Description

Technical Field

[0001] This invention relates to the field of fire protection technology, and more specifically, to a method and device for controlling smoke exhaust in building fire protection systems. Background Technology

[0002] As the number of buildings in cities increases year by year, the fire hazard of buildings has become increasingly prominent. In the event of a fire, elevator shafts and pipe shafts act like large chimneys, creating strong drafts that cause smoke to rise rapidly, making escape extremely difficult. Statistics show that carbon monoxide poisoning or other toxic fumes account for 40% to 50% of all fire-related deaths. Smoke contains various toxic gases such as carbon monoxide and nitrogen monoxide; when the concentration of these gases exceeds the physiologically permissible maximum, it can cause poisoning and death. Furthermore, particulate matter in smoke is also harmful. Due to gas diffusion, smoke particles can enter the lungs, adhere to and accumulate on the alveolar walls, causing respiratory diseases and increasing the mortality rate from heart disease, posing a direct threat to human health.

[0003] Currently, the most widely used method for smoke extraction during building fires is to open the smoke exhaust valves and use smoke exhaust fans to expel the smoke collected at each valve.

[0004] However, during the operation of smoke exhaust fans, they are often operated at the highest power, i.e., the maximum smoke exhaust volume. At the same time, the actual smoke exhaust volume of the smoke exhaust fan is greatly affected by the internal building structure, making the smoke exhaust process untargeted, which in turn leads to the ineffective removal of smoke from some areas of the building. Summary of the Invention
