FIG. 1 illustrates a fluid separation apparatus according to one embodiment, and FIG. 2 schematically illustrates the separation of water and oil by a separation membrane in a fluid separation apparatus according to an embodiment.

The fluid separation apparatus according to one embodiment can separate a mixed fluid in which a plurality of fluids having different specific gravity are mixed into respective fluids.

For example, the plurality of fluids may comprise a first fluid and a second fluid.

Although the fluid separator according to one embodiment has been described by taking the case where two different fluids are mixed, the number of fluids mixed in the mixture is not limited thereto and may be various.

Also, the specific gravity of the first fluid may be greater than the specific gravity of the second fluid, and the first fluid may be located below the second fluid.

As such, the first fluid and the second fluid have different specific gravities, so that it is possible to form a double layer when mixed.

Hereinafter, the case where the first fluid is water and the second fluid is oil will be described as an example.

Referring to FIG. 1, a fluid separation apparatus 10 according to an embodiment may include an outer tank 100 and a water tank 110.

The external water tank 100 may be filled with water.

For example, the outer tank 100 may include a lower surface 102 and a side surface 104, and an upper surface of the outer tank 100 may have an open structure.

The lower surface 102 refers to the surface located at the lower end of the outer tank 100 and the upper surface refers to the surface located at the upper end of the outer tank 100.

Air can be freely moved into the outer tank 100 through the opened upper surface of the outer tank 100 and the pressure in the outer tank 100 can be maintained.

Although the upper surface of the outer tank 100 is opened in the figure, it is obvious that the upper surface of the outer tank 100 may be closed.

For example, in order to prevent the water in the outer tank 100 from flowing out to the outside through the upper surface of the outer tank 100 when the upper surface of the outer tank 100 is opened, May be made higher than the surface of the mixed liquid or water.

A part of the side surface 114 of the inner water tank 110 is exposed to the outside and the remaining part of the side surface 114 is exposed to the outside water tank 100, As shown in FIG.

The height difference between the surface of the water in the outer tank 100 and the surface of the water in the inner tank 110 is h1 and the height difference between the surface of the water in the outer tank 100 and the opening 112 of the inner tank 110 is h2.

By adjusting the values of h1 and h2, the amount of water or the height of the water introduced into the water tub 110 can be adjusted. This may be desirable to maintain a certain amount of water in the water bath 110 so that the oil does not contact the separation membrane SM.

For example, the ratio of h1 to h2 may be from 1:20 to 1:30.

Specifically, when h1 is 10 cm, h2 can be 200 cm to 300 cm.

The internal water tank 110 may be provided with a mixed liquid inlet pipe 116 and an oil outlet pipe 118.

The mixed liquid inlet pipe 116 may extend upward from the upper surface of the inner water tank 110. Whereby the inlet 1162 of the mixed liquid inlet pipe 116 can be disposed higher than the upper surface of the inner water tank 110.

Therefore, the water and oil mixed liquid introduced into the inlet 1162 of the mixed liquid inlet pipe 116 can be guided to the inner space of the internal water tank 110 along the mixed liquid inlet pipe 116.

In addition, the oil drain pipe 118 can be positioned at the upper side 114 of the water tank 110 so that oil can be drained from the water tank 110.

At this time, the oil outlet pipe 118 may be disposed lower than the inlet 1162 of the mixed liquid inlet pipe 116. Thereby, the outflow of the oil through the oil outlet pipe 118 from the internal water tank 110 can be induced.

As described above, the configuration in which the inlet 1162 of the mixed liquid inlet pipe 116 is disposed higher than the oil outlet pipe 118 is advantageous in that the water and the oil mixture introduced into the inlet 1162 of the mixed liquid inlet pipe 116 It is possible to provide a driving force to pass through the water tub 110. Therefore, the oil water separator 10 according to the embodiment can perform the oil water separating operation without any additional power.

Although not shown in detail, a pump (not shown) may be connected to the inlet 1162 of the mixed liquid inlet pipe 116.

The pump can supply pressure to the water and oil mixture and allow the water and oil mixture that has flowed into the inlet 1162 of the mixture inlet pipe 116 to pass through the water reservoir 110.

This pump can be usefully used when it is difficult to implement a configuration in which the pump 116 is narrow in space and the inlet 1162 of the mixed liquid inlet pipe 116 is disposed higher than the oil outlet pipe 118.

An oil collecting pipe (not shown) for collecting the oil discharged through the oil outflow pipe 118 may be disposed under the oil outflow pipe 118.

Specifically, when the oil in the water tub 110 is sufficiently cooled, the oil can flow into the oil outlet pipe 118. At this time, the oil flowing out through the oil outlet pipe 118 can be stored in the oil collecting pipe.

In addition, a separation membrane SM may be provided in the opening 112 of the water storage tank 110.

The separation membrane SM allows the opening 112 of the internal water tank 110 to communicate with the external water tank 100 and selectively separates water and oil.

At this time, the separation membrane SM may be provided in the form of a porous material including a mesh.

As the material of the separation membrane SM, various materials such as a metal, a polymer, a fiber, a ceramic, and a composite material can be used, and it is more preferable that the surface has a hydrophilic and an oleophobic surface.

Referring to FIG. 2, water can continuously pass through the separation membrane SM, but the oil can not pass through the separation membrane SM.

In addition, as described above, since the oil floats on the water due to the difference in specific gravity between the water and the water, oil is present in the upper part of the water tank 110 while water is present in the lower part. (SM) is always submerged.

This makes it possible to minimize the contamination of the separation membrane SM due to oil contact and to prevent the oil from adhering to the separation membrane SM to clog the separation membrane SM, . ≪ / RTI >

In addition, when the separation membrane SM to which the oil is adhered is exposed to the air, the oil is hardened, and in order to continue to use the separation membrane SM, the oil adhered to the separation membrane SM must be removed, The separation membrane SM in the oil water separator 10 according to the present invention may not require removal operation of the oil adhered to the separation membrane SM.

Further, the separation membrane SM may be additionally provided inside the inlet 1162 of the mixed liquid inlet pipe 116 or inside the water tank 110.

This is for filtering foreign substances contained in the mixed solution, and for example, substances other than water and oil may be removed through a separating membrane SM provided additionally.

In addition, the separation membrane SM described above may be provided in a detachable structure.

Therefore, the separation membrane SM can be removed from the opening 112 of the water tank 110, the inlet 1162 of the mixed liquid inlet pipe 116, or the inside of the water tank 110, Replacement or repair can be easily performed.

In addition, a heater (not shown) may be mounted on the fluid separation device 10 according to one embodiment.

For example, the heater may be mounted at a specific position of the inlet 1162 of the mixed fluid inlet pipe 116, the inner water tank 110, or the oil outlet pipe 118, and the fluid separation device 10 itself may be installed in the heating chamber a heating chamber (not shown).

The heater can increase the fluidity of the oil by raising the temperature of the internal water tank 110, improve the separation performance of the oil, and increase the moving speed of the oil.

In addition, the fluid separation apparatus 10 according to an embodiment may be provided with a crusher (not shown).

For example, the pulverizer may be disposed at the inlet 1162 of the mixed liquid inlet pipe 116.

The pulverizer may pulverize foreign matters in the mixture liquid or pulverize a high viscosity oil.

As a result, clogging of the separation membrane (SM), the mixed liquid inlet pipe (116) or the oil outlet pipe (118) due to suspended solids having a large particle size can be prevented and highly viscous oil can be easily separated. The separation performance of the mixed liquid can be improved.

Based on the fluid separation device 10 according to the above-described one embodiment, the fluid separation device 20 according to another embodiment and the fluid separation device 30 according to another embodiment will be described below.

FIG. 3 schematically shows a fluid separation apparatus according to another embodiment, and FIG. 4 shows a state in which a guide membrane is rotated in a fluid separation apparatus according to another embodiment.

Referring to FIG. 3, the fluid separator 20 according to another embodiment may include an outer tank 200 and a water tank 210.

The external water tank 200 and the internal water tank 210 correspond to the external water tank 100 and the internal water tank 110 of the fluid separator 10 according to the embodiment, Will be omitted.

The external water tank 200 and the internal water tank 210 may have a structure in which the upper portion is closed by the upper surfaces 202 and 212.

The upper surface 202 of the outer tank 200 may be provided with an air inlet pipe AD and the upper surface 212 of the inner tank 210 may be provided with an air inlet pipe 230.

Specifically, the air inlet pipe AD may extend upward from the upper surface 202 of the outer tank 200, and the air inlet pipe 230 may extend from the upper surface 212 of the inner tank 210 As shown in Fig.

At this time, a part of the water in the outer tank 200 may be introduced into the air inlet pipe AD, and the pressure in the outer tank 200 may be maintained. A part of the oil in the water tank 210 may be introduced into the air inlet pipe 230 and the pressure in the water tank 210 may be maintained.

Also, the inner water tank 210 may be provided with a guide film 250.

The guide film 250 may be formed in a plate shape or may extend from the upper surface 212 of the water storage tank 210 toward the opening 214.

Although a single guide film 250 is shown in the figure, it is to be understood that the guide film 250 may be provided in multiple.

The movement path of the water and oil mixed solution introduced through the mixed solution inlet pipe 220 of the inner tank 210 may be changed by the guide membrane 250 in the inner tank 210.

Specifically, the water and oil mixed liquid introduced through the inlet 222 of the mixed liquid inlet pipe 220 can be moved downward along the arrow direction A toward the opening 214.

At this time, water in the water and oil mixed solution at the end of the guide membrane 250 may be discharged into the outer tank 200 through the opening 214.

In other words, the water separated from the water and oil mixture can be mixed with the water in the outer tank 200 flowing into the inner tank 210 through the opening 214 of the inner tank 210.

Then, the oil in the water and oil mixed liquid can be moved upward from the end of the guide film 250 toward the oil outflow pipe 240 in the direction of arrow B.

As described above, the guide membrane 250 can determine the flow path of the water and oil mixed solution, and can prevent the water and the oil mixed solution flowing into the water tank 210 from flowing toward the oil outlet tube 240 directly.

Particularly, the guide membrane 250 prevents a part of the guide membrane 250 from flowing out through the oil outlet pipe 240 in a state where the water and oil mixture are not sufficiently separated in the inner water tank 210 when a large amount of water and oil mixture is introduced, can do.

In addition, the guide film 250 can be mounted rotatably in the water tub 210.

Referring to FIG. 4, the guide film 250 can rotate clockwise or counterclockwise with respect to an axis of the guide film 250 extending toward the opening 214 of the water tub 210.

One surface of the guide film 250 faces the mixed liquid inlet pipe 220 and the other surface of the guide film 250 faces the oil outlet pipe 240, 3, and the other surface of the guide film 250 may be disposed to face the rear surface.

For example, when there is a need to flow the water and the oil mixture introduced into the water tank 210 through the oil outlet pipe 240 as it is, the guide membrane 250 is rotated to change the flow path of the water and oil mixture .

Further, although not specifically shown, the guide film 250 may be provided with three compartments, for example, a first compartment, a second compartment, and a third compartment.

The first compartment and the second compartment may be connected by a line formed parallel to the direction in which the guide film 250 extends toward the opening 214 of the water tank 210. The first compartment may be connected to the second compartment It may be rotatable.

The second compartment and the third compartment may also be connected by a line formed parallel to the direction in which the guide film 250 extends toward the opening 214 of the water reservoir 210 and the third compartment is connected to the second compartment It may be rotatable.

At this time, by rotating the first compartment and the third compartment with respect to the second compartment, it is possible to change the flow path of the water and the oil mixture introduced into the water reservoir 210.

The guide membrane 250 configured as described above can efficiently separate water and oil from the water and oil mixed solution introduced into the water tank 210.

The oil separation method using the fluid separation device 20 according to another embodiment is as follows.

First, the inner water tank 210 is partially inserted into the outer water tank 200.

Water can be always present in the inner water tank 210 when the water in the outer water tank 200 flows into the inner water tank 210 and then the water and oil mixed liquid flows into the inner water tank 210, A double layer in which oil exists may be formed on the upper portion of the substrate 210. Further, the separation membrane SM provided in the opening 214 of the inner tank 210 may be continuously present in the water.

In addition, the inlet 222 of the mixed liquid inlet pipe 220 into which the water and oil mixed liquid flows may be disposed higher than the oil outlet pipe 240. Thereby, the water and oil mixed solution can naturally pass through the water tank 210.

Then, the mixture of water and oil flows into the mixed liquid inlet pipe 220.

At this time, the water and the oil mixture introduced into the inlet 222 may fill the water tank 210. For example, the water and oil mixture may flow until the water tank 210 overflows.

The water and oil mixed solution introduced into the inlet 222 may be moved downward along the guide membrane 250 toward the opening 214.

The water and oil mixed solution which reaches the end of the guide film 250 can be separated from water by the difference in specific gravity between water and oil.

Specifically, the water may be mixed with the water introduced through the opening 214 of the inner tank 210, and may be discharged to the outer tank 200 through the separation membrane SM.

On the other hand, the oil may float on the water introduced through the opening 214 of the water tank 210. At this time, impurities such as debris smaller in specific gravity than water in the water and oil mixture can also float on the water.

Then, the oil is moved upward from the end of the guide film 250 toward the oil outlet pipe 240, and then flows out through the oil outlet pipe 240.

Thus, the fluid separation apparatus according to one embodiment can efficiently separate the water and the oil mixture.
