The foldable structure provided by the utility model ensures that tail gas inside the casing can flow more flexibly, transverse and longitudinal flowing are achieved, the oxidized time of the tail gas is extended, and the oxidation efficiency is improved.
Description
Technical field
The utility model relates to the retraction type catalytic converter, and it is that a kind of tail gas that can make has mobilization dynamic on horizontal and vertical in catalytic converter, and the catalytic converter of higher oxygen efficiency is arranged, and belongs to the catalytic converter field.
Background technique
Along with the harshness day by day of environmental protection requirement, increasing automobile has been installed exhaust gas catalytic converter and oxygen sensor device.It is arranged in engine exhaust pipe, pass through redox reaction, three kinds of waste gas harmful substance CO, HC of motor discharge and NOx are converted into to harmless water, carbon dioxide and nitrogen, therefore be referred to as again ternary (effect) catalytic converter, but the transformation efficiency of traditional catalytic converter is not high, the flow through path of tail gas in catalytic converter is shorter, and flow velocity is very fast, and the harmful gas in tail gas has little time by abundant oxidation.
The model utility content
In order to solve the problem of above-mentioned existence, the utility model discloses the retraction type catalytic converter, this catalytic converter can be cushioned vehicle exhaust in time, tail gas can evenly spread apart in catalytic converter, more sufficient area of contact is arranged, avoid tail gas fully not oxidized, just be discharged in air.
The retraction type catalytic converter, comprise housing, it is characterized in that the cross section of described housing is for circular, be provided with the catalytic carrier element in housing, the catalytic carrier element is the roll film of mind-set outside coiled coil therefrom, scribbles oxidation catalyst on roll film, is provided with aperture on roll film.
The shortest diameter of described housing cross section is longest diameter 1/2.
One end of described housing is suction port, and the other end is air outlet, and the diameter of suction port equates with the maximum diameter of housing, and the diameter of air outlet equates with the minimum diameter of housing.
Be provided with filter screen on described air outlet, be coated with oxidation catalyst on filter screen.
Be provided with the filter plate vertical with the catalytic carrier element in the housing of described diameter of the housing biggest place, spray oxidation catalyst on filter plate.
Described filter plate vertically is applied in the gap of catalytic carrier element.
The utility model, vehicle exhaust enters catalytic converter from suction port, in catalytic converter, tail gas fully contacts with the catalytic carrier element, the abundant oxidized catalyst oxidation of energy, and constantly the cycle changes the cross-sectional diameter of housing, make tail gas in catalytic converter, in a lateral direction, can constantly flow, make tail gas more fully oxidized.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Fig. 2 be the A-A of Fig. 1 to view,
Fig. 3 be the B of Fig. 1 to view,
Reference numerals list: 1-housing, 2-air outlet, 3-suction port, 4-filter screen, 5-catalytic carrier element.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.Should understand following embodiment and only for the utility model is described, be not used in restriction scope of the present utility model.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, word " interior " and " outward " refer to respectively towards or away from the direction of particular elements geometrical center.
Visible by reference to the accompanying drawings, this retraction type catalytic converter, comprise housing 1, the cross section of described housing 1 is circular, is provided with catalytic carrier element 5 in housing 1, and catalytic carrier element 5 be the roll film of coiled coil outside mind-set therefrom, scribble oxidation catalyst on roll film, be provided with aperture on roll film.The utility model, housing 1 is that catalytic carrier element 5 covers with the interval that ambient air separates, make ambient air can not enter in housing 1, cross section is circular, it is the tail gas circulation area fully improved in housing 1, avoid stopping up, the variation in the diameter cycle of housing 1 cross section, make housing 1 form the folding structure in cycle, tail gas has more stable flowing in housing 1 on vertical and horizontal, catalytic carrier element 5 can increase contacting of catalyzer and tail gas greatly, improves oxygenation efficiency, and aperture facilitates tail gas to flow in the horizontal.
The shortest diameter of described housing 1 cross section is longest diameter 1/2, not only makes the tail gas can lateral flow, also avoids tail gas mobile flow velocity in the vertical.
One end of described housing 1 is suction port 3, and the other end is air outlet 2, and the diameter of suction port 3 equates with the maximum diameter of housing 1, and the diameter of air outlet 2 equates with the minimum diameter of housing 1.Suction port 3 diameters are larger, do not affect the smooth discharge of tail gas, and in air outlet, 2 diameters are less, improve the speed that tail gas stream is gone out, and avoid in air outlet 2 in air, to form and reflux.
Be provided with filter screen 4 on described air outlet 2, on filter screen 4, be coated with oxidation catalyst.There is no oxidized complete nitrogen oxide and oxycarbide in oxidized tail gas.
Be provided with the filter plate vertical with catalytic carrier element 5 in the housing 1 of described housing 1 diameter biggest place, spray oxidation catalyst on filter plate; Described filter plate vertically is applied in the gap of catalytic carrier element 5.Make tail gas in the process mobile towards air outlet, also can, by mobile catalytic oxidation, improve oxidation efficiency.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-mentioned technological means, also comprises the technological scheme be comprised of above technical characteristics combination in any.
