A flow conditioning device for conditioning a wet gas stream having a plurality of liquid droplets and a gas flow is presented. The flow conditioning device includes a first segment including a first convergent section configured to break the plurality of liquid droplets from a first size to a second size. Further, the flow conditioning device includes a second segment coupled to the first segment and including a second convergent section configured to break the plurality of liquid droplets from the second size to a third size.

Provided is an ultrafine bubble generating apparatus capable, when generating nanobubbles in a liquid, of appropriately mixing a gas into a liquid ejected from a liquid ejector. The ultrafine bubble generating apparatus includes a liquid ejector for ejecting a liquid, a gas mixer for pressurizing and mixing a gas into the liquid ejected from the liquid ejector, and an ultrafine bubble generator for generating nanobubbles in the liquid by passing the liquid with intermixed gas therethrough. Between the liquid ejector and the ultrafine bubble generator, the gas mixer pressurizes and mixes the gas into the liquid, which is flowing in a pressurized state toward the ultrafine bubble generator.

An apparatus configured to generate generating water comprising nano bubbles of molecular hydrogen on demand. The apparatus is connected to a water supply with a valve and comprises a pump which supplies pressurized water to a venturi gas liquid mixer that also receives a supply of Hydrogen gas. The mixed hydrogen gas/water steam is provided to a nano bubble generating apparatus that uses cavitation to generate nano bubbles of Hydrogen in the water. The Hydrogen nano bubbles have diameters of less than 200 nm and a concentration of up to 1.2 ppm. Further the concentration remains with 85% of the output concentration for at least 12 hours.

A fluid supply pipe according to an embodiment of the invention includes a first internal structure, a second internal structure, and a pipe body configured to house the first internal structure and the second internal structure, and the pipe body has an inlet and an outlet. The first internal structure includes a head portion comprising a plurality of spiral vanes, and a body portion positioned downstream from the head portion and comprising a plurality of protrusions on its outer circumferential surface. The second internal structure formed in a hollow shaft shape includes a head portion comprising a plurality of spiral vanes, and a body portion positioned downstream from the head portion and comprising a plurality of protrusions on its outer circumferential surface. At least a part of the first internal structure is housed in the hollow of the second internal structure.

Homogenizing valve (1) at high pressure, particularly for application to fibrous fluids, comprising: a valve body (2); a passage head (15) integrally joined to the valve body (2); an assembled organ (27) formed of two pistons (5, 6) and a striking head (16), which is axially mobile inside a through hole of the valve body (2), so that the striking head (16) defines with the passage head (15) an interspace (18) of passage of the fluid, the assembled organ (27) being rotatable thanks to the lower cogged profile which engages in a cogged tool (20).

A homogenization device having an inlet valve, a flow-through chamber and a discharge valve. A baffle element reciprocatingly moves between an upstream portion and a downstream portion of the flow-through chamber. When the baffle element moves downstream, the inlet valve opens and liquid is admitted into the upstream portion. When the baffle element moves upstream, the inlet valve closes, the liquid in the upstream portion is pressurized and forced to flow downstream through a gap or local constriction between the outer perimeter of the baffle element and the inner surface of the chamber, causing cavitation bubbles to form and collapse.

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.
