FINE-PARTICLE-CAPTURING DEVICE AND POWDER-PROCESSING SYSTEM INCLUDING THE SAME

원문 (중국어)

A fine-particle-capturing device includes: a support unit made of metal and disposed near a fine-particle source capable of generating fine particles in a vaporized state; an exhaust unit having an exhaust opening that opens in the support unit made of metal, the exhaust unit causing air containing the fine particles generated by the fine-particle source to flow in a discharging direction from the exhaust opening; and a capturing component provided to cover the exhaust opening of the exhaust unit, the capturing component capturing the fine particles. The capturing component includes: a capturing unit including a plate-shaped member made of metal in which micropores are regularly arranged, the micropores extending through the plate-shaped member in a thickness direction and having a polygonal cross-section; and a holding unit made of metal having a cavity at least in a region between the capturing unit and the exhaust opening, the holding unit holding the capturing unit at a location separated from the exhaust opening. The holding unit is supported by the support unit at a downstream location in a direction in which the air passes through the capturing unit.
