Abstract

The invention relates to a plasma air disinfection purifier for an automobile, which comprises a plasma reactor, a pulse power supply, a fan component, an air inlet, an air outlet and a casing and is characterized in that the plasma reactor is internally provided with multiple positive electrodes prepared by arranging nickel-chromium metal wires or metal bands in the same plane in an equidistant and parallel mode, and the positive electrodes are arranged on the middle position of each two adjacent negative electrodes; the two ends of each positive electrode are fixed on corresponding grooves or projections on an anti-microdischarge conductor rail; the two ends of the conductor rail are provided with insulation materials fixed on the corresponding positions of the casing; and the negative electrodes are made of an aluminum sheet after surface oxidation treatment, and the two surfaces of each negative electrode are laid with nanoscale TiO2. The plasma air disinfection purifier has high efficiency in disinfecting, absorbing inhalable particulates and degrading toxic and harmful gases, energy conservation, good reliability, long service life, simple structure and convenient installation, can be used for disinfecting and purifying dynamic air in an automobile especially a sedan, and also can be used for disinfecting and purifying air in subways, light rail carriages, offices, housing and the like.

Description

Technical field: [0001] The invention belongs to the technical field of air disinfection and purification, in particular to an automobile plasma air disinfection purifier. Background technique: [0002] It is reported that the Indoor Environmental Monitoring Center of the China Interior Decoration Association has conducted a survey on the air pollution in new cars. After random sampling of 200 cars, it was found that air pollution in cars is relatively common. If you refer to the national indoor air quality standard, 90% of the cars can't pass the test, and the formaldehyde of most vehicles exceeds the standard by more than five or six times. In another nationwide survey, only 52 of the 1,175 vehicles met the standards for all the inspection items, accounting for only 6.18% of the total number of vehicles tested. In-vehicle pollution has become an "invisible killer" that endangers people's health. . [0003] According to the analysis of experts from the Shanghai Indoor Env...
