Description
Technical field
The utility model relates to automobile exhaust system field, particularly a kind of square chest type catalytic muffler.
Background technique
Along with the increasingly stringent of Abgasgesetz, in diesel engine, control techniques has started to seem unable to do what one wishes, must rely on diesel emission post-processing technology to reduce the discharge of NOx and PM.Many metropolitan pollution of atmosphere turn to coal smoke and automotive composite type to pollute by coal-smoke pollution, and minority megalopolis has obviously shown photochemical smog type (being motor-vehicle tail-gas type) pollution of atmosphere.Therefore, the research of Diesel Emission Control Technologies: and important and extremely urgent.
Selective catalytic reduction system operating SCR(Selective Catalyst Reduction) be to downstream working medium processing system, its principle is exactly to spray into ammonia in the tail gas that contains NOx, urea or other nitrogen-containing compound, make NOx wherein be reduced into N2 and water, be used at present in diesel engine vent gas processing procedure.
Catalytic muffler is parts very crucial in SCR system, an its all-in-one-piece catalysis and silencer, be contained in the stainless steel casing of a sealing, have catalysis and noise elimination function, from the package structure of square chest type catalytic muffler in the market, its catalysis and acoustic attenuation performance are poor, and after long-time use, particle deposition in waste gas is in silencing apparatus inside, and inconvenience is removed, and causes significantly shorten the working life of silencing apparatus.
Model utility content
The purpose of this utility model is to overcome the shortcoming of prior art, a kind of performance that promotes catalysis and noise elimination is provided, is convenient to clear up a kind of square chest type catalytic muffler of deposit seed and long service life.
The purpose of this utility model is achieved through the following technical solutions: a kind of square chest type catalytic muffler, it comprises square chest type cavity, suction tude, steam outlet pipe, catalyst converter and pipeline, square chest type inside cavity is provided with multiple vertical dividing plates, and form multiple points of cavitys, suction tude is connected with a point cavity for both sides respectively with steam outlet pipe, each point of inside cavity is provided with catalyst converter, and the outlet side of catalyst converter is provided with acoustical panel; Between adjacent two points of cavitys, pass through pipeline communication; The bottom of each point of cavity is large mouth cone structure upward, and the bottom of point cavity is provided with valve.
Described suction tude stretches into a point cavity, and the sidewall that suction tude is positioned at one section of point cavity is provided with bloop.
Described suction tude is arranged at the top of point cavity, and steam outlet pipe is arranged at the below of point cavity.
The utlity model has following advantage:
1, cavity is divided into three points of cavitys, by catalysis and the noise elimination of point cavity, promote the effect of catalytic efficiency and noise elimination, catalyst converter covers the whole cross section of point cavity, make tail gas after catalyst converter, obtain sufficient catalysis, suction tude is provided with bloop, and the air outlet place of catalyst converter is provided with acoustical panel, increases the effect of noise reduction.
2, dividing the bottom of cavity is large mouth cone structure upward, particle that reaction produces precipitable with a point cavity bottom, the bottom of point cavity is provided with valve, is convenient to clear up deposit seed, has avoided the particle deposition in waste gas streams to stop up and affects reduction reaction.
3, cavity is made up of the stainless steel material of corrosion-and high-temp-resistant, ensures that cavity can bear the heat energy producing in catalytic process, extends the working life of cavity.
