MANUFACTURING METHOD AND APPARATUS FOR HIGH-CONCENTRATION GAS DISSOLVED WATER, AND USING METHOD FOR MANUFACTURED HIGH-CONCENTRATION GAS DISSOLVED WATER
PROBLEM TO BE SOLVED: To provide a method and apparatus for manufacturing high-concentration gas dissolved water easily and at a low cost because various methods are conventionally used for manufacturing high-concentration oxygen dissolved water； however, all of such methods manufacture insufficient concentration and are infeasible in cost.SOLUTION: Two or more water streams 34 with oxygen-containing bubbles are made collide with each other to miniaturize the bubbles more finely and to dissolve, in large quantity, oxygen contained in the bubbles, in the water streams. Both the water streams collide with each other at an equal velocity to a sum of flow rates thereof. The impact reaches a magnitude of several times to a dozen or so times as many as that when a single water stream collides with a stationary surface and a maximum impact is applied to each of the water streams, so that the bubbles in the water streams are destroyed into miniaturized ones to accelerate dissolution into the oxygen water streams in the bubbles.【課題】従来から高濃度酸素溶解水の製造は種々の方法で行われてきたが、いずれも得られる濃度が不十分であったり、コスト的に実現が難しかったりした。本発明は、高濃度酸素溶解水を簡単かつ安価で製造できる方法や装置を提供する。【解決手段】酸素含有気泡を有する２以上の水流３４を衝突させることにより前記気泡をより微細化するとともに、気泡中の酸素を前記水流中に大量に溶解させる。両水流は両水流の流速の和に等しい速度で衝突するが、その衝撃は単独の水流が静止面に衝突する際の数倍から十数倍に達し、各水流に最大限の衝撃が与えられ、水流中の気泡が破壊されて微細化し、気泡中の酸素の水流中への溶解が促進される。【選択図】図１
