In particular, large public welfare places have higher and higher requirements for environmental protection, and the muffled air ducts required for air purification, smoke exhaust, and fresh air series have become more and more widely used.
    The smoke prevention and exhaust system is composed of air supply and exhaust pipes, tube wells, fire dampers, door switch equipment, air supply and exhaust fans and other equipment. The smoke prevention system is set in the form of positive pressure in the stairwell. The smoke volume of the mechanical smoke exhaust system has a direct relationship with the smoke prevention zone. The smoke-proof facilities of high-rise buildings should be divided into smoke-proof facilities with mechanical pressurized air supply and natural smoke-exhaust facilities that can open external windows. The fire protection system shall be equipped with smoke prevention and exhaust equipment according to the "Code for Design of Fire and Smoke Exhaust of High-rise Buildings".

The smoke prevention system uses a mechanical pressurized air supply method or a natural ventilation method to prevent smoke from entering the evacuation passageway; the smoke exhaust system uses a mechanical smoke exhaust method or a natural ventilation method to exhaust the smoke outside the building. It can be divided into mechanical smoke exhaust system and natural smoke exhaust system. The mechanical smoke prevention and exhaust system is composed of air supply and exhaust pipes, tube wells, fire dampers, door switch equipment, air supply and exhaust fans and other equipment. The smoke prevention system is set in the form of positive pressure in the stairwell. The smoke volume of the mechanical smoke exhaust system has a direct relationship with the smoke prevention zone. The natural smoke prevention and exhaust system smoke-free stairwell front room or shared front room. When an open balcony, alcove, or open exterior windows with different orientations in the front room can be used to naturally emit smoke, the stairwell may not have smoke exhaust facilities.
