Description

Technical Field

[0001] The utility model relates to the technical field of fire protection engineering, in particular to a smoke exhaust device for fire protection engineering. Background Art

[0002] In construction projects, the toxic smoke produced by fires often causes the greatest harm to the human body. Therefore, buildings need to be equipped with fire smoke exhaust ducts. Fire smoke exhaust ducts are mostly connected to the room through internal pipes, and the smoke in residential or commercial buildings is extracted by fans, and then discharged to the outdoors. Some existing fire smoke exhaust ducts are equipped with cleaning components inside, which can scrape and clean the inner wall of the smoke exhaust duct, but some internal pipes are vertically arranged. When the cleaning component scrapes the waste horizontally through the internal pipe, it will fall into the room through the shutters of the internal pipe, polluting the indoor environment. It is not convenient to clean the inner wall of the fire duct while protecting the room. Moreover, most of the smoke will float on the top wall of the smoke exhaust duct and be discharged. The dust adhesion on the top wall of the smoke exhaust duct is the most serious, and the dust is very sticky. It is not convenient to clean the dust adhered to the top wall of the smoke exhaust duct, and it is inconvenient to use. Utility Model Content
