Automobile tail gas purifier of low-temperature plasma body

Abstract

The invention discloses a low temperature plasma purification device for automobile exhaust, which comprises a high frequency power supply, a power amplifier, an adapter, a controller and a discharge cavity. The high frequency power supply generates high frequency oscillatory signals from 10KHz to 100KHz. The high frequency oscillatory signals pass through the power amplifier to enlarge power thereof, then is sent to the adapter so as to generate multi-channel high-voltage signals before being sent to the discharge cavity to generate the low temperature plasma; the discharge cavity is arranged inside an exhaust pipe of an automobile. Since the low temperature plasma purification device for automobile exhaust of the invention adopts the low temperature plasma to process hazard substances such as particulate matters, sulfur dioxide, nitrogen oxides, etc. in the automobile exhaust, and introduces advanced power technology, harmful gas removing rate of the invention is not easily influenced by air fuel ratio and the change of working state of engines compared with the traditional automobile exhaust processing technology of three-way catalytic conversion, thus having long service life and low cost.

Description

technical field [0001] The invention relates to a vehicle tail gas purification device, in particular to a tail gas treatment device which adopts low-temperature plasma to purify the car tail gas, which can be used for general car tail gas treatment to reduce harmful gas emissions from the car. Background technique [0002] Automobile is a symbol of modern industrial civilization, and its vigorous rise is only a history of more than 100 years. After the end of the Second World War, the number of cars increased day by day. By the end of 2000, the number of cars in the world had exceeded 600 million. The number of automobiles in China reached 33.56 million in 2005 and will reach 131.03 million in 2020. Exhaust gas emitted by automobiles has become one of the main sources of air pollution in many large cities in the world. [0003] At present, the health of more than 1 billion urban populations in the world is threatened by air pollution caused by vehicle exhaust. China's au...
