Document 1 KR 10-1982-0002247 B1 1982.12.08

In general, the fuel of diesel engines mounted on small and medium-sized vessels uses diesel fuel having good combustibility, but it is required to use cheaper fuel oil for the economics of the vessel operation due to soaring oil prices.

However, heavy oils (banka A oil and C oil), which can be used as fuels for ship diesel engines, use alumina and silica as catalysts in the production of heavy oils, so the fine particles remain as sludge. Particulate impurities, such as alumina and silica, are very hard and cause wear on piston rings and fuel pumps of diesel engines.

In addition, since heavy oil contains vanadium, it is known to erode a metal material by making a low melting point compound at the time of combustion, thereby causing damage by vanadium penetration into a combustion chamber, a supercharger, and an exhaust system of a diesel engine.

 In addition, since heavy oil contains a lot of impurities such as moisture and sulfur, combustion efficiency is lowered, which causes incomplete combustion, as well as clogging of the fuel filter and sticking phenomenon in the nozzle, causing engine failure.

Therefore, heavy oil cannot be used as it is a lower fuel oil as a diesel engine fuel oil.

Therefore, in order to use heavy oil as fuel for marine diesel engines, it is necessary to use impurities as fuel after removing impurities contained in heavy oil. As a prior art, an apparatus for reforming fuel oil using ultrasonic waves disclosed in Korean Patent Publication No. 10-1982-0002247 There is.

The prior art is able to emulsify impurities using ultrasonic waves, but because the fuel oil is emulsified by ultrasonic waves as the mesh rotates in one device, the impurities filtered in the mesh continue to accumulate, and thus the fuel inside the mesh. Oil is not properly affected by ultrasonic waves, resulting in low efficiency of emulsification.

In addition, since it operates while accommodating impurities accumulated outside the mesh as it is, when accumulated for a long time or a long time operation may be caused by the accumulated impurities.

In particular, heavy oils are low-grade fuel oils due to the high impurity content, but when used as a device for reforming such heavy oils, the probability of failure is greater.

When the ship departs, it stays at sea for a long time or a long time. If a failure occurs while the prior art device is installed and the fuel oil of the diesel engine is used as heavy oil, the ship may cause a safety accident that can only drift. The fuel oil reformer of the technology is very unsuitable as a device for reforming heavy oil used as fuel oil for marine diesel engines.

Therefore, the applicant has developed a device for allowing heavy oil to be used as a diesel engine fuel oil while being installed on a vessel and has been filed and filed as a Korean Patent Application No. 10-2006-0103313.

However, the above-described application technology can emulsify heavy oil by ultrasonic waves, but its limitation is limited. Therefore, it has been found that the combustion efficiency increases only when impurities are removed before emulsifying heavy oil by ultrasonic waves.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing the overall device for the heavy fuel reforming process according to the present invention, the ship has a main fuel tank (1) and the fuel is supplied from the main fuel tank (1) diesel engine (2) ) And the present invention is installed between the main fuel tank (1) and the diesel engine (2).

Therefore, the present invention includes a service fuel tank 10 in which heavy oil s stored in the main fuel tank 1 is transferred by the transfer pump 3 to temporarily store heavy oil. 10) The heavy oil stored therein is to be heated by the electric heater (11).

As heavy oil has a high pour point, as it is known, fuel may not flow when the outside air temperature is below 2.5 ° C in winter. Therefore, by heating the heavy oil (s) in the service fuel tank (10) in the winter by the electric heater (11) to allow the heavy oil to flow into the pipe.

The heavy oil s of the service fuel tank 10 is supplied to the alternating filtration means 20 through the manual valve 4 and the heavy oil passing through the alternating filtration means 20 passes through the pump combined grinding means 30. It is.

Therefore, the heavy oil (s) of the service fuel tank (10) flows through the pipe because the pump acts to pump the heavy oil (s) through the pipe in the combined grinding means (30).

On the other hand, since the valves such as the manual valve 4 in the system diagram of Fig. 1 are known conventional valves, other manual valves other than the manual valve 4 installed for the first time from the service fuel tank 10 are omitted at the same time. The description is also omitted. In addition, the reference numerals of the pipes connected to the respective devices will be omitted and described.

2 and 3 show the alternate filtration means 20 according to the present invention, wherein the alternate filtration means 20 is largely divided into a pair of filter parts 26, 26 ′ and one on the body 21. It is divided into the switching control unit 29.

Referring to FIG. 2, the body 21 includes an inlet 21a and an outlet 21b on one side and an underside thereof, and a valve hole 27 for constituting the switching operation unit 29.

The valve hole 27 is provided with a rotation valve shaft 28 having a supply hole 28a and an outlet hole 28b, and the rotation valve shaft 28 is installed to be rotatable by a lever 28c.

Accordingly, when the lever 28c is rotated in the left or right direction, the rotation valve shaft 28 is rotated in the left or right direction, so that the heavy oil s is a pair of filter portions 26, 26 'as shown in FIG. The heavy oil (s) is supplied only to one filter unit 26 or 26 'selected from) to filter foreign matters.

That is, as shown in the solid line in FIG. 3, the supply hole 28a and the outlet hole 28b of the rotary valve shaft 28 coincide with the supply hole 22a and the outlet hole 22b of one filter hole 22. Heavy oil (s) is introduced into and out of one filter portion (26), and the rotary valve shaft (28) is rotated by the operation of the lever (28c) so that the supply hole (28a) and the outlet hole (28b) of the other When the fuel hole 22a and the outlet hole 22b of the filter hole 22 coincide with each other, the heavy oil s enters and exits the other filter portion 26 '. Alternately to feed heavy oil (s) to be filtered.

As described above, the heavy oil s is supplied to only one filter unit 26 or 26 'so that the filter unit 26 is cleaned while the other filter unit 26' is filtered. will be.

Therefore, as shown in FIGS. 2 and 3, the pair of filter parts 26 and 26 ′ has heavy oil s entering and exiting through respective supply holes 22a and outlet holes 22b formed in the body 21. Each of the filter holes 22 is provided.

The filter hole 22 includes a primary metal filter cylinder member 23 and a secondary metal filter cylinder member 23 ', and an upper portion of the first and second metal filter cylinder members 23 and 23'. The lid 25 is to be covered.

The upper cover 25 is pressurized by the pressing bolt member 24b fastened to the nut portion 24c of the locking member 24 to which the locking end portion 24a is locked to the locking jaw portion 21c of the body 21. It is.

That is, when the pressure bolt member 24b is rotated in the right direction, the upper cover 25 is pressurized as it is gradually lowered. On the contrary, when the pressure bolt member 24b is rotated in the left direction, the pressure bolt member 24b is moved upward. As it rises, the upper cover 25 and the locking member 24 are released to be separated.

Therefore, by opening the filter hole 22, the primary and secondary metal filter cylinder members 23 and 23 'can be drawn out from the filter hole 22, and thus the primary and secondary metal filter cylinder members 23, 23 ') and the inside of the filter hole 22 can be cleaned.

Meanwhile, in the filter parts 26 and 26 ', the heavy oil s introduced through the supply holes 22a passes through the primary metal filter cylinder member 23, and then passes through the secondary metal filter cylinder member 23'. It is discharged to the exit hole 22b. The primary and secondary metal filter cylinder members 23 and 23 'are used having a hole of 300-350 mesh.

Therefore, the foreign matter contained in the heavy oil (s) is caught and remains in the filter parts 26 and 26 ', and the filtered foreign matter is cleaned and removed later, while one filter part 26' is being cleaned. Since the filter unit 26 can be operated, the system of the present invention can be operated without stopping.

Therefore, the heavy oil s from which foreign matter is removed by the alternate filtering means 20 is transferred to the combined pump means 30.

Referring to (a) and (b) of FIG. 4, the pump-pulverizing means 30 includes a pair of circulation holes 32 and 32 'in the body 31, and the pair of circulation holes 32, 32 '), a pair of gear rotating bodies 33 and 33' are respectively meshed with each other so as to be rotatable.

In addition, only one of the gear rotating bodies 33 of the pair of gear rotating bodies 33 and 33 'is connected to the drive shaft 34a of the motor 34 so as to be rotated. The motor 34 rotates at high speed at a speed of 1500 rpm / min.

In addition, heavy oil s is introduced into the inlet 32a of any one of the pair of circulation holes 32 and 32 'and the outlet 32b of the circulation hole 32 is primarily introduced. It is configured to be connected to the inlet 32c and the connection pipe 35 of the other circulation hole (32 ') through the heavy oil (s) is introduced into the outlet 32d after the secondary.

Therefore, the heavy oil (s) first introduced into the circulation hole 32 is passed through the gear teeth (not shown) to mesh with each other because the pair of gear rotating body (33, 33 ') is rotated in engagement with each other and thereby fit each other. Particulate gear teeth are pulverized, resulting in finer particles.

And the heavy oil (s) which is primarily a crushing action is a pair of gear rotating body that is secondly transported to another circulation hole (32 ') by the connecting pipe 25, the gear teeth are engaged with the inside of the gear teeth ( 33, 33 ') secondaryly crushes impurities such as fine particles.

On the other hand, a pair of gear rotating body (33,33 ') inside the circulation hole (32,32') is rotated by interlocking so that the gear teeth (symmetrical omission) between the interlocking gear teeth and thereby interlocking gear teeth As a result, the fine particles form fine impurities.

The secondary grinding of the pump-combining grinding means 30 not only enables the primary grinding to be pulverized in the second case but also in the case of the finely pulverized particles in the second time. It is to be crushed to become finer particles.

In addition, the pump-pulverizing means 30 rotates by engaging a pair of gear rotating bodies 33 and 33 'respectively located in the circulation holes 32 and 32', so that the pump serves to pump heavy oil s at the same time. To perform.

Referring back to Figure 1, the heavy oil (s) passed through the pump combined grinding means 30 is transferred to the shredding separation means 40 is processed.

In the present invention, the heavy oil (s) is introduced into the heavy oil (s) introduced into the shredding separation means 40 in the process of being transferred to the shredding separation means 40 in the pump combined grinding means (30).

Injecting air into the heavy oil (s) is to improve the combustion efficiency by increasing the oxygen content in the heavy oil (s) because the heavy oil (s) is a low-grade fuel oil, the present invention is to supply oxygen to the heavy oil (s) It is provided with the air injection means (50).

Referring to FIG. 1, the air input means 50 is a crushing separating means 40 through the solenoid valve 53 and the pressure regulator 54 in the air tank 52 which is stored by receiving compressed air from the compressor (51). It is made to flow through the heavy oil (s) transfer pipe connected to the inlet (41a) of the).

Referring to Figure 5 (a), (b), the crushing separating means 40 is a heavy oil into the fixed metal filter network 43 installed inside the outer cylinder 42 through the inlet (41a) of the main body 41 (s) is to flow in.

Inside the fixed metal filter net 43, there is provided a rotating metal filter net 45 which is rotated by the high speed motor 44 fixed to the upper plate member 41 '. Since the high speed motor 44 rotates at high speed at 1700 rpm / min, the rotating metal filter network 45 also rotates at high speed at the same speed.

In addition, the rotary metal filter net 45 is configured to rotate while maintaining a fine interval of 0.2-0.5mm between the fixed metal filter net 43 and. The rotating metal filter net 45 is a mesh of 300 mesh and the fixed metal filter net 43 is a mesh of 350 mesh is used.

Therefore, the heavy oil (s) introduced through the inlet (41a) passes through the fixed metal filter network 43 in the process of being discharged to the discharge port (41b) through the rotating metal filter network 43 and the fixed metal filter network (43). Particles or impurities that do not pass through may not pass through the fixed metal filter network 43.

At this time, since the rotating metal filter network 43 rotates at a high speed on the inner circumferential surface of the fixed metal filter network 43, particulates or impurities caught in the fixed metal filter network 43 are pulverized into smaller particles. 43).

In addition, since the rotating metal filter net 43 rotates at a high speed, the inside of the outer cylinder 42 is vortexed, so that the air introduced by the air input means 50 is mixed with the heavy oil s. As a result, the oxygen contained in the air is fused to heavy oil (s).

A moisture storage chamber 46 is provided below the discharge port 41b of the main body 41.

The moisture storage chamber 46 is to collect the water (w) contained in the heavy oil (s), the heavy oil (s) is discharged to the discharge port (41b) because the specific gravity of the water is higher than the specific gravity of the heavy oil (s). Due to the difference in specific gravity in the process, the water (w) sinks into the moisture storage chamber 46 and is accumulated.

The moisture storage chamber 46 is provided with a moisture detection sensor 47. The moisture detection sensor 47 is a sensor that detects this when the moisture (w) is collected in a predetermined amount or more in the moisture storage chamber 46.

Therefore, when the moisture detecting sensor 47 performs a sensing action, it is applied to a controller (not shown), and the controller sends a signal to operate the solenoid valve 48 to be opened. Since the moisture detection sensor 47 and the control unit and the solenoid valve 48 are already known, detailed descriptions and drawings will be omitted.

When the solenoid valve 48 is operated to open, the water 47 of the moisture storage chamber 46 is returned to the main fuel tank 1.

It is possible to return to the main fuel tank (1) without discarding the water (47), since the flowability is very low in the case of heavy oil (s), pure heavy oil (s) alone has low flowability to a small diameter pipe, but heavy oil (s) If there is moisture in the fluidity is not only good because it can be transported smoothly, as well as to discard the water (w) in the ocean can be returned to the main fuel tank (1) because it may cause marine pollution.

Accordingly, the heavy oil s that has passed through the shredding separation means 40 is treated in the state of heavy oil s in which oxygen is melted and water (w) is separated at the same time as fine particles or impurities are broken into smaller particles. As shown in the flow stop sedimentation means 60, the heating sedimentation means 70 and the filter sedimentation means 80 is transferred to allow impurities to precipitate.

6 shows the flow arrest sedimentation means 60.

The flow stop sedimentation means (60) has an elongated settling chamber (62) and a standing tank (61) having an outlet (63) at the top and a drain valve (64) at the bottom.

In addition, the inlet pipe 65 for supplying heavy oil (s) to the settling chamber 62 is provided with a heavy oil (s) is supplied to the lower side of the settling chamber 62 and then lowered in the settling chamber 62 The inflow pipe 65 is provided so that the discharge port 65a may be located in it.

In addition, a plurality of settling plate members 66 having a plurality of small pores 65a are closed in order to prevent the heavy oil s rising upward in the settling chamber 62 to impinge the impurity k to sink downward. It is fixed at equal intervals in the direction.

Therefore, the heavy oil (s) discharged to the discharge port (65a) of the inlet pipe 65 is raised to the upper side at this time is raised through the small hole (66a) of the precipitation plate member 66 is discharged to the discharge port (63). .

Therefore, the heavy oil s moved upwardly toward the settling chamber 62 is hit by the settling plate member 66 to prevent the flow thereof, whereby the heavy oil s has a gradually rising flow.

Therefore, impurities (k) contained in the heavy oil (s) hit the sedimentation plate member 66 while the heavy oil (s) is gradually moved upwardly so that the impurities (k) are swept together with the heavy oil (s). As a result, impurities (k) having a higher specific gravity than heavy oil (s) sink to the bottom and accumulate under the settling chamber 62 of the standing tank 71. The accumulated impurities k are drain valves 64. ) To be discharged regularly.

The heavy oil s that has passed through the flow arrest sedimentation means 60 is treated to remove impurities k again from the filter sedimentation means 80 after the impurities k are removed again from the heating sedimentation means 70.

7 shows the heat sedimentation means 70 and the filter sedimentation means 80.

The heating and sedimentation means 70 is an electric heater in which heavy oil (s) introduced into the sedimentation chamber 73 through the inlet 72 at the lower side of the long standing tank 71 is long embedded in the sedimentation chamber 73 ( 74) to be heated.

While heavy oil (s) is transported from the service fuel tank (10), the temperature is lowered and the fluidity is in a very distant state, so that the flow in the pipe becomes poor, and the impurities (k) contained in the heavy oil (s) The subsidence due to the difference in specific gravity will not separate properly, and this phenomenon is more severe in winter.

Therefore, the viscosity of the heavy oil (s) is lowered by allowing the heavy oil (s) having a high viscosity, especially in winter, to be heated by the electric heater (74).

Therefore, the impurity (k) having a higher specific gravity than the heavy oil (s) sinks in the process of moving the heavy oil (s) having a lower viscosity from the lower side of the settling chamber (73) to the outlet (75). The accumulated impurities k are to be discharged through the drain valve 76.

That is, the heat precipitating means 70 heats heavy oil (s) having a high viscosity and low fluidity due to a drop in temperature, thereby improving fluidity, thereby facilitating transfer, and at the same time, lowering the viscosity of heavy oil (s) to reduce impurities (k). ) Is to be settled down well to be separated and to be removed through the drain valve (76).

On the other hand, the filter sedimentation means 80 is such that heavy oil (s) is introduced into the settling chamber 83 through the inlet port 82 in the lower side of the long standing tank 81 as shown in FIG.

Heavy oil (s) introduced into the settling chamber (83) is raised to the upper portion while passing through the metal filter net 84 of 350-400 mesh (k) is to be filtered.

The heavy oil (s) passing through the metal filter net 84 is flowed backward through the discharge hole (86) opened in the upper portion of the discharge pipe (85) standing in the center of the precipitation chamber 83 is discharged to the discharge port (87). It is.

As described above, the discharge pipe 85 standing up in the middle of the settling chamber 83 and the discharge hole 86 formed at the upper end thereof to discharge the heavy oil (s) are the heavy oil introduced into the settling chamber 83 (s). ) Is discharged upwardly so that the impurity (k) having a specific gravity higher than that of heavy oil (s) can be settled downward while the impurity (k) is also formed by the metal filter net (84). It is intended to have a more enhanced filtration capacity by allowing to be filtered.

Therefore, the impurities k precipitated below the settling chamber 83 are discharged through the drain valve 88 to be removed.

On the other hand, the filter sedimentation means 80 has a structure for cleaning the metal filter net 84.

That is, the metal filter net 84 is connected to the upper plate member 81a by the connecting member 81b, and the upper plate member 81a is detached by fastening or releasing the bolt 89 from the standing tank 81. It is intended to be combined. However, in some cases, the bolt 89 may be coupled to a fastening structure other than the fastening structure.

Therefore, the metal filter mesh 84 is removed by removing the upper plate member 81a by removing the bolt (89) in order to clean regularly, and withdraw the metal filter mesh 84 from the settling chamber 83 and then cleaned To reunite.

Next, the heavy oil s passed through the filter sedimentation means 80 is transferred to the ultrasonic emulsification means 90.

The ultrasonic emulsifying means (90) has a housing (91) having an emulsification chamber (94) having an inlet (92) and an outlet (93) through which heavy oil (s) enters and exits, as shown in FIG. 94, there is provided an ultrasonic vibrator (96) which stands by vibrating by the ultrasonic oscillator (95) to generate ultrasonic waves. The ultrasonic vibrator 96 is typically used a titanium horn.

Since the ultrasonic oscillator 95 generates a lot of heat during operation, the cooling fan 97 is installed on the ultrasonic oscillator 95. Since the ultrasonic oscillator 95 and the ultrasonic vibrator 96 are known devices, detailed descriptions and drawings will be omitted.

Therefore, the heavy oil (s) introduced into the emulsification chamber (94) causes physical properties and chemical reactions to the heavy oil (s) by ultrasonic waves irradiated from the ultrasonic vibrator (96), so that heavy oil (s) is crushed, stirred, and fuel molecules. It causes the dissolution and agglomeration of the ring to cause emulsification.

The ultrasonic wave is generated when 18,000 to 20,000 vibrations per minute is generated in the ultrasonic vibrator 96, and since it is a known fact already known by academia or the prior art regarding the emulsification by the ultrasonic wave, Detailed description will be omitted.

However, the present invention is emulsified because the heavy oil (s) flowing into the emulsification chamber 94 has been processed to be removed by precipitating or filtering in the state in which impurities are pulverized into smaller particles by the respective treatment means described above. The impurities k contained in the heavy oil s introduced into the seal 94 may be referred to as very small particulate states.

For example, if the particulates introduced into the emulsification chamber 94 are in the form of large particulates, it may take a long time to grind them by ultrasonic waves, or may not be able to be ground by ultrasonic waves. This may cause clogging of the fuel circulation system, or result in poor ignition and incomplete combustion of the combustion.

However, in the present invention, since the impurities contained in the heavy oil s are processed to be removed by being precipitated or filtered in the state of being pulverized into smaller particles, the impurities contained in the heavy oil s introduced into the emulsification chamber 94 (k). ) Is an extremely small particulate state, and as a result, it is not only pulverized into smaller particles by ultrasonic waves, but also pulverizes quickly, so that it does not block the fuel circulation system of the diesel engine, promotes ignition of combustion, and improves combustion efficiency. Will be.

Moreover, when two or more ultrasonic emulsifying means 90 are used as shown in FIG. Since it is processed to work, the quality of heavy oil (s) is improved to be better used as a diesel engine fuel.
