A multi-component fluid mixing device for mixing two or more fluids which can be used with an applicator tool, such as a spray gun. The mixing device is used with a removable cartridge that is pressure fitted into the body of the mixing device using an actuation mechanism that elevates a cartridge engagement base to create a fluid-tight seal.

A system, method, and apparatus for oxygenation of a source of water, to increase the dissolved oxygen content of water. Aspects of the present invention harnesses and directs the power of water flowing through the system to extract oxygen present in air, rather than relying on the injection of gas or using other mechanical means. The water oxygenator is formed as an elongate cylindrical tube having a water inlet at a first end, a water outlet at a second end, and an air inlet proximal to the first end. The elongate cylindrical tube has an outer sidewall defining a mixing chamber within an interior cavity of the water oxygenator. The mixing chamber includes a plurality of baffles that are disposed in a spaced apart relation along a longitudinal length of the interior cavity.

A rotary machine for acting on a process fluid includes an impeller, a shaft, a drive, a seal and a flush casing. The impeller acts on the process fluid and is mounted on the shaft. The drive is connected to the shaft and rotates the shaft and the impeller about an axial direction. The seal has a sealing element sealing the shaft during rotation of the shaft. The flush casing receives a flushing fluid for flushing the sealing element, and delimits an annular flush chamber extending about the sealing element. The flush casing includes a bushing surrounding the sealing element and delimits a radial leakage gap arranged between the sealing element and the bushing. The bushing delimits an axial leakage gap between the impeller and the bushing, and the width of the axial leakage gap in the axial direction is adjustable.

A system and method is provided for direct condensing steam heating of oil sands process slurry streams including viscous bitumen froth and tailings products streams. Slurry viscosities greater than that of water increase cavitation and vibration issues. High solids content exacerbate component erosions. Difficult, and competing, steam and slurry interactions are managed by steam nozzle arrangements and management of steam injection at sub-sonic velocities based on a ratio of the slurry back-pressure Pb and steam supply delivery pressure Po.

An eductor for mixing a diluent with a chemical. The educator includes an eductor body having a nozzle section with an inlet portion and an air gap portion, the inlet portion configured to couple to a diluent source and the air gap portion open to the atmosphere, and a venturi section coupled to the nozzle section. The nozzle section and venturi section may be connected by a swivel joint. The venturi section includes a venturi configured to couple to a chemical source for drawing chemical into the venturi with the flow of diluent through the venturi. A nozzle assembly positioned in the nozzle section of the eductor body. The nozzle assembly is selected from a plurality of nozzle assemblies each configured to be positioned in the nozzle section and operable with the eductor body, and each corresponding to a different volume flow rate through the eductor.

The invention generally relates to a mixing device. In certain embodiments, devices of the invention include a fluidic inlet, a fluidic outlet, and a chamber, the chamber being configured to produce a plurality of fluidic vortexes within the chamber.

A hydrodynamic cavitation generating device and a method, including: a wheel disc, being provided with a plurality of flow passages, an orifice plate is provided inside the flow passages, and a throat orifice is provided on the orifice plate; a driving mechanism, being connected to the wheel disc, and configured to drive a rotation of the wheel disc; and a water-inlet pipe, being arranged fixedly, fitting with a first side end face of the wheel disc, and may inject water into the flow passage when being aligned with the flow passage; the cavitation effect obtained by using the hydraulic cavitation generating device is better.

The invention relates to a tubing device for sterile media including a container for storing sterile media, a discharge port for discharging liquid sterile media, an inlet port for introducing fluid into the tubing device and a multiple-way-connector. The multiple-way-connector is connected to the container, the discharge port, the inlet port, and an apparatus for preparing, mixing and discharging a sterile medium for use with a tubing device, including a water inlet port for introducing water, a water outlet port configured to be connected to the inlet port of the tubing device, a fluid pump for conveying the fluid, the fluid pump is connected to the fluid inlet port and the water outlet port and a container support for supporting the container of the tubing device.

An exhaust mixer apparatus, emissions cleaning module, and a method of manufacturing the exhaust mixer apparatus is provided. The exhaust mixer apparatus comprises an exhaust conduit, a first exhaust mixer and a second exhaust mixer. The exhaust conduit is configured to extend in an elongate direction comprising an inlet and an outlet for transporting exhaust fluid. The first exhaust mixer comprises a plurality of elongate mixing blades each having a length extending in the elongate direction. Each elongate mixing blade comprising an outer edge extending in the elongate direction and blades are twisted along their lengths such that the outer edge is rotated about the elongate direction. The second exhaust mixer is configured to impart a swirl on an exhaust fluid and spaced apart from the first exhaust mixer in the exhaust conduit.
