Description
Technical field
The utility model relates to automobile dust collecting equipment field, especially a kind of adsorbent equipment of new and effective Vehicle Exhaust Particulate.
Background technique
In recent years, the people living in large-and-medium size cities more and more pay close attention to air quality problems, and the new term such as haze, PM2.5 and new ideas also become hot issue.I shuttles back and forth in the down town of prosperity every day, often by the bus that emits black smoke and truck at a loss as to what to doly smoked, especially some diesel vehicles are emerged when traffic light intersection starts a burst of black smoke, almost allow people suffocate." Volkswagen's tail gas door " event of global concern is enjoyed more to cause my interest to the improvement of high pollution exhaust gas from diesel vehicle for the previous period.
Exhaust gas particulate in petrol engine mainly contains three kinds of sources: the sulphate that the lead in doped fuel, organic fine particles (comprising soot) are produced by chemical change with the element sulphur in gasoline.The petrol engine organic fine particles discharge good to adjustment only just can run into when using dense mixed gas, and generally adopts unleaded gas at present, so few relative to the Particulate Emission of diesel engine petrol engine.Diesel particulation is the variable complex mixture of a kind of composition.It includes the particulate that directly produces from diesel engine combustion and entering in the process of air from outlet pipe, especially in equipment for after-treatment, gaseous state, a series of chemistry or physical change occurs and the particulate that produces between liquid state and solid state chemistry composition.It mainly comprises the impurity such as soot, higher boiling point hydrocarbon compound, sulphate, the water be combined with sulphate and the dust containing metal ingredient based on carbon.Wherein, the condition that solid carbon smoke particle DS (drysoot) generates is high temperature, although diesel engine is oxygen-enriched combusting always, but because fuel oil is uneven with mixing of air, ischaemia causes the generation of soot, and unburned fuel concentration is higher, and temperature is higher, the formation speed of soot is also higher, and diesel particulate emission increases; On the other hand, temperature is higher, and oxygen concentration is higher, and the oxidized effect of diesel particulation is also more remarkable, and therefore final particulate growing amount just can reduce.Therefore can think that final diesel particulate emission amount is determined by the competition of its generation and oxidizing process.Higher boiling point hydrocarbon compound is not firing and imperfect combustionly becoming to be grouped into by fuel oil and lubricant oil, it is adsorbed on the surface of carbon granule, by organic solvent dissolution, extraction, therefore dissolved organic matter SOF (solubleorganicfraction) can be also referred to as.The element sulphur of sulphate then mainly in diesel oil is produced by chemical change, and its proportion is little.
Increasing NULL and epidemiological study show: particulate has a significant impact health.The particulate of different-grain diameter is different with the sedimentation rate in body at air, the particulate being greater than 2.5 μm (PM2.5) has higher sedimentation rate at the upper respiratory tract, the particulate that particle diameter is less than 2.5 μm (PM2.5) is higher in lung's sedimentation rate, ultrafine dust even has higher sedimentation rate in bronchus, and sedimentation rate can raise along with the reduction of particle diameter.Particulate is less, and the time be suspended in air is longer, and the chance of particulate and human contact is larger, too increases particulate and absorbs sunlight and other material effects in an atmosphere and the chance that produces chemical reaction.In addition, larger than the simple structure aggregate specific surface area be made up of larger particles by the labyrinth aggregate formed compared with fine particle, so the heavy metal more easily adsorbed human health and organic substance, thus its bio-toxicity is larger.According to statistics, in Europe, PM2.5 causes 38.6 ten thousand people dead every year, and makes European Union member countries' average life expectancy reduce 8.6 months.China has 600,000 people to die from lung cancer every year, and lung cancer morbidity rate increases by 26.9% every year, as taken measures not in time, the patients with lung cancer expecting China in 2025 will reach 1,000,000, become the first in the world lung cancer big country, international cancer mechanism of the World Health Organization confirms, the PM2.5 particulate matter discharged in diesel car and lung cancer, carcinoma of urinary bladder are relevant.The data display of other research institutions, the reason that more and more many non-smokers suffer from lung cancer is relevant with the PM2.5 particulate matter discharged in diesel automobile exhaust.
In air, the source of PM2.5 is widely, however mathematical be vehicular engine (particularly diesel engine) be one of the important sources of PM2.5 in air.The exemplary diesel engine Particulate Emission quality that Kittelson research obtains and the size distribution of number concentration, the current diesel engine particulate of discharging is no matter in quality with quantitatively all occupy great proportion., point out in the PM2.5 origin analysis report of Beijing's issue in 2014: in annual PM2.5 source, Beijing, area transmissions contribution accounts for 28-36%, and local disposal of pollutants contribution accounts for 64-72% meanwhile.But in local pollution contribution, Motor Vehicle, fire coal, industrial production, airborne dust are main source, account for 31.1%, 22.4%, 18.1% and 14.3% respectively, and other discharges such as food and drink, motor vehicle repair, livestock and poultry cultivation, architectural finish account for 14.1% of PM2.5.So for improving China's urban air-quality, reducing PM2.5 in air, effectively eliminating small particle emission of diesel car is a key link.
At present, the purification technics strategy of diesel particulation can be divided into two classes substantially: emission controls by improving combustion and external purification.Emission controls by improving combustion refers to the Production and emission amount being reduced source particulate in engine cylinder by air intake pressurized, high-pressure injection and cylinder barrel-piston ring-strategic management of technology such as piston triplicity structure and material improvement.But emission controls by improving combustion measure can effectively reduce Particulate Emission, but owing to one being that the consumption of lubricant oil can only reduce to certain degree, any one motor can consume lubricant oil; Two is that emission controls by improving combustion is mainly fully mixed into object with oil gas, and if the minimizing of high compression injection techniques to large particulate increases fine particles quantity for cost, and the harm of fine particles to human body and environment is larger; Three is reduce between particulate and the discharge reducing NOx to there is certain contradiction.Only rely on the improvement effect of emission controls by improving combustion technology to diesel particulate emission to be restricted, be difficult to the requirement for cleaning adapting to future automobile, external purification technology must be taked simultaneously.At present, the microparticle machine external purifying of research both at home and abroad mainly contains plasma cleaning, solution cleaning, centrifugation and particle trapper and electrostatic separation etc.
(1) plasma cleaning technology: plasma cleaning technology is a kind of new Diesel Engine Exhaust Purification technology, and this technology can reduce the multiple harmful components in diesel exhaust gas simultaneously.Utilize plasma chemical reaction purifying exhaust air technique functions to start from early eighties, be mainly used in fixing gas outlet means, generator and boiler etc.Along with the continuous renewal of technology, people started the exhaust emissions purification this technology being applied to diesel engine in recent years.Harmful components in diesel exhaust gas are through plasma reactor, and complicated chemical reaction can occur, and wherein NO is easy to be oxidized to NO2.Researcher because NO2 has very strong oxidability, at diesel exhaust gas temperature, soot particle can be oxidized to the oxide of carbon, so it has been generally acknowledged that the reduction of soot particle is caused by the generation because of NO2.
(2) Aqueous Solution Cleaning Technology: Aqueous Solution Cleaning Technology is the method allowing exhaust be cleaned particulate by water or oil.This method is simple, is suitable for the gas outlet means fixed.Sweden researcher once attempted the outlet pipe of diesel engine for automobile to make Venturi tube, and utilize the negative pressure at trunnion place to suck in exhaust by moisture, the particulate during dilution and cleaning are vented and NOx, obtain certain effect.
(3) centrifugal separation technology: centrifugal separation technology is introduced in cyclone separator exhaust, utilizes the centrifugal force of particulate, separated by particulate from air-flow.Because diesel particulation is very little, diameter mostly below 1 μm, this technology can only separating particles 5% ~ 10%, effect is poor.
(4) particle trapper: particle trapper (DPF, dieselparticulatefilter) be current a kind of diesel particulate emission after-treatment applications mode the most widely, in the world eighties of last century seventies is started to the research of particle trapper, now progressively form commercial prod.The automobile of first use particle trapper is the car exporting to California, USA of German Benz Co. in 1985 production.Increasingly strict along with Abgasgesetz, the diesel-oil vehicle that nowadays particle trapper is installed by developed country gets more and more, as microparticles collection device installed by the part passenger cars such as Audi, masses and benz.At present, comparative maturity and apply more product be U.S. CORNING (Corning) company and Japan NGK company produce honeycomb ceramic filter particle trapper.The continuous catalysis regeneration of particle catcher of the JohnsonMatthey company exploitation of the U.S. receives publicity with high arresting efficiency and regeneration efficiency.
Particle trapper carries out trap filter mainly through four kinds of physical effects such as diffusion mechanism, interception mechanism, inertial collision mechanism and gravity sedimentation mechanism to particulate.Its conventional filtering material has ceramic-base, metal base and composite base three major types.Although to be diesel engines at present exhaust micro particle a kind of for particle trapper effectively and application post-treatment measure very widely, but due to this kind of measure to the purification efficiency of particulate and filter geometrical construction closely related, if want to obtain higher micro particle filtering efficiency, need to increase the geometric parameters such as the volume of filter and porosity ratio, this will make the volume of catcher increase on the one hand undoubtedly, be unfavorable for that car load is installed and arranged, and application cost also can increase substantially; Also can cause extreme influence to the former machine vent systems of motor on the other hand, the power character of former machine and Economy are sacrificed.
Although diesel particulates is on the whole in electroneutrality, the particulate of about 85% is all charged particle, and each charged particle has 1 ~ 5 basic positive charge or negative charge.The specific resistance of diesel particulates changes in 106 ~ 108 Ω/cm orders of magnitude, is therefore applicable to utilizing electric field to carry out Electrostatic Absorption to exhaust gas particulate, reaches the object of particulate purification.Namely set up High Voltage electric field in an exhaust gas, when exhaust airstream flows through electric field, charged particle is adsorbed by opposite electrode respectively.If install charge device additional in the front end of catcher, make particulate charged artificially, charged particle flow is deposited by adsorbing when catcher as opposite electrode, and Electrostatic efficiency also can be greatly improved.Meanwhile, this technology, owing to can not produce obvious impact to engine exhaust system, is conducive to the maintenance of former mechanomotive force and economic performance.
Therefore, research purpose of the present utility model is: exploitation particulate electrostatic separation system, and the exhaust particulate thing content that diesel engine for automobile is discharged reduces, and solves the PM2.5 pollution aggravation problem that the continuous growth along with large-scale logistics transportation diesel-oil vehicle causes.Research Thinking is: boost to vehicle power output voltage, and acts on the small-sized adsorber with coil or wire netting by voltage after boosting, and the particulate matter in vehicle exhaust is trapped in its surface in the mode of Electrostatic Absorption.Then by changing voltage swing, the adsorption and desorption rule of particulate, collecting being separated the particulate matter after coming off, realizing recycling of adsorber.
Of the present utility modelly to have a extensive future, along with the raising of people's living standard, increasing sharply of automobile quantity, the harm that vehicle exhaust produces is also more and more serious, certain infringement is all caused to ecotope balance and human body health, be mainly manifested in the increase of human body illness rate and the generation of photochemical smog, should pay attention to the pollution of vehicle exhaust in time and strengthen auto-emission control and improvement.Since meanwhile diesel engine came out from 1892, on various power plant and vehicle, obtain increasingly extensive application by means of its good power character, Economy and durability etc. advantage.Europe and Japan just achieve the dieselization of cargo vehicle and motorbus substantially at 20 century 70s.Predict according to external appropriate authority, between 2001-2014 years 15 years, Global Auto market total scale will increase by 39%, and wherein gasoline car increases by 23%, and diesel-oil vehicle increases by 97%.With its significant oil-saving effect and can meet the maximum discharge standard improved constantly, diesel-oil vehicle obtains the great attention of European Union, the U.S., Korea S, India, Japan and other countries, and the diesel oilization of automobile becomes a kind of trend gradually.But along with diesel-oil vehicle increasing number, cause exhaust gas from diesel vehicle exhaust emission day by day serious, so the adsorbent equipment market prospects of exploitation Diesel exhaust particles extracts are very wide.
