Abstract
The utility model belongs to the technical field of the three-element catalytic convert for purifying the motor vehicle exhaust, relating to a honeycomb metal carrier. A core body is formed by rolling a thin-flat special stainless steel belt and a wave plate of a special stainless steel, and a heating electrode is added between the core body and the housing, while an electrode connecting pole realizes connection with the heating electrode by passing through a mix housing made by mixing a metal and a pottery. The utility model has the advantages that the pottery part of the mix housing plays an insulation role, while the stainless steel housing with a large area realizes a quick heating function as an electrode; besides, as the carrier greatly shortens the starting burning time of the catalyst after electrified, the utility model improves the catalytic convert efficiency of the three-element catalyst.
Description
Technical field: the utility model belongs to motor vehicle tail-gas purifying with three-element catalytic transformation technology field, relates to a kind of honeycomb metal carrier, can significantly improve catalytic conversion efficiency.
Background technique: in the purifying vehicle exhaust gas system, catalyst carrier is the critical component of catalytic converter, and its material is pottery and metal two classes.China's utility model patent (02202495.6) discloses a kind of " honeycomb metal carrier ", and this carrier is made up of housing and core body.Core body is by overlapping the rolling into of special stainless steel corrugated sheet with vertical little line and aperture.Diameter rolls less than the employing involute form of 50mm, and diameter rolls greater than the method for the employing diplopore concentric of 50mm.Because this honeycomb metal carrier can't be realized electric heating, it is long that catalytic converter will reach the ignition operating temperature time, cause catalytic conversion extremely low, especially can't resolve Motor Vehicle and when cold start-up and engine warm-up process, discharge the extremely low defect of conversion ratio, so can't satisfy emission standard more strict the 3rd, the quadravalence section.
The content of model utility: technical problem to be solved in the utility model is, a kind of honeycomb metal carrier of the heating of switching on is provided, make the catalyzer of three-way catalytic converter reach initiation temperature at short notice, significantly improve catalytic conversion, to adapt to the emission standard of strictness the 3rd, quadravalence section more.
The technical solution of the utility model is: a kind of honeycomb metal carrier, the corrugated sheet that comprises the special stainless steel that Boping special stainless steel steel band and one deck are thin rolls the core body that forms, add heating electrode at core body with between by metal and the ceramic mixing housing that is mixed and made into, the electrode pitman passes housing and links to each other with heating electrode.
The utility model can also be further perfect by following steps: the metal of mixed housing is the heat-resistance stainless steel of 1.0mm～1.5mm, and the thick of pottery is 2.0mm, and metalwork is in the lining, and ceramic segment outside.Each heating electrode account for whole metallic carrier less than 1/2, greater than 1/4 part, be corresponding two.The form that adopts arc welding or screw thread that is connected of mixing housing metal film part and electric heating pitman; The form that adopts sintering that is connected that it mixes ceramic shell with metal film, the electrical heating rod of housing makes electrical heating rod, metal film become as a whole with ceramic shell.
The beneficial effect of model utility: the utility model advantage compared with prior art: the ceramic segment that mixes housing plays the effect of insulation, and stainless steel large size housing can play the rapid heating function as electrode.Can shorten the catalyzer light-off time greatly after the carrier energising heating, thereby improve the catalytic conversion efficiency of ternary catalyzing unit.
Description of drawings: the utility model has 3 width of cloth accompanying drawings, and Fig. 1 is a most preferred embodiment, also can make the accompanying drawing of specification digest.
Fig. 1, be profile schematic representation of the present utility model;
Fig. 2, be another kind of embodiment's schematic representation of the present utility model;
Fig. 3, be core body method for coiling schematic representation of the present utility model.
Embodiment: most preferred embodiment of the present utility model is described further below in conjunction with accompanying drawing:
Embodiment: honeycomb metal carrier of the present utility model is made up of inner core and housing, its most preferred embodiment is as shown in Figure 1: core body is by Boping special stainless steel steel band 1 and thin special stainless steel corrugated sheet 2 overlapping rolling into, the form that core body rolls must become the diplopore concentric, gapped each other, its gap is an insulated channel 7.Heating electrode 6 is arranged between core body and housing, each heating electrode account for whole metallic carrier less than 1/2, greater than 1/4 part, be corresponding two, between two heating electrodes 6 certain clearance is arranged.Electrode pitman 4 passes mixing housing 3 and links to each other with heating electrode 6.Core material is to be made by the special stainless steel of 0.03mm～0.08mm; Mixed housing is to adopt the form of sintering to be mixed and made into by the pottery of the heat-resistance stainless steel metal of 1.0mm～1.5mm and 2.0mm, and metalwork is in the lining, and ceramic segment outside.The form that adopts arc welding or screw thread that is connected of mixing housing metal film part and electric heating pitman; The form that adopts sintering that is connected of its ceramic shell and metal film, electrical heating rod makes electrical heating rod, metal film become as a whole with ceramic shell.
Another embodiment of the present utility model adds a metal shell body 5 in the outside of mixing housing 3 as shown in Figure 2, its frame be made as heat-resistance stainless steel, conveniently be welded to connect with other three-way catalytic converter.
As shown in Figure 3, honeycomb metal carrier of the present utility model, the making of its core body must adopt the method for diplopore concentric to roll.
