Abstract
The invention discloses a silencer capable of filtering PM2.5 and haze. In a car silencer, PM2.5 and haze filters are added to the periphery and the middle of a waste gas inlet pipe and a waste gas discharge pipe, each peripheral filter is made of a circular high-temperature-resistant multilayer waveform metal mesh with gradually decreasing mesh holes, and each middle filter is a PM2.5 and haze filter which is mounted in a filter chamber between the waste gas inlet pipe and the waste gas discharge pipe in a silencer shell. When a car engine operates, waste gas passes the circular filter on the waste gas inlet pipe to allow PM2.5 and haze to be filtered for the first time, the filtered waste gas enters the middle PM2.5 and haze filters for filtering for the second time, the filtered waste gas enters the circular waste gas discharge filter for PM2.5 and haze filtering for the third time and is discharged to the atmosphere through the waste gas discharge pipe. By the silencer, harmful gas emitted by the car engine can be filtered, and environmental protection is achieved.
Description
Affiliated technical field
The present invention relates to a kind ofly can for car engine baffler, filter the device of pm2.5 and haze, especially can filter a kind of pm2.5 of filtration of motor vehicle exhaust emission pm2.5 and haze and the baffler of haze.
Technical background
At present, known car motor silencer discharges a large amount of pm2.5 and haze causes severe contamination to atmosphere, and its mobile muffler only has the setting of eliminating noise, and without the construction and device that filters its motor discharge pm2.5 and haze.Fudan University's chemical research center director Zhuan Guoshun claim: in haze, cause in organic gasoloid (organic hydrocarbon), sulphate (sulfur dioxide), nitrate (nitrogen hydride) and the black carbon four class materials of visibility reduction, wherein organic hydrocarbon, nitrogen oxide and three kinds of materials of black carbon are from motor vehicle exhaust emission, particularly one of black wood charcoal has just reduced by 12% atmospheric visibility, automobile is discharged to such an extent that tail gas has caused pollution of atmosphere from baffler, because only have silencer in its baffler, without filtering pm2.5 and haze device, causes.
In order to overcome that mobile muffler only has silencer and without the deficiency of filtering pm2.5 and haze device, the invention provides and a kind ofly can filter again pm2.5 and a kind of pm2.5 of filtration of haze and the baffler of haze in vehicle exhaust for motor car engine noise reduction.
