Abstract
The utility model discloses an automobile exhaust silencer with purification effect, which is composed of two cylindrical nets. An inner net is provided with a refluxing hemisphere, which makes the exhaust permeate towards an outer net via the catalysts, and enter the outer layer of a two-stage purifying chamber via the air hole of a connecting end cover. The exhaust is expelled to a silencing chamber via a catalyst layer from an inner net pipe, so two-stage purifying and three-stage silencing action is achieved. The silencer with purification effect has the property of adapting to the high height above sea level, strong radiation, low atmospheric pressure and thin oxygen in the plateau region, and has a better effect in the plain region.
Description
The utility model is a kind of engine exhaust purifying muffler, is particularly useful for the exhaust purging muffler of automobile.
Along with the develop rapidly of communication, waste gas sent off from automobiles befouling environment and noise problem have become one of social effects of pollution.At present, homemade various vehicle generally has only noise elimination and does not have purification plant; Imported vehicle is because of problems such as life time, and blowdown exceeds standard also very serious.Recently several automobile exhaust gas purifying silencer of report have also proposed some solutions at this point, and as two cylinder type automobile exhaust gas purifying silencing apparatuss etc., but structure is comparatively complicated, and are not suitable for the plateau section and use.
The purpose of this utility model provides a kind of improved exhaust gas purification silencer, and it can play the effect of three grades of noise eliminations of two-step purification, and fuel-economizing, economizes merit, adapts to plateau climate.
The utility model is by the inside and outside guard of suction tude (1), circular housing (4), coaxial line, be filled with catalyst layer (14) and anechoic room and form between inside and outside guard, the end that is provided with a suppression ring (5), interior guard I in the interior guard I (3) is equipped with backflow hemisphere (7).The catalyzer that is adopted is rare earth, alkaline earth, crosses the plating composite, is provided with the first and second two expansion cavities in the anechoic room, has the elongated hole that staggers mutually on outer guard, the interior guard.
Below in conjunction with an embodiment shown in the drawings, the utility model will be further described, but summary of the invention is not limited to shown in the accompanying drawing.
Fig. 1 is the structural representation of automobile exhaust gas purifying silencing apparatus.
Fig. 2 is outer guard II structural representation.
Fig. 3 is interior guard II structural representation.
Suction tude (1), outer end cap I (2), interior guard I (3), shell (4), suppression ring (5), outer guard I (6), backflow hemisphere (7), packing ring (8), inner end cap (9), jam (10), nut (11), screw (12), locating stud (13), catalyzer (14), outer guard II (15), interior guard II (16), inner end cap II (17), anechoic room (18), dividing plate (19), outer end cap (20).Purifying muffler can replace former automotive muffler, and is consistent with the engine exhaust pipe caliber, is convenient to connect, and the mounting point is constant.The gas that outlet pipe is discharged flows into behind the Intranet cover because the effect of suppression ring and backflow hemisphere sees through catalytic layer from interior webmaster spreads towards periphery, enter second level skin by connection end cap pore and flow to anechoic room discharge tail gas through catalytic layer from interior pipe again, anechoic room is divided into first and second expansion cavities by dividing plate (19).Cleaning catalyst for tail gases of automobiles uses precious metal usually, and this catalyzer has active good, the advantage that the life-span is long, but, make catalyzer by advance copy model utility employing rare earth, alkaline earth, transition metal composite because rareness is expensive, conversion ratio is just high down at a high speed.Cheap, material source is wide, has the activity and the chemical stability of platinum element catalyst equally, and forces down at the middle and slow speed of revolution lower back, does not influence power and descends, and experimental result is as shown in table 1.
The utility model has been realized three grades of noise eliminations of two-step purification owing to be provided with the mechanisms such as suppression ring and backflow hemisphere, and it is low to purify the noise elimination value, also can improve the power of engine and reduce oil consumption. Fuel-economizing, province's merit. It is above sea level high that this kind purifying muffler has the highlands of adaptation, the performance that the width of cloth is penetrated by force, air pressure is low and oxygen is thin, and then effect is better to the plains region, and furthermore its volume is littler, and weight is light, and is strong to pavement of road and speed of a motor vehicle variation adaptation power. Especially price is low, estimates that every price is 270～300 yuan, has good market sale prospect.
Claims (2)
1, a kind of automobile exhaust gas purifying silencing apparatus, inside and outside guard by suction tude (1), circular housing (4), coaxial line, catalyst layer that is filled with between inside and outside guard (14) and anechoic room are formed, be provided with a suppression ring (5) in the guard 1 (3) in it is characterized in that, the end of interior guard 1 (3) is equipped with backflow hemisphere (7), anechoic room is provided with the first and second two expansion cavities, has the elongated hole that staggers mutually on outer guard, the interior guard.
2, automobile exhaust gas purifying silencing apparatus as claimed in claim 1 is characterized in that the catalyzer that is adopted is rare earth, alkaline earth, transition metal composite.
