A micro bubble generation method and generation device. The micro bubble generation method includes: passing a gas through a microporous material, the gas forming micro bubbles at an interface between the microporous material and liquid, the bubbles being adsorbed on the surface of the microporous material; impacting the micro bubbles adsorbed on the microporous material by relative motion of the microporous material and the liquid, such that the micro bubbles detach from the microporous material and enter into the liquid. The micro bubble generation device includes a gas accommodating chamber (1) disposed below the liquid surface, and a gas transmission pipeline (3). A microporous material layer (2) is arranged around the periphery of the gas accommodating chamber (1). The gas in the gas accommodating chamber (1) passes through the microporous material layer (2) by gas pressure to form micro bubbles on the outer surface thereof. The microporous material layer (2) moves and/or the liquid outside the microporous material layer (2) moves to cut the micro bubbles.

Initial liquid containing fine bubbles is produced by mixing water and air (step S11). Fine bubbles have diameters of less than 1 m. The density of bubbles in the initial liquid is measured (step S13), and when the measured density is less than a target density (step S14), the initial liquid is heated and reduced in pressure so that the liquid is vaporized (step S15). As a volume of the liquid decreases, the density of fine bubbles increases, and high-density fine bubble-containing liquid is easily obtained. Alternatively, by increasing the density of fine bubbles in the initial liquid with using a filter that does not pass all fine bubbles, high-density fine bubble-containing liquid is easily acquired (step S15). When the density of bubbles in the initial liquid is greater than the target density, the initial liquid is diluted (step S16).

A new method for generating micro-nano bubbles that uses water hammering, a bubble generating nozzle, and an apparatus for generating micro-nano bubbles are provided to construct a system. The system is for generating micro-nano bubbles in a large amount using only pure water, which does not include any nucleating agents, and for performing not only a clean washing and sterilization but also the generation of uncontaminated micro-nano bubbles. The method defined in the present invention uses water hammering power produced by a mutual collision of jets of dissolved-gas-including solution squirted from two or more spouts. The bubble generating nozzle by the present invention has a configuration, including: a hollow cylinder having two or more small through-holes arrayed in the circumferential direction thereof and a micro-nano bubble discharge port provided on the both ends of the hollow cylinder, wherein the small through-holes are arranged so that all of their extension lines passing through respective center of the cross-section of each of the small through-holes which intersect each other in the inside of the hollow of the cylinder. The apparatus for generating bubble by the present invention has such bubble generating nozzle and has a configuration that enables generation of micro-nano bubbles in a large amount.

A humidifier includes a container defining a container cavity; a cover positioned over a container opening of the container cavity, the cover defining a body opening and a vent opening, the body opening and the vent opening in fluid communication with the container cavity; an attachment mechanism configured to attach the humidifier to a vent; and a wicking pad mounted in the container cavity between the vent opening and the body opening.

In accordance with embodiments of this disclosure, a gas humidifier system includes a reservoir of liquid with at least one selectively permeable tube at least partially submerged within the liquid. A gas stream may be fed into the selectively permeable tube that passes through the liquid reservoir. The selectively permeable tube may be substantially impermeable to the gas flowing therethrough but permeable to vapor (e.g., water vapor) entering the selectively permeable tube from the liquid. Thus, vapor from the liquid reservoir can enter the selectively permeable tube and humidify the gas flowing therethrough.

Disclosed is a carbonation device including: a storage tank storing a carbonation subject solution; a droplet spray unit spraying the carbonation subject solution from the storage tank as droplets; a carbonation reaction tank disposed with the droplet spray unit and filled with a carbonation gas under a predetermined pressure to provide a slurry by a carbonation reaction of the droplet-sprayed carbonation subject solution with the filled carbonation gas; a carbonation gas supply unit supplying the carbonation gas into the carbonation reaction tank to maintain the carbonation gas in the carbonation reaction tank under the predetermined pressure; and a slurry outlet unit ejecting the slurry from the carbonation reaction tank to maintain the slurry formed in the carbonation reaction tank within a predetermined level, and a method of carbonation using the same.

A method and system are used to enhance a marker material to include a plurality of air bubbles. The method of manufacturing a marker includes enhancing a marker material to include a plurality of air bubbles using at least a first EFD and a second EFD. The method may include cycling repeatedly through a transfer process between a first container and a second container. A system for enhancing a marker material includes a transfer apparatus configured to receive a marker material and a selected amount of air. The system comprises a first EFD coupled to a first end of the transfer apparatus and a second EFD coupled to a second end of the transfer apparatus.

A method of producing a canned hydrogen infused beverage having the steps of: providing a can; introducing a solid that includes metal into the can; filling the can with a carbonated liquid having water; generating molecular hydrogen from the reaction of the solid and the water; and sealing the can. A can formed through such a process is likewise disclosed. An alternative process is further disclosed that provides the mixing of Magnesium into a mixture prior to the filling on a larger scale and, for example, within the reservoir or bowl of the filler. Both carbonated and non-carbonated configurations are contemplated.
