Description

Technical Field

[0001] This application belongs to the field of blast furnace technology, specifically relating to a device for treating blockages in cooling wall water pipes. Background Technology

[0002] Blockage of blast furnace cooling wall water pipes after damage may cause the following technical problems:

[0003] First, blockage will reduce or stop the flow of cooling water in the pipe. Cooling water will enter the blast furnace in large quantities through the damaged part. When a large amount of water meets the molten slag and iron in the blast furnace, it will cause an explosion, which will pose a serious safety threat to the air supply system, furnace top equipment, gas pipeline network, furnace shell, etc. At the same time, it will cause serious production accidents such as increased fuel consumption, large cooling inside the furnace or freezing of the hearth.

[0004] Secondly, the blockages consist of dense materials such as coke particles, pellets, sintered ore particles, and slag iron powder inside the blast furnace. At the same time, the pipes that lead to the industrial water cooling outlet have a "T"-shaped 90° bend, making them difficult to clean and unclog after sedimentation.

[0005] Third, pipeline dredging requires workers to carry water and gas for extended periods, posing a threat to their personal safety.

[0006] In existing technologies, to resolve pipe blockages, workers need to disassemble the water pipe and immediately use a sledgehammer to strike and vibrate it, while inserting flexible but hard objects such as thick iron wire into the bypass pipe or valve to clear the blockage. However, using this method can lead to the following problems:

[0007] First, at least two people are required to operate this system, and the operation will take 10-20 minutes or even longer.

[0008] Second, prolonged operation with water or gas presents a threat to personal safety.

[0009] Third, pipelines with a "T"-shaped 90° bend at the water outlet are very difficult to clean and unclog after material accumulation and blockage, making operation extremely difficult.

[0010] Fourth, due to the difficulty in handling it, it is easy to cause blast furnace shutdown incidents. Utility Model Content

[0022] Based on the same inventive concept, this utility model also provides a method for dealing with blockages in cooling wall water pipes.

[0047] This application is described below with reference to the accompanying drawings and specific embodiments:

[0048] The cooling wall water pipe blockage treatment device provided in this embodiment aims to solve, to at least some extent, the technical problem of the difficulty in clearing blockages after damage to the blast furnace cooling wall water pipes.

[0049] Figure 1 This is a structural schematic diagram of a cooling wall water pipe blockage treatment device according to some embodiments. (Combined with...) Figure 1 This application provides a cooling wall water pipe blockage treatment device. The cooling wall water pipe includes a first pipe 50, a second pipe 60, and a third pipe 70. The first pipe 50 has a damaged opening. The cooling wall water pipe blockage treatment device includes a first three-way pipe 10, a second three-way pipe 20, a first shut-off valve 30, and a second shut-off valve 40. The first three-way pipe 10 has a fourth pipe 11, a fifth pipe 12, and a sixth pipe 13. The fourth pipe 11 communicates with the flow channel of the first pipe 50, the fifth pipe 12 communicates with the flow channel of the third pipe 70, and the sixth pipe 13 is located between the fourth pipe 11 and the fifth pipe 12. The second three-way pipe 20 has a seventh pipe 21, an eighth pipe 22, and a ninth pipe 23. The seventh pipe 21 communicates with the sixth pipe 13, the ninth pipe 23 communicates with the second pipe 60, and the ninth pipe 23 is located between the seventh pipe 21 and the eighth pipe 22. The first shut-off valve 30 is located on the eighth pipe 22 and is used to control the opening and closing of the eighth pipe 22. The second shut-off valve 40 is located on the ninth pipe 23 and is used to control the opening and closing of the ninth pipe 23.

[0050] The first tee pipe 10 is the pipeline with the "T"-shaped 90° bend described in the background art of this application.

[0051] The second pipe 60 and the first pipe 50 are independent pipes, and the second pipe 60 is undamaged and can transport cooling water normally.

[0052] When a blockage occurs in the fourth pipe 11 and / or the connection between the fourth pipe 11 and the sixth pipe 13, the first shut-off valve 30 is closed and the second shut-off valve 40 is opened. Fluid in the second pipe 60 then flows sequentially through the ninth pipe 23 and the seventh pipe 21 into the sixth pipe 13, allowing the fluid to backflush the blockage in the fourth pipe 11 and / or the connection between the fourth pipe 11 and the sixth pipe 13. Within a set time, the second shut-off valve 40 is opened and closed multiple times, using the water supply from the second pipe 60 to perform multiple backflushing operations on the fourth pipe 11 and / or the connection between the fourth pipe 11 and the sixth pipe 13. This achieves the backflushing operation by impacting the fourth pipe 11 and / or the connection between the fourth pipe 11 and the sixth pipe 13. The water hammer effect utilizes the backwash principle to disperse the blockage, allowing it to drain smoothly from the fourth pipe 11 and / or the connection between the fourth pipe 11 and the sixth pipe 13. This facilitates the removal of blockages at the fourth pipe 11 and / or the connection between the fourth pipe 11 and the sixth pipe 13. Only one worker is needed to operate the first shut-off valve 30 and the second shut-off valve 40, reducing the need for manpower. Furthermore, it eliminates the need to dismantle pipelines, reducing labor intensity. The time for clearing blockages is reduced from 10-20 minutes to 2-3 minutes, or even less. Workers also do not need to operate with water or gas present, ensuring worker safety and achieving rapid unblocking while preventing accidents.

[0053] Combination Figure 1 In some embodiments, to determine whether the blockage at the connection between the fourth pipe 11 and / or the sixth pipe 13 has been completely cleared, the cooling wall water pipe blockage treatment device further includes a tenth pipe 80 and a flow meter 90. The tenth pipe 80 is connected to the eighth pipe 22. The flow meter 90 is located in the tenth pipe 80 and is used to detect the flow rate of the tenth pipe 80.

[0054] When the fourth pipe 11 and / or the connection between the fourth pipe 11 and the sixth pipe 13 is not blocked, the second shut-off valve 40 is closed and the first shut-off valve 30 is opened, so that the fluid in the first pipe 50 enters the tenth pipe 80 in sequence through the fourth pipe 11, the sixth pipe 13, the seventh pipe 21 and the eighth pipe 22. The flow meter 90 detects the first flow value. During the process of the flow meter 90 detecting the flow of the tenth pipe 80, if the flow meter 90 detects the second flow value, and the second flow value is less than the first flow value, it indicates that the fourth pipe 11 and / or the connection between the fourth pipe 11 and the sixth pipe 13 is blocked.

[0055] When the fourth pipe 11 and / or the connection between the fourth pipe 11 and the sixth pipe 13 is blocked, a backflushing operation is performed. After one backflushing operation is completed, observe the value of the flow meter 90 after an interval of 5 to 8 seconds to obtain a third flow value. Compare the third flow value with the first flow value. If the third flow value is greater than or equal to the first flow value, it indicates that the blockage in the fourth pipe 11 and / or the connection between the fourth pipe 11 and the sixth pipe 13 has been completely flushed away. If the third flow value is less than the first flow value, the backflushing operation needs to be repeated to completely flush away the blockage in the fourth pipe 11 and / or the connection between the fourth pipe 11 and the sixth pipe 13.

[0056] Furthermore, a 3-5 minute interval is required between each backwash operation to prevent the cooling water in the first pipe from not flowing for an extended period, which could cause detonation inside the furnace.

[0057] In some embodiments, to facilitate the connection between the tenth pipe 80 and the eighth pipe 22, the cooling wall water pipe blockage treatment device further includes a first connector and a second connector. The first connector is located on the eighth pipe 22. The second connector is located on the tenth pipe 80 and is detachably connected to the first connector. The connection between the tenth pipe 80 and the eighth pipe 22 is achieved through the first connector and the second connector, which facilitates disassembly and assembly and improves installation efficiency.

[0058] In related technologies, when the water pipes of the blast furnace cooling wall are damaged, the original closed soft water circulation cooling is changed to an open-loop industrial water cooling method, that is, the original outlet water is changed to inlet water, and the inlet water is changed to outlet water. In other words, when the first pipe 50 is not damaged, the fluid flows from the third pipe 70 to the first pipe 50. When the first pipe 50 has a damaged opening, the fluid flows from the first pipe 50 to the third pipe 70.

[0059] Combination Figure 1 In some embodiments, when the first pipe 50 is not damaged, in order to ensure normal fluid flow, the cooling wall water pipe blockage treatment device further includes a third shut-off valve 100. The third shut-off valve 100 is located in the sixth pipe 13 and is used to control the opening and closing of the sixth pipe 13. That is, when the first pipe 50 is not damaged, the third shut-off valve 100 is closed, and the sixth pipe 13 is disconnected, so that the fluid in the third pipe 70 will only flow to the first pipe 50 through the fifth pipe 12 and the fourth pipe 11, avoiding interference with normal cooling operation. When the first pipe 50 has a damaged opening, the third shut-off valve 100 is opened, the sixth pipe 13 is opened, and the fluid in the first pipe 50 will flow to the sixth pipe 13 through the fourth pipe 11.

[0060] Combination Figure 1In some embodiments, when the first pipe 50 has a damaged opening, in order to ensure that the fluid in the first pipe 50 flows to the sixth pipe 13, the cooling wall water pipe blockage treatment device further includes a fifth shut-off valve 110. The fifth shut-off valve 110 is located in the third pipe 70 and is used to control the opening and closing of the third pipe 70. That is, when the first pipe 50 is not damaged, the third shut-off valve 100 is closed and the fifth shut-off valve 110 is opened, the sixth pipe 13 is disconnected, and the third pipe 70 is opened, so that the fluid in the third pipe 70 will only flow to the first pipe 50 through the fifth pipe 12 and the fourth pipe 11, avoiding interference with normal cooling operation. When the first pipe 50 has a damaged opening, the third shut-off valve 100 is opened, the sixth pipe 13 is opened, the fifth shut-off valve 110 is closed, the third pipe 70 is closed, and the fluid in the first pipe 50 will flow to the sixth pipe 13 through the fourth pipe 11.

[0061] Combination Figure 1 In some embodiments, to achieve communication between the sixth pipe 13 and the seventh pipe 21, the cooling wall water pipe blockage treatment device further includes an eleventh pipe 120, a third connector, and a fourth connector. The eleventh pipe 120 communicates with both the sixth pipe 13 and the seventh pipe 21. The third connector is located on the eleventh pipe 120. The fourth connector is located on the seventh pipe 21 and is detachably connected to the third connector. Communication between the eleventh pipe 120 and the seventh pipe 21 is achieved through the third and fourth connectors, facilitating disassembly and assembly and improving installation efficiency.

[0062] Combination Figure 1 In some embodiments, to achieve communication between the second pipe 60 and the ninth pipe 23, the cooling wall water pipe blockage treatment device further includes a twelfth pipe 130 and a thirteenth pipe 140. The twelfth pipe 130 is connected to the ninth pipe 23. The thirteenth pipe 140 is connected to the twelfth pipe 130 and the second pipe 60, and the fluid in the second pipe 60 sequentially enters the ninth pipe 23 through the thirteenth pipe 140 and the twelfth pipe 130.

[0063] In some embodiments, to facilitate the connection between the twelfth pipe 130 and the ninth pipe 23, the cooling wall water pipe blockage treatment device further includes a fifth connector and a sixth connector. The fifth connector is located on the twelfth pipe 130. The sixth connector is located on the ninth pipe 23 and is detachably connected to the fifth connector. The connection between the twelfth pipe 130 and the ninth pipe 23 is achieved through the first connector and the second connector, which facilitates disassembly and assembly and improves installation efficiency.

[0064] Combination Figure 1In some embodiments, when the first pipe 50 is not damaged, in order to ensure normal fluid flow, the cooling wall water pipe blockage treatment device further includes a fourth shut-off valve 150. The fourth shut-off valve 150 is located in the thirteenth pipe 140 and is used to control the opening and closing of the thirteenth pipe 140. That is, when the first pipe 50 is not damaged, the fourth shut-off valve 150 is closed, the thirteenth pipe 140 is disconnected, and the fluid in the second pipe 60 is prevented from being discharged through the thirteenth pipe 140, thus avoiding interference with normal cooling operation. When the first pipe 50 has a damaged opening, the fourth shut-off valve 150 is opened, the thirteenth pipe 140 is opened, and the fluid in the second pipe 60 will flow sequentially through the thirteenth pipe 140 and the twelfth pipe 130 to the ninth pipe 23, so that the fluid in the second pipe 60 can reach the fourth pipe 11 and / or the connection between the fourth pipe 11 and the sixth pipe 13, to perform a counter-impact operation on the blockage.

[0065] This application also provides a method for treating blockages in cooling wall water pipes, based on a cooling wall water pipe blockage treatment device. The method for treating blockages in cooling wall water pipes includes:

[0066] Step 1: When a blockage occurs in the fourth pipe 11 and / or at the connection between the fourth pipe 11 and the sixth pipe 13, close the first shut-off valve 30 and open the second shut-off valve 40. The fluid in the second pipe 60 enters the sixth pipe 13 through the ninth pipe 23 and the seventh pipe 21 in sequence, so that the fluid backflushs the blockage in the fourth pipe 11 and / or at the connection between the fourth pipe 11 and the sixth pipe 13.

[0067] Step two: Within a set time period, repeatedly open and close the second shut-off valve 40 to allow the water supply from the second pipe 60 to backwash the fourth pipe 11 and / or the connection between the fourth pipe 11 and the sixth pipe 13 multiple times, ensuring that any blockages in the fourth pipe 11 and / or the connection between the fourth pipe 11 and the sixth pipe 13 are completely flushed away. Specifically, the second shut-off valve 40 can be opened and closed 3 to 5 times within a time period of 3 to 6 seconds.

[0068] Furthermore, a complete backwashing operation should include 3 to 5 switching actions of the second shut-off valve 40, and after 3 to 5 switching actions of the second shut-off valve 40, the first shut-off valve 30 should be opened immediately.

[0069] When a blockage occurs in the fourth pipe 11 and / or the connection between the fourth pipe 11 and the sixth pipe 13, the first shut-off valve 30 is closed and the second shut-off valve 40 is opened. Fluid in the second pipe 60 then flows sequentially through the ninth pipe 23 and the seventh pipe 21 into the sixth pipe 13, allowing the fluid to backflush the blockage in the fourth pipe 11 and / or the connection between the fourth pipe 11 and the sixth pipe 13. Within a set time, the second shut-off valve 40 is opened and closed multiple times, using the water supply from the second pipe 60 to perform multiple backflushing operations on the fourth pipe 11 and / or the connection between the fourth pipe 11 and the sixth pipe 13. This achieves the backflushing operation by impacting the fourth pipe 11 and / or the connection between the fourth pipe 11 and the sixth pipe 13. The water hammer effect utilizes the backwash principle to disperse the blockage, allowing it to drain smoothly from the fourth pipe 11 and / or the connection between the fourth pipe 11 and the sixth pipe 13. This facilitates the removal of blockages at the fourth pipe 11 and / or the connection between the fourth pipe 11 and the sixth pipe 13. Only one worker is needed to operate the first shut-off valve 30 and the second shut-off valve 40, reducing the need for manpower. Furthermore, it eliminates the need to dismantle pipelines, reducing labor intensity. The time for clearing blockages is reduced from 10-20 minutes to 2-3 minutes, or even less. Workers also do not need to operate with water or gas present, ensuring worker safety and achieving rapid unblocking while preventing accidents.
