Description
Technical field
This utility model relates to a kind of carbamide cleaner, especially, is used in automobile SCR aftertreatment system
A kind of carbamide cleaner.
Background technology
Along with the continuous increase of quantity possessed by automobile so that the automobile impact on environment, increasingly by people
Attention.Being mainly the tail gas of motor vehicle emission by public concern to pollute for environment, this is the most just
Make countries in the world more and more tighter to the regulation of motor vehicle exhaust emission.
SCR technology (SCR) is for a process skill of NOx in exhaust gas from diesel vehicle discharge
Art, i.e. under the effect of catalyst, sprays into reducing agent ammonia or carbamide, the NOx in tail gas in exhaustor
It is reduced into N2And H2O, reaches the most energy-conservation, but also the purpose that reduces discharging.Wherein gas drive formula SCR urea injection system,
Owing to its reliability is high, easy to maintenance, low cost, approved by increasing user.
As the carbamide cleaner used in gas drive formula SCR urea injection system, in it is in urea tank,
It is connected with carbamide outlet tube.Urea liquid in described urea tank is after described carbamide cleaner filters, logical
The metering valve crossing described carbamide outlet tube entrance hybrid chamber measures, and enters back into urea nozzle and sprays,
The effect of described carbamide cleaner is to ensure that the cleannes of metering valve and urea nozzle.
Referring to shown in Fig. 4, existing carbamide cleaner, including filtering seat upper cover 42, filtering seat lower cover 44
And filter element 46.Wherein in the middle of described filtering seat upper cover 42, it is provided with urea inlet 420, carbamide outlet tube 50
It is connected on described filtering seat upper cover 42, and connects with described urea inlet 420.Urine in described urea tank
Cellulose solution is in described urea inlet 420 is pressed into described carbamide outlet tube 50, to follow-up metering valve
With the urea liquid that urea nozzle provides cleaning.
Further, refer to shown in Fig. 5, owing to described urea inlet 420 is positioned at described filtering seat upper cover
42, it requires that urea liquid liquid level is higher than the carbamide minimum liquid level line 48 shown in figure, this means that urine
In element tank, the urea liquid at described minimum liquid level line less than 48 is unserviceable.According to as described in urea tank
Height be about 400mm, described carbamide cleaner height is about 60mm, so, just has about 60mm
The urea liquid of left and right height is unserviceable, say, that the utilization of described urea tank internal memory urine storage element
Rate is actual only has about 85%.
It addition, use time must also consider vehicle go up a slope time, on the impact of urea level in described urea tank.
Refer to shown in Fig. 6.Vehicle is when flat road surface travels, when urea level is higher than minimum liquid level line 48,
System can normally work.But when vehicle driving up, urea liquid the most also can incline in described urea tank
Tiltedly, now urea liquid minimum level will be positioned at urea inlet less than 420, it is impossible to exports for described carbamide
Pipe 50 is supplied urea solution.It is contemplated that to impact during vehicle driving up, the urea liquid in described urea tank
Effective rate of utilization can be less than 85%.
Further, even if urea liquid is at described carbamide minimum liquid level line more than 48, but run at vehicle
During can jolt unavoidably, urea liquid also can produce bubble therewith rocking, and thus can cause entry into urine
Element outlet tube 50 in addition to urea liquid, also can be mixed with air, so owing to being mingled with bubble, will make
The actual urea amount obtaining metering valve ejection reduces, thus influences whether the transformation efficiency of NOx.In this situation
Under, OBD likely can produce warning.
And consider that carbamide outlet tube 50 port of export (is positioned on urea tank temperature-liquid level sensor flange, in figure
Do not show) it is to be connected with post-injection pipeline with quick connector, if quick connector connects due to fortuitous event pine
Moving or disconnect, urea liquid can spray urea tank, may cause hurting sb.'s feelings under pressure.
Finally, the filter element that described carbamide cleaner uses is usually nylon material, and filter efficiency is relatively low, to carefully
Little particulate matter, filter efficiency is the lowest.
Therefore, necessary develop a kind of novel automobile SCR aftertreatment system carbamide cleaner,
Overcome defect of the prior art.
Utility model content
The purpose of this utility model is to provide a kind of automobile SCR aftertreatment system carbamide cleaner, its urine
The relative efficiency utilization rate of the urea liquid in element tank is higher, can reach more than 98%, thus reduce user and add
The frequency of note carbamide.
For realizing above-mentioned utility model purpose, this utility model adopts the technical scheme that
A kind of automobile SCR aftertreatment system carbamide cleaner, it includes filtering seat upper cover, filtering seat lower cover
And filter element, wherein said filtering seat upper cover extends to described filtering seat lower cover direction has carbamide to go out sap cavity.
Described carbamide goes out the upper end external carbamide outlet tube of sap cavity, and its lower end is provided with urea inlet hole.
Further, in different embodiments, under wherein said filtering seat, cap upper surface concave downward is formed
The urea inlet hole having liquid storage cylinder, described carbamide to go out sap cavity extend in described liquid storage cylinder.
Further, in different embodiments, wherein said carbamide goes out the diameter in urea inlet hole of sap cavity
It is 1～1.5mm.
Further, in different embodiments, wherein said filter element includes the filter element of fold filter paper form.
Compared to prior art, a kind of automobile SCR aftertreatment system carbamide filtering that this utility model relates to
Device, it arranges liquid storage cylinder in its filtering seat lower cover, and reduces height and its opening of its urea inlet simultaneously
Size, and use the filter element of fold filter paper form so that it has the advantages that
1. the effective rate of utilization making the urea liquid in its place urea tank is greatly improved, and takes off from the prior art
About 85% shown brings up to more than 98%, thus reduces user to a certain extent and fill the carbamide frequency；
2. eliminate the urea liquid actual liquid level caused when vehicle driving up due to inclination of vehicle to reduce；
3. eliminate the impact of the bubble produced in urea tank when vehicle jolts, it is ensured that the accuracy of spray of metering valve,
Thus reduce the system caused due to urea injecting quantity deficiency and report an error；
4., if quick connector loosens or disconnects, the urea liquid that can cause ejects outside urea tank, by
Going out sap cavity inlet hole diameter in carbamide and be reduced to 1～1.5mm, urea injecting quantity is limited, can greatly reduce and hurt sb.'s feelings
Risk；
5. the higher material for core of service precision so that the replacing construction of described filter element is greatly prolonged, uses the longevity
Life is up to more than 100,000 kilometers.
