Adjustable plasma generating device

The utility model relates to an adjustable plasma generating device, which comprises a reaction tube; the plurality of electrode groups are positioned in the reaction tube; the electrode group comprises an anode electrode column and a cathode electrode column which are oppositely arranged and have an adjustable distance, so that current is formed between the anode electrode column and the cathode electrode column after the electrode group is electrified; and the air blower is positioned at the upstream of the plurality of electrode groups and is used for generating airflow flowing to the space between the anode electrode column and the cathode electrode column so as to generate a plurality of sliding arcs. According to the utility model, plasma particles are continuously generated in a closed space, the concentration gradient is continuously increased, the stability is better, and a green, environment-friendly, efficient and residue-free sterilization mode can be provided. 本实用新型涉及一种可调等离子发生装置，包括：反应管；多组电极组，位于所述
