TECHNICAL FIELD This invention relates to the colleter used for an oil-water separator, and especially the granulation | disassembly of the microparticles | fine-particles of the disperse oil in the oil contained in water is effectively or reliably granulated. It is related to the core of the collider, which can be separated into complete oil and water.

For example, in ships, sewage at the bottom of the sea is likely to contain some oil, and the discharge of this oil into the sea near the port or the coast is the United Nations Intergovernmental and Maritime Consultation Organization of the United Nations. It is a problem by the regulation of marine pollution centering on (IMCO).

For this purpose, when discharging to the bottom of the ship's water (floating person under the ship) and the ship's offshore, an oil-water separation device for removing oil from the water must be prepared.

The corelet according to the present invention is most suitable for use in such marine oil separation apparatus, but of course, it can be used in an oil-water separation apparatus for removing oil contained in sewage such as factory wastewater.

Therefore, it is conventionally known to use a lipophilic and hydrophobic material as a core for granulating the fine particles of dispersed oil, and thus, such lipophilic and hydrophobic ( Or various cores made of a material having water repellency) have been proposed.

For example, the core of the oil-and-water separator disclosed in Patent Publication No. 47-20547 is made of anthracite particles or polypuroprene fibers, and the core of Patent Publication No. 48-3027 is also used. With reference to these two prior arts, in which reticular bodies such as stainless steel and polyfuroprene fibers are used, polypurpyrene fibers are the representative ones as a good hydrophobic and lipophilic material. However, the present inventors do not dare mention the polypuropyrene, but the hydrophobicity is very large. However, the hydrophilicity is too preferable in view of the characteristics of the layer thickness and the mesh. When water containing oil is passed through this polypuroprene layer, the water droplets, that is, formed and coalesced to form almost all of the granules contain water and the surface is surrounded by the oil film. In this way, the assembly made in this way has a specific gravity that does not have a balance with pure products, so it cannot be separated from the floating gravity as it is. Therefore, the oil-and-water separator of the above-mentioned conventional apparatus of Patent Publication No. 47-20547 is provided separately from the assembled water catcher oil film breaker at the rear of the colleter to destroy the skin film. In order to separate only the oil from the water droplets, and the device according to the latter Patent Publication No. 48-3027, the fine particles of the dispersed oil are kept in the core for a long time, so that the oil film is thickened and sufficient It is forbidden to have buoyancy.

In this way, the conventional corer can be formed only by the granulation of oil, which contains a little moisture, and thus has a structure in which a separate oil film breaking means is provided or the separation of the floating stress over a long time. .

Therefore, the inventors of the present invention have repeatedly studied various studies, and as a result, it is possible to take out the granulation of only oil by itself, leading to the development of a corelet that can separate floating gravity in a short time.

Such cores are filled with granular or powdery silicon pure polymer at the end of the composite downstream of the composite granulation layer, that is, the flow of water passing through the cores.

The pure polymer of this granular silicon pure polymer is a granule or powder having a diameter of 2-3 mm, which is an intermediate presence between monoma and polyma, and becomes a polymer of the previous stage leading to the polyma. Furthermore, it is classified as resin (resin).

Therefore, in one embodiment of the composite media disclosed in Japanese Patent Application Laid-Open No. 45-5715, a coating layer made of a silicon-based surface treatment agent is exemplified, but this coating layer corresponds to the state of the resin described above. It is different from the granular or powdered pure polymer according to the present invention.

This is because, in order to perform the surface treatment, the resin must be in a state of resin and granular pure polymer cannot be used.

This granular silicon pure polymer has a very large polarity, and therefore, its lipophilic and hydrophobicity are much larger than those of conventional polypuroprene fibers or Mg-containing polypuroprene fibers.

In addition, the core of the present invention is not used solely for the granular silicon pure polymer, but is formed by filling a lowermost part of the layer of a conventional granulated material and forming a part of the layer to thereby use the effect. Can exert.

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

1 shows the basic corearizer 1 of the present invention. The corerer 1 is formed in a cylindrical case 2 in order from the bottom in order to form Mg-containing polypuroprene fibers 3 as granulated material. The polypuropyrene fibers (4) and (5) were filled in a layered state and filled with granular silicon pure polymer (6) at the top, thereby forming a composite granulation layer, and at the same time, the interface of each layer was reticular. (網狀 体) It consists of partitions with (7), (8), (9), (10), and (11), and it is set as the direction from arrow X to Y of the figure of the flow direction of water containing oil. .

The lowermost Mg-containing polypropylene pyrylene fiber layer (3) has a high lipophilic property and has a catching function of trapping oil, and the polypropylene pyropyrene fiber layers (4) and (5) in the middle portion are lipophilic. Rather than hydrophobicity is good. In addition, the granular silicon porous layer 6 at the uppermost part, the lowest part of the water flow, is very lipophilic and hydrophobic, and the presence of these particles is the point of the core.

The thickness of this pure polymer layer 6 is just 10 mm or less.

The reticular bodies 7 to 11 are each made of a gold mesh of 60 mesh, but other porous materials can be used in addition to this, and a mesh of 40 to 100 mesh is suitable. .

In addition, the reticular body serves to support each layer, and also has a function of granulating dispersed oil fine particles.

Next, the operation of the corer 1 having the above configuration will be described. When water containing an oil first passes through the Mg-containing polypuroprene fiber layer 3, adsorption of oil occurs in the fiber layer 3, and when adsorption is saturated, fine particles of oil contact, adhere to, and detach from the fiber. (Iii) is repeated and axially flows in the network 8, so that the oil fine particles mutually bind and expand.

The granulated state of the oil fine particles when passing through the network 8 in the fiber layer 3 is shown in Figs. 2a and 2e. However, as is clear from this figure, the assembly A has a surface of water b as oil a. The assembly A is encapsulated and can be floated, but the specific gravity is close to water, so it is difficult to be injured in the flow.

Subsequently, when passing through the polypuroprene fiber layers 4, 5, and the reticular bodies 9, 10 in the middle portion, as shown in FIG. 3, the assembly A has a thick film of oil a. At the center it still contains water b.

In order to completely remove the moisture contained therein, the granular silicon pure polymer layer 6 at the lowermost portion is passed. When the pure polymer layer 6 passes through the reticular body 11 again, the granules containing water b are broken in the center as shown in FIG. 3 to separate the water b, and FIG. As shown in the figure, the spherical assembly A of only the oil fraction a is formed, and floating separation is extremely easy.

In this way, the oil and water are separated by passing through the core 1, so that the oil-only assembly can be formed.
