Impact-resistant oil storage bulkheads

Abstract

The present invention relates to the field of oil storage tanks of floating production storage vessels, and specifically discloses an impact-resistant oil storage tank wall, comprising an outer oil storage cylinder, an inner oil storage cylinder disposed inside the outer oil storage cylinder, a reinforced support pipe disposed between the inner oil storage cylinder and the outer oil storage cylinder, a pipe connector consisting of multiple spiral pipes, cooling pipes connected to both ends of the pipe connector, a buffer mechanism disposed inside the limit slot, the buffer mechanism comprising: a spherical guide block, a guide ramp, and an adjustment screw. The spherical guide block is disposed below the oil storage pipeline and can act as a buffer when the oil body above is transported to the lower tank of the oil storage pipeline, thereby consuming a certain amount of potential energy contained in the oil body impacted at high speed. The guide ramp disposed at the end of the spherical guide block can diffusely guide the oil body outward after being buffered by the spherical guide block, thereby reducing the impact force on the inner oil storage cylinder per unit area.

Description

Technical Field

[0001] The invention relates to the field of oil storage tanks of floating production storage and offloading vessels, in particular to an impact-resistant oil storage tank wall. Background Art

[0002] FPSOs (Floating Production Storage and Offloading) are large, comprehensive offshore oil production bases that separate extracted oil and gas, treat oily wastewater, generate power, provide heat, store and transport crude oil products, and integrate personnel accommodation and production control systems. Compared to other oil production platforms, FPSOs offer strong wind and wave resistance, wide water depth adaptability, large oil storage and offloading capacity, and are transportable and reusable. FPSO oil and gas processing systems are largely similar to onshore oil and gas processing systems, including oil, gas, and water separation systems, metering systems, wastewater treatment systems, and flare combustion systems. The difference lies in the more compact overall layout and stricter safety regulations of FPSO oil and gas processing systems. While ensuring smooth process flows, the layout of key modules must conform to the ship's motion requirements and allow ample maintenance space. FPSOs feature a more highly integrated and comprehensive automated control system than onshore platforms, and the selection of oil and gas processing equipment strives for efficiency and compactness. Because FPSOs can store and offload more oil per unit time than traditional tankers, they are widely used.

[0003] However, because the oil in the floating production storage vessel flows at a high speed when storing oil, the potential energy contained in the oil is large, so it is easy to impact the bulkhead of the oil storage tank for a long time, reducing its service life. Summary of the Invention

[0004] In view of the existing problems, the present invention provides an impact-resistant oil storage tank wall, which can effectively solve the problems raised in the background technology when used in conjunction with other devices.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions:

[0006] The impact-resistant oil storage tank wall includes an outer oil storage cylinder, an inner oil storage cylinder is arranged inside the outer oil storage cylinder, a reinforcement support tube is arranged between the inner oil storage cylinder and the outer oil storage cylinder, an inner side wall of the inner oil storage cylinder is installed with inner teeth, a cooling pipe is installed between the inner oil storage cylinder and the outer oil storage cylinder at the interval of the reinforcement support tube, the cooling pipe is composed of a plurality of spiral pipes, both ends of the cooling pipe are connected with cooling pipes, one end of the cooling pipe passes through the end of the outer oil storage cylinder and is connected to a water injection pipe, the reinforcement support pipe is located near the end of the water injection pipe and passes through the end of the outer oil storage cylinder and is connected to an air injection pipe, the outer side wall of the outer oil storage cylinder is installed with an oil storage pipe, the inner side wall of the oil storage pipe is provided with a limiting slot, and a buffer mechanism is arranged inside the limiting slot, and the buffer mechanism includes: a spherical guide block, a guide inclined plate, and an adjusting screw.

[0007] As a further solution of the present invention: a cross block is installed at the upper end of the adjusting screw rod, and a limit stopper is installed at the lower end of the adjusting screw rod.

[0008] As a further solution of the present invention: the cooling pipe is located at one end away from the water injection pipe and passes through the end of the oil storage outer cylinder and is connected to a drainage pipe, and a maintenance pipe is installed on one side of the oil storage pipe outside the oil storage outer cylinder.

[0009] As a further solution of the present invention: a reinforcement sleeve is installed inside the reinforced support tube, and a gas injection interface is connected between the reinforcement sleeve and the gas injection pipeline.

[0010] As a further solution of the present invention: the spherical guide block is engaged and rotatably connected with the adjusting screw rod, and the limit block is fixedly connected with the adjusting screw rod.

[0011] As a further solution of the present invention: the cooling pipe is connected to the cooling pipe and the water injection pipe, and the reinforcement support pipe is fixedly connected to the inner oil storage cylinder and the outer oil storage cylinder.

[0012] As a further solution of the present invention: the inner latching teeth are fixedly arranged on the inner side wall of the inner oil storage cylinder.

[0013] As a further solution of the present invention: the drainage pipe is connected to the cooling pipe.

[0014] As a further solution of the present invention: the reinforcement sleeve is fixedly connected to the inside of the reinforcement support tube.

[0015] As a further solution of the present invention: the buffer mechanism is clamped inside the limiting clamping slot through the cross clamping block.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The reinforcement sleeve is fixedly connected to the inside of the reinforcement support tube. The reinforcement support tube adopts a regular hexagonal imitation honeycomb structure, which can provide good support strength. A gas injection interface is connected between the reinforcement sleeve and the gas injection pipeline. Inert gas is injected into the interior of the reinforcement support tube through the gas injection interface to reduce vibration and noise caused by impact.

[0018] 2. The spherical guide block is engaged and rotatably connected with the adjusting screw. The spherical guide block is controlled to rotate on the outside of the adjusting screw to adjust the distance to the oil storage pipeline. The impact of oil bodies with different flow rates can be controlled. At the same time, the whole is connected to the inside of the limit slot through a cross clamping block, and can be freely installed and disassembled without affecting normal oil storage and unloading operations.

[0019] 3. The spherical guide block is set at the bottom of the oil storage pipeline. It can play a buffering role when the oil above is sent to the oil storage pipeline in the lower tank, and consume the potential energy contained in the high-speed impact oil to a certain extent. The guide inclined plate set at the end of the spherical guide block can diffuse the oil outward after being buffered by the spherical guide block, so as to reduce the impact force on the inner oil storage cylinder per unit area.

[0020] 4. The cooling pipe and the reinforced support pipe are both arranged in a spiral shape between the outer oil storage cylinder and the inner oil storage cylinder, which can increase the contact area with the outer oil storage cylinder and the inner oil storage cylinder, and reinforce the support pipe as a whole to play a role in resisting impact and increasing strength. The reinforced support pipe is fixedly connected to the inner oil storage cylinder and the outer oil storage cylinder, so that the inner oil storage cylinder and the outer oil storage cylinder form a whole. Therefore, the oil storage device as a whole has a double-layer structure, which increases the overall strength of the device and improves the impact resistance. The cooling pipe is used to transport cooling water to reduce the temperature of the oil stored in the inner oil storage cylinder, and avoid the temperature rise of the oil after the impact caused by the oil being transported in the tank.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] In the description of this specification, the reference terms "this embodiment", "some embodiments", "example", "specific example", or "some examples" mean that the specific features, structures, materials or characteristics described in combination with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example, and the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0030] like Figure 1-6As shown, this embodiment provides an impact-resistant oil storage tank wall, including an outer oil storage cylinder 1, an inner oil storage cylinder 6 is arranged inside the outer oil storage cylinder 1, and a reinforcement support pipe 602 is arranged between the inner oil storage cylinder 6 and the outer oil storage cylinder 1. The reinforcement support pipe 602 is fixedly connected to the inner oil storage cylinder 6 and the outer oil storage cylinder 1, so that the inner oil storage cylinder 6 and the outer oil storage cylinder 1 form a whole. Therefore, the oil storage device as a whole is a double-layer structure, which increases the overall use strength of the device and improves the impact resistance. The inner side wall of the inner oil storage cylinder 6 is installed with an inner tooth 601, and the inner oil storage cylinder 6 is fixed with the outer oil storage cylinder 1. A cooling pipe 702 is installed between the outer oil storage cylinder 1 and the reinforcement support pipe 602. The cooling pipe 702 is composed of multiple spiral pipes. The cooling pipe 702 and the reinforcement support pipe 602 are spirally arranged between the outer oil storage cylinder 1 and the inner oil storage cylinder 6, which can increase the contact area with the outer oil storage cylinder 1 and the inner oil storage cylinder 6. The reinforcement support pipe 602 as a whole plays the role of resisting impact and increasing strength. The cooling pipe 702 is used to transmit cooling water to reduce the temperature of the oil stored in the inner oil storage cylinder 6, avoiding the temperature of the oil after the impact caused by the oil delivery tank. The temperature rises, and both ends of the cooling pipe 702 are connected with a pipe connector 701. One end of the pipe connector 701 passes through the end of the oil storage outer cylinder 1 and is connected to the water injection pipe 7. The pipe connector 701 is connected with the cooling pipe 702 and the water injection pipe 7. The outer wall of the oil storage outer cylinder 1 is installed with an oil storage pipe 2. The inner wall of the oil storage pipe 2 is provided with a limit card groove 4. The interior of the limit card groove 4 is provided with a buffer mechanism 5. The buffer mechanism 5 includes: a spherical guide block 502, a guide inclined plate 503, and an adjusting screw rod 504. The spherical guide block 502 is provided with a limit card groove 4. Below the oil storage pipeline 2, it can play a buffering role when the oil body above is sent to the oil storage pipeline 2 in the lower tank, and consume the potential energy contained in the high-speed impact oil body to a certain extent. The guide inclined plate 503 arranged at the end of the spherical guide block 502 can diffuse the oil body outward after being buffered by the spherical guide block 502, so as to reduce the impact force on the inner oil storage cylinder 6 per unit area. A cross block 501 is installed on the upper end of the adjusting screw rod 504, and the buffer mechanism 5 is clamped to the inside of the limit slot 4 through the cross block 501.

[0031] like Figure 2-4As shown, in this embodiment, a limit stopper 505 is installed at the lower end of the adjusting screw rod 504, and the limit stopper 505 is fixedly connected to the adjusting screw rod 504. The outer diameter of the limit stopper 505 is larger than the mounting hole diameter of the adjusting screw rod 504, and the spherical guide block 502 is engaged and rotatably connected with the adjusting screw rod 504. The spherical guide block 502 is controlled to rotate as a whole on the outside of the adjusting screw rod 504 to adjust the distance to the oil storage pipe 2. Due to the impact of the oil body with different flow rates, the impact of the oil body can be controlled. At the same time, the buffer mechanism 5 is connected to the inside of the limit slot 4 as a whole through the cross block 501, and can be freely installed and disassembled. The pipe connector 701 is located at the end away from the water injection pipe 7 and passes through the end of the oil storage outer cylinder 1 and is connected to the drain The water pipe 8 and the drainage pipe 8 are connected through the pipe connector 701. One side of the oil storage pipe 2 is located on the outside of the oil storage outer cylinder 1 and is installed with an inspection pipe 3. The reinforcement support pipe 602 is located near one end of the water injection pipe 7 and passes through the end of the oil storage outer cylinder 1 and is connected to the gas injection pipe 9. A reinforcement sleeve 603 is installed inside the reinforcement support pipe 602. The reinforcement sleeve 603 is fixedly connected to the inside of the reinforcement support pipe 602. The reinforcement support pipe 602 adopts a regular hexagonal imitation honeycomb structure, which can provide good supporting strength. A gas injection interface 604 is connected between the reinforcement sleeve 603 and the gas injection pipe 9. Inert gas is injected into the inside of the reinforcement support pipe 602 through the gas injection interface 604 to reduce vibration and noise caused by impact.

[0032] The working principle of the present invention is as follows: the cooling pipe 702 and the reinforcement support pipe 602 are both arranged in a spiral shape between the outer oil storage cylinder 1 and the inner oil storage cylinder 6, which can increase the contact area with the outer oil storage cylinder 1 and the inner oil storage cylinder 6, and the reinforcement support pipe 602 as a whole plays the role of resisting impact and increasing strength. The reinforcement support pipe adopts a regular hexagonal imitation honeycomb structure, which can play a good supporting strength. The honeycomb structure can disperse and bear external forces from all directions, so that the honeycomb structure has higher resistance to extrusion force than a circular or square structure. The structure is very sophisticated, applicable and saves materials. At the same time, the outer oil storage cylinder 1 and the inner oil storage cylinder 6 are set as a double-layer structure, which can also increase the use strength of the entire device, reduce the overall mass of the oil storage tank and increase its impact resistance. Inert gas is injected into the interior of the reinforcement support pipe 602 through the gas injection interface 604 to reduce vibration and noise caused by impact. Water is injected into the interior of the pipe connector 701 through the water injection pipe 7. The cooling water is transmitted in the cooling pipe 702 and then discharged through the drainage pipe 8. Circulating water is used to reduce the oil stored in the inner oil storage cylinder 6. The temperature of the oil body is reduced to avoid the temperature rise of the oil after the impact caused by the oil body being sent to the tank. When the oil is transported through the oil storage pipeline 2, the spherical guide block 502 is set at the bottom of the oil storage pipeline 2. It can play a buffering role when the oil body above is sent to the oil storage pipeline 2 downward, and consume the potential energy contained in the oil body under high-speed impact to a certain extent. The guide inclined plate 503 set at the end of the spherical guide block 502 can divert the oil body to the outside after being buffered by the spherical guide block 502, so as to reduce the impact force on the inner oil storage cylinder 6 per unit area. The limit stopper 505 is fixedly connected to the adjusting screw rod 504. The outer diameter of the limit stopper 505 is larger than the mounting hole diameter of the adjusting screw rod 504. The spherical guide block 502 is engaged and rotatably connected with the adjusting screw rod 504. The spherical guide block 502 is controlled to rotate as a whole on the outside of the adjusting screw rod 504 to adjust the distance to the oil storage pipeline 2. The impact of the oil body with different flow rates can be controlled. At the same time, the buffer mechanism 5 is connected to the inside of the limit slot 4 as a whole through the cross block 501, and can be freely installed and disassembled.
