Title: Degassing column with equally spaced perforated plates - supported by peripheral ring and lugs and crossed by downcomers with adjustable overflow height
Inventor: KUXDORF BERNHARD DIPL ING
IPC: B01D19/00
Filed: 1977-04-28
Abstract: A degassing column has a several equally spaced plates that have perforations with a dia. 5 mm. There is a small gap between the edge of the plate and the inside of the column casing. These plates are supported around their circumference by several lugs fixed to the inner surface of the column. In addition there is a rectangular section ring (5 to 20 mm wide) welded to the inside surface of the column, that spans between the lugs. The ring sections end just short of the lugs to leave a free space between the end of the ring sections and the lugs. Passing through each plate are eccentrically positioned downcomer pipes, which extend down almost to the plate below. A metal disc, at least the dia. of the downcomer pipe, with no perforations, is placed immediately below the downcomer on the plate below. The height of downcomer extending above each plate sets the liq. level. The tops of the downcomers may be fitted with a sleeve to enable adjustment of the height above the plate. Used in degasification columns, e.g. to eliminate monomers from polymers. Design avoids solid deposits on the plates and column walls. Because the ring is welded to the column it does not have to be supported.
