FILTER PIECE COLLECTING DEVICE FOR EXHAUST EMISSION CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent discharge of ceramic fiber pieces scattered in exhaust gas from a ceramic fiber-made filter into the atmosphere. SOLUTION: The filter piece collecting device 13 comprising a swirl generating means 14 generating a helical swirl in the exhaust gas (a) and a filter piece collecting means 15 collecting the ceramic fiber-made filter pieces (b) scattered in the exhaust gas (a) is installed in a downstream of the exhaust emission control device 1 arranged in an exhaust system of a diesel engine 50 and heating and incinerating particulates included in the exhaust gas (a) by collecting them by the ceramic fiber-made filter 4.
