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 setting method for automatically purifying the air in a long tunnel, 1) Buried the first ventilation duct 1 and the second ventilation duct 2 along the length of the tunnel under the road in the 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) Hollow columns 3 with air outlets are erected at intervals along the length of the tunnel on the road in the tunnel. The hollow columns 3 are preferably erected in the middle of the road in the tunnel to facilitate the passage of vehicles. The hollow columns can be poured with concrete It can also be made of 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 hollow column communicate...

Embodiment 2

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

Embodiment 3

[0016] Embodiment 3 On the basis of Embodiment 1 or 2, the blower and the suction fan are arranged on the same side outside the tunnel, and from the outside side of the tunnel where the suction fan and blower are installed to the other side, the volume of the hollow column first gradually increases and then gradually increases. Reduced, and the hollow column with the largest volume is about one third of the tunnel length from the other side of the tunnel.

Abstract

The invention discloses a setting method for automatically purifying air in a long tunnel. The setting method for automatically purifying the air in the long tunnel comprises the following steps that 1, a first ventilated duct and a second ventilated duct are embedded under a road in the tunnel in the longitudinal direction of the tunnel; 2, hollow columns with air ports are vertically arranged at intervals on the road in the tunnel in the longitudinal direction of the tunnel; 3, adjacent hollow columns are sequentially and alternatively connected with the first ventilated duct and the second ventilated duct through middle ventilated ducts; 4, one end of the first ventilated duct is communicated with an air inlet of a suction fan, one end of the second ventilated duct is communicated with an air outlet of an air blower, and the suction fan and the air blower are arranged outside the tunnel; 5, an air quality test module is arranged on the middle area of the tunnel, and the air quality test module transmits air quality test data to a miniature control unit; 6, the miniature control unit controls the opening and closure of a driving circuit of the suction fan and the air blower. According to the setting method for automatically purifying the air in the long tunnel, one hollow column is used for air exhaust and the other hollow column is used for air suction in the adjacent hollow columns, and therefore changing air is finished in cooperation, and automatically purifying the air in the tunnel is achieved.

Description

technical field [0001] The invention relates to the technical field of air purification in mountain tunnels, in particular to a setting method for automatically purifying air in long 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 long tunnel, so as to ensure that t...
