The present invention provides a system for enriching a flowing liquid with a dissolved gas inside a conduit. The system comprises two or more capillaries, each capillary delivering a stream of a gas-enriched liquid to the flowing liquid. The first ends of the capillaries are positioned to form an intersecting angle with respect to the effluent streams such that these streams of gas-enriched liquid collide with each other upon exit from the first ends of the capillaries, effecting localized convective mixing within the larger liquid conduit before these gas-enriched streams are able to come into close contact with the boundary surfaces of the conduit, whereby the gas-enriched liquid mixes with the flowing liquid to form a gas-enriched flowing liquid. In the preferred embodiment, no observable bubbles are formed in the gas-enriched flowing liquid. Methods of making and using such system are also provided.

The invention relates to the food industry. A method of saturating a beverage with CO2 comprises supplying the liquid and the gas under pressure, increasing the mass transfer surface, intensively mixing the components in a chamber, and subsequently feeding them into a storage tank. The mass transfer surface is increased abruptly prior to mixing by converting the liquid to a moist saturated vapor state, and the vapor-gas mixture is condensed before feeding into the storage tank. Also described is a device for saturating a beverage with CO2, which device is in the form of a water-air ejector.

A washing machine that includes a cabinet; an outer basket in the cabinet and configured to accommodate wash water; an inner basket in the outer basket and configured to accommodate laundry; a water supply valve unit in the cabinet and connected to an external water supply source, configured to receive wash water; and a micro-bubble generator configured to receive the wash water from the water supply valve unit, generate micro-bubbles, and supply the micro-bubbles to a washing space. The micro-bubble generator includes a dissolving unit configured to mix or dissolve gas into the wash water from the water supply valve unit. The dissolving unit includes: a water supply line connection connected indirectly to the water supply valve unit, configured to introduce the wash water; a supply hole providing a path in which gas is introduced into a dissolution space; and a dissolved water drain portion discharging the wash water in which gas is mixed or dissolved.

The description relates to methods and apparatus that enable the efficient introduction of gases like air, oxygen and ozone into aqueous liquids. Gases are introduced into liquids for making that gas chemically or biologically available at a minimum energy expenditure. Impinging jets of liquid are directed into a pressurized saturation vessel having a gas-filled headspace and a saturation zone below the surface of the liquid at a velocity sufficient to create a turbulent impact and plunge zone. The resulting turbulence and mixing of gas and liquid in that zone under pressure, causes the gas to be driven into the liquid in the vessel and breaks up the gas and the liquid into a churning flow and creates a large number of bubbles. The resulting gas-enriched liquid is discharged from the vessel at an outlet to ensure a minimum of bubbles in the gas-enriched liquid.

A fine bubble generation device in one aspect of the present disclosure is a device that generates fine bubbles in a liquid by causing the liquid to pass through a porous element having many pores. In the fine bubble generation device, a differential pressure is applied between first and second sides of the element, and, by the applied differential pressure, the liquid disposed on the first side of the element is passed through the element and is jetted toward the second side to thereby generate fine bubbles. In this fine bubble generation device, the flow speed of the liquid during passage through the element is 0.009769 [m/s] or higher. The fine bubbles can thereby be generated efficiently.

A beverage aerator includes a housing, a pump-motor assembly, an uptake tube, and a spray nozzle. The housing is sized to removably seat on a neck of a decanting vessel. The pump-motor assembly is positioned within the housing, and has a pump inlet and a pump outlet. The uptake tube is fluidly coupled to the pump inlet upstream of the pump inlet. The uptake tube has a tube inlet end located below the housing. The spray nozzle is fluidly coupled to the pump outlet downstream of the pump outlet. The spray nozzle is located below the pump-motor assembly and oriented to have a laterally-outward discharge direction.

A system for dissolving gases in water comprises a mixing chamber that holds gas and a container in fluid communication with the mixing chamber. In operation, the mixing chamber is flooded to purge the ambient air. A gas delivery system introduces gas into the mixing chamber to push the water out. A pump then pumps temperature and salinity-treated water into the mixing chamber, and a distributor sprays or disperses the water into the mixing chamber. An optional impingement plate and/or mixing medium trap gas bubbles and hold gas-saturated water within the mixing chamber. This produces a volume of substantially bubble-free, highly-saturated gas-infused water that is then released into the container to mix with the water contained therein. This system can be incorporated in aquariums, ice chests, buckets, and live wells found on boats, kayaks, trucks, and other transports.

This invention provides a continuous liquid phase type wet exhaust gas treatment method for removing sulfur oxides from exhaust gas and collecting it as gypsum, which method is simple and humidifying liquid is uniformly sprayed into exhaust gas with it. The method is characterized in that humidifying liquid is injected downwardly in a region where exhaust gas flows vertically downwardly.
