Air purification unit applicable to remove fine particles in the air in the home environment

Abstract

The invention relates to an air purification unit applicable to remove fine particles in the air in the home environment and belongs to the field of electrostatic dust removal. The device comprises an air inducing unit, an air purification unit and an air channel. The air purification unit comprises a positive high-voltage pulse charge region, a negative high-voltage pulse charge region, a static coagulation region under an alternating electric field, a dust particle collection region, a plasma disinfection region and a negative ion region which are arranged successively. A narrow-pulse discharging mode and a negative direct-current high-pressure discharging mode are used, a working voltage below 30KV and a working current below 10mA are used, and the collection efficiency of more than 90% of particles with diameters below 10 microns is achieved in the home environment; the problems of over-large 'wind resistance' and 'secondary pollution' of prior home air conditioners are solved, fine particles in the air can be removed in the home space size range, the air can be disinfected, and the problem of ultraviolet light leakage harms is solved.

Description

technical field [0001] The invention belongs to the field of electrostatic dust removal, and in particular relates to an air purification device for removing fine particles in the air by means of an electrostatic field. 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 ...

AI Technical Summary

Problems solved by technology

[0019] The technical problem to be solved by the present invention is to provide an air purification device suitable for removing fine particles in the air under household environmental conditions. ≤500μg / m 3 , PM10≤600μg / m 3 For the home environment, the narrow pulse discharge form and the negative DC high voltage discharge form are adopted, and the working voltage below 30KV and the working current below 10mA can achieve a collection efficiency of more than 90% for particles with a particle size below 10μm; it solves the current problem There are problems of excessive "wind resistance" and "secondary pollution" of household air purifiers. It can not only achieve the purpose of removing PM2.5 particles in the air within the size range of the home space, but also disinfect the air and avoid the damage of ultraviolet radiation. spill damage problem
