Electrostatic air cleaner

Abstract

The invention provides an electrostatic air cleaner which comprises an electric charge cavity (10), an electric charge module (30) and a dust removal cavity (20). The electric charge cavity (10) is provided with an air inlet (50) allowing air to flow in; the electric charge module (30) is arranged in the electric charge cavity (10) and used for enabling solid particles in air to be loaded with negative electricity; the dust removal cavity (20) is communicated with the electric charge cavity (10), and a dust collecting unit (200) is arranged in the dust removal cavity (20); the dust collecting unit (200) comprises a plurality of dust collecting plates (1) and a plurality of high-pressure plates; the multiple dust collecting plates (1) and the multiple high-pressure plates are arranged in a staggered manner; each dust collecting plate (1) and the adjacent high-pressure plate are spaced by a stipulated distance, and a dust removal electric field is formed; and each high-pressure plate comprises an electric conduction polar plate (3) and insulation plates (2) located on the two sides of the electric conduction polar plate (3).

Description

technical field [0001] The invention relates to an air purifier, in particular to an electrostatic air purifier. Background technique [0002] With the advancement of industrialization, more and more serious air pollution is threatening the physical and mental health of the people. Therefore, the market urgently needs air purifiers that can effectively remove particulate matter. At present, the commonly used air purifiers are mostly filter purifiers and electrostatic precipitator purifiers. [0003] The filter type purifier uses a fan to draw air into the purifier, and then filters the air through the built-in filter. This filter-type air purifier generally uses a HEPA filter to absorb particulate matter in the air. However, after this kind of purifier is used for a long time, the filter screen will gather some dust, and the filter screen will become moldy and hairy in a humid environment, which will become a source of toxicity. When the air passes through the filter scree...

Problems solved by technology

[0005] 1) Ozone is easily broken down between two adjacent metal plates

[0006] 2) In order to minimize the probability of the air between the metal plates being broken down, the distance between adjacent metal plates is generally increased (generally greater than 5mm) or the potential difference is reduced (less than 5000V), which causes an electric field The strength is weak, the metal plate cannot absorb all the charged particles at one time, and the purification efficiency at one time is reduced

In addition, positively charged particles will overflow with the wind, and the positive ion environment accumulated to a certain concentration is harmful to the human body
