摘要:
The invention relates to a liquid distributor for packed and/or filled columns, comprising individual, in particular horizontal layers involved in heat and/or material exchange. At least one layer of the column has a flooding, in particular for obtaining an increased density and for creating an accumulation of liquid and a specific surface for distributing the liquid. Said surface is greater than the surface of the overlying and underlying layers by a factor of 1.5 to 10, preferably by a factor of 2 to 3.

The invention relates to a column for carrying out reactive distillations in the presence of a heterogeneous particulate catalyst, with a packing or filling bodies, which form cavities in the column interior. The quotient for the hydraulic diameter for the gas stream through the packing or filling bodies and the equivalent diameter of the catalyst particles lies in the range of 2 to 20, preferably in the range of 5 to 10, whereby the catalyst particles are introduced loose into the cavities, distributed and removed under the influence of gravity.

A heat exchange apparatus for a cooling tower having first (34) and second (34) corrugated film, fill sheets. Each film fill sheet includes a plurality of arch shaped dimple features 46) oriented to forms various rows (44a, 44b) of the arch shaped dimple features. The first (34) and second sheet (34) are connected wherein the spacing between the sheets is equal to approximately 1.0 inches.

A distillation installation comprises a cross-corrugated packing module formed from strips of sheet material, comprising corrugations (8) that form alternately first and second main peaks (10; 12) , the corrugations (8) defining channels (14) having a general orientation (Dc) that is inclined to a general flow direction (Df) of a liquid. The strip 2 comprises adjacent rows (R) of inverted portions (22) that lie in the cross section of a channel (14) The strip defines a peak length (LC) between the said rows (R) and an inverted portion length (LPI). The inverted portion length (LPI) 10 different from the peak length (LC). Application to air distillation installations.
摘要:
The invention concerns a corrugated packing module for treating a fluid delimited by two channels (18). It comprises a running zone (4) whereof the channels define ridge lines (26) having a global sloping direction (Di) relative to a general direction of circulation (Df) of the fluid. The strip comprises a transition zone (6, 8) adjacent to the running zone (4). Each ridge line (26) of the transition zone (6, 8) extends inside a specific zone centered on a curve (A) which extends tangentially the ridge line (26) of the running zone (4). The radial width (Lr) is 10 % of the corresponding radius of curvature of the curve (A). The radius of curvature (Rc) of the curve (A) is at all points 1.5 times greater than the hydraulic diameter (Dh) of a channel (18). The invention is applicable to air distillation columns.

The invention relates to a packing for heat- and material-exchange columns, with a number of approximately perpendicularly arranged corrugated plates (or strips), with the side surfaces thereof lying adjacent to each other. The ribs of the above lie very close to each other and run from top to bottom, in the approximate form of an arc, whereby the ribs of two adjacent plates cross each other and the ribs in the upper region of a plate are straight and inclined to the upper, in particular, horizontal plate edge and, in the lower region of the plate, run bent in the form of an arc.
摘要:
Die geordnete Kolonnenpackung umfasst - in Gestalt von Strömungskanäle (2) enthaltenden Packungslagen - folienartiges Material (1) mit einer Feinstrukturierung (10). Das folienartige Material ist mit konkaven Strukturelementen (3b; Minuszeichen -) und konvexen Strukturelementen (3a; Pluszeichen +) in einer alternierenden Anordnung profiliert. Ein mittlerer Abstand a besteht zwischen Zentren benachbarter konkaver bzw. konvexer Strukturelemente. Dieser mittlere Abstand a ist wesentlich kleiner als ein Abstand zwischen Mittellinien (20) benachbarter Strömungskanäle. Das folienartige Material weist eine zweite Feinstrukturierung auf, die aus regelmässig angeordneten Durchbrüchen (5) besteht. Ein mittlerer Abstand b zwischen Zentren benachbarter Durchbrüche ist kleiner als der mittlere Abstand a, vorzugsweise um mindestens 50 % kleiner, und Ränder (51, 52) der Durchbrüche weisen jeweils eine konvexe und konkave Stellen (6a, 6b) umfassende Formgebung auf.
