GENERATION METHOD, GENERATOR AND GENERATING NOZZLE OF MICROBUBBLE AND LINE WASHING DEVICE

摘要

PROBLEM TO BE SOLVED: To increase the generation rate of microbubbles by uniformly applying a collision opportunity to an entire liquid stream due to the collision of mutual bubble-containing high pressure sheet-like liquid streams in a linear state using a microbubble generating nozzle with a simple structure.SOLUTION: In a sheet-like sealed space Vformed in a nozzle N: bubble-containing high pressure sheet-like water streams Scollide mutually in a linear state at a collision angle of 180° and then a microbubble water stream Sis generated; and the microbubble water stream Sis discharged from a discharge port 15 being disposed in the vicinity of the collision part of the nozzle Nand having a rectangular shape with a high slenderness ratio.SELECTED DRAWING: Figure 3
