Abstract
The invention provides a plasma waste gas refining equipment with no back pressure of motor, low consume dynamic, no catalyst and long service life, which includes exhaust passage with the waste gas import and the gas vent, as well as the high frequency ion generator which establishes on the exhaust passage, its characteristic lies in: the high frequency beam generator has establishes between gas vent and the high frequency ion generator, and forms the granule reaction chamber between the high frequency beam generator and the high frequency ion generator. The equipmentcan be widely used in the gas purifications of locomotive engine exhaust (diesel oil, gasoline), the aquatic motor boat engine exhaust processing (ocean carriage wheel, ocean fishing ship), the thermoelectricity generation chimney dust, factory chimney dust noxious and so on emissions.
Description
Technical field
The present invention relates to exhaust gas treatment technology, particularly a kind of cleaning plant for waste gas of plasma, this device is suitable for the purification of the pernicious gas of dischargings such as locomotive (diesel oil, gasoline) motor exhaust, power ship engine waterborne (transport by sea opinion, long range fishing ship) vent gas treatment, thermal power generation chimney dust, factory chimney dust.
Background technology
The major pollutants of vehicle exhaust comprise carbon monoxide, hydrocarbon and oxynitrides.Carbon monoxide can hinder the blood absorption and the oxygen of human body to be carried, and influences the human body hematopoietic function, may bring out diseases such as angina pectoris, coronary heart disease at any time.Hydrocarbon can form the very strong photochemical fog of toxicity, the injury human body, and can produce carcinogen.The white smoke that produces all has damage to domestic animal, fruit and rubber and building.It is also stronger than carbon monoxide that oxynitrides is poisoned the people, and it damages people's eyes and lung, and form photochemical fog, is the main matter that produces acid rain, can make plant become brown until large tracts of land death by green.
Administer vehicle exhaust and mainly contain three approach.The first, also be basic and the most final approach, change the power of automobile.As develop electric automobile and substitute fuel automobile.This approach does not produce automobile or only produces seldom dusty gas.The second, improve existing automotive powerplant and fuel oil quality.Adopt excellent in design engine, improve chamber structure, adopt new material, improve fuel oil quality etc. automobile gas emission pollution is reduced, but can not reach " zero-emission ".The 3rd, also be being applicable to of extensively adopting at present in a large number at purification techniques with car and new car.Be that the waste gas that adopts some advanced external purification technology that automobile is produced purifies to reduce pollution, this approach can not reach " zero pollutes ".The external purification technology is exactly that various purifiers are installed in the gas extraction system of automobile, adopts the pollutant in method minimizing exhaust physics, chemistry.Can be divided into two classes such as catalyst converter, thermal reactor and filtration gatherer.The former is used for gasoline automobile more, and the latter is used for diesel engine automobile more.
China large-and-medium size cities, motor vehicle exhaust emission have become the main source of atmospheric pollution.Have data to show, the total vehicle in Shanghai City only is equivalent to 1/12 of Tokyo, but mainly basic identical by the total amount of CO, the HC of motor vehicle emission and NOx in the air.At present China's vehicle in use amount has more than 1,300 ten thousand, yet along with the increase of rapid economic development and society need, in 10～15 years from now on, the Chinese automobile recoverable amount will be with average annual 9% speed increment.This shows, reduce the urgency of motor vehicle exhaust emission thing.
Developed countries such as Europe, the U.S. and Japan are early also strict to motor vehicle exhaust emission control, and therefore, their used cleaning catalyst for tail gases of automobiles is more extensive.Mainly be three-way catalyst at present.This catalyst promptly makes HC and CO be oxidized to H
2O and CO
2Oxidant, also make NOx be reduced into N
2Reducing agent.So just can play good catharsis.Can not get the effect that this has and this method enters Chinese market because of the qualitative factor of vehicle condition and fuel oil, almost fail.
The inventor thinks that the technology of utilizing the particle effect principle to handle tail gas might be global breakthrough, also is the inevitable trend of technical development from now on.
Summary of the invention
The present invention is directed to the defective or the deficiency that exist in the prior art, providing a kind of does not have back pressure to engine, and consumption of power is low, need not to add catalyst, the cleaning plant for waste gas of plasma of long service life.This device can be widely used in the purification of the pernicious gas of dischargings such as suitable locomotive (diesel oil, gasoline) motor exhaust, power ship engine waterborne (transport by sea wheel, long range fishing ship) vent gas treatment, thermal power generation chimney dust, factory chimney dust.
The technical conceive of the innovation invention is to utilize the enough positive and negative charge numbers of low temperature plasma mesopodium to be bordering on equal charged particle the NOx in the waste gas is reduced into N
2And O
2, and pass through the rays excite particle that the high-frequency ray transmitter produces, nuisance is decomposed the purpose that reaches Purge gas thereby under interacting, produce particles conversion phenomenons such as new particle or generation particle decay.
