Atmospheric pressure magnetic field enhanced low temperature plasma brush generator

Abstract

The invention provides an atmospheric pressure magnetic field enhanced low-temperature plasma brush generator, comprising a main chamber with an air inlet port and an air outlet port, a pair of main discharge electrodes and a pair of dielectric barrier discharge plate electrodes, the main chamber is made of insulating material Made; the gas outlet port is in the shape of a slit, and the part of the main chamber close to the gas outlet port forms a slit cavity, and the ratio of the width to the thickness of the gas outlet port is 5 to 100; the discharge end of the main discharge electrode is located at the The slit cavity; the flat electrode is located between the air inlet port and the main discharge electrode, and is used to pre-ionize the working gas; outside the slit cavity, a permanent magnet is arranged to make the electrons and ions generated by the discharge changes happened. The invention skillfully utilizes the principle of electromagnetic induction, and simply and effectively realizes the purpose of reducing work energy consumption and operation cost.

Description

technical field [0001] The invention relates to a low-temperature plasma brush generating device. Background technique [0002] The dielectric barrier discharge enhanced low-temperature plasma brush generator disclosed in Chinese patent ZL201210006023.4 "Dielectric Barrier Discharge Enhanced Low-Temperature Plasma Brush Generator" consists of a main chamber, a pair of main discharge electrodes, and a pair of dielectric Barrier discharge (DBD) plate electrodes, a current limiting resistor, a mass flow meter and two power supply devices. The main body chamber includes two ports, one port is an air inlet port, and the other port is an air outlet port, and the part of the main body chamber close to the air outlet port naturally forms a slit cavity. Two electrodes for the main discharge are arranged at the slit cavity, and the discharge end faces facing each other are flat or needle-shaped. A current-limiting resistor is also connected in series on the loop of the main discharg...

Problems solved by technology

[0005] However, further considering energy saving, emission reduction and maintenance cost, this device is still not ideal

Since the current limiting resistor is set in the discharge circuit, there is still more energy consumed on the resistor and wasted; secondly, in order to generate a larger volume of plasma jet, a higher gas flow rate is required, thus increasing the operating cost
