Abstract:
1. An improvement in a media containment system for a containment of a media used in a purification of a contaminated air stream within a vertically standing air stream remediation plenum; said improvement allowing of a creation of a variety of sizes of media containment systems ranging from a small to a very large commercial size unit, and, allowing of a greater flow of said air stream through said plenum per unit of time, and, doing so with a less pressure drop from an inlet side to an outlet sided of said plenum, and using a less amount of energy than was possible in the prior art; said media containment system improvement comprising in part, a pair of media support frameworks, each of said frameworks comprising a sandwich of a set of three layers of material that are fused together into a singular element; a. an external layer comprised of a corrosion resistant Fiberglass Reinforced Plastic which said external layer is created in a form of a basket weave diamond shaped lattice pattern having an approximately 68 percent of a through space area between bands of Fiberglass Reinforced Plastic material, b. a central layer comprising a corrosion resistant plastic screen material having a pore size comprising a pore space to solid ratio of approximately 50 percent of a total surface area of said screen with said pores being of a slightly smaller size than a granule size of a media it is to be used to contain, and, c. an internal layer comprised of a corrosion resistant Fiberglass Reinforced Plastic; which said internal layer is created in a form of an open-weave diamond shaped lattice pattern having an approximately 68 percent through space area between said bands of Fiberglass Reinforced Plastic material; said basket weave diamond shaped pattern of said internal layer being of a creation in same design and in an alignment with said basket weave diamond shaped pattern of said outer Fiberglass Reinforced Plastic layer throughout a full vertical length of said framework wall, said framework being formed in a variety of sizes for a use in a containment of said media being used in said purification of said contaminated air stream; said contaminated air stream comprising an air stream containing corrosive vapors.
