Abstract
The utility model discloses a high power diesel engine exhaust aftertreatment system for test bench position, including no. 1 diesel smoke mouth, three -way pipe, high temperature butterfly valve, no. 2 diesel smoke mouths, SCR exhaust aftertreatment device and chimneys, an interface of three -way pipe passes through pipeline and no. 1 diesel smoke mouth intercommunication, and another interface just is provided with the high temperature butterfly valve on the pipeline through pipeline and no. 2 diesel smoke mouth intercommunications, and a third interface passes through the pipeline and communicates with the chimney, SCR exhaust aftertreatment device and chimney intercommunication. The beneficial effects of the utility model are that: adopted the SCR exhaust aftertreatment device, effectively the pollution abatement improves environmental quality, adopt the structure of butterfly valve and three -way pipe combination, realized SCR exhaust aftertreatment device of two model experiment sharings, practiced thrift tail gas treatment cost greatly, the problem of the built -in purify with high costs, the degree of difficulty is big is solved to the discharge performance that has improved the diesel engine.
Description
Technical field
The utility model relates to Diesel Engine Technique Field, particularly a kind of high-power diesel engine exhaust gas aftertreatment system for test bench location.
Background technology
Abgasgesetz is more and more higher to the emission request of diesel engine, in current factory, high-power diesel engine emission testing performs the emission standard of IMOTierII, but new Abgasgesetz proposes, the emission request of diesel engine is harsher, and the tail gas of diesel engine test discharge is untreated directly to be entered air by sound damper and is namely regarded as being polluted by environment. Implementing more difficult due to emission controls by improving combustion technology and cost is higher, exhaust gas aftertreatment techniques just becomes the important means reducing tail gas pollution. High-power diesel engine must do break-in experiment before dispatching from the factory, join machine experiment, emission testing, experiments in hundred hours etc., the environment of plant can be polluted by these tests, consequently, it is desirable to transformed by test bench location, the newly-increased tail gas to test bench location carries out the system of purifying treatment, thus the tail gas making diesel emission relatively easily reaches IMOTierIII emission standard.
Existing diesel engine test platform does not still have post-treatment measure, and diesel engine vent gas directly enters air through sound damper, is polluted by environment. And exhaust aftertreatment technology just has use in small power high-speed engine, then seldom using on high-powered medium-speed diesel engines, undressed discharge can only reach IMOTierII emission standard, can not meet the requirement of Abgasgesetz.
Practical novel content
Goal of the invention of the present utility model is: for above-mentioned Problems existing, a kind of high-power diesel engine exhaust gas aftertreatment system for test bench location is provided, solve high-power diesel engine dispatch from the factory before a series of test problem that environment is polluted, improve high-power diesel engine emission standard, make product adaptation market development demand.
The technical solution adopted in the utility model is such:
A kind of high-power diesel engine exhaust gas aftertreatment system for test bench location, comprise Numberl diesel fuel machine smoke outlet, Y-tube, high temperature butterfly valve, No. 2 diesel engine smoke outlets, SCR tail-gas after treatment apparatus and chimney, an interface of described Y-tube is connected with Numberl diesel fuel machine smoke outlet by pipeline, another interface is connected with No. 2 diesel engine smoke outlets by pipeline and is provided with high temperature butterfly valve on pipeline, 3rd interface is connected with chimney by pipeline, and described SCR tail-gas after treatment apparatus is connected with chimney.
As preferably, also comprise the pressure transmitter, temperature sensor, the under meter that are arranged on SCR tail-gas after treatment apparatus and carry out the Controlling System of Comprehensive Control.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
1, have employed SCR tail-gas after treatment apparatus, can effective decreasing pollution, it is to increase environmental quality.
2, butterfly valve and the structure of Y-tube combination is adopted, it is achieved that two type experiments share a SCR tail-gas after treatment apparatus, have greatly saved vent gas treatment cost.
3, solve emission controls by improving combustion cost height, problem that difficulty is big, thus improve diesel engine emission behavior.
Accompanying drawing explanation
Fig. 1 is vertical view of the present utility model.
Figure marks: 1 is Numberl diesel fuel machine smoke outlet, and 2 is Y-tube, and 3 is high temperature butterfly valve, and 4 is No. 2 diesel engine smoke outlets, and 5 is SCR tail-gas after treatment apparatus, and 6 is chimney.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
Embodiment:
As shown in Figure 1, a kind of high-power diesel engine exhaust gas aftertreatment system for test bench location, comprise Numberl diesel fuel machine smoke outlet 1, Y-tube 2, high temperature butterfly valve 3, No. 2 diesel engine smoke outlets 4, SCR tail-gas after treatment apparatus 5 and chimney 6, an interface of described Y-tube 2 is connected with Numberl diesel fuel machine smoke outlet 1 by pipeline, another interface is connected with No. 2 diesel engine smoke outlets 4 by pipeline and is provided with high temperature butterfly valve 3 on pipeline, 3rd interface is connected with chimney 6 by pipeline, and described SCR tail-gas after treatment apparatus 5 is connected with chimney 6. Also comprise the pressure transmitter, temperature sensor, the under meter that are arranged on SCR tail-gas after treatment apparatus 5 and carry out the Controlling System of Comprehensive Control.
Described high temperature butterfly valve 3 is manual switchover mode.
The principle of SCR tail-gas after treatment apparatus 5 utilizes certain density urea reductive NOX, urea and water reaction generate ammonia, ammonia and NOXReaction generates harmless nitrogen and water. Pressure transmitter, temperature sensor, under meter distinguish the air pressure in collecting work process, temperature and flow signal, then send Controlling System to and process, as the foundation of control SCR tail-gas after treatment apparatus 5.
