The present invention relates to the removal of smoke and toxic gas in accordance with the fire, and more specifically, the sprinkler and the sprinkling function to provide a function to inhale and remove the heat and toxic gases due to the fire with the spraying function to extinguish the fire. It relates to a smoke and toxic gas removal device having.

Sprinklers are a means of early extinguishing a building fire by automatically or manually releasing water from a pipe installed near the ceiling in the event of a fire. However, in the event of a fire, more casualties are caused by inhalation of smoke (toxic gases, fine dust) than by burns.

Therefore, even if the sprinkler is operated and the fire is initially suppressed, there is no practical way to deal with the toxic gas generated by the fire unless a flue gas facility for discharging the smoke and the toxic gas into the atmosphere is installed. Therefore, although there is a difference in degree, there is a problem that the anxiety about the damage to life due to smoke (toxic gas, fine dust) is always present even if the sprinkler is installed.

On the other hand, in the case of fire, smoke and toxic gases are discharged to the air, which are installed in apartments, building emergency stairs, and various tunnels, and devices called various smoke control devices in the current fire-fighting laws are strictly speaking smoke and toxic gases. It is a device corresponding to a flue gas exhaust system that discharges gas into the atmosphere. In other words, it is not a device that removes smoke and toxic gas as the term of the smoke removal device, but merely a device that discharges smoke and toxic gas into the atmosphere.

Such a device can be obtained by releasing smoke and toxic gases to the outside, but since the smoke and toxic gases themselves cannot be removed, air pollution caused by smoke and toxic gases cannot be avoided.

The present invention has been made in the technical background as described above, the object of the present invention is to sprinkler and smoke removal to effectively remove smoke and toxic gases so as to prevent the risk of toxic gases with early suppression of fire. It is to provide a device.

As shown in Figure 1, the smoke control sprinkler according to the embodiment of the present invention is connected to the pipe portion 101 for supplying water in the event of a fire, the frame (110_1, 110_2), the pipe portion ( Nozzle 112 for injecting water supplied from 101, a mixing chamber 120 in which water and smoke are injected through the nozzle 112, and a heat sensitive part fixed to seal the nozzle 112 normally ( 140, a sealing unit 130 positioned between the thermal part 140 and the nozzle 112, and a reflector 150 that disperses and discharges the smoke and water mixed in the mixing chamber 120.

The frames 110_1 and 110_2 and the mixing chamber 120 are usually made of a metallic material, and smoke and toxic gas generated in a fire are sucked through a gap between the upper portion 110_1 of the frame and the mixing chamber 120.

The heat sensitive portion 140 may be a melted heat sensitive portion formed by containing a small amount of metal melted at a set temperature, or a burstable heat sensitive portion composed of a glass bulb containing a small amount of liquid having good thermal expansion.

1 and 2, the inside of the nozzle 112 is provided with a rotating blade 114 for forming a vortex flow in the water sprayed through the nozzle 112. Due to this rotating blade 114, the flow of water supplied from the pipe portion 101 is converted into a vortex flow in a straight flow and is discharged through the nozzle 112.

The mixing chamber 120 uses a Venturi effect to suck smoke and toxic gas without dissipating extra energy and to dissolve or trap in the water discharged through the nozzle 112 to remove it.

When the fluid moves in a horizontal plane, ie there is no change in potential energy, according to Bernoulli's theorem, a decrease in fluid pressure means an increase in flow rate. For example, when fluid flows through a conduit of varying cross sectional area lying on a horizontal plane, the flow rate increases as the cross sectional area of the conduit decreases. Therefore, the pressure at which the fluid acts on the conduit becomes the smallest at the portion where the cross-sectional area of the conduit is minimum. As a result, the pressure inside the mixing chamber is reduced, so that the external gas is sucked in.

The closed sprinkler opens the normally closed inlet by heat from the fire. To this end, the fuse assembled using the special alloy's melt fuse or glass bulb starts to change at the set ambient temperature.

Sprayed toward the inlet of the Mixing Diffuser 120, a negative pressure, as described in Bernoulli's theorem, is generated in the space between the nozzle 112 and the Mixing Chamber 120, resulting in a vacuum. ) Is formed and suction is possible.

The mixing chamber 120 is formed to have a space shaped like a ring donut 122 in the center to generate vortices through a vortex phenomenon so that smoke and water can be mixed more efficiently.

In the event of a fire, smoke moves to the ceiling above the room, increasing the pressure of the hot air on the room's ceiling. The smoke layer, which is hotter, lighter and higher pressure than the air and rises to the ceiling due to the fire, is designed to be sucked into the corrugated venturi tube structure automatically without any additional equipment because the pressure flows from the high place to the low place. will be.
