Technique effect of the present invention is: product with compact structure of the present invention, occupies little space; Solve urea pyrolysis, problem that hydrolysis environment temperature is on the low side; Solve pipeline long and the urea mixing tube uniformity that produces and the contradiction (mix more even because of the longer urea of pipeline, but the temperature that air-flow enters converter being also lower) before waste gas heat insulation effect; Rational mixed construction, significantly improves the uniformity of air-flow and urea mixing, from achieving higher NOx catalytic conversion efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
In Fig. 1, comprise suction tude 1, urea nozzle 2, air inlet necking pipe 3, air inlet outer end cap 4, air inlet inner end cap 5, hole pipe 6, outer cylinder body 7, carrier 8, air outlet pipe 9, end cap 10 of giving vent to anger, dividing plate 11, liner 12, air inlet wall 13, inner barrel 14, thermal insulating pad 15, necking down Taper Pipe 16, connect end cap 17 etc.
As shown in Figure 1, the present invention is a kind of urea nozzle integrated form SCR catalytic converter, comprise outer cylinder body 7, described outer cylinder body 7 inlet end fixes perforated pipe 6, the built-in necking down Taper Pipe 16 of hole pipe 6, tubular connecting end lid 17 is fixed in hole pipe 6 front end, hole pipe 6 the inner is fixedly connected with air inlet blanking cover 13, and air inlet blanking cover 13 is designed to semicircle, and object is the atomization space increasing urea liquid, described connection end cap 17 outboard end is fixedly connected with suction tude 1, and the end face connecting end cap 17 is equipped with urea nozzle 2; Described outer cylinder body 7 inner chamber, be fixedly installed carrier 8 corresponding to the rear end of hole pipe 6, air outlet pipe 9 is fixed on the outlet side of outer cylinder body 7 by dividing plate 11 and end cap 10 of giving vent to anger.
Necking down Taper Pipe 16 collar extension is large, interior young.
Hole pipe 6 is fixedly connected on the inlet end of outer cylinder body 7 by air inlet outer end cap 4, air inlet inner end cap 5.
Air outlet pipe 9 is arranged at position on the lower, outer cylinder body 7 inside.
The air inlet end of suction tude 1 forms air inlet necking pipe 3, can be accelerated after waste gas enters, and utilizes and dispels the urea liquid sprayed into.Under the acceleration of air inlet necking pipe 3, after waste gas mixes with urea liquid, after the further mixed function of hole on most of passing hole pipe 6, flow into air-inlet cavity, and inner by carrier 8, flowed out by air outlet pipe 9 after carrier rectification.
Connect end cap 17 in cone tubular, urea nozzle 2 is arranged on the conical surface of connection end cap 17, and the center line of urea nozzle 2 extends on necking down Taper Pipe 16, makes urea liquid wall broken.
Outer cylinder body 7 corresponds to hole pipe 6 place and forms air-inlet cavity, and between air-inlet cavity and outer cylinder body 7 inwall stuffed heat insulated cotton 15, heat insulation foam 15 is in order to ensure the ambient temperature of urea pyrolysis and hydrolysis in air-inlet cavity, and laying temperature is too low causes urea crystals.Between carrier 8 and outer cylinder body 7 inwall, liner 12 is set.
Both hole pipe 6 in product of the present invention and air outlet pipe 9 circumferential surface is laid with some holes, and supplied gas is passed through.
State four and before product in, traditional SCR aftertreatment system arrangement is arranged on the gas exhaust piping of catalytic converter front end urea nozzle.Because the pyrolysis of urea in this mixing tube, hydrolysis and mixed effect directly affect the performance of SCR system, therefore exist this pipeline in product design process and be strict with, as the required distance of this pipeline and converter, geometrical shape require, thermal insulation property requirement etc.
Product of the present invention is in the early development stage, and designer and analyst will spend a large amount of energy to be optimized this section of pipeline; Later stage tries every possible means again and solves the insulation problem of this section of pipeline.In addition, due to the restriction of arrangement space in car load, be difficult to meet design requirement in the confined space by the design of traditional arrangement mode.Urea nozzle is integrated in SCR catalytic converter, not only can solves the problem that space is arranged, overall structure can also be made simpler.
At present, the biggest problem that Conventional urea nozzle integrated form SCR system faces be due to mixing apart from short, space is little and occur the problem that NOx catalytic conversion efficiency is low.
