Problems solved by technology
[0003] Existing tunnel ventilation basically uses jet fans to ventilate the tunnel. When a fire breaks out in the tunnel, the jet fan will blow the smoke and dust from the fire point to the direction where the fire does not occur, so that the tunnel is full of smoke and dust. The spread of the fire will cause great difficulty and harm to personnel escape and rescue, and the fire will easily burn out the cables of the jet fan, causing the power supply of the jet fan to be interrupted and affecting the ventilation in the tunnel

The invention relates to the technology of tunnel ventilation and discloses a solar thermal flow tunnel ventilation system. The solar thermal flow tunnel ventilation system comprises a ventilating pipe in a tunnel, a heat collection shed, a thermal flow chimney and a ventilation connecting pipe, wherein the heat collection shed and the thermal flow chimney are disposed outside the tunnel, and the ventilation connecting pipe is communicated with the ventilating pipe in the tunnel, and the heat collection shed. An air inlet of the ventilating pipe is communicated with the tunnel. An air outlet of the ventilating pipe is communicated with an air inlet of the ventilation connecting pipe. An outlet of the ventilation connecting pipe is communicated with an air inlet of the heat collection shed. An air outlet of the heat collection shed is communicated with an air inlet of the heat flow chimney. An air outlet of the heat flow chimney is communicated with the atmosphere. By the solar thermal flow tunnel ventilation system which is energy-saving, consumption-reducing, safe and reliable, solar radiation heat can be converted into kinetic energy for air circulation, and accordingly tunnel ventilation is achieved.
Description
technical field [0001] The invention relates to tunnel ventilation technology, in particular to a solar heat flow tunnel ventilation system. Background technique [0002] With the rapid development of expressways in our country, the large tunnels of expressways in mountainous areas are also increasing. The length of large tunnels is long, and its operating costs, such as ventilation, lighting and other electricity costs, have gradually become a heavy burden for many operating units. Assuming that ventilation is considered according to the two-way tunnel, about 6 jet fans are required to be installed per kilometer of tunnel. The power of each jet fan is considered to be 30 kilowatts, and the ventilation time is about eight hours a day. Based on this, the consumption of only ventilation per kilometer of tunnel per month is calculated. The electricity bill is about 30,000 yuan. According to incomplete statistics, there are more than 26 million kilometers of road tunnels opene...
