Abstract
A chemically reactive electro-fluidized bed gas purification arrangement and method for cleaning a dirty gas stream including chemically reactive materials and entrained particulate materials wherein means are provided to impose a selected electrical charge upon the entrained particulate materials, and wherein the dirty gas stream is contacted with at least one fluidized bed of particulate purification material including reagent material of selected chemical composition receptive to combination with the chemically reactive materials of the dirty gas stream where the reactive bed can be electro-fluidized and the dirty gas stream is passed through at least one electro-fluidized bed where the electrical charged particulate matter entrained in the dirty gas stream adhers to particles of the electro-fluidized bed which act as electro-static collection sites for the particulate material.
