PROBLEM TO BE SOLVED: To provide a circulation type gas/liquid mixer capable of sucking more gas at a fixed flow rate of a liquid and improving the gas/liquid mixing efficiency.SOLUTION: A gas/liquid mixer includes a large-tube-diameter portion forming a large-diameter passage, a first small-tube-diameter portion communicating with the large-tube-diameter portion and forming a first, relatively small cylindrical small-diameter passage, a second small-tube-diameter portion forming a second small-tube-diameter passage communicating with the first small-tube-diameter portion, a conical-tube-diameter portion communicating with the second small-tube-diameter portion and forming a first cylindrical passage increasing gradually in diameter from the second small-tube-diameter portion, and a gas introduction hole introducing a gas from the outside into the second small-tube-diameter portion, wherein the diameter of the first small-tube-diameter portion is smaller than that of the second small-tube-diameter portion. |
