A fluid dispersion system and method used for spraying large areas with near-monodispersed, aerosolized fluid droplets. More specifically, the system creates and distributes a cloud of near-monodispersed droplets of fluid by pumping pressurized air and fluid through fluid dispersion machinery and into, and out of, a fluid dispersion nozzle. The fluid dispersion machinery is a combustion engine-driven air compressor system that includes an engine, radiator, fuel tank, fluid tank, fluid piping system, fluid pump, air compressor, air compression intake, one or more fluid dispersal nozzles, air ducting, clutch, and control system. The method of fluid dispersion is implemented at night during a nighttime air inversion when there is a temperature difference between the temperature of air at the top of an object and the temperature of air near the ground surface.

A nebulizer for producing an inhalable mist of droplets, comprising at least an aerosol generator, a housing having a liquid reservoir and control electronics, the aerosol generator consisting at least of a membrane, a piezo element and a substrate plate, and the control electronics comprising at least an RF generator, a controller, memory and switching elements, and an inductor. The aerosol generator forms a resonant circuit together with the inductor and the control electronics are configured to at least partly excite the aerosol generator to vibrate. The aerosol generator is configured such that aerosol droplets are producible by vibrations and the RF generator is configured to vary the amount of aerosol produced.

An acoustic force assisted painting system includes a housing, a nozzle, and at least one first transducer. The conduit is configured to receive paint from an external source. The nozzle is disposed in the housing. The nozzle has an inlet that is fluidly connected to the conduit and is configured to receive paint from the conduit. The nozzle has an outlet configured to dispense the paint. The at least one first transducer is disposed in the housing at a location downstream of the nozzle outlet in a flow direction of the paint.

The present invention discloses a water mist nano gasification conversion device, including a main body (1), an electronic high-voltage generator (5), a water inlet (3), a water supply tank (4), an electronic water mist spraying device (6) arranged in the water supply tank (4), and an atomization tube (2) arranged above the water supply tank (4).

A processing liquid nozzle according to an aspect of the present invention comprises an ultrasonic application part (60), a first supply flow path (71), a discharge flow path (72), and a second supply flow path (73). The ultrasonic application part (60) has a vibrator (61) for generating ultrasonic waves, and a vibrating body (62) joined to the vibrator (61). The first supply flow path (71) supplies a first liquid (L1) to a position contacting the vibrating body (62) of the ultrasonic application part (60). The discharge flow path (72) supplies the first liquid (L1), to which ultrasonic waves have been applied by the ultrasonic application part (60), to a discharge port (74). The second supply flow path (73) is connected to the discharge flow path (72) on the downstream side from the ultrasonic application part (60), and supplies a second liquid (L2) to the discharge flow path (72).

A decontamination system not requiring large-scale equipment such as large-diameter ducts and anti-condensation heaters and for that reason capable of efficiently using a decontamination liquid. Long pipes can be installed for each of a plurality of rooms to be decontaminated, a decontamination liquid is not present in supply pipes as a residual dead liquid, and a proper amount of decontamination liquid can essentially be supplied for each room to cause no failure of an ultrasonic vibrator.

The decontamination system employs a decontamination mist and includes a compressed air generating means and a decontamination liquid supplying means, and each room to be decontaminated is provided with a primary mist generating means and a secondary mist generating means. The conveyance distance of a primary mist supply pipe communicating the primary mist generating means and the secondary mist generating means is longer than the conveyance distance of a decontamination liquid supply pipe communicating the decontamination liquid supplying means and the primary mist generating means.

A dry burning detection method, applied to a vaporizer, includes: obtaining vaporization parameters of a vaporization piece in real time, and calculating a variance between the vaporization parameters and a sample mean, the sample mean being a value representing a vaporization parameter level of a stable vaporization stage of the vaporizer; and determining that the vaporization piece is dry-burned if the variance is greater than a preset variance value corresponding to the vaporization parameter, the preset variance value being used for distinguishing a vaporization parameter fluctuation caused by vaporization dry burning and a vaporization parameter fluctuation caused by non-vaporization dry burning.
