Title:
拡張リング
Document Type and Number:
Japanese Patent JP4542093
Kind Code:
B2
Abstract:
A mass transfer column ( 10 ) is provided with at least one vapor-liquid contact tray ( 12 ) that is disposed within the open internal region ( 14 ) defined by a shell ( 16 ) of the column ( 10 ). At least one expansion ring ( 26 ) underlies and supports the vapor-liquid contact tray ( 12 ). An expander ( 38 ) is associated with first and second end segments ( 32, 34 ) of the expansion ring ( 26 ) that define a cutout ( 36 ) in the expansion ring ( 26 ). The expander ( 38 ) includes brackets ( 48 ) welded to the end segments ( 32, 34 ) and a threaded member ( 50 ) that extends through the brackets ( 48 ) and carries nuts ( 54 ). Turning the nuts ( 54 ) against facing surfaces of the brackets ( 48 ) causes the first and second end segments ( 32, 34 ) of the expansion ring ( 26 ) to be forced apart to cause an increase in the circumference of the expansion ring ( 26 ), thereby sealing the expansion ring ( 26 ) against the inner surface of the column shell. At least one seal plate ( 58 ) is positioned on the threaded member ( 50 ) to block the cutout ( 36 ) in the expansion ring ( 26 ) Rods ( 27 ) extend between the expansion ring ( 26 ) and a support ring ( 24 ) that is welded to the column shell ( 16 ) to transfer a portion of the load carried by the expansion ring ( 26 ) to the support ring ( 24 ).
