Although not shown, the communication part 800 is provided with a separate shutoff cover (not shown) for selectively closing the communication part 800, and can be selectively opened and closed according to the direction and position in which the cells are coupled.

Therefore, when the cells are coupled to each other, the blocking cover is opened. When the cells are not coupled to each other, the blocking cover can close the communication part 800, thereby preventing the uncleaned air from being discharged.

In this manner, the inflow part cell and the discharge part cell are provided with the blowing part 400 to circulate the introduced air so that air is delivered to the other cells.

The purge section 500 is provided in the communication part 800 to guide the air sucked into the inlet part 100 through the duct into the flow path cell coupled with the inlet part cell, It is possible to purify contaminated air.

At least two or more of the cells may be selectively coupled to each other according to the length of the tunnel.

The cells may be bonded to each other or may be bonded to each other.

Specifically, one inlet cell 100 and five flow cell 300 cells may be combined to be long in the longitudinal direction of the tunnel T.

A plurality of cells may be arranged along the longitudinal direction of the tunnel T in correspondence with the number of cells of the flow path portion 300. In this case,

Therefore, each of the cells may be provided with a coupling portion (not shown) so as to be able to be coupled with another cell.

The coupling portion is provided at a portion to which each cell is coupled, the protrusion is provided on one surface of the case (C), and the depression groove is provided on the other surface of the case (C).

In addition, it can be embedded in the inner side or inside of the tunnel lining in the form of such a cell.

The manner in which the coupling portion is coupled is not limited to the interference fit type but can be variously cited such as chain connection or bolt coupling. Accordingly, the scope of the right is not limited.

In this case, the number and arrangement order of each cell can be changed according to the characteristics and the length of the tunnel T, and it is possible to design easily by those skilled in the art.

Will be described in detail with reference to the drawings.

As shown in the figure, each cell is disposed along the longitudinal direction of the tunnel T.

The inlet cell is coupled to the channel 300, and the next cell is connected.

At the side of the convection cell, a flow cell is again provided, followed by a discharge cell.

In addition, the coupling part is provided with a communication part 800 so that air flows between them.

The purge section 500 is provided inside the channel section 300 to form a water film for purifying the air inside the tunnel T to remove contaminants.

Depending on the shape of the cell, the water supply pipe 520 may be long along the longitudinal direction of the tunnel T, and the water supply pipe 520 and the injection nozzle 510 of each channel unit 300 cell may be connected to each other .

Accordingly, in the present embodiment, one air purifier 10 may be provided depending on the length of the tunnel T, and a plurality of air purifiers 10 may be provided intermittently, May be adjusted.

Each configuration of the air purifier 10 may have the same configuration as that shown in Fig.

As shown, the flow path portion 300 can be separated into at least two portions.

9, a plurality of flow paths 300 are repeatedly provided in the vertical direction of the tunnel T, and the flow paths 300 are separated into at least two independent cells, .

The inflow part 100 and the discharge part 200 are provided with a purifying filter 320 in a part communicating with the flow path part 300 to have a shape of a cell.

The characteristics of each cell can be specifically segmented and combined in various forms corresponding to the length and shape of the tunnel T. [

Accordingly, the separated cells are provided to communicate with each other when the cells are coupled, and can be coupled if the channel portion 300 is in communication even if the cells are inverted up or down according to circumstances.

Unlike the illustrated embodiment, if the inlet 100, the outlet 200, and the flow passage 300 can communicate with each other, the separation width of each cell of the air purifier 10 can be variously changed.

In this way, the shape of the cell can be arranged or buried in the tunnel T according to the form and situation of the tunnel T.

A plurality of pipes can be freely arranged and connected to each other in accordance with the length of the tunnel T so that the purifier 500 capable of purifying the inflow air can be arranged long to purify the air have.

11 is a perspective view showing an appearance of the air purifier 10 provided inside the case C. As shown in Fig.

As shown in the figure, each cell is provided to be able to engage and is buried in the side of the tunnel T to purify the air inside the tunnel T.

On the other hand, since the air purifier 10 of the present invention is operated for a long time, it is preferable that the air purifier 10 is mounted or embedded on the side of the tunnel lining to facilitate maintenance when a failure occurs.

12 is a view showing a state in which an air purification apparatus 10 is buried in a tunnel lining and maintenance is performed in a tunnel-embedded type air purification apparatus 10 according to an embodiment of the present invention.

Since the air purifier 10 of the present invention is operated for a long period of time, maintenance must be smoothly performed.

As shown in the figure, the operator can easily repair the air purifier 10 provided on the side surface in order to repair the air purifier 10 of the present invention.

However, when the air purifier 10 of the present invention is installed in the ceiling of the tunnel T, the operator performs the repair using a separate ladder, which has the disadvantage that the vehicle can be blocked in and out .

However, it is preferable that the inflow part 100 is extended to the upper part of the tunnel T in consideration of the fact that dust or the like is collected on the upper part due to the movement of the automobile.

13 is a view showing a state in which an inflow section 100 is installed on an upper part of a tunnel T in an air purification apparatus 10 of a liquid purification type according to an embodiment of the present invention.

The air purifier 10 of the present invention is mounted or embedded in the side lining of the tunnel T and the inlet 100 is extended to the top of the tunnel T by a separate extension pipe .

This is because the position of the inflow part 100 is adjusted in consideration of the characteristic that the air inside the tunnel T is collected at the upper part according to the movement of the vehicle. The inflow part 100 is disposed at a place where the pollutant is high, It is possible for a person skilled in the art to easily change pollutants in the tunnel T to be collected.

In addition, the inflow unit 100 not only can cool the heat by injecting water through the injection nozzle 510 when the inside of the case C receives a fire when a fire occurs in the tunnel T, Toxic gases and harmful substances generated in the tunnel (T) are also sucked in and the expansion of the fire can be prevented and prevented.

It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. It is obvious to them. Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.
