Description

FIELD OF THE INVENTION [0001] The present invention relates to a fire propagation delay device and a fire propagation delay device,

The technology relates to a fire spread delay device that is interlocked with an evaporative cooling device.

Evaporative cooling is one of the cooling methods that utilize the fact that the surrounding temperature is lowered by absorbing the heat around the evaporation heat in the process of water evaporation. Conventionally, a sprinkler for spraying water in all directions or a powder fire extinguisher automatically radiating in case of fire is used to prevent fire spread.

Evaporative cooling systems are used in multi - use facilities and employ fine mist spray mist nozzles for fine mist spraying to prevent condensation and water fall. The spraying capacity per minute of the fine mist spray mist nozzle is 30 to 40 CC / min. The straight line reach distance of the mist sprayed through the mist nozzle is about 2 meters, and the particle size of the water sprayed through the nozzle is also 10 to 20 μm. Therefore, it may be insufficient to suppress the propagation of the fire by individually spraying fine mist spray mist nozzles.

A sprinkler suppresses fire by suppressing fire or spraying water with a maximum of 120 L / min per nozzle to suppress fire propagation, and suppresses fire propagation. However, since a large amount of water is sprayed in all directions, unnecessary property damage may occur. Furthermore, powder fire extinguishers have a narrow spray range and are uneconomical for use in large areas such as traditional markets, arcades or shopping malls.

The present embodiment is intended to overcome and overcome the problems of the prior art described above. That is, by providing a fire diffusion delay device interlocked with an evaporative cooling device, it is possible to suppress the fire early in the event of a fire in the same evaporative cooling device, to suppress the spread of fire, and to minimize unnecessary property loss due to irregular application of water And to provide a fire spread delay device interlocked with the evaporative cooling device.

The fire diffusion retarding apparatus according to the present embodiment includes: an evaporative cooling unit that performs cooling by spraying a fluid mist; a fluid pipe; a plurality of fire diffusion retarded spray nozzle units disposed along the fluid pipe to spray fluid mist; A plurality of solenoid valves connected to the fluid piping to provide or block fluid to a plurality of fire retarding spray nozzle units and a plurality of fire sensors disposed at a distance along the fluid pipe to monitor fire indications, A pump for providing fluid through the fluid piping and a plurality of solenoid valves for providing fire indication information sensed by the fire sensors and at least a portion of the plurality of fire diffusion retarded spray nozzle units for spraying fluid, And a control unit for controlling at least a part of the control unit.

According to the present embodiment, it is possible to minimize unnecessary property loss by not spraying water in all directions like a conventional sprinkler, and it is possible to install a fire diffusion delay device interlocked with the evaporative cooling device, It is economical because it is economical because it is economical because it can be economized because it can perform fire suppression and fire suppression in a wide area without using a high cost powder fire extinguisher.

Referring to FIG. 8, the fire diffusion delayed spray nozzle unit 110 and the fire diffusion delayed spray nozzle unit 110 are installed to overlap the spray ranges at regular intervals according to the diffusion of the mist. According to the embodiment illustrated in FIG. 8, adjacent fire retarding spray nozzle units 110 may be installed at intervals of 7 m such that the fluid mist spray range overlaps by about 1 m. Thus, according to the present embodiment, even when a fire occurs at the boundary of the spraying region of any one of the fire retarding spray nozzle units 110, since the spraying ranges overlap each other at the boundary portion of the spraying region, ≪ / RTI >

FIG. 9 is a view showing a state in which the fire retarding spray nozzle unit 110 according to the present embodiment is applied to a commercial market in a traditional market. Referring to FIG. 9, it can be seen that a spraying range of about 6 m is provided when the fire retarding spray nozzle unit 110 according to the present embodiment is applied 2 m before the entrance to a shop on a traditional market. In the traditional market, where the stores are densely packed and the floating population is high, there is a fear of loss of life and loss of property in the event of a fire, a range of about 6 m of fluid mist spray is provided. Therefore, it is possible to suppress the occurrence of fire and to suppress the spread of fire.

Fluid is provided to the fire diffusion retarder (100) through the fluid line (140). 1, the fluid pipe 140 may be a pipe dedicated to the fire diffusion delay unit 100, and may be provided with water or fire extinguishing liquid through an external pipe (not shown) . In an embodiment not shown, the fluid piping 140 may be a common piping of the evaporative cooling unit 400 and the fire diffusion delay unit 100, and may be supplied with water through an external piping (not shown) ).

The fire sensor 130 monitors a fire symptom and provides the detected fire symptom information to the control unit 300. In one embodiment, the fire sensor 130 may provide fire indication information to the control unit 300 wirelessly. In another embodiment, the fire sensor 130 may provide wired fire indication information to the control unit 300.

The solenoid valve 120 is controlled by the control unit 300 to shut off the fluid supplied from the fluid pipe 140 or to provide the spray nozzle 110 with the fluid. The spray nozzle 100 sprays a high-pressure fluid at a place where the fire sensor 130 providing the fire symptom information is located, thereby suppressing the fire or suppressing the fire spread.

The drain valve S removes the air contained in the fluid pipe 140 to smooth the flow of the fluid in the pipe and drains the fluid contained in the fluid pipe 140 to prevent freezing of the cold pipe. For example, the drain valve S is a solenoid valve, and the opening and closing of the drain valve S can be controlled by the control unit 300.

In one embodiment, the pump 200 may provide fluid to both the fire diffusion delay unit 100 and the evaporative cooling unit 400. However, the pump 200 may provide a higher fluid pressure to the fire diffusion delay unit 100 than the fluid pressure supplied to the evaporative cooling unit 400.

FIG. 2 is a view schematically showing the state of operation of the evaporative cooling unit 400, and FIG. 3 is a view schematically showing the flow diagram of the evaporative cooling unit 400. As shown in FIG. Referring to FIGS. 2 and 3, the evaporative cooling unit 400 includes a plurality of cooling mist spray nozzles 412 for spraying a mist-state fluid and a plurality of cooling mist spray nozzles 412 for providing or blocking the fluid to the plurality of cooling mist spray nozzles A mist spraying unit 410 including solenoid valves (not shown) controlled by the control unit, a plurality of blasting fans 422 for spraying a mist-state fluid to convect the air, and a solenoid valve (not shown) controlled by the control unit to provide or block the fluid to the fans.

In the embodiment shown in Fig. 3, the first cooling pipe P1 provided in the mist injection unit 410 and the second cooling pipe P2 provided in the convection portion 420 are shown as being separate from each other. However, according to the embodiment not shown, the mist ejection unit 410 and the convection portion 420 can share the same pipe.

In one embodiment, in the ejection fan 422 included in the convection section 420, the distance d1 between adjacent ejection fans may be 20m, and the distance d2 between the ejection fans located on opposite sides may be 10m . However, this is an embodiment, and can be modified and modified according to the environment of the place where the embodiment is installed.

In the high places adjacent to the ceiling of traditional markets, public facilities, arcades and warehouses, heat builds up and the temperature rises relatively. The evaporation cooling unit 400 injects a mist of mist into the mist spray nozzle 412 to lower the ambient temperature by using the evaporation heat, spray the fluid mist to the spray fan 422, Lower the temperature, suppress the rise of the relative humidity, and lower the sensation temperature.

In one embodiment, the cooling mist ejection unit 410 may further include a first drain valve S1 whose opening and closing are controlled by the control unit 300. [ The convection unit 420 may further include a second drain valve S2 whose opening and closing is controlled by the control unit 300. [ The first drain valve S1 and the second drain valve S2 are opened to remove the air present in the first cooling pipe P1 and the second cooling pipe P2 respectively in the pipe to smoothly supply the mist for cooling . In addition, in the wintertime when cooling is unnecessary, the fluid contained in the first cooling pipe (P1) and the second cooling pipe (P2) can be drained to prevent the pipe from being frozen. In one embodiment, the first drain valve S1 and the second drain valve S2 may be solenoid valves.

The control unit 300 receives the fire symptom information from the fire sensor 130 through the wired and / or wireless communication environment and controls the evaporative cooling unit 400 and the fire diffusion delay unit 100. In one embodiment, the controller 300 may be implemented as a microprocessor (MP) or a microcontroller unit (MCU). As another example, the controller 300 may be implemented by a computer.

An operation example of the fire diffusion delay device 10 according to the present embodiment will be described with reference to FIGS. 1 to 3. FIG. Before the fire occurs, the diffusion diffusion delay unit 100 does not operate and the evaporative cooling unit 400 operates to cool the installed place. As described above, the mist spraying unit 410 can perform cooling by spraying fluid mist at a place where the evaporative cooling unit 400 is installed, removing heat generated at the high spot by using evaporation heat, 420 may be used to cool the air by convection to lower the relative humidity and lower the bodily sensation temperature.

When a fire occurs, the fire sensor 130 detects heat and / or smoke, which is a sign of a fire, and provides fire symptom information to the control unit 300 through a wireless or wired communication network. In one embodiment, the control unit 300 having received the fire symptom information may notify the nearby fire station of the occurrence of the fire. For example, the control unit 300 can notify the occurrence of a fire through wired, wireless communication, a text message, or a social network service (SNS).

Upon receipt of the fire symptom information, the control unit 300 stops the operation of the evaporative cooling unit 400 and drives the fire diffusion delay unit 100. The controller 300 controls the solenoid valve of the fire diffusion delayed collision nozzles 110 disposed at a position corresponding to the position of the fire sensor 130 providing the fire symptom information among the plurality of fire sensors 130 And causes the fire diffusion delayed collision nozzles unit 110 to spray the high-pressure, high-speed fluid mist provided by the pump 200.

As described above, since each of the fire retardant collision nozzles 110 is disposed so as to overlap the injection range, the control unit 300 controls the fire diffusion adjacent to the position of the fire sensor 130 providing the fire warning information, All of the collider nozzles units 110 can control the solenoid valve to spray the fluid mist.

In order to spread the fire, the heat, oxygen, and fuel are required to be met, and the fire is diffused as it is supplied with the surrounding oxygen and reaches the ignition point of the raw material by high heat. However, the mist sprayed at high pressure in the fire retarding collider nozzles unit 110 minimizes the oxygen supply to the generating zone, instantaneously lowers the ambient temperature by the evaporative effect, the fine mist sprayed to the collider nozzles unit 110 penetrates into the lower ignition point or the space where the water does not close to evolve the fire or prevent the delay and diffusion.

If the fire sensor 130 no longer detects heat and / or smoke, it can be determined that the fire has been extinguished. If the fire sensor 130 does not provide the fire symptom information, the control unit 300 opens the valve S to discharge residual air such as air remaining in the fluid pipe 130. Then, the control unit 400 drives the evaporative cooling unit 400 to ventilate the ambient air. In addition, the fan 422 included in the convection unit 420 of the evaporative cooling unit 400 operates to discharge the smoke due to the occurrence of the fire to the outside using forced convection, thereby minimizing the damage caused by smoke.

According to the present embodiment, it is possible to minimize unnecessary property loss by not spraying water in all directions like a conventional sprinkler, and it is possible to prevent fire suppression and fire suppression in a wide area without using a high-cost powder fire extinguisher It is economical.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of illustration, It will be appreciated that other embodiments are possible. Accordingly, the true scope of the present invention should be determined by the appended claims.
