Background technique

Oxynitrides, carbon monoxide, hydrocarbon and particulate matter in vehicle exhaust be generate haze it is important because Element, requirement of the government to motor vehicle exhaust emission are increasingly stringenter, the requirement to the service life phase of catalyst converter and particle trap It is increasingly stringenter, and the catalyst converter that uses of vehicle in use and particle trap the two devices independent of each other at present, due to urging Agent carrier and filter core, which cannot take out, to carry out specific aim maintenance and makes that maintenance effect is bad to cause service life undesirable, in addition urges Change device and particle trap due to working principle difference, structure design is also different, and previous maintenance method is different, needs separately each From maintenance, such as particle trap is the case where blocking according to measurement, to enable included electric heating system and add particle trap Burning particulate matter is discharged to achieve the purpose that dredging aperture activity recovery at gas to 600 degree or so for heat, however in particle One of component organic complex cannot be aoxidized at a temperature of 600 degree and become gas, damage can be sintered if temperature is excessively high Filter core and other component, thus for a long time or aperture can be blocked, and be equipped with measuring device and burner make it is a whole set of Particle trap is expensive；And the cleaning of ternary catalyzing unit be done work by engine combustion non-gasoline class cleaning agent generate The impurity and complex compound that the air-flow of high temperature and pressure washes out adherency, is blocked in catalyst carrier thin channel, catalyst carries at this time Body is still encapsulated in shell, however gasoline also divides the models such as 92,95, engine combustion do work non-gasoline class detergent it is inevitable Can damage engine, and fixed catalytic agent carrier relied on, by pad by compression and restorable elastic force generate it is quiet Friction value is that the business secret of each automobile factory will not disclose, and the high pressure draught of detergent generation often occurs in practice Thrust is higher than stiction, is subjected to displacement catalyst carrier in the cavity not in design position, is easy to cause carrier interior air-flow Channel blockage and carrier are broken, and reduce ternary catalyzing unit service life and even scrap.

And arrived with advances in technology some present maintenance methods can be it is identical, but due to product design structure Reason cannot maintain simultaneously, while catalyst carrier and filter core are inconvenient to take out and reinstall recovery and cause maintenance effect poor, thus Have the shortcomings that respectively individually maintenance is there are the time is long, costly, effect is poor, and maintenance effect is influence service life length Key factor.

The effect of catalyst converter is to convert nothing for oxynitrides toxic among exhaust gas, carbon monoxide, hydrocarbon Nitrogen, carbon dioxide and the water of poison, the effect of particle trap are to collect particulate matter capture among exhaust gas not to be discharged into greatly Gas, if it is possible to take out catalyst carrier and filter core, so that it may the case where observing its different parts contamination and plugging, and then take Specific aim method is avoided that secondary pollution and damage device when especially with cleaning solution, thus maintenance effect is good, therefore has Have to facilitate taking-up and the design structure for restoring catalyst carrier and filter core is installed and have to the maintenance effect of exhaust gas processing device It is significant, and maintenance effect is of great significance to the service life of automobile, and at the same time when carrying out maintenance and can save Between improve maintenance efficiency and reduce cost of upkeep, however the product used now does not have this design structure.

Summary of the invention

For the existing defect of the above-mentioned prior art, the technical problem to be solved in the present invention is to provide a kind of than existing production Product have the automobile exhaust gas processing apparatus of more long life, lower use cost.

The further technical problems to be solved of the present invention be particle trap and catalyst converter are integrated into a device, and And can be not taking-up and installation catalyst carrier and filter core can not facilitated simultaneously by press device, it simultaneously can be direct with realization The effect of catalyst carrier and filter core is maintained, and there is the automobile exhaust gas processing apparatus of energy effective protection liner.

Automobile exhaust gas processing apparatus of the invention, including dismountable case, liner, catalyst carrier and filter core, catalyst Carrier and filter core are wrapped up by liner is placed in shell inner cavity, and in catalyst carrier and filter core air inlet port or catalyst carrier Guard block is installed with filter core both ends, along narrow location contacts and the fixed catalytic at the shell inner cavity both ends of gas flow direction Agent carrier and filter core.

Since fixed catalytic agent carrier and filter core are no longer rely on the restorable elastic force of liner, that is, padding can be with normal shape State assembly does not need to compress, therefore does not need press device auxiliary assembly, or even can assemble by hand, while facilitating maintenance Created condition for good maintenance effect, at the same catalyst carrier and filter core scrap after only need to change raw catelyst carrier and filter Core is without replacing whole device, and similarly liner only needs to change new liner without replacing whole device after scrapping, and compares The prior art, that is, save the cost improves efficiency again, also extends the service life of whole device.

Further, the position 7 that narrows of automobile exhaust gas processing apparatus of the invention, shell inner cavity both ends is that shell is inside Concave layer or concave block, concave layer can be understood as the connection of continuous concave block or concave block can be understood as the segment of concave layer, concave block It is either one or more；The convex layer or convex block either formed in the outer add mode such as inner cavity casting or welding, Convex layer can be understood as continuous convex block connection or convex block can be understood as the segment of convex layer, and convex block can be one can also To be multiple；The either inner wall of shell both ends cone become narrow gradually.
