HARMFUL GAS REMOVING DEVICE

摘要

A harmful gas removing device capable of easily and securely removing contained in air supplied to an air duct, particularly, harmful gases causing offensive odor and VOC (volatile organic compound) gases such as formaldehyde, acetaldehyde, and benzene which are pointed out to have carcinogenicity, comprising a plurality of collecting parts disposed in the air duct at specified intervals and a cooling means for forming water film on the surfaces of the plurality of collecting parts by cooling the plurality of collecting parts. The device is characterized in that the harmful gases are adsorbed in the water film formed on the surfaces of the plurality of collecting parts by utilizing diffusion resulting from the concentration gradient of the harmful gases supplied between the plurality of collecting parts.
