<p>PURPOSE:To provide an exhaust gas processing device of such constitution as to select a filter, corresponding to the grain diameter of particulates, out of filters with different pore diameters and to collect particulates by the selected filter. CONSTITUTION:Plural filters 2A, 2B, 2C with different pore diameters are disposed parallelly in the width direction in a casing 1. Dampers 3A, 3B, 3C provided at the respective exhaust gas inlets 6A, 6B, 6C of the filters 2 can be opened/closed independently, and the filter 2 with the optimum pore diameter corresponding to the exhaust gas temperature detected by a temperature sensor 9 is selected by a controller 10 to collect particulates. Excessive pressure loss rise is not therefore generated to the filter 2 so as to be able to collect particulates efficiently over many hours.</p> |
