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, there is catalysis and noise elimination function, from the package structure of square chest type catalytic muffler in the market, all adopt the encapsulation scheme of import larger vector, caused packaging cost to occupy height not.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of square chest type catalytic muffler, by a point cavity body structure, promotes the performance of catalysis and noise elimination, to solve the above-mentioned multinomial defect causing in prior art.
For achieving the above object, the utility model provides following technological scheme: a kind of square chest type catalytic muffler, comprise the cavity that is built-in with catalyst converter, cavity is provided with suction tude and steam outlet pipe, and described cavity is divided into point cavity of 3 sealings by dividing plate, and suction tude is connected with a point cavity for both sides respectively with steam outlet pipe, divide in cavity and be provided with catalyst converter, divide between cavity and be connected by pipeline, catalyst converter covers the whole cross section of point cavity, and catalyst converter outlet port is provided with acoustical panel.
Preferably, described suction tude setting and the top of dividing cavity, described steam outlet pipe is arranged on the below of point cavity.
Preferably, 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.
Preferably, the bottom of described point of cavity is large mouth cone structure upward, and the bottom of point cavity is provided with valve.
Preferably, described cavity is made up of the stainless steel material of corrosion-and high-temp-resistant.
Adopt the beneficial effect of above technological scheme to be: the square chest type catalytic muffler of this model utility structure, 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, the air outlet place of catalyst converter is provided with acoustical panel, increase the effect of noise reduction, the bottom of dividing cavity is large mouth cone structure upward, particle that reaction produces precipitable with a point cavity bottom, divide the bottom of cavity to be provided with valve, be convenient to clear up deposit seed, avoid the particle deposition in waste gas streams to stop up and affected reduction reaction, cavity is made up of the stainless steel material of corrosion-and high-temp-resistant, ensure that cavity can bear the heat energy producing in catalytic process, extend the working life of cavity.
