<p>PROBLEM TO BE SOLVED: To provide a gas-liquid mixer capable of preparing liquid containing air bubbles of nano-level which can enlarge an application range on industry and, at the same time, can prevent air entrainment.SOLUTION: Fine air bubble generation means which turns supplied gas into fine air bubbles to diffuse the air bubbles into liquid is arranged on the neighborhood of a suction port part of a submerged pump immersed under liquid and, on the other hand, gas-liquid mixing means which further makes the fine air bubbles finer and evenly mixes the fine air bubbles with the liquid is connected to an ejection port part of the submerged pump. Therein, the gas-liquid mixing means includes a gas-liquid supply path communicated with the ejection port part of the submerged pump and dispersion-mixing channels which are communicated with the gas-liquid supply path, cause the air bubbles and liquid to flow while meandering the air bubbles and liquid, and make the air bubbles fine to perform dispersion and mixing into liquid, and a number of dispersion-mixing channels are communicated while leaving intervals in the axial direction and in the circumferential direction of the gas-liquid supply path and cause liquid containing air bubbles to flow out from a terminal part of each dispersion-mixing channel.</p> |
