Description

Fire control method and fire control chemical radiator

The present invention relates to a fire control method and a fire control chemical radiator for preventing an artificial fire such as arson terrorism and for preventing the spread of fire.

Artificial fires such as arson terrorism caused by a person intentionally sprinkling a flammable liquid such as gasoline or kerosene to ignite a fire are difficult to prevent, especially fueled. If it is ignited later and after a lapse of time, not only will it explode and burn, but it will be extremely difficult to extinguish the fire after ignition.
It is desired to effectively control fires in advance even for unintentional combustibles (combustibles that have leaked or spread due to an accident or carelessness).

Therefore, a method has been proposed in which a nozzle that radiates the chemical in a fan shape is used to adhere the chemical to a combustible material (for example, a wall of a cultural property) with a thickness that has an effect of preventing the spread of fire without a gap to prevent the spread of fire.

Further, it is preferable to use a fire suppressant 99 that is sprayed (radiated) in the form of bubbles. Since the fire suppressant 99 such as (1) forms a water film on the fuel (particularly a flammable liquid) to cover the fuel when returning from the foam state to the aqueous state, the flammable vapor of the fuel It is possible to suppress the evaporation and ignition of the fuel. Further, as long as the effects of the present invention are not impaired, ordinary additives such as pH adjusters (for example, amines such as monoethanolamine, triethanolamine and diethanolamine, and inorganic acids such as sodium tetraborate, sulfuric acid and nitrate) , Monoethanolamine is preferable for neutralizing acidity, and sulfuric acid is preferable for neutralizing alkalinity with organic acids such as acetic acid and citric acid) and rust preventives (aromatic compounds such as benzotriazole). It may be further included. The capacity CP (drug amount CP) of the enclosed fire suppressant 99 is about 2 liters in the case of the hand-held type, which is the same type as the conventional fire extinguisher, but the amount is smaller than this (for example). It may be 1 liter) or a large amount (for example, 6 liters). Further, the fire suppressant 99 may be colored or smelled. By coloring or smelling in this way, the sprayed (radiated) fire suppressant 99 adheres to the clothes of the arson terrorist criminal, etc., so that the arson terrorist criminal can be easily identified. Can be done.

(8) A chemical containing a flame retardant (flame retardant) has an effect of suppressing the combustion of general combustible materials such as wood, clothing, paper, and resin, like phosphates.

(Type of radiator 10)
The type of the radiator 10 having such a pressure-resistant container 11 is a hand-held type (similar to a conventional fire extinguisher, and the amount of chemicals CP to be sealed is 0.8 to 10 liters (preferably 1 to 6 liters). ) And a portable type (a portable aerosol type), for example, the amount of drug CP enclosed is preferably 1 liter or less (0.2 to 0.5 liter is preferable). ) Is the size of the pressure-resistant container 11). Further, the hand-held type or portable type radiator 10 can be sprayed with the fire suppressant 99 toward a specific place (for example, a building, a vehicle, a passage, an entrance / exit, etc. where an evacuation route is secured). There is also a fixed type that is fixed to a place, such as a wall or ceiling. The size of the radiator 10 is not limited to this, and if the radiator 10 has a size that can be carried like a fire extinguisher, it is a hand-held type, and if the radiator 10 is portable to a person, it is a portable type. And.

The dimensions of the hand-held type 2-liter radiator 10 of the present embodiment are, for example, 520 mm in height, 266 mm in width (horizontal length of the nozzle unit), and a pressure-resistant container as shown in FIGS. 1A to 1C. The diameter of 11 is 128 mm. Since this has substantially the same dimensions as a general 2-liter fire extinguisher, it is possible to use the parts of the conventional fire extinguisher as common parts for the radiator 10. By commonly using the parts used in the fire extinguisher for the radiator 10 in this way, the cost of the radiator 10 itself can be suppressed, and the radiator 10 can be made compatible with the recycling system of the fire extinguisher. It has become. The dimensions shown here are examples, and the radiator 10 may have dimensions different from the dimensions shown here, and the dimensions may be determined according to the amount of the drug to be sealed in the pressure-resistant container 11. Just do it.

In the hand-held type and the portable type, as described above, the fire suppressant 99 is sprayed (radiated) from the opening 20 of the nozzle 55 based on the operation of the handle 60, and is discharged to the combustible material 200. ..

Including those configured as.

The method of spraying (radiating) in the fixed type is the same as that of the hand-held type and the portable type, but the fire suppressant 99 enclosed by using a remote control or the like for remote control is sprayed (radiated) from the opening 20 of the nozzle 55. ) May be configured. For example, the fixed type radiator 10 is fixedly attached to a place where the fire suppressant 99 can be sprayed (radiated) in the range around the counter of the bank where the evacuation route can be secured. When fuel (flammable liquid) is intentionally sprinkled around the counter, the person operating the counter operates the spray switch on the remote controller to evacuate the fire suppressant 99 around the counter. It is configured so that it can be sprayed (radiated) within the range where the road can be secured. By spraying (radiating) the fire suppressant 99 of the fixed type radiator 10 over a wide area in a short time in this way, it is possible to secure an evacuation route.

Since such a fixed type radiator 10 does not require a large-scale construction work as compared with a conventional fixed type sprinkler or the like, it is possible to take very inexpensive disaster prevention measures, and it is a space-saving disaster prevention measure. ing. Further, since the fixed type radiator 10 is configured to spray (radiate) the fire suppressant 99 from the opening 20 of the nozzle 55 by remote control, the fire is not noticed and threatened by the criminal of the arson terrorism. It is possible to suppress. The fixed type radiator 10 may have a larger amount of chemicals than the hand-held type, and for example, a fire suppressant 99 in an amount of about 2 to 20 liters (preferably about 2 to 16 liters) is enclosed. The radiator 10 may be used.

(Structure of short-time radiation mechanism)
The radiator 10 of the present embodiment includes a short-time radiation mechanism as a mechanism capable of spraying (radiating) the fire suppressant 99 sealed in the pressure-resistant container 11 in a short time. The short-time radiation mechanism is composed of a pressurizing method (pressurizing means), an opening mechanism, and a distribution channel. When the amount of chemicals sealed in the pressure-resistant container 11 is 2 liters, a conventional fire extinguisher is configured to take 10 seconds or more to complete spraying (radiation). On the other hand, in the short-time radiation mechanism of the radiator 10 of the present embodiment, it takes less than 10 seconds, preferably within 5 seconds, particularly preferably within 2 seconds from the start to the completion of spraying (radiation). It is configured.

(Pressurization method (pressurization means))
The pressurization method includes a method in which the sealing plate 71 of the gas cartridge 70 bursts at once to release the pressure in an instant (for example, the above-mentioned pressurization type), and a state in which the pressure is constantly stored in the pressure-resistant container 11 is instantly stored. An example of a method of opening (for example, the above-mentioned accumulator method) and the like can be exemplified. The pressurization method may be any method as long as the pressure of the pressure-resistant container 11 can be increased and the fire suppressant 99 in the pressure-resistant container 11 can be released in an instant.

(Opening mechanism)
Examples of the opening mechanism of the radiator 10 include the above-mentioned pressurization type and the above-mentioned accumulator type.

(Distribution channel)
The distribution channel is composed of a first distribution channel 17, a second distribution channel 18, and a third distribution channel 19. The cross-sectional area S of the distribution path 16 (first discharge pipe 17 or second discharge pipe 18 or third discharge pipe 19) of the radiator 10 of the present embodiment is the cross-sectional area of the flow path of the conventional fire extinguisher. It is structured larger than the previous one. The cross-sectional area S1 of the first distribution path (first discharge pipe) 17, the cross-sectional area S2 of the second distribution path (second discharge pipe) 18, and the third distribution path (third discharge pipe) 19 The smallest cross-sectional area of the cross-sectional area S3 of the above is taken as the cross-sectional area S of the distribution channel 16 of the present embodiment. When the amount of drug CP enclosed in the present embodiment is 2 liters and the nozzle 55 is one radiator 10, for example, the cross section of the nozzle 55 is circular, and the distribution path 16 (for example, the third S3, which is the cross-sectional area S of the discharge pipe 19), has a size of 250 square millimeters.

Next, using FIG. 3, the structure of the distribution channel capable of radiating the drug in a short time will be described. FIG. 3 is a diagram showing a distribution route of the fire suppression chemical radiator 10 of the present embodiment and a distribution route of a conventional fire extinguisher. The cross-sectional area S of the distribution path 16 of the radiator 10 of the embodiment shown in FIG. 3, that is, the smallest cross-sectional area is the cross-sectional area S2 of the second distribution path 18 provided with the sealing plate 71. The cross-sectional area S3 of the third distribution route 19 and the cross-sectional area S1 of the first distribution route have the same area, which is larger than the cross-sectional area S2. Note that S2 has a slightly smaller area than S1 and S3, and S2 / S3 and S2 / S1 have values close to 1. When the sealing plate 71 is provided in the first distribution channel 17, the cross-sectional area S1 may be the smallest cross-sectional area.

The cross-sectional area of the distribution path of the conventional fire extinguisher, that is, the smallest cross-sectional area is the cross-sectional area S0 of the nozzle. The cross-sectional area S0 of the nozzle has an area smaller than the cross-sectional areas S1, S2, and S3 of the circulation path of the radiator 10, and S0 / S1, S0 / S2, and S0 / S3 are smaller than 1 (for example,). It is about 0.5, about 0.3, and even about 0.1), and it takes 10 seconds or more to finish radiating 2 liters of the drug. By configuring the distribution path 16 of the radiator 10 so as to have such a relationship, that is, the ratio of the cross-sectional area S0 of the nozzle 10 to the cross-sectional areas S1, S2, S3 of the distribution path of the radiator 10 (S1 / S0, By making S2 / S0, S3 / S0) larger than 1, it becomes possible to radiate the chemical in a shorter time than the conventional fire extinguisher. The length of the distribution path of the radiator 10 of the present embodiment (distance from the inlet to the outlet of the distribution path of the radiator 10 in FIG. 3) and the length of the distribution path of the conventional fire extinguisher (fire extinguishing in FIG. 3). It may be the same length as the distance from the entrance to the exit of the distribution channel of the vessel. Further, the amount of chemicals CP enclosed in the radiator 10 of the present embodiment and the conventional fire extinguisher is 2 liters, but other chemical amounts may be used.

Further, as shown in FIGS. 1C, 7A, and 7B, for example, a radiator 10 having a chemical amount CP of 2 liters and having a plurality of nozzles 55, as in the case of two nozzles 55. In the case of 10, the cross section of the nozzle 55 may be circular. In this case, S3, which is the cross-sectional area of one distribution path 16 (third discharge pipe 19) in the case of the radiator 10 having a plurality of nozzles 55, has an area of 125 square meters, which is smaller than that in the case of one nozzle 55. It is composed of millimeters in size. Amount of medicine to be enclosed In a radiator 10 having a CP of 2 liters, the time required to complete spraying (radiation) of 2 liters of medicine is the same when there is one nozzle and when there are multiple nozzles. Is the sum of the cross-sectional area of one flow path 16 (for example, 250 square millimeters) when there is one nozzle and the cross-sectional area of a plurality of flow paths 16 having a plurality of nozzles (for example, 125 square millimeters × 2 = 250). Square millimeters) and are configured to be the same. With this configuration, even when a plurality of nozzles 55 are provided, the same performance as when one nozzle 55 is provided can be obtained. When there are a plurality of nozzles 55, the cross-sectional area S3 of the third discharge pipe 19, which is a distribution path connected to the nozzles 55, needs to be the smallest.

The size of the cross-sectional area S illustrated in the pressurizing type of this embodiment is in the order of S1> S2> S3. The cross-sectional area S1 of the first discharge pipe 17, which is the distribution path on the side where the fire suppressant 99 starts to flow, is the largest, and the cross-sectional area S3 of the third discharge pipe 19 closest to the nozzle 55 (about 80 of S1). % Cross-sectional area) is configured to be the smallest. Further, the size of the cross-sectional area S illustrated in the accumulator formula of the present embodiment is S1 = S2 = S3, and the cross-sectional areas of all distribution channels are the same. In the case of a general accumulator type, a valve is provided between the first discharge pipe 17 and the second discharge pipe 18, and the valve is opened based on the operation of the handle 60. Therefore, S2 Is smaller than S1, but in the accumulator type of the present embodiment, as shown in FIG. 2, a sealing plate 71 is provided between the first discharge pipe 17 and the second discharge pipe 18. As a result, since S1 and S2 can have the same cross-sectional area, the fire suppressant 99 can flow down the flow path on the downstream side without reducing (changing) the flow velocity of the fire suppressant 99. It has become. The pressurized cross-sectional area S shown in FIGS. 1A to 1C may also be configured such that S1 = S2 = S3, and by configuring so, the flow velocity of the fire suppressant 99 is reduced. The effect is that the fire suppressant 99 can flow down the distribution channel on the downstream side without (changing). The cross-sectional shape of the distribution channel 16 may be an elliptical shape, a rectangular shape, or the like in addition to the circular shape.

Further, the ratio of the capacity CP (drug amount CP) of the fire suppressant stored in the pressure-resistant container 11 of the radiator 10 of the present embodiment to the cross-sectional area S of the distribution path 16 has the following relational expression. It is configured.
(Relational formula) (Chemical amount CP stored in pressure-resistant container 11): (Cross-sectional area S of distribution channel 16) = (2 liters): (50 square millimeters or more, preferably 80 square millimeters or more, more preferably 100 square millimeters) Millimeters or more, upper limit is, for example, 600 square millimeters or less, preferably 500 square millimeters or less, more preferably 400 square millimeters or less)

In the case of 1 liter, the amount of drug CP: cross-sectional area S = 1 liter: (25 square millimeters or more, preferably 40 square millimeters or more, more preferably 50 square millimeters or more, the upper limit is, for example, 300 square millimeters or less, preferably 250 square millimeters or less, more preferably 200 square millimeters or less). In this way, by using the cross-sectional area S having a capacity CP of 25 square millimeters or more with respect to 1 liter, the fire suppressant 99 in the pressure-resistant container 11 is sealed in the pressure-resistant container 11 in less than 10 seconds regardless of the capacity CP. It is configured so that the fire suppressant 99 that has been used can be sprayed (radiated). Although an example in which the ratio of the capacity CP and the cross-sectional area S is 1 liter: 25 square millimeters or more is shown, a preferable example is a capacity CP: cross-sectional area S = 1 liter: 125 square millimeters or more. It is preferable to use the low resistance distribution path 16 so that the fire suppressant 99 in the pressure resistant container 11 can be released in an instant.

The cross-sectional area S of the distribution path 16 that enables the drug amount CP enclosed in the pressure-resistant container 11 to be sprayed (radiated) within 10 to 2 seconds is as follows.
(Portable type 1) In the case of a drug amount CP of 0.2 liter, a cross-sectional area S of 5 square millimeters or more is required. The cross-sectional area S is preferably 25 square millimeters or more, more preferably 50 square millimeters or more, and the upper limit value may be 300 square millimeters or less.
(Portable type 2) In the case of a drug amount CP of 0.5 liter, a cross-sectional area S of 12.5 square millimeter or more is required. The cross-sectional area S is preferably 25 square millimeters or more, more preferably 62.5 square millimeters or more, and the upper limit value may be 300 square millimeters or less.
(Hand-held type 1) In the case of 1 liter of drug amount CP, a cross-sectional area S of 25 square millimeters or more is required. The cross-sectional area S is preferably 125 square millimeters or more, and the upper limit value may be 300 square millimeters or less.
(Hand-held type 2) In the case of a drug amount CP of 2 liters, a cross-sectional area S of 50 square millimeters or more is required. The cross-sectional area S is preferably 250 square millimeters or more, and the upper limit value may be 600 square millimeters or less.
(Hand-held type 3) In the case of a drug amount CP of 3 liters, a cross-sectional area S of 75 square millimeters or more is required. The cross-sectional area S is preferably 375 square millimeters or more, and the upper limit may be 900 square millimeters or less.
(Hand-held type 4) In the case of a drug amount CP of 4 liters, a cross-sectional area S of 100 square millimeters or more is required. The cross-sectional area S is preferably 500 square millimeters or more, and the upper limit value may be 1200 square millimeters or less.
(Hand-held type 5) In the case of a drug amount CP of 5 liters, a cross-sectional area S of 125 square millimeters or more is required. The cross-sectional area S is preferably 625 mm2 or more, and the upper limit may be 1500 mm2 or less.
(Hand-held type 6) In the case of a drug amount CP of 6 liters, a cross-sectional area S of 150 square millimeters or more is required. The cross-sectional area S is preferably 750 mm2 or more, and the upper limit may be 1800 mm2 or less.
(Fixed type 1) In the case of a drug amount CP of 16 liters, a cross-sectional area S of 400 square millimeters or more is required. The cross-sectional area S is preferably 2000 square millimeters or more, and the upper limit value may be 4800 square millimeters or less.

For example, when the drug amount CP enclosed in the pressure-resistant container 11 is sprayed (radiated) within 2 seconds, the lower limit of the cross-sectional area S [square millimeter] = 125 × the drug amount CP [liter]. ing. Further, when the drug amount CP enclosed in the pressure-resistant container 11 is sprayed (radiated) within 5 seconds, the lower limit of the cross-sectional area S [square millimeter] = 50 × the drug amount CP [liter]. ing. Further, when the chemical amount CP enclosed in the pressure-resistant container 11 is sprayed (radiated) in 10 seconds or more (in the case of a conventional fire extinguisher), the upper limit of the cross-sectional area S [square millimeter] = 25 × the chemical amount CP [ It is configured to be [liter].

When the length of the distribution channel 16 is the same and the cross-sectional area S of the distribution channel 16 is constant, the cross-sectional area S and the drug amount CP are proportional. Here, assuming that the flow rate is Q [liters / minute], the diameter of the distribution path is ΦD [millimeters], the pressure is P [megapaspal], and the flow coefficient is Cp, the smallest cross-sectional area S (the length of the distribution path 16 is almost the same). The flow rate Q for (which does not change) can be expressed by the following equation.
Q = Cp × ΦD ^ 2 × (√P) × (√0.098)
However, it goes without saying that the flow coefficient Cp changes not only with the diameter φD and length of the distribution channel, but also with its cross-sectional shape, roughness, and material, and also with the physical characteristics of the drug and the nozzle structure.

As shown in FIG. 6B, the upper deflector 201a has a shape that is opened at a predetermined angle in the upward direction. On the other hand, as shown in FIG. 6A, the lower deflector 201b has a shape that opens at a predetermined angle in the left-right direction. Further, the upper deflector 201a and the lower deflector 201b are formed with a plurality of rectangular slits, specifically, rectangular slits 220a to 220d, as shown in FIG. 6C. A wire mesh 202 is attached to the front side of the deflector 201, and the fire suppressant 99 that has flowed down the third discharge pipe 19 and the opening 20 entrains air when passing through the wire mesh 202, resulting in a bubble state. It is configured to be released to the outside.

The fire suppressant 99 that has flowed down the third discharge pipe 19 is discharged from the opening 20 toward the upper deflector 201a and the lower deflector 201b. A part of the fire suppressant 99 released from the opening 20 is sprayed (radiated) by the lower deflector 201b on the rear side of the lower deflector 201b and along the rear surface of the lower deflector 201b as shown by the alternate long and short dash line in FIG. 6A.

Next, a radiator 10 having a foam head nozzle arranged with a double angle as a nozzle structure will be described. FIG. 7 is a diagram showing a nozzle structure of a foam head 100 arranged with a double angle. FIG. 7A is a top view showing a nozzle structure of the foam head 100 arranged with a double angle. FIG. 7B is a side view of the nozzle structure of the foam head 100 arranged at a double angle. When the fire suppressant 99 discharged from the nozzle 55 is foamed and sprayed (radiated) to the outside, a plurality of foam heads 100 can be provided at the tip of the nozzle 55. The structure in which the nozzle 55 and the plurality of foam heads 100 are integrated is treated as the foam head nozzle 55. As a nozzle structure capable of spraying (radiating) over a wide range in the left-right direction, as shown in FIG. 7A, the nozzle structure of the foam heads 100 having a double angled arrangement in which two foam heads 100 are attached at a predetermined angle (α degree). Is preferable. As the foam head 100, the foam head 100 described above is used.

(Number of nozzles)
As shown in FIGS. 1A to 1C and 7A, the number of nozzles 55 provided in the radiator 10 is plurality on the left and right (for example, 2) when the nozzles 55 (foam head nozzles) are facing the combustible material 200. It is preferable to provide (pieces). As shown in FIGS. 2 and 3, one nozzle 55 may be provided, or a plurality of nozzles 55 (foam head nozzles) may be provided vertically (for example, as shown in FIG. 7B). (2) may be provided, or a plurality of nozzles 55 may be mounted at different positions in the circumferential direction as shown in FIG. 7A. Further, although it is preferable to provide a plurality of spray (radiation) holes (plural openings 20) in one nozzle 55, one spray (radiation) holes (one opening 20) may be provided. When a plurality (for example, two) nozzles 55 are provided vertically as shown in FIG. 7B, the upper nozzle 55 sprays the fire suppressant 99 at a position (long distance) far from the nozzle 55 (for example, two nozzles 55). On the other hand, the lower nozzle 55 may be configured to spray (radiate) the fire suppressant 99 at a position (short distance) close to the nozzle 55. Further, the upper nozzle 55 may be used for a short distance and the lower nozzle 55 may be used for a long distance. With this configuration, it is possible to generate a layer of the fire suppressant 99 having a certain level or more (1 mm or more) even at a short distance and a long distance position. Furthermore, by making the cross-sectional area S of the distribution path 16 connected to the upper nozzle 55 and the lower nozzle 55 different, the fire suppressant is used for short distances (when the cross-sectional area is large) and long distances (when the cross-sectional area is small). 99 may be configured to be sprayed (radiated).

(Nozzle arrangement structure)
When a plurality of nozzles 55 (foam head nozzles) are used, it is preferable to arrange them at an angle of α degree as shown in FIG. 7A. An example of 15 degrees as α here is shown, but it is preferable that α is 5 to 45 degrees. Further, as shown in FIG. 7B, a plurality of nozzles 55 may be provided vertically in a side view instead of a left-right direction when facing the combustible material 200, or a plurality of nozzles 55 may be provided in the left-right direction (for example, two). It may be configured to be provided and a plurality (for example, two) are provided in the vertical direction, and a plurality (for example, four) nozzles 55 may be arranged. It is preferable that the fire suppressant 99 has a nozzle structure, a number of nozzles, and a nozzle arrangement structure so that the same amount can be sprayed (radiated) in a predetermined range (for example, about 4 square meters / 1 liter). The nozzle 55 may be tilted upward several degrees and fixed.

(Structure of safety radiation mechanism)
The radiator 10 of the present embodiment is a mechanism that reduces the emission sound when spraying (radiating) the fire suppressing agent 99 and has a low reaction to the operator when spraying (radiating) the fire suppressing agent 99. It may be provided with a safety radiation mechanism. The safe radiation mechanism of the radiator 10 of the present embodiment includes a silent mechanism and a low recoil mechanism.

(Silent mechanism)
For example, as described in the above-mentioned number of nozzles, one nozzle 55 is configured to provide a plurality of spray (radiation) holes. By providing a plurality of spraying (radiating) holes in this way, the emitted sound when the fire suppressant 99 is sprayed (radiated) is dispersed, so that the emitted sound can be reduced. In addition, by reducing the emission sound in this way, it is possible to prevent the criminal from being threatened in the event of an arson terrorist attack or the like.

(Low recoil mechanism)
Next, the low recoil mechanism will be described with reference to FIGS. 8A to 8C. 8A to 8C are diagrams showing a circumferential radiation mechanism as a low recoil mechanism. The fire suppressant 99 sprayed (radiated) from the nozzle 55 as shown in FIG. 8A is sprayed (radiated) from the nozzle 55 in the circumferential direction (fan shape with a central angle of β1 degree) in the top view and as shown in FIG. 8B. By spraying (radiating) the fire suppressant 99 in the circumferential direction (fan shape with a central angle of γ degrees) even when viewed from the side, the vector of the reaction to the spraying (radiation) is indicated by the one-point chain line arrow in the figure. Therefore, it is configured so that the reaction to the operator is small (circumferential radiation mechanism). The circumferential direction (horizontal direction in the normal spraying state) in the top view shown in FIG. 8A is configured to spray (radiate) from the nozzle 55 at an angle of β1 degree, and β1 degree is 30 degrees. It is in the range of ~ 120 degrees.

Further, in the circumferential direction (vertical direction in the normal spraying state) in the side view shown in FIG. 8B, the nozzle 55 is configured to spray (radiate) at an angle of γ degree, and the γ degree is 15 degrees. It is in the range of ~ 90 degrees.

Further, as shown in FIG. 8C, the fire suppressant 99 sprayed (radiated) from the two nozzles 55 (foam head nozzles) is in the circumferential direction (fan shape with a central angle of β2 degrees) in the top view and in FIG. 8B. As shown in the above, the fire suppressant 99 sprayed (radiated) from the nozzle 55 is sprayed (radiated) in the circumferential direction (fan shape with a central angle of γ degrees) even when viewed from the side, so that the reaction to the spraying (radiation) is generated. Since the vector is dispersed, it is configured so that the reaction to the operator is small (circumferential radiation mechanism). The circumferential direction in the top view shown in FIG. 8C is configured to be sprayed (radiated) from the nozzle 55 at an angle of β2 degrees, and β2 degrees is in the range of 90 degrees to 150 degrees. ..

Further, as shown in FIGS. 7A and 8C, a plurality of nozzles 55 are provided at angles of α degree and β2 degree, and the fire suppressant 99 is sprayed (radiated) in different directions in FIGS. 8A and 8B. Since the reaction vector for spraying (radiation) is dispersed as shown, the reaction to the operator is small (multiple nozzle angled radiation mechanism). The nozzle 55 of one of the plurality of nozzles angled radiation mechanisms may use a circumferential radiation mechanism. With such a configuration, it is possible to obtain a low recoil mechanism that has a lower recoil than the nozzle multiple angled radiation mechanism. Further, the low recoil mechanism is preferably composed of a circumferential radiation mechanism and a plurality of nozzle angled radiation mechanisms, but may be composed of only one of them.

Next, in order to suppress a fire, a preferable relationship between the sprinkled fuel (flammable liquid) and the amount of the chemical required for the control will be described.
(1) Gasoline: Water film formation foam = 1: 0.3 or more Water film formation foam of 0.3 liter or more is required for 1 liter of gasoline.
(2) Gasoline: Synthetic surfactant foam = 1: 1 or more 1 liter or more of synthetic surfactant foam is required for 1 liter of gasoline. The amount of the synthetic surfactant foam is required to be larger than that of the water-formed foam (three times or more the amount of the water-formed foam).
(3) Kerosene: Water film formation = 1: 0.1 or more Water film formation of 0.1 liter or more is required for 1 liter of kerosene. Since kerosene has a higher flash point than gasoline, the amount of chemicals can be reduced.

Next, the protection range area S4 will be described. 9A to 9C are diagrams showing the protection range area S4. As shown in FIG. 9A, the protection range (protection range area S4) that can suppress a fire by using the type A nozzle 55 is a substantially square range. Further, when a type B nozzle 55 different from the type A nozzle is used, the protection range area S4 capable of suppressing a fire is a substantially rectangular range as shown in FIG. 9B. Further, when a type C nozzle 55 different from the type A and type B nozzles is used, the protection range area S4 capable of suppressing a fire rotates a rectangle using the type B nozzle 55 by 90 degrees as shown in FIG. 9C. It is in the range of a substantially rectangular shape. Here, the protection range area S4 indicates an area in which an amount (thickness) of a fire suppressant 99 effective for extinguishing a fire or suppressing ignition is sprayed. The thickness of the sprayed fire suppressant 99, and the effective thickness of the fire suppressant 99, is 1 mm or more in terms of the volume of foaming (for example, the foaming ratio is 4 times). The area of the protection range S4 is smaller than the area actually sprayed (radiated), and the area in which the thickness of the fire suppressant 99 is 1 mm or more in the actually sprayed area. It is an area. Even if the types of the nozzles 55 are different, the protection range area S4 capable of suppressing a fire may be configured to have the same area. The shape of the protection range area is not limited to the above-mentioned substantially square or substantially rectangular shape, and can be appropriately selected from a substantially trapezoidal shape, a substantially circular shape, a substantially elliptical shape, and the like.

Alternatively, type A, type B, and type C nozzles may be attached to the radiator 10 of 1 so that types A to C can be selected and used (nozzle selection mechanism). For example, the nozzles 55 of types A to C can be attached in the circumferential direction of the radiator 10 and rotated to select the nozzle 55 of the type to be used. By using the Nozzle of Type C and using the Nozzle of Type C for narrow passages, etc., the protection range to which the fire suppressant 99 is sprayed (radiated) can be changed depending on the situation. There is. By selecting and using the type of the nozzle 55 in this way, it is possible to spray (radiate) the fire suppressant 99 over the optimum protection range. The nozzle selection mechanism can be applied to any of the portable type, the hand-held type, and the fixed type radiator 10.

Next, the relationship between the drug amount CP and the protection range area S4 capable of suppressing a fire will be described. Here, an example is shown in which the thickness of the foam that can be suppressed is 1 mm and the foaming ratio is 4 times.
(Portable type 1) In the case of a 0.2 liter drug amount CP, it is possible to suppress a fire with a protection range area S4 of 0.8 square meters.
(Portable type 2) In the case of a drug amount CP of 0.5 liter, it is possible to suppress a fire with a protection range area S4 of 2 square meters.
(Hand-held type 1) In the case of 1 liter of chemical amount CP, it is possible to suppress a fire with a protection range area S4 of 4 square meters.
(Hand-held type 2) In the case of 2 liters of chemical amount CP, it is possible to suppress a fire with a protection range area S4 of 8 square meters.
(Hand-held type 3) In the case of a chemical amount CP of 3 liters, it is possible to suppress a fire with a protection range area S4 of 12 square meters.
(Hand-held type 4) In the case of a drug amount CP of 4 liters, it is possible to suppress a fire with a protection range area S4 of 16 square meters.
(Hand-held type 5) In the case of a chemical amount CP of 5 liters, it is possible to suppress a fire with a protection range area S4 of 20 square meters.
(Hand-held type 6) In the case of a 6-liter drug amount CP, it is possible to suppress a fire with a protection range area S4 of 24 square meters.
(Fixed type 1) In the case of a drug amount CP of 16 liters, it is possible to suppress a fire with a protection range area S4 of 64 square meters.
That is, S4 [square meter] = 4 × drug amount CP [liter].

As described above, the conventional fire extinguisher filled with 2 liters of the drug is configured to be able to spray (radiate) substantially the entire amount of the drug over a period of 10 seconds or more. Therefore, since there is sufficient time from the sprinkling of the fuel (flammable liquid) to the ignition, the fuel can be easily ignited and the chemical is sprayed (evaporated) on the sprinkled fuel. There is a risk that the fuel will evaporate and explode and burn. In addition, conventional fire extinguishers cannot spray (radiate) chemicals over a wide area without shaking the nozzle to spray (radiate) the chemicals, so the problem is to spray (radiate) the chemicals over a wide area. It has become.

In addition, conventional arson fire prevention devices and arson suppression systems use sensors to determine arson behavior and take preventive measures by using light, sound, water spray, water spray, etc., but highly volatile fuels such as gasoline (flammable) There is a problem that it does not suppress arson when sprinkled with (sexual liquid). Further, the automatic device has a problem that not only the cost of the device itself is very high, but also the installation work and the like are costly and time-consuming.

The following concepts can be extracted based on the configuration shown in the first embodiment described above. However, the concepts described below are merely examples, and not only the combination and separation (superimposition) of these concepts, but also the concepts based on the further configuration shown in the first embodiment are added to these concepts. You may.

Artificial fires such as arson terrorism caused by a person intentionally sprinkling fuel (flammable liquid) and igniting it are difficult to prevent, especially after the fuel has been sprinkled. If it is ignited after the lapse of time, not only will it explode and burn, but it will be extremely difficult to extinguish the fire after ignition. Therefore, by using a portable suppressive drug radiator to radiate the drug mainly over a wide area of the floor surface in a short time, the evaporation of the fuel after the person intentionally sprinkles the fuel is suppressed. In addition, the chemical radiation method and the chemical radiator for suppression that can suppress the ignition and explosive combustion of the fuel and secure the evacuation route are shown below.

(Drug radiation method)
A chemical having a flame-retardant effect (for example, a fire suppressant 99) stored in a portable storage container (for example, a pressure-resistant container 11) is charged with respect to 1 liter of the chemical stored in the storage container. After flowing into a distribution channel (for example, distribution channel 16) having a cross-sectional area of 25 square millimeters or more, the drug is discharged from the opening (for example, opening 20) while expanding the flow of the drug with the flow of the drug. It is possible to provide a drug radiating method for radiating a drug to an object (for example, a combustible material 200). Further, in this drug radiating method, the drug stored in the storage container is radiated within, for example, 2 seconds.
