Zusammenfassung: | The utility model discloses an efficient chimney with the functions of corrosion-prevention, dust-collection and energy conservation, and relates to a chimney with the functions of corrosion-prevention, dust-collection and energy conservation, which comprises a chimney cylinder body (3), and is characterized in that an inner bore helical line (1) with a helix angle ranging from 10 to 80 degrees is arranged on the inner lining wall of the chimney cylinder body (3); an outlet (2) of a smoke flue (4) outside the lower end of the chimney cylinder body (3) is connected with the inner bore helical line (1); and the smoke flue (4) is in smooth connection with the inner bore helical line (1). Compared with the prior chimney, the utility model has the advantages of stable structure, good environment-friendly effect, prolonged service life and relatively low manufacturing cost, can improve the environment-friendly effect by 25% to 45%, can reduce the self-resistance by 20%, and therefore can reduce the power consumptio |
