Description

Oil mist vent structure {OIL MIST VENT STRUCTURE}

The present invention relates to an oil mist vent structure. More particularly, the present invention relates to an oil mist vent structure capable of preventing the condensed oil mist from scattering and preventing contamination of the surroundings.

On the land storage facility or the oil tank of the ship, the oil is heated to maintain a high viscosity oil at a low point, and the mist which is spontaneously evaporated is discharged to the outside of the tank. In the vent structure where this oil mist is in contact with the low temperature outside, the condensation amount increases and the condensed oil mist is scattered to pollute the surroundings, and the ship is further regulated according to the marine pollution prevention code. In addition, since the oil mist mistaken may hit the high-temperature pipe and cause a fire, it is necessary to collect all of them.
