Unpowered portable negative-ion air purification method

Abstract

The invention discloses an unpowered portable negative-ion air purification method and belongs to the fields of air purification and building environment science. A negative ion purification technology is taken as a principle, a battery is used for driving a negative ion generator to generate a large number of negative ions, the negative ions are discharged into the air and are combined with the air to form negative oxygen ions, and various physical and chemical processes are generated to remove pollutant particles, so that a clean and healthy local microenvironment is created without fan power. The power suitable for battery usage and human body carriage is selected by checking the power, equipment is integrated and the battery is arranged to realize convenience in carrying. The whole set of method comprises the negative ion generator, the battery and a brush for releasing the negative ions. The method has the characteristics of no pollution, no mechanical power, no noise, high efficiency, convenience in carrying, generation of negative oxygen ions beneficial for human body health and the like. Through actual detection, PM2.5 can be reduced from 200mu g/m<3> to 35mu g/m<3> in ten minutes. Meanwhile, the set of method can be combined with different equipment and used in different places, the structure is simple and the price is low.

Description

technical field [0001] The invention relates to an air purification method, in particular to a method for purifying air with unpowered portable negative ions Background technique [0002] my country's current PM2.5 pollution problem is serious, and PM2.5 particles in the indoor environment have seriously endangered people's health, and also caused sick building syndrome and reduced work efficiency. In this context, it is extremely urgent to design a practical PM2.5 air purification method. [0003] PM2.5 refers to pollutant particles in the air with an aerodynamic equivalent diameter of less than 2.5 μm. It can be suspended in the air for a long time, it is easy to adhere to toxic and harmful substances, and it is difficult to be filtered out by the human respiratory system, which is extremely harmful to the human body. [0004] At present, the PM2.5 air purifiers on the market are mainly filter-type, and a small amount of ionization-type, but these devices have significan...

AI Technical Summary

Problems solved by technology

[0004] At present, the PM2.5 air purifiers on the market are mainly filter type, and a small amount has ionization type, but these devices have significant shortcomings

The filter type requires high-power equipment, requires fans to provide mechanical power, and is noisy

At the same time, in order to ensure the filtration efficiency, the filter screen needs to be replaced frequently, and the cost is high

Some electrostatic precipitators are large-scale equipment, which are used in large spaces, and the air quality in the breathing area of ​​the human body cannot be guaranteed. At the same time, these equipment are also accompanied by the generation of ozone.
