Abstract

The invention discloses a PM2.5 particle removing method. A sweeper scans the frequency of PM2.5 particles in the air and gives a power signal through a detection circuit, the frequency of a power drive frequency-sweeping oscillation circuit is consistent to the PM2.5 particle frequency to form resonance, and small PM2.5 particles are changed into large particles and settle under the gravity effect. The sweeper is connected to a power supply through the detection circuit, the power supply is connected to the frequency-sweeping oscillation circuit, and the frequency-sweeping oscillation circuit is connected to the sweeper. According to the PM2.5 particle removing method, air purification is achieved by scanning the frequency of the PM2.5 particles in the air and utilizing the frequency consistency between an oscillating electric field and the PM2.5 particles to achieve resonance so as to change the PM2.5 particles into the large particles, enable the particles to settle and achieve air purification. The PM2.5 particle removing method is low in energy consumption and good in effect compared with electrostatic dust removal.

Description

technical field [0001] The invention relates to the field of air purification, in particular to a method for removing PM2.5. Background technique [0002] PM2.5 refers to particulate matter with a diameter less than or equal to 2.5 microns in the atmosphere, also known as particulate matter that can enter the lungs (no standard Chinese name for now). Although PM2.5 is only a small component of the earth's atmospheric composition, it has an important impact on air quality and visibility. PM2.5 has a small particle size, is rich in a large amount of toxic and harmful substances, and has a long residence time in the atmosphere and a long transportation distance, so it has a greater impact on human health and the quality of the atmospheric environment. [0003] Electrostatic dust removal is a kind of gas dust removal method. The dust-containing gas is electrically separated when it passes through the high-voltage electrostatic field, and the dust particles and negative ions ar...
