Abstract

The invention discloses a gliding arc discharge plasma generation system, belongs to the technical field of plasma energy conversion, and can solve the problems of low plasma power supply efficiency and poor H2 and CO selectivity in the existing system. The system comprises a discharge device which comprises an insulating base, a cover body arranged on the insulating base, and two blade-shaped electrodes arranged in the cover body; the two blade-shaped electrodes are both provided with arc-shaped edges, and the arc-shaped edges of the two blade-shaped electrodes are oppositely arranged; the gas distribution device is used for conveying mixed gas of air and fuel gas to an area between the two blade-shaped electrodes by penetrating through the insulating base; the constant-current alternating-current power supply is used for supplying power to the two blade-shaped electrodes, so that sliding arc plasmas are generated in the cover body; the discharge frequency of the constant-current alternating-current power supply is adjustable; and the electrical characteristic detection device is used for detecting the discharge current and the discharge voltage of the discharge device. The method is used for plasma hydrogen production.

Description

technical field [0001] The invention relates to a sliding arc discharge plasma generation system, which belongs to the technical field of plasma energy conversion. Background technique [0002] Compared with catalytic reforming hydrogen production technology, plasma hydrogen production technology has the characteristics of simple reaction device structure, rapid start and stop, low investment and operating costs, and high energy density, and has received a lot of attention in recent years. Sliding arc discharge plasma is a kind of non-thermal equilibrium plasma, which has the characteristics of hot plasma and cold plasma. Compared with corona, glow and dielectric barrier discharge plasmas, gliding arc discharge plasmas have higher electron temperature and electron density, and lower gas temperature (approximately equal to the rotational temperature). Therefore, gliding arc discharge plasma is widely used in the field of plasma hydrogen production technology. Methane and ot...
