Abstract
The utility model relates to a profiled POC metal carrier postprocessor with buffer gap at the outlet of three substrates. The profiled POC metal carrier postprocessor is characterized in that the carrier consists of foamed metal biscuits, and biscuits consisting of a single-layer mesh and Fe-Cr-Al metal meshes; the foamed metal biscuits and the biscuits are stacked alternately; the foamed metal biscuits (type A carrier) are distributed at the inlet and the outlet of the metal carrier; a buffer gap formed of the foamed metal biscuits is arranged at the outlet end; an oxidative catalyst coatingis applied on the foamed metal biscuits (type A carrier), the metal mesh biscuits (type B carrier) and the single-layered mesh; and the top end of the foamed metal biscuits (type A carrier) on both sides of the buffer gap and at the inlet and the outlet is fixed on a casing through a metal retaining ring by welding. The profiled POC metal carrier postprocessor has high mechanical strength, and isapplicable to onboard POC postprocessor for reducing the smoke density of exhaust of engines by 39% to 61%. The profiled POC metal carrier postprocessor has no back pressure, and low cost, which is equivalent to 1/4 to 1/5 the price of the import products with the similar performance.
Description
Technical field:
The utility model relates to the special-shaped POC metallic carrier preprocessor that three kinds of matrix outlets have the buffer gap, is applied to the motor car engine industry, has satisfied the environmental protection standard requirement of Europe more than 4.
Background technique:
Harmful components in the automobile engine to exhaust mainly are PM, NOX, HC and CO etc.In 2～3 years, low emission level engine has become people's arguement, has been concerned about even has thirsted for an ideal of realization in the past.
The 2007 emission regulation demands automakers of American National Environmental Protection Agency (EPA) reduce particle (PM) and the two kinds of main pollutants of nitrogen oxide (NOX) in the vehicle exhaust simultaneously.This needs suitable skill, and what shortcut addresses this problem does not have to walk.By traditional method, reduce a kind of pollution and certainly will cause another kind of increase of polluting.As if the automaker be absorbed in predicament.
Under the pressure of Abgasgesetz, diesel engine for automobile just constantly carries out technology upgrading and improvement on the one hand, on the other hand, selects appropriate post-processing technology strategy and equipment, and for example, Europe 4 or Europe 5 emission standards are satisfied in reprocessing measures such as SCR, DPF, DOC, POC.
The essence of SCR preprocessor technology is to utilize urea at high temperature to decomposite NH
3, as the NH of reducing agent
3React under the comprehensive function of catalyzer and temperature with the NOX in the engine exhaust, generate nontoxic N under the desirable operating mode
2And H
2O, thus reach the purpose of purification.But the complex structure of SCR after-treatment system, the cost of every cover becomes the obstacle of applying at 11000 yuan～25000 yuan.
The essence of DPF preprocessor technology is to utilize a kind of special carrier, for example the honeycomb hole of import and outlet end replaces ' wall stream ' formula pottery or the Carboround after the shutoff, the filter efficiency of ' black smoke ' of PM one class that fresh DPF preprocessor exemplar is discharged diesel-oil vehicle is the highest can to reach 90%, new car dispatches from the factory to detect and can reach Europe 4 or Europe 5 emission standards fully, but, costing an arm and a leg of this ceramic DPF carrier, can't be homemade, all monopolized in the world wide by ' NGK ' house journal of ' Corning ' company of the U.S. and Japan, not only the cost of every cover is at 7000 yuan～12000 yuan, and the easiest obstruction was lost efficacy, and became the obstacle of applying.
The essence of DOC preprocessor technology is the three-way catalytic converter (TWC) that is similar to the gasoline passenger car, is used for removing CO and HC in the tail gas, and carrier and catalyst technology comparative maturity all can domesticize, and price is low, the efficient height.But after being applied to diesel-oil vehicle, because the main object of its main processing is PM, only 10～30%, therefore, efficient is low, becomes the obstacle of applying to the removal efficient of PM.
The essence of POC preprocessor technology is earlier PM ' filtration ' or ' holding back ' get off, under the effect of catalyzer, carry out oxidation then, main component SOF partial oxygen among the PM is changed into CO2 and H2O, the PM particle size is reduced, eliminate the factor of its toxicity and harm, therefore, solved the essential problem that PM exceeds standard.The POC preprocessor can reach 50～80% to the treatment effeciency of PM, and blocked rate of fault is also well below DPF.Therefore, POC is the focus of foreign study, and is wherein, the most representative with Ecocat company.
The essence of POC preprocessor is advanced person's the carrier and the combination of catalyst technology.Wherein, carrier is the most key, not only influences performance, also influences cost and life-span.
The POC of Ecocat company carrier is its patented technology, and its essence is the metal honeycomb plate of structure uniqueness and the assemblying body of ultrafine metal fibers weaving felt.But cost an arm and a leg, homemade diesel-oil vehicle can not adopt in enormous quantities.
The POC carrier becomes POC preprocessor key in application.Some utilize some that the ultra thin high temperature resistant corrosion resistant plate makes ' Cellular board with and combination ', and for example, the patent No. is ' ternary cleaner metallic carrier ' patent of ' 02241118.6 '; The patent No. is ' corrugated ribbon and the metallic carrier thereof of Motor Vehicle ternary catalyst purifier metallic carrier ' patent of ' 200720088652.0 '; The patent No. is ' exhaust gas purifying metal carrier, use laminate exhaust gas purifying filter ' patent of ' 200810091662.9 '; The patent No. is ' a kind of method for making automobile tail gas three-element catalytic device with metal carrier ' patent of ' 200610114608.2 '; The patent No. is ' manufacture method of exhaust gas purifying metal carrier, exhaust gas purifying metal carrier and exhaust emission control filter ' patent of ' 200480036580.4 '; The patent No. is ' manufacture method of metallic carrier and metallic carrier ' patent of ' 200710003694.4 '; The patent No. is ' metallic carrier of motor vehicle vent gas purification catalysis agent ' patent of ' 99201749.1 '; The patent No. is ' honeycomb metal carrier ' patent of ' 00268303.2 '; The patent No. is ' metallic carrier of the outer ternary catalyst purifier of machine ' patent of ' 00243739.2 '; The patent No. is ' metallic carrier that is used for toxic emission control ' patent of ' 02202495.6 '; The patent No. is ' metallic carrier of new ceramics processing ' patent of ' 200410022788.2 '; The patent No. is ' metallic carrier for catalyst ' patent of ' 98125354.7 '; The patent No. is ' 03208434.X's ' ' honeycomb metal carrier ' patent; The patent No. is ' a kind of catalyst metal carrier with alumina layer ' patent of ' 99101110.4 '; The patent No. is ' metallic carrier that is used for internal combustion engine exhaust system ' patent of ' 98119279.3 '; The patent No. is ' 00100560.X's ' ' metal carrier for purifying waste gas ' patent; The patent No. is ' metal carrier catalyst that is used for waste-gas cleaning ' patent of ' 01111387.1 ' or the like, because the mass transfer of gas and the passage of heat transfer are through or are equal to perforation, therefore, bad to the treatment effect of PM, can't be applicable to the POC after-treatment device.
Some patents adopt wire cross to be woven into the wire netting on plane, these net sheets are stacked together again, and for example the patent No. is ' netted ceramic monolith ' patent of ' 98248772.X '; The patent No. is ' netted ceramic monolith ' patent of ' 99253757.6 '; The patent No. is ' Cellulated wiremesh carrier of catalyzing and reducing nitrogen oxides ' patent of ' 200710010357.8 '; The patent No. is ' a kind of Cellulated wiremesh carrier with aluminum oxide coating layer and preparation method thereof ' patent of ' 200710010359.7 '; The patent No. is ' method of covering aluminum oxide coating on honeycomb shaped wire mesh carrier ' patent of ' 200810011365.9 '; The patent No. is ' Cellulated wiremesh carrier that is used for purifying exhaust air ' patent of ' 200810011366.3 '; The patent No. is ' 200420094705.6 ' ' area load nano-TiO
