FIG. 2 is a view for explaining the flow of soot according to FIG. 1, FIG. 7 is a view showing a state of use of a ventilation system for a tunnel capable of removing black carbon of a soot according to an embodiment of the present invention. FIG.

As shown in the drawings, the ventilation system for a tunnel capable of removing the black carbon of the soot according to an embodiment of the present invention includes the ventilator 100, the water spraying unit 200, and the water recovery unit 300 .

The ventilator 100 serves to discharge the air inside the tunnel to the outside. In an embodiment of the present invention, the ventilator 100 is installed on the ceiling of the tunnel, and a plurality of ventilators may be provided.

The water injector 200 injects water into the soot discharged through the ventilator 100 to separate the black carbon from the soot. It is preferable that the water jetting unit 200 injects water in the form of a spray. On the other hand, in the present invention, water is used to separate black carbon contained in soot, but the separation medium is not limited thereto.

The water recovery unit 300 is provided below the fan 100 so that the sprayed water in which the black carbon is melted does not fall to the lower road side.

Therefore, according to one embodiment of the present invention, when the soot in the tunnel is discharged to the outside, the black carbon included in the soot is filtered and discharged to the outside, thereby preventing environmental pollution in advance.

Hereinafter, the operation of a ventilation system for a tunnel capable of black carbon removal of soot according to an embodiment of the present invention will be described.

As shown in Fig. 3, it is preferable that the present invention is installed in a tunnel. But the present invention is not limited thereto.

Accordingly, the soot generated as the vehicle passes through the tunnel is discharged to the outside through the ventilator 100.

At this time, the water spray part 200 injects water into the soot discharged through the ventilator 100 so that the black carbon contained in the soot discharged through the ventilator 100 can be removed.

Then, the black carbon is dissolved in the water and falls into the water recovery part 300 like water, and the soot from which the black carbon is removed is discharged to the outside through the ventilator 100.

4 is a functional block diagram of a ventilation system for a tunnel capable of black carbon removal of soot according to another embodiment of the present invention. As shown in FIG. 4, according to another embodiment of the present invention, a filter unit 600 is further included.

In the other embodiments of the present invention, since the configuration of one embodiment is all included, a detailed description thereof will be omitted.

The filter unit 600 filters the black carbon in the water recovered through the carbon recovery unit 700 to separate the black carbon from the water, and the black carbon supplies the filtered water to the water spray unit 200 .

As described above, the filter unit 600 is further included in the embodiment of the present invention, so that the black carbon is filtered and separated from the water containing black carbon, 200 to circulate the water.

The black carbon may be connected to the filter unit 600 and may include a carbon recovery unit 700 to store the filtered black carbon. Thus, when the carbon recovery unit 700 is provided, there is an advantage that the pollutant such as carbon can be easily treated.
