Description

Oil mist separator for ships

The present invention relates to an oil vapor separation device for a ship.

Generally, an internal combustion engine such as a diesel engine is generally used as a marine engine. Lubricant oil for lubrication is supplied to the internal combustion engine through a narrow flow path.

The lubricating oil supplied to the internal combustion engine through the narrow flow path is heated by friction energy and thermal energy of the engine explosive force. Due to this, the temperature of the internal combustion engine is increased, and evaporation is promoted to generate oil mist inside the engine.

These vapors accumulate inside the engine block of a diesel engine, which can lead to dangerous situations. That is, when oil vapor is accumulated inside the engine block, the engine block may explode as gas and sparks generated during engine operation become potential as the vapor accumulated in the engine block.

In order to prevent this, a technique for discharging oil vapor generated from a diesel engine to the outside has been proposed.

However, when the oil vapor is discharged directly to the outside, the oil vapor condenses rapidly due to a temperature difference while contacting the outside air, and the condensed water and oil drop by its own weight, and the hull around the piping path and the piping path, for example, the upper surface of the deck As it adheres to the back, there is a risk of a safety accident.

In order to solve this problem, a technique capable of filtering off the oily gas generated inside the engine of the ship before discharging it to the outside is disclosed in <Patent Documents 1> to <Patent Documents 2>.

The prior art disclosed in <Patent Document 1> is installed in communication with the pipe line of the oil vapor discharged from the fuel tank provided in the hull, and the condensation container for recovering moisture or oil formed by condensation of the oil vapor discharged from the pipe line and It is installed in communication with the lower end of the condensing container and is provided with a configuration including a discharge part for discharging the water or oil recovered to the condensing container to the outside of the fuel tank, so that the water and oil formed by condensing oil vapor are collected separately and bilge. By collecting in the tank, water and oil can be reduced from falling to the upper end or hull of the pipeline, thereby reducing corrosion of the pipeline and reducing contamination of the hull.

In the prior art disclosed in <Patent Document 2>, an inlet port connected to an oil vapor discharge pipe of a ship is formed on one side, and a first exhaust mechanism communicating with the outside is formed on the other side, and a case having an oil vapor path formed therein, and the oil vapor passage A separator installed at a predetermined interval inside the case so as to communicate in a zigzag manner, a discharge means provided on one side of the case and condensed inside the case to discharge collected engine oil to the outside, and the first exhaust port of the case A first exhaust pipe which is connected and installed so that the end portion thereof is curved downward, a second exhaust pipe formed in the case, and is connected to and installed in the second exhaust pipe, and the upper end thereof enters into the inside of the end portion of the first exhaust pipe and exhaust path therebetween. By providing a configuration including a second exhaust pipe to be formed, it is possible to reduce the effort required for ship maintenance by preventing the hull from being polluted by oil discharged through the steam discharge pipe.

However, the prior art disclosed in <Patent Documents 1> to <Patent Documents 2> has the disadvantage that the high-temperature and high-pressure steam is not sufficiently condensed inside, and the steam containing some oil is discharged to the outside. For this reason, the risk of safety accidents and the pollution of ships and marines are still occurring.

The present invention has been proposed to solve various problems occurring in the prior art as described above, by sufficiently separating the oil content of the oil vapor generated in the diesel engine of the ship, to prevent the discharge of some oil vapor is not separated from the outside It is to provide an oil vapor separation device for a ship.

In order to achieve the above-described problems, the oil vapor separation device for a ship according to the present invention includes an inlet pipe, a case, an outlet pipe, and a drain pipe. The inflow pipe introduces steam from the ship's internal combustion engine. In the case, the inlet pipe is inserted into the lower side, and the oil component of the vapor introduced through the inlet pipe is first separated. The discharge pipe is installed in communication with the upper portion of the case, and the residual oil of the primary vapor separated from the case is secondarily separated to discharge only the air from which the oil has been removed to the outside.

In order to fully understand the present invention and the operational advantages of the present invention and the objects achieved by the practice of the present invention, reference should be made to the accompanying drawings and the contents described in the accompanying drawings, which illustrate exemplary embodiments of the present invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, and in describing with reference to the accompanying drawings, identical or corresponding components will be given the same reference numbers and redundant description thereof will be omitted. do.

1 is a cross-sectional view of an oil vapor separation device for a ship according to a preferred embodiment of the present invention.

Referring to FIG. 1, the steam separation device 100 for a ship according to a preferred embodiment of the present invention includes an inlet pipe 110, a case 120, an outlet pipe 130 and a drain pipe 140.

The inflow pipe 110 serves to guide oil vapor from the internal combustion engine (not shown) of the ship and guide the introduced oil vapor to the case 120.

To this end, the inlet pipe 110 is formed of a general pipe-shaped pipeline, and is preferably made of a material such as stainless steel or carbon nanotubes to withstand high-pressure steam. In addition, it is preferable that the inlet pipe 110 has a predetermined thickness to withstand high-pressure steam.

The inlet pipe 110 is connected to an oil vapor discharge pipe (not shown) in which one end discharges the vapor generated from the ship's internal combustion engine (not shown), and the other end is inserted into the lower side of the case 120. .

On the other hand, the inlet pipe 110, it is preferable that the portion connected to the case 120 is sealed with a sealing member in order to prevent leakage of oil or oil formed separately from the vapor introduced into the case 120.

At this time, the inlet pipe 110 inserted into the lower side of the case 120 is disposed to face vertically at a position close to the inner wall of the case 120, as shown in Figure 1, the top of the case 120 And a certain interval.

Due to this, it is possible to prevent the vapor flowing into the inlet pipe 110 is directly discharged to the outside through the outlet pipe 130. In addition, it is possible to lower the pressure of the oil vapor by causing the oil vapor flowing into the inlet pipe 110 to hit the inner wall of the case 120, thereby generating a primary condensation effect.

On the other hand, although not shown in the drawing, a valve for controlling the inflow of oil vapor flowing into the case 120 may be provided on one side of the inlet 110.

Referring to FIG. 1, the case 120 may be formed in a box shape, and a predetermined internal space S is formed therein. In this case 120, the inlet pipe 110 is inserted into the lower side, and serves to primarily separate the oil of the vapor introduced through the inserted inlet pipe 110.

Meanwhile, the case 120 is illustrated in a box shape in the drawing, but this is only an example for description, and may be formed in various shapes such as a column shape.

Since the case 120 is cooled by outside air, the interior space S maintains a relatively low temperature compared to the vapor.

Due to this, the oil vapor introduced into the inner space S of the case 120 hits the inner wall surface of the case 120, and the pressure is lowered, and is cooled while being in contact with the inner wall surface of the case 120 to be liquid oil. Condensation.

The oil formed on the inner wall surface of the case 120 moves downward along the inner wall surface by its own weight and accumulates on the inner bottom of the case 120.

At this time, if the oil formed on the inner wall surface of the case 120 accumulates on the inner bottom of the case 120, the air flow inside the case 120 may be prevented or the oil may be included in the air again. ), A drain pipe 140 for discharging oil may be installed in communication with the other lower side.

Here, the drain pipe 140 is a pipe for discharging the collected oil as it is separated from the case 120 and the discharge pipe 130 to be described later, and may be formed of a general pipe-shaped pipe.

At this time, although not shown in the drawing, the oil discharged to the drain pipe 140 may be collected by being moved to a bilge tank provided at an end of the drain pipe 140. Here, the bilge tank refers to a reservoir for collecting water, oil, and waste oil generated from a ship and separating and recycling water and oil, respectively.

Meanwhile, although not shown in the drawing, a valve for controlling the inflow of oil flowing from the case 120 may be provided on one side of the drain pipe 140.

In addition, although not shown in the drawing, the bottom surface of the case 120 is inclined at a predetermined angle in the direction in which the drain pipe 140 is provided so that the oil accumulated in the inner bottom can smoothly move to the drain pipe 140. Can be configured.

Referring to FIG. 1, the discharge pipe 130 is formed in a general pipe shape, like the inlet pipe 110, and may be made of a material such as stainless steel or carbon nanotubes to withstand high-pressure steam. In addition, the discharge pipe 130, like the hydraulic pipe 110, it is preferable to have a predetermined thickness that can withstand high-pressure steam.

The discharge pipe 130 is installed in communication with the upper portion of the case 120, and serves to discharge the residual oil of the primary vapor separated from the case 120 by secondary separation to discharge only the air from which the oil is removed to the outside.

To this end, the discharge pipe 130 is provided with a corrugated plate 131 therein.

At this time, the corrugated plate 131 will be described in detail with reference to other drawings.

Meanwhile, the discharge pipe 130 is preferably formed to have a larger diameter than the inlet pipe 110.

For this reason, as the inlet pipe 110 is disposed to face vertically at a position close to the inner wall of the case 120 and the upper end is spaced apart from the upper part of the case 120 at a predetermined interval, pressure is applied toward the wall, so that the vapor pipe is discharged 130 ) To prevent smooth discharge.

FIG. 2 is a view showing the corrugated plate shown in FIG. 1.

The corrugated plate 131 will be described in detail with reference to FIGS. 1 and 2.

1 and 2, the corrugated plate 131 is for additionally filtering residual oil contained in the vapor that is discharged to the outside, and is formed of a corrugated plate having a corrugated shape with acids and valleys, and the discharge pipe 130 It is inclined at regular intervals on the inner wall, but alternately installed.

In addition, the corrugated plate 131 is formed with a plurality of through holes (131a) in the mountains and valleys, respectively.

Accordingly, the corrugated plate 131 serves to disperse the flow of the vapor flowing from the inlet pipe 110 to the outlet pipe 130, and also serves to separate the oil contained in the vapor.

In addition, it is possible to efficiently condense the vapor by placing the corrugated plate 131 in multiple stages inside the discharge pipe 130.

On the other hand, although not shown in the drawing, a plurality of through holes (131a) formed in the mountains and valleys of the corrugated plate 131 in order to effectively separate the oil contained in the vapor can be configured in various sizes.

For example, the plurality of through holes 131a formed in the mountains and valleys of the corrugated plate 131 may be formed to gradually decrease in diameter or increase in diameter from one side to the other side, that is, the A direction or the B direction along the flow direction of the vapor.

As such, the corrugated plate 131 may be corrugated in the A direction or the B direction, as shown in FIGS. 2A and 2B.

As shown in FIG. 2A, when the corrugated plate 131 is corrugated in the A direction, the gas passing rate of the vapor becomes lower, so that the cohesive force is improved, and oil can be effectively collected.

Unlike this, as shown in FIG. 2B, when the corrugated plate 131 is corrugated in the B direction, the gas passing rate of the vapor increases, so that the recovery rate can be increased.

The corrugated plate 131 having such a configuration may be variously applied inside the discharge pipe 130 according to the speed and pressure of the vapor.

Therefore, as the corrugated plate 131 is provided inside the discharge pipe 130, condensation of the oil vapor is actively performed, and oil collection by condensation can be more effectively performed.

3 shows that the corrugated plate shown in FIG. 1 separates vapor.

At this time, in describing FIG. 3, a detailed description of the same parts as in FIGS. 1 and 2 or parts that can be easily understood with reference to FIGS. 1 and 2 will be omitted.

The corrugated plate 131 is spaced at a predetermined interval on the inner wall of the discharge pipe 130, but is alternately installed. The plurality of through holes 131a formed in the corrugated plate 131 is firstly separated from the case 120 to pass through the oil vapor M1 containing a small amount of residual oil before being discharged to the outside.

If the oil vapor passes through a plurality of through holes 131a formed in the corrugated plate 131 before being discharged to the outside, the oil is condensed in the lower portion of the corrugated plate 131 to form an oil.

The oil formed at the bottom of the corrugated plate 131 is collected while flowing down the slope, and the collected oil falls to the bottom surface of the case 120 by its own weight.

Then, the oil vapor (M2) from which the oil is separated is discharged upward through a plurality of through holes (131a) only gas remains.

On the other hand, as shown in Figure 3, the corrugated plate 131 may be formed with a low density of acid and bone so that the area in contact with the vapor is large.

Accordingly, a lot of oil is formed on the lower portion of the corrugated plate 131, and it can be quickly collected.

The oil separated from the corrugated plate 131 and dropped to the bottom surface of the case 120 is discharged to the drain pipe 140 described above.

Accordingly, the ship's oil vapor separation device 100 according to the present invention can sufficiently separate the oil vapor contained in the oil vapor through the corrugated plate 131, to prevent some oil vapor that is not separated oil is discharged to the outside, Deck floors and the environment can be prevented from being contaminated.

Although the invention made by the present inventors has been described in detail according to the above-described embodiments, the present invention is not limited to the above-described embodiments, and it is needless to say that various modifications can be made without departing from the gist thereof.
