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

Abstract

The invention discloses a control system of a DBD plasma reactor. The control system comprises a DBD plasma reactor, a sampling capacitor, a voltage division circuit for measuring the working voltageof the DBD plasma reactor, a frequency acquisition module, a voltage acquisition module, an adjustable power supply module and a controller, wherein the frequency acquisition module and the voltage acquisition module are used for respectively measuring the working frequency and the output voltage of the voltage division circuit, and the controller can adjust the output power of the adjustable power supply module according to the real-time operation parameters of the DBD plasma reactor. Obviously, the control system can adjust the power thereof according to the real-time operation state of theDBD plasma reactor, so that the problem that the gas treatment performance becomes poor when the system and environment conditions of the DBD plasma reactor are changed due to the fact that a power supply module always keeps constant power output in the prior art is solved, and the safety of the DBD plasma reactor in the using process is greatly improved.

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....
