초록 ▼

A vessel is adapted to contain a liquid phase and a tubular guide baffle in the vessel has spaced open ends one of which at least in part bounds a venturi-shaped passage. A rotary impeller in the vessel has an axial inlet communicating with the one open end and a plurality of peripheral outlets which communicate with the axial inlet. A drive is provided for rotating the impeller so that centrifugal action causes expulsion of liquid phase from the outlets and thereby creates suction in the venturi-shaped passage to draw additional liquid phase from the guide baffle into the inlet. Gas admitting arrangements are provided, including a plurality of nipples communicating with the passage and with a conduit through which gas is supplied, so that the suction in the venturi-shaped passage draws gas from the source via the conduit and the nipples and the gas becomes admixed with the liquid phase.

대표청구항 ▼

In an apparatus for mixing a liquid phase and a gaseous phase, particularly a fermentor for biologically growing microorganisms, a combination comprising a vessel adapted to contain a liquid phase; a tubular guide baffle in said vessel and having spaced open ends one of which at least in part bounds a venturi-shaped passage having a throat portion; a rotary impeller mounted in said vessel for rotation about an axis and having an axial inlet communicating with said open end, and a plurality of peripheral outlets which communicate with said axial inlet; drive means for rotating said impeller about said axis so that centrifugal action causes expulsion of liquid phase from said outlets and creates suction in said venturi-shaped passage to thereby draw additional liquid phase from said guide baffle into said inlet; and gas admitting means including a conduit which communicates with a source of gaseous phase, and a plurality of tubular nipples each having an elongated tubular end portion which extends into said throat portion in direction generally transverse to the axial flow of liquid phase, each tubular end portion terminating in a bevelled discharge port which is inclined at a substantially constant angle of inclination relative to the elongation of the respective tubular end portion and which faceS generally downstream of the axial flow of liquid phase, said discharge ports communicating with different locations of said passage so that the suction in said throat portion of said passage draws said gaseous phase from said source via said conduit and ejects said gaseous phase out of said discharge ports of said nipples across different transverse sections of said throat portion without requiring said gaseous phase to be in pressurized condition.
