Exhaust gas processing system

摘要

An exhaust gas processing system (10) is provided with a particle separating apparatus (20) capable of separating and removing particles contained in an exhaust gas from the exhaust gas, and disposed between a front and a back exhaust pipes (42, 43) forming the exhaust gas discharge line (41). The particle separating apparatus (20) comprises a gas vessel (21) defining a gas chamber (22) for receiving the exhaust gas containing particles and discharged through a rear end portion (42a) of the front exhaust pipe (42), and an exhaust gas guide member (31) disposed in the gas chamber (22) and having guide walls (32, 33) defining an internal space and provided with openings (34) by means of which the internal space communicates with the gas chamber (22). The guide walls (32, 33) are formed so as to guide the exhaust gas discharged into the gas chamber (22) through the rear end portion (42a) of the front exhaust pipe (42) so that the exhaust gas flows in vertical, whirling currents in the gas chamber (22). A particle receiving unit (28a) of a particle container (28) is connected to a particle discharge unit (26) of the particle separating apparatus (20). The gas contained in the particle container (28) is replaced with an inert gas by a gas replacing apparatus (60) before separating the particle container (28) from the particle separating apparatus (20). <IMAGE>
