Background

The installation of air exhaust and smoke evacuation systems in buildings, such as underground garages, is generally required to meet relevant industry standards. For example, for exhaust systems, it is required that the distance from the upper edge of the inlet opening to the ceiling plane or roof is not more than 0.4 m; for the smoke exhaust system, the smoke exhaust port is required to be arranged on a ceiling or a wall surface close to the ceiling, and the smoke exhaust port is required to be arranged in the smoke storage bin.

In order to save cost and facilitate layout, most buildings adopt an air exhaust and smoke exhaust contract system, namely air exhaust at ordinary times and smoke exhaust at fire. Therefore, in the design process, the design of the air (smoke) exhaust port not only needs to meet the standard requirement of the air exhaust port, but also needs to meet the standard requirement of the smoke exhaust port, so that the arrangement of the air (smoke) exhaust port of the contract system is the key point and the difficulty point of the design of the smoke exhaust system.

At present, the conventional arrangement mode of the air (smoke) exhaust port is to arrange the air (smoke) exhaust port on the two sides of the main air duct, or to arrange the air (smoke) exhaust port on the top surface of the main air duct. However, this method is difficult to install in the beam space, and thus it is difficult to satisfy the requirement for the height of the upper edge of the tuyere. At the same time, this approach results in a limited amount of smoke being allowed from a single smoke outlet. Therefore, the conventional arrangement mode is difficult to meet the requirements of smoke exhaust and air exhaust.

Referring to fig. 1, the present invention provides a smoke exhaust duct 100. In addition, still provide an underground garage and exhaust system of discharging fume. The above-mentioned smoke exhausting and exhausting system includes a smoke exhausting and exhausting duct 100. Besides, the above-mentioned smoke exhausting and exhausting system generally further includes an air extractor set, and an air inlet end of the air extractor set is communicated with the smoke exhausting and exhausting duct 100 and performs air extraction through the smoke exhausting and exhausting duct 100. The smoke exhaust and air exhaust system is arranged in the underground garage and can be used for ventilating and exhausting smoke of the underground garage.

Referring to fig. 2, the exhaust duct 100 includes a main duct 110 and a branch duct 120. Wherein the main duct 110 extends in a first direction and the branch ducts 120 extend in a second direction. Also, the second direction is different from the first direction, i.e., the branch ducts 120 do not extend in the same direction as the main duct 110.

The main duct 110 and the branch duct 120 are hollow tubular structures, and may be linear or curved, for conducting airflow. The main duct 110 and the branch ducts 120 are generally made of metal, and may be in the shape of a circular tube, a square tube, or the like.

Further, the branch duct 120 is communicated with the main duct 110, and the outer wall of the branch duct 120 is provided with a smoke exhaust outlet 101 communicated with the inside of the branch duct 120. The branch pipes 120 and the main air pipe 110 may be integrally formed, or may be fixed and communicated by welding or the like. Air and smoke can enter the branch pipes 120 through the smoke exhaust vents 101 and be exhausted by the air extractor through the main air duct 110.

Specifically, in the present embodiment, the central axis of the main duct 110 intersects the central axis of the branch duct 120. The central axes of the main duct 110 and the branch duct 120 respectively pass through the centers of the main duct 110 and the branch duct 120, and are consistent with the extending directions of the main duct 110 and the branch duct 120.

That is, the central axis of the main duct 110 and the central axis of the branch duct 120 are located on the same plane. Thus, when the air flows from the branch ducts 120 are merged into the main air duct 110, the merging point of the air flows is located in the middle area of the main air duct 110, so that the disturbance of the air flows in the main air duct 110 can be reduced.

Referring again to fig. 1, a top beam 210 is disposed at the top of the underground garage, the main duct 110 is attached to the bottom of the top beam 210, and the branch ducts 120 extend toward the top of the underground garage.

Accordingly, after the main duct 110 is installed, the branch ducts 120 may be extended upward and into the gap between the top beams 210. Because the exhaust fume exhaust outlet 101 is positioned on the branch pipe 120, the installation in the beam space of the exhaust fume exhaust outlet 101 can be realized, so that the exhaust fume exhaust outlet 101 can be closer to the top of the underground garage, and the upper edge of the exhaust fume exhaust outlet 101 can meet the standard requirement of exhaust air.

Meanwhile, the distribution of the smoke exhaust and air exhaust port 101 on the branch pipe 120 is not limited by other factors, so that the volume of the branch pipe 120 can be fully utilized, and the Db value of the smoke exhaust and air exhaust port 101 is close to the thickness of the smoke layer to the maximum extent. Therefore, the amount of smoke allowed by the single smoke exhaust vent 101 can be significantly increased. In addition, the height of the smoke-blocking vertical wall can be reduced, and the net height of the smoke-blocking vertical bottom of the garage is improved. Therefore, the exhaust duct 100 can better satisfy the requirements of exhausting smoke and exhausting air simultaneously.

In the present embodiment, the main duct 110 and the branch duct 120 are linear, and the first direction is perpendicular to the second direction.

The main duct 110 and the branch ducts 120 cooperate to form an L-shaped structure. When the exhaust/exhaust duct 100 is installed, the main duct 110 may extend in a horizontal direction, and the branch duct 120 may extend in a vertical direction. On one hand, the installation is convenient; on the other hand, the branch pipes 120 extend vertically upward, so that the space occupied by the smoke exhaust duct 100 can be reduced.

Further, in the present embodiment, the smoke exhaust vent 101 is located on the side wall of the branch pipe 120. That is, after the installation of the exhaust duct 100, the opening direction of the exhaust outlet 101 may be directed to both sides.

In southern areas, air humidity is high and the temperature difference between morning and evening is large. Because the temperature difference between the inside and the outside is too large, when the outside humid and warm air enters the garage with lower temperature and meets condensation, the condensation phenomenon can be generated. When water droplets generated by condensation enter the exhaust system through the exhaust outlet 101, the system is damaged and the deterioration is accelerated. In this embodiment, the opening direction of the exhaust-smoke exhaust outlet 101 faces to both sides, so that water drops generated by condensation can be remarkably prevented from flowing into the pipeline through the exhaust-smoke exhaust outlet 101, and the service life of the exhaust-smoke exhaust system is effectively prolonged.

Further, in this embodiment, the branch pipe 120 is a hollow cube, and the smoke exhaust and air exhaust openings 101 are distributed on two opposite side walls of the branch pipe 120.

In this manner, the branch pipes 120 may intake air from two opposite directions. Moreover, the exhaust and air outlet 101 on the two side walls do not interfere with each other, thereby significantly improving the air intake efficiency.

Specifically, in the present embodiment, the smoke exhaust outlet 101 is covered with a single layer of louvers 121.

The louver 121 can be a structure formed by resin, plastic or metal, and the single layer louver 121 can further prevent water drops from entering the pipeline, so that the service life of the smoke exhaust and exhaust system is further ensured. In addition, because the dust is raised more in the underground garage when the vehicle travels, the single-layer shutter 121 can effectively reduce the dust entering the pipeline on the premise of ensuring the ventilation effect, thereby ensuring the sanitary environment of the smoke exhaust and exhaust system.

In the present embodiment, the smoke exhaust duct 100 further includes a regulating valve 130 for regulating the amount of intake air of the smoke exhaust outlet 101. The adjusting valve 130 can adjust the air inflow of the smoke exhaust outlet 101 to be large or small according to the requirement, thereby realizing uniform air exhaust.

Further, in the present embodiment, the adjusting valve 130 is disposed in the main duct 110. Therefore, one adjusting valve 130 can adjust the amount of air taken from all the smoke exhaust outlets 101 of the branch ducts 120 communicating with the main duct 110.

On one hand, the smoke exhaust and air exhaust openings 101 formed in the two opposite side walls of the branch pipe 120 can share one regulating valve 130, so that air volume can be uniformly regulated and exhausted, the number of the regulating valves 130 can be reduced, and the cost and the installation difficulty are reduced. On the other hand, the regulating valve 130 provided in the main duct 110 does not occupy the space in the vertical direction of the branch duct 120. Therefore, in a limited space, the size of the exhaust-smoke exhaust outlet 101 can be further increased, thereby facilitating the arrangement of the exhaust-smoke exhaust outlet 101 meeting the requirements.

In the above-mentioned exhaust and ventilation duct 100, after the main duct 110 is installed on the top of the building, the branch ducts 120 may extend upward and into the gap between the top beams 210. Because the exhaust fume exhaust outlet 101 is positioned on the branch pipe 120, the installation in the beam space of the exhaust fume exhaust outlet 101 can be realized, thereby ensuring that the height of the upper edge of the exhaust fume exhaust outlet 101 meets the requirement of the exhaust specification. Meanwhile, the distribution of the smoke exhaust and air exhaust openings 101 on the branch pipes 120 is not limited by other factors, and the volume of the branch pipes 120 can be fully utilized. Therefore, the amount of smoke allowed by the single smoke exhaust vent 101 can be significantly increased. It can be seen that the above-mentioned exhaust duct 100 better meets the requirements of exhausting smoke and exhausting air simultaneously.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
