PROBLEM TO BE SOLVED: To provide a gas dissolving device capable of increasing dissolution efficiency of a gas to a liquid while suppressing a steep rise in cost and downsizing the device.SOLUTION: A gas dissolving device 1 includes a dissolving tank 2 with an inside divided into a gas liquid mixing tank 6, an intermediate tank 7, and a gas liquid separating tank 8 in order from the upstream side to downstream side concerning a flow of a liquid 5 by a first partition wall 3 and a second partition wall 4, wherein a fluid flowing in the dissolving tank is mixed with the gas in the gas liquid mixing tank, a liquid in which the gas is dissolved is produced, and the liquid sequentially flows through the intermediate tank and the gas liquid separating tank and flows to the outside of the dissolving tank from a lower part of the gas liquid separating tank. A projection 50 is disposed in a part with which the fluid supplied to the gas liquid mixing tank and jetted is collided, and this projection generates a swirl flow in the fluid after collision. |
