nanopowder separating device using an electrostatic trap in a metal nanopowder manufacturing equipment based on aerosol process

摘要

The present invention is a vapor phase process that allows the separation of nanopowders in the size range of several tens of nanometers or less of the nanopowders through the difference in the electrostatic force according to the powder size before the final extraction step of the nanopowder in the metal nanopowder manufacturing equipment of the gas phase process. The present invention relates to a nanopowder classification apparatus using an electrostatic trap in a metal nanopowder manufacturing facility. Nano powder classification apparatus (A) using the electrostatic trap in the gas phase process metal nano powder manufacturing equipment according to the present invention, In the nanopowder transport line 20 which is continued from the electroexplosion chamber 10, the buffer trap 30 using the gravity sedimentation method and the cyclone 40 using the inertial collision method are sequentially provided, and the nanopowder transport line 20 is provided. After the cyclone 40 of the circular duct 51 connected to the nano-powder transfer line 20, the electrode rod 52 located in the center of the circular duct 51, and the Teflon material surrounding the electrode 52 The protective tube 53 and the electrostatic trap 50 made of a Teflon insulator 54 mounted on the wire 55 connected to the electrode 52 is provided.
