Description
Technical field
The invention belongs to motor vehicle exhaust emission contamination control and air pollution treatment field, its technology contents is related to one kind can
For removing the synthesis solution method of particulate pollutant in vehicle exhaust.
Background technology
In recent years since, haze weather occurs repeatedly in each big city in China, and the arch-criminal for causing the problem is exactly in air
Pollution particulate matter（PM）.In general, particulate pollutant can be divided into PM10, PM2.5, PM1, PM0.5 etc. no according to its diameter
Same rating-type.Wherein, PM2.5 pellets because its quantity it is larger, be to cause atmospheric haze and respiratory disease
Dominant particle pollutant.In numerous airborne particulates emission sources, motor vehicle exhaust emission is mostly important discharge
One of source, the quick raising of rapid development and living standards of the people in particular with national economy, the ownership of automobile
Rapidly rise, motor vehicle exhaust emission pollution problem also getting worse.Research shows, the Vehicle Exhaust Particulate being discharged into air
Atmospheric haze is not only resulted in, can also be made a very bad impression to respiratory system etc., seriously endangers health.
In general, the method that essence reduces Vehicle Exhaust Particulate discharge mainly has two kinds, first, being fired by improving
The combustion quality and the more clean alternative fuel of searching of material discharge to achieve the purpose that to reduce；Second, by automobile engine
Improved, to improve the efficiency of combustion of fuel, so as to reduce exhaust emissions particulate matter.However, either fuel quality carries
Height, the research and development of alternative fuel, or the improvement of engine, are required for expending substantial amounts of human and material resources and time, in a short time all
It is difficult to solve the problems, such as that motor vehicle exhaust emission exists.Moreover, for the vehicle being currently in operation, its exhaust emissions problem
It can not be solved by the method that engine is improved.Just because of this, vehicle exhaust particulate burning purifying device is because of its technical process
Simply, simple installation, clean-up effect are notable and can solve the problems, such as vehicle exhaust particulate emission in a short time and be subject to each side's weight
Depending on.
However, being purified for vehicle exhaust particulate pollutant, currently known technical method is to use to be based on absorption-burning
" particle trap " of principle carries out, although this method has the advantages that simple installation, significant effect, there is also tail gas row
It is big to put resistance, adsorption layer easily blocks, and combustion process influences operation, and expensive catalyst, requires fuel sulfur content high a series of
Defect, causes it still can not be able to large-scale promotion application.Efficient, price is run in order to possess automobile tail gas purification system
The features such as cheap, adaptable, really meet the needs of large-scale promotion application, the present invention is net for existing vehicle exhaust particle
It is insufficient existing for change technology, using Promethean technical solution, construct a kind of vehicle exhaust particle and remove system, with solution
Exhaust emissions resistance existing for certainly existing vehicle exhaust particulate burning purifying technology is big, and adsorption layer easily blocks, and burning deashing process influences
Operation, involves great expense, and the problems such as high is required to fuel sulfur content, makes it have and runs the spy such as efficient, cheap, adaptable
Point, thus reduce or eliminate exhaust particulate cleaning system in actual use there are the problem of, reduce its practical application
Threshold, reaches the requirement of large-scale commercial popularization and application.
The content of the invention
In order to overcome deficiency and problem existing for existing vehicle exhaust particulate burning purifying technology, the present invention provides one kind to be used for
Remove the Technical Solving of Vehicle Exhaust Particulate.This method has efficient operation, operational outfit cost relative moderate, adapts to
The features such as property is strong, is very suitable for the technical solution as Vehicle Exhaust Particulate clarifier, the technical solution one
Denier is implemented, it would be possible to solves the problems of conventional vehicle exhaust particulate burning purifying device, this technology is advised greatly rapidly
Mould promotes and applies, so as to produce good trade benefit and social benefit.
The technical solution adopted by the present invention to solve the technical problems is：（1）Using electrostatic precipitator technology as major technique hand
Section, for removing finely ground particles present in vehicle exhaust.Due to compared to other particle capture technologies, electrostatic precipitator technology
Adsorbent and catalyst need not be used, therefore it is to the adaptable of smoke components, to fuel sulfur content without particular/special requirement, and not
The problems such as adsorbent obstruction can be produced because of the accumulation of particulate matter, causes exhaust emissions resistance to increase, system operation is stablized relatively,
Can be as the technical way for removing vehicle exhaust particle.（2）Removed using mobile generator as vehicle exhaust particle electrification
The power supply source of system, and low-voltage AC is converted to the high voltage direct current of 15~20kv by use silicon rectifying transformer.（3）Set
Surge tank is vented, to slow down vehicle exhaust flowing velocity, the residence time of increase tail gas in the electric field, enables particulate matter more
Ground is captured by dust collector pole, so as to improve removal efficiency.（4）Electric-heating-wire-heating is wound outside dust collecting pole plate to burn to particle,
Particulate matter after burning is converted into the gases such as carbon dioxide and carries out cleaning discharge.
The technical characteristics that the present invention has are：（1）Compared with existing exhaust particulate thing removal technology, whole particle
Thing removal process does not use suction type and catalysis combustion system, without adsorbent and catalyst is used, can avoid blocking, fuel oil
High cost problem caused by bad adaptability and expensive catalyst.（2）There is provided exhaust buffer unit, reduces exhaust gas flow speed
Degree, adds residence time of the flue gas in electrostatic field, enables particulate matter in flue gas fully charged, and make electrically charged particle two
There is the traveling time of abundance between pole plate, particulate matter is captured as much as possible, so as to improve removal efficiency.（3）Receiving old pole
There is provided electric-heating-wire-heating, with the dust collector pole particulate matter that burns, on the one hand can reduce the excessively multipair electric-field strength of dust collector pole focusing particles
The influence of degree, on the other hand can make particulate matter be converted into gas and carry out harmless discharge.
