Description

Technical Field

[0001] This utility model belongs to the field of fractionation equipment technology, and in particular to a fractionation device for petroleum coke production. Background Technology

[0002] Fractional distillation is a method of separating mixtures with different boiling points; it involves heating a mixture and then cooling and separating the components based on their different boiling points into relatively pure single substances. In the process of fractionating crude oil to produce petroleum tar, condensers are typically used to condense the products, and the heat is converted using the specific heat capacity of water. However, the heat absorbed by the condensate cannot be recycled, resulting in a significant loss of energy and a waste of resources during the fractional distillation process.

[0003] A search revealed, for example (authorization announcement number CN219922096U), a petroleum coke production fractionation device, including a support frame with a support plate on the frame, and a material exchange seat slidably connected to the support plate laterally. This device allows for lateral adjustment of the material exchange seat, moving the pipeline and facilitating feeding or unloading. However, this device cannot recycle the condensate from the petroleum coke production process, causing the heat carried in the condensate to dissipate and disappear, reducing the fractionation efficiency and resource consumption of the device. Utility Model Content

[0004] The purpose of this invention is to provide a petroleum coke production fractionation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a petroleum coke production fractionation device, comprising:

[0006] The bottom plate has a distillation tank for producing stone tar on its top. The top of the distillation tank is connected to the condenser box through a pipe. The bottom of the condenser box is welded to the top plate. The top plate is fixedly connected to the bottom plate by four welded fixing columns.

[0007] The preheating tank is fixed at the bottom and the top of the base plate. The preheating tank is connected to the distillation tank through a pipe. A hollow connecting pipe is connected to one side of the preheating tank, and the other end of the connecting pipe passes through the top plate and connects to the condenser.

[0008] A storage tank for heating raw materials is located inside a preheating barrel. The preheating barrel has a water tank for condensate circulation, and the side wall of the preheating barrel is also equipped with an interface with a valve.

[0009] As a preferred embodiment, a drive motor that provides power is screwed to the bottom of the base plate, the output shaft of the drive motor is connected to a connecting shaft, and the connecting shaft is rotatably connected to the base plate.

[0010] As a preferred embodiment, the output shaft of the drive motor is connected to one end of the rotating shaft via a connecting shaft, and the other end of the rotating shaft is rotatably connected to the inner top wall of the distillation tank.

[0011] As a preferred embodiment, bushings are fixed at both ends of the rotating shaft, and C-shaped scrapers are symmetrically welded on both sides of the bushings. The inner wall of the scrapers is rotatably connected to a blade that agitates the water flow.

[0012] As a preferred embodiment, several evenly arranged L-shaped stirring blades are symmetrically welded to the outer wall of the rotating shaft.

[0013] As a preferred embodiment, the condenser box has a fixed plate welded inside to facilitate the condensation of distilled gas. The fixed plate has a through groove in the middle, and the inner wall of the groove is equally divided with multiple condenser tubes for condensing stone tar.

[0014] As a preferred embodiment, the top of the condenser box is provided with a condensate filling port, and one end of the condenser pipe passes through the condenser box and is connected to the pipeline.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0016] This petroleum coke production fractionation unit has a preheating tank fixed to the top of the bottom plate. After the petroleum coke fractionation production in the distillation tank is completed, crude oil is usually directly added into the distillation tank. The crude oil at room temperature will cause the temperature inside the distillation tank to drop rapidly. The preheating tank allows the condensate from the production of petroleum coke to be connected into the preheating tank. The temperature and water volume of the preheating tank are controlled through a set interface. A storage tank is also set inside the preheating tank, which is connected to a water tank inside the preheating tank. This allows the crude oil inside the storage tank to be heated through heat conduction, enabling the distillation tank to start production more quickly when crude oil is added. It also recycles water and heat resources, reduces energy consumption, and improves the petroleum coke fractionation production efficiency of the unit.

[0017] This petroleum coke production fractionation unit has a drive motor connected to the bottom of the base plate by screws. The output shaft of the drive motor is connected to a rotating shaft via a connecting shaft. The rotating shaft is rotatably connected to the inner wall of the distillation tank. Scrapers and stirring paddles are connected to the side walls of the rotating shaft, and blades are rotatably connected inside the scrapers. Thus, the drive motor drives the rotating shaft to rotate inside the distillation tank, making the crude oil inside the distillation tank more evenly heated, thereby making the fractionation production of petroleum coke more thorough and increasing the output of petroleum coke production.

[0018] This device solves the problem that existing equipment cannot utilize the heat carried by the water used for condensation, thus avoiding energy loss and improving the fractionation efficiency of the device. Attached Figure Description

However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0027] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0028] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0029] Example

[0030] like Figures 1 to 4As shown, this application addresses the problem that during the production of petroleum tar, after the condensing water condenses the petroleum tar, it is impossible to utilize the water containing heat, thus preventing the entry of room-temperature crude oil into the distillation tank 4, which would cause a temperature drop and reduce production efficiency.

[0031] This embodiment includes:

[0032] The base plate 1 has four support legs welded to its bottom. These legs not only separate the base plate 1 from the ground but also facilitate the separation of the drive motor 16, which is fixed to the bottom of the base plate 1, from the ground. The top of the base plate 1 is equipped with a distillation tank 4 for producing limestone tar. A rotating shaft 9 is rotatably connected to the inner wall of the distillation tank 4. One end of the rotating shaft 9 passes through the distillation tank 4 and is connected to the output shaft of the drive motor 16 via a connecting shaft. To prevent the high temperature inside the distillation tank 4 from being transferred to the drive motor 16 during production, a water jacket is provided on the outside of the connecting shaft. The water jacket is mainly used to absorb the transferred heat through the water inside it, thereby preventing the high temperature inside the distillation tank 4 from affecting the use of the drive motor 16. Heat dissipation mechanisms are provided on both sides of the fixed part of the drive motor 16. The heat dissipation mechanisms and the connecting shaft protect the drive motor 16 and facilitate its use.

[0033] The top of the distillation tank 4 is connected to the condenser 6 via a pipe. Inside the condenser 6, a fixing plate 13 is fixed. The fixing plate 13 has a through-type groove 14 inside. Multiple evenly distributed condenser pipes 15 are arranged in the groove 14. One end of the condenser pipe 15 passes through the condenser 6 and is connected to the pipe. Together with the filling port 7 set at the top of the condenser 6, the condenser collects the tar gas produced by the fractionation. The bottom of the condenser 6 is welded to the top plate 5. The top plate 5 is fixedly connected to the bottom plate 1 via four welded fixing columns 3. The top plate 5 is connected to the top of the bottom plate 1 via the fixing columns 3, so that the condenser 6 connected to the top of the top plate 5 is structurally stable during use.

[0034] The preheating tank 2 is fixed at the bottom to the top of the base plate 1, and is connected to the distillation tank 4 through a connecting pipe. A hollow connecting pipe 8 is connected to one side of the preheating tank 2, and the other end of the connecting pipe 8 passes through the top plate 5 and is connected to the condenser 6. The preheating tank 2 is designed so that when the tar gas is condensed, the water that has absorbed heat can be transported to the interior of the preheating tank 2, thereby circulating the heat and avoiding direct discharge that would waste resources.

[0035] Storage tank 12 for heating raw materials is located inside preheating tank 2. Preheating tank 2 is equipped with a water tank 10 for condensate circulation. The side wall of preheating tank 2 is also equipped with an interface 11 with a valve. A pump body is installed inside storage tank 12. The pump body can transport the preheated crude oil to the inside of distillation tank 4 through a connected pipe. The interface 11 located on one side of preheating tank 2 can not only control the amount of water inside preheating tank 2, but also control the temperature to avoid overheating and direct vaporization of tar in crude oil.

[0036] The heating of crude oil not only allows for the recycling of heat from the condensed and absorbed water body, but also prevents a rapid drop in the internal temperature of the distillation tank 4 when crude oil is added. This helps reduce energy loss during heating and fractionation, and maintains the efficiency of petroleum tar fractionation production.

[0037] The interior of the distillation tank 4 is equipped with an existing and mature heating structure, which can reasonably and accurately control the temperature inside the distillation tank 4.

[0038] The distillation tank 4 and the drive motor 16 are both conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0039] Working principle

[0040] When using this petroleum coke production fractionation unit, at the initial start-up, crude oil at room temperature is directly added into the distillation tank 4. The drive motor 16 is controlled to rotate, which drives the rotating shaft 9 connected by the connecting shaft to rotate inside the distillation tank 4. This drives the connected stirring paddle 19, scraper 17 and blade 18 to rotate. The distillation tank 4 is connected to the condenser 6 through the connecting pipe. The condenser 6 is equipped with a condenser pipe 15. One end of the condenser pipe 15 is connected to the pipe. Condensate is added into the condenser 6 through the filling port 7 at the top of the condenser 6.

[0041] After the condensation of petroleum tar is completed, the condensate containing heat is transported to the interior of the preheating tank 2 through the connecting pipe 8. The temperature and water volume inside the preheating tank 2 are controlled through the interface 11. Room temperature crude oil is put into the storage tank 12 inside the preheating tank 2 through the inlet pipe at the top of the preheating tank 2 to complete the preheating of the crude oil, so that it can be recycled.
