The utility model discloses the distribution of well pore on the body reaches 750 / square inch to wall thickness between two adjacent porees is no longer than 40 mu m, and specific surface has obtained effectual expansion, has improved catalysis efficiency, has promoted the catalytic effect of catalyst, and the wave design is adopted in the pore, has prolonged the time of tail gas through catalyst surface, further promotion catalytic effect, and reduced the emergence that appears the stifled grey condition pore in.
Description
Technical field
The utility model relates to a kind of catalyst carrier, is specifically related to a kind of carrier for ceramic honeycomb catalyst.
Background technology
The industrialized development of automobile industry, the tail gas pollution brought is also day by day serious, Europe comes into effect the control criterion of exhaust emissions already, present exhaust emission standard is European IV discharge standard, China has also started to pay attention to motor vehicle exhaust emission problem in recent years, just coming into effect European III exhaust emission standard, namely discharging standards III.
Ceramic catalyst carrier is the core component in automobile exhaust gas purifying installation, in order to absorption tail gas cleaning catalyst with purifying automobile tail gas, catalyst carrier can make the cleaning catalyst made have suitable shape, size and mechanical strength, to meet the operation requirements of industrial reactor; Ceramic catalyst carrier can make active component disperse in its surface, obtains higher specific area, improves the catalytic efficiency of unit mass active component.Modal is so far the carrier for ceramic honeycomb catalyst of 200 holes/inches square, 400 holes/inches square, 600 holes/inches square, but the hole count that the current manufacturer production of China goes out is more than the carrier for ceramic honeycomb catalyst of 600 holes/inches square, most wall thickness is not less than 1.7mm, and the catalytic effect of catalyst is not good.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, provides a kind of specific area large and can extend catalysis time, thus promoting the carrier for ceramic honeycomb catalyst of catalytic effect.
Technical scheme: for achieving the above object, the utility model provides a kind of carrier for ceramic honeycomb catalyst, comprise columniform body and run through some ducts of body, described duct is evenly distributed on body and distributed number on body is 750/square inch, and the wall thickness between described two adjacent ducts is no more than 40 μm.
Preferably, described wall thickness is 40 μm.
Preferably, the cross section in described duct is circular.
Preferably, the inwall in described duct is provided with stainless steel layer, and stainless steel has high-corrosion resistance, can prevent the inwall in duct from being corroded by tail gas, thus extend the service life of catalyst carrier.
Preferably, the shape in described duct is waveform, and corrugated design extends the time of tail gas by catalyst surface, thus improves catalytic effect, and decreases in duct the generation of the situation occurring stifled ash.
Beneficial effect: the utility model compared with prior art, the distribution of duct on body reaches 750/square inch, and the wall thickness between adjacent two ducts is no more than 40 μm, specific area obtains effective expansion, improves catalytic efficiency, improves the catalytic effect of catalyst, duct adopts undulated design, extend the time of tail gas by catalyst surface, further improve catalytic effect, and decrease in duct the generation of the situation occurring stifled ash.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
As shown in Figure 1, Figure 2 and Figure 3, the utility model provides a kind of carrier for ceramic honeycomb catalyst, comprise columniform body 1 and run through some ducts 2 of body 1, described duct 2 is evenly distributed on body 1 and distributed number on body 1 is 750/square inch, wall thickness 21 between described two adjacent ducts 2 is 40 μm, the shape in described duct 2 is waveform, and the cross section in described duct 2 is circular, and the inwall in described duct 2 is provided with stainless steel layer 22.
Ceramic catalyst carrier specific area (specific area refers to the gross area size that unit mass material has), the size of porosity, the shape in duct all can have influence on the catalytic effect of catalyst to vehicle exhaust, porosity is larger, specific area is larger, then gas-flow resistance is less, the result of use for catalyst of ceramic catalyst carrier is better, in the utility model, the distributed number of duct 2 on body 1 is 750/square inch, relative to prior art, the density in duct 2 increases, the specific area of ceramic catalyst carrier obtains expansion, wall thickness 21 between two adjacent in addition ducts 2 is no more than 40 μm, ultra-thin wall thickness width is far smaller than the wall thickness width of prior art, thus expand the cross section gross area in duct 2, effectively raise the catalytic effect of catalyst.
In the utility model, the shape in duct 2 is waveform, extend the time of staying of tail gas in duct, thus add the catalysis time of catalyst to tail gas, further improve catalytic effect, and decrease in duct 2 generation of the situation occurring stifled ash, the inwall in duct 2 is provided with stainless steel layer 22 in addition, and stainless steel has high-corrosion resistance, can prevent the inwall in duct 2 from being corroded by tail gas, thus extend the service life of catalyst carrier.
