Description

  The present invention allows oil-containing water containing oil, sludge, and the like generated on the road surface to flow from a collecting culvert through a culvert and separate and remove them, and the oil-water separating culm can be installed outside the ground. Regarding the installation structure.

  Oil and sludge substances are generated on the road surface in addition to rainwater, and an oil / water separation facility is provided for the purpose of removing them from the viewpoint of reducing environmental impact or preventing accidents. Various substances such as sludge substances carried by cars or scattered from the surroundings and oil generated from accidents or asphalt are generated as oil-containing water on the road surface, and these are generated from the road surface to side ditches and catchment basins. In order to prevent them from flowing out and being discharged as they are, oil and water separation facilities are installed at predetermined intervals on the road to remove oil and sludge, etc. There is a foundation on the ground and installed on it.

  The same is true for highways based on bridges, and oil-water separation facilities are constructed and installed on the ground around the pier foundation under the bridge. However, there are many places where it is difficult to construct the ground around the pier foundation due to a steep slope such as a mountainous area or some obstacles, and in such cases the installation was postponed .

  Further, the shape of a conventional oil / water separation facility is divided into four compartments by a plurality of partition plates C, D, E, and the oil water in the direction of arrow A, as in the oil / water separator of FIG. There is one in which filters F, G, H, and I made of a hydrophilic oil adsorbent that forms a flow of mixed water and absorbs oil are provided in each of the four sections.

  The oil / water separation layer main body B is provided with an inlet J for oil / water mixed water, but the opening end thereof is stored in a first section partitioned by a partition plate C into which the oil / water mixed water flows. Facing the oil / water mixture, the oil / water mixture flowing in from the inflow pipe is directly flown into the stored oil / water mixture, and the previous oil / water mixture is agitated, especially when a large amount of oil / water mixture flows in. It will also have a big wave effect on this section.

  As a result, what was separated into oil and water in the compartment was agitated into the original mixed state, which was a factor that significantly impeded the oil-water separation function.

  Further, as described above, when a large amount of oil / water mixed water flows in, a large fluid load is generated in the oil / water separation layer main body, so that the main body needs to be constructed and installed with a heavy weight.

  The present invention solves the drawbacks of the conventional example described above, and is provided with means for reducing the flow load of the oil water in the inlet end and the oil / water separation tank, so that even if a large amount of oil water flows in, the main body It is possible to reduce the weight of the main body by reducing the influence on the oil. By this weight reduction, the oil-water separation rod can be installed on the side wall of the pier head of the bridge outside the ground. Is.

The front view of the other Example of the oil-water separation tank of this invention is shown. Sectional drawing of the prior art example of an oil-water separator is shown.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1A is a plan side sectional view of the oil / water separator 1 of the present invention, FIG. 1B is an elevation side sectional view, FIG. 1C is a plan view of the outer side, and FIG. Show. Oil-containing water containing oil, sludge substances, etc. generated on the road surface of the road is allowed to flow into a cubic oil-water separator 1 made of FRP, which is a substantially hexahedron, to remove oil, sludge substances, and the like.

  The oil / water separator 1 has, for example, an oil storage amount of 600 L and a volume of water level capacity of about 1,100 L. An inlet 3 is provided above the front side wall 2, and oil, sludge substances, etc. are provided from the inlet 3. The oil-containing water containing water is allowed to flow into the oil / water separator 1.

  The inlet 3 is provided with a wave-breaking plate 3a which is closed at the front and sides and opened only at a position substantially orthogonal to the inflow direction of the oil-containing water, and a large amount of oil-containing water is vigorously separated. Even if they flow into the bowl 1, they will collide with the wave preventing plate 3a, the momentum will be greatly relaxed, and there will be no influence such as stirring the oil-containing water stored previously.

  The oil / water separator 1 forms a space partitioned by a plurality of partition walls. A first storage chamber 9 is formed by the front side wall 2, the front side wall 4, the back side wall 5, the bottom 6, the roof 7, and the first partition wall 8, and serves as a storage means for oil-containing water. A communication port 10 is provided at a lower position of the first partition wall 8 to relieve the fluid force of the oil-containing water, and the flow direction is directed upward by the first jammer plate 11 to become the next space portion. The first partition wall 8, the front side wall 4, the back side wall 5, the bottom 6, the roof 7, and the second partition wall 12 are made to flow into the second storage chamber 13.

  The first jammer plate 11 has a vertical direction on the second storage chamber 13 side between the front side wall 4 and the back side wall 5 at an opposed position close to the first partition wall 8, for example, with an interval of about 150 mm. The lower end side of the first partition wall 8 is less than half the height of the first partition wall 8, and the lower end of the first partition wall 8 is suspended from the upper end portion of the communication port 10, thereby setting the position smaller than the opening size of the communication port 10. The lower end side is an opening 14.

Moreover, the protrusion 21 which protruded toward the 2nd partition wall 12 side can be provided. The arrangement interval and height with the second partition wall 12 are the same as those of the first jammer plate 11.

  A protrusion can be provided on the lower end side of the first, second and third partition walls 8, 12 and 18 to prevent the sludge material and the like from rising.

  Similarly to the above, a communication port 22 is provided at a position below the third partition wall 18, and the third partition wall 18, the front side wall 4, the back side wall 5, the bottom 6, the roof 7, and the rear side wall 23. Thus, a discharge tub 24 is formed. An outlet 25 is provided in an upper part of the rear side wall 23.

  The outlet 25 is formed at a position having an opening core in the center of the oil-water separator 1 in the short direction, which is the same as the position of the inlet, and the center positions of both are the same. In addition, since both the heights are the same height and the size of the opening is the same, even if the front side wall 2 is reversed and used as the back side wall 5, it is connected to them. Therefore, it is possible to promptly install without changing the position of the vertical gutter, side gutter or inclined gutter.

  A sediment processing cleaning port 26 that also serves as a drainage port for cleaning is provided at a lower portion of the rear side wall 23 of the discharge basin 24, and the first storage chamber 9, the second storage chamber 13, and the third storage chamber 19.
