Description
Technical field
This utility model relates to Diesel engine SCR aftertreatment system technical field, particularly relates to a kind of mixing disturbing flow device。
Background technology
Along with national environmental protection portion announces, from 1 day July in 2012, China implemented light-duty vehicle fourth stage discharge standard in China, will be unable to enter Ministry of Industry and Information's new car bulletin not up to the light-duty vehicle of state's IV discharge standard。Latest national standards, the 5th stage state motor vehicle discharge standard will be implemented in the whole nation in 1 day January in 2018, Beijing will in 1 day January in 2016 early excise the 5th stage state motor vehicle discharge standard。Diesel engine SCR post-processing technology is the technology adopted meeting the country such as state IV, state V Abgasgesetz。Present price section SCR aftertreatment system can meet state IV emission request, but is difficult to meet state's V emission request。
Utility model content
The purpose of this utility model is in order to solve the problem that SCR aftertreatment system is difficult to meet state's V emission request, provide a kind of mixing disturbing flow device, between nozzle and SCR catalyst, a blender is arranged in a distance, flow-disturbing chamber is installed between blender and SCR catalyst, by blender and flow-disturbing chamber, improve the mixability of motor exhaust and NH3 and the uniformity of air velocity distribution to improve NOx conversion efficiency, meet state's V emission request。
Solve the technical problem that required by this utility model and can be achieved through the following technical solutions:
A kind of mixing disturbing flow device, including offgas duct, nozzle, SCR catalyst, described nozzle is arranged on the front end of offgas duct, described SCR catalyst is arranged on the rear end of offgas duct, between described nozzle and SCR catalyst, blender is installed, being provided with flow-disturbing chamber between described blender and SCR catalyst, described flow-disturbing intracavity is provided with porous plate, antipriming pipe。
Further, described blender includes blade。

Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with being specifically illustrating, this utility model is expanded on further。
When being embodied as, in conjunction with Fig. 1, Fig. 2, a kind of mixing disturbing flow device, including offgas duct 1, nozzle 2, blender 3, end cap 5, antipriming pipe 6, porous plate 7, flow-disturbing chamber 8, SCR catalyst 9, SCR catalyst housing 10。Nozzle 2 is arranged on the front end of offgas duct 1, and SCR catalyst 9 is arranged on the rear end of offgas duct, is provided with blender 3 between nozzle and SCR catalyst, is provided with flow-disturbing chamber 8 between blender and SCR catalyst, and flow-disturbing intracavity is provided with porous plate 7, antipriming pipe 6。
A blender is arranged in a distance, urea nozzle rear end。The structure of blender is made up of 4 blades, and the sector of each blade essentially 1/4 circle, each blade is angled along one edge break。Blender is as shown in Figure 2。The effect of this blender is to be sufficiently mixed with motor exhaust in exhaustor by NH3。
In blender rear end, SCR catalyst leading portion certain distance go out install a flow-disturbing chamber。Flow-disturbing chamber is to be welded by antipriming pipe 6, porous plate 7 and catalyst housing 10, end cap 5。The effect in flow-disturbing chamber is, by antipriming pipe and porous plate, air-flow is carried out water conservancy diversion, makes the air-flow can uniformly across SCR catalyst。Porous plate can be corrosion resistant plate。Antipriming pipe can be stainless steel tube。
SCR aftertreatment system conversion ratio with mixing disturbing flow device is apparently higher than the situation without blender, the transformation efficiency of NOx on average improves 16.75%, the visible suitable mixing disturbing flow device transformation efficiency to raising NOx that installs additional before catalyst is by remarkable effect, meet state's V emission request, avoid the leakage of NH3 and the crystallization again of carbamide simultaneously。During with mixing disturbing flow device, SCR catalyst front end face air flow method is evenly, and gas enters in mixing disturbing flow device and forms eddy current, is conducive to gas component to spread。
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described。Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description is that principle of the present utility model is described; under the premise without departing from this utility model spirit and scope, this utility model also has various changes and modifications, and these changes and improvements both fall within the scope of claimed this utility model。This utility model claims scope and is defined by appending claims and equivalent thereof。
