Title:
MICRO-BUBBLE GENERATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/227411
Kind Code:
A1
Abstract:
A micro-bubble generating device, comprising a blower mechanism and a microporous aerator (1), and further comprising a stirring mechanism. The blower mechanism is composed of a fan (2) and an air pipe (3). The fan (2) communicates with the microporous aerator (1) by means of the air pipe (3). The stirring mechanism is composed of an agitator (4) and a driving unit (5) used for driving the agitator (4) to rotate. The agitator (4) is disposed above the microporous aerator (1), and there is a distance D between the lower surface of the agitator (4) and the upper surface of the microporous aerator (1). The distance between the upper surface of the microporous aerator (1) and the water surface is d, and D is less than 1/2d. The agitator (4) is a radial flow agitator or a mixed flow agitator. The micro-bubble generating device has the advantages of low energy consumption, a good effect and stable operation.
