Background

At present, with the development of marine development, marine operation, fishery production and industrial development in coastal areas, marine environmental pollution is becoming more and more serious. In order to reduce the pollution of the exhaust gas and oil stain of equipment on the ship to the ship and the marine environment, a targeted treatment measure needs to be taken for a pollution source.

Among them, the crankcase of the ship engine has oil mist when ventilating, and if not properly treated, it will become a pollution source for the ship and the marine environment. The breather pipe of general engine crankcase all directly leads to above the chimney deck, encloses the oil groove with steel sheet preparation, and can in leading gas to the oil groove. However, since the oil tank is used for storing dirty oil in an open environment, the oil tank overflows in severe weather, and the risk of dirty oil leakage exists. And the oil of oil groove needs regularly clearance, and when adopting closed oil groove to collect sump oil through the draining pipe, still need solve ventilative problem. The existing mode is that air holes are directly led to the top of a chimney, the mode is simple and easy to operate, but the time is long, oil discharged by a main engine and a generator crankshaft device is bonded with soot, a water leakage port in the top of the chimney is blocked, the oil is flushed to a deck along with rainwater to pollute the deck, and the water leakage port of the deck is easily blocked. The oil diffuses everywhere, causing pollution to the ship and influencing the safety of sailors; even pollution to the sea.
