The disclosure relates to a flexible active species generator comprising: a first electrode of a conductive metal thin film; a second electrode of a ground electrode; a flexible dielectric layer of an insulator formed between the first electrode and the second electrode; and a plasma resistant functional layer formed between the dielectric layer and the second electrode, wherein the first electrode and the second electrode are electrically connected to an external power supply to generate an atmospheric pressure plasma to generate active species. The flexible active species generator has a plasma resistant function to prevent deformation and decomposition of an insulator caused by the plasma as well as an active species generating function from atmospheric pressure plasma, and has durability and safety, which is thus applicable to articles, foods, garments and human body in various forms.

Flexible active species generator and use thereof

The present invention relates to a method for exhausting high concentrations of toxic gases generated during chemical stripping for high-temperature parts of a gas turbine, the method including the steps of: allowing a pair of openable/closable doors mounted on top of a tank whose top is open to accommodate a chemical substance therein to be closed during the chemical stripping so as to close top of the tank; collecting the toxic gases generated from the interior of the tank through hoods located at the inside of the tank; and exhausting the toxic gases to the outside through exhaust pipes mounted on the hoods or collecting the toxic gases to a separate storage tank.
