Description

Technical Field

[0001] This utility model relates to the field of petroleum distillation technology, and in particular to a distillation tank for petrochemical applications. Background Technology

[0002] Distillation tanks are used in petroleum processing to separate different oil and gas components. During distillation, coke easily forms on the inner wall of the tank, and solid impurities from the petroleum also adhere to the inner wall, reducing heating efficiency and significantly increasing energy consumption. Existing distillation tanks lack the ability to clean these impurities, making them inconvenient to use. Therefore, there is an urgent need to develop a petrochemical distillation tank that is easy to clean and energy-efficient, overcoming current shortcomings and meeting current needs. Utility Model Content

[0003] The purpose of this invention is to provide a distillation tank for petrochemical applications to solve the problems mentioned in the background section.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A petrochemical distillation tank includes a tank body, a drain pipe, an outlet pipe, a cleaning pipe, a scraper, self-closing nozzles, a rotating mechanism, and a high-pressure pump. The tank body contains a heating chamber and a distillation chamber. A drain pipe connected to the distillation chamber is installed on the lower right side of the tank body. An end cap is detachably connected to the drain pipe via threads. The cleaning pipe is rotatably connected to the tank body. The scraper is fixed to the cleaning pipe and fits against the inner wall of the tank body. Multiple self-closing nozzles are installed on the cleaning pipe. The high-pressure pump is fixed to... At the top of the tank, a water supply pipe is fixedly connected to the outlet of the high-pressure pump. The upper end of the cleaning pipe is inserted into the water supply pipe and rotatably connected to it. A rotating mechanism for driving the cleaning pipe to rotate is installed at the top of the tank. The self-closing nozzle includes: a nozzle, a plug, a connecting rod, a spring, and a base plate. The nozzle is fixed and connected to the cleaning pipe. The plug is slidably installed at the front end of the nozzle. Two connecting rods are fixed to the rear side of the plug. Each connecting rod is elastically connected to the base plate through a spring. The base plate is fixed inside the nozzle.

[0005] Preferably, a feed inlet connected to the distillation chamber is installed on the upper left side of the tank body, and a plug is detachably connected to the feed inlet by means of threads.

[0006] Preferably, an output pipe connected to the distillation chamber is installed on the upper right side of the tank.

[0007] Preferably, the rotating mechanism includes a drive motor, a first gear, and a second gear. The drive motor is fixed to the top of the tank. The first gear is fixed on the output shaft of the drive motor. A second gear is provided on one side of the first gear to mesh with it. The second gear is fixed to the cleaning tube.

[0008] The beneficial effects of this utility model are as follows: When using this petrochemical distillation tank, petroleum is added to the distillation chamber for distillation. The high-temperature oil vapor generated during distillation is output from the output pipe. At this time, under the action of spring force, the plug blocks the outlet of the nozzle, preventing petroleum in the distillation chamber from entering the nozzle. After distillation, a high-pressure pump delivers high-pressure water to the nozzle. Under the action of the high-pressure water flow, the plug is pushed outward, allowing the high-pressure water to spray out from the nozzle outlet. In addition, since the plug is still located in front of the nozzle outlet after being pushed out, the sprayed water will impact the plug and splash around, thereby expanding the spray range of the water flow. The water flow cleans the impurities attached to the inner wall of the tank. At the same time, the drive motor drives the first gear and the second gear to rotate. The second gear drives the cleaning pipe to rotate, which in turn drives the scraper and the self-closing nozzle to rotate. The scraper cleans the impurities attached to the inner wall of the tank. The end cap is removed, allowing the impurities to be discharged from the drain pipe with the water flow. In summary, this invention facilitates the cleaning of impurities adhering to the inner wall of the tank and reduces energy consumption. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0015] Specific implementation examples are given below.

[0016] See Figures 1-4 In this embodiment of the present invention, a petrochemical distillation tank includes a tank body 1, a drain pipe 3, an output pipe 4, a cleaning pipe 5, a scraper 6, a self-closing nozzle 7, a rotating mechanism 8, and a high-pressure pump 9. The tank body 1 contains a heating chamber 101 and a distillation chamber 102. The heating chamber 101 is supplied with heat from an external heating furnace, and the distillation chamber 102 is used to store petroleum. An inlet 2 connected to the distillation chamber 102 is installed on the upper left of the tank body 1, and a plug 201 is detachably connected to the inlet 2 via a thread. A drain pipe 3 connected to the distillation chamber 102 is installed on the lower right of the tank body 1, and an end cap 301 is detachably connected to the drain pipe 3 via a thread. An output pipe 4 connected to the distillation chamber 102 is installed on the upper right of the tank body 1. The generated high-temperature oil and gas are output from the output pipe 4. The cleaning pipe 5 is rotatably connected to the tank 1. A sealing ring is provided at the connection between the cleaning pipe 5 and the tank 1, and the sealing ring is located on the outside of the tank 1 to prevent leakage. The scraper 6 is fixed to the cleaning pipe 5 and fits against the inner wall of the tank 1. Multiple self-closing nozzles 7 are installed on the cleaning pipe 5. The high-pressure pump 9 is fixed to the top of the tank 1 and is connected to an external tap water source through a pipeline. A water supply pipe 10 is fixedly connected to the outlet of the high-pressure pump 9. The upper end of the cleaning pipe 5 is inserted into the water supply pipe 10 and rotatably connected to it. A sealing ring is provided at the connection between the cleaning pipe 5 and the water supply pipe 10 to prevent water leakage. A rotating mechanism 8 for driving the cleaning pipe 5 to rotate is installed on the top of the tank 1.

[0017] The rotating mechanism 8 includes a drive motor 801, a first gear 802, and a second gear 803. The drive motor 801 is fixed to the top of the tank 1. The first gear 802 is fixed on the output shaft of the drive motor 801. A second gear 803 is provided on one side of the first gear 802 and meshes with it. The second gear 803 is fixed on the cleaning tube 5. In use, the drive motor 801 drives the first gear 802 and the second gear 803 to rotate, the second gear 803 drives the cleaning tube 5 to rotate, and the cleaning tube 5 drives the scraper 6 and the self-closing nozzle 7 to rotate.

[0018] The self-closing nozzle 7 includes: a nozzle 701, a plug 702, a connecting rod 703, a spring 704, and a base plate 705. The nozzle 701 is fixed and connected to the cleaning tube 5. The plug 702 is slidably installed at the front end of the nozzle 701 and is used to block the outlet of the nozzle 701. Two connecting rods 703 are fixed to the rear side of the plug 702. Each connecting rod 703 is elastically connected to the base plate 705 through the spring 704. The base plate 705 is fixed inside the nozzle 701. When there is no water flow, the plug 702 blocks the outlet of the nozzle 701 under the elastic force of the spring 704.

[0019] Working principle: In operation, this petrochemical distillation tank adds petroleum to the distillation chamber 102 for distillation. The high-temperature oil vapor produced during distillation is output from the output pipe 4. At this time, under the elastic force of the spring 704, the plug 702 blocks the outlet of the nozzle 701, preventing petroleum from entering the nozzle 701 from the distillation chamber 102. After distillation, high-pressure water is pumped to the nozzle 701 by the high-pressure pump 9. The high-pressure water pushes the plug 702 outward, causing the high-pressure water to spray out from the outlet of the nozzle 701. Furthermore, because the plug 702 is pushed out... Located in front of the nozzle 701 outlet, the sprayed water will impact the plug 702 and splash outwards, thereby expanding the spray range of the water flow. The water flow cleans the impurities attached to the inner wall of the tank 1. At the same time, the drive motor 801 drives the first gear 802 and the second gear 803 to rotate. The second gear 803 drives the cleaning pipe 5 to rotate. The cleaning pipe 5 drives the scraper 6 and the self-closing nozzle 7 to rotate. The scraper 6 cleans the impurities attached to the inner wall of the tank 1. The end cap 301 is removed, allowing the impurities to be discharged from the drain pipe 3 with the water flow.

[0020] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
