Description
Technical field
A kind of ammonia filter of SSCR systems is the utility model is related to, after the tail gas of diesel-engine vehicles
Process field.
Background technology
The improvement of China's increasingly attaching importance to environmental protection engineering, especially atmosphere pollution in recent years, and motor-vehicle tail-gas is then made
One of pollution sources main into atmosphere pollution.
In all automotive emission pollution problems, although diesel vehicle proportion in all vehicles is less,
It is that pollution problem is the most serious, by taking Beijing as an example, heavy-duty diesel vehicle about 220,000, though quantity only accounts for vehicle guaranteeding organic quantity
4%, but the nitrogen oxides of its discharge（NOx）And particulate matter（PM）But the 50% and more than 90% of vehicular emission total amount is accounted for respectively.
In China, the liquid area spraying system of the exhaust gas aftertreatment system use of diesel vehicle, because this system is present
The problem of urea crystals, easily cause pipeline blockage, damage of components, and maintenance cost is higher, and now domestic diesel oil
Car installs no specification additional for liquid area, is all to decide installation in its sole discretion by driver, which results in vehicle urea brand is numerous and diverse, good
Green bristlegrass is uneven, more increases the risk of system jams.Moreover, the liquid area tank volume of present diesel vehicle is small, for length
For the vehicle of way transport, it usually needs prepare several barrels of liquid area onboards, it is inconvenient so as to the possible period of want or need.
For the SSCR systems of problem above, at present my company's invention, can effectively solve problem above, due to injection
Be gas ammonia, the problem of being not in pipeline blockage.Loading filter device in SSCR systems（Cleaner）Ammonia can be ensured
Gas purity, so as to which the control accuracy and service life problem of whole system will not be produced because of gaseous impurity.The storage of my company's production
Ammonia tank can disposably continue a journey 10000 kilometers, greatly save the time of driver, and the ammonia storage tank of my company's production is all by public affairs
Department is uniformly responsible for filling, and quality is greatly ensured.User is set not have trouble and worry.Compared to traditional liquid urine prime system
System, ammonia emitted dose can more accurately be controlled by loading the SSCR systems of cleaner, and ammonia itself is relatively inexpensive so that be used
The family expense used in everyday that continues is lower, accomplishes the profit maximization of user.
The content of the invention
The purpose of this utility model is to provide a kind of ammonia filter of SSCR systems, and it can be improved in SSCR systems
Ammonia purity, to ensure the control accuracy of whole system and service life.
What the technical solution of the utility model was realized in：A kind of ammonia filter of SSCR systems, its feature exist
In：Ammonia storage tank pressure sensor is connected with preheating rail assembly, and the outlet side of preheating rail assembly is connected with filter assembly, cleaner
Assembly is connected by pipeline with gas rail assembly, and ratio stop valve, gas are housed on the connected pipeline of the gentle rail assembly of filter assembly
Gas rail pressure sensor and temperature sensor are disposed with rail assembly, the outlet side of gas rail assembly is sprayed by pipeline and ammonia
Pipeline connects, and ammonia metering valve is housed on the pipeline between gas rail assembly and ammonia injection line, ammonia storage tank is sprayed by ammonia
Pipeline is connected with preheating the inlet end of rail assembly, and ammonia metering valve is connected by signal wire with DCU assemblies.
Good effect of the present utility model is that it can improve the ammonia purity in SSCR systems, to ensure whole system
Control accuracy and service life.
Brief description of the drawings
Fig. 1 is structure chart of the present utility model.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings：A kind of as shown in figure 1, ammonia filtering of SSCR systems
Device, it is characterised in that：Ammonia storage tank pressure sensor 8 is connected with preheating rail assembly 1, the outlet side of preheating rail assembly 1 and filtering
Device assembly 2 is connected, and filter assembly 2 is connected by pipeline with gas rail assembly 4, the connected pipe of the gentle rail assembly 4 of filter assembly 2
Ratio stop valve 3 is housed on road, gas rail pressure sensor 6 and temperature sensor 7 are disposed with gas rail assembly 4, gas rail assembly 4
Outlet side be connected by pipeline with ammonia injection line 9, be equipped with the pipeline between gas rail assembly 4 and ammonia injection line 9
Ammonia metering valve 5, ammonia storage tank 11 are connected by ammonia injection line 9 with preheating the inlet end of rail assembly 1, and ammonia metering valve 5 is logical
Signal wire is crossed to be connected with DCU assemblies 10.
Fig. 1 is refer to, Fig. 1 is the apparatus structure schematic diagram that the present invention implements ammonia filtering technique.
A kind of ammonia filtering technique of SSCR systems provided by the invention, it is electric on DCU assemblies 10 first in vehicle launch
And vehicle signal is received, and now ammonia storage tank 11 starts to build pressure, when ammonia storage tank 11 builds pressure, ammonia storage tank（11）Interior ammonia passes through ammonia
Gas jet pipeline 9 is reached in electric-control system, and what is arrived first at is preheating rail assembly 1, ammonia from preheating rail assembly 1 by, by
Directly communicated with the ammonia in ammonia storage tank 11 in ammonia now, thus now preheat ammonia pressure in rail assembly 1 with
Ammonia pressure in ammonia storage tank 11 is identical, and the ammonia storage tank pressure sensor 8 being now connected with preheating rail assembly 1 is gathered
Ammonia pressure be exactly ammonia pressure in ammonia storage tank 11, the data that ammonia storage tank pressure sensor 8 is gathered pass through bundle assembly
It is passed in DCU assemblies 10.The ammonia in preheating rail assembly 1 is being added by corresponding heater in preheating rail assembly 1
Heat.It is electric on DCU assemblies 10 when starting due to vehicle, instruction is sent, opens ratio stop valve 3, so, when in ammonia storage tank 11
When thering is the ammonia to occur, directly can be arrived by ammonia injection line 9, the filter assembly 2 of preheating rail assembly 1, ratio stop valve 3
Up in gas rail assembly 4.Gas rail pressure sensor 6 and temperature sensor 7 are all attached with gas rail assembly 4, when ammonia passes through ratio
When example stop valve 3 enters gas rail assembly 4, the data that gas rail pressure sensor 6 and temperature sensor 7 are gathered are total by wire harness
Into being passed in DCU assemblies 10.Ammonia metering valve 5 is connected with gas rail assembly 4, and ammonia reaches ammonia meter via gas rail assembly 4
Measure in valve 5, instruction is sent by DCU assemblies 10, the 5 regular unlatching of control ammonia metering valve, sprays ammonia.Ammonia is via ammonia
Metering valve 5 is ejected into ammonia injection line 9, and together arrival is handled the ammonia after above-mentioned steps make filtering with Vehicular exhaust
In device, it is sufficiently mixed within a processor with Vehicular exhaust, reaches the purpose of vent gas treatment.
When motor vehicle local environment temperature changes, the temperature data of environment temperature and gas rail assembly 1 can pass through
CAN lines are transferred in DCU assemblies 10, are judged by DCU assemblies, if start preheating rail heater to preheating rail assembly 1
Heated, by such a method, SSCR systems are adapted to various environment temperatures.
