Mutual-communication type high-rise building smoke exhausting system

Abstract

The invention discloses an intercommunicating smoke exhaust system for high-rise buildings, which comprises a tube well (1), an air supply port (2), a top cover (3) and a smoke outlet (4), and also includes a smoke exhaust fan (5), wherein, The air supply port (2) is located at the lowermost end of the tube well (1), the top cover (3) is located at the uppermost end of the tube well (1), the smoke outlet (4) is located at each floor in the tube well (1), and the exhaust fan (5 ) is installed between the top cover (3) and the tube well (1). A fan is installed horizontally at the bottom of the tube well (1), and fire-proof and anti-corrosion materials are laid on the inner surface. A smoke exhaust fire damper is installed at the air supply port (2). The device of the invention can discharge the smoke in a high-rise building in a concentrated manner, prevents the smoke from pouring backwards or running around, and improves the smoke exhausting effect.

Description

technical field [0001] The invention relates to the field of smoke exhaust for high-rise buildings, in particular to an intercommunicating smoke exhaust system for high-rise buildings. Background technique [0002] The smoke exhaust system is indispensable in today's high-rise buildings. It not only ensures the internal environment of the building, but also plays a safety role. At present, the smoke exhaust systems of many high-rise buildings are only designed with a smoke exhaust channel. Potential safety hazards. The smoke exhaust system of some high-rise buildings is also designed with mechanical smoke exhaust facilities. Because the building is taller and the simple air supply device cannot meet the good smoke exhaust effect, there may be smoke backflow or chaos, which greatly affects the high-rise buildings. The internal environment of the building has great potential safety hazards. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the ...
