In the gas-liquid pressurizing and mixing method and the gas-liquid pressurizing and mixing apparatus of the present invention, a flow path from top to bottom is formed step by step while repeating rapidity, and a gas-liquid mixed flow is caused to flow in this flow path. As a result, in the flow path, a gas flows in the upper part of the flow path and a liquid flows in the lower part of the flow path, and a flow having a wide contact area of gas and liquid is obtained. The static pressure inside the flow path is increased and the gas-liquid reaction and dissolution efficiency are increased by providing an outlet or a throttle downstream of the flow path that gradually flows from top to bottom while repeating the gradual repetition. Further, since the outlet is lower than the inlet of the gas-liquid mixed flow, the gas-liquid mixed flow becomes stagnant in the flow channel, and further, in the flow channel, the liquid having a higher density is easier to flow out than the gas. Therefore, the amount of gas stays in the flow channel more than that of the liquid, and a high gas-liquid ratio can be obtained in the flow channel even if the gas-liquid ratio is low outside the flow channel. Therefore, highly efficient gas-liquid reaction and gas dissolution are performed inside the gas-liquid pressure mixer.

Further, the gas-liquid pressurizing and mixing apparatus of the present invention is provided with an exhaust port at the upper part of the flow path for removing gas when the inflow of the gas-liquid mixed flow is stopped, and is added when the inflow of the gas-liquid mixed flow is stopped. This prevents the gas staying in the flow channel from expanding due to the pressure loss and blowing out from the flow channel. In order to check the state of the gas-liquid pressurizing mixer, an intermediate throttle having a larger diameter than the throttle on the outlet side is provided in the middle of the flow path, and the pressure behind it is measured to determine the emergency situation of the gas-liquid pressurizing mixer. Can be detected more accurately. Further, by adjusting a valve provided at the end of the branch flow path, exhaust gas and excess pressure in the flow path are adjusted.
