Air purification device

Abstract

The present invention relates to an air purification device. The present invention comprises: a purifying member for adsorbing and purifying gaseous pollutants contained in the air introduced from the outside; and a desorption means for decomposing and desorbing the gaseous pollutants adsorbed on the purifying member, by microwave heating, wherein the purifying member comprises: an adsorbent for adsorbing the gaseous pollutants; a dielectric substance for absorbing the microwave; and an oxidation catalyst for oxidizing the adsorbed gaseous pollutants. According to the present invention, the gaseous pollutants contained in the polluted air introduced from the outside are continuously or intermittently adsorbed, desorbed and purified, and thus, the purifying member can be regenerated. Thus, the present invention has an effect of sustainedly maintaining adsorption efficiency of the purifying member and, at the same time, greatly improving the lifetime thereof.

Description

technical field [0001] The present invention relates to an air cleaning device, and more particularly, to an air cleaning device capable of greatly improving the efficiency of cleaning gas pollutants contained in air entering from the outside. Background technique [0002] In general, air purification devices are widely used as a means of treating pollutants such as bacteria, odors, volatile organic compounds, or harmful components to provide a pleasant gas atmosphere for homes, multi-purpose facilities, or industrial places. [0003] An air cleaning device with this characteristic is mainly composed of a plurality of filters for treating particulate matter such as dust or bacteria, and a deodorizing filter for treating gaseous pollutants such as odors, volatile organic compounds, and harmful components. As a filter for treating particulate matter, a filter utilizing the sieving effect of particulate matter and a dielectric electrostatic filter utilizing static electricity a...

In addition, static adsorption filters do not have internal regeneration capabilities, so their service life is limited

[0006] In addition, the ozone oxidation filter using ozone is a system that uses the ozone oxidation ability, so although the ozone oxidation filter can be used for a long time without replacing the filter, ozone is an environmental pollutant, and when unreacted ozone Ozone oxidation filters can cause asthma, allergies and more when vented to the outside
