Patent number: 5762687Abstract: The invention relates to a process for solution of a quantity of gas in a flowing quantity of liquid, in particular for solution of CO2 gas in beer, a flow of liquid and a flow of gas being combined and the gas in the liquid being dispersed, mixed with, and a part of it being mixed in the liquid. The object of the invention is to increase the amount of gas actually soluble in a liquid under certain conditions in comparison to prior art processes. In addition, the device for application of the process is to be simple in structure, cleanable in continuous flow (CIP-compatible), and its adaptation to specific practical requirements and its control are to be as simple as possible. From the process engineering viewpoint this is accomplished by guiding the gas/liquid mixture into curved paths, as a result of which separation into a bubblefree liquid flow (L1*) and a gas/liquid flow (G*/L2) to be recirculated.Type: GrantFiled: May 12, 1995Date of Patent: June 9, 1998Assignee: Otto Tuchenhagen GmbH & Co.

Patent number: 5218833Abstract: A process is disclosed for maintaining the temperature and humidity of a closed chamber within preferred ranges when contributions in water vapor and energy additions to the chamber from plants and humans vary over time. Enough water is evaporated into the air of the chamber such that when added to the water vapor added by transpiration a constant maximum rate of water vapor addition is maintained, thereby increasing air humidity and decreasing air temperature. A portion of warm moist air from the chamber is circulated to a water recovery heat exchanger module to remove additional sensible heat and to recover the amount of water evaporated in the chamber; cool dry air is returned to the chamber.Type: GrantFiled: March 11, 1992Date of Patent: June 15, 1993Assignee: Bend Research, Inc.Inventor: David D.

Patent number: 4287138Abstract: A method is disclosed for recovering and reclaiming heat from a source of relatively hot gases, which are preferably substantially vapor-saturated, by directly contacting the gases with a relatively cooler spray of liquid, such as water, in a heat exchange zone. The relatively warm liquid resulting from the contact of the sprayed cooler liquid with the vapor-saturated gases are collected in a receiver zone in the heat exchanger. This relatively warm liquid is then available for use. The hot gases which entered the heat exchanger will exit at a cooler temperature. They may be released to the atmosphere or returned to a process or room. The method is particularly suited for recovering heat from steam system condensate vents, dye fixation steamer exhausts, boiler exhaust stacks, and dry can enclosures such as those used in the textile and paper industry.Type: GrantFiled: March 5, 1980Date of Patent: September 1, 1981Inventor: Lynn A.

Patent number: 4207180Abstract: A method and an apparatus for promoting gas-liquid reaction in a reactor comprise pumping the reacting liquid to a predetermined height in a flow conduit. Gas is admitted to the liquid flow course to affect entraining gas in the flowing liquid and forming a gas-liquid mixture in the flow conduit. Said gas-liquid mixture is then guided to flow downwardly in a sustaintially vertical tube and subsequently discharged in a submerged eductor means for inducing a secondary circulating flow in the reactor. The circulating flow of the reactor liquid disperses the discharged gas homogeneously throughout the reactor and promotes a effective gas-liquid mass transfer.Type: GrantFiled: January 11, 1979Date of Patent: June 10, 1980Inventor: Shih-chih Chang

Patent number: 4166086Abstract: An aerator device for maintaining a high level of oxygen in live bait storage containers is disclosed. The aerator device comprises a cover for the container on which is mounted a suitable drive motor. The shaft of the motor extends downwardly through the cover and carries at its lower end an impeller which is driven by the motor at a high rate of speed to vigorously stir and aerate the water in the container. The upper portion of the shaft is enclosed by a housing which depends from the cover and extends down below the water level in the container. The lower end of the shaft and the impeller are surrounded by a relatively stiff screen having openings large enough to allow the free circulation of water, but small enough to prevent bait from reaching the impeller.
