Abstract

A device for tunnel dedusting, ventilating and purifying on the basis of the smoke concentration comprises a smoke concentration detector and an air outlet pipeline which are arranged on the side wallof a tunnel. A first cable trough is formed in one side inside the tunnel, and a second cable trough is formed in the other side inside the tunnel. Slab culvers are arranged above the first cable trough and the second cable trough correspondingly, and an atomization box body is arranged in the first cable trough. An atomization device is arranged in the atomization box body, and an air suction device for purifying air in the tunnel is arranged in the second cable trough and connected with a transverse drainage pipe in the tunnel. In the operating process of the device, the long-time uninterrupted ventilating effect can be achieved, the current situation that the concentration of particles in the tunnel is large is improved, and the quality of the air in the tunnel is improved; and in theoperating process of the device, generated noise is low, the influence on personnel in the tunnel is reduced, and the driving comfort is improved.

Description

technical field [0001] The invention relates to the technical field of tunnel ventilation, in particular to a device for dust removal, ventilation and purification of tunnels based on smoke concentration. Background technique [0002] The country's requirements for the service level of transportation infrastructure are further improved, and it is bound to vigorously develop underground space projects. As an important control project of transportation infrastructure, tunnels will face the challenge of ventilation during operation. The exhaust gas emitted by cars contains many harmful components, such as carbon monoxide, smoke, nitrogen oxides, lead, sulfur dioxide, phosphides, etc. , is a mixture of gaseous and floating solid particles. The tunnel is a closed space, generally only the entrance and exit are connected to the atmosphere, and pollutants cannot diffuse quickly, so the concentration of polluted air in the tunnel will gradually accumulate. These harmful gases have...
