Problems solved by technology

[0002] In the long mountain tunnels, the driving vehicles will continuously emit harmful exhaust gas and smoke. When the concentration of harmful exhaust gas and smoke exceeds a certain value, it will cause harm to the drivers and passengers, affecting their health and driving safety.
Therefore, in order to ensure the hygienic standards of the air environment required for the normal operation of mountain tunnels, the mountain tunnels should be ventilated, and natural ventilation in longer mountain tunnels cannot achieve the purpose of purifying the air quality in the mountain tunnels

Embodiment 1

[0014] Example 1 A method for realizing an air purification system in a mountain tunnel: 1) Buried the first ventilation duct 1 and the second ventilation duct 2 along the length of the tunnel under the road of the mountain tunnel; the first ventilation duct 1 and the second ventilation duct 2. Plastic pipes with slightly higher strength can be used, and pipes made of concrete can also be used. 2) In the middle of the road in the mountain tunnel, hollow columns 3 with air outlets are erected at regular intervals along the length of the tunnel. The hollow columns 3 are preferably erected in the middle of the road in the tunnel to facilitate the passage of vehicles. Hollow columns can be cast from concrete or from thin layers of metal. 3) Adjacent hollow columns 3 alternately communicate with the first ventilation duct 1 and the second ventilation duct 2 through the middle ventilation duct 6; The second hollow column communicates with the second ventilation duct, the third holl...

Embodiment 2

[0015] Embodiment 2 On the basis of Embodiment 1, the range of fixed spacing is limited to 1 to 3 meters, that is to say, the distance between adjacent hollow columns is in the range of 1 to 3 meters, which can be considered comprehensively according to engineering goals and costs.

Embodiment 3

[0016] Embodiment 3 On the basis of Embodiment 1 or 2, starting from the outer side of the mountain tunnel where the suction fan and blower are installed, the volume of the hollow columns vertically arranged along the length of the tunnel first gradually increases and then gradually decreases.

Abstract

The invention discloses an achievement method of an internal air purifying system of a mountain tunnel. The method comprises the steps of 1) burying a first ventilating pipeline and a second ventilating pipeline below a mountain tunnel channel in the length direction of the tunnel; 2) vertically arranging hollow columns with air openings at every fixed intervals in the middle of the road in the mountain tunnel in the tunnel length direction; 3) sequentially alternatively communicating adjacent hollow columns with the first ventilating channel and the second ventilating pipeline through a central ventilating pipeline; 4) communicating one end of the first ventilating pipeline with an air inlet of a suction ventilator; communicating one end of the second ventilating pipeline with an air outlet of an air blower, wherein the suction ventilator and the air blower are arranged at the same outer side of the mountain tunnel. According to the method, one of the adjacent hollow columns is used for exhausting air, and while another is used for sucking air; the hollow columns are matched to exchange air, and therefore, air in the tunnel can be purified well.

Description

technical field [0001] The invention relates to the technical field of air purification in mountain tunnels, in particular to a method for realizing an air purification system in mountain tunnels. Background technique [0002] In the long mountain tunnels, the driving vehicles will continuously emit harmful exhaust gas and smoke. When the concentration of harmful exhaust gas and smoke exceeds a certain value, it will bring harm to the drivers and passengers, affecting their health and driving safety. Therefore, in order to ensure the hygienic standards of the air environment required for the normal operation of mountain tunnels, ventilation should be carried out in mountain tunnels, and natural ventilation in longer mountain tunnels cannot achieve the purpose of purifying the air quality in mountain tunnels. Contents of the invention [0003] The technical problem to be solved by the invention is to discharge the waste gas accumulated in the mountain tunnel, so as to ensur...
