Embodiment 1

[0024] at 20m 3 In the room, the organic pollutants in the air are mainly trace formaldehyde (0.06mg / m 3 ) can cause respiratory discomfort in children; PM2.5 content is 0.04mg / m 3 , there is a certain amount of inhalable particulate matter. Turn on the electrostatic precipitator, the air containing dust and formaldehyde enters the electrostatic precipitator with the airflow of the exhaust fan, guided by the metal plate hole and the corona pole fairing, the airflow converges within the range of 2-5cm near the corona pole and the dust particles Will not stick to corona electrodes. In the spaces on both sides of the corona electrode covered with needle-punched thin conductor rods, since the air is more easily ionized in the direction of the needle-punched tip, the negative ions are more concentrated and move faster on both sides of the corona electrode. And adopting the layout method facing the airflow improves the probability of collision charging between dust and negatively...

Embodiment 2

[0026] The interior of a small car, especially with the windows open and exposed to the hot sun, will greatly increase the content of formaldehyde and other organic pollutants and dust. The detected formaldehyde content is (0.12mg / m 3 ) greatly exceeded the national standard, and the PM2.5 content was also 0.11mg / m 3above. These organic pollutants and dust are inside the car and cannot be dispersed for a long time due to the limitation of ventilation conditions. However, the space in an ordinary household car is small, so it is not suitable for an ordinary household air purifier. The invention can be placed at the rear of the handbrake or the rear seat of the household car, does not occupy limited seating space, and does not affect the driver's vision and operation. The dust-laden and formaldehyde-containing air enters the electrostatic precipitator with the airflow of the exhaust fan, and is guided by the metal plate hole and the corona pole fairing. dizzy extremely. In ...

Abstract

The invention relates to a multifunctional air purifying device. The multifunctional air purifying device comprises an ionization part, a dust collection part (3) and an ozone elimination part (4) which are arranged in sequence. The ionization part is composed of corona electrodes (2) and a metal plate with porous channels (1). The corona electrodes (2) are placed in the middle of the metal plate with the porous channels (1). The dust collection part (3) is a parallel strong electric field dust collection part formed by alternately arranging honeycomb activated carbon electrodes (5) and hollow plastic plates (7). The ozone elimination part (4) is arranged behind the dust collection part (3). Compared with the prior art, the electrostatic dust collection device is small in size, capable of removing dust particles and organic pollutants such as formaldehyde and also composed of eliminating ozone generated by an electrostatic generation device.

Description

technical field [0001] The invention relates to a multifunctional air purification device, which can realize the adsorption of PM2.5, formaldehyde and other organic substances in the air at the same time. Background technique [0002] Electrostatic dust removal technology is favored by people as a mature and mainstream dust removal technology in industrial production and daily life. A large number of air purifiers using electrostatic precipitator technology or related improved technologies have attracted the attention of consumers. However, the electrostatic dust removal technology itself has some defects, which restrict its effect in actual use. The corona electrodes of traditional electrostatic precipitators are simple metal wires or metal needles, which are either suspended in the air channel or placed along the direction of air flow. Because the corona electrode will ionize the surrounding gas molecules when it is connected to high voltage, forming a corona area, there...
