Novel low-resistance high-efficiency air filter and purification air conditioner thereof

Abstract

The invention particularly discloses a novel low-resistance high-efficiency air filter which comprises a frame body, corona electrodes arranged in the frame body in a front-back spaced mode in the air flowing direction, an electric charge electrostatic fiber layer, an electret electrode tightly attached to the electric charge electrostatic fiber layer and an earth electrode. The corona electrode is composed of a plurality of wires electrically connected with a power supply, and corona is generated when the corona electrode is electrified, so that dust particles in flowing air are negatively charged; the electret electrode continuously charges the electric charge electrostatic fiber layer when being electrified, so that the electric charge electrostatic fiber layer is continuously positively charged; the electric charge electrostatic fiber layer filters air through physical interception and electrostatic adsorption. The invention further discloses the purification air conditioner. The novel low-resistance high-efficiency air filter and the purification air conditioner thereof have the air filtering effects of low resistance, high efficiency, stable filtering performance and no generation of ozone, and are simple in structure, good in adaptability and convenient to install and maintain.

Description

technical field [0001] The invention relates to an air filtering device, in particular to a novel low-resistance high-efficiency air filter and a purification air conditioner including the low-resistance high-efficiency air filter. Background technique [0002] Due to the pollution of the external natural environment itself and the influence of indoors that require air circulation replacement, such as indoor public places, offices and family occasions, especially special occasions with hygienic standards such as hospitals, pharmaceutical factories, food factories, air and air conditioners A large number of dust particles and bacteria and other microorganisms are collected in the system or air circulation system, which become an important source of air pollution in these occasions. Therefore, air filtration and purification must be carried out. And through the impact of airborne viruses such as the new crown epidemic, people's health awareness continues to improve, and the n...

AI Technical Summary

Problems solved by technology

However, if the gap between the dust collecting electrodes is too large, tiny particles cannot be adsorbed, resulting in low purification efficiency; and if the gap is too small, it will cause discharge and generate ozone.

Therefore, limited by the physical gap between the dust collectors, it is impossible for this electrostatic precipitator filter to achieve both high efficiency and ozone-free

In addition, this electrostatic dust filter has a filtration efficiency of less than 50% for 0.3μm particles, and the filtration efficiency is greatly affected by the nature of the particles and temperature and humidity, and the performance is not stable enough.

In addition, the thickness of this electrostatic precipitator filter is generally about 200mm, and all materials are made of metal, which will cause defects such as large volume, heavy weight, and inconvenient installation and maintenance.
