The utility model discloses a kind of double bed ternary catalyzing unit, comprise housing, be separately positioned on suction tude and the outlet pipe at housing two ends, in described housing, suction tude place is provided with reducing catalyst, described housing is provided with oxidation catalyst near outlet pipe place, air cavity is provided with in the middle of described reducing catalyst and oxidation catalyst, the housing of described air cavity is provided with air duct, and described housing is spliced by reducing catalyst, oxidation catalyst and air cavity.The utility model can be purified waste gas by two-bed catalyst bed, and quick detachable setting avoids ternary catalystic device structure and holds flimsy problem, long service life and transformation efficiency is high.
Description
Technical field
The present invention relates to automobile exhaust purification equipment technical field, particularly relate to the ternary catalyzing unit on a kind of automobile engine exhaust pipe road.
Background technique
Ternary catalyzing unit major function is discharged into air after the harmful gas of discharging after engine combustion is changed into innocuous gas, catalyzer in catalytic converter can promote the oxidation reaction of hydrocarbon and carbon monoxide, and it is changed into water vapour and carbon dioxide respectively; Reduction of nitrogen oxide is become nitrogen simultaneously, but the core body of existing ternary catalyzing unit is encapsulated in housing more and can not takes out, cause cleaning not easily, affect the working life of ternary catalyzing unit, and the carrier of existing ternary catalyzing unit is all-in-one-piece, there is certain defect, if go wrong, need whole changing, working life is low.
Model utility content
For overcoming above-mentioned deficiency, the invention provides a kind of easy to clean, long service life and the high double bed ternary catalyzing unit of transformation efficiency.
The technical solution adopted in the utility model is: a kind of double bed ternary catalyzing unit, comprise housing, be separately positioned on suction tude and the outlet pipe at housing two ends, in described housing, suction tude place is provided with reducing catalyst, described housing is provided with oxidation catalyst near outlet pipe place, air cavity is provided with in the middle of described reducing catalyst and oxidation catalyst, the housing of described air cavity is provided with air duct, and described housing is spliced by reducing catalyst, oxidation catalyst and air cavity.
As the further setting of such scheme, the skin of described housing is provided with thermal shield, is also provided with buffer layer between described housing and thermal shield.
As the further setting of such scheme, described buffer layer is ceramic seal cushion packing.
As the further setting of such scheme, the Placement of described reducing catalyst, oxidation catalyst and air cavity is for being threaded or being socketed connection.
As the further setting of such scheme, described reducing catalyst, oxidation catalyst are ceramic honeycomb material, and the shell of reducing catalyst, oxidation catalyst is made up of stainless steel.
The utility model can be purified waste gas by two-bed catalyst bed, and quick detachable setting avoids ternary catalystic device structure and holds flimsy problem, long service life and transformation efficiency is high.
