APPARATUS FOR GENERATING MICRO BUBBLE AND MICRO BUBBLE DEVELOPMENT SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for generating micro bubbles which generates micro bubbles efficiently in energy and more finely. SOLUTION: The apparatus 1 for generating micro bubbles is provided with a circulation channel 101 from which the gas-liquid mixed phase flow is supplied, a pressure receiving part 12 to receive the gas-liquid mixed phase flow at one end side of the circulation channel 101 and a discharge channel 13 to generate micro bubbles by introducing the gas-liquid mixed phase flow from the side face of the circulation channel 101 at the proximity of the pressure receiving part 12. The discharge channels 13 are plurally connected with the side face of the circulation channel 101. The inner surface of the discharge channel 13 is formed to a taper shape so that the exit diameter of the discharge channel 13 becomes a large diameter. Individual discharge channel 13 is radially connected around the axis of the circulation channel 101 as a center. Individual discharge channel 13 is arranged so that micro bubbles are discharged to the axis direction of the circulation channel 101. The surface of the pressure receiving part 12 to receive the gas-liquid mixed phase flow is subjected to bending processing. The aperture angle of the discharge channel 13 may be set so that the differential pressure of the entrance and exit of the discharge channel 13 become maximum. COPYRIGHT: (C)2008,JPO&INPIT
