Technical field
the utility model relates to automobile catalytic device field, relate more specifically to a kind of can the fast disassembly type ternary catalyzing unit of disassemble or assemble fast.
Background technique
ternary catalyzing unit, is mounted in most important outer purifier in automobile exhaust system, and the harmful gases such as CO, HC and NOx that vehicle exhaust can be discharged by it change harmless carbon dioxide, water and nitrogen into by oxidation and reduction.When the vehicle exhaust of high temperature is by purification plant, purifying agent in ternary catalyzing unit will strengthen the activity of CO, HC and NOx tri-kinds of gases, impel it to carry out certain oxidationreduction chemical reaction, wherein CO is at high temperature oxidized into colourless, nontoxic carbon dioxide; HC compound is at high temperature oxidized to water (H
2
and carbon dioxide O); NOx is reduced into nitrogen and oxygen.Three kinds of harmful gases become innocuous gas, and vehicle exhaust is purified.
the carrier body of ternary catalyzing unit is one piece of porous ceramic film material, is arranged in the middle of special outlet pipe.Claim it to be carrier, be because itself does not participate in catalytic reaction, but be covered with the noble metals such as one deck platinum, rhodium, palladium above, they can become HC, the CO in waste gas into water and CO
2
, NOx is resolved into nitrogen and oxygen simultaneously.HC, CO are toxic gases, and too much suction can lead causing death, and NOx directly can cause the generation of photochemical smog.
at present because the attention degree of country to environmental protection aspect is more and more higher, add that the practical problems such as oil product on the market and vehicle condition affect, cause the increasing number of replacing ternary catalyzing unit, under existing situation, substitute mode has following three kinds:
1, genuine ternary catalyzing unit (Costco Wholesale is high, and car owner not easily accepts) is changed;
2, secondary factory ternary catalyzing unit (on market, product mixes, and three-without-product too many car owner distrust |) is changed;
3, universal three-element catalytic (changed with the mode of welding by cutting, require higher to welding technique) is changed.
these problems make vehicle when changing ternary catalyzing unit above, or need to bear larger cost and risk, or waste time and energy and difficult quality guarantee.Thus, market is badly in need of a kind of cost not high, and the ternary catalyzing unit of quick disassemble or assemble can be realized.
