Title:
GAS DISSOLVING DEVICE
Document Type and Number:
Japanese Patent JP3609014
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a gas dissolving device which has a relatively simple structure, can work with low energy and dissolve a gas such as oxygen and air into a liquid such as water efficiently.
SOLUTION: This gas dissolving device is provided with a submersible pump 2 that is disposed at the starting end of an inner flow passage to suck a liquid such as water from the outside, an injection tube 3 that is formed in the inner flow passage on the downstream side of the submersible pump 2 and can suck a gas from the outside by internal negative pressure, a dissolution tube 4 that is connected to the downstream side of the injection tube 3, and a discharge head 5 that is disposed on the downstream side of the dissolution tube 4, at the trailing end of the inner flow passage. A spiral strip 4a is formed along the inner periphery of the dissolution tube 4 for generating a forced spiral flow.
