曝気および他の目的のための泡生成
Document Type and Number:
Japanese Patent JP4975108
Kind Code:
B2
Abstract:
A method of producing small bubbles (90) of gas in a liquid comprises a source (16) of the gas under pressure, a conduit (64a) opening into a liquid and oscillating the gas passing along the conduit at a frequency between 1 and 100 Hz. The oscillation is effected by fluidic oscillator (10) comprising a diverter that divides the supply into respect outputs (A, B), each output being controlled by a control port, wherein the control ports are interconnected by a closed loop (22). There may be at least two of said conduits (62a, 64a), each output port being connected to one or the other of said conduits, in which one phase of the oscillating gas is employed to drive liquid across the conduit (64a) after formation of a bubble in the other phase of oscillation, whereby the bubble is detached by the force of said driven liquid.
