Abstract

The invention discloses an air purification device. The air purification device comprises a shell, a high-voltage electrostatic dust removal unit and an air blower; the dust removal unit comprises an ionization unit and a dust collecting unit located at a downstream position of the ionization unit; a first gap and a first working voltage are set between the positive electrode and the negative electrode of the ionization unit, wherein the first working voltage is set to be capable of ionizing particles in air passing through the ionization unit, and the first gap is set to be not less than the insulation distance of the air and enable the ionized particles to pass through the ionization unit; and a second gap smaller than the first gap and a second working voltage smaller than the first working voltage are set between the positive electrode and the negative electrode of the dust collecting unit, wherein the second gap and the second working voltage are set to enable the ionized particles to be adsorbed on the electrodes of the dust collecting unit so as to achieve the dust removal function. According to the air purification device, the purification efficiency can be ensured, and the generation amount of ozone can be minimized. The invention further discloses an air purification method.

Description

technical field

[0001] The invention relates to an air purification device and an air purification method, in particular to an air purification device and a method for removing particles in the air by using high-voltage static electricity. Background technique

[0002] As people's requirements for indoor air quality are increasing day by day, the use of air purification devices is also becoming more and more common. People generally hope to use air purification devices to remove particulate matter in the indoor air, that is, dust removal. According to the principle of dust removal, traditional air purification devices can be divided into two categories: physical filtration and electrostatic dust removal. Traditional physical filtration and purification devices use high-density filters to filter particulate matter in the air. The characteristic of physical filtration is that the smaller the particle size to be filtered, the smaller the mesh size of the filter. Too small me...
