Description
Technical field
It the utility model is related to diesel motor exhaust processing gas and help injection apparatus field, more particularly to diesel engine
Vent gas treatment gas helps the inside and outside mixing Anti-clogging spray nozzle of injection apparatus gas-liquid.
Background technology
Common gas-assisted nozzle sprays tail gas reductant and motor exhaust into 90 degree, so nozzle is processed into elbow-shaped
Formula, 4 micropores are reprocessed in bend part.Because this elbow-for-nozzle form can increase additional friction, make reducing agent quick
Spray from nozzle, microcell length is long in addition more aggravates resistance, and then in the presence of exhaust high temperature reducing agent in nozzle interior and
Spray orifice position easily forms crystallization, and crystallization progressive one is heated at high temperature, and forming condensation product not soluble in water makes its nozzle complete
Block.

Tool formula nozzle, is easy to arrangement, it is not necessary to which extra cooling system, maintenance easy to maintain, cost advantage are obvious.
Brief description of the drawings
Fig. 1 is that the diesel motor exhaust of embodiment handles the signal that gas helps the inside and outside mixing Anti-clogging spray nozzle of injection apparatus gas-liquid
Figure.
Embodiment
In order to deepen to understanding of the present utility model, the utility model is done further below in conjunction with drawings and examples
It is described in detail, the embodiment is only used for explaining the utility model, and the scope of protection of the utility model is not formed and limited.
Embodiment
Mixed as shown in figure 1, present embodiments providing a kind of diesel motor exhaust processing gas and helping inside and outside injection apparatus gas-liquid
Anti-clogging spray nozzle is closed, it includes interior gaseous mixture liquid pipe 2, outer mixture pipe 7, mounting flange 3 and shower nozzle 4；The interior gaseous mixture liquid pipe 2
The top of mounting flange 3 is vertically mounted at outer mixture pipe 7；The shower nozzle 4 is vertically mounted at the bottom of mounting flange 3；In described
The top of gaseous mixture liquid pipe 2 is provided with reducing agent connector 1；The top of the outer mixture pipe 7 is provided with outer mixing air and connect
First 8；Outer mixing compression ring 5 is provided with the side wall of the shower nozzle 4；The outer mixing compression ring 5 connects with outer mixture pipe 7；It is described
The center of outer mixing compression ring 5 is provided with interior mixing spray orifice 6；The interior mixing spray orifice 6 connects with interior gaseous mixture liquid pipe 2；It is anti-
Stifled nozzle is vertically mounted on blast pipe, and the spray direction of the interior mixing spray orifice 6 of shower nozzle 4 is consistent with engine exhaust flow direction.
The diesel motor exhaust processing gas of the present embodiment helps the inside and outside mixing Anti-clogging spray nozzle of injection apparatus gas-liquid, diesel engine
By after reducing agent accurate measurement, reducing agent is mixed metering units in tail gas processing system with built in air control unit
Close, after forming gas liquid mixture, enter through reducing agent connector in the interior gaseous mixture liquid pipe of this spray nozzle device, by the push of gas
After reducing agent is pushed into interior mixing spray orifice, the further atomization of gas-liquid that outer mixing compression ring internally mixes spray orifice is smaller diameter
Grain, formed outside gas-liquid and mixed, then sprayed into the exhaust pipe of engine, in the presence of exhaust high temperature reducing agent pyrolysis for ammonia and
Nitrogen oxides in motor exhaust is reduced to nitrogen and water in the presence of catalyst again, started so as to purify by water, ammonia
Tail gas；This nozzle can be such that reducing agent quickly sprays from nozzle, also not have a resistance without the pressure loss, and with motor exhaust air-flow
Always, and reducing agent atomizing particle is minimum, thus further improve diesel motor exhaust processing unit reliability and efficiently
Property；This nozzle is installed perpendicular to the exhaust pipe of engine, is advantageous to arrangement and engine exhaust system arrangement；This nozzle it is interior
It is consistent with engine exhaust flow direction to mix the spray direction of spray orifice, does not form residual, reduces the Crystallization Plugging after reducing agent residual
Risk, also reduce blast pipe internal crystallization risk
The diesel motor exhaust processing gas of the present embodiment helps the inside and outside mixing Anti-clogging spray nozzle of injection apparatus gas-liquid, reducing agent spray
When going out, no pressure loss and resistance, the interior mixing of gas-liquid and outer mixed phase combine to form smaller gas-liquid particle diameter, improve atomization
Quality and catalyst reduction efficiency, the Crystallization Plugging risk after reducing agent residual is reduced, Mechanical nozzle, is easy to arrangement,
Extra cooling system is not needed, maintenance easy to maintain, cost advantage is obvious.
Above-described embodiment should not in any way limit the utility model, all by the way of equivalent substitution or equivalency transform
The technical scheme of acquisition is all fallen within the scope of protection of the utility model.
