Patent ID: 8905080

Claim:
A mixer or heat exchanger device for processing and conditioning of fluid or fluidized material transported through the device, wherein the device comprises: a central inner tube defining a central cylindrical passageway for transport of at least one compound therethrough, a double-walled cylindrical housing comprising an inner cylindrical tubular wall surrounding the central inner tube and defining a central tubular space for transport of a fluid or fluidized material therethrough, and an outer cylindrical tubular wall surrounding the inner cylindrical tubular wall, wherein the inner and outer cylindrical tubular walls define an annular chamber therebetween having a fluid inlet and a fluid outlet, and wherein the fluid inlet and fluid outlet of the annular chamber are connected to a heat exchange unit for continuously transporting a heat exchange fluid through the annular chamber, and upstream and downstream porous elements positioned within the central tubular space of the inner cylindrical tubular wall consisting of a solid foamy structures; wherein the central inner tube includes an outlet positioned between the upstream and downstream porous elements for introducing the at least one compound flowing through the central inner tube to the fluid or fluidized material being transported through the central tubular space, wherein each of the upstream and downstream porous elements comprise a plurality of hollow spaces that are connected to each other and form an interconnected network, that allows cross-flow of the reaction medium through the hollow spaces thereof, and wherein each of the upstream and downstream porous elements and the inner cylindrical tubular wall of the double-walled cylindrical housing are made in the form of a one piece structure.
