<p>PROBLEM TO BE SOLVED: To provide a device for treating harmful components in waste gas which is easy to work and manufacture and in which the collecting efficiency of fine dust adsorbed inside a chamber is improved and also the driving part for deriving a scraper is easy to control and which is economical. SOLUTION: This device includes a hopper like chamber 64, a lower guide cylinder 65 connected to the lower end of the chamber 64, a collection guiding part 120 fixed to the lower guide cylinder 65 for guiding deposition to the edge part of the lower guiding part 65, and a scraper rotation part 110 for scraping out fine dust adsorbed on the chamber and the collection guiding part by its rotation. The scraper rotation part 110 includes a scraper rotation gear 101 installed in the lower guide cylinder 65, and a power transmission gear 102 engaged with the scraper rotation gear 101 through an opening formed on the side face of the lower guide cylinder 65.</p> |
