PROBLEM TO BE SOLVED: To provide an exhaust gas processing device for a diesel engine, which can carry out sufficient regeneration processing of a DPF.SOLUTION: A DPF regeneration control means continues normal regeneration processing by a DPF regeneration control means when an accelerated regeneration starting operation means does not perform accelerated regeneration starting operation S11 after notification of accelerated regeneration requiring information is started S8. The DPF regeneration control means 4 prohibits the normal regeneration processing S13, and an accelerated regeneration re-requirement notification means starts notification of accelerated regeneration re-requiring information S14, when a PM accumulation amount estimated value becomes equal to or higher than an accelerated regeneration re-requirement determination value J4. Thereafter, the regeneration processing of the DPF is not carried out unless the accelerated regeneration starting operation means starts the accelerated regeneration starting operation S16 to cause the DPF regeneration control means to carry out the accelerated regeneration processing by the DPF regeneration means. |
