Control system, method, device and medium of dbd plasma reactor

Abstract

The present application discloses a control system for a DBD plasma reactor, comprising: a DBD plasma reactor, a sampling capacitor, a voltage divider circuit for measuring the working voltage of the DBD plasma reactor, and a voltage divider circuit for measuring the voltage divider circuit respectively. A frequency acquisition module and a voltage acquisition module for operating frequency and output voltage, an adjustable power supply module and a controller, wherein the controller can adjust the output power of the adjustable power supply module according to the real-time operating parameters of the DBD plasma reactor. Obviously, the control system can adjust its own power according to the real-time operating state of the DBD plasma reactor, thereby avoiding the constant power output of the power supply module in the prior art, and the DBD plasma reactor changing in system and environmental conditions At the same time, the problem of poor performance of the processing gas occurs, which greatly improves the safety of the DBD plasma reactor during use.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a control system, method, device and medium of a DBD plasma reactor. Background technique [0002] Because DBD (Dielectric Barrier Discharge, dielectric barrier discharge) plasma reactor does not need vacuum equipment, it can obtain the active particles required for chemical reactions at room temperature or near room temperature, so DBD plasma reactor is used in The field of air purification technology. [0003] However, in the prior art, the DBD plasma reactor operates according to the preset power supply, and the discharge power of the DBD plasma reactor cannot be adjusted according to the real-time operating parameters of the DBD plasma reactor, which will not only make the DBD plasma Moreover, it is easy to cause the DBD plasma reactor to produce harmful gases such as ozone or nitrogen oxides, which leads to great safety hazards in the use of the DBD plasma reactor....
