Abstract: The invention relates to a mixing element (1) which is used to invert and mix flowing materials in a flow channel. Said mixing element comprises an axially-symmetrical base body (1a) which has a longitudinal axis (A). The base body (1a) comprises an outward-facing surface (1k) in relation to the longitudinal axis (A) and a front surface (Im) on each end of the longitudinal axis (A), in addition to a plurality of guiding elements (1b), which are rigidly connected to the base body (1a) on the surface (1k) via a base surface (1l). The guiding elements (1b) extend in a transversal manner in relation to the longitudinal axis (A), such that each guiding element (1b) comprises an inward-facing guiding surface (1d) in relation to the longitudinal axis (A) and an outward-facing guiding surface (1c) in relation to the longitudinal axis (A). A plurality of guiding elements (1b) are arranged in a successive manner in the direction of the periphery (A1) of the longitudinal axis (A).

Abstract: 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.

Abstract: 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.

Abstract: The mixer tube for low viscosity fluids contains plate-shaped elements which at one or at several points of the tube partially cover or block off its cross-section. The constrictions left free through the elements each comprise at least one gap-shaped region, with a longitudinal extent of this gap extending from tube wall to tube wall through the tube axis or from the tube wall through the tube axis to a second partial region. The gap subtends an angle with the tube axis in the range between about 20.degree. and 60.degree., preferably between 35.degree. and 45.degree.. A mixing path is provided after the constriction in the direction of flow. The fluid to be mixed can contain solid substances in suspension.

Abstract: The apparatus for treating fluids with ultraviolet radiation comprises at least one elongate cylindrical excimer radiator and at least one chamber (2) provided as a through-flow and treatment section for the fluid. The or each radiator has a discharge volume (10) and two electrodes (19, 20) with one of the electrodes (20) being arranged in the chamber (2) provided for the fluid. According to the invention, the electrode (20) in the fluid chamber (2) is formed as a static mixer for the fluid (21) as a so-called static mixer electrode.

Abstract: The static mixing device includes a tubular casing and at least one mixing element composed of individual webs which are secured in the wall of the casing. The webs are disposed in crossing relation to each other with a transverse spacing therebetween. The terminal ends of each web are secured within the wall of the casing by being shrink-fitted, soldered, welded or threaded.
