| 摘要 |
The present invention relates to an installation structure of a pre filter for an adsorption tower with increased filtration area, for an adsorption tower which includes a body comprising an air inlet; a suction fan forcibly inhaling air; a filtering material installed to have a certain space on the left and right from a space for air flowing inside the body; and a pre filter primarily filtering impurities having big particles. The installation structure can significantly reduce air resistance compared with an existing method having a single pre filter installed on the lower part of the filtering material, and maximizes the filtering area the pre filter has to increase filtering efficiency efficiently collecting such as impurities with big particles to have an effect of providing ideal purified air to the inside. |
