Patent ID: 7309379

Claim:
A moving bed adsorber apparatus comprising: a housing having a fluid inlet, a fluid outlet, an adsorbent inlet and an adsorbent outlet; a plurality of spaced-apart, downwardly sloped vane members having edges, said vane members being positioned within the housing such that contaminated fluid that enters through the fluid inlet will subsequently flow through spaces between said vane members; and, an adsorbent depth regulator positioned a spaced distance from the edges of the vane members and defining an adsorbent flow channel there between, at least a portion of said adsorbent depth regulator being porous to fluid flow; such that, a flow of adsorbent may pass through the adsorbent inlet, through the adsorbent flow channel, then out of the adsorbent outlet and, concurrently, a flow of contaminated fluid may pass through the fluid inlet, through spaces between the vane members and through adsorbent moving through the adsorbent flow channel, thereby causing contaminant to be adsorbed on to the adsorbent, and a remaining fluid from which the contaminant has been removed then flowing through the adsorbent depth regulator and out of the fluid outlet; wherein the vane members are spaced approximately 5-25 mm apart.
