Document Type and Number:
Japanese Patent JP2018122294
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a small-sized bubble generation nozzle which can generate fine bubbles with good efficiency.SOLUTION: A bubble generation nozzle comprises: a gas-liquid mixing chamber 120m which has a space of a circular cross section and forms a loop flow; a liquid supply hole which is provided on one end side of the gas-liquid mixing chamber 120m and supplies a pressurized liquid to the gas-liquid mixing chamber 120m; a gas supply hole in which a gas is flown; a gas supply path 120t which is provided on the other end side of the gas-liquid mixing chamber 120m, and supplies the gas flown in from the gas supply hole to the gas-liquid mixing chamber 120m while spirally circulating the gas around a central axis of the liquid supply hole so that the gas is directed to one end side of the gas-liquid mixing chamber 120m along a circumference of the space of the gas-liquid mixing chamber 120m; and an exhaust nozzle 122g which has a hole diameter larger than a hole diameter of the liquid supply hole, and ejects a bubble-containing liquid in which the liquid and the gas are mixed in the gas-liquid mixing chamber 120m.SELECTED DRAWING: Figure 6
