EXHAUST EMISSION CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an exhaust emission control device capable of suppressing heat radiation from a casing which accommodates a particulate filter.

SOLUTION: The device is equipped with an exhaust inflow part 50 into which exhaust of an engine 1 flows; a first casing 46 having a downstream end opening 52 through which the flowed in exhaust flows out; a second casing 48 which is formed in a cylindrical shape with both ends open to accommodate a particulate filter 38, whose upstream end opening 54 is detachably coupled to the downstream end opening 52 of the first casing 46 via a first flange 60 and second flange 62, and includes an exhaust outflow part 58 through which exhaust passing through the particulate filter 38 flows out in a side wall part 56 situated on the downstream side from the particulate filter 38; and a lid member 70 which is detachably mounted to the second casing 48 via a third flange 72 and fourth flange 74 and which blocks a downstream end opening 68 of the second casing 48.
