Abstract

The invention provides a sliding arc combustion supporting device producing atmospheric pressure non-equilibrium plasmas. The sliding arc combustion supporting device producing the atmospheric pressure non-equilibrium plasmas comprises a pressure gas pipeline, a center electrode pipe, a Laval spraying pipe, a cyclone and the like; a plurality of small holes are formed in the tail end of the center electrode pipe, fuel is sprayed out of the small holes to be atomized, and is fully mixed in the Laval spraying pipe with combustion-supporting gas rectified by the cyclone. The left end of the center electrode pipe is connected with a high voltage power source to serve as an anode; the Laval spraying pipe is grounded to serve as a cathode; the center electrode pipe and the wall face of the Laval spraying pipe perform discharging to generate the plasmas; arc columns of sliding arcs generate a catalysis reaction in a gas mixing area to perform combustion; and flames are sprayed out of the Laval spraying pipe to act on an external connection device. The sliding arc combustion supporting device producing the atmospheric pressure non-equilibrium plasmas is compact in structure, convenient to machine, high in combustion supporting efficiency and capable of being used for combustion supporting of a matched combustion device.

Description

technical field [0001] The invention relates to a combustion-supporting device, which belongs to the field of combustion chemical equipment. Background technique [0002] According to the particle temperature of plasma, plasma can be divided into high-temperature plasma and low-temperature plasma. Through control means and scientific methods, most of the plasmas that can be produced and widely used in industrial and agricultural production are low-temperature plasmas. According to the thermodynamic equilibrium characteristics of the arc region, low-temperature plasma can be divided into hot plasma and cold plasma. Cold plasma is a kind of non-thermal equilibrium plasma, the temperature of electrons is much higher than that of ions, and the temperature of ions is much higher than that of neutral particles. Judging from the existing literature, the methods of generating non-equilibrium plasma mainly include dielectric barrier discharge, high-voltage pulse corona discharge, hi...
