Description
Technical field
The utility model relates to the post-processing technology field of diesel engine, specifically a kind of diesel particulate filter of fast changeable filter core.
Background technique
Two large main trend of vehicular engine development are energy-conservation and environmental protection.The characteristics such as diesel engine has thermal efficiency height, fuel economy is good, low speed torque is large, long service life and maintenance cost are low, and the fuel consumption of diesel engine and CO
2Discharge amount lacks 30% than the petrol engine of Same Efficieney, and this makes diesel engine become a few days ago comparatively ripe energy-conservation first-selected power, is widely used in the every field of national economy.
But diesel engine maximum problem in application is that its particulate matter discharging is many, along with the increasingly increase of environmental protection problem significance, reduces the important directions that Harmful Emissions of Diesel Engine becomes diesel engine development in the world today.Contain a large amount of particulates in the diesel exhaust gas, its particle diameter is little, lightweight, can be suspended in for a long time in the atmosphere, is sucked and be deposited in the alveolar by human body easily, health is caused great harm, cause that easily breathing problem, asthma, cancer etc. are to the great disease of human health damage; Also can exert an influence to environment, such as atmospheric pollution, water pollution, acid rain, global warming etc.; Simultaneously, Atmospheric Grains also is one of institute of environmental administration problems of concern on the impact of visibility always, although the aerosol in the particulate of diesel emission only accounts for sub-fraction, but on the impact of the optical property of atmosphere even can reach 99%, the extinction coefficient of carbon soot particles is 2-3 times of transparent grain, and the carbon soot particles of lesser amt just can cause some local visibility to reduce half.Therefore, the discharging of diesel engine has caused the generally attention of various countries, and has formulated the rules of corresponding control motor vehicle emission, and strict Abgasgesetz is so that the Exhaust Control for Diesel Engine technology becomes the emphasis of diesel engine industry research.
The control technique of diesel emission is to improve gradually along with improving of Abgasgesetz, in order to reach emission regulation demands, the purification diesel engine particulate matter is to solve the major issue that diesel engine pollutes, existing tail gas particle catcher, filtering material has ceramic fiber, foam ceramic filter body, wall-flow honeycomb ceramic filter etc., and these material for core are mostly expensive.Although there be the advantage high to the arresting efficiency of particle in existing filter, because captive particulate matter is gathered in the catcher, increase along with particulate matter in the catcher, the exhaust back pressure of motor can progressively rise, and to a certain degree rear engine oil consumption meeting increases, and efficient can reduce.
The model utility content
The shortcomings such as efficient is low when processing the particle of diesel emission, engine consumption large, filter core dismounting difficulty that be to solve prior art, the utility model provide a kind of simple in structure, cost is low, the diesel particulate filter of the fast changeable filter core of easy accessibility.
The utility model is to solve the problems of the technologies described above the technological scheme that adopts to be: a kind of diesel particulate filter of fast changeable filter core, mainly by upper outlet pipe, lower outlet pipe, circular cylindrical shell and the filter core that is located in the circular cylindrical shell form, the inner peripheral surface spacing of the outer peripheral surface of described filter core and circular cylindrical shell is 1mm, filter core is the integrative-structure that circular stainless (steel) wire forms by metallic cylinder and cross section, stainless (steel) wire is perpendicular to the filter core medial axis, and closely overlay in the metallic cylinder layer by layer along the medial axis direction, stainless (steel) wire is divided into three kind specifications to lower exhaust pipe end according to pore size from upper exhaust pipe end, 200 orders successively, 160 orders, 120 orders, the thickness that stacks of all size stainless (steel) wire all accounts for 1/3rd of metallic cylinder axial length; Be equipped with the draw-in groove of clamping circular cylindrical shell on the flange plate of the flange plate of described upper outlet pipe and lower outlet pipe, evenly be provided with respectively four hangers on the circumferencial direction of flange plate and flange plate, be equipped with spring carrier arm on four hangers of flange plate.
Described metallic cylinder connects an end uncovered of upper outlet pipe, and the other end is welded with cross-shape frame, is used for fixedly stainless (steel) wire.
Draw-in groove place on the described upper and lower outlet pipe flange plate also is provided with pad, prevents filter gas leakage when work.
Hangers on the described upper and lower outlet pipe flange plate is symmetrical in the vertical axis direction setting of circular cylindrical shell.
Described spring carrier arm can rotate by the circumferencial direction of hangers on lower outlet pipe flange plate, and the hangers of being convenient to spring carrier arm and upper outlet pipe is used, and clamps filter core; Simultaneously, be convenient to dismounting and the maintenance of filter core.
The inner peripheral surface spacing 1mm of the outer peripheral surface of described filter core and circular cylindrical shell has guaranteed to be convenient to more renew cartridge when cold state, and when engine running, because the effect of expanded by heating, the spacing of 1mm will be cancelled, and guarantees the normal operation of filter.
The draw-in groove of the utility model flange plate setting plays positioning action to circular cylindrical shell, the axial and activity surplus radially of restriction circular cylindrical shell, and the pad at draw-in groove place plays seal action to filter core, prevents the leakage of tail gas.
The beneficial effects of the utility model:
(1) during engine operation, the particulate matter in the tail gas is filtered out by the stainless (steel) wire that the filter core interior-layer layer closely stacks, and the filter cartridge construction compactness is closely knit, long service life, and after the part stainless (steel) wire damages, can in time change;
(2) for Automobile Design, the radial dimension of tail-gas after treatment apparatus is strict, and is insensitive to the axial dimension requirement, and the utility model can suitably increase the quantity of stainless (steel) wire to improve filter efficiency;
(3) pore size of stainless (steel) wire is different in the utility model filter core, the aperture that begins stainless (steel) wire from upper exhaust pipe end is reduced successively by 200 orders, 160 orders, 120 orders, aperture from big to small can effectively reduce the discharging of particle in the tail gas, avoided simultaneously mutually piling up the problem that causes the filter life cycle short because of the particle of various diameters, improved filter efficiency; And this structure can reduce the pressure loss of tail gas in filter, has reduced the exhaust back pressure of motor, and the power of motor is improved;
(4) spring carrier arm that arranges on the hangers can be realized the fast assembling-disassembling of filter core, renew cartridge more, prevents that filter core is aging, loses efficacy, and has improved filter efficiency, and has been convenient to maintenance, maintenance and the replacing of filter, reduces cost.
