摘要： A method and apparatus for dissolving a gas into a fluid which may contain at least one other dissolved gas. The apparatus includes an inlet tube for receipt of the fluid from a container containing the fluid. A gas inlet is operably connected to the inlet tube for the introduction of gas into the fluid. The mixture of gas and fluid is introduced into a gas transfer device via the inlet tube. The gas transfer device is positioned below the surface of the fluid in the container so that the gas transfer device is hydrostatically pressurized in order to increase the rate and concentration at which the gas is dissolved into the fluid. The gas and fluid mixture is allowed to flow downward through the gas transfer device such that bubbles of gas are dissolved in the fluid. The fluid having the gas dissolved therein enters an outlet means positioned within the gas transfer device. The fluid having the gas dissolved therein flows upward through the outlet means and is released from the gas transfer device while the bubbles of gas which are not dissolved in the fluid are retained in the gas transfer device.

摘要： A method and apparatus for dissolving an gas into a fluid which may contain at least one dissolved gas. In one embodiment, the apparatus includes a first vertically oriented tube defining a first inner space therein and having open upper and bottom ends. The apparatus also includes a second vertically oriented tube of diameter larger than the first tube and concentrically oriented about the first tube. The space between the first and second tubes is referred to as the second inner space. For introduction of the gas, the apparatus includes an inlet into the second inner space. The appartus includes an acceleration device for accelerating the flow of fluid through the second inner space. The acceleration device is placed above the bubble swarm. Further, the apparatus includes a helix-shaped bubble harvester located below the bubble swarm. The harvester removes fugitive (undissolved) bubbles from the fluid flow and returns them to the bubble swarm to increase the probability that those bubbles will be dissolved into the fluid. During operation, fluid is accelerated downward through the second inner space to maintain two phase flow in the bubble swarm. The harvester removes fugitive bubbles from the fluid leaving the bubble swarm and returns them to the bubble swarm to enhance the absorption rate and efficiency. In another embodiment of the invention, at least one gas initially dissolved into the fluid and then stripped by the reduced partial pressure in the bubble swarm is allowed to leave the apparatus through a vent. The present invention operates with hydrostatic pressure applications and in applications using externally supplied oxygen. It is inexpensive to produce, install, operate and maintain, while being capable of producing a significant amount of dissolved gas with a high absorption efficiency and low energy consumption. The apparatus and method are also suitable for a multitude of applications.

摘要： A method and apparatus for dissolving a gas into a fluid which may contain at least one dissolved gas. The apparatus comprises a conventional U-tube oxygenator which includes a U-tube member having an inlet for the introduction of the fluid and the gas to be dissolved into the fluid, and an outlet. The fluid is housed in the U-tube member. The apparatus further comprises a helix-shaped bubble harvestor located proximate the bottom of the inlet side of the U-tube member. The helix-shaped bubble harvestor removes fugitive (undissolved) gas bubbles from the fluid flow and returns them to the bubble swarm located above the helix-shaped bubble harvester. The resulting fluid, which contains a high concentration of dissolved gas, exits the outlet of the U-tube member.
