Device for feeding gas into a liquid |
摘要 |
The device for feeding a gas, particularly air into a liquid body present in an open container, includes a housing whose lower part is provided with a gas inlet opening and whose top wall is formed with a plurality of perforations. An inner perforated partition divides the housing into an upper chamber and a lower chamber communicating with the inlet opening. To create a dynamic pressure gradient between the two chambers, the perforations in the inner partition have substantially smaller diameter than the perforations or gas outlet openings in the top wall of the housing and the combined area of the perforations in the inner partition is substantially less than the cross sectional area of the gas inlet opening.
