A method for removing fine particles in the air under home environment conditions

Abstract

The invention relates to a method for removing fine particulate matters in the air under the condition of home environment, belonging to the field of purifying treatment. A positive and negative high-voltage pulse charged area, an electrostatic coagulation area under the alternating electric field, a dust particle collection area, a plasma sterilization area and a negative ion area are sequentially arranged in an air channel; in the positive and negative high-voltage pulse charged area, the air to be purified is divided into two parts which are respectively introduced into particle charged areas, and the particle charged areas respectively have the positive and negative charges and are arranged in parallel, so that the positive and negative charges are respectively carried by the particles in the two parts of air, and charge particles can be formed; under the action of alternating current (AC) high-voltage or pulse AC high-voltage field, the positive and negative charge particles have motion collision with one another, and larger particles are coagulated; when passing through the dust particle collection area, the larger-particle dust is collected onto a grounding dust collection plate, so that the fine particulate matters in the air can be purified. After the method is used, in the home environment, the collection efficiency of the fine particulate matters with the particle sizes of less than 10mu m reaches more than 90%.

Description

technical field [0001] The invention belongs to the field of purification treatment, and in particular relates to a method for removing fine particles in air by means of high-voltage electric field separation. Background technique [0002] Recently, due to the excessive emission of various industrial smoke and dust, and the rapid increase in the number of cars in the society, the air pollution is increasing day by day, the air quality of the surrounding environment is rapidly decreasing, and the number of smog weather has increased significantly, making indoor air filtration and purification devices application market is growing. [0003] As an adsorption, cleaning, and purification device for air dust in indoor or car spaces, various indoor or vehicle-mounted air purification devices have been used, and various air purifiers are widely used in hotels, commercial office buildings, airport waiting halls, and carriages. , cabins and other occasions that require air purificati...
