Description

Technical Field

[0001] The present application relates to the technical field of smoke exhaust ducts, and in particular to an aerogel smoke exhaust duct device. Background Art

[0002] The smoke exhaust duct is used as the ventilation duct in the smoke exhaust system. The smoke exhaust system adopts mechanical pressurized air supply or natural ventilation to prevent smoke from entering the evacuation passage and exhaust the smoke to the system outside the building. The smoke exhaust system has two main functions: one is to set up smoke prevention facilities in the evacuation passage and crowded areas to facilitate the safe evacuation of personnel; the other is to discharge the toxic and high-temperature smoke generated at the fire scene in time to eliminate obstacles to fire extinguishing.

[0003] Smoke control and exhaust systems are composed of air supply and exhaust ducts, pipe shafts, fire dampers, door switch equipment, supply and exhaust fans and other equipment. The smoke control system supplies air to the smoke-proof stairwell and its antechamber, the antechamber of the fire elevator room and the antechamber of the refuge corridor, the refuge floor and other parts to maintain a certain positive pressure to prevent smoke from invading and ensure evacuation safety. The current smoke control and exhaust ducts are relatively simple, most of which are naturally ventilated or equipped with a pressurized fan. The smoke exhaust effect is insufficient, which reduces the efficiency of smoke transportation. Therefore, in order to solve the above problems, we provide an aerogel smoke control and exhaust duct device. Utility Model Content
