Abstract:     An apparatus for dissolving a gas, such as oxygen, into a liquid, such as water, having a low concentration of that gas. The apparatus has an inlet, an outlet and a central region therebetween and has walls defining an interior adapted for dissolving the gas in the liquid. The apparatus also has a gas injecting means adapted for maximizing a gas-liquid interface and promoting contact between the gas and the liquid, thereby maximizing the concentration of the gas in the liquid. The apparatus is useful for modifying the liquid for a specific purpose, such as for developing a culture medium. The apparatus can have different internal configurations, depending on the degree of gas linkage and retention required.

First Claim:
Show all 12 claims
What is claimed is:     1. A system for dissolving a gas delivered from a gas supply in a liquid which moves through the system, the liquid having the characteristic of being low in concentration of the gas upon entry into the system, the system comprising:
  • a substantially closed chamber having an inlet through which the liquid flows, an outlet from which the liquid leaves the system, and a central region therebetween, said central region having walls defining an interior adapted for dissolving the gas in the liquid and having one or moore orifices for introducing the gas into said chamber; and
  • a venturi including a pipe section and a horn, said venturi having a venturi inlet into which the liquid flows and a venturi outlet from which the liquid flows, said horn having a horn inlet into which the liquid flows and a horn outlet from which the liquid flows, said venturi defining between said venturi inlet and said venturi outlet a passage which initially converges to a minimum spacing in the direction of liquid flow and thereafter widens more slowly, thereby creating a low pressure region in the path of liquid flow and permitting the liquid to siphon the gas from said pipe section and displace the gas into the liquid at high velocity from the incoming gas flow in the form of minute bubbles, the horn being in fluid communication with said pipe section and being positioned within the venturi such that said horn inlet is proximate to said low pressure region, said venturi maximizing a gas-liquid interface and promoting contact between the gas and the liquid, the horn optimizing the displacement of the gas into the liquid.
