Abstract
A non-exhaust fine dust collecting apparatus using friction electricity is disclosed. An exemplary embodiment of the present invention provides a non-exhaust fine dust collecting apparatus using friction electricity, including: 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.
Claims10
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.
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.
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.
