System and method for independently carrying out natural ventilation of tunnel through solar air pump

Abstract

The invention discloses a system and a method for independently carrying out natural ventilation of a tunnel through a solar air pump. The system comprises a ventilation shaft arranged on a mountain above the tunnel in a penetration manner, wherein a sola air pump system is arranged at the outlet end of the ventilation shaft; the sola air pump system is capable of heating the air of the outlet end of the ventilation shaft and pumping polluted air in the tunnel out via negative pressure formed after the hot air quickly flows out of the ventilation shaft; the solar air pump system comprises a solar water heater unit and a chimney; the solar water heater unit is arranged on the mountain and constituted by a plurality of parallel solar water heaters; the chimney is connected to the outlet end of the ventilation shaft; a heat exchanger is arranged in the chimney; the outlet end of the solar water heater unit is connected to the inlet end of the heat exchanger; the outlet end of the heat exchanger is connected to the inlet end of the solar water heater unit. According to the system and the method, the cooperation of a power-driven ventilator is not needed; through heat energy storage of intermediate medium water, the ideal effect of independently carrying out natural ventilation of the tunnel under the condition without power consumption is ensured.

Description

technical field [0001] The invention relates to a tunnel ventilation system, in particular to a solar wind pump independent tunnel natural ventilation system and method. Background technique [0002] With the development of the country's economy, the national expressway mileage has reached 111,900 kilometers, ranking first in the world. As an important type of structure, highway tunnels can not only shorten the highway mileage, ensure the best alignment, improve technical standards, facilitate driving, but also effectively prevent bad weather and adverse geological disasters, improve driving safety, and at the same time better communicate with The local environment is coordinated and the natural landscape is preserved, so it has been widely used. According to statistics, as of the end of 2014, there were 12,404 highway tunnels across the country with a total length of 10.7567 million meters, including 626 super-long tunnels with a total length of 2.7662 million meters. At ...

Problems solved by technology

[0008] At present, the direct use of wind energy or geothermal energy to form negative pressure in the ventilation shaft to increase the natural ventilation can not be implemented due to its difficulty in obtaining or low efficiency, so the effective use of solar energy as a way to enhance the negative pressure and strengthen natural ventilation to achieve energy saving and reduction. platoon becomes its only option
