Abstract
The invention discloses a hole-channel-staggering-type high-performance metal honeycomb carrier which is characterized in that the metal honeycomb carrier is made only by corrugated plates in a coiling mode, a traditional structure of flat plates and corrugated plates is broken through, holes and channels are communicated in a staggering mode, a single straight-through hole-channel structure which is not communicated is avoided, design is ingenious, so that the flat plates are avoided, only the corrugated plates are used for making an inner core, and the using number of metal foil belt materials is saved by more than 35%. The metal honeycomb carrier of the novel structure is low in air resistance and even in air flow distribution, the problems that traditional flat plate and corrugated plate metal honeycomb carrier inner core air flow distribution is not even, and the catalyst using rate is not sufficient are solved, and the metal honeycomb carrier is suitable for tail gas purifying catalyst coating of engines for various purposes.
Description
Technical field
The present invention relates generally to catalytic converter metallic carrier, relates in particular to the staggered high-performance metal honeycomb carrier in a kind of duct of only using corrugated sheet to roll into.
Background technique
Catalytic converter is a kind of Tailgas purifier of engine, carbon monoxide (CO), hydrocarbon (HC) and nitrogen oxide (NO that its energy purifying engine is discharged
x).The outside of catalytic converter is Stainless Steel Shell, and inside is metal beehive inner core.The core shape of prior art field metal beehive carrier mainly contains two kinds, concentric circle (spiral) type and S type, its core arrangement is all to be rolled and formed by some flat board+corrugated sheets, each duct of inner core is not connected, motor exhaust is when by metal beehive inner core, air-flow by mind-set surrounding diffusion profile, flow is outwards successively decreased by center, not connected pore passage structure causes the catalyzer in the middle of inner core easily aging, and the catalyst utilization of inner core surrounding is not enough, catalyst activity after durable significantly declines, and has also caused the waste of Precious Metals Resources simultaneously.
Summary of the invention
The object of this invention is to provide the staggered high-performance metal honeycomb carrier in a kind of duct, it can effectively improve traditional technological deficiencies such as flat board+corrugated sheet metal beehive carrier air-flow skewness
.
The present invention is achieved through the following technical solutions: the present invention has broken through the core arrangement of traditional flat board+corrugated sheet, only with corrugated sheet, roll into concentric circle (spiral) type or S type inner core, outer ring is fixed with metal shell, integral braze-welded formation metal beehive carrier.Described metal beehive carrier inner core only rolls and forms with corrugated sheet, and crest is that point contacts and passes through brazing with crest, and inner core duct is staggered to communicate, as catalyst-coated metal beehive carrier.
Compared with prior art, the invention has the beneficial effects as follows: can reduce carrier and catalyzer cost, can improve again transformation efficiency and the utilization ratio of catalyzer.High-performance metal honeycomb carrier provided by the invention, has solved the problems such as classic flat-plate+corrugated sheet metal beehive carrier inner core air-flow skewness, catalyst utilization deficiency.
Described housing cross section comprises that circle, ellipse, square and track type etc. are irregularly shaped.
Advantage of the present invention: structural design is ingenious, has cancelled flat board, only uses corrugated sheet to make inner core, saves inner core foil material consumption and surpasses 35%.Metal beehive carrier provided by the invention, inner core duct is staggered to communicate, and vapour lock is lower, air-flow is more evenly distributed, and has improved the utilization ratio of catalyzer.With the metal beehive carrier of inner core volume, the coated weight that can reduce catalyzer precious metal can meet the emission request of motor simultaneously.
