Title:
微細泡生成パーツおよび微細泡生成装置
Document Type and Number:
Japanese Patent JP7381180
Kind Code:
B2
Abstract:
To provide a technology for efficiently making air bubbles of a gas/liquid mixture fine and outputting the air bubbles.SOLUTION: One of representative fine bubble generation parts of the present invention includes a duct for making a gas/liquid mixture obtained by mixing liquid and gas flow and outputting the gas/liquid mixture from a lead-out port, a porous cylinder arranged coaxially to an inner peripheral wall of the duct to have a porous lateral surface, a spacer provided with a peripheral space between the inner peripheral wall of the duct and the lateral surface of the porous cylinder, a guiding cone for extruding the gas/liquid mixture flowing inside the porous cylinder from the lateral surface of the porous cylinder by a cone surface arranged on an inner side of the porous cylinder to spread in the direction of flowing of the gas/liquid mixture to guide the gas/liquid mixture to the peripheral space, and a convergence part for guiding the gas/liquid mixture of the peripheral space to the inner side of the porous cylinder through the lateral surface of the porous cylinder by expanding a passage diameter in a section from a core bottom part of the guiding cone to the lead-out port.SELECTED DRAWING: Figure 1
