3 and 4, an apparatus 200 for adsorbing and removing an air pollutant according to a third embodiment of the present invention will be described. The same reference numerals are given to the same parts as those described in the first and second embodiments, and a detailed description thereof will be omitted.

4 and 5, the apparatus 200 for adsorbing and removing air pollutants according to the third embodiment of the present invention includes a suction unit 210 for sucking outside air, a suction unit 210 for sucking air, A duct 130 through which the air that has passed through the filtering unit 220 flows, and a duct 130 that receives a person or is operated by a person directly or through an automobile A jetting part 140 installed in the upper structure 90 covering the upper part of the space 92 and spraying the air having passed through the duct 130 downward to block the introduction of the outside air into the space 92 .

Here, the suction unit 210 may be integrally formed with the filtering unit 220 in one housing 223.

The suction unit 210 may include a flow fan 211 disposed in the housing and a fan motor 212 connected to the flow fan 211 to rotate the flow fan 211. As the flow fan 211, a fan having various shapes such as an axial flow fan or a cross flow fan can be used. The fan motor 212 may be a general rotary motor.

The filtering unit 220 is a wet filter for removing contaminants by using a liquid. The filtering unit 220 includes a housing 223 in which a liquid is accommodated, a housing 223 rotatable about a horizontal axis 243 in the housing 223, And a dust collecting member 240 installed to partially submerged in the liquid contained in the dust collecting member 223.

An inlet 221 through which air flows is formed in the upper portion of the housing 223. A flow fan 211 of the suction unit 210 is disposed between the inlet 221 and the dust collecting member 240. Around the flow fan 211 in the housing 223, a discharge port 222 through which air is discharged is formed. External air is sucked into the inlet 221 by the operation of the flow fan 211 and flows toward the dust collecting member 240. The air is discharged to the discharge port 222 after colliding with the dust collecting member 240. [

However, the present invention is not limited to this, and the dust collecting member 240 may be rotated by the force of the air sucked by the flow fan 211 of the suction unit 210. A plurality of vanes 242 may be provided around the dust collecting member 240 to collide with the air so that the dust collecting member 240 can be smoothly rotated by the sucked air.

The external air is sucked from the inlet 221 formed on the upper side of the housing 223 by the operation of the flow fan 211 and collides with the dust collecting member 240. [

At this time, the contaminants contained in the outside air are adsorbed on the dust collecting member 240 while colliding with the dust collecting member 240 being rotated. At this time, the contaminants may be adsorbed between the dust collecting grooves 241 of the dust collecting member 240. The air having the pollutant removed by the dust collecting member 240 is discharged to the discharge port 222 and flows in the duct 130 along the guide duct 250. Thereafter, And is discharged to the outside through the scraper 140.

Meanwhile, the contaminants adsorbed on the dust collecting member 240 are separated from the dust collecting member 240 while moving in the water or the cleaning liquid by the rotation of the dust collecting member 240.

The apparatus for adsorbing and removing air pollutants according to the third embodiment of the present invention configured as described above is characterized in that an air blocking film for blocking the space 92 in the structure 9 from the outside is formed, It is possible to prevent the inflow of the air containing pollutants. Therefore, it is possible to prevent a person in the space 92 from coming into contact with the pollutant.

Particularly, when the inside of the space 92 of the structure 9 is cooling or heating, the cooling loss or the heating loss is prevented from occurring due to heat exchange with the outside air, and the inside of the space can be maintained at a constant temperature.

In addition, the apparatus for adsorbing and removing air pollutants according to the third embodiment of the present invention can filter the contaminants contained in the air by using the dust collecting member 240, which is partially received and rotated in the water or the washing liquid, Thereby providing cleaner air.

Meanwhile, the apparatus for adsorbing and removing air pollutants according to the embodiments of the present invention can be variously configured such as a structure itself such as a bus stop, a tollgate or a settling booth installed in a parking lot, or the like, or installed in a tunnel or the like.

In particular, the filtration unit 120 and the jetting unit 140 can be variously modified in accordance with the structure and the installation position thereof, in addition to those shown in Figs.

By way of example, the apparatus for adsorbing and removing air pollutants according to the present invention may be installed on the ceiling of a structure 9 such as a tunnel, as shown in FIG.

At this time, a support portion 129 for supporting the filtration portion 120 and the jetting portion 140 is installed on the ceiling of the structure 9.

The jetting unit 140 is directly connected to the filtration unit 120, and can be jetted toward a vehicle, a person, or the like, which is sucked by the filtration unit 120 to remove pollutants, downwardly.

As another example, the apparatus for adsorbing and removing air pollutants according to the present invention may be installed on the edge side of a road inside a structure 9 such as a tunnel, as shown in Fig.

The inlet of the filtration unit 120 is directed toward the road and the filtration unit 120 sucks air on the road side including soot discharged by a vehicle or the like to remove contaminants, The air having the pollutants removed by the air blower 120 can be jetted toward the vehicle, the person, etc. by the jetting unit 140 via the guide unit 130.
