Description

Water spray nozzle for water based fire compartment wall

The present invention relates to a spray device for forming a water protection film, and more specifically, it is possible to form a water protection film to block the fire generation section from other sections in the event of a fire in a closed long passage structure such as a tunnel. To a spray device.

In general, long aisle structures such as tunnels and cavities are quite long, so that people can evacuate at certain intervals in order to prevent fires, and quickly release smoke and heat generated by fires to the outside. Ventilation and fire extinguishers to extinguish fire are essential.

Even though equipments are prepared for the occurrence of a fire, it is not easy to extinguish a fire because of the long passage structure such as a tunnel.

In particular, since the flame, smoke and toxic gases generated in a fire are rapidly spread and dispersed through the tunnel, the tunnel serves as a passage for moving the flame, smoke and toxic gases. Therefore, if the flame, smoke and toxic gases are not discharged quickly to the outside, the smoke obscures the vision, and the toxic gases cause difficulty in breathing, making it difficult for people to evacuate. In addition, this makes it difficult to transport the equipment and personnel for extinguishing fire from the outside, and thus, if the fire suppression fails initially, a large number of casualties and physical damage may occur.

Fire extinguishing equipments installed in existing tunnels are mostly mobile extinguishers, horizontal or downward spray water spraying devices, and can be used to remove flames caused by fire by directly injecting them into the fire source. There was always a risk of injury due to failure to cut off tears and smoke.

Therefore, in order to protect human life from heat and smoke generated in a fire, a protective film that can prevent heat and smoke from spreading along the tunnel is required by blocking a certain section in which the fire is generated from an unfired section.

However, these barriers should be able to block the movement of heat and smoke without affecting the movement of people or means of transportation.

The present invention has been made in view of the above problems, by forming a water protection membrane that can prevent the spread of flame, smoke and toxic gases by blocking the fire occurrence section of the long passage structure such as tunnels and the non-fire section The purpose is to provide a spray device.
