Abstract
The invention discloses a carrier for a motor vehicle exhaust catalytic purifier. The carrier comprises a barrel (1) and a core (2) arranged in the barrel (1). The carrier is characterized in that the core comprises a surface plate (21) and a corrugated plate (22), wherein the surface plate and the corrugated plate are wound to form pore passages (3), and the corrugated plate comprises first waves (221) and second waves (222) which are arranged in a crossed manner, so that the pore passages are nonlinear constraint pore passages. The carrier fro the motor vehicle exhaust catalytic purifier has the advantages that the pore passages are the nonlinear constraint pore passages owing to the waves which are arranged in the crossed manner, contact area of exhaust and a catalytic coating is increased, and contact time of the exhaust and the catalytic coating is prolonged, so that catalytic reaction is sufficient, and activity and efficiency of the catalytic purifier are obviously improved.
Description
Technical field
The present invention relates to a kind of 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 by this invention provides a kind of 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 present invention adopts following technological scheme: a kind of 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 flat board and corrugated sheet, described corrugated sheet is located on the flat board, described dull and stereotyped the coiling forms helical duct, and described corrugated sheet is provided with the first ripple arranged in a crossed manner and the second ripple is divided into non-wire harness duct with helical duct.
Improved, described the first ripple and described the second ripple square crossing arrange.The area of contact of catalyst coatings on the sectional area in increase duct and then increase tail gas and the duct wall.
Improved, described the first ripple is along the circumferential setting of core body, and described the second ripple is along the axial setting of core body.So that entering from the other end from an end, tail gas flows out smoothly.
Improved, the degree of depth of described the first ripple is less than the degree of depth of described the second ripple.So that the duct is communicated with, tail gas can circulate in the duct.
Improved, some the first ripples equidistantly be arranged in parallel, and some the second ripples equidistantly be arranged in parallel.Some ducts size shape is consistent, the tail gas catalytic purification effect uniformity that circulates in each duct.
Improved, described corrugated sheet is connected on the dull and stereotyped side wall surface by soldering.Prolonged the time that tail gas contacts with catalyst coatings.
Improved, described core body is connected by soldering with the cylindrical shell jointing place.Prevent core body play in cylindrical shell.
Beneficial effect:
After adopting technique scheme, this invent a kind of catalytic purifier for motor vehicle exhaust with carrier by ripple arranged in a crossed manner so that the non-wire harness in duct, increased the area of contact of tail gas and catalyst coatings, prolonged the time of contact of tail gas and catalyst coatings, make the more abundant of catalytic reaction generation, significantly improved activity and the efficient of catalytic cleaner.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further:
Fig. 1 is cross-sectional structure schematic diagram of the present invention;
Fig. 2 is the structural representation of corrugated sheet among Fig. 1.
Embodiment
As depicted in figs. 1 and 2, a kind of catalytic purifier for motor vehicle exhaust carrier, comprise cylindrical shell 1 and be located at the interior core body 2 of cylindrical shell, described core body comprises flat board 21 and corrugated sheet 22, described corrugated sheet is located on the flat board, described dull and stereotyped the coiling forms helical duct 3, and described corrugated sheet is provided with the first ripple 221 arranged in a crossed manner and the second ripple 222 is divided into non-wire harness duct with helical duct.Described corrugated sheet is by two-way compacting forms to flat board.Described the first ripple and described the second ripple square crossing arrange, described the first ripple is along the circumferential setting of core body, described the second ripple is along the axial setting of core body, the degree of depth of described the first ripple is less than the degree of depth of described the second ripple, some the first ripples equidistantly be arranged in parallel, and some the second ripples equidistantly be arranged in parallel.Described corrugated sheet is connected on the dull and stereotyped side wall surface by soldering, and described core body is connected by soldering with the cylindrical shell jointing place.
Except above preferred embodiment, the present invention also has other mode of execution, and those skilled in the art can make according to the present invention various changes and distortion, only otherwise break away from spirit of the present invention, all should belong to the defined scope of claims of the present invention.
