<p>A two-fluid mixing device capable of suspending air bubbles in liquid by breaking a surface tension by the force of vortexes on a liquid side, not by a gas pressure, wherein, when a gas (9) side pressure is set higher than a static pressure on a liquid (10) side (= total pressure - dynamic pressure), the air bubbles are formed convex on the liquid (10) side but, when a hole (1) diameter is small, the air bubbles cannot be grown beyond the balanced state of the surface tension of the liquid (10) with the pressure of the gas (9), the liquid (10) flows through a narrow flow passage on the outside of a ceramic cylinder (3) at a high velocity so as to exceed a critical Reynolds number, and thus the flow of the liquid (10) becomes a turbulent flow and fine vortexes break the surface tension of the air bubbles, and the gas (9) becomes fine bubbles, entrapped into the liquid (10), and discharged continuously, whereby the device capable of dissolving the remarkably large amount of gas (9) into the liquid (10) can be provided easily at a low cost.</p> |
