Non-exhaust fine dust collecting device using triboelectricity

1. A non-exhaust fine dust collecting apparatus using frictional electricity, comprising;

an air pipe mounted in a vehicle and provided with an inlet through which fine dust generated in a vehicle and charged with a first polarity flows together with air; and

a dust collector mounted at a side of an outlet of the air pipe and charged with a second polarity that is opposite to the first polarity to collect the fine dust charged with the first polarity,

wherein

the inlet is formed at a position where a rate of air flow between a wheel and a wheel well slows down and is stagnant.

2. The non-exhaust fine dust collecting apparatus of claim 1 , wherein

the air pipe includes a wheel well of the vehicle and a guide mounted to the wheel well,

the inlet is formed toward the guide to open toward the wheel disposed inside the wheel well, and

the outlet opens toward a rear side of the wheel.

3. The non-exhaust fine dust collecting apparatus of claim 1 , wherein

the inlet includes

a first inlet configured to open downward to face a first stagnation point that is formed vertically above a central axis of the wheel, and

a second inlet configured to open forward to face a second stagnation point that is formed at a horizontal rear side from the central axis of the wheel.

4. The non-exhaust fine dust collecting apparatus of claim 3 , wherein

the outlet includes

a first exit formed as a vertical gap between a lower end of the guide and a lower end of the wheel well at a rear side of the guide, to open a rear side thereof, and

a second exit formed as a horizontal gap between the first exit and the dust collector at a rear side of the first exit, to open a rear side thereof.

5. The non-exhaust fine dust collecting apparatus of claim 4 , wherein

the dust collector is spaced rearward from the first exit to form the second exit, and is installed in a side sill or a rear body of the vehicle.

6. The non-exhaust fine dust collecting apparatus of claim 1 , wherein

the fine dust is charged with the first polarity caused by friction between a tire on asphalt and the wheel or between a brake pad and a disk pad.

7. The non-exhaust fine dust collecting apparatus of claim 1 , wherein

the dust collector includes

a duct configured to pass a flow of the fine dust,

a plurality of charging plates installed inside the duct to be charged with the second polarity by applying a charging voltage, and

a plurality of filters respectively installed on the plurality of charging plates to collect fine dust.

8. A non-exhaust fine dust collecting apparatus using frictional electricity, comprising;

an air pipe mounted in a vehicle and provided with an inlet through which fine dust generated in a vehicle and charged with a first polarity flows together with air; and

a dust collector mounted at a side of an outlet of the air pipe and charged with a second polarity that is opposite to the first polarity to collect the fine dust charged with the first polarity,

wherein

the air pipe further includes a venturi inside the inlet.

9. The non-exhaust fine dust collecting apparatus of claim 8 , wherein

the air pipe further includes a micropath at opposite sides of the inlet, and

the micropath allows air to flow from outside of the inlet to a recess portion of a venturi disposed inside the air pipe.

10. A non-exhaust fine dust collecting apparatus using frictional electricity, comprising;

an air pipe mounted in a vehicle and provided with an inlet through which fine dust generated in a vehicle and charged with a first polarity flows together with air; and

a dust collector mounted at a side of an outlet of the air pipe and charged with a second polarity that is opposite to the first polarity to collect the fine dust charged with the first polarity,

wherein

the air pipe and the inlet are installed by analyzing a streamline of an air flow formed between a wheel and a wheel well of the vehicle, and

wherein

the inlet is disposed at a stagnation point where a rate of the air flow is slow and it is stagnant by allowing a movement of the wheel rotating in a first direction to act on the air flow flowing in an opposite direction to the first direction.
