JET INJECTION DEVICE

WIPO Patent Application WO/2018/198994

A1

[Problem] To provide a jet injection device that incorporates nanobubbles (ultrafine bubbles) in a mist and injects the mist at a high speed. [Solution] This jet injection device comprises: a two-fluid nozzle (3) configured from a circular nozzle outer cylinder (1) and an air connection tube (2) integrally and perpendicularly connected to the nozzle outer cylinder (1); a nanobubble generation device (4) that supplies the nozzle outer cylinder (1) of the two-fluid nozzle (3) with high-pressure nanobubble water; and a compressor (5) that supplies the air connection tube (2) of the two-fluid nozzle (3) with high-pressure air. The gas-injected bubble water generated from the nanobubble generation device (4) is pressure-fed to the nozzle outer cylinder (1) of the two-fluid nozzle (3), and compressed air from the compressor (5) is pressure-fed to the air connection tube (2) of the two-fluid nozzle (3). In the two-fluid nozzle (3), the high-pressure gas-injected bubble water and the compressed air serve as a gas-liquid fluid mixture, and is injected at a high speed in mist form from a nozzle cylinder (8) of the two-fluid nozzle (3).
