Abstract
The utility model discloses a catalysis silencer which comprises a cylinder, a front end cover and a rear end cover are installed on two sides of the cylinder, the front end cover is provided with an air inlet pipe, the rear end cover is provided with an air exhaust pipe, a mixing chamber, a transition chamber and an air exhaust chamber are sequentially placed inside the cylinder, a porous barrier is located inside the transition chamber, and two groups of carriers are placed on the porous barrier. The catalysis silencer can achieve sound elimination and exhaust gas emission of heavy type vehicles, and meets environment-friendly requirements.
Description
Technical field
The utility model relates to a kind of silencing apparatus, particularly a kind of heavy goods vehicles catalytic muffler.
Background technique
Silencing apparatus is an important composition in the automobile exhaust system.In form, common branch has resistive (shape), resistance (shape), plyability etc.Wherein, dissipative muffler mainly is made up of perforated tube, acoutic fibre board (acoustical cotton).The latter's sound-absorption coefficient changes with change in physical such as density, diameter, that is to say, fibre density is big more, and diameter is more little, and sound-absorption coefficient is high more.The size of sound-absorption coefficient value is related to the effect of whole silencing apparatus again, certainly, influence a plurality of factors such as section girth, effective length, cross-sectional area of the silencing apparatus in addition of noise elimination effect, and girth, effective length are big more, and the noise elimination effect is good more.
Because heavy goods vehicles in the research and development and the production of China, in order to adapt to environmental protection requirement, needs exploitation to be applicable to the silencing apparatus of heavy vehicle.
Summary of the invention
The purpose of this utility model is, a kind of new catalytic muffler is provided.
In order to realize above-mentioned task, the utility model is taked following technical solution:
A kind of catalytic muffler comprises stack shell, and there are front cover and rear end cover in the stack shell both sides, suction tude is arranged on front cover, outlet pipe is arranged on rear end cover, it is characterized in that, mixing chamber, transition chamber and exhaust chamber are arranged in stack shell successively, dividing plate is arranged in transition chamber, two groups of carriers are arranged on the porous barrier.
Other characteristics of the present utility model are:
Aperture on the described porous barrier evenly distributes.
Catalytic muffler of the present utility model can satisfy the noise elimination and the exhaust emissions of heavy goods vehicles, and reach environmental requirement.
Description of drawings
Fig. 1 is a catalytic muffler structural representation of the present utility model.
Mark among the figure is represented respectively: 1', air-flow, 1, stack shell, 2, suction tude, 3, exhaust chamber, 4, transition chamber, 5, outlet pipe, 6, mixing chamber, 7, front cover, 8, rear end cover, 9, porous barrier, 10, two groups of carriers.
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
Referring to Fig. 1, present embodiment provides a kind of concrete structure of catalytic muffler, comprise stack shell 1, there are front cover 7 and rear end cover 8 in stack shell 1 both sides, on front cover 7, be provided with suction tude 2, outlet pipe 5 is arranged on rear end cover 8, mixing chamber 6, transition chamber 4 and exhaust chamber 3 are arranged in stack shell 1 successively, porous barrier 9 is arranged in transition chamber 4, two groups of carriers 10 are arranged on the porous barrier 9.
In the present embodiment, the aperture on the porous barrier 9 evenly distributes.
A kind of catalytic muffler of present embodiment, its working principle is: the fog 1' of waste gas that motor car engine is discharged and spraying system ejection enters from suction tude 2, after suction tude 2 enters transition chamber 4 mixing, carry out chemical reaction, by the erasure effect of aperture generation uniformly on the porous barrier 9 in the transition chamber 4, and enter mixing chamber 6, waste gas is decomposed into nitrogen, water and carbon dioxide, afterwards by the two groups of carrier 10 filterings solid particle wherein on the porous barrier 9 in the transition chamber 4, and with two groups of carriers 10 in reactions such as noble metal palladium, enter in the air through outlet pipe 5 again with exhaust chamber 3 UNICOMs.
Claims (2)
1. catalytic muffler, comprise stack shell (1), there are front cover (7) and rear end cover (8) in stack shell (1) both sides, suction tude (2) is arranged on front cover (7), outlet pipe (5) is arranged on rear end cover (8), it is characterized in that, mixing chamber (6), transition chamber (4) and exhaust chamber (3) are arranged in stack shell (1) successively, wherein, porous barrier (9) is arranged in transition chamber (4), two groups of carriers (10) are arranged on the porous barrier (9).
2. catalytic muffler as claimed in claim 1 is characterized in that, the aperture on the described porous barrier (9) evenly distributes.
