The invention discloses a dust-removing
air purifier with double functions of anion
sedimentation and high-
voltage electrostatic adsorption. The dust-removing
air purifier comprises a casing as well as an anion emission needle plate, a stacked high-
voltage electrostatic
cell, a positive pole filtering body and a fan which are sequentially arranged, wherein anion emission needles which
discharge towards the positive pole filtering body and form
potential difference with the positive pole filtering body are arranged on the anion emission needle plate, the stacked high-
voltage electrostatic
cell comprises negative plates and positive plates, an
air channel is formed between each negative plate and the adjacent positive plate, each negative plate comprises two insulators with
high resistance and
high voltage resistance and a conductor which is located between the two insulators and has
low resistance, and the positive plates have electrical
conductivity and can lead out charges carried by electronegative particles directly contacted with the positive plates in the air channels. According to the dust-removing
air purifier, the wind resistance is low, the use
noise is small, frequent cleaning is not required, single
air purification efficiency is high,
bacteria and viruses in air can be killed, the problems about wall blackening and influence on
human health are solved, and secondary
pollution caused by starting up is avoided.
