Abstract
An exhaust gas purifying system includes a differential pressure detector that detects a differential pressure between an inlet/outlet of a filter, a flow rate detector that detects a flow rate of exhaust gas in the filter, a differential based-deposition-amount calculator that calculates a differential-based deposition amount of particulate matters in the filter based on detection results of the differential pressure detector and the flow rate detector, a regeneration temperature setting unit that sets a regeneration processing temperature of the filter based on the calculated differential-based deposition amount, and a regeneration processing unit that performs a regeneration processing of the filter based on the set regeneration processing temperature. The regeneration temperature setting unit sets a first regeneration processing temperature at a start of the regeneration processing and a second regeneration processing temperature higher than the first regeneration processing temperature when the differential-based deposition amount falls at or below a predetermined threshold.
