微細気泡発生ノズル

Japanese Patent JP7232713

B2

To provide a technique capable of including a large amount of fine bubbles in gas-dissolved pressurized water outflowing to an outflow position.SOLUTION: A fine bubble generation nozzle includes: a pressure-reduced circulation part reducing the pressure of gas-dissolved pressurized water dissolving a gas in water and having a pressure reducing pipe, an inlet side opening part and an outlet side opening part; a first collision chamber being disposed at the downstream side of the pressure-reduced circulation part and having a flow passage area larger than the opening area of the outlet side opening part, a first flow passage space passing the gas-dissolved pressurized water discharged from the outlet side opening part, a first collision wall being disposed in a range opposing the outlet side opening part and changing the flow direction of the gas-dissolved pressurized water by that the gas-dissolved pressurized water discharged from the outlet side opening part collides, a projection disposed on the collision wall and projected toward the outlet side opening part from the first collision wall; and an outflow part where the gas-dissolved pressurized water after passing the first collision chamber outflows to an outflow position.SELECTED DRAWING: Figure 1
