A gas-liquid contact tower comprises a tower shell and a plurality of superimposed generally horizontal contact plates mounted in vertically spaced relation within the tower shell, with the plates being grouped into at least one subassembly thereof. A supporting and sealing arrangement is provided for removably supporting said plate subassembly within the tower shell and for preventing any of the contact liquid from bypassing the plate subassembly. The supporting and sealing arrangement includes a first annular component permanently secured and sealed to adjacent inner surfaces of the tower shell, and a second annular component joined circumferentially to the plate subassembly and sealed detachably and circumferentially to the first supporting and sealing component. An annular gasket arrangement is inserted generally between the first and second components of the supporting and sealing arrangement and is circumferentially loaded by a loading arrangement mounted on at least one of the components. A contact plate subassembly for use in a contact tower comprises a top contact plate and a bottom contact plate, together with a number of intermediate contact plates. A plurality of spacing and sealing rings alternate with the plates. The top or bottom contact plate of the subassembly has a peripheral extension or flange for mounting purposes, and a stabilizing ring is secured to the mounting extension.
A gas-liquid contact tower comprising a tower shell, a plurality of superimposed generally horizontal contact plates within said tower shell, said plates being grouped into at least one subassembly thereof, supporting and sealing means for removably supporting said subassembly within said tower shell and for preventing any of said contact liquid from by-passing said subassembly, said supporting and sealing means including a supporting ring sealed to adjacent inner surfaces of said tower shell, a suspending ring detachably secured to said supporting ring and having an inner periphery projecting inwardly of said supporting ring, said subassembly having a plate at one end thereof projecting radially outwardly of said subassembly, the radial projection thereof being detachably secured to the inward peripheral projection of said suspending ring, and annular gasket means inserted between said supporting ring and said suspending ring and between said suspending ring and said radial plate projection, said gasketing means being substantially uniformly loaded at detachable junctions between said supporting ring and said suspending ring and between said suspending ring and said radial subassembly projection.
In a gas-liquid contact tower the combination comprising a tower shell, a plurality of superimposed generally horizontal contact plates mounted in vertically spaced relation within said tower shell, said plates being grouped into at least one subassembly thereof, supporting and sealing means for removably supporting said plate subassembly within said tower shell and for preventing any of said contact liquid from bypassing said plate subassembly, said supporting and sealing means including a first annular component permanently secured and sealed to adjacent inner surfaces of said tower shell and a second annular component circumferentially joined to said plate subassembly and positioned in substantial alignment with said first component, gasketing means for preventing passage of fluid between said components, said gasketing means being inserted generally between said components and circumferentially loaded by loading means mounted on at least one of said components, and means on said first component for supporting said second component thereat, said second supporting and sealing component including a peripheral flange extending outwardly from said plate subassembly and a suspending ring detachably and circumferentially joined to said flange and to said first component, said gasket means being circumferentially inserted between said first component and said suspending ring and between said suspending ring and said flange, said gasketing means being loaded by the detachable joining of said suspending ring to said first component and to said plate subassembly flange.
