Abstract

The invention discloses an air curtain smoke prevention and exhaust system for a tunnel and a method for preventing and exhausting smoke of the tunnel by using same. The tunnel is a bidirectional lanetunnel, wherein an interlayer is arranged between lanes. The tunnel comprises a PC (Personal Computer), a controller, an air inlet channel, an air outlet channel, a monitoring unit, an alarm unit anda plurality of air curtain units; the air inlet channel and the air outlet channel are arranged at the lower part of the tunnel interlayer side by side, and two ends of the air inlet channel and theair outlet channel correspondingly communicate with the outside; the monitoring unit comprises a plurality of image type fire detectors; the alarm unit comprises a plurality of fire alarms which are arranged in the tunnel and connected with the controller; the tunnel is divided into a plurality of equidistant sections which are internally provided with air curtain units; an each air curtain unit comprises a microprocessor, an air inlet chamber, an air discharge chamber, an air-out assembly and an exhaust assembly. The system is capable of detecting the conditions in the tunnel at any time, timely alarming and carrying out air curtain smoke removal under the condition that a large amount of smoke is generated in case of fire and the like, and avoiding casualties and property loss to the maximum.

Description

technical field [0001] The invention relates to an air curtain smoke prevention and exhaust system for tunnels and a method for tunnel smoke prevention and exhaust using the system. Background technique [0002] A tunnel refers to a channel dug out of an existing building or earth-stone structure. It is an engineering building buried in the ground and is a form of human use of underground space. However, since only two ends of the tunnel are connected to the outside world, once a tunnel fire occurs, it will not only damage property, but also cause difficulties in evacuation and fire fighting, and even cause casualties. Therefore, how to quickly and accurately detect fires and deal with them in time is the key to quickly controlling fires, rescuing personnel and reducing losses. Contents of the invention [0003] The purpose of the present invention is to solve the above technical problems and provide an air curtain smoke prevention and exhaust system for tunnels. The syst...
