Gassing device useful for introducing gas in liquid, preferably for ventilating wastewater, comprises support body with connection piece for gas-permeable membrane tube, inlet opening, inner element, and channel system

摘要

Gassing device (10) comprises a support body (16) with at least one connection piece for a gas-permeable membrane tube, an inlet opening (24) for the gas, an inner element (18), which is arranged at least partly in the connection piece, and at least one channel system, which is present between the inner element and the connection piece. The membrane tube is fixed fluid-tightly on the connection piece and the inner element, preferably by means of tube rings (38, 40), and an intermediate space of the membrane tube is connected with the inlet opening via the channel system.
