Description

Technical Field

[0001] This utility model relates to the field of coking equipment technology, and more specifically, to a device for preventing coke blockage in the feed pipeline of a coker. Background Technology

[0002] The coke tower is a key piece of equipment in a petrochemical delayed coking unit, primarily used to convert heavy residue oil into light oil products and coke. The coke tower's structure consists of: Tower body: typically a tall, vertical cylindrical structure welded from steel plates. The tower body must withstand high temperatures, high pressures, and coke abrasion, therefore it is made of high-temperature, high-pressure, and corrosion-resistant alloy steel or carbon steel; Tower top: equipped with an oil / gas outlet connected to the fractionation system, allowing the reacted oil / gas to enter subsequent processing units. It is also equipped with safety valves, pressure gauges, and other safety and measuring instruments to ensure equipment safety. The entire system monitors operating parameters. At the bottom of the coking tower, there is a feed inlet through which high-temperature residual oil enters the coking tower. A coke discharge outlet is also located at the bottom to remove coke during decoking. During operation, the reaction products in the coking tower include gaseous oil and gas and solid coke. Due to gravity and space, the oil and gas flow upwards and are discharged from the top of the tower, while the coke adheres to the tower walls and internal components, gradually accumulating. As the reaction continues, the coke layer thickens. Since the coke accumulates at the bottom of the tower after formation, while the feed inlet is located within the tower body, it is necessary to implement coke anti-clogging measures at the feed inlet.

[0003] In related technologies, during the use of coke towers, hydraulic decoking is generally used to remove coke from the tower body under high pressure, and the coke is discharged from the tower body through the discharge port for use.

[0004] However, in the current use of coke towers, when hydraulic decoking is performed, high-pressure water is sprayed around the inner wall of the tower. Since the feed inlet is located at the bottom of the tower, the high-pressure water spray can easily push coke into the feed inlet, making it difficult to prevent coke blockage at the feed inlet. This results in blockage at the feed inlet during subsequent feeding, affecting the feeding smoothness and anti-blockage effect. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Reference Figures 1-4 This utility model provides a technical solution: a device for preventing coke blockage in the feed pipeline of a coker, including a conical lower end cap 1 and a feed anti-blocking mechanism. A feed inlet 2 is installed on the left side of the conical lower end cap 1, and a coke outlet 3 is installed at the bottom of the conical lower end cap 1. A hollow anti-blocking medium can be formed at the connection between the feed inlet 2 and the conical lower end cap 1 to perform coke hollowing and blocking work at the connection between the feed inlet 2 and the conical lower end cap 1, preventing coke from entering the interior of the feed inlet 2, which would be difficult to remove in subsequent hydraulic decoking, leading to blockage of the feed inlet 2. Therefore, the feeding smoothness and anti-blocking effect of the feed inlet 2 are improved.

[0031] Reference Figures 1-4 In a preferred embodiment, the feed anti-blocking mechanism includes an anti-blocking seat 4, which is movably connected to the left side of the inner wall of the conical lower head 1. The anti-blocking seat 4 has an anti-blocking cavity 5 communicating with the feed inlet 2. An anti-blocking opening 6 is located on the right side of the inner wall of the anti-blocking cavity 5, and an anti-blocking mesh 7 is movably connected inside the anti-blocking opening 6. An anti-blocking support mechanism is fixedly connected to the bottom of the inner wall of the anti-blocking cavity 5. The anti-blocking seat 4 facilitates feed communication between the feed inlet 2 and the conical lower head 1 through the anti-blocking cavity 5. The anti-blocking opening 6, in conjunction with the anti-blocking mesh 7, forms a perforated anti-blocking medium at the connection between the feed inlet 2 and the conical lower head 1, ensuring smooth feed flow through the feed inlet 2. Meanwhile, to prevent coke from entering the feed inlet 2 and to facilitate subsequent hydraulic decoking, the anti-blocking support mechanism includes a support frame 8, a support groove 9, and a support plate 10. The support frame 8 is fixedly connected to the bottom of the inner wall of the anti-blocking cavity 5. The support groove 9 is opened on the left side of the top of the inner wall of the anti-blocking cavity 5. The support plate 10 is movably connected to the bottom of the support groove 9, which can provide a medium for the anti-blocking seat 4 to connect and support the feed inlet 2, so that the anti-blocking seat 4 can be stably supported at the connection between the feed inlet 2 and the lower conical head 1. This avoids the situation where the anti-blocking seat 4 is difficult to support stably at the feed inlet 2 during use, thus improving the support stability and convenience of the anti-blocking seat 4.

[0032] Reference Figures 2-3In a preferred embodiment, a connection port 11 is provided at the top of the inner wall of the support groove 9, and a connecting post 12 is movably connected inside the connection port 11. The bottom of the connecting post 12 is fixedly connected to the top of the support plate 10, which can prevent the support plate 10 and the anti-blocking seat 4 from shifting during use, thus improving the stability of the support plate 10. A stabilizing groove 13 is provided at the bottom of the right side of the inner wall of the support groove 9, and a stabilizing seat 14 is movably connected to the bottom of the stabilizing groove 13. The left side of the top of the stabilizing seat 14 is fixedly connected to the bottom of the support plate 10, which can stabilize the connection between the stud 16 and the support plate 10, thus improving the connection stability between the stud 16 and the support plate 10.

[0033] Reference Figures 2-4 In a preferred embodiment, a screw hole 15 is provided on the top of the stabilizer 14, and a stud 16 is threaded inside the screw hole 15. The stabilizer 14 can provide a medium for the user to raise and lower the support plate 10, thus improving the flexibility of the support plate 10. A reinforcing frame 17 is fixedly connected to the inner wall of the anti-blocking cavity 5. The top of the reinforcing frame 17 is connected to the bottom of the stud 16, which can provide support and reinforcement between the stud 16 and the anti-blocking seat 4, thus improving the working stability of the stud 16.

[0034] Reference Figures 2-4 In a preferred embodiment, a connecting groove 18 is provided on the top of the reinforcing frame 17, and a connecting seat 19 is movably connected inside the connecting groove 18. The top of the connecting seat 19 is fixedly connected to the bottom of the stud 16, which allows for a rotatable connection between the stud 16 and the reinforcing frame 17, thus improving the connection effect between the stud 16 and the reinforcing frame 17. A rotating opening 20 is provided on the top of the inner wall of the stabilizing groove 13, and a rotating shaft 21 is movably connected inside the rotating opening 20. The bottom of the rotating shaft 21 is fixedly connected to the top of the stud 16, which provides a medium for the user to rotate the stud 16, thus improving the ease of operation of the stud 16.

[0035] Specifically, the working process or principle of this device for preventing coke blockage in the feed line of a coker is as follows: During use, the anti-blocking seat 4 is moved by hand to the inside of the lower conical head 1, and the anti-blocking seat 4 drives the support frame 8 into the feed inlet 2. The anti-blocking seat 4 is then moved towards the feed inlet 2. At this time, the support frame 8 follows the anti-blocking seat 4 within the feed inlet 2, guiding the movement between the anti-blocking seat 4 and the feed inlet 2, causing the anti-blocking seat 4 to align the anti-blocking cavity 5 with the feed inlet 2. Simultaneously, the support plate 10 follows the anti-blocking seat 4 into the feed inlet 2, preparing for subsequent support and stabilization between the anti-blocking seat 4 and the feed inlet 2, in conjunction with the support frame 8. Subsequently, the stud 16 is rotated via the rotating shaft 21 and the rotating port 20, causing the stud 16 to engage with the screw hole 15 through the stabilizing seat 14, applying upward pressure to the support plate 10. The moving thread thrust, during this process, the connecting seat 19 follows the stud 16 and rotates inside the connecting groove 18, cooperating with the reinforcing frame 17 to support and stabilize the stud 16 and the anti-blocking seat 4. At the same time, the connecting column 12 follows the support plate 10 and moves inside the connecting port 11, connecting and preventing deviation between the support plate 10 and the anti-blocking seat 4, ensuring that the stud 16, cooperating with the screw hole 15, stably drives the support plate 10 to move upward through the stabilizing seat 14, so that the top of the support plate 10 contacts and abuts against the top of the inner wall of the feed port 2, causing the support plate 10, cooperating with the support frame 8, to support and stabilize the anti-blocking seat 4 and the feed port 2, so that the anti-blocking seat 4, cooperating with the anti-blocking cavity 5 and the anti-blocking mesh 7, forms a hollow anti-blocking medium at the connection between the feed port 2 and the conical lower end cap 1, preventing coke from entering the feed port 2 and causing blockage.

[0036] It should be noted that the conical lower end cap 1, the feed port 2 and the coke outlet 3 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
