Air filtering device based on rough effect filter screen

Abstract

The invention discloses an air filtering device based on a rough effect filter screen, and belongs to the field of indoor air purification. The device comprises a metal plate with a hole, a metal discharge filament, the rough effect filter screen and a metal net which are arranged in an openable insulating shell port area along an air flowing direction in sequence, wherein a positive polarity output power supply is arranged in a non-runner area of an openable insulating shell; a positive electrode of the power supply is connected with the metal discharge filament; an earth electrode of the power supply is respectively connected with the metal plate with the hole and the metal net; the rough effect filter screen is detachably connected with the openable insulating shell by a fixed part. According to the device disclosed by the invention, through a particulate pre-charged part between the metal plate with the hole and the metal discharge filament and a rough effect filter screen polarity part between the metal discharge filament and the metal net, the filtering efficiency of a single layer of rough effect filter screen is enhanced. The device has a simple structure and small occupied space, and provides a way of long-term realization of low-resistance high-efficient removal of indoor particulates.

Description

technical field [0001] The invention relates to an air filter device based on a coarse-effect filter screen, which belongs to the technical field of indoor air purification equipment. Background technique [0002] With the rapid development of my country's economic construction, it has also brought a serious burden to the environment. PM in my country's cities 10 and PM 2.5 Concentrations are much higher than the world average. [0003] A large number of studies have shown that particulate matter can have many negative effects on human health, including: allergic reactions caused by pollen or other dust, infections caused by bacteria and fungi, irritation of mucous membranes by acid and alkaline substances, and deposition of particulate matter in the human body Long-term damage to lung function, the poisonous effect of particulate matter absorbed by the blood on the human body, the deformation of muscle fibers caused by asbestos, quartz, etc., the carcinogenic effect of ch...

Problems solved by technology

[0008] In order to overcome the disadvantages of the prior art, such as large resistance, small dust holding capacity, and reduced efficiency after a period of use, the present invention provides a non-powered air filter with a special structure for pre-charging of particles and polarization of the filter screen. Filter device, the filter adopts a single-layer coarse-effect filter, which can achieve long-term low resistance and high-efficiency removal of particulate matter, and occupies a small space
