The fire extinguishing apparatus of the present application will be described with reference to the accompanying drawings.
Fig. 1 is a schematic structural view of a fire extinguishing apparatus according to an embodiment of the present application. For convenience of description, only the structures related to the present application are shown in the drawings.
Referring to fig. 1, a fire extinguishing apparatus 100 according to at least one embodiment of the present application includes a fire extinguishing container 10, a heat conducting member 30, a first fire extinguishing agent 21 and a second fire extinguishing agent 22, wherein the fire extinguishing container 10 is used for containing the heat conducting member 30, the first fire extinguishing agent 21 and the second fire extinguishing agent 22, and the first fire extinguishing agent 21 and the second fire extinguishing agent 22 are used for generating a fire extinguishing medium for extinguishing a flame in a protected space.
The fire extinguishing vessel 10 is of a cylindrical shape, and may have other shapes, such as a conical shape, a rectangular shape, etc., and the present application is not limited thereto. The fire extinguishing container 10 has a housing chamber 11 and a nozzle 12 communicating the housing chamber 11 with the outside, a first fire extinguishing agent 21 and a second fire extinguishing agent 22 are housed in the housing chamber 11, and the generated fire extinguishing agent is ejected from the nozzle 12 into the air of the protected space. The number of the spouts 12 may be at least two, for example, six, and six spouts 12 are opened at uniform intervals. Therefore, the spraying uniformity of the fire extinguishing medium can be improved, and the fire extinguishing efficiency and the fire extinguishing effect are improved. Further, the six nozzles 12 may be divided into a first nozzle 12 and a second nozzle 12, wherein the first nozzle 12 is dedicated to spraying the fire extinguishing medium generated by the first fire extinguishing agent 21, and the second nozzle 12 is dedicated to spraying the fire extinguishing medium generated by the second fire extinguishing agent 22. It is to be understood that the foregoing is illustrative only and is not to be construed as limiting the present application.
The heat conductive member 30 is disposed in the accommodating chamber 11 and partitions the accommodating chamber 11 into a first accommodating chamber 111 and a second accommodating chamber 112, and both the first accommodating chamber 111 and the second accommodating chamber 112 communicate with the outside through the nozzle 12. The first extinguishing agent 21 is contained in the first containing chamber 111, and the second extinguishing agent 22 is contained in the second containing chamber 112. Wherein the controlled combustion of the second extinguishing agent 22 may generate the second extinguishing medium, and the heat generated by the combustion may be transferred to the first extinguishing agent 21 by means of the heat conductive member 30, and the first extinguishing agent 21 may generate the first extinguishing medium when heated.
In actual use, when the fire extinguishing apparatus 100 is in use, that is, when a fire occurs, the second fire extinguishing agent 22 is combusted under control to generate a second fire extinguishing medium, heat released by combustion is conducted to the first fire extinguishing agent 21 through the heat conducting member 30, the first fire extinguishing agent 21 is heated to generate a first fire extinguishing medium, and the second fire extinguishing medium and the first fire extinguishing medium are discharged to the protected space through the nozzle 12 under pressure to extinguish the fire; in the non-use state, that is to say when no fire is occurring, the second extinguishing agent 22 does not burn and the first extinguishing agent 21 is likewise not activated without contact with heat. In this way, the fire extinguishing apparatus 100 generates high pressure only in the use state and does not generate high pressure in the non-use state, so that the safety of the fire extinguishing apparatus 100 can be effectively improved.
In order to avoid the mutual influence of the first extinguishing agent 21 and the second extinguishing agent 22, the heat conducting member 30 should be matched to the size of the accommodating chamber 11 and should divide the accommodating chamber 11 into a first accommodating chamber 111 and a second accommodating chamber 112, which are independent from each other, after being installed in the accommodating chamber 11. The heat conductive member 30 may be a metal heat conductive member 30, for example, a metal heat conductive member 30 made of a metal heat conductive material such as iron, copper, etc., so as to secure a heat conductive effect.
In some embodiments, the heat conductive member 30 includes a partition 31 and a heat conductive pipe 32. The partition 31 is provided in the accommodating chamber 11 and partitions the accommodating chamber 11 into a first accommodating chamber 111 and a second accommodating chamber 112. Specifically, the partition 31 has a plate shape, and is laterally placed in the housing chamber 11 to define a first housing chamber 111 and a second housing chamber 112. The heat conducting pipe 32 is coupled to the partition 31 and communicates the second accommodating chamber 112 with the nozzle 12, and the second fire extinguishing medium is transported from the second accommodating chamber 112 to the nozzle 12 via the heat conducting pipe 32 for spraying. Specifically, one end of the heat conduction pipe 32 is formed on the partition 31 and communicates with the second accommodation chamber 112, and the other end may be located in the first accommodation chamber 111 or may be formed on a chamber wall of the first accommodation chamber 111, that is, the spout 12 itself.
In actual use, the second fire extinguishing medium generated by burning the second fire extinguishing agent 22 in the second containing chamber 112 is transported from one end to the other end of the heat conducting pipe 32 located on the partition 31, and then sprayed out from the nozzle 12 and enters into the protected space for extinguishing fire. In addition, the second fire extinguishing medium may carry heat generated when the second fire extinguishing agent 22 burns during the transfer process in the heat transfer tube 32, and part of the heat may be transferred to the first fire extinguishing agent 21 through the tube wall of the heat transfer tube 32 and the air in the first containing chamber 111. Therefore, heat can be transferred to the first extinguishing agent 21 through the heat transfer pipe 32 excluding the partition 31, increasing a heat transfer path and a heat transfer area, thereby accelerating heat transfer and thus accelerating generation of the first extinguishing agent 21.
The heat pipes 32 may be in direct contact with the first extinguishing agent 21 or in indirect contact, in which embodiment at least part of the heat pipes 32 extend into the interior of the first extinguishing agent 21 to be in direct contact with the first extinguishing agent 21. In actual use, the heat carried in the heat conducting tube 32 can be directly transferred to the first extinguishing agent 21 through the wall of the heat conducting tube 32. In this way, the heat transfer rate to the first extinguishing agent 21 can be increased, and the heat transferred to the first extinguishing agent 21 can be increased, thereby increasing the generation of the first extinguishing medium by the first extinguishing agent 21.
To further enhance the heat conducting effect, the number of the heat conducting pipes 32 is at least two and are arranged at intervals. In particular, in some embodiments, the number of the heat conducting pipes 32 is six, the six heat conducting pipes 32 are uniformly arranged in the first accommodating cavity 111 in a penetrating manner at intervals, and the first fire extinguishing medium is arranged around the six heat conducting pipes 32. Therefore, the speed of heat transfer to the first extinguishing agent 21 can be further increased, and the heat transferred to the first extinguishing agent 21 is increased, so that the generation of the first extinguishing medium by the first extinguishing agent 21 is further accelerated.
It should be noted that, part of the heat carried by the second fire extinguishing medium is transferred to the first fire extinguishing medium through the wall of the heat conducting tube 32, so that the temperature of the second fire extinguishing medium sprayed out from the nozzle 12 can be reduced, and the second fire extinguishing medium is prevented from causing secondary damage to the personal and property in the protected space.
In some embodiments, the heat pipe 32 is straight or curved. The heat conduction area of the bent-tube-shaped heat conduction pipe 32 is increased as compared with that of the straight-tube-shaped heat conduction pipe 32, but the transmission speed of the fire extinguishing medium is correspondingly reduced. Accordingly, the shape of the heat conducting tube 32 is determined according to the actual use situation, and the present application is not limited thereto. In the embodiment of the present application, the heat pipe 32 has a straight tubular shape.
It should be appreciated that during actual use of the perfluoro-hexanone fire extinguishing apparatus 100, when the protection space is too large or narrow and high, the fire extinguishing agent cannot completely extinguish the fire in the protection space, which may lead to an immeasurable risk. Because the boiling point of the perfluorinated hexanone extinguishing agent is low, when the perfluorinated hexanone extinguishing device 100 is started, vaporized or atomized perfluorinated hexanone is sprayed, and the density of the vaporized or atomized perfluorinated hexanone is greater than that of air, so that the perfluorinated hexanone extinguishing agent can be always suspended in the lower layer area of the protection space. When the perfluorohexanone fire extinguishing apparatus 100 is applied to an excessively large or narrow and high protection space, the perfluorohexanone fire extinguishing agent may not extinguish the flames in the upper region, resulting in immeasurable consequences.
To alleviate the problem of flame failure in the upper zone, applicants have found that the dosage of the perfluorinated hexanone extinguishing agent can be increased. However, if the amount of the fire extinguishing agent is increased, the cost of the fire extinguishing apparatus 100 is increased, and at the same time, it is difficult to push out a large amount of fire extinguishing agent from the viewpoint of structural design, and there may be a problem that the residual rate of the fire extinguishing agent is excessively high.
In view of this, in some embodiments, the density of the first extinguishing medium is less than the air density and the density of the second extinguishing medium is greater than or equal to the air density. In actual use, after the device is started, the first fire extinguishing agent 21 and the second fire extinguishing agent 22 can respectively generate a first fire extinguishing medium and a second fire extinguishing medium, and the first fire extinguishing medium and the second fire extinguishing medium are sprayed into the air of the protected space through the nozzles 12. Because the density of the first fire extinguishing medium is smaller than that of air, under the disturbance of high temperature and hot air in a fire scene, the first fire extinguishing medium moves towards the upper layer area of the protection space and extinguishes upper layer flames; since the density of the second extinguishing medium is greater than or equal to the air density, the second extinguishing medium may spread in the lower region of the protected space and extinguish the lower flame. In this way, the first fire extinguishing medium and the second fire extinguishing medium respectively permeate the upper layer area and the lower layer area of the protection space, and extinguish flames in the corresponding areas, so that the fire extinguishing medium can be used for the oversized or narrow and high protection space.
It should be noted that the fire extinguishing apparatus 100 is used not only for the purpose of illustration, but also for the purpose of protecting the space in other scenes, and the present application is not limited thereto.
In some embodiments, the first extinguishing agent 21 is liquid perfluorinated hexanone, the first extinguishing medium produced by the initiation is gaseous perfluorinated hexanone, the second extinguishing agent 22 is an aerosol generating agent, and the second extinguishing medium produced by the controlled combustion is an aerosol extinguishing medium, the gaseous perfluorinated hexanone and the aerosol extinguishing medium are both ejected from the nozzle 12 into the ambient air.
In actual use, the aerosol generating agent burns to generate aerosol fire extinguishing medium and generates a large amount of heat, and the perfluoro-hexanone is vaporized into gaseous perfluoro-hexanone. After the aerosol fire-extinguishing medium and the gaseous perfluorinated hexanone are sprayed into the air in the protection space through the spray nozzles 12, the aerosol fire-extinguishing medium with the density smaller than that of the air moves to the upper layer area of the protection space so as to extinguish the upper layer flame, and the gaseous perfluorinated hexanone with the density larger than that of the air moves to the lower layer area of the protection space so as to extinguish the lower layer flame. Therefore, fire extinguishing medium is diffused in the upper and lower layer areas of the protection space, so that flames in the space can be completely extinguished, and loss expansion is prevented.
It can be understood that, compared with the mode that the liquid perfluorinated hexanone in the pressure storage type fire extinguishing device 100 is pushed into the protection space by pressure, the non-pressure storage type fire extinguishing device 100 in the embodiment of the application utilizes the heated and vaporized liquid perfluorinated hexanone to be gaseous perfluorinated hexanone and then ejected into the protection space, so that the residual rate of perfluorinated hexanone in the fire extinguishing device 100 can be effectively reduced.
In some embodiments, the fire suppression apparatus 100 further comprises an activation device 40 coupled to the second fire suppression agent 22, the activation device 40 being configured to detect a fire and to select whether to ignite the second fire suppression agent 22 based on the fire. Specifically, the starting device 40 includes one of a heat-sensitive wire and an electronic ignition head, and may be a combination of a heat-sensitive wire and an electronic ignition head.
In particular, in an embodiment of the present application, the activation device 40 comprises a heat-sensitive wire having one end disposed in a protected space outside the fire-extinguishing container 10 and the other end passing through the fire-extinguishing container 10 to be connected with the aerosol generating agent. In actual use, when a fire occurs in the protected space, the heat sensitive wire burns and ignites the second extinguishing agent 22, causing it to produce a second extinguishing medium. At the same time, the heat generated by the combustion activates the first extinguishing agent 21, causing it to generate the first extinguishing medium. The second extinguishing medium and the first extinguishing medium are then rapidly sprayed under pressure from the nozzles 12 towards the protected space to extinguish the flames in the protected space.
In the above fire extinguishing apparatus 100, when in use, that is, when a fire occurs, the second fire extinguishing agent 22 is burned under control to generate a second fire extinguishing medium, the heat released by the combustion is conducted to the first fire extinguishing agent 21 through the heat conducting member 30, the first fire extinguishing agent 21 is heated to generate a first fire extinguishing medium, and the second fire extinguishing medium and the first fire extinguishing medium are discharged to the protected space through the nozzle 12 under pressure to extinguish the fire; in the non-use state, that is to say when no fire is occurring, the second extinguishing agent 22 does not burn and the first extinguishing agent 21 is not started without heat contact. In this way, the fire extinguishing apparatus 100 generates high pressure only in the use state and does not generate high pressure in the non-use state, so that the safety of the fire extinguishing apparatus 100 can be effectively improved.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples illustrate only a few embodiments of the application, which are described in detail and are not to be construed as limiting the scope of the claims. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the application, which are all within the scope of the application. Accordingly, the scope of protection of the present application is to be determined by the appended claims.
