<p>PURPOSE: To increase the discharge of a liq. contg. dissolved gas at the time of purifying the water in the closed waters, etc., to increase the content of fine bubbles in the discharge and to continuously discharge the fine bubbles. CONSTITUTION: A pressurized liq. contg. dissolved gas is supplied from one end of an inner cylinder 7, the other end is closed, and the cylinder is pierced with minute-inner-diameter injection holes 10. An outer cylinder 14 having a discharge port 16 and with which the liq. injected from the holes 10 is collided is provided outside the injection holes 10. The flow velocity of the liq. is suppressed by the injection from the holes 10 and the outer cylinder 14, the pressure is released at a breath, and many fine bubbles are discharged. When the original liq. is supplied to the device 1 through a pump, ejector and pressurized tank, the water is purified by the aeration, coagulated floc of fine bubbles and the adsorption and flotation of the suspended matter.</p> |
