Patent ID: 7897121

Claim:
A fluid reactor for facilitating mixing and/or chemical reaction comprising: an elongated cylindrical flow chamber having a first flow inlet at one end, and a flow outlet at another end, the first flow inlet being operable to admit a flow of a first fluid into the flow chamber, a second flow inlet through a wall of the flow chamber at a position downstream of the first flow inlet, the second flow inlet being operable to admit a relatively low mass flow of a second fluid into the flow chamber; and a cone-pi element disposed in a position, centered within the chamber, downstream of the second flow inlet and having an upstream conical portion with a leading apex generally facing the first flow inlet, an intervening cylindrical portion, having a uniform diameter and a downstream conical portion with a trailing apex generally facing the flow outlet, the cone-pi element being attached to a wall of the flow chamber by at least one strut, the cone-pi element being operable to cause the entire fluid flow to move over the upstream conical portion, none of said fluid flow entering the cone-pi element, to produce cavitation and/or vortical flow within the flow stream to effectuate mixing and/or chemical interaction of the first fluid and the second fluid, and to deliver a mixed and/or reacted fluid from the flow outlet.
