ABSTRACT:
A degassing column comprising a tubular shell provided with a plurality of apertured plates; the plates are vertically spaced within said shell; a gap uniform in width over the periphery is left between each plate and said shell; each of said plates is penetrated by at least one eccentrically arranged conduit comprising a draining shaft in the upper portion thereof and a feed shaft in the lower portion below the penetrated plate; the apertures in said plates have a diameter of less than 5 mm; and a surface portion of each plate underneath each conduit is impermeable, said impermeable surface portion being one to two times the cross-section of said conduit. More specifically, each plate is supported by a plurality of generally wedge-shaped mountings fastened to the inside of the shell, and by a ring which is level with the said mountings and is fastened to the inside of the shell, the ring being interrupted at least in the regions of the said mountings. A capping sleeve is slipped over each draining shaft. The capping sleeve comprises an upper portion whose cross-section is similar to that of the draining shaft, and a lower portion of larger cross-section, which lower portion overlaps and is securely connected to the upper portion.
