Abstract
Provided is a fine bubble supply device and a fine bubble analyzing system capable of more stably supplying fine bubbles unstable in a liquid. A fine bubble generating device generates fine bubbles. A retention vessel stores a liquid therein, and an inlet pipe and an outlet pipe of the fine bubbles are connected to the retention vessel. The fine bubbles generated from the fine bubble generating device are introduced into the liquid in the retention vessel through the inlet pipe to be retained in the liquid. The fine bubbles retained in the liquid are led out to a supply destination (fine bubble characteristic evaluation device) through the outlet pipe.
Claims11
A fine bubble analyzing method comprising:
- a step of generating fine bubbles using a fine bubble generating device;
- a step of introducing fine bubbles generated by the fine bubble generating device into a retention vessel in which a liquid including fine bubbles is stored and to which an inlet pipe and an outlet pipe of the fine bubbles are connected,
- a step of evaluating a characteristic of the fine bubbles supplied by the retention vessel to a supply destination;
- wherein the fine bubbles generated from the fine bubble generating device are introduced into the liquid including fine bubbles in the retention vessel through the inlet pipe and thus retained in the liquid, and the liquid retaining the fine bubbles is led out to the supply destination through the outlet pipe such that the liquid is in a state of laminar flow inside the outlet pipe,
- wherein the outlet pipe has an inner diameter and a liquid flow velocity inside the outlet pipe set such that a Reynolds number is 1,250 or less.
