The present disclosure includes mixing apparatuses comprising a pipe having an internal channel having a convergent frustoconical portion, and a divergent portion. The divergent portion may comprise a divergent frustoconical portion and an annular, concave curved portion. A plurality of injection ports may be spaced circumferentially in the convergent frustoconical portion and communicate a liquid into internal channel. The plurality of injection ports may define an opening in the internal channel having a first dimension in a circumferential direction that is larger than a second dimension in a longitudinal direction. The injection mixer may be configured to mix a first fluid flowing through the pipe with the second fluid to form a fully homogenous, dispersed fluid mixture.

A beverage container may comprise a beverage container lid assembly comprising at least one concentrate well to hold a concentrate vessel, a concentrate vessel retainer for each concentrate well to secure the concentrate vessel in the concentrate well, a feed line for each concentrate well comprising a feed line needle to puncture the concentrate vessel in the at least one concentrate well, a Venturi mixer in fluid communication with each feed line, a mixing valve in fluid communication with each feed line, wherein fluid flows from the concentrate vessel to the Venturi mixer when the mixing valve is open and the concentrate vessel is punctured by the feed line needle. Methods of using the beverage container and beverage container lid assembly are also described.

A system and method for delivering a treatment fluid to a wellbore by emulsifying the treatment fluid with a continuous fluid in a flowline. The treatment and continuous fluids are combined in a mixer that is separate from containers that retain the fluids. In an example where the mixer is a venturi, the continuous fluid flows into an inlet on an entrance end of the venturi, and the treatment fluid flows into an inlet that is at a flow restriction in the venturi. The continuous fluid experiences a localized decrease in pressure at the restriction, which is due to a localized increase in flow rate at the restriction. The pressure decrease induces the treatment fluid into the venturi, where the treatment fluid is dispersed into droplets within the continuous fluid, and that forms a treatment emulsion. The treatment fluid escapes from within the treatment emulsion when in the wellbore.

An apparatus for mixing a liquid and a substance, including a housing with a liquid inlet and a substance inlet to a mixing chamber, an outlet for a mixture of liquid and substance, and a flow restrictor arranged in the housing, between the liquid inlet and the mixing chamber. The flow restrictor is controllable to switch between a first position providing a first through flow area configured to create a Venturi effect such that a flow of the liquid draws the substance into the mixing chamber, and a second position providing a second through flow area that is larger than the first through flow area to thereby decrease a pressure drop caused by the flow restrictor.

A pressure washer includes a prime mover, a water pump, the water pump including a pump inlet for receiving fluid from a fluid source and a pump outlet for supplying a pressurized primary fluid, a jet pump including a primary fluid inlet fluidly coupled to the pump outlet, a secondary fluid inlet, and a fluid outlet, and a spray gun configured to be fluidly coupled to the fluid outlet of the jet pump, the spray gun including a spray gun outlet having a variable effective flow area. Wherein, in operation, in a high pressure operating mode, the pressurized primary fluid flows through the jet pump and exits through the fluid outlet of the jet pump, and in a high flow operating mode, the pressurized primary fluid flows through the jet pump and entrains a secondary fluid supplied through the secondary fluid inlet, resulting in a combined fluid flow.

A configuration for water purification undergoes the water supply step of taking in treatment water through a water suction port and pressure-feeding the treatment water, the air supply step of taking in air through an air suction port and supplying the air, the oxygen amount increasing step of pressurizing the air supplied at the air supply step to increase the total amount of oxygen, the ionization step of ionizing the pressurized air subjected to the oxygen amount increasing step, the mixing step of obtaining gas-liquid mixing fluid subjected to first fine air bubble formation by spraying the air into the flow of treatment water, and the accelerated spraying step of performing second fine air bubble formation by accelerating a flow velocity by a narrowed-diameter portion provided at a spray nozzle when the gas-liquid mixing fluid obtained through the mixing step is sprayed into the treatment water.

A gas dissolving system using double mixers to generate a higher gas concentration in liquid is disclosed. The gas dissolving system includes two gas mixers, a degassing device, pressure valves, a pressure sensor, and a pump. Liquid flows through mixers to entrain gas therein, and it thus contains dissolved gas and undissolved gas. The liquid subsequently flows into the degassing device so that undissolved gas is released to the outside environment, and dissolved gas remains in the liquid. The liquid with dissolved gas combines with raw liquid and is diluted so that it becomes liquid with a desired gas concentration as the output. A high gas concentration of liquid is obtained after more cycles of fluid flow through the mixers to dissolve gas without combining raw liquid.

A Venturi device for introducing a second fluid into a first fluid includes a T-joint, a converging component, and a diverging component. The T-joint component includes a first elongated tube extending along a first direction and a second elongated tube extending along a second direction being perpendicular to the first direction. The converging component is shaped and dimensioned to slip fit within a first through-opening of the first elongated tube through a first inlet port and has a cross-section that decreases along the first direction from the first inlet port to an inner section of the first though-opening. The diverging component is shaped and dimensioned to slip fit within the first through-opening of the first elongated tube through an outlet port and has a cross-section that increases along the first direction from the inner section of the first though-opening to the outlet port. The converging component is coaxially aligned with the diverging component along the first direction.

The system may be a device that allows for mixture of an additive to a substance in a line of flow. The system may include a hydration pack with a reservoir that may contain a first substance, such as water. The system may include a cartridge with an additive that is mixed to the line of flow through a Venturi which may include a rolling seal that is manipulated with a dial a user manipulates to adjust the amount of additive added to the line of flow. The mixed liquid may then be accessed through a hose from the system to a mouth piece. The system may be modular to allow a user to replace the cartridge by disengaging a first component and a second component of the system through a buckling mechanism and replacing the cartridge within the second component. The cartridges may be reusable, recyclable or disposable.
