Document Type and Number:
Japanese Patent JP3697009
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To efficiently generate a stream of water and diffuse fine bubbles of air in the horizontal direction in a water area where such treatment is required to purity the water area.
SOLUTION: The device includes air passage members 13 which project radially from a propeller boss 2 of a screw propeller 1 so as to face a propeller vanes, and compressed air is supplied from an air compressor 10 to air blowoff parts 14 each provided with a porous plate at the rear edge of the member 13.
