BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simulated fire generating device applied to fire training.

[0002]

2. Description of the Related Art A conventional simulated fire generating device is shown in FIG.
A simulated fixture 1 such as a kitchen is installed on a grid-shaped floor 2, and a fuel pipe 3 having a burner 4 is installed below the floor 2.
A receiving box 7 for collecting the extinguishing liquid is arranged below the burner 4 for generating flames, and sensors 8 for detecting the amount of the extinguishing liquid are provided at one end of the receiving box 7.

Reference numeral 5 is a fuel tank for storing the fuel supplied to the burner 4 through the fuel pipe 3, reference numeral 6 is a control valve for controlling the supplied fuel amount, and reference numeral 9 is a control valve based on the signal received from the sensors 8. 6 is a control panel for performing opening / closing control of No. 6.

When entering, the amount is detected by the sensors 8 and, if necessary, the control valve 6 is closed to suppress the flame.

[0005]

The conventional simulated fire generating device described in the preceding paragraph has the following problems.

(1) The combustion burner 4 and the fuel pipe 3 are arranged above the receiving box 7 and the sensor 8 for collecting and detecting the fire extinguishing liquid. In this structure, the fire extinguishing liquid is always used during the extinguishing work. 4 and the fuel pipe 3. During combustion, the temperature of the combustion section becomes high, but if a large amount of cold extinguishing liquid is suddenly applied to it, it will be cooled.
If you repeat this process, the burner and other combustion parts will heat up.
Repeated cooling causes thermal fatigue, and durability and safety are significantly impaired.

(2) When attempting to simulate an actual fire, it is necessary to create not a point combustion but a surface combustion as necessary. However, the conventional burner configuration is a point combustion, and therefore an actual fire. The difference from combustion is large.

(3) The simulated fire generating device such as this device is highly required to be installed indoors. Therefore, the fuel must be cleanly burned without soot after burning. At this time, make a clean combustion, that is, as it approaches complete combustion,
The color of the flame changes from red to blue. For this reason, there is a contradiction that the difference from the color at the time of the actual fire becomes large.

It is an object of the present invention to improve the durability of a flame generator and to provide a simulated fire generating device which can better simulate an actual fire.

[0010]

In order to solve the above-mentioned problems, a simulated fire generating device according to the present invention is provided with a floor with a lattice on which a simulated fixed object such as furniture can be installed, and below the same floor. A flame generating furnace with an igniter that generates a flame, a receiving box installed next to the flame generating furnace to collect the extinguishing liquid or extinguishant, and the amount of the extinguishing liquid or extinguishing agent attached to the receiving box. It is equipped with sensors.

Further, the simulated fire generator according to the present invention is
The confluence hood provided to cover the flame generation furnace and the receiving box, a control panel for receiving signals from the sensors, and an amount of fuel supplied to the flame generation furnace in response to a command from the control panel. And a control valve for controlling.

In the simulated fire-generating apparatus of this structure according to the present invention, the flame-generating furnace and the receiving box for collecting the extinguishing liquid are arranged in a horizontal direction, not in a vertical relationship, and are installed above the flame-generating furnace and the receiving box. Since the confluent hood covers the entire upper surface of the flame-generating furnace, the fire-extinguishing liquid does not reach the fire-generating furnace. Therefore, the high temperature flame generating furnace is not rapidly cooled by the extinguishing liquid, and the durability is improved. The fire-extinguishing liquid is dropped and collected in a receiving box installed below the floor with a grid where simulated fixtures are installed.

The flame generating furnace of the above-described simulated fire generating apparatus according to the present invention is preferably constructed so that the inside is divided into two chambers, an upper chamber and a lower chamber, by a partition having a fine porous structure, and the fuel enters the lower chamber. Sintered metal can be used for the partition walls having a fine porosity. In the simulated fire generating device configured as described above, the fuel is ejected from the partition wall having a fine porous structure provided in the flame generating furnace, so that the area of the combustion portion is increased and combustion can be generated on the surface.

Further, in the simulated fire generating apparatus according to the present invention, the inside of the flame generating furnace is divided into two chambers, an upper chamber and a lower chamber, by partition walls having a fine porous structure so that water can enter the upper chamber and fuel can enter the lower chamber. adopt.

The fuel contained in the lower chamber of the two chambers divided by the partition wall having the fine porosity is ejected from the partition wall having the fine porosity to increase the area of the combustion portion and burn on the surface. In addition to this, the water contained in the upper chamber has two functions: a diffusion function for evenly supplying fuel gas to the combustion area part and a safety function for separating the combustion part and the tank. That is, first, as the diffusion function, each porous of the partition walls functions as a nozzle to increase the combustion area. On the other hand, the temperature of the partition wall becomes very high, and the pore size of the porous layer changes due to melting of the partition wall, etc., which causes difficulty in safety and stability. However, the water contained in the upper chamber is safe and stable. To maintain.

Further, in the simulated fire-generating apparatus according to the present invention, the inside of the fire-generating furnace is divided into three upper, middle and lower chambers by providing two partition walls having fine pores, water in the upper chamber, fuel in the middle chamber, and lower chamber. A structure that allows compressed air to enter the room will also be adopted.

By using the simulated fire-generating apparatus having the flame-generating furnace configured as described above, air is supplied from the lower chamber through the fine porous partition wall to the middle chamber to which the fuel is supplied, so that the fuel and the air are well mixed. Good mixing with good flame and soot-free mixing. In addition, as described above, the water contained in the upper chamber functions to evenly flow the fuel gas out of the pores of the partition wall to create a large combustion area, and the temperature of the partition wall becomes extremely high. Prevents changes in hole size from causing difficulties in safety and stability, and maintains its safety and stability.

Furthermore, in the simulated fire-generating device according to the present invention, the water in the upper chamber of the flame generating furnace divided by the fine porous partition wall as described above is mixed with a sodium compound such as sodium chloride (NaCl). adopt.

By adopting the flame generating furnace configured as described above and passing the fuel through water containing sodium compounds such as sodium chloride (NaCl), when Na dissolves in the fuel and burns, Na reacts and the flame becomes red. It can be close to the color of the actual fire.

BEST MODE FOR CARRYING OUT THE INVENTION A simulated fire generating device according to the present invention will be specifically described below based on the embodiments shown in FIGS. In the following embodiments, the same components as those of the conventional device shown in FIG. 4 are designated by the same reference numerals for simplification of description.

(First Embodiment) First, an apparatus according to the first embodiment shown in FIG. 1 will be described. In FIG. 1, a simulated fixture 1 such as a kitchen is installed on a grid-like floor 2, and a flame generating furnace 12 is installed below the simulated fixture 1 with a space. A partition 14 having a fine porous structure made of a sintered metal is installed in the flame generating furnace 12. Here, the partition wall 14
May be installed but not installed.

An igniter 10 is installed in the upper portion of the flame generating furnace 12. Fuel is supplied to the flame generating furnace 12 from the fuel tank 5 through the fuel pipe 3 and through the control valve 6 and the flashback prevention valve 17. A receiving box 7 for receiving the extinguishing liquid during the extinguishing work is installed at a lateral position of the flame generating furnace 12, and the receiving box 7 is equipped with various sensors 8 for detecting the amounts of the extinguishing liquid and the extinguishing agent. It is connected to a measurement panel 9 that receives measurement signals.

A merging hood 11 is installed on the flame generating furnace 12 and the receiving box 7. The merging hood 11 has an inclined heat-resistant material 16 covering the upper side of the flame generating furnace 12, and the fire extinguishing liquid or the extinguishing agent applied to the simulated fixture 1 on the floor 2 above the flame generating furnace 12 is the flame generating furnace 12. It acts so that it will not fall and is guided downward.

The merging hood 11 has an opening above the receiving box 7, and guides the flame generated in the flame generating furnace 12 toward the simulated fixed object 1 on the floor 2 and drops from above as described later. The extinguishing liquid and the extinguishing agent coming in are received in the receiving box 7.

Next, the operation of the apparatus shown in FIG. 1 will be described. When the fuel supply from the fuel tank 5 starts, the gas starts to be emitted from the flame generating furnace 12. The gas is ignited by the igniter 10 to create a flame. The size of the flame is adjusted by the opening degree of the control valve 6 that controls the fuel amount according to a command from the measurement panel 9.

Since the partition wall 14 having a fine porosity is installed in the flame generating furnace 12, the fuel is the partition wall 1.
Eject from No. 4 and burn on the surface. In this way, the flame generated in the flame generating furnace 12 comes out from the upper opening of the merging hood 11 and burns the simulated fixed object 1.

During the fire extinguishing work, the extinguishing liquid or the extinguishing agent falls from the upper opening of the merging hood 11 into the receiving box 7 directly below, and falls on the flame generating furnace 12 on the side. Due to its presence, it does not fall directly into the flame producing furnace 12. In this way, the cold fire extinguishing liquid is directly used in the flame generation
Since it does not reach 2, the life of the flame generating furnace 12 is extended without a thermal strength reduction. Further, the amount of the fire extinguishing liquid or the fire extinguishing agent dropped into the receiving box 7 can be detected by the sensors 8 mounted on the receiving box 7, and the fire extinguishing can be judged.

In the apparatus according to the second embodiment shown in FIG. 2, the interior of the flame generating furnace 12 is divided into two upper and lower chambers by a partition wall 14 having a fine porous structure, water is stored in the upper chamber 15 and water is stored in the lower chamber 13. Fuel is supplied from the fuel tank 5 via the control valve 6 and the flashback prevention valve 17. By allowing the fuel to pass through the partition walls 14 having a large number of fine pores, the combustion area is increased and a large flame can be created.

On the other hand, in the water stored in the upper chamber 15, the temperature of the partition wall 14 becomes very high, the partition hole 14 is melted, etc., and the pore size of the porous layer is changed. Prevent coming. The situation at the time of fire extinguishing work is the first
The description is omitted because it is the same as the case of the apparatus of the form.

(Third Embodiment) Next, an apparatus according to the third embodiment shown in FIG. 3 will be described. In the simulated fire generating device shown in FIG. 3, the inside of the flame generating furnace 12 is divided into upper, middle and lower three chambers by two partition walls 14a, 14b having a fine porous structure, and water is stored in the upper chamber 15, From the fuel tank 5 to the chamber 13, the control valve 6 and the flashback prevention valve 17 are provided.
The fuel is supplied via the
Compressed air is supplied from the compressor 18 via the.

In this flame generating furnace, since air is uniformly supplied to the inner chamber 13 through the lower partition wall 14b having a fine porosity, a large amount of fuel and air can be mixed by this, and a larger flame is generated. It is possible to obtain good combustion without generation of soot. In addition, the water stored in the upper chamber 15 of the upper partition wall 14a has a very high temperature, and the pore size of the porous layer changes due to the melting of the upper partition wall 14a. Prevent problems from occurring. The situation at the time of fire extinguishing work is the same as in the case of the previous embodiment, and therefore the description is omitted.

In the second and third embodiments described above, if a sodium compound such as salt is put in the water stored in the upper chamber 15 of the flame generating furnace 12, the sodium compound will be generated when the fuel passes through the water. Since it adheres to the fuel and produces a red flame upon combustion, it is preferable because it can simulate an actual fire well.

[0033]

As described above, in the simulated fire generating device of the present invention, the receiving box for collecting the extinguishing liquid or the extinguishant is installed beside the flame generating furnace, and the confluent hood is provided so as to cover the flame generating furnace. Since the fire extinguishing liquid is not directly applied to the flame generator, the durability of the flame generating furnace is greatly improved.

Further, in the present invention, the inside of the flame generating furnace is divided into two chambers, an upper chamber and a lower chamber, by partition walls having fine pores.
In a simulated fire generator configured so that water can enter the upper chamber and fuel can enter the lower chamber, the fuel can be ejected from the partition walls with fine pores to increase the combustion area and increase the flame, and also generate a flame on the surface. Can be made.

Further, the temperature of the partition wall of water contained in the upper chamber becomes very high, and the pore size of the porous layer is changed due to melting of the partition wall or the like, thereby preventing problems in safety and stability. , Maintain its safety and stability.

Further, in the present invention, the interior of the flame generating furnace is divided into three upper, middle and lower chambers by providing two stages of partition walls having fine pores, and water is introduced into the upper chamber, fuel is introduced into the intermediate chamber and compressed air is introduced into the lower chamber.
