Document Type and Number:
Japanese Patent JP2023106800
Kind Code:
A
Abstract:
To provide a processing device, a processing method and an exhaust gas treatment system capable of appropriately determining timing of filter cleaning.SOLUTION: A processing device includes: an acquisition section acquiring information indicating an estimation value of accumulation amount of ash accumulated in a filter collecting particulate matters in exhaust gas of an engine and information indicating atmospheric pressure; a calculation section calculating an allowed ash accumulation amount threshold value corresponding to allowed ash accumulation amount changing in accordance with the atmospheric pressure; a determination section determining that cleaning of the filter is necessary when the estimation value is the allowed ash accumulation amount threshold value or larger; and a reporting section that when the necessity of the cleaning of the filter is determined, reports the determination result.SELECTED DRAWING: Figure 2
