Description
Technical field
The utility model relates to a kind of mariages and mixes the carrier element that hooks volume, for the preparation of DOC, and POC, the particulate matter preprocessor of CSF and similar DPF, also can be applied to SCR preprocessor.
Background technique
For automobile industry, energy-conserving and environment-protective are common issue that Present Global faces; Although the fuel economy of diesel engine is higher than petrol engine,, because the discharge amount of the particulate of diesel engine is 20 ~ 70 times of petrol engine, therefore, the application of diesel engine is subject to certain restrictions;
In the pollutant of automobile, mainly comprise NOX and PM; All discharge quantity of particulate matter in atmosphere, the discharge amount of Motor Vehicle occupies the 3rd of total amount, approaches every year 600000 tons;
In Motor Vehicle granular material discharged, be mainly distributed in the scope that particle size is 2.5 ~ 10 μ m, referred to as PM2.5 ~ PM10, this class particle to greatly, becomes the emphasis of current motor vehicle exhaust emission purified treatment to the mankind's harm; Beijing state 5 standards that come into effect recently, the not only discharge quantity of stricter restriction PM2.5 ~ PM10, and stipulated the restriction to all particulate matter number PN; Visible, the following post-processing technology for the treatment of PM2.5 ~ PM10 and equipment are more general;
At present, all to adopt DPF preprocessor for the treatment of PM2.5 ~ PM10 both at home and abroad, this technology is monopolized by CORNING and NGK company, and expensive price is by the factor that becomes restriction and promote the use of at home, the following problem that also can face more market and use;
DPF is a kind of diesel particulates preprocessor of making filter core with foamed ceramics, has not through hole that filter area is increased, the micropore that has distributed on wall and differed in size in filter core, micropore diameter 8 ~ 16 μ m, porosity ratio 40% ~ 50%, channel width 2 ~ 3mm, wall thickness 0.30 ~ 0.45mm; Fresh DPF exemplar can reach 95% to PM treatment effect; After DPF particulate accumulation in use is a certain amount of, rear spray diesel combustion heating, burns the particulate being deposited on filter core, realizes and regenerating, and theoretically, DPF can be permanently effective;
The mechanism of particle filtering is the combination that compresses effect, thermal effect and electrical effect; Utilize carrier to the holding back and colliding of particle, and the diffusion of particle self and the acting in conjunction of gravitational settling realize purifying and remove; Wherein, compress effect and refer to the slightly subflexuose micropore on matrix, be equivalent to the effect of filter cake and filter bed, in the time that PM particle is forced through these micropores, is dammed and collect, reach filtering effect,, form certain thickness filter bed most critical here; Thermal effect refers to and can be understood as isochoric heat effect, and when the particulate of a nanoparticle size is under higher temperature conditions, thermal vibration frequency is accelerated, and the track of Brownian movement is more tortuous, thereby, increase the possibility being trapped; And electrical effect refers in motion that the friction between thing and between particulate matter and wall makes it surface with electric charge, even if may having passed through macropore above, it is also likely slightly held back and elimination in large-sized hole by the next one by means of electrostatic interaction;
Equally, for example, for the carrier of other type except DPF,, DOC, POC, CSF and SCR etc., all have the repugnance of performance boost and selling at exorbitant prices, this all shows to select new material and technique, and the macrostructure of the design vector of science and microstructure are important problems;
To possess compared with filtration efficiency and lower exhaust resistance to the basic demand of particulate filter; The performance of particulate filter is affected by the many factors such as filter structure parameter and flow parameter, and filter efficiency and exhaust resistance often exist again the trade-off relation of conflicting and mutual restriction; In particular filter structure parameter, particulate filter length, port number, channel width and wall thickness have determined length and the area of section of filter, and they not only can have influence on the overall performance of particulate filter; Increase particulate filter length and area of section and can effectively improve the filter efficiency of particulate filter and reduce gas-flow resistance, but be subject to the restriction of the installing space of vehicle; The maximum airflow resistance of the particulate filter of standard regulation vehicle generally will be controlled at below 10kPa, and in addition, particulate filter also must meet the features such as mechanical strength, thermal stress impact and manufacturing process are easy; The carrier new material that must rely on of above-mentioned characteristic is realized;
The patent No. is the diesel motor exhaust carbon soot particles catcher/filter patent of CN201020287676.0, it is the stainless (steel) wire that is provided with tight winding in drum housing, on described stainless (steel) wire, be provided with backfin and belling, still, the perforation duct possessing is unfavorable for the trapping of molecule; The patent No. is the tail gas emission filter patent of CN200920053958.1, it is a concentric tube outsourcing glass, tail gas enters from the side, overflow from center afterbody, what play a role in filtering is glass, and this structure exists the problem of air-flow skewness, in addition, the cycle pulse exhaust airstream of motor car engine will dispel glass to tear, and the life-span is short, lose efficacy very fast; The patent No. is the diesel particulate filter patent of CN200480026612.2, is the DPF ceramic monolith of the wall-flow type of conventional construction; The patent No. is the diesel particulate filter patent of CN200410055292.5, is the DPF Carboround of the auxiliary wall-flow type of a kind of FBC of employing additive, and oxide and the metal palladium catalyst of the oxide that has comprised vanadium, tungsten finally become CDPF; The patent No. is the honeycomb particulate filters patent of CN01816995.3, be a kind of along flow to axle have different wall as cellular multi-unit structure, be specifically applicable to diesel particulate filter, but it is also applicable to the cellular structure of part stream.Cellular structure thermal capacity gradually changes from entry end to outlet end; The patent No. is the exhaust gas particle filter of CN200810215253.5 and the process patent of manufacturing exhaust gas particle filter, is a kind of exhaust gas particle filter that adopts metallic foam support completely; The patent No. is the diesel engine soot particulates filter cartridge patent of CN201080028039.4, a kind of wire gaze of the wall-flow type of many of arranging according to certain way diesel engine soot particulates filter forming of reeling; The patent No. is the diesel exhaust gas purifying filter patent of CN03804171.5, that filling has the granular ceramic porous article of tridimensional network and forms in filter container, the Mean particle diameter of described granular ceramic porous article is 4.0 ~ 20mm, described granular ceramic porous article have therein a large amount of artificial pores that form and with adjacent pore logical intercommunicating pore connected with each other, described in some, pore is partly exposed to the surface of described porous body.
The technological scheme adopting for realization processing particulate matter is not unique, and therefore, the carrier of development of new is a technology that has very much challenge;
For the PM2.5 ~ PM10 particle disposal standard-required that faces the future stricter, some traditional filtering materials, for example, the net and the metal sintering felt that adopt common wire to weave, due to turbulence not, the shortcoming such as the excessive and non-refractory of the quality of per unit volume and cannot being competent at.
