Problems solved by technology

[0013] What's more, even the plasma reactor is simply abandoned, and it is changed to an electronic electrostatic adsorption type with needle-shaped electrodes for electrostatic discharge. It can only absorb dust, and its ability to decompose toxic organic matter is not as good as the plasma reactor. It would rather sacrifice disinfection Purification effect, in exchange for the reliability and working life of the decontamination purifier

Abstract

The invention relates to a non-thermal plasma reactor, belonging to the technical field of air disinfection and purification. The reactor comprises positive electrodes, negative electrodes and a shell, wherein the positive electrodes are arranged in the middle of two adjacent negative electrodes; and an air inlet is arranged at the front end of the shell and an air outlet is arranged at the rear end of the shell. The reactor is characterized in that the positive electrodes are made into a component in such a way that a plurality of metal wires or metal straps are arranged in the same plane and are arranged in parallel in equal distance; the negative electrodes are made of aluminium sheets or stainless steel sheets; the two ends of the positive electrodes are fixed on conductor rails preventing microdischarge; the two ends of the conductor rails are fixed with positive electrode metal supports; and each positive electrode metal stent is fixed with the shell by insulating connecting columns and is electrically connected. The reactor effectively prevents microdischarge of positive electrodes, prolongs the operation lives of the metal wires or metal straps, reinforces the concentration of the plasmas generated by the reactor and saves energy. The reactor is widely applied to non-thermal plasma air disinfection purifiers.

Description

Technical field: [0001] The invention belongs to the technical field of air disinfection and purification, and in particular relates to a non-thermal plasma reactor. Background technique: [0002] The non-thermal plasma reactor used for the existing air disinfection purifier is mainly composed of a positive electrode, a negative electrode and a shell. The structure of the positive electrode is wire, sawtooth or pointed needle. [0003] Plasma is composed of a large number of positive and negative charged particles and neutral particles, and exhibits a collective electric field effect, and the overall charge is quasi-neutral gas cloud. Plasma seriously breaks down and destroys the bacterial cell membrane; moreover, it can open gas molecular bonds to generate single-atom molecules, negative oxygen ions, OH ions and free oxygen atoms, H 2 o 2 and other free radicals, with strong activation and oxidation capabilities. It has strong lethality to bacteria and viruses. It can ...
