the gas chamber. The gas treatment methods include selectively passing at least some of the treatment particles into the gas flow so that the treatment particles become entrained with the gas to effect either or both of the thermal regulation and decontamination of the gas. At least one aeration nozzle is placed in communication with the flow control device, and a supply of a pressurized fluid is selectively passed therethrough to fluidize the gas treatment particles within the flow control device.
