Abstract
Provided is an exhaust gas processing device for a diesel engine which can carry out sufficient regeneration processing of a DPF. A DPF regeneration control section continues normal regeneration processing by a DPF regeneration control section when an accelerated regeneration starting operation section does not perform accelerated regeneration starting operation after notification of accelerated regeneration requiring information is started. The DPF regeneration control section prohibits the normal regeneration processing, and an accelerated regeneration re-requirement notification section starts notification of accelerated regeneration re-requiring information, when a PM accumulation amount estimate becomes equal to or higher than an accelerated regeneration re-requirement determination value J. Thereafter, the regeneration processing of the DPF is not carried out unless the accelerated regeneration starting operation section starts the accelerated regeneration starting operation to cause the DPF regeneration control section to carry out the accelerated regeneration processing by the DPF regeneration section.
