Purification treatment device for diesel generating set

The invention discloses a purification treatment device for a diesel generating set. The purification treatment device for the diesel generating set comprises a water tank, a screen horizontally erected inside liquid of the water tank, an air-water separation board horizontally erected above the liquid face of the water tank, an exhaust pipe arranged on the upper surface of a tank body of the water tank and used for exhausting air in the water tank, and an air inlet pipe inserted into the liquid of the water tank. The air inlet pipe is communicated with a smoke exhaust pipe of the diesel generating set. By means of the structural design, after smoke released by a diesel engine is effectively cleaned and purified by the liquid in the water tank, the smoke is drained into the atmosphere, so that the tail smoke of the diesel engine is effectively purified. The purification treatment device for the diesel generating set is simple in structure, good in purification effect and low in operation cost.
