Description
Technical field
The invention belongs to auto-parts technical field, relate in particular to a kind of vehicle-exhaust exhaust pipe based on Electrostatic Absorption.
Background technique
At present, recoverable amount is soaring rapidly per capita for the automobile of China, and automobile discharges the tail gas not filtering in a large number every day, and automobile exhaust pollution is day by day serious, and a large amount of vehicle exhausts constantly decline urban air-quality, and pollution of atmosphere is worth to be worried.In recent years, urban motor vehicle increases very fast, incident traffic noise pollution environmental phenomenon also becomes increasingly conspicuous, automobile is noise pollution to the harm of environmental protection maximum, investigation shows, motor vehicle noise accounts for 85.5% of urban traffic noise, along with the development of automotive energy-saving emission-reducing, require automobile to reduce noise, energy saving consumption.And the topmost noise of automobile is from the vent systems of automobile, it is motor vehicle exhaust emission noise, in order to reduce motor vehicle exhaust emission noise, meet the requirement of automobile environment-protection, traditional automobile exhaust system is by fixing a silencer to realize noise elimination noise reduction, but acoustic wave filter structure is complicated, and install also inconvenient.
Current social, industrial production is fast-developing, ecotope is seriously damaged, and atmospheric pollution is serious, and particularly living standards of the people improve, private car enters in Common People, owing to being subject to the impact, particularly urban road low running speed of sulfur phosphorus compound in fuel qualities, lubricant oil and day by day serious factors such as traffic congestion, traffic light are more, the oil-fired system of automobile is easy to generate carbon distribution and colloid, and intake manifold has dust grease etc.And principal element of air-polluting is: give off a large amount of harmful gases during automobile uses, although installed ternary catalyzing unit additional, sulfur-bearing in gasoline, phosphorus composition are high, easily form one deck sulphur, phosphorus chemistry complex compound on ternary catalyzing unit surface; City blocks up, gasoline car frequent starting, cause engine combustion insufficient, and burn incompletely product can be attached to the surface of ternary catalyzing unit, cause ternary catalyzing unit function to reduce, nitrogen oxide in exhaust emissions (NO) content overproof, aggravated the pollution of air, emission from vehicles simultaneously exceeds standard, and power declines, the series of problems such as oil consumption increase.
Not only smell is strange to plant gaseous effluent, and makes us dizzy, nauseating, affects the healthy of people.In the situation that vehicle is few, the self cleaning capacity of atmosphere still can be dissolved the toxin that automobile is discharged.But along with the sharply increase of automobile quantity, the traffic congestion normal potluck that gets married, convenient, comfortable, the efficient advantage that automobile should possess is offset by too much vehicle gradually." automobile disaster " forms, and no small harm is done especially for the vehicle exhaust bringing thus.
Scientific analysis shows, contains hundreds of different compound in vehicle exhaust, and pollutant wherein has Solid Suspension particulate, carbon monoxide, carbon dioxide, hydrocarbon, oxynitrides, lead and oxygen sulfur compound etc.Large 3 times than own wt of the harmful exhausts of car discharge in a year.Britain's air cleaning and environmental protection association once delivered research report and claimed, victim compares with traffic accident, and Britain dies from air-polluting people every year will have more 10 times.
Harmful matter
Solid suspended particle: the composition of solid suspended particle is very complicated, and there is stronger adsorptive power, can adsorb various metallic dusts, strong carcinogen BaP and pathogenic microorganism etc.Solid suspended particle enters human lung with breathing, colliding, to spread, the mode such as deposition is trapped in the different parts of respiratory tract, causes respiratory disease.When suspended particulate runs up to critical concentration, just may excite formation malignant tumour.In addition, suspending particulate matter can also directly contact skin and eyes, blocks hair follicle and the sweat gland of skin, causes dermatitis and eye conjunctivitis, even also may cause corneal injury.
Carbon monoxide: fast 250 times than oxygen of the speed that the hemoglobin of carbon monoxide in blood is combined.Carbon monoxide enters blood circulation through respiratory tract, with after hemoglobin affinity, generate carbon monoxy hemoglobin, thereby weaken blood to the function of respectively organizing delivery of oxygen, harm central nervous system, cause people's the dysfunction such as sensation, reaction, understanding, memory, severe one harm blood circulation system, causes life risk.So, even trace sucks carbon monoxide, also may cause fearful Hypoxic injury to people.
Nitrogen oxide: nitrogen oxide mainly refers to nitrous oxide, nitrogen dioxide, they are all harmful gas, particularly respiratory system are had to harm.In content of nitrogen dioxide is the air of 9.4 milligrams/cubic metre, expose 10 minutes, can cause people's respiratory system functional disturbance.
Hydrocarbon: at present not clear its direct harm to health.But work as nitrogen oxide and hydrocarbon under the effect of solar ultraviolet, can produce a kind of irritating light blue smog that has, wherein include the Various Complex compounds such as ozone, aldehydes, nitric acid lipid.To human body, the most outstanding harm is to stimulate eyes and upper respiratory tract mucous membrane to this photochemical smog, causes inflamed eyes and laryngitis.In December nineteen fifty-two, there is photochemical smog in London, the death toll more long-term same period of many 4000 people in 4 days, and above death in 45 years old is maximum, is about at ordinary times 3 times; 1 year old following at ordinary times 2 times that are about.
Plumbous: lead is poisonous heavy metal element, and gasoline great majority are mixed with detonation suppressor tetraethyllead or lead methide, the lead and the compound thereof that after burning, generate are toxic substance.Lead in urban atmosphere more than 60% from the burning of automobile doped fuel.In human body, lead content exceeds standard and can cause disease of cardiovascular system, and affects function and the nervous system of the vitals such as liver, kidney.Because lead dust is than great, conventionally accumulate in the air of about 1 meter height, therefore maximum to children's threat.
Tail gas, when being directly detrimental to health, also can exert far reaching influence to human lives's environment.Sulfur dioxide in tail gas has strong impulse smell, easily causes the generation of " acid rain " while reaching finite concentration, causes soil and water source acidifying, affects the growth of crops and forest.Over nearly 100 years, greenhouse effect have become the mankind's a blight.Melting Glaciers:, sea level rise, EI Nino phenomenon, La Nina Phenomenon etc. have all been brought very stern challenge to the mankind's existence.Carbon dioxide is the arch-criminal who causes greenhouse effect.
Ternary catalyzing unit, is mounted in most important outer purifier in automobile exhaust system, CO, HC and NO that it can be discharged vehicle exhaust
xdeng harmful gas, by oxidation and reduction, change harmless carbon dioxide, water and nitrogen into.When the vehicle exhaust of high temperature passes through purification plant, the purifying agent in ternary catalyzing unit will strengthen CO, HC and NO
xthe activity of three kinds of gases, impels it to carry out certain oxidation-reduction chemical reaction, and wherein CO is at high temperature oxidized into colourless, nontoxic carbon dioxide; HC compound is at high temperature oxidized to water (H
2o) and carbon dioxide; NO
xbe reduced into nitrogen and oxygen.Three kinds of harmful gases become innocuous gas, and vehicle exhaust is purified.
