Description

Technical Field

[0001] The utility model relates to the technical field of condensing devices, in particular to a condensing device for naphtha processing. Background Art

[0002] Naphtha is one of the petroleum products, also known as chemical light oil or crude gasoline. It is a light oil used as a chemical raw material produced by processing crude oil or other raw materials. It is mainly used as a chemical raw material. Due to different uses, there are various distillation ranges. China stipulates that the distillation range is around 220°C as the final distillation point. When used as a cracking raw material for the production of ethylene, the 70°C to 145°C fraction is used, which is called light naphtha. When the purpose is to produce aromatics or high-octane gasoline, the 70°C to 180°C fraction is used, which is called heavy naphtha. When used as a solvent, it is called solvent naphtha. Aromatic solvents from coal tar are also called heavy naphtha or solvent naphtha. At the same time, a condensing device is needed to cool the naphtha distillate gas during the refining process.

[0003] In the prior art, a condenser for naphtha processing, such as that disclosed in Chinese patent number CN208843995U, includes a condenser shell, the top of which is fixedly connected to an air inlet pipe, the bottom of which passes through the condenser shell and extends to the interior thereof, and is fixedly connected to a spiral condenser pipe, the end of the spiral condenser pipe away from the air inlet pipe is fixedly connected to a liquid outlet pipe, the bottom of which passes through the condenser shell and extends to the exterior thereof. The utility model makes the condenser for naphtha processing more efficiently cooled by the condenser shell, the air inlet pipe, the spiral condenser pipe, the liquid outlet pipe, the cooling shell, the ice outlet, the first water pump, the first water outlet pipe, the water tank, the second pump water pipe, the second water pump, the second pump water pipe, and the second water outlet pipe mutually cooperating. The cooling shell always maintains a low temperature for the circulating water and the condenser shell, thereby more efficiently condensing the naphtha processing gas, achieving an ideal cooling effect and accelerating the working process of naphtha processing.

[0004] While the aforementioned patent is capable of condensing gas, some issues remain. While water can circulate within the condensing shell, the water flow may be slow, resulting in higher water temperatures near the spiral condenser tubes and significantly reducing the heat exchange efficiency of the spiral condenser tubes. When high-temperature gas continues to flow through the spiral condenser tubes, it cannot be fully cooled in a timely manner. Therefore, the present invention provides a condensing device for naphtha processing. Utility Model Content

[0005] To address the shortcomings of existing technologies, the present invention provides a condensing device for naphtha processing that addresses the potential for slow water flow, which can lead to higher water temperatures near the spiral condenser tubes and significantly reduce the heat exchange efficiency of the spiral condenser tubes. This also addresses the problem of high-temperature gas not being adequately cooled in a timely manner when continuously flowing through the spiral condenser tubes.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A condensing device for naphtha processing, comprising a condensing component, wherein the outer wall of the condensing component is provided with a circulating cooling component;

[0014] Beneficial effects

[0015] The utility model provides a condensing device for naphtha processing. Compared with the prior art, it has the following beneficial effects:

[0016] (1) The condensing device for naphtha processing, when condensing naphtha gas, first introduces cooling water into the first cooling shell, and then introduces the gas into the spiral condenser tube. The gas in the spiral condenser tube will condense into liquid when it is cooled. At the same time, in order to prevent the water flow temperature near the spiral condenser tube from being too high, the motor can be turned on, and the motor drives the rotating rod to rotate slowly, and the rotating rod drives the first stirring plate to rotate. The first stirring plate can stir the water flow inside the spiral condenser tube. At the same time, when the rotating rod rotates, it will drive the first gear to rotate, and the first gear will then drive the second gear to rotate. The second gear can also drive the inner ring gear to rotate. When the inner ring gear rotates, it drives the two second stirring plates to stir the outside of the spiral condenser tube. The mutual stirring of the two makes the water in the first cooling shell in a dynamic flow state, avoiding the local overheating of the water near the spiral condenser tube, thereby improving the condensation efficiency of the naphtha gas.

[0017] (2) The condensing device for naphtha processing can add cooling water to the second cooling shell when the spiral condenser is condensing. The cooling water in the second cooling shell can absorb the heat on the surface of the first cooling shell, thereby reducing the temperature in the first cooling shell. Ice cubes are put into the second cooling shell through the ice trough, and then into the ice box, thereby reducing the water temperature in the second cooling shell and improving the cooling effect on the first cooling shell. Then the water pump can be turned on, and the water pump passes the ice water in the ice box into the first cooling shell through the first delivery pipe and the second delivery pipe. Since there are ice cubes in the ice box, the water temperature passed into the first cooling shell is lower, thereby improving the condensation effect on the spiral condenser. Then the water in the first cooling shell is discharged from the first cooling shell through the outlet pipe, completing the water flow circulation of the first cooling shell and further improving the condensation effect on the spiral condenser.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] This utility model provides two technical solutions:

[0026] Figure 1-Figure 5 A first embodiment is shown: a condensing device for naphtha processing, comprising a condensing component 1, the outer wall of the condensing component 1 being provided with a circulating cooling component 2;

[0027] The condensing assembly 1 includes a first cooling shell 11, a top cover 12 is fixedly mounted on the top of the first cooling shell 11, a motor 13 is fixedly mounted on the top of the top cover 12, the output end of the motor 13 passes through the top of the top cover 12 and is fixedly connected to a rotating rod 14, a rotating ring 16 is rotatably mounted on the bottom end of the top cover 12, an inner gear ring 17 is fixedly mounted on the top end of the rotating ring 16, the rotating ring 16 enables the inner gear ring 17 to rotate, two second stirring plates 110 are fixedly mounted on the bottom end of the inner gear ring 17, and a first gear 18 is fixedly sleeved on the outer wall of the rotating rod 14;

[0028] The circulating cooling assembly 2 includes a second cooling shell 21 , which is fixedly connected to the first cooling shell 11 .

[0029] A second gear 19 is rotatably mounted on the bottom end of the top cover 12. The second gear 19 is meshed with the first gear 18. The second gear 19 is meshed with the inner ring gear 17. A group of first stirring plates 15 are fixedly mounted on the outer wall of the rotating rod 14. When the first gear 18 rotates, it can drive the second gear 19 to rotate. When the second gear 19 rotates, it can drive the inner ring gear 17 to rotate.

[0030] A spiral condenser 111 is provided inside the first cooling shell 11, one end of the spiral condenser 111 passes through the top of the top cover 12, and the other end of the spiral condenser 111 passes through the bottom end of the inner wall of the first cooling shell 11. The outer wall of the first cooling shell 11 is fixedly connected to a water outlet pipe 113. The water in the first cooling shell 11 can be discharged through the water outlet pipe 113 and discharged into the second cooling shell 21.

[0031] Figure 1-Figure 5 A second embodiment is shown, which mainly differs from the first embodiment in that: a group of ice chutes 22 are opened through the top of the second cooling shell 21, which can evenly drop ice cubes into the second cooling shell 21; an ice box 23 is fixedly installed on the outer wall of the second cooling shell 21, and ice cubes can be placed in the ice box 23; a through groove 25 is opened through the inner wall of the ice box 23, and the through groove 25 extends to the inner wall of the second cooling shell 21, so that the ice box 23 and the second cooling shell 21 can be connected to each other.

[0032] A water pump 27 is fixedly installed at the bottom end of the first cooling shell 11. The input end of the water pump 27 is fixedly connected to the first delivery pipe 26, and the first delivery pipe 26 is fixedly connected to the ice box 23. The output end of the water pump 27 is fixedly connected to the second delivery pipe 28, and the second delivery pipe 28 is fixedly connected to the first cooling shell 11. The water pump 27 passes the ice water in the ice box 23 into the interior of the first cooling shell 11 through the first delivery pipe 26 and the second delivery pipe 28.

[0033] A filter plate 24 is fixedly installed on the inner wall of the ice box 23, and a drain valve 29 is provided at the bottom end of the second cooling shell 21. The filter plate 24 can prevent the first delivery pipe 26 from being blocked by ice cubes when extracting ice water. When there is a lot of water in the second cooling shell 21 or the water temperature is high, it can be discharged to the outside through the drain valve 29.

[0034] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0035] During operation, first add cooling water to the second cooling shell 21 and the first cooling shell 11, and then pass the gas into the spiral condenser 111. The gas in the spiral condenser 111 will condense into liquid when it is cooled. At the same time, in order to prevent the water flow near the spiral condenser 111 from being too hot, the motor 13 can be turned on. The motor 13 drives the rotating rod 14 to rotate slowly, and the rotating rod 14 drives the first stirring plate 15 to rotate. The first stirring plate 15 can stir the water flow inside the spiral condenser 111. At the same time, when the rotating rod 14 rotates, it will drive the first gear 18 to rotate, and the first gear 18 will then drive the second gear 19 to rotate, and the second gear 19 can drive the inner ring 17 to rotate. When the inner ring 17 rotates, it drives the two second stirring plates 110 to stir on the outside of the spiral condenser 111. The mutual stirring of the two makes the water in the first cooling shell 11 in a dynamic flow state, thereby avoiding local overheating of the water near the spiral condenser 111. The cooling water in the second cooling shell 21 can absorb the heat from the surface of the first cooling shell 11, thereby reducing the temperature in the first cooling shell 11. Ice cubes are added to the second cooling shell 21 through the ice chute 22, and then to the ice box 23, thereby reducing the water temperature in the second cooling shell 21 and improving the cooling effect on the first cooling shell 11. The water pump 27 can then be turned on. The water pump 27 passes the ice water in the ice box 23 into the interior of the first cooling shell 11 through the first delivery pipe 26 and the second delivery pipe 28. Since there are ice cubes in the ice box 23, the water temperature entering the first cooling shell 11 is relatively low, thereby improving the condensation effect on the spiral condenser 111. The water in the first cooling shell 11 is then discharged from the interior of the first cooling shell 11 through the water outlet pipe 113, completing the water circulation of the first cooling shell 11 and further improving the condensation effect on the spiral condenser 111.
