Described PLC controller 9 is provided with " on & off switch ", with control system switching on and shutting down, and is provided with basic function display floater.
Operating principle of the present utility model and use step:
Pollutant in tunnel is mainly vehicle exhaust, due to its meeting nature floating that affects of autologous density and exhaust gas heat air-flow, therefore can form on top, tunnel foul atmosphere region.The roadway region of bottom 4 and the vent passages 3 on top are roughly separated (can not produce large impact to the natural ascending air of tail gas) by phase transformation and fire extinguishing furred ceiling, but can reduce the wind taking up in Vehicle Driving Cycle, the foul atmosphere on top, tunnel blown to roadway region, bottom 4 again.When fire smoke evacuation, operating principle is similar.The zone of action of simultaneously reducing strip encapsulation phase transformation and extinguish material housing 1, makes it only act on 4 regions, roadway region of bottom, increases its utilization rate.
System ring control operation in summer.When tunnel internal temperature higher (higher than 30 DEG C), 30 DEG C of the phase-change material 14(phase transition temperatures of phase transformation and extinguish material) undergo phase transition, absorb the waste heat in tunnel, to maintain the temperature in roadway region 4.In addition:
1), when the temperature in roadway region 4 is when outside 40 DEG C and tunnel, temperature sensing probe 16 is lower than 35 DEG C, or when the gas concentration probe 7 while ventilation reaches setting value, PLC controller 9 is controlled ventilation/smoke extractor exhaust fan 5 and is opened, to the outdoor new wind of sending in tunnel, to reduce the concentration of temperature in tunnel or pernicious gas.
2), when morning is when 4:00, temperature in tunnel is during still higher than 27 DEG C, and when outside tunnel, temperature sensing probe 16 is lower than 25 DEG C, PLC controller 9 is controlled ventilation/smoke extractor exhaust fans 5 and opened, to the outdoor new wind of sending in tunnel, so that strip encapsulation phase transformation and extinguish material housing 1 discharge phase transformation heat.
System ring control operation in winter.In the time that in tunnel, vehicle flowrate is large, 30 DEG C of the phase-change material 14(phase transition temperatures of phase transformation and extinguish material) absorb and store the waste heat in rising tail gas, in the time that the temperature in tunnel is lower, discharge this part heat.In addition when the temperature in roadway region 4 is lower than 5 DEG C, and when outside tunnel, temperature sensing probe 16 is higher than 7 DEG C, or when the gas concentration probe 7 while ventilation reaches setting value, PLC controller 9 is controlled ventilation/smoke extractor exhaust fan 5 and is opened, to the outdoor new wind of sending in tunnel, to improve temperature in tunnel or to reduce the concentration of pernicious gas.
The operation of system fire.When fire detector 6 detects fire, PLC controller 9 is controlled ventilation/smoke extractor exhaust fan 5 opened smoke-discharging patterns, discharges the fire smoke in tunnel; Control fire acousto-optic alarm 10 simultaneously and open, warning evacuating personnel is fled from.
Simultaneously, high temperature rising flue gas when fire makes to be arranged in strip encapsulation phase transformation and the foaming of extinguish material housing 1 inside and the calcium bicarbonate of extinguish material 13 and decomposes (60 DEG C start to decompose) one-tenth calcium carbonate, water and carbon dioxide, decompose the water producing and react generation bubble with frother, above-mentioned serial reaction makes the volume expansion of foaming and extinguish material 13, cause interior separation 15 film ruptures, foaming and extinguish material 13 directly contact with the large quantity of moisture in phase-change material 14, reaction is aggravation (volume further expands) further, strip encapsulation phase transformation and extinguish material housing 1 internal pressure reach after setting value, (calcium chloride hexahydrate can absorb heat and flame arrest each material, water, carbon dioxide, calcium carbonate and frother form fire foam) from its bottommost, jet 12 is set and sprays, the ignition point of falling bottom reaches the object of fire extinguishing.
The utility model has mainly utilized: 1, the principle of heat release is inhaled in phase transformation; 2, calcium chloride hexahydrate can absorb heat and the principle of flame arrest; 3, water, carbon dioxide, calcium carbonate and frother form the principle of fire foam.
PLC controller 9 is provided with " on & off switch ", with control system switching on and shutting down, and be provided with basic function display floater: " system ring control in summer running status ", " system ring control in winter running status ", " fire condition ", can show pop one's head in 16 temperature value of temperature sensing probe 8 in tunnel, the outer temperature sensing in tunnel.
In ventilation/smoke extractor exhaust fan 5, fire detector 6, gas concentration probe 7 while ventilating, tunnel, outside temperature sensing probe 8, fire acousto-optic alarm 10 and tunnel, temperature sensing is popped one's head in and 16 automatically controlled by PLC controller 9.After switching on power, by " on & off switch " on PLC controller 9, equipment can be realized automatic operation, and conversion operation operating mode, operates without user automatically.
In sum, the utility model is controlled the temperature in tunnel, harmful gas concentration and fire by phase transformation and fire-extinguishing integrated material and ventilation/smoke extractor exhaust fan, can provide than natural ventilation/smoke evacuation and mechanical ventilation/fume exhausting type and the higher comfort level of fire extinguishing system that arranges separately; During due to fire, fully automatic operation fire extinguishing, does not need personnel to operate in scene of fire, so safe and reliable, automaticity is high; Again simple by integrated system, occupy little space, can collect residual heat of tail gas of automobile, cost is low, energy-efficient, good looking appearance, highly integrated, noise is low, economic and practical.
