Description

Technical Field

[0001] The invention relates to the technical field of oil-water treatment, in particular to oil-water treatment equipment for ethane oil transfer arm raffinate purge. Background Art

[0002] During large-scale ocean shipping, ethane is loaded and unloaded using dedicated cryogenic loading arms. The temperature inside the loading arms is usually kept below -88.6°C, ensuring the delivery of liquid ethane. After the ethane is transported, some liquid ethane will remain in the oil transfer arm. To clean up this liquid ethane, high-temperature steam purging is usually used. Steam is injected from the high end of the oil transfer arm. After entering the oil transfer arm, the steam will heat the liquid ethane in the oil transfer arm and evaporate it into gas. The ethane gas and part of the steam are discharged through the bottom of the oil transfer arm to complete the purging work. During the purging, a container is usually set up at the exhaust end to collect the purged ethane. However, since the steam will also be condensed and liquefied into water when evaporating the ethane liquid, as the steam flows to the bottom of the oil transfer arm, the temperature will become lower and lower, and the condensed water will eventually solidify into ice particles, which will be collected along with the ethane gas. As the number of ice cubes increases, the container will easily be blocked, which will easily affect the collection of ethane gas. In addition, the ethane gas and ice cubes in the container are mixed together and need to be separated later, which is more cumbersome to operate. Summary of the Invention

[0017] See also Figures 1-9 The present invention provides a technical solution: an oil-water treatment device for purging residual liquid from an ethane oil transfer arm 1, comprising an oil transfer arm 1 and a frame 2, a gas cylinder 3 for receiving ethane gas and steam purged from the oil transfer arm 1 being installed on the frame 2; a conical cylinder 4 is provided in the gas cylinder 3, and the conical cylinder 4 is sealed and fitted with the inner wall of the gas cylinder 3; The frame 2 is provided with a purge mechanism, which is used to blow steam into the oil transfer arm 1 to purge the residual ethane liquid; A sealing mechanism is provided in the gas cylinder 3, which is used to ensure the sealing between the gas cylinder 3 and the conical cylinder 4 when the sealing member shrinks due to low temperature when ethane gas and steam are blown into the gas cylinder 3; A discharge mechanism is provided in the conical cylinder 4, which is used to discharge the ice cubes accumulated in the cylinder 3 while keeping the cylinder 3 sealed. The discharge mechanism includes a collecting assembly, which is used to collect the ice cubes scattered on the inner wall of the cone 4 to the central part of the cone 4, and at the same time transport the ice cubes in the central part to the bottom of the cone 4; A discharge assembly is provided at the bottom of the cone 4. The discharge assembly is used to seal the bottom of the cone 4 and automatically discharge the ice cubes from the cone 4 while maintaining the seal on the bottom of the cone 4 when ice cubes gather at the bottom of the cone 4. During operation, the purge mechanism is activated to blow high-temperature steam into the oil transfer arm 1. The residual liquid ethane in the oil transfer arm 1 is rapidly heated and vaporized under the action of the high-temperature steam, and then enters the gas cylinder 3 together with the high-temperature steam. As the high-temperature steam and ethane gas in the gas cylinder 3 increase, the conical cylinder 4 will gradually move downward under the action of the air pressure, thereby expanding the capacity of the gas cylinder 3. Since the boiling point of ethane is -88.6°C, the inside of the oil transfer arm 1 is in a low-temperature environment. When the steam evaporates the ethane liquid, it will also be condensed and liquefied into water. As the steam flows to the bottom of the oil transfer arm 1, the temperature will become lower and lower, and the condensed water will eventually solidify into ice particles. The ice particles will enter the gas cylinder 3 along with the ethane gas. In order to prevent the accumulation of ice in the gas cylinder 3 and affect the air intake of the gas cylinder 3, the ice scattered on the inner wall of the cone 4 can be collected to the central part by activating the collection component, and then the ice in the central part can be transported to the bottom of the cone 4; when the ice accumulates at the bottom of the cone 4, the ice at the bottom of the cone 4 can be discharged from the cone 4 by the discharge component, and the sealing of the bottom of the cone 4 can be ensured during the discharge process. Since the ethane gas blown into the gas cylinder 3 still has a relatively low temperature, the seal between the gas cylinder 3 and the tapered cylinder 4 shrinks under the action of low temperature, which may cause the ethane gas in the gas cylinder 3 to leak. The sealing mechanism can ensure the sealing between the gas cylinder 3 and the tapered cylinder 4 when the seal between the gas cylinder 3 and the tapered cylinder 4 shrinks, thereby effectively preventing the leakage of ethane gas in the gas cylinder 3.

[0018] See Figure 4-Figure 5 、 Figure 9 The collecting assembly includes a rotating frame 5 rotatably connected to the upper part of the conical cylinder 4, and three arc-shaped scrapers 6 are fixedly connected to the rotating frame 5. The arc-shaped scrapers 6 are in contact with the inner wall of the conical cylinder 4; a rotating unit is provided on the rotating frame 5, and the rotating unit is used to drive the rotating frame 5 to rotate; The rotating unit includes a motor 7 mounted above the rotating frame 5. Telescopic rods 8 are symmetrically fixed to the motor 7 in front and back positions. The upper ends of the telescopic rods 8 are fixedly connected to the air cylinder 3. The output shaft of the motor 7 is fixedly connected to the rotating frame 5. The motor 7 is a permanent magnet synchronous motor with bearings lubricated with low-temperature gentle grease, high-performance rare earth magnets, polyimide windings, and fluoroplastic insulation. During operation, when ethane gas and crushed ice are blown into the air cylinder 3, the crushed ice will be scattered on the inner wall of the conical cylinder 4. At this time, the motor 7 is started, and the motor 7 drives the rotating frame 5 to rotate. The rotating frame 5 will drive several arc-shaped rods connected thereto to rotate with the rotating frame 5. The arc-shaped rods will scrape the ice scattered on the inner wall of the conical cylinder 4. After the ice is loosened, it will automatically fall to the center of the conical cylinder 4. Since the air cylinder 3 is a low-temperature environment, the low-temperature soft grease can ensure that the lubrication effect of the motor 7 bearing is not affected by the low temperature, and the magnet and winding can work normally in a low-temperature environment.

[0019] See Figure 4-Figure 6The discharge assembly includes an auger 9 arranged in the conical cylinder 4. The interior of the auger 9 is hollow and the upper part of the auger is slidably connected to a driving rod 10, which is fixedly connected to the rotating frame 5. A spring 11 is provided inside the auger 9, and the upper and lower ends of the spring 11 are fixedly connected to the driving rod 10 and the auger 9 respectively; a sealed discharge unit is provided at the bottom of the conical cylinder 4, which is used to discharge the ice cubes accumulated at the bottom of the conical cylinder 4 in a sealed state; The sealed discharge unit includes a sealing frame 12 fixed to the bottom of the conical cylinder 4. The sealing frame 12 is connected to the conical cylinder 4 and a sealing block 13 is slidably connected to the sealing frame 12. The sealing block 13 is provided with a vertically penetrating notch 14 at the discharge end of the conical cylinder 4; a second notch 15 is provided at the bottom of the sealing frame 12 near the rear; a cylinder 16 is fixedly connected to the frame 2, and the telescopic end of the cylinder 16 is fixedly connected to the sealing block 13; a displacement sensor 17 is provided inside the auger 9, and the upper and lower ends of the displacement sensor 17 are fixedly connected to the drive rod 10 and the auger 9 respectively; the bottom end of the auger 9 is located on the upper side of the sealing frame 12; During operation, when the crushed ice cubes fall on the central part of the cone tube 4, the operation of the motor 7 will drive the driving rod 10 to rotate, and the driving rod 10 will drive the auger 9 to rotate. When the auger 9 rotates, the crushed ice cubes concentrated in the central part of the cone tube 4 will be transmitted downward; under the action of the auger 9, the crushed ice cubes will eventually be transmitted to the slot 14 on the sealing block 13. As the ice cubes in the slot 14 continue to increase, the auger 9 will compact the ice cubes in the slot 14. When the ice cubes fill the slot 14, the ice cubes will press against the The auger 9 moves upward, and the upward movement of the auger 9 will be detected by the displacement sensor 17, and the displacement sensor 17 will control the cylinder 16 to run one round trip; the cylinder 16 drives the sealing block 13 to move backward, and the sealing block 13 drives the ice cubes in the slot 14 to move backward. When the slot 14 moves to the position overlapping with the slot 2 15, the ice cubes in the slot 14 will automatically fall downward, and then the cylinder 16 will drive the sealing block 13 to reset. During this process, the bottom of the conical tube 4 remains sealed throughout.

[0020] See Figure 3-Figure 4 、 Figure 7-Figure 8 The sealing mechanism includes a sealing cabin 18 fixed to the outside of the conical cylinder 4, the sealing cabin 18 is sealed with the inner wall of the cylinder 3 and a support ring 19 is provided in the sealing cabin 18, the support ring 19 is vertically slidably connected to the sealing cabin 18, and a plurality of springs 20 are connected between the support ring 19 and the sealing cabin 18; a sealing gasket 21 is fixedly connected to the support ring 19, the sealing gasket 21 is narrow at the top and wide at the bottom, and the sealing gasket 21 is sealed with the inner wall of the cylinder 3 and the outer wall of the conical cylinder 4; During operation, an upward elastic force can be applied to the sealing gasket 21 by means of a plurality of springs 20, so that the sealing gasket 21 can fit tightly against the inner wall of the gas cylinder 3 and the outer wall of the conical cylinder 4; since the sealing gasket 21 is narrow at the top and wide at the bottom, when gas enters the gas cylinder 3, the gas pressure in the gas cylinder 3 increases, and the conical cylinder 4 starts to move downward. When the conical cylinder 4 moves downward, it drives the sealing gasket 21 to move downward. Under the action of friction, the sealing gasket 21 will fit more tightly against the outer wall of the conical cylinder 4 and the inner wall of the gas cylinder 3, thereby effectively avoiding the problem of ethane gas leakage in the gas cylinder 3 due to the contraction of the conical cylinder 4 at low temperature and the formation of a gap between the conical cylinder 4 and the inner wall of the gas cylinder 3.

[0021] See Figure 1-2 As a further embodiment of the present invention, the purge mechanism includes two steam engines 22 fixed to the frame 2, and the two steam engines 22 are symmetrically distributed on the left and right sides of the sealing frame 12; a telescopic tube 23 is fixedly connected to the right steam engine 22, and the upper end of the telescopic tube 23 is connected to the upper part of the oil delivery arm 1 through a flange, and the lower part of the oil delivery arm 1 is connected to the gas cylinder 3 through a flange; During operation, a large amount of high-temperature steam can be generated by the steam engine 22 on the right. The high-temperature steam enters the oil transfer arm 1 from the upper part through the telescopic pipe 23, and then begins to purge the residual liquid ethane in the oil transfer arm 1. The liquid ethane is vaporized under the action of the steam and follows the steam from the lower part of the oil transfer arm 1 into the gas cylinder 3.

[0022] See Figure 3 、 Figure 6-Figure 7 A heating frame 24 is provided above the sealing frame 12. The heating frame 24 is fixedly connected to the bottom portion of the conical cylinder 4 and three vent pipes 25 are symmetrically fixedly connected to the left and right sides of the heating frame 24. The other two ends of the three vent pipes 25 are fixedly connected to the steam engine 22 and the sealing cabin 18 respectively. During operation, the sealing gasket 21 will harden under the action of low temperature, thereby reducing the sealing effect of the sealing gasket 21; the left steam engine 22 is started to transport steam through the left three-way vent pipe 25 to the sealed cabin 18 and the heating frame 24 respectively, and the steam in the sealed cabin 18 and the heating frame 24 finally enters the right steam engine 22 through the right three-way vent pipe 25 for secondary heating; When the steam enters the sealed cabin 18, it can heat the sealing gasket 21 to soften it. The softened sealing gasket 21 can better fit with the outer wall of the conical cylinder 4 and the inner wall of the air cylinder 3, thereby improving the sealing effect of the sealing gasket 21. When the steam enters the heating frame 24, it can heat the bottom of the conical tube 4 and the upper part of the sealing frame 12. After heating, the accumulated ice in this part will melt slightly. Since this part is far away from the low-temperature area inside the conical tube 4, the temperature of this part will not be very low. Therefore, the shrinkage degree of the sealing block 13 is relatively low, and the sealing effect will not be very poor. In addition, the melted ice will produce a small amount of water, which will penetrate into the gap between the ice and the sealing block 13 to form a liquid seal effect, thereby effectively ensuring the sealing effect of this part. When the sealing block 13 drives the slot 14 to move to a position overlapping with the slot 2 15, the melted water can promote the falling of the ice in the slot 14.

[0023] See Figure 1-Figure 2 , the bottom of the frame 2 is fixedly connected to two telescopic brackets 26, and the telescopic bracket 26 is elastic; During operation, the elasticity of the telescopic bracket 26 can ensure that the conical cylinder 4 can be located in the upper position inside the cylinder 3. When the air pressure inside the cylinder 3 increases, the telescopic bracket 26 can ensure that the cylinder 3 and the frame 2 can move downward normally.
