Non-thermal plasma air-purifying and disinfecting reactor

Abstract

The invention relates to a non-thermal plasma air-purifying reactor which comprises a housing, a positive electrode, a negative electrode, an external draught fan and a power supply, wherein the positive electrode is arranged between two adjacent negative electrode plates, is in insulating connection with the two adjacent negative electrode plates, and is equipped with an air inlet and an air outlet at the same time, wherein a distance between the positive and the negative electrodes is not smaller than twice a power-generation distance; the positive electrode is fixed on an insulation piece by a positive electrode connection piece; the insulation piece comprises insulation rings; the positive electrode comprises n metal belt groups which are fixed on the positive electrode connection piece, each metal belt group is arranged between two adjacent negative electrode plates, and the metal belt groups are formed by arranging oxidization-resistant metal wires or metal belts at equal distance in the same plane; (n+1) rows of negative electrode plates which are arranged in parallel with the ventilating direction of the reactor are fixed on the reactor housing by negative electrode connecting plates to form the negative electrode; the negative electrode plates are detachably arranged on the negative electrode connecting plates; through holes in which the insulation piece is embedded are formed on the negative electrode connecting plates; and the insulation rings are embedded in the through holes. The non-thermal plasma air-purifying reactor disclosed by the invention greatly improves the purifying effect.

Description

technical field [0001] The invention belongs to the technical field of air purification and disinfection, and in particular relates to a non-thermal plasma air purification reactor. Background technique [0002] The non-thermal plasma reactor used in the existing air purification sterilizer is mainly composed of a positive electrode, a negative electrode and a reactor shell. Some of the positive electrodes are made of metal filaments or thin metal strips, and some are made of stainless steel skins into jagged or pointed needles. [0003] The superiority of non-thermal plasma air purification and disinfection has also been recognized by more and more people inside and outside the industry, but it is still not widely used in the market. Research has confirmed that the reason is that the current non-thermal plasma reactor design is unreasonable and unscientific : Although the positive discharge electrode of the non-thermal plasma reactor selects fine metal wire to produce plas...

Problems solved by technology

The use of ozone and ultraviolet light below 270 nanometers can only kill bacteria and viruses, but cannot decompose and remove organic compounds such as formaldehyde, and humans and machines cannot coexist

single use TiO 2 Photocatalysis to purify air has little effect
