| 摘要 |
<p>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.</p> |
