Description
Technical field
The present invention relates to the ultra-fine preparation method containing oxygen inorfil bundle of a kind of hydrocarbon resins strengthening, for the preparation of the carrier material of the particle preprocessor of DOC, POC, CSF and similar DPF, also can be applied to the carrier material of SCR postprocessor.
Background technology
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 gasoline engine, the discharge capacity due to the particulate of diesel engine is 20 ~ 70 times of gasoline engine, and therefore, the application of diesel engine is subject to certain restrictions;
In the pollutant of automobile, mainly comprise NOX and PM; Discharge quantity of particulate matter all in air, the discharge capacity of motor vehicle occupies the 3rd of total amount, every year close to 600,000 tons;
Motor vehicle granular material discharged in, being mainly distributed in particle size is in the scope of 2.5 ~ 10 μm, and referred to as PM2.5 ~ PM10, this kind of particle to greatly, becomes the emphasis of current motor vehicle exhaust emission purified treatment to the harm of the mankind; Beijing state 5 standard come into effect recently, the discharge quantity of not only stricter restriction PM2.5 ~ PM10, and define the restriction to all particle number PN; Visible, the following post-processing technology for the treatment of PM2.5 ~ PM10 is more general with equipment;
At present, both at home and abroad for the treatment of PM2.5 ~ PM10 is all adopt DPF preprocessor, this technology monopolize by CORNING and NGK company, the factor that expensive price will become restriction and promotes the use of at home, the following problem that also can face more market and use;
DPF is the diesel particulates preprocessor that filter core made by a kind of foamed ceramics, has not through hole that filter area is increased, wall distributed the micropore differed in size in filter core, micropore diameter 8 ~ 16 μm, porosity 40% ~ 50%, channel width 2 ~ 3mm, wall thickness 0.30 ~ 0.45mm; Fresh DPF exemplar can reach 95% to PM treatment effect; After the DPF particulate accumulation used is a certain amount of, rear spray diesel combustion heating, the particulate be deposited on filter core is burnt, and realize regeneration, theoretically, DPF can be permanently effective;
The mechanism of particle filtering is the combination compressing effect, fuel factor and electrical effect; Utilize carrier retaining and colliding particle, and the acting in conjunction of the diffusion of particle self and gravitational settling realizes purification removing; Wherein, compression effect refers to the slightly subflexuose micropore on matrix, and be equivalent to the effect of filter cake and filter bed, being dammed when PM particle is forced through these micropores collects, and reaches filter effect, forms certain thickness filter bed most critical here; Fuel factor refers to and can be understood as isochoric heat effect, and under the particulate of a nanoparticle size is in higher temperature conditions, thermal vibration frequency is accelerated, and the track of Brownian movement is more tortuous, thus, adds the possibility be trapped; And the friction that electrical effect refers in motion between thing and between particle and wall makes it surface with electric charge, though it may have passed macropore above also likely by means of electrostatic interaction retain by the slightly large-sized hole of the next one and elimination;
How to select new material and technique, the macrostructure of the design filter of science and microstructure are important problems;
Possess comparatively filtration efficiency and lower exhaust resistance to the basic demand of particulate filter; The performance of particulate filter affects by many factors such as filter structure parameter and flow parameters, 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 determine 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 effectively can improve the filter efficiency of particulate filter and reduce gas-flow resistance, but are subject to the restriction of the installing space of vehicle; Standard specifies that the maximum airflow resistance of the particulate filter of vehicle generally will control at below 10kPa, and in addition, particulate filter also must meet the features such as mechanical strength, thermal stress impact and manufacturing technique are easy; Above-mentioned characteristic must rely on carrier new material to realize;
The patent No. is the diesel motor exhaust carbon soot particles catcher/filter patent of CN201020287676.0, in drum housing, be provided with the stainless (steel) wire be closely wound around, described stainless (steel) wire is provided with backfin and belling, but the through duct possessed 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, from the effusion of center afterbody, what play a role in filtering is glass, and this structure exists the problem of air flow method inequality, in addition, the cycle pulse exhaust airstream of automobile engine will dispel glass to be torn, and the life-span is short, loses 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 traditional structure; The patent No. is the diesel particulate filter patent of CN200410055292.5, is the DPF Carboround of the wall-flow type that a kind of FBC of employing additive is assisted, and contains the oxide of vanadium, the oxide of tungsten and metal palladium catalyst and 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 honeycomb of part stream.Honeycomb thermal capacity gradually changes from arrival end to the port of export; The patent No. is the exhaust gas particle filter of CN200810215253.5 and the process patent of manufacture exhaust gas particle filter, is a kind of exhaust gas particle filter adopting metallic foam support completely; The patent No. is the diesel soot particulate filter device cylinder patent of CN201080028039.4, a kind of diesel soot particulate filter device of woven wire winding of the wall-flow type of many according to certain way arrangement; The patent No. is the diesel exhaust gas purifying filter patent of CN03804171.5, that filling has the particulate ceramic porous body of tridimensional network and forms in filter container, the average grain diameter of described particulate ceramic porous body is 4.0 ~ 20mm, described particulate ceramic porous body has a large amount of artificial pore of being formed therein and to be connected with each other logical intercommunicating pore with adjacent pore, is exposed to the surface of described porous body air cap described in some.
The technical scheme adopted for realizing process particulate matter is not unique, and therefore, the automobile-used particulate matter filter device that exploitation is different from DPF is a technology having very much challenge;
For the PM2.5 ~ PM10 particle disposal standard-required facing the future stricter, some traditional filtering materials, such as, woven wire and metal sintering felt cannot be competent at.
