<p>PCT No. PCT/DE94/01466 Sec. 371 Date Jun. 11, 1996 Sec. 102(e) Date Jun. 11, 1996 PCT Filed Dec. 10, 1994 PCT Pub. No. WO95/16514 PCT Pub. Date Jun. 22, 1995Described is a gas-introduction device designed to introduce a gas into a liquid. The device comprises at least one gas-feed manifold (10) and a multiplicity of tubular feed-in elements (12) which are open at the free end. Each feed-in element is surrounded by a perforated tubular membrane (14). A gas-supply line in each feed-in element terminates in the vicinity of the membrane. Each feed-in element comprises two support elements (46, 48) extending out from a central element. The central element has a flange which is designed to be fastened to the outside of the gas-feed manifold. A gas-supply line leads from a bore in the gas-feed manifold, via a central line (26) and two branch lines (28) leading off the central line (26), into longitudinal grooves behind the membrane. The central line and the branch lines are located in the central element. The feed-in element is a monobloc construction including the central element and the membrane-support elements.</p> |
