If the pollutant type in the first monitoring region 405 is industrial waste gas, the pollution species in the second monitoring region 406Type is pollution-free (bullet train is travelled to the preferable areas covered with forests of air quality), and third monitors the pollutant in region 407Type is vehicle exhaust, and bullet train is travelled to the right by the left side of Fig. 4.Then the first monitoring region 405 is driven into bullet trainBefore, the industrial waste gas strainer in strainer library is switched into working condition, to use Industry Waste in the first monitoring region 405Air filter net is filtered the industrial waste gas in the air-flow of inlet channel；Before bullet train drives into the second monitoring region 406,Whole strainers in strainer library are switched into stand-by state, so as to second monitoring region 406 in be directly sucked in air quality compared withGood air；Before bullet train drives into third monitoring region 407, the vehicle exhaust strainer in strainer library is switched into workState, to be carried out in third monitoring region 407 using the vehicle exhaust in air-flow of the vehicle exhaust strainer to inlet channelFiltering.
It by adopting the above technical scheme, can be to air cleaning system when bullet train is travelled to different Polluted areasIn strainer switch over, to be filtered to the pollutant in Polluted area using corresponding strainer, improve air cleaningEfficiency.
In addition, for same pollutant, pollution level is also not quite similar.For example, in some big city vehicle exhaustsConcentration is higher；And in some small cities, the concentration of vehicle exhaust is relatively low.For same pollutant, can be set for strainerSet different filtering ranks.For example, can be carried out using the filtering higher strainer of rank for polluting more serious regionFilter；For polluting lighter region, can be filtered using the filtering lower strainer of rank.
Specifically, the data processing unit is also used to the air matter acquired to first air quality monitoring unitAmount information is analyzed, and determines the filtration grade of strainer corresponding with the air quality information；The strainer control unit,It is also used to use shape of the filtration grade to strainer in the strainer library of basis strainer corresponding with the air quality informationState switches over, wherein the pollutant of the filtration grade of in running order strainer and first monitoring region after switchingConcentration matches.
In an advantageous embodiment, bullet train air cleaning system further include: speed adjustment unit, for according to instituteThe pollutant type for stating the first monitoring region, is adjusted the travel speed of the bullet train.
For example, will not influence the pollutant of visibility for vehicle exhaust, industrial waste gas etc., the traveling of train can be improvedSpeed is to accelerate to pass through Polluted area；Flue dust, sand and dust generated for large area straw burning etc. influence the pollutant of visibility,Need to reduce the travel speed of train, to ensure the traffic safety of train.
Preferably, the strainer in strainer library can be configured according to the travel route of bullet train.For example, in Jing-Hu RailwayUpper main pollutant is vehicle exhaust and industrial waste gas, then only needs to install vehicle exhaust strainer and industrial waste gas in strainer libraryStrainer；Main pollutant is the flue dust and sand and dust that straw burning generates on Lan Xin line, then only needs to install straw in strainer libraryStalk combustion fumes strainer and sand and dust strainer, to improve the utilization rate of strainer.
