    摘要： A thermal mixer reduces the temperature of flue gas supplied to a fabric filter. Two spray dry absorbers are operable to cool flue gas. A housing of the mixer has first and second inlet passages for gas from the absorbers, an outlet passage for gas to the fabric filter, and a mixing passage. A set of damper vanes extends in the mixing passage and has a mixing position for mixing the flue gases from the inlet passages to supply mixed gas to the outlet passage at relatively high pressure drop but lower temperature if one of the absorbers in not operating. They have a non-mixing position for passage of gases without mixing and at low pressure drop when both absorbers are operating. The invention can also be used to improve mixing of combined gas streams initially having different chemical compositions or amounts of particle loading.

    摘要： A static fluid mixer includes a cylindrical flow conduit and at least two inclined, axially spaced, and circumferentially offset internal baffle members for creating counter-rotating vortices in fluids passing through the conduit. The baffle members each have upstream edges spaced from an inner surface of the conduit by a first distance less than a radius of the conduit and downstream edges that are spaced from the inner surface of conduit by a second distance that is greater than the first distance. The baffle members can each have a trapezoidal shape with the downstream edge being smaller in length than the upstream edge thereof.

    摘要： The present invention provides an apparatus and method for accomplishing fluid disinfection by passing fluid flow through a uniform array of ultraviolet lamps having cross sections perpendicular to the direction of fluid flow that define channels for the fluid flow. Positioned next to the end of each lamp at the entrance of the fluid flow are triangular shaped delta wings having surfaces inclined at an angle to the direction of fluid flow. The interaction of the fluid flow with each delta wing creates a pair of vortices that rotate in the same direction or in directions opposed to each other. The counter-rotating vortices reinforce each other to minimize dissipation of their mixing strength as they move down the channel. Due to these co-reinforcing properties these counter-rotating vortices more promote efficient mixing of the fluid which is required to achieve more efficient use of the light in the UV disinfection systems, along with heat and/or mass transfer in chemical reactions. Although the present invention is described in particularity as embodied in a UV reactor system, it will be understood by those skilled in the art that the present invention has equal applicability to other types of arrayed flow systems in which increased fluid mixing is desired.

    摘要： A method for mixing one or more fluid streams or for mixing solid particles with one or more fluid streams involves flowing the materials to be mixed through a static fluid mixer. The mixer includes an elongated fluid flow conduit having a centrally located longitudinally extending axis and an inner generally cylindrical wall extending around said axis and defining a fluid flow path within the conduit which extends along the central axis of the conduit. The mixer also includes at least two circumferentially offset internal baffle members designed to create countery-rotating vortices in fluids passing through the conduit. The first baffle is in the form of an elongated inclined plate positioned in said fluid flow path at a first location in said conduit. This baffle plate has an upstream end, a downstream end and a longitudinal axis. The first baffle plate is mounted on a mounting which extends between the wall and the downstream face of the baffle plate so that the upstream end of the first baffle plate is spaced radially from the wall a first distance which is less than a radius of the conduit. The downstream end of the first baffle plate is spaced radially from the wall a second distance which is greater than said first distance so that the baffle plate is disposed at an angle relative to the longitudinal axis of the conduit. The second baffle member has a configuration and arrangement which is essentially the same as the first baffle, except that the second baffle member is circumferentially offset approximately 90 degrees and spaced longitudinally of the conduit from the first baffle member. The upstream ends of the baffle members are spaced from the wall so as to permit fluid flow around the upstream ends to thereby minimize eddy currents and the like behind the baffle members. This arrangement facilitates complete mixing of fluids with other fluids and/or with solid particles flowing through the conduit.
