    摘要: An apparatus and method for manufacturing ultra-fine particles using an electrospray device is disclosed. One or more capillary provided at its tip with a nozzle is positioned within a guide duct and precursors such as metal organic materials and metal halogen compounds, or nonvolatile substances or volatile substances are supplied to the capillary. Voltages are applied to the capillary and the guide duct, respectively, so that a voltage difference is generated therebetween and the highly charged liquid droplets from the capillary are sprayed. The sprayed liquid droplets are carried along the guide duct together with carrier gas injected into the guide duct. When heat energy is applied to the liquid droplets, chemical reactions of the liquid droplets occur. A collecting plate positioned in front of the guide duct collects ultra-fine particles formed by the chemical reactions.

    摘要: A device for collecting dust using highly charged hyperfine liquid droplets formed through an electro-hydrodynamic atomization process is disclosed. In the dust collecting device of this invention, a high voltage is applied to capillaries, set within a dust guide duct and having nozzles at their tips. An electric field is thus formed between the capillaries and the duct, and allows the nozzles to spray highly charged hyperfine liquid droplets. Such liquid droplets absorb dust laden in air, flowing in the duct by suction force of a fan. An electrostatic dust collector is detachably coupled to the duct while being insulated from the duct, and forms an electric field having polarity opposite to that of the highly charged liquid droplets, thus electrostatically collecting and removing the dust absorbed by the highly charged liquid droplets. The dust collecting device of this invention easily and effectively removes fine dust having a size smaller than 0.1 cm. This device is also preferably operable at low cost while achieving a desired dust collection effect, and is collaterally advantageous in that it humidifies discharged air, when water is used as the liquid for atomization of the hyperfine liquid droplets.
