Abstract

The invention provides a portable multifunctional air purification method and device. The method comprises the steps of (a) connecting a direct-current power supply to a direct-current transformer tooutput ultra-high voltage required for generating purified air plasma; (b) connecting the ultra-high voltage output by the direct-current transformer to a discharge electrode of a plasma generating device, and connecting the other electrode to the ground at the same time; (c) putting a catalytic module into the plasma generating device to efficiently catalyze air pollutants; and (d) starting the plasma generating device and a built-in fan to purify the air. The device provides the portable multifunctional air purification device for efficiently removing the pollutants such as PM25 and VOCs (volatile organic compounds).

Description

technical field [0001] The invention relates to the field of air purification, in particular to a portable multifunctional air purification method and device. Background technique [0002] With the development of industrial processes, environmental pollution is increasing day by day, and air pollution such as inhalable particulate matter, volatile organic compounds, ozone, and nitrogen oxides poses an increasingly serious threat to human health. Especially for indoor environments or closed spaces, particulate pollutants brought about by human actions such as cooking and smoking, and volatile organic compounds volatilized from paint and glue substances such as decoration and furniture are hidden in the air that people breathe all the time , although it is invisible and intangible, it has a huge impact on human health and becomes a potential hazard. In the field of air purification, especially the technology and equipment used in indoor or confined spaces, it has gradually at...
