Abstract
The device is a gas-liquid mixing device having a venturi structure in which a throat portion and an enlarged diameter portion are provided in a main passage through which a liquid passes, the gas-liquid mixing device including a collision chamber provided on an outer periphery of the enlarged diameter portion, and a stirring chamber provided downstream of the enlarged diameter portion. A collision flow path communicating with the collision chamber and causing a gas-liquid to collide with an outer peripheral wall, a straight flow path through which the gas-liquid passing through a central portion of the enlarged diameter portion travels straight, and an outer ring flow path through which the gas-liquid flows from the collision chamber to the stirring chamber are formed downstream of the enlarged diameter portion. The gas-liquids from the outer ring flow path and the straight flow path are stirred in the stirring chamber.
