Description
Technical field
The present invention relates to a kind of lightweight catalytic converting device for being exclusively used in diesel motor, especially one
Planting effectively can be fully cleaned up the waste gas that diesel motor is discharged the device of simultaneously decarbonizing.
Background technology
Diesel oil carbon particulate cleaner (diesel particulate filter, be abbreviated as DPF)
Effect is that the waste gas of diesel vehicle burning is collected for catching and carbon particulate is filtered.When the carbon of trapping is micro-
When more than grain to a certain degree, the ECU driving computers of vehicle can carry out " filter regeneration " running,
Carbon particulate in cleaner is burnt into carbon dioxide discharge, filtering function is maintained with polishing filter.
The waste gas of diesel vehicle discharge includes what is polluted the environment in addition to containing carbon particulate, also
Nitrogen oxides (NOx), therefore existing is to be catalyzed reductor (selective catalytic
Reduction, SCR) handle nitrogen oxides, the system of the catalysis reductor be by urea via
Urea cylinder located at automobile injects burned waste gas, by red-hot exhaust gas conversion ammonification
(Ammonia, NH3), and ammonia produces chemistry also with the nitrogen oxides (NOx) in catalysis reductor
Original work are used, so as to be converted into not influenceing the nitrogen (Nitrogen) and water of natural environment.Due to foregoing
Conversion reduction diesel oil and urea ratio be usually 20: 1 (often use 20 parts of diesel oil,
Just 1 part of urea is needed), cause the consumption of urea very quick, it is necessary to which often addition could be maintained just
Often running, is bothered, and extremely expend money very much using upper.
The content of the invention

Axially one first through type ceramic element 3a and one second through type is sequentially set to make pottery in four chambers 16
Porcelain filter core 3b；One wall-flow type filter core 4 is then set in the 5th chamber 17.The CC Catalytic Converter is to be used for
The poisonous carbon monoxide 90% and hydrocarbon 85% come out from engine emissions is reduced, it is constituted into
Divide is that, using the shaping of cordierite (COERIERITE) ceramics extrusion, reprocessing is formed.Cordierite is one
Kind superior heat proof material (fusing point up to 1400 degree of C), its thermal coefficient of expansion, therefore, can close to zero
The rapid temperature difference is stood, moreover, (1200 degree of below C) its mechanical strength is on the contrary with temperature at high temperature
Rise and increase.
The through type ceramic element is to draw using the porous characteristic of cordierite ceramic to catch diesel oil
Discharged particulate contaminant is held up, each passage of filter core is opening at one end, and in the other end
Then closed, therefore, force exhaust to be passed through by porous ceramic wall.Due to cigarette ash particle compared with
The hole of ceramic wall is big, therefore will be caught by benefit on passage.When filtering element (cartridge) load is reached the limit of,
These cigarette ashes, which must be ignited burn-up (oxidation), could recover the function of filter core, the step of this soot oxidation
Suddenly referred to as " regenerate ".In order to reduce back pressure, it is to avoid the horsepower of influence engine, general recommendations is used
The ceramic element capacity that more than 2 times of engine exhaust amount is standard.
The wall-flow type filter core is to add coating oxidation catalyst (DOC) using metallic particles storage, and it is
Formed by metal corrugated plate comprising metal wire web plate winding of the multilayer with spade-type structure, reprocessing is formed
Metal honeycomb filter core.DOC (200 DEG C -450 DEG C) within the scope of appropriate temperature is continuously generated
NO2And flow into grain catcher, NO2With the carbon particle that is deposited on metal fiber felt plate appropriate
Oxidation regeneration reaction persistently occurs for (200 DEG C -450 DEG C) in temperature range, and this process is called even
Continuous passive regeneration.Grain catcher reduces the carbon particle in waste gas with DOC collective effects.
Foregoing first and second through type ceramic element 3a, 3b and wall-flow type filter core 4 are impregnated in advance
In urea liquid or ammonia solution, urea liquid or ammonia solution is set to penetrate into the through type ceramic element with being somebody's turn to do
Processing is dried again after in the pore of wall-flow type filter core, makes the through type ceramic element and the wall
Flow type filter element, which has, can be reduced to nitrogen oxides the effect of nitrogen and water.

CC Catalytic Converter 2c, then confluxes by the first through type ceramic element 3a in the 4th chamber 16 again
With the second through type ceramic element 3b, make in engine still imperfect combustion carbon particle and one totally
The black smoke waste gas such as carbonoxide, hydrocarbon, can be by the first of front end when via emission by exhaust pipe
High temperature to the 3rd CC Catalytic Converter 2a, 2b, 2c directly burns purification, and other poisonous fumes are such as
Nitrogen oxides (NOx) etc., then can be in first and second through type ceramic element 3a, 3b by rear end
Decomposition-reduction is subject into nitrogen and moisture by urea or ammonia during with wall-flow type filter core 4, to reduce to environment
Pollution.
