Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of fire extinguishing, and more particularly, to a forced convection superconduit gangue hill fire extinguishing device. Background Art

[0002] In the coal mining and related mining industries, the fire on the gangue hill is a serious and intractable problem. A large amount of coal waste is piled up on the gangue hill. Due to the internal physical and chemical reactions and the influence of external environmental factors, spontaneous combustion is extremely likely to occur. There are many deficiencies in traditional gangue hill fire extinguishing methods, and it is difficult to meet the current requirements for efficient and thorough fire extinguishing and adapting to complex environments.

[0003] Most of the gangue hill fire extinguishing methods adopt relatively simple and direct methods, such as watering to extinguish the fire, covering and isolating, etc. Although watering to extinguish the fire can reduce the temperature to a certain extent, due to the complex internal structure of the gangue hill, it is difficult to quickly export the heat, and the water is difficult to penetrate into the deep area, resulting in limited fire extinguishing effect and easy waste of water resources. The method of covering and isolating only temporarily prevents the contact between oxygen and combustible substances, and cannot fundamentally eliminate the internal heat. Once the covering layer is damaged or destroyed, the fire is likely to reignite.

[0004] Some traditional fire extinguishing devices have unreasonable structural designs and are difficult to adapt to the complex terrain and environment of the gangue hill. The surface of the gangue hill is often uneven, with a large number of obstacles and irregular areas. Traditional devices are difficult to be flexibly arranged and cannot effectively export the heat. Moreover, the sealing performance of these devices is poor, and leakage is likely to occur during heat transfer and gas exchange, resulting in low heat exchange efficiency and affecting the fire extinguishing effect.

[0005] In terms of heat exchange and circulation, traditional devices lack an efficient mechanism. Most of them rely on natural convection or simple ventilation methods for heat transfer, with slow heat exchange speed and unable to quickly reduce the temperature inside the gangue hill. Moreover, these devices cannot effectively control the distribution of oxygen, and it is difficult to reduce the contact opportunity between combustible substances and oxygen, with a high risk of reignition.

The diversion cavity of the diversion tube provides a stable transmission channel for the condensed liquid. When the gas in the condensation cavity of the convection guide member condenses into a liquid under the action of the convection fan, the liquid can smoothly flow into the diversion cavity through the interconnected interfaces on the diversion tube and be directionally transmitted under its guidance.

On the one hand, it promotes the faster dissipation of the heat on the outer surface of the superconducting tube into the air, improving the heat dissipation speed; on the other hand, it guides the more sufficient exchange of hot air and cold air inside the coal gangue mountain, reducing the temperature inside the coal gangue mountain.

[0018] Through the synergistic effect of the diversion tube, the superconducting tube, the convection guide member and the convection fan, the device can quickly extract the heat inside the coal gangue mountain, rapidly reduce the temperature of the coal gangue mountain below the critical temperature of coal spontaneous combustion, shorten the fire extinguishing time compared with the traditional fire extinguishing method, and achieve the rapid extinguishment of the fire on the coal gangue mountain. The continuous heat extraction and air circulation change the internal thermal environment and oxygen distribution of the coal gangue mountain, reduce the contact opportunity between combustible substances and oxygen, and lower the probability of re-ignition. Combining with the overall design of the device, it fundamentally reduces the possibility of re-ignition of the fire on the coal gangue mountain and ensures the thoroughness of the fire extinguishing work.

Specific embodiments The present disclosure will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present disclosure, rather than limiting the present disclosure.

[0025] In addition, in the description of this application, the terms “first”, “second” etc. are only used for distinguishing descriptions and cannot be construed as indicating or implying relative importance.

[0026] As Figures 1 to 5 shown, it shows a forced convection superconducting pipe goaf fire extinguishing device in an embodiment of this disclosure.

[0027] In some examples, for instance, as Figure 1 、 Figure 3 shown, the working medium inside the superconducting cavity 202 of the superconducting pipe 2 evaporates rapidly in the high-temperature environment of the goaf, and the steam quickly transfers heat from the high-temperature area to the condensation cavity 301 and condenses and flows back at the condensation cavity 301, forming an efficient heat cycle transfer mechanism. The diversion cavity 102 of the diversion pipe 1 provides a stable transmission channel for the condensed liquid. When the gas in the condensation cavity 301 of the convection guide member 3 condenses into a liquid under the action of the convection fan 4, the liquid can flow smoothly into the diversion cavity 102 through the interconnected interfaces on the diversion pipe 1 and is directionally transmitted under its guidance. The superconducting pipe 2 is sleeved outside the diversion pipe 1, and its structure is more compact and suitable for the coal mine environment, enabling it to still work efficiently in the complex terrain and environment of the goaf. Even if the surface of the goaf is uneven or there are obstacles, the combination of the superconducting pipe 2 and the diversion pipe 1 can be flexibly arranged with the assistance of a drilling machine to ensure that heat dissipation is not affected.

[0028] The sealed connection between the first and second communication ports 302, 303 of the convection guide 3 and the inlet 103 of the flow conduit 1 ensures the tightness of the entire internal system. The convection fan 4 blows air into the convection guide 3, accelerating the flow of air within the condensation chamber 301 and enhancing heat exchange. This, on the one hand, accelerates the dissipation of heat from the outer surface of the superconduct 2 into the air, increasing the heat dissipation rate. On the other hand, it guides a more efficient exchange of hot and cold air within the waste rock pile, reducing the temperature within the waste rock pile.

[0029] Through the coordinated action of the flow guide duct 1, superconducting tube 2, convection guide 3, and convection fan 4, the device rapidly removes heat from the waste pile, rapidly reducing its temperature to below the critical temperature for spontaneous combustion of coal. This shortens fire extinguishing time compared to traditional firefighting methods, enabling rapid extinguishment of waste pile fires. Continuous heat removal and air circulation alter the thermal environment and oxygen distribution within the waste pile, reducing the contact between combustible materials and oxygen and lowering the probability of re-ignition. Combined with the overall design of the device, this fundamentally reduces the possibility of re-ignition of waste pile fires and ensures the thoroughness of firefighting.

[0030] In some examples, for example, Figures 1 to 5 As shown, the convection passage 104 formed by the guide wall 101 provides a directional and efficient transmission channel for the gas. The gas transmitted through the convection passage 104 can directly reach the combustion position of the waste rock pile. Compared with the traditional random diffusion gas transmission method, the time for the gas to reach the combustion position is shortened, the efficiency of gas transmission is improved, and it is ensured that the fire extinguishing gas can act on the fire source in time. Before the convection passage 104 guides the airflow into the combustion position, it uses the high temperature environment of the waste rock pile to make oxygen and carbon dioxide react to produce carbon monoxide. This process consumes part of the oxygen and reduces the oxygen content in the gas entering the combustion position. The guide port 304 of the convection guide 3 leads to the convection passage 104, which realizes the precise guidance of the gas blown out by the convection fan 4, avoids the disordered flow of gas, ensures that the gas can smoothly enter the convection passage 104, and then reach the combustion position, thereby enhancing the fire extinguishing effect.

[0031] The gas blown out by the convection fan 4 enters the convection passage 104 through the guide port 304, forming an effective gas circulation. Compared with natural ventilation, the gas circulation speed is increased by about 70%, which can not only quickly transport the carbon monoxide generated by the reaction to the combustion position, but also promptly remove the heat generated by the combustion, accelerate the cooling process of the combustion area, and improve the fire extinguishing efficiency. The synergistic effect of the guide wall 101, the convection guide 3 and the convection fan 4 achieves a dual flame retardant and cooling effect of reducing the oxygen content of the gas and lowering the temperature, thereby improving the fire extinguishing efficiency of the device. Compared with traditional waste rock pile fire extinguishing equipment, the overall fire extinguishing time is shortened, and waste rock pile fires can be extinguished more quickly and effectively, reducing the losses caused by the fire.

[0032] In some examples, for instance, as Figures 1 to 5 shown, a vacuum sleeve 5 is disposed between the diversion wall 101 and the pipe wall 201, and its vacuum chamber 501 effectively blocks the heat transfer between the diversion wall 101 and the pipe wall 201 in the ways of air conduction and convection. Compared with the structure without a vacuum sleeve, the vacuum sleeve 5 reduces the heat transfer between the diversion wall 101 and the pipe wall 201, reduces the energy loss caused by heat dissipation, maintains the efficient heat transfer performance of the superconducting pipe 2, and ensures the continuous export of the heat inside the gangue mountain. The stable temperature environment helps prevent the diversion wall 101 and the pipe wall 201 from deforming due to thermal expansion and contraction, and extends the service life of each component of the device.

[0033] The seal 6 is disposed through the corresponding first through hole 105, second through hole 205, and third through hole 502, effectively preventing the communication between the diversion chamber 102, the condensation chamber 301, and the vacuum chamber 501 and the outside world, ensuring the integrity of the internal gas circulation system of the device, maintaining the stability of the gas pressure and flow rate in the convection path 104, and providing guarantee for the smooth progress of the fire extinguishing work. The through hole 601 on the seal 6 provides a precise communication channel between the convection path 104 and the external environment, avoiding the disorderly escape of gas or the entry of external impurities. This design makes the gas flow direction in the convection path 104 more stable, ensures that the airflow can smoothly reach the combustion position to participate in the fire extinguishing reaction, and enables the fire at the ignition point in the non-combustion core position to be extinguished. The vacuum sleeve 5 reduces the heat dissipation and the energy consumption required for the device to maintain the fire extinguishing effect, and the seal 6 ensures the effective utilization of gas and reduces the loss caused by gas leakage.

[0034] In some examples, for instance, as Figures 1 to 5 shown, the spiral guiding groove 106 on the inner wall of the convection path 104 provides a clear and stable spiral flow path for the airflow. Compared with the ordinary straight cylindrical convection path, the gas advances orderly in a spiral shape under the guidance of the spiral guiding groove 106, avoiding the turbulence and disorderly diffusion of the airflow. The time for the airflow to reach the combustion position is shortened, ensuring that the fire extinguishing gas can quickly and accurately reach the fire source point and play the fire extinguishing role in time. The spiral guiding groove 106 makes the airflow generate a spiral upward or downward movement during the flowing process, and this movement increases the contact area and contact time between the airflow and the inner wall of the convection path 104 and the surrounding gas. The contact area for the reaction of consuming oxygen is increased. Through the guidance of the spiral guiding groove 106, the flame retardant gas carried by the airflow, such as carbon monoxide generated by the reaction, can be more evenly distributed at the combustion position. The oxygen concentration in the combustion area is effectively reduced, the combustion reaction is inhibited, and the reliability and stability of fire extinguishing are improved.

[0035] The first through-hole 105 is located within the spiral guiding groove 106, and the convex portion 107 of the spiral guiding groove 106 is equipped with a guiding inclined surface 108, which can precisely guide the airflow. When the airflow flows along a spiral path within the spiral guiding groove 106, the guiding inclined surface 108 can smoothly and efficiently introduce it into the through-hole 601. This structure can optimize the gas flow rate entering the through-hole 601. Due to the constraints of the spiral guiding groove 106 and the guiding inclined surface 108, the gas flow rate does not experience sudden changes during the introduction process but remains stable. The first through-hole 105, the second through-hole 205, and the third through-hole 502 are sealed by the seal 6, and the first through-hole 105 being located within the spiral guiding groove 106 further enhances the sealing effect. The guiding inclined surface 108 not only guides the airflow but also blocks impurities and foreign objects from invading the seal 6 from the spiral guiding groove 106, reducing the risk of damage to the seal 6.

[0036] The precise airflow guidance and stable gas flow rate enable the fire extinguishing gas to quickly and accurately reach the combustion location, giving full play to the fire extinguishing effect. The extended service life of the seal 6 reduces the replacement frequency of the seal and lowers the maintenance cost. At the same time, the improved operational stability of the device reduces the downtime and repair costs caused by failures.

[0037] In some examples, for instance, as Figures 1 to 5 shown, the rotating scraping member 9 can be installed within the condensation chamber 301 of the convection plate 305 with relatively low rotational friction through a bearing, and its top abuts against the top wall of the condensation chamber 301. During the operation of the device, the rotating scraping member 9 rotates continuously, capable of promptly scraping off the liquid condensed on the top wall of the condensation chamber 301 and introducing it into the diversion chamber 102. Compared with the design without a rotating scraping member, the collection efficiency of the condensed liquid is improved, avoiding the accumulation of condensed liquid on the top wall, ensuring a stable supply of condensed liquid in the cooling circulation system, and providing a guarantee for continuous and efficient fire extinguishing. The scraping action of the rotating scraping member 9 reduces the thickness of the liquid film formed by the condensed liquid on the top wall of the condensation chamber 301, increases the contact area between the gas and the top wall of the condensation chamber 301, and enhances the condensation effect. The structure of the rotating scraping member 9 is relatively simple and is independently arranged within the condensation chamber 301, facilitating installation, disassembly, and maintenance. The rotating scraping member 9 has scraping blades, which introduce the condensed liquid into the diversion chamber 102, ensuring the quantity of the heat-conducting medium within the superconductor 2, and thus guaranteeing the cooling effect.

[0038] In some examples, for instance, as Figures 3 to 5As shown, the thickened portion 206 and the inner conical heat conduction portion 207 at the bottom of the pipe wall 201 increase the heat conduction area at the bottom of the superconducting pipe 2, and the inner conical structure can guide the heat to be concentrated and conducted towards the air outlet 208. The inner conical heat conduction portion 207 guides the airflow in the convection passage 104 towards the air outlet 208, enabling the airflow to reach the combustion position more accurately. This ensures that the fire extinguishing gas can directly act on the fire source and improves the utilization efficiency of the fire extinguishing gas. The efficient heat conduction and precise delivery of the fire extinguishing gas can quickly reduce the temperature at the combustion position and change the surrounding thermal environment and oxygen distribution, reducing the contact opportunity between combustible substances and oxygen. The thickened portion 206 enhances the structural strength at the bottom of the superconducting pipe 2, enabling it to better withstand external forces and thermal stresses in the complex environment of the coal gangue mountain.

[0039] In some examples, for instance, as Figures 3 to 5 shown, the convection disk 305 has a gas guide pipe 307. The gas guide pipe 307 has a first communication port 302 and is located inside the superconducting cavity 202. The gas guide pipe 307 is inclined and faces the rotating scraping member 9.

[0040] The gas guide pipe 307 is inclined and arranged inside the superconducting cavity 202 and faces the rotating scraping member 9, such that the gas entering from the first communication port 302 directly flows towards the rotating scraping member 9. During the gas flow, it can contact the surface of the rotating scraping member 9, promoting the rotation of the rotating scraping member 9, ensuring the scraping effect, and thus further enhancing the condensation effect. Since the gas guide pipe 307 guides the gas to flow towards the rotating scraping member 9, the condensed liquid can be more smoothly scraped off by the rotating scraping member 9 and introduced into the diversion cavity 102.

[0041] In some examples, for instance, as Figures 4 to 5 shown, the connecting member 7 penetrates through the vacuum sleeve 5 to realize the connection between the superconducting cavity 202 and the diversion cavity 102, building a direct and efficient channel for the heat conduction medium to flow between the two. The presence of the connecting member 7 makes the temperature distribution between the superconducting cavity 202 and the diversion cavity 102 more balanced. It avoids the occurrence of local overheating or overcooling phenomena, ensures the operation of the entire device in a stable temperature environment, and reduces equipment damage caused by thermal expansion and contraction.

[0042] During the circulation process, the connecting member 7 can play a role in supplementing and updating the coolant. When the coolant in the diversion cavity 102 deteriorates in performance due to heat absorption, relatively low-temperature coolant can be obtained from the superconducting cavity 202 through the connecting member 7, ensuring the effectiveness of the coolant. The connecting member 7 penetrates through the vacuum sleeve 5 and connects the superconducting cavity 202 and the diversion cavity 102, enhancing the connection tightness and structural integrity between the various components of the device.

[0043] In some examples, for instance, as Figure 1As shown, the gas cylinder 8 blows carbon dioxide into the convection plate 305 through the air duct 801, increasing the carbon dioxide content in the gas entering the convection passage 104. As a flame-retardant gas, carbon dioxide can effectively reduce the oxygen concentration in the combustion area and inhibit the combustion reaction. During the process of entering the convection plate 305, the carbon dioxide is mixed with the gas blown by the convection fan 4, further reducing the temperature of the gas entering the condensation chamber 301. The carbon dioxide introduced by the gas cylinder 8 can share part of the working pressure of the convection fan 4, reducing the damage caused to the convection fan 4 by high-temperature gas. Compared with the device without using the gas cylinder, the working temperature of the convection fan 4 is reduced, the failure rate caused by overheating is reduced, the service life of the convection fan 4 is extended, and the stable operation of the equipment is ensured.
