Description of the Related Art In recent years, oil spill accidents from tankers and the like are increasing, and a large amount of oil is spilled into the sea from an oil shipping port in the Gulf War. Is attracting attention. The recovery method is the processing by an oil recovery ship (only capable of recovering oil water together and separating oil water by specific gravity difference, centrifugal separation, etc.),
A method of collecting oil-water mixture as it is on a barge ship using float suction etc. to transfer oil floating on the sea surface and transferring it to the land to separate oil-water, or spreading an oil fence in the oil spill area, Hisashiku, adsorption mat, etc. A method is known in which primary recovery is performed by human sea tactics using, and then a neutralizing agent is sprayed. However, the oil that spilled over the sea forms an extremely thin oil film on the sea and also has waves, so it is not possible to recover only the oil film portion of the surface, and it is not possible to recover the oil-water mixture. The oil content is less than 5%, and it contains oil, seawater, and various kinds of dust. Therefore, since the oil is collected and the oil content is adjusted to 10 ppm or less, or 5 ppm or less, the use of a delicate separation member makes it difficult to increase the overall processing capacity, and the capacity is reduced early due to dust and the like. There is a difficulty of doing. Also, when water containing oil is sucked in with a pump, the oil is emulsified due to the pump process,
Subsequent oil-water separation is difficult. Such problems also exist when treating the wastewater accumulated in the treatment pond in the factory or the water accumulated at the bottom of the oil tank.

The oil-water separators according to the first and second inventions can be moved anywhere by being placed on a vehicle such as a car, a freight vehicle, or an automobile, and thus are extremely useful for preventing oil leakage. When the vehicle is an automobile, it is very convenient for treating water accumulated at the bottom of a large number of crude oil storage tanks. In order to treat the water that has accumulated at the bottom, it is possible to treat it at the tank base compared to the case where the water and oil are separated by static stirring after being pumped and transferred in an emulsified state. It is very advantageous because it can be used up and transportation cost can be reduced.

の構造にしておくことが好ましい。When arranging the corrugated plates on the baffle plate block at a constant interval, the interval can be arbitrarily selected in the range of usually 1 to 100 mm, but this value changes depending on the size and shape of the crests of the corrugated plate. It is natural to do. The perforated plate is usually a plate provided with a large number of holes having a diameter of 4 to 20 mm, preferably 8 to 12 mm, and the porosity is preferably 30 to 75%, particularly preferably 55 to 65%. The oil / water / air mixture impinges on this plate, so that most of the air is separated here, while at the same time the perforated plate also acts as a primary filter for dirt. It goes without saying that the baffle plate block functions as a secondary filter, but the floating oil droplets collide with the baffle plate and move to promote the coarse particle ratio. A synthetic resin is usually preferable as a material forming the baffle block and the perforated plate, but a metal material or the like can also be used. For example, polypropylene, polyethylene, polyvinyl chloride, stainless steel, carbon steel, etc. can be illustrated. The baffle block and the perforated plate will be clogged with dust and the like, and the flow rate will drop. Therefore, it is necessary to check the flow meter and replace the baffle block and the perforated plate from time to time. Therefore, it is preferable that the baffle block and the perforated plate have a removable structure such as a cartridge type.

This prevents fluctuations in the oil-water interface due to air in the first separation column, ensures accurate oil removal work, and completely separates the mixed air in the first separation column. It has the function of preventing the oil separation performance from decreasing and stabilizing it.

交換できるよう着脱自在としておくことが好ましい。Although the treated water obtained by the first separating means alone is almost transparent to the naked eye, it is preferable to treat the treated water by the second separating means in order to completely separate the oil content. . The oil content that has not been removed by the first separating means can be reduced to 10 ppm or less by passing through the second separating means. A large number of holes are provided in the cylindrical body forming the second separating means, and the shape of the holes may be a circle, an ellipse, or a polygon, but in the case of a circle, the diameter is 2 to 10 mm, especially about 4 to 8 mm. preferable. In the case of a square, one side is preferably about 3 to 8 mm. The porosity is usually 30 to 75%, preferably 55 to 6
5%. A synthetic resin, a metal, or the like can be used as a material forming the cylindrical body. Specific examples include stainless steel, carbon steel, polypropylene, polyvinyl chloride and the like. As the filter material, a molded product made of glass fiber, polypropylene fiber, nylon fiber or the like, or a woven fabric, a non-woven fabric, a mat or the like of which is sprinkled to a predetermined thickness is used. Since such a separation cylinder also becomes clogged with the filter material due to continuous use, it is preferable to be detachable so that the separation cylinder can be replaced according to the value of the differential pressure gauge.
