Description

  The present invention relates to a fire extinguishing system suitable for a general fire (A fire) in which paper, wood, fiber, etc. burns, and in particular, for buildings such as important cultural properties listed in Appendix 1 (17) of the Fire Service Law Enforcement Examples. The present invention relates to a fire extinguishing system suitable for fire extinguishing.

  As a general fire extinguishing facility, a fire extinguishing facility that pumps water from a water source and discharges water to an object to be extinguished to extinguish the fire is widely known (for example, see Patent Document 1). Buildings made of paper, wood, and fiber are fast-fired, and therefore require a fast extinguishing speed. In addition, in buildings such as important cultural properties listed in Appendix 1 (17) of the Fire Service Law Enforcement Example, in order to minimize loss due to water exposure, the fire can be extinguished with a small amount of water. It is demanded.

  Conventionally, as a fire extinguishing agent that can be extinguished quickly and in a small amount with respect to a general fire, a fire extinguishing agent in which an infiltrant is mixed with water is known (for example, see Patent Document 2). In the case of fire extinguishing activities using a fire-extinguishing agent mixed with water, prepare a fire-extinguishing agent in which water and infiltrating agent are mixed at a predetermined ratio in advance, and transport this fire-extinguishing agent to the fire site to extinguish the fire. A fire extinguisher is filled in a fire extinguisher, and fire extinguishing such as radiating in a fire is performed (for example, see Patent Document 3).

JP-A-5-231172 JP 2000-60990 A JP 2012-139513 A

  As described above, in extinguishing activities using a conventional fire-extinguishing agent mixed with water, we prepared a fire-extinguishing agent in which water and infiltrant were mixed in a predetermined ratio and transported this fire-extinguishing agent to the fire site. The fire is extinguished or the fire extinguisher is filled in a fire extinguisher and radiated in the event of a fire. For this reason, in the former, there is a problem that transportation may be difficult depending on the location of the fire, and it is impossible to respond quickly to the fire, and it is difficult to handle when the fire extinguishing agent is insufficient. In the latter case, there is a problem that even if it can cope with an initial fire, it cannot cope with a large-scale fire.

  An object of the present invention is to provide a fire extinguishing system capable of discharging a necessary amount of mixed water of water and a wetting agent regardless of the location and scale of a fire.

(1) In order to achieve the above object, a fire extinguishing system according to the present invention includes a fire-fighting pump device provided with a fire-extinguishing water pressure feed line, and an infiltrant storage container. An infiltrant mixing device that sucks the infiltrant stored in the infiltrant storage container and mixes it with the water passing through the fire-extinguishing water pressure feed line, so that the mixed water of the water and the infiltrant is discharged from the discharge nozzle to the fire extinguishing object. It is configured.

  According to the fire extinguishing system of (1) above, water and a wetting agent can be mixed at the fire site and released to the fire extinguishing target. If the infiltrant storage container is replenished with the infiltrant, it becomes possible to discharge a necessary amount of water and the infiltrant mixed water regardless of the location and scale of the fire. Therefore, if the fire extinguishing system of (1) is applied to a hand pump car, a fire engine, a building, etc., a fire extinguishing agent is prepared in advance and transported to the fire site like conventional fire extinguishing activities, or Eliminates the need to fill the fire extinguisher. Furthermore, the fire extinguishing system of the above (1) can extinguish a general fire by the same operation as a conventional fire extinguishing activity of drawing water from a water source and releasing it to a fire extinguishing target.

(2) Preferably, in the fire extinguishing system of (1), the fire pump device includes a water discharge pump that pumps water pumped up from a water source, and the infiltrant mixing device is water that is pumped to the water discharge pump. It is good to make it the structure which mixes the said infiltrant with the quantity of water according to the quantity of the water driven by the flow of this, and pumped to the said water discharge pump.

  According to the fire extinguishing system of (2) above, first, since the infiltrant mixing device is driven by the flow of water pumped to the water discharge pump, a drive source for the infiltrant mixing device is not necessary. Secondly, the infiltrant and water are always mixed at a constant mixing ratio even when the amount of water pumped to the water discharge pump changes. That is, in the fire extinguishing system of (2) above, mixed water having a preset mixing ratio is obtained instantaneously, and no time is required until the mixing ratio is stabilized.

(3) Preferably, in the fire extinguishing system according to (1) or (2), the infiltrant mixing device is driven by a pump turbine driven by a flow of water pumped to the water discharge pump, and driven by the pump turbine. An infiltrant pump for sucking the infiltrant in an amount corresponding to the amount of water pumped to the discharge pump from the infiltrant storage container, and means for transmitting the driving force of the pump turbine to the infiltrant pump. It is good to include it.

  According to the fire extinguishing system of (3) above, a dedicated drive source is not required for the pump turbine and the infiltrant pump. As a result, in the fire extinguishing system having all the configurations (1) to (3), the infiltrant mixing device is driven only by the flow of water pumped from the water source, and is always constant immediately after the start of driving. The mixed water of the mixing ratio is discharged.

(4) Preferably, in the fire extinguishing system of (3), the pump turbine may be a vane pump that is driven by a flow of water pumped to the water discharge pump.

  In the fire extinguishing system of (4) above, the vane pump as a pump turbine is driven only by the flow of water pumped up from the water source. When the configuration of (2) is provided, the driving force of the pump turbine is transmitted to the infiltrant pump, and the infiltrant pump is interlocked with the vane pump. Thereby, an infiltrant pump sends out the amount of infiltrant according to the amount of water pumped to the vane pump, and mixes it with water.

(5) Preferably, in the fire extinguishing system according to any one of the above (1) to (4), the infiltration agent pump is interlocked with the pump turbine and the amount of the infiltration according to the amount of water pumped to the pump turbine. It is good to set it as the structure provided with the piston pump which attracts | sucks an agent from the said infiltration agent storage container.

  In the fire extinguishing system of (5) above, the piston pump as the infiltrant mixing device sucks the amount of infiltrant according to the amount of water pumped to the pump turbine from the infiltrant storage container, and the mixing ratio of the infiltrant and water Always keep constant.

(6) Preferably, in the fire extinguishing system according to any one of the above (1) to (5), the fire extinguishing target is an important cultural property, an important tangible folk cultural property, a historic site, It may be a building that has been designated as an important cultural property or certified as an important work of art by the provisions of the Act on the Preservation of Old Important Works.

  As described above, any of the fire extinguishing systems (1) to (5) described above can mix water and a wetting agent at a fire site and discharge them to a fire extinguishing target. The mixed water of water and infiltrant is effective for general fires where paper, wood, fibers, etc. burn, and is particularly suitable for extinguishing buildings such as the important cultural property mentioned in (6) above. That is, in the fire extinguishing system of (1) to (5), if the infiltrant storage container is supplemented with the infiltrant, the necessary amount of water and infiltrant mixed water is discharged regardless of the location and scale of the fire. It is the most effective fire prevention equipment for relieving buildings such as the important cultural property listed in (6) from fire damage.

  According to the fire extinguishing system of the present invention, it is possible to mix the infiltrant with the water pumped up from the water source and discharge it to the fire extinguishing object. That is, there is no need to transport a fire extinguishing agent prepared in advance to the fire site. Further, by replenishing the infiltrant storage container with the infiltrant, it is possible to release a necessary amount of the mixed water of the water and the infiltrant regardless of the scale of the fire. Furthermore, the fire extinguishing system of the present invention can extinguish a general fire by pumping water from a water source and releasing it to a fire extinguishing target, similarly to conventional fire extinguishing activities.

It is the schematic which shows the fire extinguishing system which concerns on 1st embodiment of this invention. It is the schematic which shows the fire extinguishing system which concerns on 2nd embodiment of this invention.

<First embodiment>
Hereinafter, the fire extinguishing system which concerns on 1st embodiment of this invention is demonstrated with reference to FIG.

  The fire extinguishing system 1 of this example is provided with the infiltrant storage container 4 in the fire fighting pump device 3 provided with the fire-extinguishing water pressure feed line 2, and the fire extinguishing water pressure feed line 2 has the infiltration stored in the infiltrant storage container 4. An infiltrant mixing device 5 for sucking the agent and mixing it with water passing through the fire-extinguishing water pressure feed pipe 2 is provided, and the mixed water of the water and the infiltrant is discharged from the water discharge nozzle 6.

  In the fire-fighting pump device 3, in this example, a pumping pump 7 and a water discharge pump 8 are provided, and a fire-extinguishing water pressure feed line 2 is connected to the secondary side of the water discharge pump 8. A pumping hose 9 is connected to the pumping pump 7, and water is pumped from the water source 10 by driving the pumping pump 7. Further, a water discharge hose 11 is connected to the fire-extinguishing water pressure feed line 2, and water pumped up by the pump 7 by driving the water discharge pump 8 is pumped to the water discharge hose 11 through the fire-extinguishing water pressure feed line 2. 11 is configured to discharge water from a water discharge nozzle 6 provided at the tip of 11.

  The infiltrant mixing device 5 that is provided in the fire-extinguishing water pressure supply line 2 and sucks the infiltrant stored in the infiltrant storage container 4 and mixes it with the water passing through the fire-extinguishing water pressure supply line 2 is stored in the infiltration agent storage container 4. It is not particularly limited as long as the infiltrant can be sucked in and mixed with water passing through the fire-extinguishing water pressure feed line 2 at a predetermined mixing ratio. For example, it is used in a foam fire-extinguishing chemical mixing system of a foam fire-extinguishing equipment. Can be used.

In addition, in the infiltrant stored in the infiltrant storage container 4, conventionally known infiltrant added to the fire extinguishing agent is used, and as typical chemical substances that become the infiltrant, ammonium phosphate, ammonium sulfate Etc. Moreover, the mixing rate of the infiltrating agent mixed with the water passing through the fire-extinguishing water pressure feed line 2 is conventionally mixed at the same mixing rate as the infiltrating agent added to the extinguishing agent.
The fire extinguishing system 1 configured as described above is provided in a fire engine and is installed near a building or the like.

  According to the fire extinguishing system 1 configured as described above, the water pumped up by the pump 7 by driving the discharge pump 8 passes through the fire-extinguishing water pressure feed line 2 connected to the secondary side of the discharge pump 8. Mixing with the infiltrant sucked from the infiltrant storage container 4 by the infiltrant mixing device 5 provided in the fire-extinguishing water pressure feed line 2, and mixing the water and the infiltrant from the water discharge nozzle 6 provided at the tip of the water discharge hose 11 As the mixed water is discharged, the fire extinguishing ability is improved, the fire extinguishing time can be shortened and the amount of water used can be reduced, and it is effective for construction that is constructed from paper, wood, fiber, etc. It is especially suitable for extinguishing cultural assets.

  In addition, the fire extinguishing system according to the present invention can be carried out only by providing a conventional fire extinguishing equipment for general fires with an infiltrant storage container, and providing an infiltrant mixing device in the water supply pipeline for fire extinguishing. Regardless of the situation, it is possible to release the required amount of mixed water in which wetting agent is mixed with water, and since it can be performed in the same way as conventional fire extinguishing activities, it is affected by the environment of the fire site. No fire extinguishing activities can be performed easily.

<Second embodiment>
Next, the fire extinguishing system which concerns on 2nd embodiment of this invention is demonstrated with reference to FIG. In this embodiment, the specific structure of the infiltrant mixing apparatus 5 mentioned above is illustrated. In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The fire extinguishing system 1 according to the present embodiment includes a wetting agent mixing device 5 having a configuration shown in FIG. The infiltrant mixing device 5 mainly includes a pump turbine 51, a coupling 52, and an infiltrant pump 53. As surrounded by a thin line in the figure, the pump turbine 51, the coupling 52, and the infiltrant pump 53 form a mechanically integrated structure to constitute the infiltrant mixing device 5. The infiltrant mixing device 5 is connected to the water discharge pump 8, the infiltrant storage container 4 and the water discharge nozzle 6 via a pipe line and a hose.

  Here, the pipe line and the hose used for connection with the infiltrant mixing device 5 are not particularly limited as long as liquid can pass through. The water source 10 and the infiltrant storage container 4 are not particularly limited as long as they can always store water or the infiltrant. That is, the water source 10 and the infiltrant storage container 4 need not be water sources or storage containers designed exclusively for the infiltrant mixing device 5. For example, it is possible to apply an existing water source or storage container provided near the place where the fire extinguishing object or the infiltrant mixing device 5 is installed.

  As the pump turbine 51 of this embodiment, a vane pump is used, for example. The inlet of the pump turbine 51 is connected to the water discharge pump 8 via the fire-extinguishing water pressure feed line 2. On the other hand, the outlet of the pump turbine 51 is connected to the water discharge nozzle 6 via the water discharge hose 11. The pump turbine 51 that is a vane pump is driven by the flow of water supplied from the water discharge pump 8. The speed at which the pump turbine 51 rotates is proportional to the volume flow rate of water supplied from the water discharge pump 8. The flow of the water pumped up from the water source 10 and pumped to the pump turbine 51 is indicated by a hollow single arrow in FIG.

  On the other hand, a piston pump is used for the infiltrant pump 53 of this embodiment, for example. The infiltrant pump 53 includes a piston that is driven by a rotating shaft (not shown) (see the small white double arrow in FIG. 2). The rotating shaft of the infiltrant pump 53 is coupled to the rotating shaft of the pump turbine 51 via the coupling 52. With this configuration, the infiltrant pump 53, which is a piston pump, works in conjunction with the pump turbine 51 and sucks an amount of infiltrant according to the amount of water pumped to the pump turbine 51 from the infiltrant storage container 4. As a result, an amount of the infiltrant according to the amount of water pumped to the pump turbine 51 is mixed with water. The flow of the infiltrant that is sucked from the infiltrant storage container 4 and mixed with the water that is pumped to the pump turbine 51 is indicated by the sanitized arrows in FIG. The mixed water of water and the infiltrant is discharged from the water discharge nozzle 6 to a fire extinguishing object (not shown).

  The above-described infiltrant mixing device 5 of the present embodiment is driven by the flow of water supplied from the water discharge pump 8, and has an effect that the infiltrant and water are always mixed at a constant mixing ratio. First, the pump turbine 51 is driven by the flow of water supplied from the water discharge pump 8, and the infiltrant pump 53 is interlocked with this driving force. Therefore, a dedicated drive source is not required for the pump turbine 51 and the infiltrant pump 53. Second, even when the amount of water pumped to the pump turbine 51 changes, the infiltrant and water are always mixed at a constant mixing ratio. That is, in the infiltrant mixing device 5 of the present embodiment, mixed water having a preset mixing ratio is obtained instantaneously, and no time is required until the mixing ratio is stabilized. As a result, immediately after the infiltrant mixing device 5 starts driving, mixed water having a constant mixing ratio is always discharged.

  Here, the user of the fire extinguishing system 1 can freely set the mixing ratio of the water and the infiltrant in consideration of the nature of the fire extinguishing target. The mixing ratio of the infiltrant with respect to water is preferably 20 to 50%, for example. Moreover, as an infiltrating agent, for example, one or both of an ammonia salt of methyl phosphate ester and an ammonium adduct of a phosphoric acid reaction solution of monoethanolamine can be applied.

By adding the wetting agent having the above composition to water at the above mixing ratio, firstly, since it contains a large amount of water, a large latent heat of evaporation can be generated, and a cooling effect on combustible materials is exhibited. Secondly, special phosphates contained in the infiltrant are thermally decomposed, and a film is formed on the surface of the combustible material. Thereby, the supply of oxygen to the combustible material is interrupted, and the propagation of radiant heat is prevented. Thirdly, due to the dehydration action of phosphorous oxide (P ₂ O ₅ ) at a high temperature, the combustible material can be made flame-retardant, and the combustible material is prevented from reburning. Fourth, incombustible or incombustible gas is generated in the process of thermal decomposition of special phosphates. This non-flammable or flame-retardant gas, which is an intermediate product, exhibits an oxidation chain reaction, that is, a negative catalytic effect (suppressing extinguishing) that interrupts the continuation of combustion. Furthermore, the nonflammable or flame retardant gas also has an effect of diluting a flammable gas such as oxygen.

<Application of fire extinguishing system>
As described above, the fire extinguishing systems of the first and second embodiments can mix water and a wetting agent at the fire site and release them to the fire extinguishing target. The mixed water of water and infiltrant is effective for general fires where paper, wood, fibers, etc. burn, especially for buildings such as important cultural properties listed in Appendix 1 (17) of the Fire Service Law Enforcement Examples. Suitable for fire fighting. That is, in the fire extinguishing system according to the first and second embodiments, when the infiltrant storage container 4 is supplemented with the infiltrant, the necessary amount of water and infiltrant mixed water is discharged regardless of the location and scale of the fire. It is the most effective fire protection equipment for relieving buildings such as important cultural properties from fire damage.

<Other changes>
The fire extinguishing system of the present invention, the fire pump device and the infiltrant mixing device constituting the fire extinguishing system are not limited to the configurations of the first and second embodiments described above. For example, the pumps for pumping and discharging are not limited to the two pumps 7 and 8. It is good also as a structure which performs pumping and discharging with a single pump, or it is good also as a structure which performs pumping and discharging with three or more pumps. Moreover, the fire extinguishing system of this invention can be implemented with the form of the hand pump vehicle which installed the fire pump apparatus 3 in the trolley | bogie. By adopting the form of a hand pump car, mobility to the fire site is enhanced. In addition, the water source used for the fire extinguishing system of the present invention is not particularly limited. For example, in addition to artificial fire prevention water tanks such as fire water, water storage tanks and fire hydrants, infinite water use such as rivers and ponds may be used.
