Abstract
The utility model relates to a low-noise and low-pollution exhausting and silencing device, which belongs to the exhausting and silencing device of the engine of the vehicle. The low-noise and low-pollution exhausting and silencing device is characterized in that silencing and pollution discharge are integrated; the casing of the low-noise and low-pollution exhausting and silencing device is composed of a front cover (3) which is provided with an air inlet (1) and a small air hole (2), a housing (7), a rear cover (8) which is provided with an air outlet (10) and the small air hole (9); an exhausting pipeline (4) is arranged in the casing (4); honeycomb pottery (6) which is coated with catalyst is arranged in the pipeline of the exhausting pipeline (4), and a heat insulating pad (5) is arranged between the honeycomb pottery and the exhausting pipeline. Since the honeycomb pottery is made from porous materials; the honeycomb pottery has resistance silencing function and resistance silencing function to air stream; the catalyst has catalytic function to pollutants, and accordingly, the low-noise and low-pollution exhausting and silencing device has favorable silencing function and pollution discharge effects.
Description
The low novel exhaust silencing apparatus that pollutes of the low noise of the invention belongs to the vehicle motor exhaust silencer.
Along with the continuous increase of vehicle, the exhaust sound of motor and pollution constitute the severe contamination to physical environment day by day.Yet, to the exhaust sound of vehicle motor, mostly adopt the way that silencing apparatus is set behind relief opening at present.But its effect of present silencing apparatus is also not really desirable, moreover exhaust contaminant (CO, HC, Nox etc.) great majority are not taked treatment measures, though there is minority also to take some technical measures, all is provided with respectively separately with silencing apparatus.
The purpose of the invention is to develop a kind of noise that will reduce and pollutes the novel exhaust silencing apparatus that is integrated in one with reducing, and to reduce weight and volume, simplified structure and technology reduce cost, and improve contaminant removal effectiveness and noise elimination effect.
The low novel exhaust silencing apparatus that pollutes of the low noise of the invention is the honeycomb that scribbles catalyzer to be made pottery be installed in the engine exhaust pipeline, concrete formation is, the protecgulum that has suction port, shell, the bonnet three who has the air outlet constitutes housing, exhaust duct places in the housing, 1 to 3 the honeycomb pottery that scribbles catalyzer places in the exhaust duct, the installation position that first honeycomb of exhaust duct inlet end is made pottery determined by the engine exhaust amount, and the 2nd the 3rd honeycomb made pottery and be placed on air-flow and shrink to reach after flowing out through previous honeycomb pottery throttling and expand on the perfect substantially position again.
The invention is owing to the honeycomb pottery that will scribble catalyzer places in the exhaust duct, the honeycomb pottery itself is a porous material, can play the resistance noise reduction effect, simultaneously air-flow is produced the effect of throttling, expansion, can reach the reactive muffling purpose, urge and do agent and can play catalysed oxidn exhaust contaminant (CO, HC, Nox etc.), can play the catalytic reduction effect again, therefore, the silencing apparatus of the invention has the double action of eliminating the noise and reducing pollution concurrently, and respond well.
Accompanying drawing 1, the low a kind of example structure schematic representation that pollutes the novel exhaust silencing apparatus of low noise.
Accompanying drawing 2 is the A-A view of accompanying drawing 1
Accompanying drawing 3 is the B-B sectional view of accompanying drawing 1.
Accompanying drawing 1 is that (being in the inner casing) is equipped with the example structure schematic representation that two honeycombs are made pottery in the exhaust duct.Structure and installation according to this accompanying drawing narration the invention.By accompanying drawing as can be known, the composition structure of this silencing apparatus is, shell (7) front end is connected with the protecgulum that has suction port (1) (3), the rear end is connected with the bonnet that has air outlet (10) (8), exhaust duct (4) less than internal diameter of outer cover places in the exterior sheath conduit, between exhaust duct and the shell air flue is arranged, the spilehole (9) that spilehole (2) that this air flue and protecgulum end circumference are furnished with and bonnet end circumference are furnished with communicates, so that cool air passes through, the honeycomb pottery (6) that scribbles catalyzer is installed in the exhaust duct, between honeycomb pottery and the exhaust duct thermal insulating pad (5) is arranged, first honeycomb of exhaust duct entrance point is made pottery and is determined by the engine exhaust amount apart from the distance of protecgulum, making pottery with the 3rd honeycomb for second is installed in air-flow and makes pottery out from previous honeycomb, is advisable on the position after improving of expanding again.
The exhaust duct of the silencing apparatus of the invention adopts two semicircle housings that have fillet to constitute, and links up with the fillet of bolt (11) with two semicircle housings, and the fillet external diameter equates with internal diameter of outer cover, exhaust duct can be supported on the shell.In addition, shell and former and later two lids also are that bolt (12) couples together, so the muffler of the invention, dismounting, maintenance are all convenient.Also be convenient to simultaneously change wherein some parts.
Accompanying drawing 2 is A-A views of accompanying drawing 1, and number in the figure (13) is the spilehole (2) of accompanying drawing 1.
Accompanying drawing 3 is B-B sectional views of accompanying drawing 1.Number in the figure (14) is the inner casing connecting bolt (11) in the accompanying drawing 1, and label (15) is the shell connecting bolt (12) in the accompanying drawing 1.
Claims (5)
