Description

Oil-water separation device including multiple bulkhead structures overlapping {AN OIL SEPARATOR INCLUDING MULTI STORAGE TANKS WHICH ARE OVERLAPPED}

The present invention relates to an oil-water separation device, and more particularly, to an oil-water separation device in which a plurality of barrier rib structures are overlapped.

An oil-water separation device is disposed downstream of a plant or gas turbine to separate the exhaust gas and waste fuel from the plant into water and oil. Alternatively, an oil-water separator is installed in a restaurant or the like to separate water and oil from food waste mixed with water and oil.

A conventional oil-water separation device uses a separator plate method, a centrifugal separation method, or the like. The separator method is a separation method using a difference in density between water and oil, and has a structure in which a plurality of storage tanks are arranged in a row and a separator plate is disposed between the storage tanks. Water and oil are mixed and move in one direction along the separator, and during this process, oil with a low density floats to the top and water sinks to the bottom and is separated.

However, since a plurality of storage tanks are arranged long in one direction in an oil-water separation device using a conventional separator method, the volume of the storage tank increases. In particular, as the capacity of water and oil to be treated increases, the number of storage tanks increases, and the space occupied by the entire oil-water separator becomes very large.

The above-described background art is technical information that the inventor possessed for derivation of the present invention or acquired during the derivation process of the present invention, and cannot necessarily be said to be known art disclosed to the general public prior to filing the present invention.

It can be used to separate oil. In addition, the oil-water separation device 10 according to an embodiment of the present invention may be used to separate water and oil from a mixed fluid in which water and oil are mixed. Hereinafter, for convenience of description, the oil-water separation device 10 according to an embodiment of the present invention is used to separate water and oil from the first mixed fluid F1 in which exhaust gas, water, oil, and other impurities are mixed. explain about what

Referring to FIGS. 1 to 4 , the oil-water separation device 10 according to an embodiment of the present invention may include a storage tank 100 , a partition wall 200 and a cyclone separator 300 .

First, the cyclone separator 300 may separate the first mixed fluid F1 discharged from a power plant or a gas turbine when it flows into it. For example, the cyclone separator 300 is a member that separates various substances included in the first mixed fluid F1 using centrifugal force, and the first mixed fluid F1 introduced into the inside rotates along the inner surface to partially may be discharged downward as the second mixed fluid (F2), and the remaining part may be discharged upward as a gas.

In one embodiment, the cyclone separator 300 includes a body 310, a first inlet 320 for supplying the first mixed fluid F1 to the body 310, and a first discharge extending downward from the body 310. It may include a second discharge part 340 extending upward from the part 330 and the body 310 .

In one embodiment, the body 310 has a cylindrical shape, and the first mixed fluid F1 may be supplied from the outside through the first inlet 320 . The first discharge unit 330 may have a truncated cone-shaped portion 331 and a cylindrical portion 332 extending downward from the truncated cone-shaped portion 331 . Also, the second discharge unit 340 may have a cylindrical shape elongated upward from the body 310 .

The cyclone separator 300 discharges the second mixed fluid F2 containing water W and oil O from the first mixed fluid F1 downward through the first discharge unit 330, and the rest It may be discharged upward through the second discharge unit 340 in a gaseous state.

In one embodiment, the second mixed fluid F2 discharged through the first discharge unit 330 may include unavoidable impurities in addition to water W and oil O.

The second mixed fluid F2 discharged from the cyclone separator 300 is introduced into the storage tank 100 . For example, the storage tank 100 may be disposed below the cyclone separator 300, that is, below the first discharge unit 330. In one embodiment, the storage tank 100 may be disposed coaxially with the central axis Ax of the oil/water separation device 10 .

In one embodiment, the storage tank 100 stores the second inlet 110 into which the second mixed fluid F2 flows from the first outlet 330 and the water W separated from the second mixed fluid F2. It may include a water discharge unit 120 for discharging and an oil discharge unit 130 for discharging the oil O separated from the second mixed fluid F2.

In one embodiment, the second inlet 110 is connected to the first outlet 330 and may be a through hole formed on the upper surface of the storage tank 100 . The second mixed fluid F2 introduced into the second inlet 110 moves into the inner space 140 of the reservoir 100 .

The water discharge unit 120 is disposed on one side of the storage tank 100 to discharge water separated from the second mixed fluid F2 to the outside. For example, the water discharge unit 120 may be disposed on the lower surface of the storage tank 100 . That is, in the second mixed fluid F2 introduced into the storage tank 100, the high-density water (W) moves downward and the low-density oil (O) moves upward. ), it is possible to discharge water (W) to the outside. This will be described later.

The oil discharge unit 130 is disposed on the other side of the storage tank 100 to discharge oil separated from the second mixed fluid F2 to the outside. For example, the oil discharge unit 130 may be disposed on the side or upper surface of the storage tank 100 to discharge the oil O located at a relatively higher level than the water W to the outside. This will be described later.

The partition 200 is disposed inside the storage tank 100 to separate water (W) and oil (O) from the second mixed fluid (F2). For example, a plurality of partition walls 200 may be disposed spaced apart from each other in the internal space 140 of the storage tank 100 .

In one embodiment, when viewed from the top, the barrier rib 200 forms a closed loop and may partition regions having different areas.

In one embodiment, the bulkhead 200 is included in the inner space 140 of the storage tank 100, and may have a circular or polygonal shape without a broken part when viewed from the top. In addition, the outermost partition wall 200 among the plurality of partition walls 200 may be disposed to include all other partition walls 200 therein. That is, the size of the partition wall 200 may gradually increase toward the outside from the center of the storage tank 100 .

In one embodiment, the partition wall 200 with the smallest size may be disposed at the center of the storage tank 100, and the remaining partition walls 200 may be disposed such that the partition wall 200 with the smallest size is included therein. Also, among the plurality of barrier ribs 200 , the larger barrier rib 200 may be arranged to include the other barrier ribs 200 smaller than the barrier rib 200 .

For example, as shown in FIGS. 2 to 4 , the plurality of barrier ribs 200 may have a cylindrical shape having different diameters. Also, among the plurality of barrier ribs 200 , the barrier rib 200 having a large diameter may be arranged to include the barrier rib 200 having a small diameter.

The number of partition walls 200 is not particularly limited, and may be appropriately selected in consideration of the flow rate and capacity of the first mixed fluid F1 or the second mixed fluid F2 to be treated. Hereinafter, for convenience of description, a case in which the number of partition walls 200 is four will be mainly described.

For example, the partition 200 may include a first partition 210 , a second partition 220 , a third partition 230 and a fourth partition 240 .

The first partition wall 210 may be disposed on one side of the storage tank 100 . For example, the first partition wall 210 may be arranged so that the center of the storage tank 100 is included therein.

In one embodiment, the first partition wall 210 may extend downward from the upper surface of the storage tank 100 by a first height H1. That is, as shown in FIG. 2 , one end of the first partition wall 210 is connected to the top surface of the storage tank 100 and the other end is spaced apart from the bottom surface of the storage tank 100 by a first distance C1.

The second barrier rib 220 may be spaced apart from the outer circumferential surface of the first barrier rib 210 so that the first barrier rib 210 is included therein.

In one embodiment, the second partition wall 220 may extend upward from the bottom surface of the storage tank 100 by a second height H2 . That is, as shown in FIG. 2 , one end of the second partition wall 220 is connected to the bottom surface of the storage tank 100 and the other end is spaced apart from the top surface of the storage tank 100 by a second distance C2.

The third barrier rib 230 may be spaced apart from the outer circumferential surface of the second barrier rib 220 so that the second barrier rib 220 is included therein. That is, both the first partition 210 and the second partition 220 may be disposed inside the third partition 230 .

In one embodiment, the third partition wall 230 may extend downward from the upper surface of the storage tank 100 by a third height H3. That is, as shown in FIG. 2 , one end of the third partition wall 230 may be connected to the top surface of the storage tank 100 and the other end may be spaced apart from the bottom surface of the storage tank 100 by a third distance C3.

In an embodiment, the third height H3 of the third partition wall 230 may be different from the first height H1 of the first partition wall 210 . For example, the first height (H1) is lower than the third height (H3), through which a larger amount of the second mixed fluid (F2), more specifically, a larger amount of water (W) (or oil ( Water (W) mixed with a part of O) may quickly pass through the first barrier rib 210 . In addition, by disposing the third partition wall 230 closer to the bottom surface of the storage tank 100, water W and oil O can be more accurately separated.

The fourth barrier rib 240 may be spaced apart from the outer circumferential surface of the third barrier rib 230 so that the third barrier rib 230 is included therein. That is, the first partition 210 , the second partition 220 , and the third partition 230 may all be disposed inside the fourth partition 240 .

In one embodiment, the fourth partition wall 240 may extend upward from the bottom surface of the storage tank 100 by a fourth height H4. That is, as shown in FIG. 2 , one end of the fourth partition wall 240 may be connected to the bottom surface of the storage tank 100 and the other end may be spaced apart from the top surface of the storage tank 100 by a fourth distance C4.

In one embodiment, the fourth height H4 of the fourth partition wall 240 may be different from the second height H2 of the second partition wall 220 . For example, the fourth height H4 may be set lower than the second height H2 in consideration of the fact that the flow rate decreases from the center of the storage tank 100 to the outside.

In one embodiment, the plurality of barrier ribs 200 may be disposed concentrically with each other. For example, as shown in FIGS. 2 to 4 , the first partition 210 , the second partition 220 , the third partition 230 and the fourth partition 240 may be disposed concentrically with each other.

In one embodiment, separation distances between the plurality of barrier ribs 200 may be different from each other. For example, the separation distance between the partition walls 200 may decrease as the distance from the center of the storage tank 100 increases. Accordingly, the water (W) between the partition walls 200 is maintained at a sufficient level so that the water (W) can easily move through the first discharge channel 221 and the second discharge channel 241 described later.

In one embodiment, the plurality of barrier ribs 200 may include pipes for moving the water W to the next barrier rib 200 . For example, the second partition wall 220 may have a first discharge channel 221 on one side and the fourth partition wall 240 may have a second discharge channel 241 on one side.

The second discharge channel 221 is a pipe or pipe inserted through the second partition wall 220 in the thickness direction, and may be spaced apart from the bottom surface of the storage tank 100 by a predetermined height. Accordingly, when the water W introduced into the second partition wall 220 exceeds a predetermined water level, it is discharged to the outside of the second partition wall 220 through the second discharge channel 221 .

The fourth discharge channel 241 is a pipe or pipe inserted through the fourth partition wall 240 in the thickness direction and may be spaced apart from the bottom surface of the storage tank 100 by a predetermined height. In one embodiment, the height of the fourth discharge channel 241 may be lower than the height of the second discharge channel 221 . Accordingly, when the water W introduced into the fourth partition wall 240 exceeds a predetermined water level, it is discharged to the outside of the fourth partition wall 240 through the fourth discharge channel 241 .

The heights of the second discharge channel 221 and the fourth discharge channel 241 are not particularly limited. However, since the relatively low-density oil (O) is located at the top of the bulkhead 200, the oil (O) may be spaced downward from the upper end of the bulkhead 200 by a predetermined height so that the oil (O) does not leak to the outside. there is.

In another embodiment, a pump (not shown) may be disposed on the partition wall 200 to move the water (W) using external power.

In one embodiment, the storage tank 100 may include an oil-water separation region partitioned by a plurality of partition walls 200 .

For example, the storage tank 100 may include a first oil-water separation region SP1 partitioned into an inner space of the first partition wall 210 . As shown in FIGS. 2 and 3 , the first oil-water separation region SP1 may be partitioned by the inner circumferential surface of the first partition wall 210 . The lower part of the first oil-water separation region SP1 may be connected to the second oil-water separation region SP2 by the first partition wall 210 spaced apart from the bottom surface of the storage tank 100 . That is, the first oil-water separation region SP1 may have a circular shape when viewed from the top. In one embodiment, the first oil-water separation region SP1 may be disposed coaxially with the central axis Ax of the oil-water separation device 10 or the storage tank 100 .

When the second mixed fluid F2 flows into the storage tank 100, impurities IP included in the second mixed fluid F2 and having a high density are accumulated on the bottom surface of the first oil-water separation region SP1. And water (W) and oil (O) may form a layer on top of it.

The second oil-water separation region SP2 may be partitioned by an inner circumferential surface of the second partition 220 and an outer circumferential surface of the first partition 210 . That is, the second oil-water separation region SP2 may have a ring shape when viewed from the top.

The second oil-water separation region SP2 is connected to the first oil-water separation region SP1. The water W may move to the second oil-water separation region SP2 while passing through the lower end of the first partition wall 210 . Here, some of the oil (O) may move together, and the water (W) and the oil (O) may be separated again by a difference in density in the second oil-water separation region (SP2).

The third oil-water separation region SP3 may be partitioned by an outer circumferential surface of the second partition 220 and an inner circumferential surface of the third partition 230 . That is, the third oil-water separation region SP3 may have a ring shape when viewed from the top.

The third oil-water separation region SP3 may be connected through the first discharge channel 221 provided in the second partition wall 220 . When the water W introduced into the second oil-water separation region SP2 exceeds the height at which the first discharge channel 221 is disposed, the water W passes through the first discharge channel 221 to the third oil-water separation region ( SP3) can flow into it. Here, some of the oil (O) may move together, and the water (W) and the oil (O) may be separated again by a difference in density in the third oil-water separation region (SP3).

The fourth oil-water separation region SP4 may be partitioned by an inner circumferential surface of the fourth partition 240 and an outer circumferential surface of the third partition 230 . The lower part of the fourth oil-water separation region SP4 may be connected to the third oil-water separation region SP3 by the third partition wall 230 spaced apart from the bottom surface of the storage tank 100 . That is, the fourth oil-water separation region SP4 may have a ring shape when viewed from the top.

The water W may move to the fourth oil-water separation region SP4 while passing through the lower end of the third partition wall 230 . Here, some of the oil (O) may move together, and the water (W) and the oil (O) may be separated again by a difference in density in the fourth oil-water separation region (SP4).

The fifth oil-water separation region SP5 may be partitioned by the outer circumferential surface of the fourth partition wall 240 and the inner circumferential surface of the storage tank 100 . That is, the fifth oil-water separation region SP5 may have a ring shape when viewed from the top.

The fifth oil-water separation region SP5 may be connected through the second discharge channel 241 provided in the fourth partition wall 240 . When the water W introduced into the fourth oil-water separation region SP4 exceeds the height at which the second discharge channel 241 is disposed, the water W passes through the second discharge channel 241 to the fifth oil-water separation region ( SP5). Here, water (W) and oil (O) can be completely separated while passing through the first partition wall (210) to the fourth partition wall (240), and only water (W) can be introduced into the fifth oil-water separation region (SP5). there is.

In one embodiment, the water discharge unit 120 may be disposed to correspond to the oil-water separation area. For example, as shown in FIG. 3 , the water discharge unit 120 may be disposed on the lower surface of the storage tank 100 to discharge the separated water W to the outside. In one embodiment, the water discharge unit 120 may not be disposed in the first oil-water separation region SP1 and the second oil-water separation region SP2 so that impurities IP do not flow in.

In one embodiment, the water discharge unit 120 may include a first water discharge pipe 121 , a second water discharge pipe 122 and a third water discharge pipe 123 .

The first water discharge pipe 121 is connected to the third oil and water separation region SP3, the second water discharge pipe 122 is connected to the fourth oil and water separation region SP4, and the third water discharge pipe 123 may be connected to the fifth oil-water separation region SP5.

In one embodiment, each water discharge pipe is provided with a valve (reference numeral not shown), and by opening and closing the valve through external control, it is possible to adjust whether or not the water (W) is discharged and the flow rate.

In one embodiment, an impurity discharge unit 150 may be disposed on one side of the storage tank 100 . For example, as shown in FIG. 3 , the impurity discharge unit 150 may be disposed on the lower surface of the storage tank 100 to be connected to the first oil-water separation region SP1. The impurity discharge unit 150 may discharge impurities IP accumulated in the first oil/water separation region SP1 to the outside.

In one embodiment, the oil discharge unit 130 may include an oil discharge pipe 131 . 3 shows that the oil discharge pipe 131 has a valve and is disposed on the upper surface of the storage tank 100, but is not limited thereto. For example, the oil discharge unit 130 may be disposed on the side of the storage tank 100 as shown in FIG. 2 .

Alternatively, a plurality of oil discharge units 130 or oil discharge pipes 131 may be disposed on the upper surface of the storage tank 100 so as to be connected to the upper portions of each oil-water separation region.

Through such a configuration, the oil-water separation device 10 according to an embodiment of the present invention includes a multi-partition structure overlapping, thereby reducing the overall size of the device and significantly improving the oil-water separation treatment capacity.

More specifically, as shown in FIG. 5, as a comparative example, the conventional oil-water separator 10' has a structure in which a plurality of partition walls 200' having a plate shape are spaced apart from each other and disposed in one direction. Therefore, the mixed fluid flowing into the oil-water separation device 10' moves in only one direction, and since the oil-water separation is also performed in only one direction, a large amount of mixed fluid cannot be processed at the same time.

In particular, in order to improve the oil-water separation capacity and precision, the overall size of the reservoir must be increased and a greater number of partition walls 200' must be disposed, so that the partition walls 200' are very long in the direction in which they are arranged.

On the other hand, the oil-water separation device 10 according to an embodiment of the present invention can process a large amount of mixed fluid at the same time because the plurality of barrier ribs 200 are arranged to overlap each other. That is, as shown in FIG. 6A, when the distance C and the diameter of the partition wall 200 from the bottom surface of the storage tank 100 is D, the fluid that can move through the gap between the storage tank 100 and the partition wall 200 The flow rate is:

On the other hand, as shown in FIG. 6B, even if it is assumed that the fluid moves at the same flow rate in the comparative example and the width of the partition wall 200' is the same as the diameter D of the partition wall 200 according to the invention, the storage tank and the partition wall 200' ), the flow rate of the fluid that can move through the gap between

That is, even when the first partition wall (the first partition wall 210 in the case of the invention example) disposed in the storage tank has the same width or diameter, the flow rate of the fluid that can move through the clearance between the storage tank and the partition wall in the invention example compared to the comparative example It can be seen that is larger by π times. This difference is equally applied to the additionally disposed bulkhead.

Therefore, the oil-water separation device 10 according to an embodiment of the present invention can process a larger amount of mixed fluid than the conventional oil-water separation device 10' and at the same time reduce the overall size of the device.

As such, the present invention has been described with reference to the embodiments shown in the drawings, but this is only an example. Those skilled in the art can fully understand that various modifications and equivalent other embodiments are possible from the embodiments. Therefore, the true technical protection scope of the present invention should be determined based on the appended claims.
