Abstract:
1. A plasma sterilization and cleaning treatment device for an escalator, comprising: a plasma source having a planar discharge part arranged along a surface shape of an escalator hand rail and along a moving direction of the hand rail; an enclosure for housing the plasma source in encapsulated space; a pair of inlet parts located in the enclosure so as to communicate the encapsulated space to the outside atmosphere along the moving direction of the hand rail; filter plates arranged at the pair of the inlet parts, having a shape along a cross sectional surface shape of the hand rail, and having a microgap between the filter plate and the surface of the hand rail; and a power source for the plasma source, wherein the plasma source generates plasma close to the surface of the hand rail in an atmospheric pressure atmosphere; and wherein the filter plate has a filter for removing radicals generated in the space by the plasma and organic matters on the hand rail removed by the plasma.
