Electrostatic air purification device and method

Abstract

The invention provides an electrostatic air purifying device, which is used for purifying air entering through an air inlet (1) and discharging purified air out through an air outlet (6). The device comprises an ionization device (2), a water-washing device (3) and a negative plate (4), wherein the ionization device (2) is arranged at the air inlet (1) and used for converting dust in air into charged particles; the water-washing device (3) is arranged at the air inlet (1) and used for washing air passing through the ionization device (2) with water and enables part of charged particles combined with water to flow away along with water; the negative plate (4) is used for adsorbing the charged particles in the air passing through the water-washing device (3). The electrostatic air purifying device provided by the invention is provided with the water-washing device and the negative plate which are used for cleaning air twice through water washing and electrostatic adsorption, so that dust in the air can be effectively removed, the air purification efficiency is improved, and the possibility of harming a human body by ozone is reduced since ozone is dissolved in water and ozone generated during the ionization process can be absorbed through water washing.

Description

technical field [0001] The invention relates to electrostatic dust removal technology, in particular to a household electrostatic air purification device and an electrostatic air purification method. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for quality of life, so they pay more and more attention to air quality. For this reason, many families are equipped with household air purifiers. At present, the commonly used household air purifiers are mostly filter-type purifiers. This filter-type purifier uses a fan to draw air into the purifier, and then filters the air through a built-in filter. This filter-type air purifier generally uses a combination of HEPA filter, activated carbon filter, photocatalyst (cold catalyst, long-distance catalyst) and ultraviolet sterilization to treat the air, so as to filter dust, eliminate odors, and disinfect. . [0003] However, this kind of purifier has been used for a...

Problems solved by technology

[0003] However, this kind of purifier has been used for a long time, and the filter screen will gather some dust. In a humid environment, the filter screen will become moldy and hairy, and then evolve into a source of toxicity. When the air passes through the filter screen, toxic substances will be removed from the machine. Take it out, this will not only fail to purify the air but will aggravate air pollution, so the filter screen of the filter type purifier cannot be used for a long time, it needs to be changed frequently, it is inconvenient to use and the cost is relatively expensive
