Description

Technical Field

[0001] This utility model belongs to the field of explosion prevention technology, and specifically relates to an explosion suppression system. Background Technology

[0002] Environments with high concentrations of flammable gases or dust are frequently found in coal mine tunnels, gas pumping stations, and oil refining areas. In these environments, the presence of an ignition source can easily cause an explosion of the flammable gas and dust mixture. To prevent explosions, existing technologies typically employ explosion-proof systems that use explosion suppressants to prevent disasters.

[0003] However, most explosion-proof areas in existing technologies are rectangular or irregular spaces, requiring multiple nozzles to spray the explosion suppressant. These nozzles are typically connected to a single powder supply line. Due to the structure of the protected area, the supply line may have a closed end. Furthermore, the supply line needs to provide an excessive amount of explosion suppressant powder, causing some powder to accumulate at the end of the pipe and come into contact with air. Over time, this deteriorates and corrodes the pipe and nozzles, preventing subsequent effective spraying of the explosion suppressant powder. Utility Model Content

It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0020] The explosion suppression system according to this utility model is described below with reference to the accompanying drawings.

[0021] like Figure 1 The diagram shown is a structural schematic of an explosion suppression system provided according to an embodiment of the present invention. The explosion suppression system includes: A detonator storage mechanism (not shown in the figure) stores a detonator. Multiple explosion suppressant delivery pipes 20, each explosion suppressant delivery pipe 20 has an inlet 21 and an outlet 22 at both ends along its length, and each explosion suppressant delivery pipe 20 is equipped with multiple nozzle assemblies 50 for spraying explosion suppressant to different locations in the area to be suppressed, and multiple inlets 21 are connected to the explosion suppressant storage mechanism. The recycling mechanism 30 has multiple recycling inlets 34, which are connected to multiple outlets 22 in a one-to-one manner. The recycling mechanism 30 is used to recycle excess explosion suppressant flowing out of the multiple outlets 22.

[0022] The explosion suppressant storage mechanism stores explosion suppressant and can transfer it to multiple explosion suppressant delivery pipes 20. Each explosion suppressant delivery pipe 20 has an inlet 21 and an outlet 22 at both ends along its length. The inlets 21 of the multiple explosion suppressant delivery pipes 20 are all connected to the explosion suppressant storage mechanism to ensure that the explosion suppressant can be smoothly transferred from the explosion suppressant storage mechanism to each explosion suppressant delivery pipe 20. Each explosion suppressant delivery pipe 20 is also equipped with multiple nozzle assemblies 50. These nozzle assemblies 50 can spray explosion suppressant at different locations in the area to be suppressed to achieve a comprehensive explosion suppression effect. In a specific implementation, the number and position of the nozzle assemblies 50 can be reasonably arranged according to the size and shape of the area to be suppressed to ensure that the explosion suppressant can evenly and fully cover the entire area to be suppressed. The recycling mechanism 30 has multiple recycling inlets 34, which are connected one-to-one with multiple outlets 22. The recycling mechanism 30 can recover excess explosion suppressant flowing out of the multiple outlets 22, thereby avoiding waste of explosion suppressant and simplifying the recycling process. In addition, the storage capacity of the recycling mechanism 30 can be reasonably designed according to actual needs to ensure that it can hold a sufficient amount of recycled explosion suppressant.

[0023] In one embodiment, such as Figure 2 The diagram shown is a cross-sectional schematic of the recycling mechanism 30 provided according to an embodiment of the present invention; as shown... Figure 3 The image shown is a partial cross-sectional schematic diagram of the recycling mechanism 30 provided according to an embodiment of the present invention; as shown... Figure 4The diagram shown is a top view of the explosion suppression system provided according to an embodiment of the present invention. The recovery mechanism 30 includes a recovery chamber 31, a transmission pipe 32, and a transmission assembly 33. Multiple recovery inlets 34 are formed through the body of the transmission pipe 32. One end of the transmission pipe 32 is connected to the recovery chamber 31. The transmission assembly 33 is disposed within the cavity of the transmission pipe 32 and is used to transfer the explosion suppressant from the transmission pipe 32 to the recovery chamber 31. Using the above-described recovery mechanism 30, excess explosion suppressant flowing out of multiple explosion suppressant delivery pipes 20 can be effectively recovered. The transmission assembly 33 ensures smooth transmission of the explosion suppressant within the transmission pipe 32 and its eventual entry into the recovery chamber 31 for storage. In specific implementations, the structure and performance of the transmission assembly 33 can be rationally designed according to the physical properties of the explosion suppressant and recovery requirements to ensure the stability and efficiency of the recovery process. Furthermore, to further improve recovery efficiency, the diameter and length of the transmission pipe 32 can also be rationally adjusted according to actual needs.

[0024] In a specific embodiment, such as Figure 4 As shown, multiple explosion suppressant delivery pipes 20 are arranged in parallel at intervals to make the explosion suppressant spraying range more uniform.

[0025] In one embodiment, such as Figure 2 and Figure 3 As shown, the transmission assembly 33 includes a transmission shaft 331, a helical blade 332, and a rotary drive. The transmission shaft 331 extends through the cavity of the transmission pipe 32 along its extension direction. The helical blade 332 is spirally wound around the outer periphery of the transmission shaft 331 along the axial direction. The outer wall of the helical blade 332 abuts against the inner wall of the transmission pipe 32. The rotary drive is driven to the transmission shaft 331 and is used to drive the transmission shaft 331 to rotate, so that the helical blade 332 drives the explosion suppressant to be spirally transmitted to the recovery chamber 31. The rotation of the helical blade 332 not only transmits the explosion suppressant from one end of the transmission pipe 32 to the other end, but also fully stirs and mixes the explosion suppressant, ensuring its uniformity. In addition, the helical design of the helical blade 332 can also increase the flowability of the explosion suppressant during transmission, preventing the explosion suppressant from clogging or accumulating in the transmission pipe 32. The rotary drive can be a motor or other rotary drive component to ensure that the transmission shaft 331 can rotate stably and continuously, thereby driving the spiral blades 332 and the explosion suppressant to rotate and be transported together. In specific implementations, the power and speed of the rotary drive can be reasonably adjusted according to the physical properties of the explosion suppressant and the recycling requirements to ensure the stability and efficiency of the recycling process.

[0026] In one embodiment, such as Figure 2 and Figure 3As shown, the explosion suppression system also includes multiple tilting plates 40 and multiple recovery inlets 34, which are arranged sequentially along the extension direction of the transmission pipe 32. One end of the tilting plate 40 is pivotally connected to the inner wall of the transmission pipe 32. The pitch of the spiral blade 332 is greater than the length of the tilting plate 40 when it is tilted parallel to the extension direction of the transmission pipe 32. The rotation of the spiral blade 332 can drive the tilting plate 40 to open or close the recovery inlet 34. If the outlet 22 of the explosion suppressant delivery pipe 20 remains open for a long time, it will reduce the gas pressure inside the explosion suppressant delivery pipe 20, which is not conducive to the transmission of the explosion suppressant in the explosion suppressant delivery pipe 20. Therefore, this embodiment of the invention also provides multiple tilting plates 40 to close the outlet 22 to prevent the gas pressure from being too low during the explosion suppressant spraying process, resulting in poor spraying effect.

[0027] Specifically, one end of the tilting plate 40 is pivotally connected to the inner wall of the transmission pipe 32, while the other end can tilt under the drive of the spiral blade 332, thereby opening or closing the opening corresponding to the recovery inlet 34. When the spiral blade 332 rotates to contact the tilting plate 40, it abuts against the tilting plate 40, causing the tilting plate 40 to close the recovery inlet 34 and prevent the explosion suppressant from entering the transmission pipe 32. When the spiral blade 332 continues to rotate and moves away from the tilting plate 40, the tilting plate 40 automatically opens the recovery inlet 34 due to its own gravity or the action of the elastic reset element. This design can not only effectively control the flow of the explosion suppressant and prevent excessive pressure and loss of explosion suppressant during spraying, but also smoothly recover the explosion suppressant to the recovery mechanism 30 when recovery is required. Furthermore, the pitch of the helical blade 332 is greater than the length of the tilting plate 40 when it is tilted parallel to the extension direction of the transmission tube 32. This design ensures that the helical blade 332 has a certain rotation angle, preventing contact between the helical blade 332 and the tilting plate 40, thus allowing the tilting plate 40 to open or close smoothly. Figure 2 and Figure 3 The state of the flip plate 40 is different. Figure 2 In the middle, the tilting plate 40 separates from the spiral blade 332, and the tilting plate 40 opens the recycling inlet 34 under gravity. Figure 3 The spiral blade 332 abuts against the tilting plate 40 so that the tilting plate 40 closes the recycling inlet 34.

[0028] In one embodiment, multiple recycling inlets 34 are evenly arranged, and the spiral blades 332 can drive multiple tilting plates 40 to open or close synchronously. The pitch of the spiral blades 332 is a fixed value, and the multiple recycling inlets 34 are evenly arranged. With the above structural design, it can be ensured that multiple recycling inlets 34 are opened or closed synchronously by the tilting plates 40, which simplifies the control process and improves the overall operating efficiency of the explosion suppression system.

[0029] In one embodiment, such as Figure 5 The diagram shows a schematic of the nozzle assembly 50 according to an embodiment of the present invention. The nozzle assembly 50 includes a nozzle element 51, which has multiple spiral nozzles 511 arranged circumferentially towards the area to be suppressed. The spray ends of the multiple spiral nozzles 511 face different directions, and the multiple spiral nozzles 511 are used to spray the suppressant delivered from the suppressant delivery pipe 20. Using the above-described nozzle assembly 50, the suppressant can be evenly sprayed to different positions within the area to be suppressed, thereby improving the suppression effect. The design of the multiple spiral nozzles 511 facing different directions allows the suppressant to cover a wider area, avoiding localized accumulation or absence of the suppressant within the area to be suppressed.

[0030] In one embodiment, the nozzle assembly 50 further includes a fixed tube 52 and a movable tube 53. The fixed tube 52 is mounted on the body of the explosion suppressant delivery tube 20, with one end connected to the cavity of the explosion suppressant delivery tube 20. One end of the movable tube 53 is rotatably connected to the fixed tube 52 and is connected to the fixed tube 52. The other end of the movable tube 53 is connected to the nozzle element 51. The fluid formed by the explosion suppressant entering from the fixed tube 52 can drive the nozzle element 51 and the movable tube 53 to rotate relative to the fixed tube 52. The movable tube 53 is rotatably connected to the fixed tube 52. When the fluid formed by the explosion suppressant is sprayed from the nozzle element 51, the fluid can drive the movable tube 53 to rotate, allowing multiple spiral nozzles 511 to spray in different directions, further improving the uniformity of the explosion suppressant distribution in the explosion suppression area. This design not only enhances the explosion suppression effect but also allows the nozzle assembly 50 to adapt to more complex explosion suppression environments, improving the flexibility and practicality of the explosion suppression system.

[0031] In one embodiment, such as Figure 6 The diagram shown is a structural schematic of the first embodiment of the pressurization assembly of this utility model. The explosion suppression system further includes a first pressurization assembly 60, which includes a first guide cylinder 61, a first inflation pipe 62, and a first inflation component. The first guide cylinder 61 is connected to the explosion suppressant delivery pipe 20 and is located on the delivery path of the explosion suppressant delivery pipe 20. The cavity extension direction of the first guide cylinder 61 is the same as the delivery direction of the explosion suppressant delivery pipe 20. A plurality of first guide holes 63 are obliquely opened through the first guide cylinder 61. The first inflation pipe 62 is sleeved on the outer periphery of the first guide cylinder 61. The inner wall of the first inflation pipe 62 and the outer wall of the first guide cylinder 61 together form a first inflation cavity 64. The first inflation cavity 64 is connected to the first guide holes 63. The first inflation component is used to deliver gas to the first inflation cavity 64.

[0032] During the transmission of the fluid formed by the explosion suppressant in the explosion suppressant transmission pipe 32, energy loss and insufficient gas pressure may occur. Therefore, in this embodiment of the invention, a first pressurization component 60 is provided on the explosion suppressant system. The first guide cylinder 61 of the first pressurization component 60 is connected to the explosion suppressant transmission pipe 20 and is located on the transmission path of the explosion suppressant transmission pipe 20. The design of the first guide cylinder 61 allows the explosion suppressant to pass smoothly. At the same time, multiple first guide holes 63 obliquely penetrate the first guide cylinder 61 to guide the high-pressure gas, thereby pressurizing the fluid formed by the explosion suppressant. The first inflation pipe 62 is sleeved on the outer periphery of the first guide cylinder 61, and together with the first guide cylinder 61, they form a first inflation chamber 64, which can receive the gas delivered by the first inflation component. This gas enters the fluid of the explosion suppressant through the first guide holes 63, providing additional power to the explosion suppressant, thereby enhancing its fluidity and spraying effect. Under the action of the first pressurization component 60, the explosion suppressant can be delivered to the nozzle component 50 more efficiently, improving the overall performance and explosion suppression effect of the explosion suppression system.

[0033] In one embodiment, such as Figure 7 As shown in the schematic diagram of the second embodiment of the pressurization component of this utility model, the explosion suppression system further includes a plurality of first spiral nozzles 65 disposed on the inner wall of the first guide cylinder 61 and corresponding one-to-one with a plurality of first guide holes 63. The first spiral nozzles 65 are used to spirally pressurize the airflow delivered by the first guide holes 63. The plurality of first spiral nozzles 65 enable the gas to form a spiral airflow after entering the first guide cylinder 61, thereby further enhancing the pressurization effect of the gas. This spiral pressurization method can not only increase the gas pressure, but also increase the gas flowability, so that the gas can be more fully mixed with the explosion suppressant, thereby improving the spraying effect and explosion suppression performance of the explosion suppressant.

[0034] In one embodiment, the nozzle assembly 50 can also serve as a second pressurization assembly with the function of spraying explosion suppressant. The second pressurization assembly includes: a second guide cylinder (not shown in the figure), a second inflation pipe (not shown in the figure), and a second inflation component (not shown in the figure). One end of the second guide cylinder is connected to the explosion suppressant delivery pipe 20, and the other end faces the area to be suppressed. Multiple second guide holes (not shown in the figure) are obliquely penetrating the second guide cylinder. The second inflation pipe is sleeved around the outer periphery of the second guide cylinder. The inner wall of the second inflation pipe and the outer wall of the second guide cylinder together form a second inflation chamber (not shown in the figure). The second inflation chamber is connected to the second guide holes. The second inflation component is used to deliver gas to the second inflation chamber. The structure of the second pressurization assembly can be found in [reference needed]. Figure 6The structure of the first pressurization pipe. The second inflation component of the second pressurization assembly can inflate the second inflation pipe with gas. The gas in the second inflation pipe further flows into the second guide tube to pressurize the explosion suppressant, thereby increasing the spraying distance and coverage of the explosion suppressant and further enhancing the explosion suppression effect.

[0035] In one embodiment, the nozzle assembly 50 further includes a second spiral nozzle (not shown), disposed on the inner wall of the second guide cylinder and corresponding one-to-one with a plurality of second guide holes. The second spiral nozzle is used to spirally pressurize the airflow delivered by the first guide hole 63 to further enhance the diffusion effect of the explosion suppressant. Through the design of the second spiral nozzle, the gas can form a spiral airflow after entering the second guide cylinder. This spiral airflow not only increases the gas pressure but also increases the gas flowability, allowing the gas to mix more thoroughly with the explosion suppressant, thereby improving the spray uniformity and explosion suppression performance of the explosion suppressant.

[0036] In one embodiment, such as Figure 1 As shown, the explosion suppression system also includes a one-way valve 70 and a switching valve 10. The one-way valve 70 is installed on the explosion suppressant delivery pipe 20, and its conduction direction is the flow direction of the explosion suppressant within the explosion suppressant delivery pipe 20. The switching valve 10 is installed on the explosion suppressant delivery pipe 20 and is used to open or close the explosion suppressant delivery pipe 20. The one-way valve 70 enables the explosion suppressant fluid to flow in one direction within the explosion suppressant delivery pipe 20, preventing backflow. The switching valve 10 can control the opening or closing of the explosion suppressant delivery pipe 20 according to actual needs, thereby achieving precise control of the explosion suppressant delivery.
