Abstract
System and apparatus to accelerate solution of gas into liquid. The system includes an aspirating injector to bring the gas into the pressurized system, a collider, a reactor, and an optional gas/liquid separator. The collider and reactor provide for prompt renewal of the interface in the bubble with the liquid as the consequence of abrupt changes of direction of flow.
Claims20
A system for accelerating the solution of treatment gas into a liquid stream, said system being adapted to receive and maintain said stream under pressure, said system comprising:
- an aspirating injector comprising a body having an axial passage, a converging section, a throat section and a diverging section in said passage in that order, an injector port through said body entering said throat section and adapted to receive treatment gas to be dissolved in said liquid stream, said passage having an inlet port to receive said stream, and an outlet port;
- a collider and a reactor, each having an inlet port and an outlet port, the inlet port of one of them being connected to the outlet port of the injector, its outlet port connected to the inlet port of the other and;
- a fluid release receiving said stream from said last mentioned outlet port for releasing the treated stream from the system while maintaining the system under pressure:
- said collider comprising a body forming a chamber, a pair of nozzles opposing one another, said stream being divided so a portion flows through each said nozzle with their streams flowing toward and meeting one another in said chamber, said body having an outlet port exiting the chamber;
- said outlet comprising the exit for all of the stream which entered said chamber.

A system for accelerating the solution of treatment gas into a liquid stream, said system being adapted to receive and maintain said stream under pressure, said system comprising:
- an aspirating injector comprising a body having an axial passage, a converging section, a throat section and a diverging suction in said passage in that order, an injector port through said body entering said throat section and adapted to receive treatment gas to be dissolved in said liquid stream, said passage having an inlet port to receive said stream, and an outlet port;
- a collider comprising a body forming a chamber having an inlet port and an outlet port, said inlet port being connected to the outlet port of the injector, its outlet port being connected to a fluid release receiving said stream from said last mentioned outlet port for releasing the treated stream from the system while maintaining the system under pressure;
- said collider comprising a body forming a chamber, a pair of nozzles opposing one another, said stream being divided so a portion flows through each said nozzle with their streams flowing toward and meeting one another in said chamber, said body having an outlet port exiting the chamber, said outlet comprising the exit for all of the stream which entered said chamber.
A collider receptive of two streams of a gas/liquid stream to accelerate the solution of the gas into the liquid, said collider comprising:
- a body forming a chamber, pair of nozzles opposing one another, said stream being divided so a portion flows through each said nozzle with their streams flowing toward and meeting one another in said chamber, said body having an outlet port exiting the chamber, each of said nozzles includes a converging section, and twisting vanes in said converging section whereby to impart a rotary motion to the outer region of the stream as it flows through the nozzle.
A reactor receptive of a stream of liquid and bubbles of treatment gas, for accelerating the solution of said gas in said liquid, said reactor comprising:
- a body having a central axis with an internal cylindrical wall forming an axial internal cylinder, its said inlet port adapted to receive said stream, and its said outlet port adapted to discharge said stream with an increased dissolved amount of said treatment gas therein, said inlet port and said outlet port being centrally located on said central axis;
- a nozzle in said inlet port directing said stream axially into said cylinder;
- a partial barrier extending laterally across said cylinder dividing said cylinder onto a first chamber and a second chamber, said barrier having an upstream face facing into said first chamber and axially facing said nozzle, and a downstream face facing into said second chamber and facing said outlet port;
- said upstream face having a concave circular first reflecting surface centered on said central axis and facing said nozzle, the radius of said reflecting surface being smaller than the internal radius of said internal cylindrical wall;
- a plurality of axially extending arcuate blades, each having an outer wall closely fitting to said internal cylindrical wall, a dimension of radial thickness, and an inner wall concentric with its said outer wall, said blades having axially-extending side walls, said blades being angularly spaced from one another to provide an equal number of axial slots between them;
- a cove surface circularly surrounding said first nozzle, extending to said inner walls of the blades and to their intersections with said slots, whereby said stream discharges from said nozzle so a major portion of it strikes said reflecting surface, which reverses a major portion of the flow to the cove surface which in turn reflects a major portion of said flow toward said barrier along said blades and in said slots, said partial barrier being pierced between with slots between said slots to provide for flow from said first chamber into said second chamber, thereby to pass said flow from the first chamber into said second chamber, said outlet port discharging from said second chamber.
