Description

Technical Field

[0001] The utility model relates to the field of ship equipment, in particular to a multi-connected smoke exhaust structure arranged in the hangar of a large ship. Background Art

[0002] The purpose of the smoke exhaust pipe is to discharge the indoor soot to the outside through a ventilation machine. Since the soot often adheres to the pipe, the smoke exhaust pipe needs to be cleaned frequently. The smoke exhaust pipe has a wide range of applications, including hotels, factories, and so on.

[0003] A smoke exhaust system is usually arranged in the ship hangar, which is suitable for quickly discharging the internal smoke when a fire occurs in the ship hangar. The smoke exhaust system includes: a smoke exhaust passage extending along the length direction of the tunnel and a plurality of smoke exhaust ports. The smoke exhaust ports are communicated with the smoke exhaust passage. The smoke in the ship hangar enters the smoke exhaust passage through the smoke exhaust ports and then is discharged from the air shaft on the smoke exhaust passage. For a large ship hangar, however, due to the layout environment in the ship hangar, effective smoke exhaust cannot be achieved in the ship hangar. The smoke exhaust structure in the large ship hangar consists of a duct fan, an axial flow fan, a pipeline, etc. The main function is to discharge the smoke in the passage after the smoke is generated and restore the visibility in the cabin. Mechanical ventilation is adopted, with natural air intake / mechanical air intake for ventilation. This structure layout cannot effectively and quickly exhaust smoke, and some structures cannot be automatically controlled. Summary of the Utility Model
