Abstract
The utility model discloses a carrier used for metal three-unique catalytic converter. The utility model comprises baffling boards and catalyst coating boards. The catalyst coating boards are arranged betweem the baffling boards, the baffling boards are heat-resistant alloy baffling boards, the section shape of the unit space rounded by the baffling boards and the catalyst coating boards is of triangle shape. The utility model employs the characteristics of good plasticity and high intensity, the utility model can be squeezed to be a thin slice of 0.08 to 0.1 mm, the utility model is made by rolling of special process, and the geometrical shape of the section of the carrier is a faviform of haplopore triangle ray shape. Compared with the ceramic material, the air flowing resistance of the carrier is the smallest at the same area of catalytic reaction. Thereby the utility model is favor of reducing the back pressure of an engine and reducing the power loss. Because of the above characteristics of the metal material and the special geometrical shape, the utility model can improve the heat conductivity of catalyst, increase the heat stability, and prevent the catalyst from sintering and inactivating due to overheating of the wall.
Description
One, technical field
The utility model relates to a kind of catalytic cleaner carrier, relates in particular to metal ternary catalyst purifier carrier.
Two, background technique
Existing ternary catalyst purifier is generally ceramic monolith with carrier, and it is poor that ceramic monolith exists impact resistance, the shortcoming that the gas flow resistance is big.
Three, summary of the invention
The utility model provides a kind of good impact resistance and can improve the metal ternary catalyst purifier carrier that becomes gas flow characteristic.
The utility model adopts following technological scheme: metal ternary catalyst purifier carrier, form by dividing plate and catalyst-coated laminate, the catalyst-coated laminate is located between the dividing plate, dividing plate is the heat resisting alloy dividing plate, and the unitary space sectional shape that catalyst-coated laminate and dividing plate are surrounded is a triangle.
Compared with prior art, the utlity model has following advantage: 1. the utility model utilizes that heat resisting alloy plasticity is good, advantages of high strength, under existence conditions, can be pressed into 0.08～0.1 millimeter thin slice, roll with special process and to form, the geometrical shape of carrier cross section is that a plurality of single hole triangle combinations form aplysia punctata, compare with stupalith, under equal catalytic reaction area, vector gas flow resistance minimum.Therefore, reduction engine back pressure, minimizing power loss are played crucial effects.Simultaneously, because of the above-mentioned characteristic of metallic material and special geometrical shape, to the thermal conductivity of improving catalyzer, increase thermostability, prevent to play good effect because of local superheating causes the sintering of catalyst inactivation.2. the utility model is considered from now on to the raising of automobile fourth finger mark requirement and the working life of prolongation carrier, especially to reducing high temperature deactivation, chemical poisoning, sintering and factors such as obstruction and mechanical deterioration, compare with ceramic monolith, the utility model adopts the density that reduces the hole relatively, and adopt the coaxial stack combinations of 2 carriers, make the utility model when guaranteeing catalytic effect, improve gas flow characteristic, can realize that three-way catalytic converter is controlled at 2% international indicator to the negative effect of fuel consume and output power.3. the utility model on metal partion (metp) and catalyst-coated laminate at the micropore that 400 order/square inches are set, with the chemical industry paintability that improves metallic carrier with increase bond strength.Because of the plasticity of metal is good, can suppress 0.08～0.1 millimeter thin plate, the carrier porosity ratio is also improved simultaneously, this metal carrier increases by 30% than the total catalytic purification area of ceramic monolith.
