Description

Technical Field

[0001] This utility model relates to the field of cooling wall technology, and more specifically, to a water source switching device for water leakage in blast furnace cooling walls. Background Technology

[0002] The pipes inside the blast furnace cooling wall generally carry soft water to cool the blast furnace. However, over time, leaks are inevitable in the blast furnace cooling wall. Due to the high temperature inside the blast furnace and the inability to shut it down immediately when leaks occur, the soft water will leak out, causing significant losses. Furthermore, after a leak occurs, the water pressure in other parts of the cooling wall will be insufficient, affecting the water flow rate and impacting the cooling of the blast furnace. Utility Model Content

[0003] The purpose of this invention is to solve the problem of increased costs due to water leakage in cooling wall pipes, and to design a water source switching device for water leakage in blast furnace cooling walls.

[0004] To achieve the above objectives, the technical solution of this utility model is a water source switching device for blast furnace cooling wall leakage, comprising multiple cooling walls, an inlet pipe installed at the lower end of each cooling wall, an outlet pipe installed at the upper end of each cooling wall, the multiple cooling walls being longitudinally stacked on the blast furnace, the inlet pipe on the lowest cooling wall being supplied with water through a water supply pipe, a first valve installed at the outlet pipe, the outlet end of the first valve being connected to the inlet pipe above it, a water guide provided on one side of each cooling wall, the water guide being able to close the first valve when a pipe on a certain layer of cooling wall leaks, and guide the water discharged from the outlet pipe below this cooling wall into the inlet pipe above this cooling wall, a backup water source connector provided on one side of each cooling wall, the backup water source connector being able to guide industrial water into the pipe of the damaged cooling wall.

[0005] Furthermore, the water guide includes a water guide pipe connected to the water supply pipe, and a plurality of second valves are installed on the water guide pipe. No second valve is provided on the side of the lowest cooling wall. The second valves are located on the other cooling walls and correspond one-to-one. The second valves are connected to the water inlet pipes of the corresponding cooling walls.

[0006] Furthermore, the backup water source connector includes a third valve installed on one side of the inlet pipe, the third valve being connected to an industrial water inlet pipe, and a fourth valve installed on one side of the outlet pipe, the fourth valve being connected to an industrial water outlet pipe.

[0007] Furthermore, the industrial water inlet pipe can guide industrial water from the industrial water pipe on the blast furnace into the inlet pipe.

[0008] Furthermore, a pressure gauge is installed at the water outlet pipe.

[0009] The beneficial effects of this utility model are as follows: Soft water is supplied to the pipes inside the cooling wall through the water supply pipeline. When a pipe in a certain layer of the cooling wall is damaged and leaks, the first valve at the corresponding position is turned off, and then the water guide can bypass the pipes of this layer of the cooling wall to supply water. This can prevent the waste of soft water, and also ensure water pressure and water flow rate to ensure the cooling of the blast furnace. Industrial water can be introduced into this layer of the cooling wall through the backup water source connector, which can prevent the cooling wall from being damaged. Moreover, industrial water is relatively cheap, which can reduce costs. Attached Figure Description

[0011] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. 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 protection scope of this utility model.

[0012] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0013] This utility model provides, for example Figure 1-2The device shown is a water source switching device for blast furnace cooling wall leakage, comprising multiple cooling walls 1, with an inlet pipe 2 installed at the lower end of the cooling wall 1 and an outlet pipe 3 installed at the upper end of the cooling wall 1. The multiple cooling walls 1 are stacked longitudinally on the blast furnace. The inlet pipe 2 on the lowermost cooling wall 1 is supplied with water through a water supply pipe 4. A first valve 5 is installed at the outlet pipe 3, and the outlet end of the first valve 5 is connected to the inlet pipe 2 above it. A water guide 6 is provided on one side of the cooling wall 1. When the pipe on a certain layer of cooling wall 1 leaks, the water guide 6 can close the first valve 5 and guide the water discharged from the outlet pipe 3 below the cooling wall 1 into the inlet pipe 2 above the cooling wall 1. A backup water source connector 7 is provided on one side of the cooling wall 1. The backup water source connector 7 can guide industrial water into the pipe of the damaged cooling wall 1.

[0014] The process of switching water sources when the pipes leak is as follows: Under normal circumstances, all the first valves 5 are open. The water supply pipe 4 allows soft water to flow in the pipes of the cooling wall 1 through the inlet pipe 2, outlet pipe 3 and the first valves 5, thereby cooling the blast furnace. When the pipes of a certain layer of cooling wall 1 are damaged and leak, the first valve 5 below this cooling wall 1 is closed. The water guide 6 can bypass the pipes of this layer of cooling wall 1 and supply water to the pipes of the cooling wall above it, thereby preventing the soft water from continuing to leak. The backup water source connector 7 can introduce industrial water into the pipes in this layer of cooling wall 1 to cool the blast furnace and prevent the cooling wall 1 from being damaged.

[0015] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 The water guide 6 includes a water guide pipe 8 connected to the water supply pipe 4. Multiple second valves 9 are installed on the water guide pipe 8. No second valve 9 is provided on the side of the lowest cooling wall 1. The second valves 9 are located on the other sides of the cooling walls 1 and correspond one-to-one. The second valves 9 are connected to the water inlet pipes 2 of the corresponding cooling walls 1.

[0016] The process by which the water guide 6 bypasses the damaged cooling wall 1 is as follows: When the cooling wall 1 of layer X is damaged and leaks, the first valve 5 at the lower end of this layer of cooling wall 1 is closed. The water outlet pipe 3 at the upper end of the cooling wall 1 of layer X-1 cannot supply soft water to the water inlet pipe 2 of layer X through the first valve 5. The second valves 9 of layers X-1 and X+1 are opened, so that the soft water can flow out through the water outlet pipe 3 and the second valve 9 at the upper end of the cooling wall 1 of layer X-1 and enter the water guide pipe 8. Then, it enters the water inlet pipe 2 through the second valve 9 of layer X+1, thereby bypassing the damaged cooling wall 1 and preventing the waste of soft water.

[0017] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2The backup water source connector 7 includes a third valve 10 installed on one side of the inlet pipe 2, the third valve 10 being connected to an industrial water inlet pipe 11, and a fourth valve 12 installed on one side of the outlet pipe 3, the fourth valve 12 being connected to an industrial water outlet pipe 13.

[0018] The backup water supply connector 7 supply process is as follows: opening the third valve 10 and the fourth valve 12 allows external industrial water to enter the pipe of the cooling wall 1 through the industrial water inlet pipe 11, the third valve 10, and the inlet pipe 2, and then be discharged through the outlet pipe 3, the fourth valve 12, and the industrial water outlet pipe 13, thereby cooling the blast furnace and protecting the cooling wall.

[0019] The industrial water inlet pipe 11 can guide the industrial water in the industrial water pipe on the blast furnace into the water inlet pipe 2, eliminating the need for additional industrial water supply and reducing costs.

[0020] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 A pressure gauge 14 is installed at the water outlet pipe 3. The water pressure of the water outlet pipe 3 can be detected by the pressure gauge 14, which makes it easier to determine which layer of cooling wall 1 is leaking water.

[0021] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
