Problems solved by technology

[0005] However, the current HEPA filter membrane and the common electrostatic precipitator technology are very poor at capturing particles with a dynamic diameter of less than 0.1um, and these particles are more harmful to the human body.

Abstract

The invention provides an electrostatic dust removal device. The device is characterized in that a positive and negative direct-current high-voltage ionization charge module, a positive and negative particle opposite movement and coagulation module and a particulate matter secondary electrification module are sequentially arranged in the air inlet direction. According to the electrostatic dust removal device, dust is collected after being subjected to positive and negative direct current high voltage, strong electric fields and secondary electrification high voltage, and high-working voltage is adopted, so that collection efficiency of particulate matters with the size of 0.1 um reaches over 99%; and the problem that the particulate matters with the size of 0.1 um cannot be collected in the existing electrostatic dust removal technology is solved, and therefore the purpose of removing the particulate matters in air in a space range can be achieved.

Description

technical field [0001] The patent of the present invention relates to the technical field of electrostatic dust removal, in particular, to an electrostatic dust removal device capable of eliminating PM2.5 dust particles. Background technique [0002] PM2.5-fine particulate matter, also known as particulate matter that can enter the lungs, is a general term for solid particles or liquid droplets in the air with an aerodynamic diameter less than or equal to 2.5 microns. These particles are so small that the human eye cannot see them, and they can float in the air for days. When the content of particulate pollutants with a diameter of less than 2.5 microns in each cubic meter of air increases by 10 micrograms, the long-term lung cancer mortality rate will increase by 8%. [0003] At present, the air purifiers produced in China are basically used to remove harmful substances such as formaldehyde and benzene, and there are few air purifiers that can remove PM2.5. Generally, the...
