"Column for mass transfer or heat exchange method of installation of a plurality of trays of contact within a column for mass transfer or heat exchange, and.The tray to contact ". A plurality of trays of contact fluid - fluid (16) of the type cross flow is provided inside a shell of a column for mass transfer or heat exchange (10).The trays (16) include platform tray (20) which are supported on the rings (18) fixed to an inner surface of the shell and tubes descendants (24) that are supported.Not by mounting bars typical shell (12), but the platform (20) of the underlying tray.The mechanisms for supporting the tubes descendants (24) in this way are support bracket (54) that are not trapped in the shell of the column, but, instead,Extends downwards from the tubes descending and rely on the platform of the tray (20) of the underlying tray.Alternate trays have side tubes (26) positioned downward in the openings at one or both ends of the platform of the tray (20).The support rings (18) in the trays have side tubes descendants may be truncated.In such a way that the rings do not extend into that part of the circumference of the shell where the openings of the tube downward side are located.In the other trays, rings complete 360 degrees can be used.Some or all of the tubes descendants have a segment of cam that extends into one or both of the side walls that support parts of the platform of the tray and which contains passages ofThe fluid.
