Embodiment
Referring to Fig. 1-3, the present invention relates to a kind of square acid-proof ceramics honeycomb substrate, and it includes cylindrical body, the column
The section of body is in quadrangle, by the first end to end arc-shaped edges 1, the second arc-shaped edges 2, the circular arc of three-arc side 3 and the 4th
Side 11 forms, and first arc-shaped edges 1, the second arc-shaped edges 2, the junction of the arc-shaped edges 11 of three-arc side 3 and the 4th are using circle
Angle transition, the cylindrical body are densely covered with stomata 4 in the axial direction, and one end of the stomata 4 is opening 9, and the other end is provided with
Closure face 5, the closure face 5 and the arranged for interval of opening 9, next door 6 is provided between the two neighboring stomata 4, is opened on next door 6
There is the micropore 7 in cellular arrangement, catalyst coat 10 is coated with next door 6.
Wherein, the hole count of stomata 4 is 600 holes/square inch, and the thickness in next door 6 is 0.13 ~ 0.14mm.
The ceramic honey comb surface is coated with acid-proof coating, and this acid-proof coating is mainly matched by following raw materials by weight portion
It is made：13 parts of quartz sand, 12 parts of petroleum coke, 9 parts of wood chip, 8 parts of sodium chloride, 1 part of titanium dioxide, 13 parts of ethanol, 30 parts of water.
The preparation method of the acid-proof coating, is comprised the steps of：
（1）Quartz sand, petroleum coke and wood chip are pulverized, powder diameter is 400 mesh；
（2）By step（1）In powder and sodium chloride powder the input high temperature resistance furnace of acquisition, radiant heating, temperature is maintained at

Operation principle：The present invention is fabricated to honeycomb ceramic carrier using cordierite, and is built in diesel engine vent gas purification
In device, the waste gas with black smoke particle of diesel engine discharge enters from the opening 9 of stomata 4, because stomata 4 is opened at one end
Mouthfuls 9, and be then closure face 5 in the other end, therefore waste gas can be by the next door 6 with micropore 7, then opening from adjacent air holes 4
Mouth 9 is discharged, and because the diameter of black smoke particle is big compared with micropore 7, therefore the black smoke particle in waste gas will catch next door 6 by filtering
On, air-flow then passes through from micropore 7.
Active rare earth of the catalyst coat 10 containing noble metal, Main Ingredients and Appearance have Pt, Pd, Rh, Al2O3、Ce、La、
Zr, Cu, Mn, the waste gas of diesel combustion（The predominantly pernicious gas such as CO, HC, NOx）During through micropore 7, coat on next door 6
Catalyst coat 10 will strengthen CO, HC, NOxThe activity of three kinds of gas, it is promoted to carry out certain oxidationreduction chemistry anti-
Should, wherein CO is oxidized to colourless nontoxic carbon dioxide at high temperature, and HC compounds resolve into water at high temperature（H2O）With
Carbon dioxide, NOxIt is reduced into nitrogen and oxygen.
When diesel exhaust gas temperature reaches 375 degrees Celsius, in the presence of catalyst coat 10, the black smoke on next door 6
Particle can progressively burn and aoxidize, and the purifying rate of black smoke particle about reaches more than 85%, when reaction temperature reaches 500 degrees Celsius
When catalyst and black smoke particle reaction fall so as to completely burned（Catalysis burning）, now the purifying rate of black smoke particle up to 90% with
On.
