1 to 4, the vehicle fine dust removal apparatus 10 according to an embodiment of the present invention includes a body 100, a settling portion 200 and a multi-stage purification unit 300.

The main body 100 is mounted under the rear of the vehicle to form a space in which exhaust gas discharged from the exhaust port of the vehicle can be accommodated. In addition, an inlet 110 and an outlet 120 are provided so that the exhaust gas discharged through the exhaust port is introduced into the body 100 to be purified and discharged to the outside.

The main body 100 is formed in a rectangular enclosure, and has a sedimentation unit 200 and a multi-stage purification unit 300 therein to remove fine dust from exhaust gas of a vehicle.

The settling part 200 removes fine dust by contacting the exhaust gas introduced through the inlet 110 with purified water. In more detail, the settling unit 200 includes a water tank 210 in which purified water is accommodated and a distribution inlet 220 for distributing and injecting exhaust gas into the water tank 210.

The distribution inlet 220 is formed in plural to distribute exhaust gas discharged from the vehicle. The distribution inlet 220 makes several small holes as shown in FIG. 2 to disperse the exhaust gas and injects it into the purified water of the water tank 210. At this time, the lower surface of the distribution inlet 220 is in a state in which the water surface is in contact, and since the distribution inlet 220 is formed as a small hole, an exhaust gas column can be formed into the purified water of the water tank 210 by the output of the exhaust gas. In this case, the exhaust gas can penetrate deep into the purified water.

That is, the distribution inlet 220 is formed as a small hole and serves to increase the exhaust gas discharge pressure.

In addition, a water collecting part 222 for collecting purified water overflowing from the water tank 210 is formed in the distribution inlet 220. The water collecting part 222 is formed in a jar shape that is recessed in a semicircular shape, so that the purified water in the water tank 210 can be collected when the vehicle shakes, and when the purified water enters the water collecting part 222, the exhaust gas is mixed and purified. Can be started.

The water tank 210 is formed with a loading part 212 in which the precipitated contaminants are loaded. The loading part 212 is formed on the center of the bottom surface of the water tank 210, that is, in the width direction of the main body 100 perpendicular to the longitudinal direction of the vehicle.

In addition, the bottom surface of the water tank 210 is formed to be inclined downward in the direction of the loading portion 212, and a cleaning tool 214 capable of opening and closing is formed in the loading portion 212. In addition, as shown in FIG. 3, the loading part 212 is formed to be inclined downward toward the cleaning tool 214. This is a structure for easy discharge of pollutants by opening the water outlet.

On the other hand, a water supply cock 130 for supplying purified water to the water tank 210 is formed on one side of the main body 100.

The multi-stage purification unit 300 is provided between the sedimentation unit 200 and the outlet 120 to filter the exhaust gas passing through the sedimentation unit 200 in multiple stages, so that fine dust from the exhaust gas introduced from the sedimentation chamber is settled down. The seating chamber 310 and the seating chamber 310 are respectively disposed before and after the filter member 320 to filter exhaust gas.

The seating room 310 forms a certain area so that the exhaust gas introduced from the settling part 200 is settled on the bottom surface. The sitting room 310 is provided above the water tank 210 so that the main body 100 may have a compact structure.

In addition, in the sitting room 310, a sitting plate 312 is formed in parallel with the floor so that the exhaust gas sits on the floor.

The filter member 320 is provided between the sedimentation unit 200 and the seating chamber 310, and is provided between the wet filter 322 containing purified water of the sedimentation unit 200 and the seating chamber 310 and the outlet 120 It consists of a dry filter 324 to filter the exhaust gas.

The wet filter 322 is provided in the passage between the sedimentation part 200 and the sitting room 310, is formed in a sponge shape, and is partially contained in the water tank 210, so that the purified water is contained by the osmotic pressure action. Accordingly, the exhaust gas may be filtered by the wet filter 322 and moved to the seating room 310.

In addition, the wet filter 322 may fluctuate due to various factors such as movement, stop, and slope of the vehicle. In this case, the purified water of the water tank 210 is prevented from flowing into the sitting room 310.

In addition, a part of the wet filter 322 is cut and removed to form a buffer space 323 between the settling part 200 and the seating chamber 310. This is because when the amount of air bubbles increases due to the increase in exhaust gas at the distribution inlet 220, the water level of the water tank 210 increases, which can be accommodated.

The dry filter 324 may be made of a fibrous material such as cloth or a sponge, and is supported by a frame to maintain its shape.

The dry filter 324 finally filters fine dust that is not filtered by the sediment 200, the wet filter 322, and the sitting room 310 before discharging.

Hereinafter, the operation and effect of the vehicle fine dust removal apparatus 10 according to an embodiment of the present invention will be described.

Referring to FIG. 4, the exhaust gas discharged through the exhaust port of the vehicle is introduced into the interior of the body 100 through the inlet 110, and the introduced exhaust gas is a water tank through the distribution inlet 220. 210) is injected with purified water. When the exhaust gas enters in a bundle type, since a plurality of distribution inlets 220 are formed with small holes, the output is ejected into the purified water of the water tank 210, and can be transmitted to a deeper place, so that the contact between the exhaust gas and the purified water is possible. It is enlarged, and the precipitation efficiency of fine dust can be improved.

At this time, when the water level is raised by injection of the exhaust gas, the increased water level is accommodated in the buffer space 323. Air bubbles generated by the injection of exhaust gas are moved toward the buffer space 323, and wet filtering is performed by the wet filter 322. At this time, the wet filter 322 may prevent the purified water from the water tank 210 from flowing into the sitting room 310. In addition, fine dust filtered by the wet filter 322 due to the sloshing of the vehicle may be washed and precipitated in purified water.

In addition, since the exhaust gas is brought into contact with the purified water in the water tank 210, the heat contained in the exhaust gas is also changed to low heat, so that the exhaust gas can be filtered while the heat is removed.

Thereafter, the exhaust gas passing through the wet filter 322 is introduced into the sitting room 310 and is seated. As seen from the flow path of the exhaust gas, the seating room 310 has a larger spatial area to reduce air flow, so that fine dust contained in the exhaust gas settles on the floor of the seating room 310. At this time, the sitting room 310 is provided with a sitting plate 312 that is parallel to the bottom surface of the sitting room 310 so that fine dust of the exhaust gas is spread on the floor, thereby increasing the sitting effect.

The exhaust gas passing through the sitting room 310 is finally discharged to the outside through the outlet 120 through the dry filter 324.

As described above, according to the device for removing fine dust for a vehicle according to an embodiment of the present invention, the exhaust gas discharged from the vehicle is brought into contact with purified water to precipitate foreign substances, and by filtering in multiple stages, the fine dust discharged from the vehicle is suppressed. And there is an effect that can be removed, even heat to be discharged into the air by removing.

In addition, since it can be manufactured without expensive filters due to its structural features, it can be supplied at low cost, and it can be applied to not only automobiles manufactured in the future, but also existing automobiles in actual operation, so that popularization is easy.
