System for purifying air in tunnel

Abstract

The invention discloses a system for purifying air in a tunnel. The system comprises a dust-collecting filter pipe (1), and is characterized in that the dust-collecting filter pipe (1) is connected with a sterilizing chamber (2); the sterilizing chamber (2) is connected with a ventilation fan (3); the ventilation fan (3) is connected with an air liquid mixing tank (5); the air liquid mixing tank (5) is connected with an air curtain dust collector (10). The system can solve the technical problems of the prior art that the purifying effect of an air purifying device in the tunnel is poor, the air purifying device is difficult to move, the treating air volume of the matched dust collector is large, the weight and the volume thereof are both large, the movement is difficult and the movement and arrangement of the matched devices often cannot be timely implemented, so that the dust-reducing effect of the tunneling work surface is reduced, the exerting of the driving machinery effect is influenced, and the like.

Description

technical field [0001] The invention belongs to the air purification technology, in particular to a system for purifying the air in a tunnel. Background technique [0002] With the increasing level of tunnel mechanization, the amount of flour dust produced by tunnel excavation is increasing. In the mechanized excavation face of the tunnel, the dust concentration is high, which not only brings unsafe hidden dangers to the tunnel, easily causes safety problems, but also seriously damages the health of workers and causes pneumoconiosis among employees. In order to solve the problem of the outward diffusion of mechanized flour dust, in recent years, dust removal measures such as ventilation and dust removal, wet operation, and air purification have been adopted in China. However, due to the frequent movement of the dust source, the high-speed press-in air flow carries a large amount of dust from the working surface and spreads outward, so that most of the dust-laden air flow ca...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a system for purifying the air in the tunnel, so as to solve the problem that the air purification device in the tunnel in the prior art has poor purification effect and is difficult to move, and the matching dust collector has a large air volume, and its weight and volume are large , moving is also difficult, often because the relocation of supporting equipment cannot keep up with it in time, thus reducing the dust suppression effect of the excavation face and affecting the performance of excavation machinery and other technical problems
