Open type electrostatic floating dust adsorption plate air purifier

Abstract

The invention provides a novel device for directionally and intensively precipitating and purifying air by utilizing an electrostatic field. The device is composed of a main machine shell, a columnarfloating particle negative charge electric appliance and a positive potential dust collecting plate. A high-voltage direct-current power supply is arranged in the main machine shell, and the positivepole is connected with the dust collecting plate to form a positive polarity electrostatic field to generate electrostatic attraction force. The negative electrode of the high-voltage power supply isconnected with the floating particulate matter negative charge electric appliance, and the charged electric appliance can carry out a negative charge on the particulate matters floating in the air. The floating particulate matters in the air have the upward and negative charges and are attracted by the electrostatic field, and directionally and intensively adsorbed onto the dust collecting plate with the positive electric field, so that the effect of purifying air is achieved.

Description

Technical field: [0001] The invention relates to a purifier technology with an open floating dust electrostatic adsorption screen. Background technique: [0002] There are two types of purification methods for household air purifiers in the existing air purification technology: filter screen filter type air purification technology and tunnel type electrostatic dust collection air purification technology. Both of these home air purification technologies have serious flaws: [0003] 1. Defects of filter screen household air purification technology: household air purifiers are required to purify micron-sized suspended particles (pm2.5) in indoor air that are harmful to human body, and the aperture (mesh) of the filter screen cannot be micron level, so it cannot filter out micron-sized pm2.5 particles. Although the attached dust can be seen, the attached dust is not firm, and it will be blown off by the wind, forming a "secondary flying" and re-released into the indoor air. S...

Problems solved by technology

[0003] 1. Defects of filter screen household air purification technology: household air purifiers are required to purify micron-sized suspended particles (pm2.5) in indoor air that are harmful to human body, and the aperture (mesh) of the filter screen cannot be micron level, so it cannot filter out micron-sized pm2.5 particles

Although the attached dust can be seen, the attached dust is not firm, and it will be blown off by the wind, forming a "secondary flying" and re-released into the indoor air

Some manufacturers add multi-layer filters to overcome the "secondary flying", which increases the wind resistance, consumes more power, and increases the noise, which cannot eradicate the disadvantages of "secondary flying"

It is also necessary to constantly replace the filter screen for secondary consumption. It is troublesome to maintain the filter screen during use. The filter type household air purification products are of no use value.

[0004] 2. Defects of tunnel-type household electrostatic dust collection air purification technology: To achieve electrostatic dust collection and air purification, suspended particles must be extremely dry to be firmly absorbed by the dust collection plate. The indoor humidity cannot be absolutely dry, and particles cannot be adsorbed firmly by electrostatic adsorption There is no use value if there is a "secondary flying"
