| 摘要 |
The invention relates to a column (1) for thermally treating fluid mixtures, comprising a cylindrical, vertically-aligned column body (2) that forms a column cavity (3) and a vertical inner surface (16), a plurality of trays (8) which are mounted in said column cavity (3) and vertically spaced apart from one another, at least one neck (11) arranged in the column body (2) and extending away from said column body (2), and a closeable inspection opening (9) formed at the neck (11). The claimed column is characterised in that, in a vertical cross-section of the column (1), the surface (15) of the lower intersection line of the neck (11), directed into the column cavity (3), or a tangent to the surface (15) of said lower intersection line of the neck (11), forms, together with the vertical inner surface (16) of the column body (2) which extends downwards from said neck (11), an angle in the range of 210° to 267°, at least in some sections. |
