Abstract:
The invention suggests a spray element 20, in particular for die spraying devices 10, comprising supply means 42 for liquid working medium and, optionally, supply means 50 for control air, an atomizing device 78/80b connected with supply means 42 for working medium and a switch valve 62 controlable in dependence of pressure, said switch valve 62 having a flexibly biassed valve body 68 for alternatively establishing or interrupting the connection between the supply means 42 for working medium and the atomizing device 78/80b. In spray element 20, the valve body 68 is designed as having inherent flexible bias.
Abstract:
The invention relates to a new atomizing device with improved droplet formation. Smaller droplets are formed with increased micronized volume throughput, wherein high volumes of air are fed to a liquid sprayed from a liquid nozzle (2). High volume ratios result in mean free path between droplets being conveyed so as to minimize collisions and to prevent aggregation of the droplet.
Abstract:
El objeto de la presente invención es un dispositivo y procedimiento de atomización o nebulización de un líquido objeto de análisis espectrométrico mediante el uso de un gas impulsor que es ntroducido a presión en dicho dispostivo. Ambos fluidos son expulsados al exterior tras su mezcla, prodciéndose la salida del líquido en forma de aerosol o suspensión de gotas arrastrada por la corriente de gas. El objetivo que se persique es la consecución de un nebulizador, destinado a su uso en análisis espectroscópico inorgánico (atómico y de masas), que asegure las siguienes propiedades: a) escaso caudal líquido y gaseoso; b) robustez de materiales y de manejo; c) facilidad de uso; d) alto control del tamaño de gota; e) generación de aerosoles finos y mono-dispersos.
Abstract:
An atomizer(5) for atomizing a liquid has a gas chamber (15) adapted to be connected to a supply of gas and a liquid chamber (30) adapted to be connected to a source of liquid. A mixing tube (38) extends from the gas chamber (15) in a downstream direction, and atomizing gas flows through the tube (38) at subsonic speed. A liquid conduit (32) fluidly connects the liquid chamber (30) with the mixing tube (38) so that liquid from the conduit (32) can be entrained in the gas flow for discharging a mixture of gas and partially atomized liquid from the tube (38). The mixture then flows through an exit gap (65) to the exterior of the housing (10). The exit gap (65) has several successive shear steps (45) which contact the mixture as it flows through the gap (65) to thereby substantially fully atomize the liquid as it is being discharged from the atomizer (5). The atomizer (5) permits variations in the liquid flow rate and therewith variations in the rate at which atomized liquid is discharged from the atomizer (5) by modulating the rate at which the liquid is entrained in the gas streams while maintaining the gas stream flow rate and pressure substantially constant.
Abstract:
A liquid spray device, comprising a container (1), a spray injection nozzle (2) for injecting oil spray into the container (1), a spray feeding path (5) for feeding oil spray in the container (1) to the outside of the container (1), oil (11) stored in the container (1), a gas exhaust port provided in the oil (11), and a submerged nozzle (4) for producing oil spray from the oil (11) by discharging gas into the oil (11), whereby the flow velocity of the oil spray in the spray feeding path can be increased and the amount of oil spray can be increased because an internal pressure of the container can be increased and an oil spray different from the oil spray from the spray injection nozzle can be produced.
