Abstract
The utility model relates to technical filed of three-element catalytic conversion devices for purification of motor vehicle exhaust, in particular to a metal honeycomb carrier for catalytic purification of motor vehicle exhaust. The technical problem that the design of the prior art is not reasonable enough and the like are resolved. The metal honeycomb carrier for the catalytic purification of the motor vehicle exhaust comprises a round cylinder casing and a core arranged in the casing and is characterized in that the core is provided with a plurality of evenly distributed parallel plates, and a bending plate in a square-wave shape is arranged between two adjacent plates. Compared with the prior art, the a metal honeycomb carrier for the catalytic purification of the motor vehicle exhaust has the advantages of being reasonable in design, simple in structure, easy to process and fabricate, low in fabrication cost, stable and reliable in working performance and high in mechanical strength.
Description
Technical field
The utility model relates to motor vehicle tail-gas purifying with three-element catalytic reforming unit technical field, especially relates to a kind of catalytic purification of motor vehicle tail gas and uses metal beehive carrier.
Background technique
In the purifying vehicle exhaust gas system, catalyst carrier is the critical component of catalytic converter, and its material is pottery and two types on metal.Because ceramic monolith is little with respect to the metallic carrier geometric area, back pressure is high, thermal conductivity is low, thermal capacity is high, vibration resistance is poor; Under equal efficient; The converter volume is big, it is big to take up room; And metallic carrier has good electrical conductivity one and can realize electric preheating, the high back pressure when fundamentally having solved the ceramic monolith exhaust and when cold start-up the extremely low defect of discharging conversion ratio, so metallic carrier is superior to ceramic monolith.Existing in the market metallic carrier generally adopts dull and stereotyped rolling after overlapping with corrugated sheet to form, and gas is shorter in the internal stops time: the geometric jacquard patterning unit surface utilization ratio is low, causes catalytic conversion low.
For this reason, people have carried out long-term exploration, have proposed various solutions.For example, the Chinese patent document discloses a kind of metallic carrier [application number: CN99201749.1] of motor vehicle vent gas purification catalysis agent, and it is characterized in that: metallic carrier is a sheet, on tinsel, is provided with the micropore of the band projection burr with certain density.Such scheme has improved conversion ratio to a certain extent.Technical problems such as but it is reasonable inadequately still to exist design, and the manufacturing cost is high, and structural strength is lower, and working life is short.
Summary of the invention
The purpose of the utility model is to the problems referred to above, provides a kind of reasonable in design, simple in structure, and mechanical strength is high, and the catalytic purification of motor vehicle tail gas of long service life is used metal beehive carrier.
For achieving the above object; The utility model has adopted following technical proposal: this catalytic purification of motor vehicle tail gas is used metal beehive carrier; Comprise being housing cylindraceous, in housing, be provided with core body, it is characterized in that; Described core body comprises some being parallel to each other and equally distributed plate body, is provided with the folded plate that bending is square waveform between the two adjacent plate bodys.
Above-mentioned catalytic purification of motor vehicle tail gas with metal beehive carrier in, described folded plate thickness is 0.05-0.1mm; The thickness of described plate body is 0.1-0.2mm.
Above-mentioned catalytic purification of motor vehicle tail gas with metal beehive carrier in, described housing is processed by stainless steel and the thickness of housing is 1.0-1.5mm.
Compared with prior art, this catalytic purification of motor vehicle tail gas is with the advantage of metal beehive carrier: reasonable in design, simple in structure, be easy to manufacturing, and cost of production is lower, stable and reliable working performance, and mechanical strength is high.
Description of drawings
Fig. 1 is the structural representation that the utility model provides.
Among the figure, housing 1, core body 2, plate body 21, folded plate 22.
Embodiment
As shown in Figure 1, this catalytic purification of motor vehicle tail gas comprises with metal beehive carrier and is housing 1 cylindraceous, in housing 1, is provided with core body 2.Core body 2 comprises some being parallel to each other and equally distributed plate body 21, is provided with the folded plate 22 that bending is square waveform between the two adjacent plate bodys 21.In the present embodiment, folded plate 22 thickness are 0.05-0.1mm; The thickness of plate body 21 is 0.1-0.2mm.Housing 1 is processed by stainless steel and the thickness of housing 1 is 1.0-1.5mm.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
