Description

Technical Field

[0001] This invention relates to the field of marine technology, and in particular to an oil sludge purification device, a marine power system, and a ship. Background Technology

[0002] Marine propulsion systems typically include fuel-oil separators to purify fuel oil and lubricating oil sludge. These separators remove water and sludge, separating the oil sludge from the water. The oil sludge is then collected by an oil sludge purification system and either incinerated or pumped ashore for recycling. Because the oil separator carries away a significant amount of water during the oil sludge separation process, if this excess water is not removed before incineration, a large amount of diesel fuel is required for ignition. Even without incineration on board, the cost of pumping the oil sludge ashore for recycling is very high.

[0003] Existing shipboard oil sludge treatment systems typically involve collecting oil sludge in a settling tank, allowing water to settle, and then transferring the sludge to an incinerator for combustion, thus saving on diesel fuel consumption. The settling tank is equipped with a steam coil immersed in the oil solution, which heats the sludge, reduces its viscosity, and accelerates the settling of water and mechanical impurities to the bottom due to their density difference. Finally, the water is manually drained into the bilge tank via a self-closing valve.

[0004] However, when the oil in the aforementioned oil sludge settling tank is heated, a large amount of water vapor mixes with the oil and rises, gushing out of the chimney in large quantities, causing water and oil to drip onto the deck, polluting the ship's environment, and making it impossible to completely recover the water and oil.

[0005] Therefore, there is an urgent need for oil residue purification equipment, marine power systems, and ships to solve the above problems. Summary of the Invention

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] Figure 1 A schematic diagram of an oil sludge purification device provided in an embodiment of the present invention is shown. (Refer to...) Figure 1 This embodiment provides an oil sludge purification device, a marine propulsion system, and a ship. The marine propulsion system includes the oil sludge purification device provided in this embodiment. The oil sludge purification device is configured to purify fuel oil sludge and lubricating oil sludge after use by the marine propulsion system. The ship includes a deck 10 and the aforementioned marine propulsion system, which is configured to provide power to the ship. The oil sludge sedimentation device 100 is disposed below the deck 10, and a portion of the forced evaporation device 200 can extend above the deck 10 for exhaust.

[0031] The oil sludge purification equipment provided in this embodiment includes an oil sludge sedimentation device 100 and a forced evaporation device 200. The oil sludge sedimentation device 100 includes a sedimentation tank 110 and a heating component 120. The sedimentation tank 110 contains oil sludge to be dehydrated, and the heating component 120 is disposed within the sedimentation tank 110 and configured to heat the oil sludge. By heating the oil sludge to be dehydrated using the heating component 120, the viscosity of the oil sludge is reduced, and the process of water and impurities in the oil sludge settling to the bottom of the sedimentation tank 110 due to density differences is accelerated, thereby improving the water removal effect in the oil sludge. In this embodiment, the heating component 120 can specifically be a steam coil as used in the prior art.

[0032] Specifically, the forced evaporation device 200 includes an exhaust assembly 210 and a hydrophobic assembly 220. The exhaust assembly 210 is disposed on the settling tank 110. In this embodiment, the exhaust assembly 210 is specifically disposed on the top of the settling tank 110, and is configured to extract water vapor from the settling tank 110. The hydrophobic assembly 220 is disposed in the exhaust path of the exhaust assembly 210, and can perform gas-liquid separation of water vapor. The separated gas can be discharged from the hydrophobic assembly 220. Through the exhaust assembly 210, water vapor generated by heating in the settling tank 110 can be actively extracted, and the hydrophobic assembly 220 can be used to separate the gas and liquid in the water vapor, so as to avoid water and oil in the discharged gas dripping onto the deck 10 and causing environmental pollution on the ship.

[0033] More specifically, the oil residue purification equipment also includes an incinerator 300 and an auxiliary fuel oil supply device 400. The auxiliary fuel oil supply device 400 is connected to the incinerator 300 and is configured to supply fuel to the incinerator 300. The incinerator 300 is connected to the settling tank 110, and the dehydrated oil residue in the settling tank 110 can enter the incinerator 300 for incineration.

[0034] More specifically, the oil sludge settling device 100 also includes an overflow valve 150. The overflow valve 150 is connected to the settling tank 110 and is positioned at a height lower than that of the exhaust assembly 210. In this embodiment, the overflow valve 150 is specifically located on the side of the settling tank 110. When the liquid level of the oil sludge to be dewatered in the settling tank 110 rises to the height of the overflow valve 150, it can flow out from the overflow valve 150. The overflow valve 150 prevents the liquid level in the settling tank 110 from becoming too high, thus avoiding the problem of the oil sludge to be dewatered entering the exhaust assembly 210. In this embodiment, the... More specifically, the oil sludge sedimentation device 100 also includes a drain valve 160. The drain valve 160 is located at the bottom of the sedimentation tank 110 and is configured to drain the water from the sedimentation tank 110. Water and impurities that settle to the bottom of the sedimentation tank 110 under sedimentation can be discharged to an external collection device through the drain valve 160. After it is determined that all the water in the sedimentation tank 110 has been drained, the dehydrated oil sludge is then discharged into the incinerator 300 for incineration. In this embodiment, the drain valve 160 can specifically be a solenoid valve as used in the prior art.

[0035] Preferably, the oil sludge settling device 100 further includes a circulation pipeline 130 and a stirring assembly 140. The inlet and outlet of the circulation pipeline 130 are both connected to the settling tank 110, and the inlet of the circulation pipeline 130 is positioned lower than the outlet. The stirring assembly 140 is disposed within the circulation pipeline 130 and configured to stir the oil sludge to be dehydrated. The stirring assembly 140 can stir the oil sludge to be dehydrated, increasing its fluidity and heat exchange area, which is more conducive to improving the settling effect. In this embodiment, the stirring assembly 140 can specifically be a stirring pump as used in the prior art.

[0036] Figure 2 A schematic diagram of a hydrophobic component provided in an embodiment of the present invention is shown. (Refer to...) Figure 1 and Figure 2The hydrophobic assembly 220 includes a condenser 221 and a water recovery unit (not shown). The inlet of the condenser 221 is connected to the exhaust assembly 210, allowing water vapor discharged from the settling tank 110 via the exhaust assembly 210 to be condensed in the condenser 221, achieving liquid-gas separation. The outlet of the condenser 221 is configured to discharge gas. The water recovery unit is connected to the drain pipe 224 of the condenser 221 and is configured to recover liquid from the condenser 221.

[0037] Specifically, the hydrophobic component 220 also includes an inlet pipe 222 and an outlet pipe 223. The inlet pipe 222 and the outlet pipe 223 are respectively connected to the condenser 221. Water vapor can enter the condenser 221 through the inlet pipe 222, and gas can exit the condenser 221 through the outlet pipe 223. The outlet of the inlet pipe 222 and the inlet of the outlet pipe 223 are not directly opposite each other and are vertically offset. This offset arrangement of the inlet pipe 222 and the outlet pipe 223 prevents water vapor entering the condenser 221 from directly flowing out of the outlet pipe 223, increasing the length of the water vapor's flow path in the condenser 221 and improving the gas-liquid separation effect.

[0038] Figure 3 A schematic diagram of an exhaust assembly provided in an embodiment of the present invention is shown. (Refer to...) Figure 1 and Figure 3 The forced evaporation device 200 also includes an exhaust assembly 230. The exhaust assembly 230 includes a vent pipe 231 and a waterproof cover 232. The vent pipe 231 is connected to the gas outlet of the hydrophobic assembly 220 and extends above the deck 10. The outlet end of the vent pipe 231 is bent and extends downwards in a vertical direction. The waterproof cover 232 is disposed at the outlet end of the vent pipe 231 and is configured to collect liquid dripping from the outlet end of the vent pipe 231. The vent pipe 231 allows for smooth exhaust of the oil sludge purification equipment, while the waterproof cover 232 prevents water and oil mixed in the exhaust from dripping onto the deck 10.

[0039] Specifically, the exhaust assembly 230 also includes a return pipe 233, which connects the waterproof cover 232 and the gas outlet of the hydrophobic assembly 220. This return pipe 233 guides liquid dripping from the outlet end of the vent pipe 231 along the gas outlet of the hydrophobic assembly 220. Liquid in the waterproof cover 232 can flow back to the condenser 221 along the inner walls of the return pipe 233 and the outlet pipe 223 for further gas-liquid separation.

[0040] More specifically, the exhaust assembly 230 also includes a fire-resistant structure 239. The fire-resistant structure 239 includes a housing and a fine mesh. The housing is conical with internal flow channels for guiding gas flow; the conical structure facilitates installation and enhances the flow guidance effect. The fine mesh is located at the outlet end of the conical housing and utilizes a quenching effect to achieve flame arrest.

[0041] More specifically, the aforementioned waterproof cover 232 includes an upper cover 234 and a lower cover 235 that are interlocked with each other. This design facilitates the disassembly and cleaning of the waterproof cover 232.

[0042] More specifically, the aforementioned waterproof cover 232 also includes a bracket 236. The bracket 236 is supported between the lower cover 235 and the deck 10, ensuring the reliable installation of the waterproof cover 232.

[0043] More specifically, the aforementioned waterproof cover 232 further includes a first guide member 237 and a second guide member 238. The first guide member 237 is disposed on the side of the upper cover 234 facing the lower cover 235, and the second guide member 238 is disposed on the side of the lower cover 235 facing the upper cover 234. The first guide member 237 and the second guide member 238 are staggered to form an S-shaped flow channel to facilitate exhaust. During the exhaust process, the first guide member 237 and the second guide member 238 are used to achieve condensation, which facilitates the condensation of liquid in the airflow.
