The chamber body further includes a gas inflation inlet, in a wall of the chamber body, configured to introduce a swirl gas flow into the chamber body. The chamber body further includes a gas exhaust opening configured to discharge gas so as to, together with the gas inflation inlet, generate a tornado type gas flow in the chamber body, which moves spirally from the first end to the second end of the chamber body.
