AI Technical Summary

Technical Problem

Existing fire-fighting ventilation systems are inefficient, risky, dependent on manual operation, and prone to causing secondary pollution, and cannot effectively remove pollutants from large spaces or complex buildings.

Method used

The intelligent exhaust system, which combines a central control unit with an environmental detection module, achieves fully automated zoned priority exhaust by monitoring and dynamically controlling electric valves, exhaust fans, and air supply devices in different zones. It also treats toxic gases with a filtration and purification device.

Benefits of technology

It achieves fully automated ventilation after a fire, reducing human risk, shortening evacuation time, eliminating the risk of misoperation and pollutant spread, and ensuring safe and efficient removal of smoke and toxic gases.

Abstract

The application discloses a kind of fire disaster post-clearing empty exhaust system and exhaust method, in which, a kind of fire disaster post-clearing empty exhaust system, including central control unit, exhaust host, main air duct, several exhaust branch pipes, environment detection module and air supply device.Exhaust host is electrically connected with central control unit, for providing exhaust power.Main air duct is connected with the outlet of exhaust host.One end of exhaust branch pipe leads to a separate partition of building, and the other end is communicated with main air duct by electric exhaust valve.Environment detection module is arranged in each separate partition, for monitoring the environmental parameters in the partition, and is connected with central control unit.The application can realize the whole process automation of post-disaster exhaust process, greatly reduces the need of firefighters exposed to dangerous environment, reduces the dependence on manual experience;Dynamic exhaust strategy is adopted, which greatly shortens the overall emptying time, and at the same time, can fundamentally eliminate the risk of misoperation combustion-supporting and pollutant diffusion.
