A low-temperature plasma reactor having an adaptive rotating electrode includes a frame. A reaction tube is arranged inside the frame. A fixing cover is arranged on each of two sides of the frame. The fixing cover defines a through hole communicating with an inside of the reaction tube. The through hole in one of the two sides serves as an air inlet hole, and the through hole in the other one of the two sides serves as an air outlet hole. A rotatable inner electrode is arranged inside the reaction tube, a plurality of groups of discharging needles are arranged on a surface of the inner electrode. A rotating fan is arranged on the inner electrode and is disposed on a side of the air inlet hole. The gas flow drives the inner electrode and the discharging needles to rotate, and a motor drive is not required.

A resource recovery system for reducing carbon dioxide emissions is revealed. Salt is delivered to a first plasma decomposition unit and decomposed into sodium and chlorine. The sodium is sent to a hydrolysis unit and mixed with water to get pure hydrogen and sodium hydroxide which are respectively sent to a power generation unit for power generation and a carbon dioxide absorption unit to react with carbon dioxide from air and produce a mixture of sodium carbonate and sodium bicarbonate. Then the mixture is delivered to an electric heating unit and broken into carbon dioxide and sodium hydroxide. The carbon dioxide is sent to a second plasma decomposition unit and decomposed into carbon and oxygen gas which is delivered to the power generation unit for generating power. Thereby catalysts, power required, and coproducts are obtained during operation of the system. Therefore, the system offers energy, environmental, and economic benefits.

The air treatment apparatus includes a ducting section having an inactivation zone created by either a plasma-generating flexible electrode alone, a UV light source alone, or a combination of a plasma-generating flexible electrode and a UV light source disposed within the interior of the ducting section, wherein the airflow and airborne pollutants are urged into the inactivation zone ensuring multiple exposures of airborne pollutant material into the inactivation zone resulting in purified air exiting from the apparatus.

Systems, methods, and apparatus are contemplated in which a tube cell that produces a dielectric barrier discharge (DBD) is individually configured to minimize the mixing of unwanted byproducts of the generated plasma with an exhaust air stream. The tube cell generates a DBD within a tube cell, such that oxidants or radicals are generated in an environment substantially separated from the exhaust stream. The generated oxidants are directed to intersect with the exhaust stream to minimize the generation of unwanted byproducts. The tube cells are further shaped and arranged in tube cell arrays to alter the flow dynamics of the exhaust stream and the oxidant or radical streams, including mixing of the streams.
