The multi-component fluid mixing devices include one or both of a serpentine flow path and an attachment point decoupled from an inlet of the multi-component fluid mixing devices. The method of use includes switching between multi-component fluid mixing devices with different length flow paths, while retaining a constant position of the outlet of the multi-component fluid mixing devices. A manufacturing method includes fusing two halves of a multi-component fluid mixing device together with mixing elements in a serpentine flow path captured in a mixer wall formed between the two halves of the multi-component fluid mixing device.

A static mixer is provided. The static mixer includes a plurality of static mixer elements. Each static mixer element includes a core extending axially along a longitudinal axis between a first end and a second end. Each static mixer element includes at least one blade around an outside of the core. At least a first one of the plurality of static mixer elements includes a first keying feature. At least a second one of the plurality of static mixer elements including a second keying feature configured to engage the first keying feature to prevent relative rotation between the first one of the plurality of static mixer elements and the second one of the plurality of static mixer elements about the longitudinal axes of the first one and the second one of the plurality of static mixer elements. Methods of forming the static mixer are also provided.

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 invention provides a microdroplet- or bubble-producing device that does not require separate through-holes for different liquid droplet/air bubble-producing flow channels. The droplet-producing flow channels are configured in a three-dimensional manner unlike in a conventional device where they are configured in a two-dimensional plane, and therefore the flow channels can be provided in a more high-density configuration than the prior art. In the microdroplet/bubble-producing device comprising slit(s) and the row of the plurality of microflow channels, the slit(s) is/are a continuous phase supply slit, a dispersion phase supply slit and a discharge slit, the plurality of microflow channels are configured so that the ends of the slit(s) and the two supply ports on both sides or the supply port and discharge port on either side are mutually connected, and at the sites of connection between the microflow channels and the slit(s), the dispersion phase undergoes shear with the continuous phase flow as the driving force, producing droplets or air bubbles of the dispersion phase, which are recovered from the discharge port.

A device for dissolving a gas in a liquid is provided, the device comprising a device body, the device body comprising a liquid inlet; a liquid outlet; a plurality of substantially conical dissolving chambers located between the liquid inlet and the liquid outlet. The device may comprise a plurality of chamber connectors of or connected with the dissolving chambers. Each of the plurality of conical dissolving chambers may comprise a wider end towards the liquid outlet, the wider end comprising a chamber outlet for flow of liquid out of the dissolving chamber; and a narrower end towards the liquid inlet, the narrower end comprising a chamber inlet for flow of liquid into the dissolving chamber. The plurality of chamber connectors may define a substantially longitudinally straight passage extending through the plurality of dissolving chambers. Also provided is a related method of dissolving a gas in a liquid.

A container for two or more viscous materials is provided that contains a reservoir, one or more mixing tube(s) and frame or shield, with one or more apertures arranged within the mixing tube. The container can include a frame and a first and second polymeric film joined to a first and, respectively second surface of the frame by one or more adhesive or seal seams.

A polymer activation assembly is provided for separating monomer from the oil in which it is suspended in a polymer forming suspension and mixing the monomer with water supplied from another stream. The supply water is supplied through a primary fluid channel extending through the activation assembly and which transitions to a relatively wide rectangular activation channel. A secondary fluid inlet is formed in a side of the activation assembly for injection of the polymer forming suspension therein. A nozzle section of the secondary fluid inlet is formed between an initial section of the inlet and the activation channel. The nozzle section is generally rectangular in cross section and relatively shallow. The distal end of the nozzle section has a width that approximates the width of the activation channel. The nozzle section angles at an acute angle toward the outlet.

A micromixer includes: a first channel plate where a first channel and a plurality of first branch channels are each formed by a non-through groove in a front surface, and a first confluence channel is formed by a non-through groove in a rear surface, and includes a first communication channel that communicates the first branch channels with the first confluence channel; a first lid plate that covers the front surface; a second channel plate where a second confluence channel is formed by a non-through groove in the front surface, and a second channel and a plurality of second branch each formed by a non-through groove in the rear surface, and includes a second communication channel that communicates the second branch channels with the second confluence channel; and a second lid plate that covers the rear surface of the second channel plate.

The invention provides a mixing apparatus. The mixing apparatus includes a first container, wherein the first container comprises: a first port; and a mixing chamber. The mixing apparatus further includes a second container, wherein the second container is adapted to receive the first container, and a seal disposed between the first container and the second container.
