Title:
FINE BUBBLE GENERATION NOZZLE
Document Type and Number:
Japanese Patent JP2023178013
Kind Code:
A
Abstract:
To provide a technology to reduce cavitation sound.SOLUTION: A fine bubble generation nozzle includes a nozzle unit and an insulation body. The nozzle unit includes an inflow port into which gas-dissolved pressurized water in which a gas is dissolved in water flows, a decompression part for decompressing a pressure of the gas-dissolved pressurized water flowing from the inflow port, a first collision chamber provided on a downstream side of the decompression part having a first collision wall for changing a direction of a flow channel of the gas-dissolved pressurized water when the gas-dissolved pressurized water flowing from the decompression part collides with the first collision wall, a second collision chamber provided on a downstream side of the first collision chamber having a second collision wall for changing the direction of the flow channel of the gas-dissolved pressurized water when the gas-dissolved pressurized water passing through the first collision chamber collides with the second collision wall, and an outflow port from which the gas-dissolved pressurized water passing through the second collision chamber flows out. The insulation body is disposed at a position facing the outflow port at an outside the nozzle unit.SELECTED DRAWING: Figure 6
