Detailed Description

The utility model is further illustrated below with reference to specific examples and experimental data. It is to be understood that the embodiments of the present invention are merely for illustrating the present invention and not for limiting the present invention, and that various substitutions and alterations made according to the common knowledge and conventional means in the art without departing from the technical idea of the present invention are included in the scope of the present invention.

Example (b):

as shown in fig. 1-4, a tunnel ventilation structure, including locate ventilation air flue 1 in the tunnel and set up fan 2 in the ventilation air flue 1, ventilation air flue 1 sets up in tunnel one side at least, ventilation air flue 1 includes waste gas import 11 and new trend export 12, fan 2 locates waste gas import 11 with between the new trend export 12, fan 2's blade pivot 22 is connected with the main shaft 31 of first motor 3, waste gas import 11 is equipped with external impurity absorption cover 111, new trend export 12 department is equipped with air outlet fan 4. According to the utility model, the ventilation air channel 1 is arranged at least on one side of the tunnel, so that the exhaust gas in the tunnel is sucked from the exhaust gas inlet 11, and fresh air is supplemented to the tunnel from the fresh air outlet 12 after the exhaust gas is treated by air, and effective air circulation in the tunnel is established. Wherein, the air treatment is carried out the air purification treatment by a fan 2 arranged in the middle of the ventilation air passage 1 and a plurality of rows of filtering structures and ozone generators 6.

Further, the ventilation air passages 1 can be arranged on two sides of the tunnel.
