MICROBUBBLE-GENERATING DEVICE

摘要

The disclosed device has a simple configuration, is portable and, for the size of the device, allows efficient microbubble generation in liquids. The microbubble-generating device (1) is provided with a microbubble generator (10) that introduces a liquid and a gas, forms the gas into microbubbles in the liquid and discharges same. The microbubble generator (10) comprises a vapor-liquid-generating tank (11) and an outer shell tank (12) and the space therebetween is configured as a channel for the liquid. A plurality of liquid supply ports (17) are provided in the upper part of said channel and supply liquid through the channel into the vapor-liquid-generating tank (11) from the liquid supply ports (17). Inside the vapor-liquid-generating tank (11), a circling flow (C) is generated by the supplied liquid and a negative pressure cavity (V) is thereby generated near the axis of the cylinder (S). From the gas supply (13), gas is supplied from the outside by the action of the negative pressure cavity (V) or by additionally forcing the gas supply. The supplied gas is formed into microbubbles by the circling liquid flow and is discharged from the vapor-liquid outlet (16) as a vapor-liquid.
