  • Publication number: 20190232094
    Abstract: A device, composition, and a process for a hybrid blend of inert gas and mist produced for fire protection by local or total flooding. The method mixes ultrafine water mist, preferably less than 20 microns diameter produced by atomization and an inert gas such as nitrogen. A homogeneous hybrid composition discharges from a swirling flow mixer-injector device. The hybrid composition extinguishes a fire source in reduced time by simultaneous and synergistic cooling with the mist and inerting with the inert gas. After extinction oxygen remains at a safe level of 12.5-15% (V). The high-velocity inert gas flow of 35-75 mph velocity in the mixing-injector column formed by an exit in the mixer-injector device entrains the low-velocity mist flowing out of atomizer. The device creates a swirling, high-speed, and expanding flow of the hybrid composition inside the fire protection volume at ambient pressure.

  • Patent number: 10238761
    Abstract: The present invention is an improved method for decontamination of a space and an integrated device that completes the decontamination cycle extremely fast while still being compact, lightweight, simple to operate and easy to move as a single unit. The method of the present invention delivers less biocide than is used in prior art methods at a very high rate of flux, allows the biocide to reside in the space being decontaminated to achieve a predetermined kill level, and then aerates the space. Because a nominal amount of biocide is used, there is less biocide to remove from the space than in prior art methods thereby reducing the time required for aeration and shortening the downtime for safe entry of the facility.

  • Patent number: 9533064
    Abstract: A mist generator is used to deliver a high throughput extremely fine mist comprising a biocide. Flows of evaporating hot gas mix turbulently and enhance forced heat and mass transfer between the very fine droplets and the hot gas to form a well-mixed premixed evaporator, resulting in high humidity vapor formation well inside a tube. The high relative humidity vapor with elevated temperature is then condensed as it exits the tube and disperses into the volume to be decontaminated as a condensed vapor cloud, but neither as a mist nor as a pure vapor depending on temperature and humidity of room environment. The condensed vapor cloud may evaporate or settle on the volume surfaces and contents, whereby both dry vapor and condensed vapor are applied into the volume for the killing process.

  • Patent number: 7834225
    Abstract: A method and device is presented for separating liquid mixtures using ultrasonic atomization and without subjecting the mixture to heat or thermal distillation. The process of ultrasonic separation does not involve liquid heating and saves up to 75% of the energy required as compared to thermal distillation. The method involves high throughput fixed bed atomizers with a specially designed carrier gas flow for aerosolization, extraction, and transport of mist. The mist richer in the desired component is then collected and condensed by electrostatic or other de-misting means. Repeated processes can achieve high separation efficiency. The efficiency of separation can be controlled by varying the ultrasonic frequency, power, and number of arrays, liquid surface tension and interfacial tension of mixtures.

  • Publication number: 20100218959
    Abstract: A method and device for suppression of fires related to heating appliances, vent hoods and work benches through deployment of very fine mist droplets, preferably less 100 micron diameter, into the firebase. A low momentum, high mist loading fine mist stream is introduced about the firebase. Mist is discharged to the firebase through diffusers or swirl channels so that the mist surrounding the firebase will be entrained into the firebase to secure and suppress the fire. After the fire is suppressed, the fine mist is further discharged to the hot oil surface for cooling.

  • Patent number: 7326382
    Abstract: A method of sterilizing a site or contained volume includes providing an aqueous biocide solution containing a biocide agent such as hydrogen peroxide. A mist of reactive biocide droplets is generated by atomization at ambient pressure from the biocide solution and a flow of carrier medium or air is provided in communication with the mist. The flow of carrier medium is controlled to generate a biocide mist comprising a concentration of stable mist droplets within the carrier medium. By controlling aersolization, extraction and delivery of the stable mist droplets, a sufficient portion of the stable mist droplets for a sterilizing treatment of a designated site do not coalesce prior to treatment interaction with the treatment site. The process of formation, stabilization and extraction are done in-situ so that droplets do not coalesce during transport.

  • Patent number: 7264773
    Abstract: The invention provides a method for generating a homogeneous aqueous mist solution containing a solvent such as water and a biocide agent such as chlorine dioxide, which would otherwise be unstable. The unstable biocide agent or chlorine dioxide is quickly dissolved or mixed with a mist of solvent causing the biocide agent to co-exist or co-mist therewith. The mist microencapsulates the biocide gas so that it does not decompose in the fumigation volume or space. The resulting homogenous mist solution provides a mist for delivering the biocide agent in a chemically stable form. Methods for mixing the separately generated mist and biocide gas include combining the mists in a Y-tube and then mixing the combination in a baffled mixing chamber, combining the mists in an area above their points of generation and then further mixing, and providing a series of mist generation units connected by a conduit for a carrier medium to pass to and connect the units and cause the mists to combine.

  • Publication number: 20070193874
    Abstract: An improved method and device is accomplished for ethanol production using an in-line extraction of ethanol by ultrasonic atomization, thereby removing the effect of the ethanol inhibition factor that adversely affects the rate and yield. The in-line removal of ethanol as it is formed increases the fermentation rate, improves the yield and uses 20-25% of the energy required as compared to thermal distillation processes currently used. The improved method makes sure that ultrasonic vibration does not deactivate enzymes to any significant level. The elimination of the effect of the ethanol inhibition factor allows for a continuous fermentation process as opposed to the costly, time-consuming repeated batch processes.

  • Publication number: 20060196681
    Abstract: An improved method and apparatus for producing an extremely fine micron and sub-micron size water mist using an electronic ultrasonic device that produces the mist at ambient-pressure and delivering the mist for application in suppressing fire. A piezoelectric transducer is arranged to produce a water mist having at least a portion of sub-micron size droplets. The water mist is produced by high frequency pressure waves or ultrasonic waves of predetermined or variable frequency, including frequencies which may exceed 2.5 MHz. The water mist is directed to a firebase to be self-entrained by the fire's flame. The momentum provided the water mist in directing the mist is minimized to enhance the ability of the fire to entrain the mist, and the flow of the carrier medium is usually directed tangentially about the water fountain creating the mist. Further, the throughput and concentration of the mist is controlled to ensure that the entrained mist will be sufficient to cool and suppress the fire.

  • Patent number: 6955063
    Abstract: A cooling method and apparatus including a mist-generating device is configured to generate a mist of droplets from water, dielectric liquids or any cooling liquids. The mist is produced having such volume, momentum, concentration and quality of scale so as to deter or avoid impingement or deposition of the mist droplets on a surface to be cooled or on surfaces within a heat dissipating system to be cooled. Effective cooling is provided by the high latent heat of vaporization of water or other suitable fluid, while surfaces normally subject to possible damage by wetting are protected from harmful contact from the fluid. Tangential flow technology and electronic ultrasonic atomizing devices may be used as one possible means to generate the required mist and control mist volume, momentum, concentration and quality. Other variables may be controlled to enhance the cooling of the mist, such as flow patterns and flow directions of the mist. Vaporized mist may be condensed and recovered.

  • Patent number: 6883724
    Abstract: The present invention provides a method and device for production, extraction and delivery of an aerosol mist with ultrafine droplets. A high frequency wave generating device or other process generates very small particles or droplets from a reservoir of liquid or material to be atomized. A helical flow of a carrier gas medium such as air is directed into a container and creates a high throughput aerosol of air and fine droplets. The aerosol is delivered through a suitable outlet such as by deflecting the aerosol upwards and providing a tube centrally situated with respect to the helical flow such that the aerosol will discharge through the tube in high quantity of throughput and high quality of stable aerosol of very fine mist droplets. The methods described utilize in-situ extraction of fine mist droplets using helical flow behavior as opposed to forced convection ejection of mist or inertial separation of droplets by separators.
