Description

Technical Field

[0001] This utility model relates to the field of smoke exhaust in underground buildings, and in particular to a new type of smoke control and exhaust equipment for underground buildings. Background Technology

[0002] With the acceleration of urbanization and the in-depth development of underground space, the number and scale of underground buildings (such as subways, underground shopping malls, parking lots, and civil defense projects) are constantly expanding. However, due to their closed nature, poor ventilation, and difficulty in evacuation, underground buildings are prone to reduced visibility and sudden temperature rise due to smoke accumulation during fires, which seriously threaten people's lives and increase the difficulty of fire rescue. Therefore, efficient and reliable smoke control systems have become the core element of fire safety design for underground buildings.

[0003] Currently, smoke control and exhaust systems in underground buildings mainly rely on high-temperature fire-fighting smoke exhaust fans. These fans vent the dense smoke from inside the building to the outside, creating favorable conditions for the evacuation and relocation of trapped personnel. However, the dense smoke contains a large number of dust particles. When the smoke exhaust fan is operating, large dust particles can easily enter the fan, affecting its operation and smoke extraction efficiency. Therefore, we propose a new type of smoke control and exhaust system for underground buildings to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of smoke control and exhaust equipment for underground buildings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel smoke control and exhaust system for underground buildings includes a filter housing. A smoke exhaust fan is fixedly connected to one side of the filter housing. A top cover is provided on the upper surface of the filter housing, and a cleaning valve is installed on the upper surface of the top cover. Two sets of mounting slots are fixedly connected to the inner wall of the filter housing. A filter assembly is installed inside each set of mounting slots. A cleaning pipe is provided between the two filter assemblies. Two sets of cleaning nozzles are fixedly connected to the outer surface of the cleaning pipe. A connecting pipe is fixedly connected to the outer surface of the cleaning pipe. The top end of the connecting pipe passes through the top cover and is connected to the bottom end of the cleaning valve.

[0007] In a further embodiment, the output end of the exhaust fan is fixedly connected to an exhaust pipe, one end of the exhaust pipe is threadedly connected to a protective end cap, and a rotating rod is fixedly connected to the outer surface of the protective end cap.

[0008] In a further embodiment, the upper surface of the top cover is fixedly connected to two handles, the outer surface of the top cover is fixedly connected to two sets of fasteners, and the outer surface of the filter shell is fixedly connected to two sets of hooks, each hook engaging with a fastener.

[0009] In a further embodiment, the filtering assembly includes a filter frame installed inside a mounting slot, the filter frame having a filter screen installed inside.

[0010] In a further embodiment, a protective grille is installed on one side of the filter housing by screws, and a drain pipe is fixedly connected to the outer surface of the filter housing.

[0011] In a further embodiment, a base is fixedly connected to the bottom surface of the filter housing, the bottom end of the exhaust fan is connected to the upper surface of the base, and two sets of mounting holes are provided on the upper surface of the base.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device uses two sets of detachable filter components to form a stepped filtration system. The combination design of the filter frame and filter screen can effectively intercept smoke and dust particles of different sizes, significantly reducing the risk of dust accumulation in the exhaust fan and ensuring long-term stable operation of the equipment. A ring-shaped flushing network is formed by the cleaning pipe and multi-directional cleaning nozzles. The filter components can be flushed periodically through the external cleaning valve. With the bottom drain pipe, automatic slag discharge is achieved, solving the problem of manual cleaning of filter screens that are clogged in traditional exhaust equipment.

The integrated design of the exhaust fan 10 and the filter system ensures that it can maintain continuous operation in high-temperature flue gas environments.

[0025] The working principle of this utility model is as follows:

[0026] In use, the smoke exhaust device is installed at the ventilation location of the underground building. Then, the smoke exhaust pipe 11 is connected to one end of the smoke exhaust fan 10, and one end of the smoke exhaust pipe 11 is installed outdoors. The power supply of the smoke exhaust device is turned on. When the smoke exhaust device is running, the two filter components 9 in the filter housing 1 can filter large particles in the smoke and dust, preventing them from entering the smoke exhaust fan 10 during exhaust. The cleaning pipe 18 is connected to the bottom of the top cover 8 through the connecting pipe 19. The cleaning valve 15 above the top cover 8 controls the multiple cleaning nozzles 17 on the cleaning pipe 18 to periodically backwash the filter components 9.
