The metal honeycomb carrier structure used for the catalyst has the advantages of being firm, transformation of the surface plates and the corrugated plates is compatible under the working condition, compression resistance and bearing capacity is greatly improved, service life is long, meanwhile, a superficial area is increased, and the transformation rate is improved.
Description
Technical field
The present invention relates to a kind of catalyzer metal beehive carrier structure.
Background technique
Catalyst carrier is the critical component of catalyst converter, and its material is divided into pottery and metal two classes.Ceramic monolith is for metallic carrier, and its geometric area is little, and thermal conductivity is low, and thermal capacity is high, and shock resistance is poor, under equal efficient, uses the converter volume of ceramic monolith large, takes up room many.Metallic carrier has good electric conductivity, can realize electric preheating, the high back pressure in the time of fundamentally can solving the ceramic monolith exhaust and when cold start-up discharging conversion ratio extremely low defect, therefore the metallic carrier performance is better than ceramic monolith.
Common metallic carrier structure as shown in fig. 1, in outer sleeve 1, is provided with surface plate 3 and corrugated sheet 2 overlapping rolling and the honeycomb hole 4 that forms in the market, and catalyst carrier is in honeycomb hole 4.The shape of common corrugated sheet 2 is sinusoidal waveform, and its crest section and trough section are against respectively on adjacent two-layer surface plate 3.Each honeycomb hole 4 is surrounded by corrugated sheet 2 and surface plate 3, under operating temperature, corrugated sheet 2 and surface plate 3 can be out of shape by expanded by heating, but adopt the honeycomb hole of this waveform configuration, because the amount of deformation of corrugated sheet and surface plate is different, particularly different along the amount of deformation on circumferential direction, produce alternating stress, on one side that certain that causes honeycomb hole is out of shape is excessive, be easy to surpass its fatigue limit, cause cracking destruction, have a strong impact on working life.
Summary of the invention
The purpose of this invention is to provide and a kind ofly improve that honeycomb hole is stressed, the catalyzer of life-saving metal beehive carrier structure.
Technical solution of the present invention is: a kind of catalyzer metal beehive carrier structure, comprise by surface plate and the overlapping a plurality of honeycomb holes that surround that roll of corrugated sheet, and be provided with at least one flex point section on the described corrugated sheet of a side of described honeycomb hole.
Be provided with at least one flex point section on the corrugated sheet of a side of honeycomb hole, changed its shape, can effectively reduce corrugated sheet amount of deformation along circumferential direction when being heated, itself and the surface plate amount of deformation on circumferential direction is complementary, reduce thermal stress, improved the resistance to compression bearing capacity of carrier, extended working life, can also increase simultaneously the internal surface area of corrugated sheet, improve the conversion ratio of catalyzer.
Be provided with at least one flex point section on the described corrugated sheet of another relative side of described honeycomb hole.Flex point section is set respectively on the relative dual-side of honeycomb hole, can further coordinates the amount of deformation of corrugated sheet, so that surface plate and the corrugated sheet of applicable unlike material roll the honeycomb porous structure that forms.
Flex point section on the relative dual-side of described honeycomb hole is symmetrical arranged.The symmetrical flex point section of arranging on the relative dual-side of honeycomb hole can make the distortion of corrugated sheet more even, more controlled.
Advantage of the present invention is: the metal beehive carrier sound construction, and the compatibility of deformation of working state lower plane plate and corrugated sheet, the resistance to compression bearing capacity promotes greatly, and long service life has increased surface area simultaneously, has improved conversion ratio.
