Electrode rotary type DBD reactor

Abstract

The invention relates to an electrode rotary type DBD reactor. The electrode rotary type DBD reactor is characterized by comprising a framework, a vertical lifting platform, a high-voltage electrode module, a low-voltage electrode module, an insulating medium and a rotating motor. The high-voltage electrode plate is variable in number and convenient to install, and the low rotation speed of a low-voltage electrode plate is also used so that multi-period treatment can be realized under the condition that certain total treatment time is guaranteed, the treatment time and intermittent time of a single period are controllable, and the form is diversified; the occupied space of the whole reactor is small; an approximately closed reaction space can be conveniently obtained by installing organicglass on the framework, and discharging experiments of different environment gases such as air, pure nitrogen, pure oxygen or a nitrogen and oxygen mixed gas can be completed, and observation is convenient; advantages of a cutter row-roller type DBD reactor and advantages of a flat plate-flat plate linear motion type DBD reactor are integrated, bottlenecks of the two reactors are broken through, and the electrode rotary type DBD reactor has the advantages of facilitating gas gap adjustment, being controllable in speed and high in precision and is suitable for experimental research.

Description

technical field [0001] The invention relates to the field of DBD reactors, in particular to an electrode rotating DBD reactor. Background technique [0002] Dielectric barrier discharge (DBD) is one of the most common ways to generate non-equilibrium plasma. This discharge method is to insert an insulating medium between electrodes, which can avoid the transformation of discharge into arc and spark discharge. DBD under atmospheric air conditions has been widely used in industry, involving many fields such as sewage treatment, air purification, packaging printing and dyeing, and lithium batteries. Material surface modification is one of the important applications of DBD. It undergoes a series of physical and chemical reactions with the material surface through the plasma generated by DBD, changes the surface roughness of the material, introduces hydrophilic functional groups, and then improves the hydrophilicity of the material. , wettability, printing and dyeing properties....
