LIQUID JETTING APPARATUS AND LIQUID JETTING METHOD

摘要

Technical Problem generate extremely small particles of uniform diameter and reduce abrasive wear of the nozzle region Solution to the Problem The liquid ejecting device uses pressurized gas to eject liquid as a spray of fine particles and is provided with internal gas-flow passageway 3 to supply pressurized gas, and a nozzle section 10 with a slit-shaped liquid ejecting opening 12 to discharge liquid. The nozzle section 10 is near the end of an elongated main unit 1 of the liquid ejecting device, and gas jet openings 13 to discharge pressurized gas are established between inclined nozzle surfaces and sidewalls of the main unit 1. The liquid ejecting opening 12 is connected with liquid-flow passageway 2 and the gas jet openings 13 are connected with the gas-flow passageway 3. Viewed in cross-section, the inclined nozzle surfaces are formed such that their extensions intersect above the liquid ejecting opening 12 on a line extending from the liquid ejecting opening 12, and pressurized gas is discharged as jets along the inclined nozzle surfaces to intersect in a manner that sandwiches the liquid in between and breaks-up the liquid-flow to produce a spray of fine particles.
