NOZZLE FOR GENERATING MICRO AIR BUBBLES

摘要

PROBLEM TO BE SOLVED: To provide a nozzle for generating micro air bubbles of micro meter size using low pressure water flow with a simple constitution.

SOLUTION: The nozzle can generate micro air bubbles of micro meter size by a following structure. In a liquid flow path, a throttle part having a horizontal hole is provided. Venturi effect is used to suck air into the liquid flow and air bubbles are generated in the liquid flow. The liquid flow containing these bubbles is made to pass through a flow path where structures having tangled linear bodies and/or lengthy thin pieces are packed.
