    • 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 (28) of reactive biocide droplets is generated in a chamber (50) by atomization transducer (24) at ambient pressure from the biocide solution (10) and a flow (32) of carrier medium or air is provided in communication with the mist (28). The flow (32) 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.

    • An improved method and apparatus for producing an extremely fine micron and sub-micron size water mist (18) using an electronic ultrasonic device (8) that produces the mist at ambient-pressure and delivering the mist for application in suppressing fire. A piezoelectric transducer (10) 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 (16) 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. The water mist may be effectively utilized for mitigating blast and reducing over pressures. The fine water mist may also be utilized for humidification because of its fast vaporization and efficient cooling behavior. The apparatus may be modified in its physical design and direction of output, and the method may be modified by adjusting the throughput of mist, composition of mist, concentration of mist, and momentum of mist, whereby fire may be suppressed under many different scenarios.
    • 一种改进的使用电子超声装置(8)制造极细微米和亚微米尺寸的水雾(18)的方法和装置,其在环境压力下产生雾气并传送雾以用于抑制火灾。 压电换能器(10)被布置成产生具有亚微米级液滴的至少一部分的水雾。 水雾由高频压力波或预定或可变频率的超声波产生,包括可能超过2.5MHz的频率。 水雾被引导到火基地,被火焰的火焰自动夹带。 动量提供了将雾中引导的水雾最小化以增强火焰夹带雾的能力,并且载体介质的流动通常围绕产生雾的喷泉(16)切向地引导。 此外,控制雾的产量和浓度,以确保夹带的雾足以冷却和抑制火。 水雾可以有效地用于减轻爆炸和减少过压。 由于其快速蒸发和有效的冷却行为,细水雾也可用于加湿。 该装置可以在其物理设计和输出方向上进行修改,并且可以通过调节雾的生成量,雾的组成,雾的浓度和雾的动量来修改该方法,从而可以在许多不同的情况下抑制火灾。

    • 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 (10) or other process generates very small particles or droplets (28) from a reservoir (14) of liquid or material to be atomized. A helical flow (30) 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 (46). 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.
