Abstract
The utility model relates to a particulate catcher for a diesel engine, which comprises an outer housing, a filter core arranged in the outer housing, an end cover arranged at the end of the outer housing. The outer housing and the filter core are in detachable connection. The outer housing is stainless and is provided with an air inlet and an air outlet. The filter core is made of sintered metal fibres felt and cheap filtering materials, which has a large storage volume of the particulate. The filter core can be detached and replaced, thereby avoiding block. Meanwhile, no burning regeneration method is adopted, which avoids catalyst damage and filter core burning due to incontrollable regeneration.
Description
Technical field
The utility model relates to a kind of diesel particulate trap, relates in particular to a kind of diesel particulate trap that satisfies Europe VI emission standard.
Background technique
At present, the control Engine's Harmful Emission is the effective measures of protection environment.For Diesel NOx (nitrogen oxide) and particulate emission is two big difficult points of Diesel Engine Control.Along with constantly adding of Abgasgesetz is tight, the particulate emission limit value is more and more lower.Europe IV and Europe V particulate emission limit value are 0.02g/kw.h, have only 1/5 of Europe III, and Europe VI will further reduce.For reducing the particulate emission of motor, can adopt the emission controls by improving combustion technology and use particle trap, adopt selective reduction catalyst converter (SCR) technology path both can reach the particle limit value in the Europe IV stage, adopt EGR Technology need use particle trap by the emission controls by improving combustion technology.The present particle trap of using is because after using a period of time, carbon deposit stops up filter screen, need regenerate.Regenerative process is exactly that the burning-point that adopts electrically heated way or use catalyst converter to reduce carbon granule makes carbon burning eliminate carbon distribution.More complicated, particularly catalysis type are controlled in regeneration, formulate the carbon accumulation model of catalyst converter, consider the continuous increase of ash content, and reproduction speed is also wanted strict control, so system complex costs an arm and a leg.
Constantly add tight Abgasgesetz in order to satisfy, the burning of diesel engine is more and more abundant, soot in the particulate emission is fewer and feweri, soot accounts for about 75% in the III particulate emission of Europe, Europe IV, Europe V soot proportion are 60%, and Europe VI may arrive below 40%, that is to say that the soot proportion that can remove by regeneration in the diesel engine particles discharging in the future is fewer and feweri, particle trap can not be regenerated, and uses complicated regenerative system with nonsensical.
Summary of the invention
At the problem that prior art exists, the technical problems to be solved in the utility model provides a kind of diesel particulate trap, especially a kind of need not onlinely regeneration, the diesel particulate trap that filter core can time-based maintenance.
For solving the problems of the technologies described above, technological scheme of the present invention is: a kind of diesel particulate trap, comprise shell, and be arranged on the filter core in the described shell, and the end cap that is arranged on described outer casing end, described shell removably is connected with filter core.
Described filter core diameter is more smaller than described housing diameter, and described filter core can inject in the described shell; Described end cap one end is provided with the end cap flange, described filter core one end is provided with the filter core flange, described shell one end is provided with the shell flange, and described filter core banjo clip is between described shell flange and described end cap flange, and described end cap flange, described filter core flange and described shell flange are connected by bolt.Be respectively equipped with pad between described end cap flange, described filter core flange and described shell flange, to realize sealing.
Described shell is provided with suction port and relief opening.Described filter core is the filter core that metallic fiber sintered felt is made.Described shell is the corrosion resistant plate shell.
Because the utility model adopts the structure that removably connects of shell and filter core, makes this particle trap not need online regeneration, does not have complicated reclaimer and control system, only need time-based maintenance to get final product.Filter core has bigger particle storage capacity, and is cheap.When the filter core resistance greatly to a certain degree, when adopting the method for blowback dedusting not recover, can be directly renew cartridge more.Because this system's filter core can be changed, thus there is not blocking problem, and owing to do not adopt the way of burning regeneration, so avoided the catalyst converter poison deactivation, the problem of the filter core scorification out of control of regenerating.

Fig. 2 is the fundamental diagram of a kind of diesel particulate trap of the utility model;
Fig. 3 is the assembly relation schematic representation of a kind of diesel particulate trap of the utility model.
Reference character wherein:
The 1-end cap; The 2-bolt; The 3-pad; The 4-nut; The 5-filter core; The 6-shell; 7-end cap flange; 8-filter core flange; 9-shell flange; The 10-suction port; The 11-air outlet.
Embodiment
Further specify a kind of diesel particulate trap of the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 to Figure 3, a kind of diesel particulate trap of the utility model uses corrosion resistant plate to make the spitting image of the air-strainer that uses now, is provided with suction port 10 and relief opening 11.Comprise end cap 1, filter core 5, shell 6, pad 3, shell 6 removably is connected with filter core 5.Filter core 5 left ends have a filter core flange, and filter core 5 diameters are more a little bit smaller than shell 6, can inject shell 6, and between filter core flange 8 folder shell flanges 9 and the end cap flange 7, three flanges are connected with nut 4 with bolt 2, and pad 3 is housed between flange, can realize sealing.
As shown in Figure 3, filter core adopts metallic fiber sintered felt to make, and its working principle is seen Fig. 2, and when particle trap was worked, diesel exhaust entered particle trap from suction port 10, and through the filtration of filter core, 11 discharge from the air outlet.Shell 6 and filter core 5 are removable, are convenient for changing filter core 5 or maintenance.Grey diversity is full on filter core 5, the end cap 1 of dismantling, and filter core 5 can be extracted from shell 6, thereby pulls down filter core 5, with pressurized air filter core 5 is oppositely blown off, reuses, and filter core 5 can use repeatedly repeatedly like this.After repeatedly purging, ash content Sai Detai is too many deeply, and after all blowing, more renew cartridge 5.For reducing cost, this particle trap uses cheap metallic fiber sintered felt filtering material to make filter core, and this material reusable edible.For not making and filter core is safeguarded and it is too frequent to change, the particle storage volume of filter core is bigger.In actual use, vehicle operating just must be changed a filter core for 100,000 kilometers.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
