Description

Technical Field

[0001] The utility model relates to a tunnel refuge system, in particular to a tunnel fire personnel refuge system. Background Art

[0002] Tunnels are passages for various transportation equipment. They are relatively sealed inside and are long, making it inconvenient for people to pass through. Once a fire occurs inside a tunnel, a large amount of toxic smoke and high-temperature hot smoke will be generated, making it difficult for people to evacuate and put out the fire. Therefore, it is necessary to set up an escape area inside the tunnel to facilitate the escape of people inside the tunnel in the event of a fire.

[0003] In existing highway tunnels, a pedestrian crossing connecting two adjacent tunnels is usually set up at a certain distance. When a fire occurs in a tunnel, refugees can escape to the adjacent tunnel through the pedestrian crossing. However, for some tunnel scenarios where adjacent tunnels are far apart or adjacent tunnels are not at the same height, the increase in pedestrian crossings also greatly increases the difficulty of escape for refugees. At the same time, there is another way of refuge in existing highways, which is to design a refuge room next to the tunnel. When a fire occurs, people inside the tunnel can enter the refuge room; the existing refuge room is usually separated from the tunnel by a fire door, which can prevent the fire and toxic substances such as smoke in the tunnel from entering the refuge room, but it also isolates the air inside the refuge room; this results in poor ventilation in the refuge room, and the safety of escapees cannot be guaranteed after entering the refuge room. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a tunnel fire personnel refuge system, which solves the problem of poor ventilation effect in the existing refuge room.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A tunnel fire personnel refuge system comprises a fire tunnel and a non-fire tunnel; a fan room is arranged on one side of the non-fire tunnel, an air outlet of the fan room is connected to a carbon monoxide adsorption chamber; a static pressure box is connected to the air outlet of the carbon monoxide adsorption chamber; the static pressure box is connected to a refuge chamber through an air duct; and the refuge chamber is connected to the fire tunnel.

[0007] In this solution, the fan room blows air to the carbon monoxide adsorption chamber, which filters the air to remove toxic gases; the filtered air flows to the static pressure box to eliminate the air dynamic pressure, increase the static pressure, and then blows to the refuge room through the air duct, providing fresh and harmless air for the escapees in the refuge room, ensuring the safe evacuation of the escapees.

[0008] Furthermore, an air inlet is provided on the side of the fan room close to the non-fire tunnel, and the fan room is connected with the non-fire tunnel through the air inlet; an air outlet is provided on the side of the fan room close to the carbon monoxide adsorption chamber, and the fan room is connected with the carbon monoxide adsorption chamber through the air outlet; an axial flow fan is provided inside the fan room, and the blowing end of the axial flow fan is arranged toward the air outlet.

[0009] In this solution, an axial flow fan is arranged in the fan room, and air pressure is provided by the axial flow fan; the blowing end of the axial flow fan is arranged toward the air outlet, so that the air provided by the axial flow fan can be delivered into the carbon monoxide adsorption chamber to the greatest extent.

[0010] Furthermore, an activated carbon adsorption box is arranged in the carbon monoxide adsorption chamber, the air inlet of the activated carbon adsorption box is connected to the air outlet of the fan room, and the air outlet of the activated carbon adsorption box is connected to the static pressure box through a ventilation pipeline.

[0011] In this solution, when the air provided by the axial flow fan passes through the activated carbon adsorption box, the activated carbon inside the activated carbon adsorption box adsorbs the toxic gas in the air to ensure that clean air is blown into the refuge room; at the same time, it can also prevent the smoke inside the fire tunnel from entering the non-fire tunnel through the pedestrian crosswalk, and being sucked into the refuge room by the axial flow fan, thereby causing harm to the people in the refuge room.

[0012] Furthermore, the air duct is arranged at the top of the refuge chamber; one end of the air duct is connected to the air outlet end of the static pressure box; an air outlet is arranged at the bottom of the air duct, and the air duct is connected to the refuge chamber through the air outlet.

[0013] In this solution, when the air passes through the air duct and passes from the air outlet to the refuge room, it is blown down from the top of the refuge room, so that the air is distributed more evenly inside the refuge room.

[0014] Furthermore, a diffuser is installed in the tuyere.

[0015] In this solution, the diffuser can disperse the air at the air outlet to make the air supply flow more uniform and gentle.

[0016] Furthermore, a vestibule is provided on one side of the fire tunnel close to the refuge chamber; and a vestibule fire door is provided on the passage between the vestibule and the refuge chamber.

[0017] In this plan, while the escapees pour into the refuge room, some of them can take refuge briefly in the antechamber, which can act as a buffer and prevent the escapees from crowding each other. At the same time, necessary fire-fighting equipment and medical equipment can be placed inside the antechamber for use in emergencies.

[0018] Furthermore, a tunnel fire door is provided on the passage between the front room and the fire tunnel.

[0019] In this solution, the tunnel fire door can prevent the fire and smoke inside the fire tunnel from spreading to the antechamber and refuge room, thereby ensuring the safety of the people inside.

[0020] Furthermore, two antechambers are provided, and the two antechambers are respectively arranged on both sides of the refuge chamber.

[0021] The beneficial effects of the utility model are:

[0022] In the tunnel fire personnel refuge system provided by the utility model, a fan room is set to provide air for the refuge room, and a carbon monoxide adsorption chamber is set on the air flow path to adsorb toxic substances carried in the air, ensuring that the air sent into the refuge room is clean air for escapees to breathe. In addition, the wind pressure is provided by the fan room. Under the action of the wind force of the fan room, the air pressure in the refuge room is higher than the air pressure in the front room, and the air pressure in the front room is higher than the pressure in the fire tunnel. Therefore, it can better suppress the intrusion of smoke into the front room and the refuge room, further ensuring the safety of people inside the refuge room. BRIEF DESCRIPTION OF THE DRAWINGS
