The top of the container 1 (its bottom is concave) is sealed with a lid 3 via a bag 2. An L-shaped outflow pipe 4 is inserted approximately in the center of the bottom of the container 1. The portion where the outflow pipe 4 penetrates the container 1 is configured to be watertight. There is a slight gap between the tip 41 of the outflow pipe 4 and the container 1. An inflow pipe 5 is connected to the side of the container 1. It is also preferable that the angle θ between the inflow pipe 5 and the container 1 be substantially tangential to the container 1, that is, 90 degrees. Or preferably at least 45 degrees or more.Next, the operation of the device according to the present invention configured as described above will be explained.

タ３をあけて排出される。 The wastewater containing oil flows through the inflow pipe 5 into the container 1.
Flow inside. Since the inflow pipe 5 is connected in the tangential direction of the container 1, the waste water flows inside the container 1 along the cylindrical side wall while having a rotational force in the direction of the arrow X. The drainage is then directed towards the bottom of the container 1 under the influence of gravity. At the same time, the initial velocity from the inlet pipe gradually slows down due to the friction between the oil and the side wall. Conventional centrifugal separators that utilize the difference in specific gravity between oil and water and centrifugal force (for example,
61378), its bottom is flat, so when the drainage water reaches the bottom, it will cause friction between the oil and the bottom.
The rotational speed of the wastewater drops significantly, and the separation effect due to centrifugal force cannot be expected. On the other hand, since the bottom of the present invention is bowl-shaped (that is, the bottom is concave), the effect of gravity and the radius of the bottom are small, so the rotational energy of drainage is Although it becomes smaller due to the friction between the drain and the bottom, the rotation speed of the drain does not drop significantly. As can be seen from the fact that centrifugal force is expressed as v 2 /r (v is rotational speed, r is radius), the smaller the radius, the greater the centrifugal force obtained even at the same speed. Even during the helical flow at the bottom of the container of the present invention (in conventional equipment, when the wastewater reaches the bottom, its rotational speed is almost 0 and no centrifugal force is generated), the oil and water are separated by centrifugation. Separated by force.
That is, moisture with a high specific gravity flows from the outer wall side of the container 1 to the bottom, is pushed out through the tip 41 by the outflow pipe 4, and is then discharged to the outside. Then, the waste water that is not completely drained and accumulates in the container 1 is accumulated with the oil on top and the water on the bottom. Even in this stationary state, since the bottom is bowl-shaped, there is almost no oil at the tip of the outflow pipe 4, and what is discharged from the outflow pipe 4 is water. Furthermore, when the next time the wastewater flows in, the above-mentioned action is repeated and the water is drained from the outflow pipe 4. The oil accumulated in the container 1 is drained by opening the lid 3 at appropriate time intervals.
