Intelligent tunnel fire smoke control system and working method and installation method of intelligent tunnel fire smoke control system

Abstract

The invention discloses an intelligent tunnel fire smoke control system and a working method and installation method of the intelligent tunnel fire smoke control system. The intelligent tunnel fire smoke control system comprises a smoke exhaust system, a smoke control system, a supporting system and an intelligent control system, wherein the smoke exhaust system comprises a smoke exhaust pipeline,a smoke exhaust damper and a smoke exhaust fan; the smoke control system comprises a smoke control water pipe, a spray head and a water supply pipe; the supporting system enables the smoke exhaust system and the smoke control system to be arranged in the middle of a tunnel vault; the intelligent control system comprises an intelligent valve and a control center; the intelligent valve comprises anelectromagnetic attraction device, a temperature sensor, a smoke transducer and an alarm; the temperature sensor and the smoke transducer sense the fire and give an alarm to people inside and outsidetunnel, the electromagnetic attraction device opens the smoke exhaust damper, and the control center starts the smoke exhaust damper and the spray head, so that the fire field temperature inside thetunnel is reduced, the smoke is exhausted quickly, time is saved for the people inside the tunnel, and the survival rate of people is improved; and the intelligent tunnel fire smoke control system hasan automatic trigger function, so that the reaction time of the system is reduced. According to the working method and installation method of the intelligent tunnel fire smoke control system, the installation process is simple, and the working efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of tunnel fire protection, and in particular relates to an intelligent control system for tunnel fire smoke and its working method and installation method. Background technique [0002] With the rapid development of my country's economic construction, the scale of new tunnels is rapidly expanding, and the number of long tunnels is increasing rapidly. The space in the long tunnel is narrow and relatively closed, and the exits for evacuation are limited. Once a fire breaks out, the tunnel will be filled with smoke quickly, and the large amount of toxic smoke produced by the fire cannot be quickly discharged out of the tunnel, which may cause a large number of casualties and property losses. . [0003] In addition, at present, the ventilation in most domestic tunnels adopts longitudinal ventilation. In the event of a fire, the operation of the fan in the tunnel will cause the smoke to spread rapidly along the ...
