Embodiment 1

[0013] Example 1 The mountain tunnel structure with air exhaust and blowing combined to purify air includes rock mass and tunnel lining supporting the rock mass. The tunnel lining constitutes the tunnel body, and also includes blast duct 3, first suction duct 1, The second suction duct 2, the suction fan 5 and the blower 6; the blast duct 3, the first suction duct 1 and the second suction duct 2 can all be made of thin-layer metal; the blast duct 3 is along the length of the tunnel The direction is set on the top of the tunnel body, the first suction duct 1 and the second suction duct 2 are square, the first suction duct 1 is vertically arranged on one side of the tunnel body along the tunnel length, the second suction duct The pipeline 2 is vertically arranged on the other side of the tunnel body along the length direction of the tunnel. On the sides of the blast duct 3, the first suction duct 1 and the second suction duct 2, which are opposite to the tunnel body, there are T...

Embodiment 2

[0014] Embodiment 2 In order to achieve a better purification effect, on the basis of Embodiment 1 or 2, preferably, from the outer side of the tunnel where the suction fan 5 and the blower 6 are provided, along the tunnel length direction, in the blast duct 3. The number of ventilation hole groups 7 on the side of the first air suction duct 1 and the second air suction duct 2 that is opposite to the tunnel body first increases and then decreases.

Embodiment 3

[0015] Embodiment 3 Considering the application in actual engineering, on the basis of Embodiment 3, it is preferred that the position area separated from the outer side of the tunnel with the suction fan 5 and the blower 6 is about two-thirds of the total length of the tunnel Inside, the ventilation hole group 7 hole number on the side opposite to the tunnel body on the side of the blast duct 3, the first suction duct 1 and the second suction duct 2 is the largest. It should be emphasized that about two-thirds of the length of the tunnel is not a definite single distance, but a range of distances, as long as the overall purification ability of the purification device to purify the air in the tunnel can be achieved in the remote tunnel area in the middle. .

Abstract

The invention discloses a mountain tunnel structure that cooperates with air exhaust and blowing to purify air, which comprises a blowing duct, a first suction duct, a second suction duct, a suction fan and a blower; The direction is set on the top of the tunnel body, the first suction duct is set on one side of the tunnel body along the length direction of the tunnel, the second suction duct is set on the other side of the tunnel body along the length direction of the tunnel, and the blowing duct 1. The sides of the first suction duct and the second suction duct opposite to the tunnel body are provided with ventilation holes in groups, and the ventilation holes in the ventilation hole groups are arranged in a matrix. The distance between the ventilation hole groups is equal, and the suction fan The air inlet is connected with one end of the first suction pipe and the second suction pipe at the same time, and the air outlet of the blower is connected with one end of the blower pipe, and the suction fan and the blower are arranged on the same side outside the mountain tunnel, and can be discharged into the mountain tunnel. The accumulated exhaust gas is used to ensure that the air environment in the tunnel meets the standard.

Description

technical field [0001] The invention relates to the technical field of tunnels, in particular to a mountain tunnel structure in which exhaust and blowing cooperate to purify air. Background technique [0002] In the long mountain tunnels, the driving vehicles will continuously emit harmful exhaust gas and smoke, including major pollutants such as carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NOX), because CO is combined with human hemoglobin , directly reduce the amount of oxygen in the blood, causing headaches, drowsiness, and a sense of loss of balance. When the concentration is too high, it will cause death; HC can cause teratogenic, carcinogenic, mutagenic, and cause photochemical smog; NOX can damage the visual and respiratory systems. , causing suffocation, acid rain, and photochemical smog. When the concentration of harmful exhaust gas and soot discharged exceeds a certain value, it will bring harm to drivers and passengers, affecting their health and ...
