Abstract
Description
Technical Field
[0001] The utility model relates to a fire extinguishing device, in particular to a fire extinguishing device for spontaneous combustion of gangue piles. Background Art
[0002] A large amount of gangue is generated during coal mining and coal washing processes. The gangue accumulates to form gangue piles. Gangue has a tendency of spontaneous combustion, resulting in frequent spontaneous combustion fires of gangue piles. Different from the spontaneous combustion of coal, the ignition point of gangue spontaneous combustion is more difficult to determine. At the same time, a large amount of harmful gases and toxic substances such as SO2, CO, and H2S are generated, seriously polluting the atmosphere and water resources.
[0003] In the early stage, the governance technology of gangue pile spontaneous combustion mainly adopted methods such as excavating the fire source and covering it with water. In the 19th century, with the progress of science and technology and the improvement of people's environmental protection awareness and sustainable development concept, many new discoveries have been made about the law of gangue pile spontaneous combustion. Gradually, various prevention and control methods such as grouting fire extinguishing method, foam fire extinguishing method, and low-temperature inert gas fire extinguishing method have emerged. However, there are still problems such as large investment and unsatisfactory treatment effect in the current governance. Content of the Utility Model
[0004] The purpose of the utility model is to provide a fire extinguishing device, which solves the problems of large investment in the current governance of gangue spontaneous combustion but unsatisfactory treatment effect.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A fire extinguishing device includes a grouting machine, a first pipeline, multiple second pipelines, and a third pipeline. The grouting machine is connected to the first pipeline through a connector. Multiple second pipelines are sequentially connected between the first pipeline and the third pipeline; a number of diversion holes are opened on the first pipeline, the second pipelines, and the third pipeline, and a fire extinguishing medium is contained in the grouting machine.
[0007] Further, both ends of the first pipeline are communicated. One end is communicated with the grouting machine through a connector, and the other end is communicated with the second pipeline through a flange.
[0008] Further, multiple second pipelines are sequentially communicated with each other. One end of the second pipeline at the head end is communicated with the first pipeline through a flange, and the other end is communicated with the next second pipeline through a flange; one end of the second pipeline at the tail end is communicated with the previous second pipeline through a flange, and the other end is communicated with the third pipeline through a flange.
[0009] Further, one end of the third pipeline is communicated with the second pipeline through a flange, and the other end is closed.
[0010] Further, the first pipeline, the second pipelines, and the third pipeline use seamless steel pipes with a diameter of 50 mm.
[0011] Further, the spacing between adjacent diversion holes gradually increases from the side of the grouting machine to the third pipeline.
[0012] Further, an adjusting lever is provided on the grouting machine.
[0013] Further, the fire extinguishing medium uses a temperature-sensitive gel material.
[0014] Compared with the prior art, the utility model has the following advantages and beneficial effects:
[0015] In view of the difficulty in determining the spontaneous combustion ignition point of the gangue mountain, in the complex stacking environment of the gangue mountain, a grouting machine is used, and a temperature-sensitive gel material is used as the medium. Finally, the temperature-sensitive gel is injected into the entire oxidation and combustion area of the gangue mountain through the first pipeline, the second pipeline and the third pipeline. Utilizing the characteristic that the temperature-sensitive gel material has strong fluidity at normal temperature, it can flow into the gangue mountain faster. The temperature-sensitive gel material that undergoes a phase change when heated will immediately undergo a phase change and wrap when encountering a high-temperature fire area, achieving targeted rapid cooling and fire extinguishing. The utility model not only has a simple structure and low cost, but also has a fast fire extinguishing speed. Description of the Drawings

[0020] Such as Figure 1 And Figure 4As described above, a fire extinguishing device includes a grouting machine, a first pipeline 1, multiple second pipelines 2, and a third pipeline 3. The grouting machine is connected to the first pipeline 1 through a connector 4, and multiple second pipelines 2 are sequentially connected between the first pipeline 1 and the third pipeline 3. A number of diversion holes 5 are opened on the first pipeline 1, the second pipelines 2, and the third pipeline 3. The grouting machine is filled with a fire extinguishing medium, and the fire extinguishing medium uses a temperature-sensitive gel material. The first pipeline 1, multiple second pipelines 2, and the third pipeline 3 are connected to form a grouting pipeline, and the first pipeline 1 is connected to the grouting machine. Then, technicians drill a hole from the outside to the inside of the waste rock mountain through a drill. The size of the hole is adapted to the grouting pipeline. Then, the grouting pipeline is buried in the oxidation combustion area 7 of the waste rock mountain 8. The grouting machine is started, and the fire extinguishing medium in the grouting machine is injected into the oxidation combustion area 7 of the waste rock mountain 8 through the diversion holes 5 on the grouting pipeline. The temperature-sensitive gel material will undergo a phase change when encountering heat and immediately wrap around when encountering a high-temperature fire area, achieving targeted rapid cooling and fire extinguishing. An adjusting lever is provided on the grouting machine, and technicians can also control the flow rate in the grouting pipeline by controlling the adjusting lever to control the fire extinguishing cost.
[0021] Both ends of the first pipeline 1 are connected. One end is connected to the grouting machine through a connector 4, and the other end is connected to the second pipeline 2 through a flange 6. Multiple second pipelines 2 are sequentially connected to each other. One end of the second pipeline 2 at the head end is connected to the first pipeline 1 through a flange 6, and the other end is connected to the next second pipeline 2 through a flange 6. One end of the second pipeline 2 at the tail end is connected to the previous second pipeline 2 through a flange 6, and the other end is connected to the third pipeline 3 through a flange 6. One end of the third pipeline 3 is connected to the second pipeline 2 through a flange 6, and the other end is closed. One end of the third pipeline 3 is closed by welding, which can effectively prevent the temperature-sensitive gel from being directly injected into the inside of the waste rock mountain 8, thereby causing uneven injection of the temperature-sensitive gel and affecting the fire prevention and extinguishing effect. The first pipeline 1, multiple second pipelines 2, and the third pipeline 3 are connected to form a grouting pipeline. The first pipeline 1, the second pipelines 2, and the third pipeline 3 use seamless steel pipes with a diameter of 50 mm. The distance between adjacent diversion holes 5 gradually increases from the side of the grouting machine to the third pipeline 3, so that the fire extinguishing medium is evenly injected into the waste rock mountain 8 to improve the fire extinguishing effect.
[0022] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions, or substitutions made by those skilled in the art within the essence of the present invention should also fall within the protection scope of the present invention.
