  • Patent number: 10322383
    Abstract: A liquid treatment apparatus (10) for processing a liquid includes an inlet nozzle (12) having an orifice (16) for directing a flow of liquid through the orifice (16) to define a fluid jet, and a concial diffuser (18) including a tip (20), a base portion (22), and a curved surface (26) therebetween. The conical diffuser (18) is generally aligned with the orifice (16) such that the fluid jet impacts upon the tip (20) of the conical diffuser (18). Moreover, the curvature of the curved surface (26) is selected to maintain a substantially constant Froude number of the liquid along the conical diffuser (18).

  • Patent number: 9932246
    Abstract: A liquid treatment apparatus includes a supply chamber for receiving a fluid, a discharge chamber for discharging the fluid, and a cavitation generating chamber extending from the supply chamber to the discharge chamber. The cavitation generating chamber is operable to generate cavitation bubbles. A method of treating a liquid comprises directing a fluid from a supply chamber into a cavitation generating chamber by constricting the fluid through an orifice, wherein the orifice has a cross dimension that is substantially less than a cross dimension of the supply chamber, such that a fluid jet is formed. The method further includes allowing the fluid jet to expand downstream of the orifice such that the velocity of the fluid is reduced so that the jet axial velocity head at the chamber outlet is less than the difference between the static pressure within the discharge chamber and the vapor pressure of the fluid. The method also includes discharging the fluid into a discharge chamber via a chamber outlet.

  • Patent number: 8753505
    Abstract: An apparatus for treating a liquid includes a first flow generator having an outlet for generating a first flow stream and a reaction chamber positioned in proximity to the outlet of the first flow generator and having a cavity adapted to receive the first flow stream from the first flow generator and reverse its direction within the confined space of the cavity. The flow generator may be a cavitation generator for producing multiple cavitation bubbles in the first slow stream, or a nozzle for generating a flow stream devoid of cavitation bubbles. A method for treating a liquid includes directing the liquid into a first flow generator configured to generate a first flow stream of the liquid, and directing the first flow stream from the first flow generator into a cavity of a reaction chamber.

  • Publication number: 20080277264
    Abstract: A system and method is provided which includes using a liquid treatment apparatus, which is equipped with cyclonettes, for example, to subject a liquid medium processing stream in an alcohol production process to hydraulic cavitation, i.e., to shear under vacuum, at one or more locations. The liquid treatment apparatus, in one embodiment, is directed to the formation of a central axial jet and a vacuum chamber that can be sealed by the exiting jet. Cavitation is generated by directing a high velocity jet of liquid medium processing stream through a volume of vapor under a vacuum created in the chamber through which the jet travels. This can reduce the production cost of alcohol, such as ethanol, by improving alcohol yield per bushel, among other benefits. In one embodiment, the alcohol production process is a dry grind process, a modified dry grind process, or a wet mill process. In one embodiment the alcohol production process utilizes grain as a starting material.

  • Patent number: 4348955
    Abstract: In a blow-molded, cylindrical plastic container for explosives adapted for end-to-end coupling with like containers, an improvement is provided in the sealing of the container at the exposed explosives end. The improvement comprises a section of reduced diameter in the portion of the container immediately beyond the point of connection of a like container. The section of reduced diameter is adapted to receive therein a resilient plastic, disc-like sealing member in fluid-tight engagement. The seal prevents contamination of the explosive yet yields upon the pressure exerted by an adjacent, connected container.
