Description

Technical Field

[0001] This utility model relates to the field of fire-fighting devices, and more specifically, to a fire extinguishing and explosion suppression bottle. Background Technology

[0002] Currently, most new fire extinguishing explosion suppression bottles in China use perfluorohexanone as the explosion suppressant. While perfluorohexanone is environmentally friendly, its fire extinguishing performance is inferior to that of Halon 1301 explosion suppressant, meaning that more explosion suppressant is required in the same space. For traditional pressurized fire extinguishing explosion suppression bottles, the spraying speed is relatively slowed during spraying, and the extended discharge time results in poor explosion suppression performance. Utility Model Content

[0003] The purpose of this utility model is to provide a fire extinguishing and explosion suppression bottle to solve the problem of poor explosion suppression performance of existing fire extinguishing and explosion suppression bottles. To solve the above technical problem, this utility model provides a fire extinguishing and explosion suppression bottle, comprising: a bottle body having a gas inlet and a gas outlet; a first diaphragm sealed at the gas inlet; a second diaphragm sealed at the gas outlet; a gas generating device disposed on the bottle body, the gas generating device including a gas generating ignition module and a gas generating module, the gas generating ignition module controlling the gas generating module to generate gas according to an electrical signal, the gas outlet of the gas generating device being opposite to the first diaphragm; and a guide plate disposed on the bottle body and opposite to the second diaphragm.

[0004] By adopting the above technical solution, this utility model has the following beneficial effects:

[0005] Applying the technical solution of this utility model, when the gas-generating ignition module receives a signal, it activates the gas-generating module. The gas-generating module generates high-temperature, high-pressure gas that ruptures the first diaphragm. The high-temperature, high-pressure gas generated by the gas-generating module rushes into the pressurized bottle body. The gas (high-temperature, high-pressure gas) and liquid (explosion suppressant) inside the bottle body form a two-way gas-liquid flow, increasing the contact area between the gas and liquid. Because the explosion suppressant has a low boiling point, the high-temperature, high-pressure gas generated by the gas-generating device causes the explosion suppressant to vaporize instantly, thus forming a high-pressure explosion suppressant gas inside. When the critical point of the second diaphragm destruction is reached, the second diaphragm bursts. The explosion suppressant is sprayed from the gas outlet onto the guide plate, allowing the explosion suppressant to diffuse evenly and efficiently throughout the space, improving the overall explosion suppression performance. The fire extinguishing explosion suppressant bottle with the above structure has the following advantages: First, to improve the discharge speed, this utility model uses the internal pressure storage and an external gas-generating device to generate high-temperature, high-pressure gas, causing the explosion suppressant to be instantly atomized and sprayed out, greatly improving the spray speed and vaporization efficiency, directly eliminating the collision atomization process and directly vaporizing. Secondly, the fire extinguishing and explosion suppression bottle of this invention has strong environmental adaptability. Specifically, in low-temperature environments, the internal pressure of pressurized bottles in existing technologies decreases, affecting the discharge rate and explosion suppression effect. However, the fire extinguishing and explosion suppression bottle of this invention is a hybrid-type pressure-storing explosion suppression bottle with a built-in gas generating device that can generate high-temperature and high-pressure gas internally. Therefore, even in low-temperature environments, it will not affect normal discharge and explosion suppression performance. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] The present invention will be further explained below with reference to specific embodiments.

[0021] like Figures 1 to 3 As shown, the fire extinguishing and explosion suppression bottle of Embodiment 1 includes: a bottle body 10, a first diaphragm 20, a second diaphragm 30, a gas generating device 40, and a flow guide plate 50. The bottle body 10 has a gas inlet 11 and a gas outlet 12; the first diaphragm 20 is sealed at the gas inlet 11; the second diaphragm 30 is sealed at the gas outlet 12; the gas generating device 40 is disposed on the bottle body 10, and includes a gas generating ignition module 41 and a gas generating module 42. The gas generating ignition module 41 controls the gas generating module 42 to generate gas according to an electrical signal, and the gas outlet 43 of the gas generating device 40 is opposite to the first diaphragm 20; the flow guide plate 50 is disposed on the bottle body 10 and is opposite to the second diaphragm 30.

[0022] Applying the technical solution of Embodiment 1, when the gas generation ignition module 41 receives a signal, it activates the gas generation module 42. The gas generation module 42 generates high-temperature, high-pressure gas that ruptures the first diaphragm 20. The high-temperature, high-pressure gas generated by the gas generation module 42 rushes into the pressurized bottle body 10. The gas (high-temperature, high-pressure gas) and liquid (explosion suppressant) inside the bottle body 10 form a bidirectional gas-liquid flow, increasing the contact area between the gas and liquid. Because the explosion suppressant has a low boiling point, the high-temperature, high-pressure gas generated by the gas generation device 40 causes the explosion suppressant to vaporize instantly, thus forming a high-pressure explosion suppressant gas inside. When the critical point for the second diaphragm 30 to break is reached, the second diaphragm 30 bursts. The explosion suppressant is sprayed from the gas outlet 12 onto the guide plate 50, allowing the explosion suppressant to diffuse evenly and efficiently throughout the space, improving the overall explosion suppression performance. The fire extinguishing and explosion suppression bottle with the above-described structure has the following advantages: First, in order to improve the discharge rate, this embodiment uses the internal pressure storage and an external gas generating device to produce high-temperature and high-pressure gas, causing the explosion suppressant to be instantly atomized and sprayed out, greatly improving the spray speed and vaporization efficiency, directly eliminating the collision atomization process and directly vaporizing. Second, the fire extinguishing and explosion suppression bottle of this embodiment has strong environmental adaptability. Specifically, in low-temperature environments, the internal pressure of pressurized bottles in existing technologies decreases, affecting the discharge rate and explosion suppression effect. However, the fire extinguishing and explosion suppression bottle of this embodiment is a hybrid pressure storage type explosion suppression bottle with a built-in gas generating device that can generate high-temperature and high-pressure gas internally. Therefore, even in low-temperature environments, it will not affect normal discharge and explosion suppression performance.

[0023] like Figure 3 and Figure 4 As shown, in Embodiment 1, the gas outlet 43 of the gas generating device 40 and the gas inlet 11 of the bottle body 10 have gas acceleration structures. Specifically, when the high-temperature and high-pressure gas produced by the gas generating device 40 breaks the first diaphragm 20, the high-temperature and high-pressure gas is accelerated into the pressurized bottle body 10 under the acceleration of the gas acceleration structure, increasing the contact between the gas and the liquid, causing the explosion suppressant to vaporize instantly, further improving the vaporization efficiency, and thus further improving the explosion suppression effect.

[0024] like Figure 3 and Figure 4As shown, in Embodiment 1, the gas outlet 43 of the gas generating device 40 has a first constricted section 431 that contracts inward from top to bottom, and the gas inlet 11 of the bottle body 10 has a first flared section 111 that expands outward from top to bottom. The maximum cross-sectional area of ​​the first flared section 111 is less than the maximum cross-sectional area of ​​the first constricted section 431. The first constricted section 431 and the first flared section 111 form a gas acceleration structure. Specifically, the first constricted section 431 and the first flared section 111 constitute a Laval structure. When gas enters the gas passage of the Laval structure, it can be effectively accelerated, thereby achieving the purpose of improving gasification efficiency. In the above structure, the gas acceleration structure is composed of the gas generating device 40 and the bottle body 10 itself, eliminating the need for other components, thus reducing the number of components and lowering production costs.

[0025] like Figures 2 to 4 As shown, in Embodiment 1, the bottle body 10 includes a container 13 with an opening at the top and a cap 14 covering the opening. The cap 14 has a downwardly recessed step 141, and a gas inlet 11 is provided on the step 141. A gas generating device 40 is mounted on the step 141, and a first diaphragm 20 is sandwiched between the gas outlet 43 of the gas generating device 40 and the step surface of the step 141. In the above structure, part of the step 141 constitutes both a gas acceleration structure and an installation structure for the gas generating device 40, thereby simplifying the components and reducing production costs.

[0026] In Example 1, the bottle body 10 contains a burst suppressant, which is perfluorohexanone. This burst suppressant has low toxicity to humans.

[0027] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, in Embodiment 1, the guide plate 50 includes an impact plate 51 and a plurality of guide ribs 52 spaced apart along the circumferential direction of the impact plate 51, with a guide gap formed between adjacent guide ribs 52. This structure makes the guide plate 50 a cage-type water distribution plate, which can uniformly diffuse the ejected high-explosive suppressant. This allows the suppressant to diffuse evenly and efficiently throughout the space, improving the overall explosion suppression performance.

[0028] like Figure 6 As shown in Embodiment 1, the extension line of the guide rib 52 projected onto the impact plate 51 is extension line L1, and the line connecting the outer end of the guide rib 52 to the midpoint of the impact plate 51 is connecting line L2. The extension line L1 of each guide rib 52 is located on the same side of its corresponding connecting line L2. That is, each guide rib 52 is eccentrically arranged, so that the explosion suppressant sprayed from the guide rib 52 forms a high-speed swirling flow, realizing that the explosion suppressant is evenly and quickly distributed throughout the entire space.

[0029] like Figure 6 As shown, in Embodiment 1, the angle between the extension line L1 and the connecting line L2 of each guide rib 52 is equal. This structure results in a better swirling diffusion effect.

[0030] like Figure 5 and Figure 6 As shown, in Embodiment 1, a cone 53 is provided on the surface of the impact disc 51 near the gas outlet 12 of the bottle body 10. This structure can buffer and diffuse the ejected high-pressure detonator, achieving uniform and rapid distribution of the detonator throughout the space.

[0031] The difference between the fire extinguishing and explosion suppression bottle in Example 2 and the fire extinguishing and explosion suppression bottle in Example 1 lies only in the specific structure of the gas acceleration structure. Specifically, as shown in the example... Figure 7 As shown, in Embodiment 2, the outlet 43 of the gas generating device 40 has a second constriction section 432 and a second flaring section 433 from top to bottom. The maximum cross-sectional area of ​​the second flaring section 433 is smaller than the maximum cross-sectional area of ​​the second constriction section 432. The second constriction section 432 and the second flaring section 433 form a gas acceleration structure. Specifically, the second constriction section 432 and the second flaring section 433 constitute a Laval structure. When gas enters the gas passage of the Laval structure, it can be effectively accelerated, thereby achieving the purpose of improving gasification efficiency. In the above structure, the gas acceleration structure is composed of the gas generating device 40 itself and the bottle body 10, eliminating the need for other components, thus reducing the number of components and lowering production costs.

[0032] The difference between the fire extinguishing and explosion suppression bottle in Example 3 and the fire extinguishing and explosion suppression bottle in Example 1 lies only in the specific structure of the gas acceleration structure. Specifically, as shown in the example... Figure 8 As shown, in Embodiment 3, the gas inlet 11 of the bottle body 10 has a third constriction section 112 and a third flaring section 113 from top to bottom. The maximum cross-sectional area of ​​the third flaring section 113 is smaller than the maximum cross-sectional area of ​​the third constriction section 112. The third constriction section 112 and the third flaring section 113 form a gas acceleration structure. Specifically, the third constriction section 112 and the third flaring section 113 constitute a Laval structure. When gas enters the gas passage of the Laval structure, it can be effectively accelerated, thereby achieving the purpose of improving gasification efficiency. In the above structure, the gas acceleration structure is composed of the gas generating device 40 and the bottle body 10 itself, eliminating the need for other components, thus reducing the number of components and lowering production costs.

[0033] The difference between the fire extinguishing and explosion suppression bottle in Example 4 and the fire extinguishing and explosion suppression bottle in Example 1 lies only in the specific structure of the gas acceleration structure. Specifically, in Example 4, a gas acceleration wheel (not shown in the figure) is provided at the gas outlet 43 of the gas generating device 40 and the gas inlet 11 of the bottle body 10, forming a gas acceleration structure. Specifically, the gas acceleration wheel is installed at the gas inlet 11 via a shaft. When high-temperature and high-pressure gas enters the gas inlet 11 of the bottle body 10, the airflow impacts the gas acceleration wheel, which drives the gas acceleration wheel to rotate on the shaft, forming an automatic force acceleration, circulating and accelerating the airflow, thereby achieving the purpose of improving gasification efficiency. It should be noted that the gas acceleration wheel in this embodiment can be like the automatic force acceleration wheel disclosed in patent CN116428443A, or it can be any acceleration wheel capable of accelerating the gas in the air duct.

[0034] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0035] 1. High-efficiency vaporization. Specifically, the internal gas generating device produces high-temperature and high-pressure gas that breaks the diaphragm (first diaphragm) of the isolation container. The high-temperature and high-pressure gas is accelerated into the pressurized container chamber (bottle body) through the Laval gas channel. The gas and liquid form a two-way flow, increasing the contact between the gas and liquid, causing the explosion suppressant to vaporize instantly. Therefore, a high-pressure explosion suppressant gas is formed inside. When the critical point of the external explosion diaphragm (second diaphragm) is reached, the explosion diaphragm bursts open, and the agent is sprayed out from the nozzle.

[0036] 2. Rapid diffusion. Specifically, the cage-type water distribution plate buffers the ejected high-pressure explosive agent and diffuses it evenly and efficiently throughout the space, improving the explosion suppression performance.

[0037] 3. Strong environmental adaptability. Specifically, the fire extinguishing and explosion suppression bottle in this embodiment is a hybrid storage pressure explosion suppression bottle with a built-in gas generating agent device that generates high-temperature and high-pressure gas inside. Low-temperature environments will not affect its normal release and explosion suppression performance.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model 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 or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
