| 摘要 |
The present invention relates to a funnel drain tank placed in a ship, which comprises a tank main body whose inside is empty and where an inlet is installed in the upper part thereof; an inducing pipe which is uprightly installed at one side of the tank main body so that water inside the tank main body can flow in and move upward; a draining pipe which is installed in the upper part of the inducing pipe so that the top thereof can communicate with the inducing pipe in order to discharge the water to the outside; and an oil discharging pipe which is connected with one side surface in the upper part of the tank main body. Therefore, the funnel drain tank can prevent sea contamination by separately discharging rainwater and oil flowing inside the tank main body due to a difference in specific gravity. |
