  • Patent number: 10458446
    Abstract: Material flow amplifiers as disclosed herein overcome drawbacks associated with known adverse flow conditions (e.g., surface erosion and head losses) that arise from flow of certain types of materials (e.g., fluids, slurries, particulates, flowable aggregate, and the like) through a material flow conduit. Such material flow amplifiers provide for flow of flowable material within a flow passage of a material flow conduit (e.g., a portion of a pipeline, tubing or the like) to have a cyclonic flow (i.e., vortex or swirling) profile. Advantageously, the cyclonic flow profile centralizes flow toward the central portion of the flow passage, thereby reducing magnitude of laminar flow. Such cyclonic flow profile provides a variety of other advantages as compared to a parabolic flow profile (e.g., increased flow rate, reduce inner pipeline wear, more uniform inner pipe wear, reduction in energy consumption, reduced or eliminated slugging and the like).

  • Patent number: 9416604
    Abstract: A mixing device has an elongate shell, an inlet, an outlet and at least one shear orifice between the inlet and the outlet. A hydration passage is located between the shear orifice and the outlet. The hydration passage has a flow area greater than a total shear flow area of the shear orifice, greater than an inlet flow area of the inlet and greater than an outlet flow area of the outlet. During operation, a polymer is mixed in a fluid flow flowing to the intake of a positive displacement pump, which pumps the fluid through the mixing device and into an injection conduit leading into a well. The shear orifice produces high shear separation of molecules of the polymer. The hydration passage causes hydration under pressure of the various polymer molecules in addition to blending the various chemicals and/or gases with other components of the fluid flow stream.

By this characteristic, the fine particles do not contact with an inner wall of the cylindrical body, and therefore clogging does not occur in the cylindrical body. Moreover, the pressure around the center of the vortex flow becomes negative, and the fine particles are aspirated. Therefore, dust is hardly generated.

  • Patent number: 7281841
    Abstract: The invention relates to a mechanical device with no moving parts that homogeneously mixes two or more liquids or liquids and gases. It is possible with the device to totally saturate liquids with gas droplets of less than one micron. The device comprises an inlet for partially mixed components leading to a plurality of passageways converging axially into a chamber which has radial openings into another chamber defined by a conical member converging in the axial direction and having an opening at its apex to exit the mixed components, the components exiting the radial openings collide with the walls of the conical member producing shear and turbulence and subsequently spinning within the conical member and are then subjected to increased pressure in the axial direction by the converging wall of the conical member.

  • Patent number: 7175337
    Abstract: Liquid is supplied within a substantially vertical mixing chamber in a substantially tangential manner from a chamber top section, such that the liquid is deflected for rotatory motion against a chamber wall while advancing, in response to a pressure difference, downwards in the direction of a chamber longitudinal axis. Pulverous material is supplied by compressed air into the chamber (3) from the top section and into an air core (A) established by the liquid in rotatory motion, such that the pulverous material containing little air, and by being heavier than the air contained in the pulverous material and/or used for carrying the same, is driven in response to a centrifugal force into the liquid in rotatory motion, and the air separates towards the eddy center, and that the liquid containing pulverous material and the air supplied into the chamber, are discharged through an open bottom section of the chamber (3).

  • Patent number: 6758591
    Abstract: In one embodiment, a mixing device includes a nozzle that is disposed tangent to a wall of a chamber. Gas flowing from the nozzle rotates in the chamber forming a vortex. Another gas may be flown near a middle portion of the chamber, thereby uniformly mixing the two gases. In another embodiment, an evaporation and mixing device includes a nozzle configured to impart rotation to a gas flowing into a chamber. An injector flows a liquid material near a middle portion of the chamber, thereby mixing the gas and the liquid material. A heater may be employed to help evaporate the liquid material.
