Description
Technical field
The present invention relates to auto-emission control technical field, be specifically related to a kind of purifying vehicle exhaust method.
Background technology
Usual automobile is when ratio traveling on shallower highway, harmful gas generally can once be absorbed complete by automobile exhaust purifier that automotive interior is installed preferably, but when pavement roughnesses such as such as hill paths, automobile engine then needs to export bigger power, the tail gas that the comparision contents that now will exhale pernicious gases is many, this automobile exhaust purifier is then difficult to once absorb complete by the harmful gas in tail gas, thus environmental pollution can be caused.
Such as, the nitrogen oxides in vehicle exhaust includes multiple compounds, such as nitrous oxide (N2O), nitric oxide (NO), nitrogen dioxide (NO2), nitrogen trioxide (N2O3) etc..Except nitrogen dioxide, the equal extremely unstable of other nitrogen oxides, meet light, wet or heat becomes nitrogen dioxide and nitric oxide, nitric oxide becomes again nitrogen dioxide, and nitrogen dioxide to be one have corrosive gas.Will there be slight eye and upper respiratory tract irritation at the suction nitrogen dioxide gas initial stage, such as pharyngeal discomfort, dry cough etc., and uncomfortable in chest, respiratory distress then can occur after incubation period a few hours, cough, cough up frothy sputum, cyanosis etc., severe one possibly even can make people faint.
Therefore, how the nitrogen oxides in vehicle exhaust is processed in time, become problem demanding prompt solution.
Summary of the invention
For the deficiencies in the prior art, it is an object of the invention to provide a kind of purifying vehicle exhaust method, it is possible to efficiently control the content of nitrogen oxides in vehicle exhaust, reduce the vehicle exhaust pollution to environment and the injury to human body.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of purifying vehicle exhaust method, comprises the steps:
Obtain the exhaust pressure value in automobile engine exhaust pipe exit；
When described exhaust pressure value reaches predetermined value, the tail gas of automobile exhaust purifier outlet is detected；
Result according to detection judges whether the nitrogen oxide emission in vehicle exhaust exceedes threshold value；
If so, then automobile the second depurator valve is opened, by described motor vehicle exhaust emission to described automobile the second depurator, and by the mode of high electron beam irradiation, the nitrogen oxides in vehicle exhaust is ionized, to realize the double absorption of vehicle exhaust is processed.
Compared with prior art, the purifying vehicle exhaust method of the present invention judges whether to need vehicle exhaust is carried out after-treatment by exhaust pressure value and the nitrogen oxide emission in automobile engine exhaust pipe exit, if then vehicle exhaust being carried out double absorption by the mode of high electron beam irradiation in automobile the second depurator.So that running car does not all have, on the road surface of various environment or electromotor acting is different, the nitrogen oxides that discharge exceeds standard, effectively prevent the vehicle exhaust pollution to environment and the injury to human body.
Accompanying drawing explanation
Fig. 1 is the schematic flow sheet of a kind of purifying vehicle exhaust method in embodiments of the invention.
Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, the present invention is described further:
With reference to Fig. 1, a kind of purifying vehicle exhaust method provided by the present invention, comprise the steps:
Step S101, obtains the exhaust pressure value in automobile engine exhaust pipe exit.Owing to automobile travels or automobile engine produced power difference during automobile speed per hour difference on different roads, so that the exhaust pressure value in automobile engine exhaust pipe exit is also different.During this exhaust pressure value difference, in the tail gas in usual exhaust pipe of engine exit, the content of comprised harmful gas also differs.
Step S102, when described exhaust pressure value reaches predetermined value, detects the tail gas of automobile exhaust purifier outlet.
In the embodiment of the present invention, only just the tail gas of automobile exhaust purifier outlet is detected when exhaust pressure value reaches predetermined value, it is possible to effectively reduced the access times and time that use equipment described in this process, extended the service life of this equipment.
Wherein in an embodiment, the kind and content that comprise harmful gas can be detected in tail gas respectively by multiple detectors.When in the tail gas that automobile exhaust purifier outlet in the unit interval is discharged, the content of institute's harmful gas then illustrates when accounting for total tail gas amount more than or equal to M% that evil gas exceeds standard.This M is positive number, and it can be set according to actual needs.
During due to exhaust pressure value less than predetermined value, the harmful gas in vehicle exhaust would generally automobile exhaust purifier absorb complete after emit.But the situation that vehicle exhaust exceeds standard then likely is there will be when this force value is more than predetermined value.This predetermined value can be determined after testing according to different electromotors.Such as the content by the tail gas in automobile engine exhaust pipe exit is contained harmful gas detects, when this content reaches the absorbent maximum of automobile exhaust purifier institute, the exhaust pressure value in now automobile engine exhaust pipe exit can be sized to this predetermined value.
According to the result of detection, step S103, judges whether the nitrogen oxide emission in vehicle exhaust exceedes threshold value.If then performing step S104.Otherwise return and perform step S101 or step S102.
Wherein in an embodiment, described threshold value could be arranged to 78 milligrams/kilometer.
Step S104, if the judged result of step S103 is yes, then automobile the second depurator valve is opened, by described motor vehicle exhaust emission to described automobile the second depurator, and by the mode (EBDC) of high electron beam irradiation, the nitrogen oxides in vehicle exhaust is ionized, to realize the double absorption of vehicle exhaust is processed.
In the embodiment of the present invention, automobile the second depurator is the device being specifically used to and the various harmful gass in vehicle exhaust carrying out double absorption process, it is possible to be connected to automobile exhaust purifier outlet part.Wherein in an embodiment, in described automobile the second depurator, absorbent for carbon monooxide can also be filled with, for the carbon monoxide processed in tail gas.Concrete, described absorbents of carbon monoxide can be by porous inorganic carrier with its on the compositions that constitutes of the two-element match of the nitride that is loaded with and copper chloride, and in said composition, nitride accounts for 0.45-0.8 mol ratio；Described inorganic carrier includes: porous ceramics, activated carbon or titanium oxide；Described nitride be pyridine andCompositions.
In another embodiment, the described process that the tail gas of automobile exhaust purifier outlet is detected may include steps of:
By the mode of infrared detection, tail gas is detected in real time；
According to absorbed ultrared wave-length coverage and absorbed degree, generate the corresponding signal of telecommunication；
Nitrogen oxide emission is drawn according to this signal of telecommunication analysis.
Owing to vehicle exhaust having generally comprised the various harmful gass such as carbon monoxide, Hydrocarbon, oxygen sulfur compound, oxynitride.And every kind of gas has specific characteristic absorption band and characteristic frequency in these gases, can by strong absorption when infrared spectrum drops near characteristic frequency band time.So can detect the composition of harmful gas in tail gas by the infrared spectrum of individual features frequency, and the amount of absorbed external spectrum can detect the content of corresponding gas.
