摘要：
The invention relates to an exhaust gas purification device that effectively detects an amount of ash collected and accumulated in a DPF. The exhaust gas purification device includes the DPF (16) for collecting PM contained in an exhaust gas, forced regeneration units (13, 25) capable of performing forced regeneration, capacitance detection units (17a, 17b, 21) for detecting a capacitance of the DPF (16), a total accumulated amount estimation unit (22) for estimating a total amount of accumulated PM and ash collected in the DPF (16) on the basis of the detected capacitance, and an ash accumulated amount calculation unit (23) for calculating an amount of accumulated ash by using, as the amount of accumulated ash, the total amount of accumulation which is estimated when the forced regeneration finishes.
