COLUMN WITH BUBBLE CAP PLATES Russian patent published in 2012 - IPC B01D3/18 B01D3/32 B01D53/18 

FIELD: machine building.

SUBSTANCE: housing of vertical column with bubble cap plates consists of an end, rings and a cover plate. Flanges are fixed on end faces of rings. Bubble cap plates consist of bases in the form of a disc, bubbling caps, overflow pipes and a hydraulic seal. Vertical supports with an expansion gap are installed on the end and on each base. On external cylindrical surface of each base there is a circular slot into which a split ring made of two symmetrical semi-rings connected to each other is tightly installed. Bases are clamped between flanges of rings. Circular grooves are coaxially made on lower and upper surfaces of each base. Parts of bubbling caps, overflow pipes and hydraulic seal, which are embedded into the base, are located inside the circle of the smallest inner diameter of groove. Depth of groove is equal to 2/3 of the base thickness, and sum of widths of grooves is equal at least to the half thermal expansion of the base in radial direction. Housing and split rings are made from steel; internal surfaces of housing are protected with plastic fluor; parts located inside the housing are made from plastic fluor-4.

EFFECT: high reliability of flanged connections; high efficiency.
