Embodiment
With reference to Fig. 1, it illustrates the skeleton diagram of the exemplary post-processing unit 100 for the treatment of the exhaust from internal-combustion engine 102.Post-processing unit 100 works together with cooling system 104.Post-processing unit 100 comprises diesel particulate filter (DPF) 106 and selective catalytic reduction module (being called SCR) 108, and it for processing exhaust before being discharged in the external world.DPF106 fluid is connected to SCR108 by exhaust duct 110.Exhaust duct 110 comprises mixing chamber, and it is called as exhaust duct part 112, for holding multiple fluid reducing agent injector 114.Fluid reducing agent tank, be called diesel exhaust fluid (DEF) tank 116, its fluid is connected to fluid reducing agent injector 114.DEF tank 116 holds DEF118.
Internal-combustion engine 102(is hereinafter referred to as motor 102) can be multicylinder engine, it is configured for heavy machinery, mobile device and related application.Such as, highway truck, mine truck, sliding loader, wheel loader, cat, excavator, bulldozer, wheel loader etc.In addition, the utility model is also imagined and is extended to stationary machines, such as power generation system and other motor generator set.Although the utility model proposes the layout of multi-cylinder diesel engine, do not get rid of the equivalent application of other engine type.
As a part for post-processing unit 100, one can be selected in the DPF that many places are bought from the market.DPF106 can be connected with the relief opening 120 of motor 102, and be configured for receive come from the ortho states of motor 102, untreated exhaust.After receiving, DPF106 is configured to filter or be separated coal smoke or diesel particulate matter, prevents from flowing in exhaust.
Exhaust duct part 112 is connected with DPF106 fluid by exhaust duct 110, and is arranged on DPF106(or exhaust stream A) downstream position.Exhaust duct part 112 can carry out plastotype and structure according to usually known mode, and can be configured to the filtering exhaust receiving and come from PDF106.Exhaust duct part 112 comprises mixing chamber, and it is generally used for promoting to come from the reducing agent fluid chemical field such as the filtering exhaust of DPF106 and such as DEF118.Without limitation, typical reducing agent fluid or DEF can comprise anhydrous ammonia, ammoniacal liquor or urea.
SCR108 fluid is connected to the downstream of exhaust duct part 112.SCR108 comprises catalyzer, other active catalytic components of such as titanium oxide and alkali-metal oxide, with by exhaust in conversion of nitrogen oxides for diatomic nitrogen and water.Alkali metal can include but not limited to vanadium, molybdenum and/or tungsten.As DPF106, SCR108 also can select among the known SCR unit that many places are bought from related domain.
In the configuration of general multi-cylinder and relatively large engine application, lay multiple fluid reducing agent injector 114.This is because the exhaust coming from relatively large motor may need more DEF118, to neutralize the harmful components in filtering exhaust.Correspondingly, four fluid reducing agent injectors 114 are shown here.Fluid reducing agent injector 114 change quantitatively can be conceived.Correspondingly, exhaust duct part 112 can comprise the device for containing fluid reducing agent injector 114.Although can conceive other joint method, fluid reducing agent injector 114 can be threadedly engaged with exhaust duct part 112.At one end portion, fluid reducing agent injector 114 fluid is connected to DEF tank 116 to be received the DEF118 of supply continuously by one group of Flows line.In one embodiment, each fluid reducing agent injector 114 can comprise special DEF supply line.The continuous supply of DEF can be promoted by DEF pump (not shown), and can comprise its fluid and loop back DEF tank to form other link of corresponding DEF loop (not shown).
Without limitation, fluid reducing agent injector 114 can be laid along the length direction of exhaust duct part 112.Fluid reducing agent injector 114 can be configured to regularly the DEF118 of prearranging quatity be sprayed intake and exhaust pipe section 112.DEF spray regime can be, is incorporated in exhaust duct part 112, to promote that DEF118 effectively mixes with the discharge smog entered by the spraying of DEF118 finer atomization.
Fluid reducing agent injector 114 comprises injector nozzle 124, and it extend in exhaust duct part 112.Injector nozzle 124 promotes the DEF118 of prearranging quatity to spray intake and exhaust pipe section 112, in the exhaust airstream that more particularly injection influent stream enters.But this layout causes injector nozzle 124 to bear the high temperature condition of flowing exhaust.Because these high temperature conditions can cause injector nozzle 124 fault, so often need repairing or replace.
Coolant jackets (not shown) is arranged on around fluid reducing agent injector 114 usually, more particularly, around injector nozzle 124.This kind of coolant jackets makes freezing mixture 122 flow into the coolant jackets in fluid reducing agent injector 114 from cooling system (such as cooling system 104), receives the heat from injector nozzle 124, and reduces the temperature in it.Correspondingly, each fluid reducing agent injector 114 comprises sparger coolant entrance 126 and sparger coolant outlet 128, is respectively used to inflow and the outflow of freezing mixture 122.
Therefore, in order to reduce the impact of temperature, fluid reducing agent injector 114 is operably connected to cooling system 104.Cooling system 104 comprises inside and has the coolant circuit 130 of coolant storage 132, at least one coolant pump 134, phase separation tank 136, freezing mixture anti-siphonage pipe line 138 and coolant discharge pipe line 140.
Coolant storage 132 stores freezing mixture 122, and is connected to each fluid reducing agent injector 114 via freezing mixture supply line 142 fluid.Also it is contemplated that supply line extends to the radiator (not shown) of motor 102 from coolant storage 132.Coolant pump 134 is connected to freezing mixture supply line 142, freezing mixture 122 is fed to each fluid reducing agent injector 114 from coolant storage 132 pressurization.Without limitation, coolant pump 134 can be positive-displacement pump.
Coolant manifold tank 143 can be arranged in the downstream of coolant pump 134, for receiving the pressurized coolant flowed into by freezing mixture supply line 142 from coolant storage 132.In the outlet port of coolant manifold tank 143, multiple coolant lines 145(can be set and be 4 in the disclosed embodiment).Coolant lines 145 can extend and fluid is connected to each fluid reducing agent injector 114.The fluid that this layout is convenient between coolant manifold tank 143 with fluid reducing agent injector 114 is communicated with, and sets up fluid and be communicated with between coolant storage 132 and fluid reducing agent injector 114.Therefore the independent freezing mixture stream flowing out to each fluid reducing agent injector 114 can be obtained.
The sparger coolant entrance 126 be formed on fluid reducing agent injector 114 is that freezing mixture supply line 142 is provided for carrying freezing mixture 122 to enter the entrance of fluid reducing agent injector 114.In one embodiment, the freezing mixture supply from coolant storage 132 can be provided in single pipeline, is redistributed in multiple pipeline, to arrive each fluid reducing agent injector 114 respectively.In addition, the coolant feed based on common rail freezing mixture supply system can be considered equally.
Sparger coolant outlet 128 is arranged in fluid reducing agent injector 114, corresponding to each sparger coolant entrance 126.Sparger coolant outlet 128 is convenient to freezing mixture and is flowed out/be discharged in freezing mixture anti-siphonage pipe line 138.Each sparger coolant outlet 128 fluid of fluid reducing agent injector 114 is connected to phase separation tank 136(by freezing mixture anti-siphonage pipe line 138 to be seen shown in Fig. 2 the best).
Should point out, freezing mixture anti-siphonage pipe line 138 can be relatively short pipeline (being such as shorter than about 12 inches), has relatively wide cross section (such as internal diameter is wider than about 1/4 inch).This reverse freezing mixture stream be configured to from phase separation tank 136 to fluid reducing agent injector 114 provides minimum resistance.But, in any case the numerical value proposed is without the need to being regarded as restriction herein.Further, each fluid reducing agent injector 114 can comprise the device for arranging independent anti-siphonage pipe line, as shown in the figure.
Phase separation tank 136 is arranged in the downstream of fluid reducing agent injector 114 along the direction B that can operate freezing mixture stream.Relative to fluid reducing agent injector 114, phase separation tank 136 is placed in coolant circuit 130 has higher gravitational potential energy place relatively.Make like this between thermo-motor down period, be still detained minimum freezing mixture 122 in cooling circuit (part for freezing mixture anti-siphonage pipe line 138), thus the possibility of the freezing mixture reverse flow that the pressure head of radiator is caused reaches maximum.
Therefore, by implementing substantially negligible being separated, phase separation tank 136 can only as the temporary reservoirs of freezing mixture 122.On the contrary, being separated of freezing mixture 122 can be implemented by radiator (not shown), and this can so that refrigerant evaporates.This evaporation of freezing mixture 122 causes the downstream of fluid reducing agent injector 114 to produce pressure head usually.
In addition, phase separation tank 136 fluid is connected back coolant storage 132 by coolant discharge pipe line 140, and makes coolant circuit 130 complete.Coolant discharge pipe line 140 is configured for and is back to coolant storage 132 by phase separation tank 136 with the freezing mixture crossed.In a preferred embodiment, coolant discharge pipe line 140 keeps the pressure head from radiator (not shown), and it produces negative (or backflow) pressure.This negative pressure forces the freezing mixture 122 in phase separation tank 136 between thermo-motor down period, reflux (discussing after a while).Although clearly do not illustrate, before freezing mixture 122 is transported to coolant storage 132, the pipeline extending to machine radiator from phase separation tank 136 by setting it is contemplated that freezing mixture condensation process.
Therefore, the impact of the pressure head produced by the evaporation of freezing mixture 122 is convenient to via coolant discharge pipe line 140 from radiator (not shown) to phase separation tank 136.Alternatively, radiator can be included in the regenerative system head (not shown) in coolant circuit 130, in coolant circuit 130, refrigerant evaporates and buildup of pressure can occur.
With reference to figure 2, relatively illustrate in greater detail phase separation tank 136.Phase separation tank 136 comprises multiple compartment 202.In the described embodiment, phase separation tank 136 comprises 4 compartments 202, and one of them compartment 202 corresponds to a fluid reducing agent injector 114.The number can conceiving compartment 202 is different from the possibility of disclosed number.Such as, a convection cell reducing agent injector 114 can correspond to single compartment 202.Therefore, when use four fluid reducing agent injector (114), as shown in the figure, phase separation tank 136 only can comprise two corresponding compartments 202.Other such configuration and layout can be conceived.Therefore, the structure of phase separation tank 136 limits spirit and scope of the present utility model by any way without the need to being regarded as.
Each compartment 202 comprises at least one intake section 204 and at least one exit portion 206.Each intake section 204 is communicated with at least one sparger coolant outlet 128 fluid of fluid reducing agent injector 114.In addition, each exit portion 206 fluid of phase separation tank 136 is connected to coolant discharge pipe line 140, thus is convenient to be communicated with coolant storage 132 fluid.Should point out, at least one exit portion 206 corresponds at least one intake section 204.
Industrial applicibility
During engine operation, the temperature of freezing mixture is preferably kept, and makes freezing mixture remain fluid state, has minimum evaporation.But between thermo-motor down period, coolant pump 134 is closed or quits work, stay near radiator large calorimetric but nonvolatile freezing mixture.In certain embodiments, radiator can be regenerative system head (not shown), as mentioned above.Also other radiator can be conceived, particularly still quite hot between thermo-motor down period radiator.The heat produced causes freezing mixture 122 to evaporate usually, thus produces relatively little but obvious pressure head in the downstream of coolant circuit 130.The freezing mixture of gasification remains on the direction (direction C) contrary with common downstream workflow by coolant discharge pipe line 140.In fact, the freezing mixture 144 of gasification enters phase separation tank 136, causes producing negative suction head in phase separation tank 136.
This pressure head forces the freezing mixture 122(in phase separation tank 136 for liquid usually, and has lower temperature) oppositely flow into each fluid reducing agent injector 114 through freezing mixture anti-siphonage pipe line 138.This phenomenon provides the cooling of expectation for fluid reducing agent injector 114, and more specifically, the injector nozzle 124 for fluid reducing agent injector 114 provides the cooling of expectation, prevents them from breaking down and is out of shape.Thus the negative effect of heat can be avoided.
When using the phase separation tank 136 above fluid reducing agent injector 114 staggered relatively, can avoid as providing enough pressure heads to obtain relatively a large amount of evaporative fluid.This is because gravity adds pressure head, liquid coolant is easy to from phase separation tank 136 incoming fluid reducing agent injector 114, thus causes injector nozzle 124 temperature in relative short time to decline about 30-40 degree Celsius.
Below describe thermo-motor and shut down rear other phenomenon contingent.Once coolant pump 134 stops freezing mixture supply, in fluid reducing agent injector 114, remaining freezing mixture 122 is evaporated and is risen by freezing mixture anti-siphonage pipe line 138 and arrive phase separation tank 136.This process forces the freezing mixture 122 of condensation in phase separation tank 136 to be back to freezing mixture anti-siphonage pipe line 138 with the direction C contrary with direction B, and arrives fluid reducing agent injector 114 by gravity supply, thus convection cell reducing agent injector 114 cools.
The use of the DEF118 sprayed can reduce or eliminate the needs to exhaust gas recirculatioon (EGR).Therefore, DEF ejecting system is the indispensable parts of whole exhaust after treatment system substantially.Correspondingly, for the injector nozzle 124 of DEF ejector system, the use of cooling system 104 is quite valuable on the life-span extending injector nozzle 124, is thus quite valuable on the overall efficiency of such system.In addition, by using many compartments phase separation tank 136, can be minimized in coolant circuit 130 to needs that the are bulky and structure taken up room.
Should be appreciated that foregoing description only for illustrative purposes, and limit scope of the present utility model never in any form.Therefore, it will be appreciated by those skilled in the art that other side of the present utility model can by studying accompanying drawing, the utility model text and appended claims and obtain.
