A mixing apparatus includes: a driving device configured to drive first liquid to flow into first transfer chamber and to drive second liquid to flow into second transfer chamber, a first transfer chamber configured to store inflowed first liquid, and a second transfer chamber configured to store inflowed second liquid; a premixing chamber communicating with liquid outlet of first transfer chamber and liquid outlet of second transfer chamber; and a monitor configured to monitor volume of liquid in first transfer chamber and volume of liquid in second transfer chamber, close liquid inlet of first transfer chamber and control first liquid to flow into premixing chamber when volume of first liquid is equal to first value, and close liquid inlet of second transfer chamber and control second liquid to flow into premixing chamber when volume of second liquid is equal to second value.

A fine bubble generator which is an ultrafine bubble generator includes a side wall whose inner face is cylindrical, and closing walls closing both ends of the side wall, respectively, with a gas-liquid discharge port in one of the closing walls, wherein a fluid inlet port is provided closer to the gas-liquid discharge port than is a midpoint between both closing walls, and the fluid inlet port penetrates the side wall in a tangential direction of the inner face of the side wall, wherein a spiral groove is formed in the inner face of side wall, and wherein the spiral groove has an angle of inclination of 1° to 10°.

A method and system for forming a liquid mixture utilizes a mixing tank with a tank inlet oriented and configured to create a swirling liquid flow that forms a vortex within the tank. A portion of the swirling liquid is discharged through an outlet formed by an opening in a lower wall of the tank. At least a portion of the opening is offset to one side of a central axis of the lower wall. Liquid is circulated and reintroduced into the tank inlet. A material to be mixed is introduced into the swirling liquid flow within the tank interior to form a liquid mixture.

A vortex flow inducer has inducer body with an interior end, an outer end and a length extending there between, and a longitudinal axis extending between the interior and the outer ends. A flow passage extends between the interior and outer ends of the inducer body. The flow passage has an inlet at the outer end and an exit at the interior end. The flow passage is swept latterly toward a side of the inducer body in a direction from the outer end toward the interior end such that the exit is latterly offset from the longitudinal axis. The interior end of the inducer body has a concave curvature. The swept flow passage and the curved interior end induce a vortex flow in a fluid flowing through the flow passage as it exits the flow passage and into a flow passage of a conduit the that extends at an angle relative to the longitudinal axis of the inducer body.

There is provided an ammonia gas removal system, including a fine bubble generation device which is configured to receive at least a portion of scrubber process water from a storage tank, and to generate fine bubbles containing carbon dioxide gas in the received scrubber process water, the storage tank being configured to store the scrubber process water to be provided to a gas scrubber, the gas scrubber being configured to spray the process water onto ammonia-containing gas.

A gas mixing device includes: a cylindrical portion including an upper surface which is closed; a gas outflow passage formed in a central portion of a bottom surface of the cylindrical portion, and extends downward; a plurality of gas stream guide walls disposed to be spaced apart from each other in a circumferential direction along an edge of an opening formed by the gas outflow passage in the bottom surface, and installed to be rotationally symmetrical to a center of the cylindrical portion, the gas stream guide walls protruding toward the upper surface; and a gas inlet part installed between the gas stream guide walls and an inner peripheral surface of the cylindrical portion, and into which a gas to be mixed flows.

An apparatus for processing a substrate includes a mixing nozzle having a mixing space that is shaped as an inverted cone, the mixing nozzle including a first inlet, a second inlet and an outlet installed at the mixing space; a first chemical supply unit connected to the first inlet; a second chemical supply unit connected to the second inlet; and a supply tank connected to the outlet, wherein the first chemical supply unit is configured to supply a first chemical solution to the mixing space through the first inlet, the second chemical supply unit is configured to supply a second chemical solution to the mixing space through the second inlet, and the supply tank is supplied with, through the outlet, a solution mixture that is formed of the first chemical solution and the second chemical solution after being mixed in the mixing space.

A cavitation device and method for using the same is useful for cavitationally treating fluids by generation of hydrodynamic cavitation in the fluid followed by the subsequent collapse of cavitation bubbles. The passage of fluid through slot openings in a cylindrical insert mounted in a housing provides fluid jets in an annular cavity to induce hydrodynamic cavitation of the fluid. Fluid is discharged from the annular cavity into a downstream portion of the housing to collapse cavitation bubbles under static pressure.

A matter displacement and mixing system having a mixing chamber for material to enter, and a vortex aperture that directs air into the mixing chamber at either a high velocity for violent shearing or lower velocity for gentle mixing. This would depend on the shape of the vortex aperture, or the pressure.

A piping manifold that combines multiple solids fluidizers with a common motive fluid connection and a common slurry discharge connection. The manifold utilizes flexible pipe materials to connect the individual fluidizer feed and discharge connections to a distribution and a collection hub that are combined into a single structure with a common dividing plate between the distribution and collection chambers. An adjustable support structure that allows adjustable positioning of the individual fluidizers without customized design, manufacturing or modification of the manifold.
