The sine wave type metal honeycomb carrier comprises a shell and a core body which is arranged on the shell and is mainly and technically characterized in that according to the core body, thin and flat steel strips and steel strips with sine waves are overlapped and coiled to form sine wave honeycomb holes. The sine wave type metal honeycomb carrier is large in surface area and high in catalytic efficiency, advantages are provided for load of the catalyst, and the discharge capacity of the motor vehicle can be reduced obviously; the sine wave type metal honeycomb carrier has a special sine wave honeycomb hole structure, so that the wind resistance of air discharge is low, the output power of an engine can be improved, and energy consumption can be reduced; the size and the density of the honeycomb holes of the honeycomb carrier are controlled by controlling the amplitude magnitude of the sine wave strips and the number of the flat strips and the wave strips which form the core body, an optimum carrier can be provided for motor vehicles under different working conditions, and the sine wave type metal honeycomb carrier is used flexibly and conveniently; and by the sine waves, the back pressure can be reduced while the tail gas can remain for enough time so as to meet the purification requirement, and a good purification effect is achieved.
Description
Technical field
The utility model relates to the metal beehive carrier that is used for load machine motor-car exhaust gas catalytic conversion.
Background technology
Along with China's rapid economic development; The urban automobile recoverable amount also rises violently thereupon; Thereby the pollution problem that automotive emission caused also highlights day by day; Therefore the demand to motor-vehicle tail-gas purifying device certainly will grow with each passing day, and in exhaust gas cleaner, catalyst carrier has remarkable influence to its purification efficiency.In motor-vehicle tail-gas purifying device, catalyst carrier mainly contains pottery and metal two big classes at present, and metallic carrier is with respect to ceramic monolith; Geometrical surface is big; Good heat conductivity, thermal capacity is low, and anti-seismic performance is good; Shared volume is little under equal efficient, so the general effect of metallic carrier is better than ceramic monolith.
Comparatively common metallic carrier mainly contains metal mesh shaped and cellular two types of core bodys at present; And the metal mesh shaped core body is out-of-date in air communication, is prone to cause back pressure to increase inner the formation than big turbulent flow of core body, and engine operating condition is changed; Efficient reduces, and durability is short relatively poor service life.Through-type, angle type honeycomb substrate that another kind is to use sheet metal to make, through-type makes that the time of contact of tail gas and catalyst short because the flow resistance that gas passes through is too small within it, purification efficiency is lower; And in the type honeycomb ceramics of angle, make efficiency of engine have reduction to a certain degree because there is bigger turbulent phenomenon.
Summary of the invention
The purpose of the utility model is to overcome the shortcoming of above-mentioned prior art; Provide a kind of geometric jacquard patterning unit surface utilization rate high; Air-flow within it portion's time of staying suitable, mechanical endurance is good, the low motor vehicle tail-gas purifying of back pressure is with the sinusoidal waveform metal beehive carrier of catalyst.
The utility model is realized through following technical scheme:
Motor vehicle tail-gas purifying comprises housing 1 with the sinusoidal waveform metal beehive carrier of catalyst, and is installed in the core body 2 in the housing, and described core body is by Boping steel band 3 and the band sine bellows steel band 4 overlapping sinusoidal waveform bee-holes that roll into.
Described core body can by one deck Boping steel band at least and at least one deck sine bellows steel band roll after overlapping and form.
Described core body can and lack one band sine bellows steel band than the quantity of Boping steel band by the Boping steel band and roll and form.
Be connected through soldering between described Boping steel band and the sine bellows steel band.
Described core body sinusoidal waveform bee-hole size is to be controlled by sinusoidal wave amplitude and Boping steel band quantity.
Described sinusoidal wave amplitude is between 1.0-3.0mm; Described Boping steel band quantity is that 4-10 opens.
Described case material is the heat-resistance stainless steel of thickness 1.00～1.50mm.
Described core material is that thickness is the heat-resistance stainless steel of 0.05～0.20mm.
Compared with prior art, the utlity model has following beneficial effect:
The surface area of the utility model is big, and for the load of catalyst provides advantage, catalytic efficiency is high, can significantly reduce the blowdown flow rate of motor vehicle; And, make the exhaust resistance of bringing about the desired sensation little because of it has the special bee-hole structure of sinusoidal waveform, and can improve the power output of engine, cut down the consumption of energy; The sinusoidal pattern ripple can let tail gas stop time enough when reducing back pressure, to satisfy the needs of catalytic purification, good purification; The utility model can be through control sine bellows band the amplitude size and form the flat rubber belting of core body, the quantity of corrugated ribbon controls the bee-hole size and the density of honeycomb substrate, best carrier is provided can for the motor vehicle of different operating modes, and is flexible and convenient to use.
