<p>PURPOSE:To enhance the dissolving efficiency of oxygen, by providing a liquid inlet, a gas inlet, an outer nozzle and an inner nozzle to a jet fluid generator and forming a dispersing device into such a tubular shape that the inner diameter is reduced from the inlet thereof down to part of the way toward the discharge port. CONSTITUTION:A gas-liquid mixer is constituted of a jet fluid generator 1 and a dispersing device 2 and the jet fluid generator 1 has a liquid inlet 12, a gas inlet 13, an outer nozzle 11 and an inner nozzle 14. The liquid supplied to the jet fluid generator 1 is injected in the jet fluid generator 1 from the liquid inlet 12 through the inner nozzle 14. The dispersing device 2 consist of a pipe opened at both ends and the inner diameter is largest at the inlet 21 and is continuously reduced from the inlet 21 at least down to part of the way toward the discharge port 22. By this configuration, even if the mixing ratio of gas/liquid of an air bubble-containing stream is enhanced to 2/1-3/1, a fine pulverizing state of air bubbles can be held without generating the uniting of air bubbles.</p> |
