Description

Technical Field

[0001] The utility model relates to the technical field of dry coke quenching production, in particular to a low-loss dry coke quenching production device. Background Art

[0002] CDQ is a technology used to process metallurgical coke. It reduces smoke emissions, improves coke quality and recovers heat by rapidly cooling high-temperature coke.

[0003] In order to solve the problems of excessive coke burning, carbon dissolution reaction, water-gas reaction and so on caused by high air introduction in the circulating gas, nitrogen is used to replace the air introduced into the dry quenching furnace. By introducing nitrogen into the dry quenching device to partially replace the external air as the circulating cooling gas, the combustible gas content is reduced, the coke burning rate is reduced, and the inherent safety level of the dry quenching device is improved. The furnace tubes and anti-wear tiles of the waste heat boiler heat exchanger are optimized, and the waste heat recovery rate is improved.

[0004] When nitrogen is introduced into the dry quenching furnace, it is necessary to connect the nitrogen delivery pipeline with the nitrogen inlet pipeline of the dry quenching furnace. Since the delivery of nitrogen needs to be in a sealed environment, the sealing of the pipeline connection is required to be high, and the pipeline connection and the inside of the dry quenching furnace need to be sealed before the nitrogen is delivered. The existing pipeline detection methods are mostly judged by the reading displayed by the pressure gauge, and the pressure gauge is mainly used to measure the pressure change inside the pipeline to judge the overall sealing condition of the pipeline. It cannot directly reflect the specific condition of the pipeline connection, such as whether there are tiny gaps or cracks, etc. These places may cause gas leakage, but this leakage may not have a significant impact on the overall pressure in the pipeline, so it is easy to be ignored.

Specific implementation mode

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-6 , the present utility model provides a technical solution: a low-loss coke dry quenching production device, including a furnace body 1, a nitrogen filling pipe 2 is arranged on one side of the furnace body 1, the upper end of the nitrogen filling pipe 2 is integrally connected with a pipe one 3, and the pipe one 3 is connected to a pipe two 4 for nitrogen transportation, and the pipe two 4 can inject nitrogen into the furnace body 1.

[0025] In order to detect the sealing performance of the connection part between the pipe one 3 and the pipe two 4, a support plate 5 is arranged on one side of the furnace body 1, an empty groove 12 is opened at the upper end of one end of the support plate 5, and a detection component is rotatably arranged in the empty groove 12, and the detection component sprays soapy water around the connection part of the pipe one 3 and the pipe two 4 for sealing detection.

[0026] Among them, in order to keep the connection part of the pipe one 3 and the pipe two 4 in a state convenient for spraying soapy water, the pipe two 4 passes through the empty groove 12 and is connected to the pipe one 3, and the pipe two 4 is restricted by the hollow pipe at the center of the empty groove 12 to keep the pipe two 4 stable.

[0027] Furthermore, an adjustment groove 6 is provided in a position of the support plate 5 close to the other side, and a pair of moving rods 8 are slidably connected to both ends of the adjustment groove 6. A bidirectional lead screw 7 is rotatably arranged in the adjustment groove 6. The thread directions on the left and right sides of the bidirectional lead screw 7 are opposite with the center as the symmetry axis. The two moving rods 8 are respectively threadedly connected to both ends of the bidirectional lead screw 7. At the same time, arc sleeves 9 are respectively arranged at the upper ends of the two moving rods 8. When the bidirectional lead screw 7 is rotated, the two moving rods 8 approach each other, driving the two semi-circular arc sleeves 9 to approach each other.

[0028] In addition, a spring 10 is arranged inside the arc sleeve 9, and the spring 10 is connected to the limit sleeve 11. When the two arc sleeves 9 approach each other, the two limit sleeves 11 limit and fix the first pipe 3, and the spring 10 reduces the extrusion of the limit sleeve 11 on the first pipe 3 through its elastic action, ensuring the smoothness of the first pipe 3 during nitrogen transportation. At this time, the first pipe 3 remains stable, making the connection between the first pipe 3 and the second pipe 4 perpendicular to the support plate 5, facilitating the sealing detection thereof.

[0029] During the detection, since the detection component includes a gear disk 14 located in the empty groove 12, of course, the second pipe 4 needs to pass through the gear disk 14 without affecting the rotation of the gear disk 14. The rotating ring on the lower side of the gear disk 14 is rotatably connected to the rotating groove 13 opened inside the empty groove 12. At the same time, a driving wheel 15 is rotatably arranged on one side of the support plate 5, and the driving wheel 15 is driven by a motor. When the driving wheel 15 rotates, by using the meshing of the driving wheel 15 and the gear disk 14 in the opening on one side of the empty groove 12, the gear disk 14 is automatically rotated, improving the detection efficiency.

[0030] In addition, a spray pipe 21 is arranged above the gear disk 14. The height of the spray pipe 21 is adapted to the height of the connection between the first pipe 3 and the second pipe 4. The soapy water sprayed from the spray pipe 21 can be accurately located at the connection between the first pipe 3 and the second pipe 4.

[0031] Further, a connection block 16 is arranged on the gear disk 14. A storage cylinder 19 is movably arranged above the connection block 16. The storage cylinder 19 is filled with soapy water. At the same time, the soapy water in the storage cylinder 19 is transported to the spray pipe 21 through a micro pump 20 and a pipeline, realizing the spraying of the spray pipe 21.

[0032] For the convenience of disassembly, a plug rod 18 is arranged above the connection block 16. The plug rod 18 is in plug-in fit with the bottom of the storage cylinder 19. This way is convenient for removing the storage cylinder 19 and adding water to the inside of the storage cylinder 19.

[0033] When the gear disk 14 drives the spray pipe 21 to rotate, in order to realize smooth water spraying, a sliding groove 17 is opened at the bottom of the connection block 16. The connection block 16 is slidably connected to the frame of the empty groove 12 through the sliding groove 17. The gear disk 14 will drive the connection block 16 to rotate at the same time, making the storage cylinder 19 move along with it.

[0034] In summary, the working principle of a low-loss coke dry quenching production device according to an embodiment of the present utility model is as follows: The first pipe 3 is clamped and supported by two limit sleeves 11 to keep the first pipe 3 stable. At the same time, the second pipe 4 is restricted by the support plate 5 so that the connection part between the first pipe 3 and the second pipe 4 remains in a vertical state. Combining the meshing of the driving wheel 15 and the gear disk 14, the gear disk 14 drives the spray pipe 21 to make a circular motion, and the spray pipe 21 sprays annularly towards the connection part between the first pipe 3 and the second pipe 4. After the soapy water is sprayed, the state of the sealing performance can be determined by observing whether bubbles are generated in the soapy water.
