Abstract
The utility model discloses a carrier for a catalytic purifier for motor vehicle exhaust. The carrier comprises a barrel (1) and a core (2) arranged in the barrel. The carrier is characterized in that the core (2) comprises a plurality of parallel first plates (21) and a plurality of parallel second plates (22), the first plates and the second plates are arranged in a crossed manner and form rhombic channels (3), the exhaust flows through the rhombic channels (3), and pits (4) are arranged on side walls of the first plates and side walls of the second plates. The carrier for the catalytic purifier for the motor vehicle exhaust has the advantages that the crossed plates form the rhombic channels, the pits are arranged on side walls of the rhombic channels, accordingly, the carrier is simple in processing, the contact time of catalytic coatings with the exhaust can be effectively prolonged, the contact area between the catalytic coatings and the exhaust can be effectively increased, and the work efficiency of the catalytic purifier is obviously improved.
Description
Technical field
The utility model relates to the catalytic purifier for motor vehicle exhaust carrier.
Background technique
Motor-vehicle tail-gas is huge to the mankind and environmental hazard, has become one of main source of pollution of atmosphere.Catalytic conversion technique is the most effectively mode of present motor-vehicle tail-gas control, and the core of this technology is catalytic cleaner.The chief component of catalytic cleaner is carrier and catalyst coatings, by applying the catalytic purification that active material is realized motor-vehicle tail-gas at carrier.
As one of key components of catalytic cleaner, the material of carrier mainly contains two kinds on pottery and metal.Metallic carrier is thin because of its wall, percent opening is high, thermal conductivity is high, can effectively reduce exhaust resistance, improves the purification efficiency of catalyst coatings and prolongs working life of catalytic cleaner.In recent years, metallic carrier has obtained using more widely gradually.Metallic carrier is comprised of shell and core body, and the flat board that its core body is made of metal usually and corrugated sheet are reeled and made.Wherein, the corrugated sheet in the metallic carrier mostly is the single linear ripple, and in use catalyst coatings and air-flow are short time of contact, and area of contact is little, is difficult to realize that the efficient catalytic of catalyst coatings transforms.
Summary of the invention
Problem to be solved in the utility model provides the catalytic purifier for motor vehicle exhaust carrier, can effectively increase time of contact and the area of contact of catalyst coatings and tail gas, significantly improves the working efficiency of catalytic cleaner.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme: the catalytic purifier for motor vehicle exhaust carrier, comprise cylindrical shell and be located at the interior core body of cylindrical shell, described core body comprises some the first parallel plate bodys and some the second parallel plate bodys, described the first plate body and described the second plate body are arranged in a crossed manner and form the diamond passages that flows through for air-flow, are equipped with depression on the sidewall of described the first plate body and described the second plate body.
Improved, described depression is located at the first plate body and the second plate body and intersects on the diamond passages sidewall that is divided into.
Improved, described depression is evenly distributed on the sidewall of diamond passages.
Improved, described depression is circular or square or long hole shape or waveform or taper.
Improved, the acute angle of the cross section of described diamond passages is made as 60 °.
Improved, some the first parallel plate body spaced sets, some the second parallel plate body spaced sets.So that diamond passages is evenly distributed in the cylindrical shell, and each channel sized shape is consistent, thus from the tail gas that each diamond passages flows through can purify totally, to purify clean level even.
Improved, described the first plate body is connected by soldering with described the second plate body infall.Guarantee that the core body internal structure can the deformation effect catalyticing purifying effect.
Improved, described core body is connected by soldering with described cylindrical shell jointing place.So that core body can be in cylindrical shell play.
Beneficial effect:
After adopting technique scheme, this model utility catalytic purifier for motor vehicle exhaust forms diamond passages and at the diamond passages sidewall depression is set by the plate body that intersects with carrier, processing is simple, can effectively increase time of contact and the area of contact of catalyst coatings and tail gas, significantly improve the working efficiency of catalytic cleaner.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
