Definitions

  • Fig. 2 is a schematic diagram showing one example of a dust collection unit 120.
  • Fig. 2 schematically shows a perspective diagram of the dust collection unit 120.
  • a shape of the dust collection unit 120 in the present example is cylindrical, but may be another shape such as a box shape.
  • the dust collection unit 120 of the present example has an opening 42 to which the exhaust gas is supplied, a gas flow path 44 through which the exhaust gas flows, and an opening 46 from which the exhaust gas is exhausted.
  • the exhaust gas which is supplied to the opening 42 contains the charged particles charged by the charging unit 110.
  • the gas flow path 44 has a partition wall 32 that surrounds a space through which gas flows.
  • the partition wall 32 may have a tubular shape. The charged particles are removed from the exhaust gas in the gas flow path 44.
  • the exhaust gas from which the charged particles have been removed is exhausted from the opening 46.
