<p>PROBLEM TO BE SOLVED: To simultaneously remove tacky substances and malodorant components in exhaust gas by pre-forming an adsorbent layer of a desired thickness in the primary side of a filter cloth by feeding to a bag filter an adsorbent of an average particle size of a specific value and clean air and after then feeding exhaust gas to the bag filter. SOLUTION: An adsorbent comprising, for example, active carbon powder of an average particle size of 1-100 micron meter, preferably 1-approximately 30 micron meter is charged into an adsorbent feed hopper 5. The adsorbent is fed to an exhaust gas duct P1 through an adsorbent feed pipe 7 by the suction force of an exhaust fan F and the feed of high-pressure air, and also is fed into a bag filter 1 after being mixed with clean air through an air introducing pipe 4, and is sticked on the primary surface of a filter cloth 2 to form an adsorbent layer of a desired thickness. Then, the exhaust gas containing resin components and malodorant components is fed into the bag filter 1. The exhaust gas is exhausted into the atmosphere through an exhaust gas duct P2 after passing through the filter cloth 2, tacky substances are sticked on the near- surface place of the adsorbent layer, and the malodorant components are adsorbed in the adsorbent to be removed.</p> |
