Description

Technical Field

[0001] The utility model relates to the technical field of gas-liquid separation equipment, in particular to a gas-liquid separation equipment for petroleum refining. Background Art

[0002] Petroleum is an important and non-renewable fossil energy source, which plays an irreplaceable role in the manufacturing industry. In order to ensure that petroleum can be used in different fields, it needs to be refined. An important link in petroleum refining is gas-liquid separation. A large amount of raw gas and reaction gas produced in the process of petroleum refining will carry some mist and petroleum droplets. In order to protect the compressor in the subsequent production process from damage, the gas needs to be purified to ensure that the droplet content in the gas is minimized. This step requires the use of gas-liquid separation equipment.

[0003] In order to improve the gas-liquid separation efficiency during oil refining, the prior art has made many improvements to oil refining gas-liquid separation equipment. For example, the patent with patent publication number CN220090570U discloses an oil refining gas-liquid separation equipment, including a tank body, the bottom of the tank body is fixedly connected to an oil outlet pipeline, the bottom of the oil outlet pipeline is fixedly connected to an oil outlet valve, the left side of the tank body is fixedly connected to a liquid inlet pipe, the inner top of the tank body is fixedly connected to a partition, the bottom of the partition is fixedly connected to a guide plate, the inner top of the tank body is fixedly connected to a motor, the output end of the motor is fixedly connected to a rotating shaft, and the surface of the rotating shaft is fixedly connected to blades; the top of the tank body is fixedly connected to an air outlet, the upper part of the air outlet is fixedly connected to an air outlet valve, and the top of the air outlet valve is fixedly connected to an exhaust pipe.

[0004] The above patent has obvious beneficial effects, but still has the following shortcomings in actual operation:

[0005] In the above-mentioned comparative documents, the oil is broken up by high-speed rotating blades to improve the efficiency of gas and liquid separation. However, due to the certain viscosity of oil, when the oil enters the tank body through the liquid inlet pipe, the weight of the oil stuck together is heavy, and the oil will fall down rapidly after entering the tank body. When the oil enters the bottom of the tank body, it cannot be broken up and dispersed. Therefore, the efficiency of breaking up the oil by blades in the above-mentioned comparative documents is low. Therefore, the field urgently needs to improve the oil refining gas-liquid separation equipment to solve the defects of the existing technology. Utility Model Content

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] See also Figure 1-Figure 5 A petroleum refining gas-liquid separation device comprises a tank body 1, a liquid inlet 2 is arranged on the side of the tank body 1, a liquid discharge port 3 is arranged at the lower end of the tank body 1, an exhaust port 4 is arranged at the upper end of the tank body 1, a driving motor 5 is arranged at the upper end of the tank body 1, a partition plate 6 is fixedly installed in the tank body 1, a plurality of through holes are penetrated through the partition plate 6, the partition plate 6 divides the inside of the tank body 1 into a storage chamber 7 and a crushing chamber 8, a connecting rod 9 extending to the inside of the tank body 1 is fixedly installed at the output end of the driving motor 5, a hollow rod 10 extending to the bottom of the tank body 1 is fixedly installed at the lower end of the connecting rod 9, a plurality of blades 11 are fixedly installed on the side of the hollow rod 10, a rotating rod 12 penetrating the hollow rod 10 is fixedly installed at the lower end of the connecting rod 9, and a feeding auger 13 is arranged on the side of the rotating rod 12.

[0029] The oil is pumped into the tank body 1 through the liquid inlet 2. The number of the liquid inlet 2 is not limited here, and can be one or more than one. The drive motor 5 is started, and the output end of the drive motor 5 drives the connecting rod 9 to rotate. The connecting rod 9 drives the hollow rod 10 and the rotating rod 12 to rotate. The hollow rod 10 drives a plurality of blades 11 to rotate. The rotating rod 12 drives the feeding auger 13 to rotate. After the oil enters the tank body 1 through the liquid inlet 2, it falls freely into the crushing chamber 8. Due to the obstruction of the partition plate 6, the oil will not fall into the storage chamber 7 quickly. Through the blades 1 1 The oil is crushed, and the gas contained in the oil rises after crushing. The oil falls into the storage chamber 7 through the through hole on the partition plate 6, and then is transported to the upper part of the crushing chamber 8 by the feeding auger 13 and falls into the crushing chamber 8 again for secondary crushing. The gas is discharged through the exhaust port 4. When there is a lot of oil liquid in the storage chamber 7, it is discharged through the drain port 3. The speed of the oil falling into the storage chamber 7 is reduced by the partition plate 6, so as to improve the effect of crushing the oil. At the same time, the oil in the storage chamber 7 is transported to the crushing chamber 8 for secondary crushing, so as to improve the effect of gas-liquid separation.

[0030] Among them, the above-mentioned drive motor 5 can be purchased on the market. It is a mature technology and has been fully disclosed, so it is not repeated in the specification. The drive motor 5 is equipped with a power connection line, and it is electrically connected to the external main controller and 220V phase voltage (or 380V line voltage) through the power line, and the main controller can be a conventional known device such as a computer that plays a control role.

[0031] See also Figure 2-Figure 5 A first condensation plate 14 is fixedly mounted on the upper side wall of the tank body 1 . A plurality of through holes are formed through the first condensation plate 14 . The connecting rod 9 passes through the first condensation plate 14 .

[0032] The petroleum vapor contained in the gas is condensed by the first condensation plate 14, and the condensed petroleum vapor drips into the grinding chamber 8, thereby reducing the petroleum component contained in the gas and improving the gas-liquid separation effect.

[0033] See also Figure 2 , Figure 3 and Figure 4 A second condensation plate 16 is fixedly mounted on the upper side wall of the tank body 1 , and a through hole is formed through the second condensation plate 16 . The through hole on the second condensation plate 16 and the through hole on the first condensation plate 14 are staggered.

[0034] Since the area of ​​the first condensation plate 14 is limited and the through holes on the first condensation plate 14 and the second condensation plate 16 are staggered, when the gas continues to rise through the through holes on the first condensation plate 14, the gas will contact the second condensation plate 16. The second condensation plate 16 will again condense the petroleum vapor contained in the gas, further reducing the petroleum component contained in the gas and further improving the gas-liquid separation effect.

[0035] See also Figure 5 A plurality of mounting rods 17 are fixedly installed on the side of the lower end of the connecting rod 9. The lower end of the mounting rod 17 is fixedly installed with the upper end of the hollow rod 10. The upper end of the feeding auger 13 exceeds the upper end of the hollow rod 10. The mounting rod 17 is used for connecting the connecting rod 9 and the hollow rod 10 by means of fasteners, etc., so as to facilitate installation or disassembly and maintenance thereof.

[0036] Please refer to the figure Figure 2 , Figure 3 and Figure 4 A plurality of first cleaning rods 18 are provided in the storage chamber 7, and the ends thereof are fixedly mounted on the side of the hollow rod 10. The side of the first cleaning rod 18 is in contact with the inner wall and the bottom of the tank body 1, and the end of the blade 11 away from the hollow rod 10 is fixedly mounted on the side of the first cleaning rod 18.

[0037] When the hollow rod 10 rotates, the first cleaning rod 18 rotates accordingly, and the first cleaning rod 18 scrapes off the oil adhering to the inner wall and bottom of the tank body 1 to prevent a large amount of oil liquid from adhering to the inner wall and bottom of the tank body 1. At the same time, the first cleaning rod 18 improves the connection strength of the blade 11 and extends the service life of the blade 11.

[0038] Please refer to the figure Figure 2 , Figure 3 and Figure 4 A plurality of second cleaning rods 19 are provided in the crushing chamber 8, and the ends thereof are fixedly mounted on the side of the hollow rod 10. The side of the second cleaning rod 19 is in contact with the inner wall of the tank body 1, the upper surface of the partition plate 6 and the lower surface of the first condensation plate 14. The end of the blade 11 away from the hollow rod 10 is fixedly mounted on the side of the second cleaning rod 19.

[0039] The second cleaning rod 19 rotates with the hollow rod 10 and scrapes off the petroleum liquid adhering to the inner wall of the tank body 1 and the upper surface of the partition plate 6. At the same time, as the first condensation plate 14 condenses, the petroleum gas condenses into water droplets. When the water droplets are larger, they will drip into the crushing chamber 8. This process takes a certain amount of time, thus reducing the condensation effect of the first condensation plate 14. The second cleaning rod 19 scrapes off the droplets that have not yet condensed and saturated on the lower surface of the first condensation plate 14. At this time, the lower surface of the first condensation plate 14 can condense again, accelerating the dripping speed of the condensed liquid droplets, thereby accelerating the condensation effect.

[0040] See also Figure 3 , Figure 4 and Figure 5 A scraper rod 20 is fixedly installed on the side of the connecting rod 9, and the side of the scraper rod 20 is in contact with the inner wall of the tank body 1 and the lower surface of the second condensation plate 16. A plurality of exhaust fan blades 21 are fixedly installed on the side of the connecting rod 9, and the exhaust fan blades 21 blow the internal gas of the tank body 1 toward the exhaust port 4.

[0041] When the scraper rod 20 rotates, it scrapes off the liquid droplets that have not yet condensed and saturated the lower surface of the second condensation plate 16, thereby improving the effect of gas condensation. At the same time, the exhaust fan blades 21 accelerate the gas to blow toward the exhaust port 4, generating an upward negative pressure on the gas, thereby improving gas fluidity and accelerating the efficiency of gas-liquid separation.

[0042] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
