SUPERFINE MICROBUBBLE GENERATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a superfine micro bubble generation device capable of: generating superfine micro bubbles by uniformly diminishing bubbles into to a nano-level with a simple structure at a reasonable cost; and achieving stable generation of the superfine micro bubbles with reduced vibration and noise through reduction (control) of gas pulsation.SOLUTION: In a cylindrical casing body 50 which has an introduction port 30 to introduce fluid at one end and a lead-out port 40 to lead out the fluid at the other end, a superfine micro bubble generation device has: a flow rate increase section 70 which increases a flow rate of the fluid in series as the same flows from the introduction port to the lead-out port; a gas suction section 80 which allows external gas to be sucked into the casing body 50 where pressure therein is reduced by a fluid flow with the flow rate thereof increased in the flow rate increase section 70; and a superfine micro bubble containing fluid generation section 90 which generates the fluid mixed with superfine micro bubbles in a manner that shears the gas sucked through the gas suction section 80 by the fluid flow with the flow rate thereof increased in the flow rate increase section 70. The gas suction section 80 is provided with a pulsation control body 85 to control pulsation of the sucked gas.
