Gas-liquid contacting apparatus
A ceramic nozzle support structure (13) comprises: (A) a ceramic nozzle (12) having a ridge portion (24) on the outer peripheral surface of a nozzle body (23); (B) a tightening flange (16) including a flange body (30) having an aperture larger than the outside shape of the nozzle body and a central cylindrical portion (28) extending substantially concentrically with the nozzle body from lower surface of said flange body, the tightening flange having through holes (26) in the wall of central cylindrical portion thereof; (C) a support nozzle (14) consisting of a cylindrical body having an inside diameter larger than the central cylindrical portion of tightening flange and connected to the tightening flange by bolting (32, 36, 38) via the flange body at the upper portion of the cylindrical body; and (D) an elastomeric resin filled in a space (18) between the nozzle (12) and the support nozzle (14) so that the outside and inside of the central cylindrical portion of tightening flange are integrated via the through holes. <IMAGE>
