Embodiment Construction

[0045] figure 1 The reversing elbow 1 of the downcomer 2 for discharging the multiphase flow medium S is shown in . For the downcomer 2 , a small section is shown in the upper region of the reversing elbow 1 . Downpipe 2 is connected to reversing elbow 1 . A multiphase flow medium S is understood to mean a flow medium which contains, inter alia, water, solids and air. like figure 2 As shown, the flow medium S flows down into the region of the downcomer 2 and enters the reversing elbow 1 at the inlet as a wall flow. Water and solids flow substantially along the inner wall 17 of the downcomer 2 and form an air core in between. flow direction in figure 2 Marked by F.

[0046]The reversing elbow 1 includes a first pipe section 3 extending along a first central axis M1, a curved section 4 adjacent to the first pipe section 3 and having a curved outer side 5 and a curved inner side 6, and a curved section 4 adjacent to the second central axis M2 Extended second pipe section...

Abstract

A reversing elbow (1) of a downcomer (2) for discharging a multiphase flow medium (S), in particular a multiphase flow medium (S) comprising water, solids and air, comprising: along a first central axis (M1) a first pipe section (3) extending, adjoining the first pipe section (3), a curved section (4) extending along the curved midline (M) and having a curved outer side (5) and a curved inner side (6), and adjoining A second pipe segment (7) that bends the segment (4) and extends along the second central axis (M2). With the guide element (8) arranged inside on the curved outer side (5), the cross-sectional shape of the curved section (4) is changed in such a way that the flowing medium (S), in particular water and solids, can be restrained, especially prevented, from transversely Movement in the direction of flow.

Description

technical field [0001] This invention relates to reversing elbows for downcomers. Background technique [0002] The downpipe serves for the discharge of waste water and is arranged in a building extending substantially vertically. However, in many downcomers there are also sections that run horizontally or slightly obliquely (eg at an angle of a few degrees) to the horizontal. For reversing from vertical to horizontal, the vertically extending segment is connected to the horizontally extending segment by a reversing elbow. [0003] Such a reversing elbow is known, for example, from EP 1 882 786 . [0004] In this case, the transition between the vertically extending section and the horizontally extending section is preferably configured such that the waste water is diverted with as little loss as possible. The waste water therefore still enters the horizontally extending section with great energy, so that the waste water can flow as far as possible through the horizontall...
