Greenhouse gas conversion device and method utilizing magnetic field to strengthen blade gliding arc

Abstract

The invention discloses a greenhouse gas conversion device and method utilizing a magnetic field to strengthen a blade gliding arc. The device comprises a blade gliding arc stabilization system and areactor. The blade gliding arc stabilization system comprises a first DC power supply, a second DC power supply, an inductance coil, a diode and an electromagnetic relay switch. The voltage of the second DC power supply is greater than that minimum breakdown voltage between two electrodes of the reactor. The voltage of the first DC power supply is 1/8-1/2 of the minimum breakdown voltage between the two electrodes of the reactor. The second DC power supply provides breakdown voltage, and the first DC power supply maintains power feeding. The reactor consists of an encloser, two electrodes, twoflat magnets and a nozzle. The encloser is a straight quadrangular prism structure with a rectangular cross section, and the two flat magnets are arranged outside the encloser parallel to each other.The invention improves the traditional blade reactor, utilizes the dual driving of the magnetic field and the airflow field, significantly improves the treatment capacity on greenhouse gas, and greatly prolongs the reactor lifetime.

Description

technical field [0001] The invention relates to a greenhouse gas conversion device, in particular to a greenhouse gas conversion device and method using a magnetic field to strengthen the sliding arc of a blade. Background technique [0002] Gliding arc discharge plasma (Gliding arc discharge, GAD) was first proposed by French H. Lesueur and A. Czernichowski et al. in 1988. It is a kind of non-equilibrium plasma that can swing periodically under atmospheric pressure. The traditional sliding arc reactor is mainly composed of two diverging electrodes. An air inlet nozzle is arranged at the top of the throat of the two electrodes. Both sides of the electrode are connected with high voltage, which breaks down from the throat of the electrode. Driven by the airflow, the arc Moving along the edge of the two stages, the arc elongates until it goes out, and then breaks down again at the throat to form a new arc, repeating the cycle.

Problems solved by technology

However, the arc drive method of the traditional blade sliding arc is only driven by the air flow, and there is a large speed difference between the arc and the air flow, and the arc is easily broken due to the heat loss caused by the excessive speed difference, so the entire plasma area is limited to a very small area. In a small area, and the traditional reactor cover is cylindrical, most of the reaction gas from the nozzle does not pass through the plasma area, which limits its ability to treat greenhouse gases. At the same time, the sliding arc of the blade will cause cathode spotting , long time discharge will damage the reactor
