摘要： The inlet device has a horn-shaped passage piece at a peripheral wall of a column that feeds a fluid tangentially into the column so that the fluid enters into a vortex flow that rotates around an axis adjacent to a central axis of the column. A middle zone and discharge zone of the passage piece are made in the manner of a diffuser and abut the peripheral wall to extends over less than one half of the wall. A discharge zone of the passage piece through which flow takes place presets a middle flow direction of the fluid which extends along the peripheral wall and is inclined against the main direction.

摘要： The static mixer is used for a curing mixed product of flowable components that react to form a solidifying mass on mixing. The mixer has mixing chambers that are arranged behind one another and next to one another along a tube axis. Each mixing chamber is delineated by longitudinal walls oriented in the direction of the tube axis and by transverse walls standing transversely to the tube axis. Openings in the longitudinal walls and in the floor of each mixing chamber establish inlets and outlets for the mixed product. The corner of at least some of the mixing chambers upstream of an outlet in the longitudinal walls is filled in to form a concave surface for directing the flowable components towards the outlet. The transverse wall at an inlet to at least some of the mixing chambers is also formed with a concave surface for directing the flowable components through the inlet into the mixing chamber.

摘要： A mixing element is constructed for installation in a fluid-conducting conduit having an inlet opening of a first cross-section and an outlet opening of a larger second cross-section which is arranged in a plane disposed substantially normal to the main direction of flow. The mixing element has a cross-sectional design which increases substantially continuously from the first cross-section to the second cross-section. Flow-dividing layers are arranged in the mixing element such that a precise fitting of the mixing element into the substantially continuously expanding fluid-conducting means is made possible.

摘要： The tray column (1) has downcomers (3) for a transport of the liquid between adjacent trays (2). The liquid transport takes place in each downcomer through a plurality of discharge apertures (32) onto a loaded tray. Liquid flowing out of the discharge apertures in the form of jets (60) blending into a regionally divergent flow field (6) on striking the loaded tray, said flow field having transverse components of the flow speed with respect to a longitudinal main flow direction (61). Guide elements (4) are arranged beneath the discharge apertures and at a spacing from the loaded tray which each guide the impulse of liquid corresponding to the divergent flow field. The guide elements contribute to forming the transverse speed components such that the longitudinal component of the flow speed has a largely constant profile in each plane perpendicular to the main flow direction. The discharge apertures are preferably made in different sizes in a graduated fashion to be smaller in a central region than in adjacent flank regions.
