A condensation dedust-demister device, comprises at least one of the followings: a condensator, a refluent demister, a large curve demister, a mixed curve demister and a super-sine demister etc.. Said condensator with a shell/cavity style pipeline refrigerating system or cooling system can condense dust into mist/haze and be designed as the first class tube demister, consequently said refluent demister and so on can collect and dedust-demist what condensator condensed by centrifugal effect, with the assisting of easiness made by collecting liquid wall and drain as well as multiple classes composition the condensation dedust-demister set can dedust flue gas to 0 mg/Nm3 and demist to 10 mg/Nm3 when raw gas containing dust less than 20 mg/Nm3. This set can remove grains of SO3 aerosol and Hg0 etc. due to be condensed to haze at the same time.

An internal combustion engine provided with an engine body, a filter provided in an exhaust passage of the engine body and trapping PM in the exhaust, and an aggregating device charging PM in the exhaust flowing into the filter to make it aggregate. The control device for controlling the internal combustion engine is provided with a PM charging control part controlling the amount of charging of the PM in the exhaust flowing into the filter. The PM charging control part controls the aggregating device so that the amount of charging of the PM becomes smaller when the amount of PM buildup of the filter is large compared with when it is small.
