Description
Technical field
This utility model is related to a kind of carbamide injection mixed cell for cartridge type depurator, belongs to vehicle maintenance service dress
Put technical field.
Background technology
SCR（Selective reduction catalyst converter）Technology is to eliminate nitrogen oxides in diesel exhaust gas（NOX）Main post processing
One of technology, has been increasingly becoming the reduction NO that Ge great engine works of China and post processing supplier selectXTechnology path.SCR
Technology coats the noble metal catalysts such as platinum, palladium i.e. on carrier, sprays into urea liquid, when the tail for being mixed with urea liquid in tail gas
When gas enters catalyst, under the catalytic action of catalyst, the ammonia that decomposes out in carbamide（NH3）With the NO in motor exhaustX
Generation redox reaction, generates nitrogen（N2）With water (H2O), so as to reducing NOXDischarge, meets discharge standard.
Currently in order to meeting state five, six discharge standard of state, diesel engine typically adopts DOC+DPF+SCR technology paths.In axle
Enter in " one " font cartridge type depurator that axle goes out, need in the cylinder between DPF carriers and SCR carriers, to increase a carbamide spray
Penetrate mixed cell.One crucial effect of carbamide injection mixed cell is exactly to be sufficiently mixed urea liquid with air, and
Evenly into SCR carrier inlet end faces.Existing injection mixed cell integrated level is not high, is difficult to install in cartridge type depurator
Arrangement, particularly structural compactness is difficult to meet state five, the requirement of state six.Additionally, urea liquid runs into low temperature, dead space area
Easily crystallize, and in state five, the post processing scheme of state six, carbamide spray emitted dose also increases many, which increases carbamide knot
Brilliant risk.
Content of the invention
The purpose of this utility model is to spray urea liquid after mixed cell to solve increase carbamide in cartridge type depurator
Run into the problem of the easy crystallization in low temperature, dead space area, there is provided a kind of simple structure, compact to design for cartridge type depurator
Carbamide injection mixed cell.
This utility model is adopted the following technical scheme that：A kind of carbamide injection mixed cell for cartridge type depurator, including
Eddy flow mix aperture pipe, the eddy flow mix aperture pipe are arranged in housing, are provided with Z-shaped cutoff board in the housing, described Z-shaped every
Stream plate includes that the first arc plate, flat partition board and the second arc plate, first arc plate are vertically connected on one end of flat partition board, institute
State the other end that the second arc plate is vertically connected on flat partition board, middle part of the eddy flow mix aperture pipe through flat partition board, the shell
One end of body is provided with urea nozzle, and the enclosure interior is provided with catalyst carrier.
Further, the upper end of the eddy flow mix aperture pipe is provided with inlet channel, the lower end of the eddy flow mix aperture pipe
It is provided with some ventholes on tube wall, the eddy flow mix aperture pipe is internally provided with swirl vane.
Further, the lower end of the eddy flow mix aperture pipe is provided with several square openings with housing junction.
Further, first arc plate, be respectively arranged with arc opening groove between the second arc plate and housing.
Further, a diameter of 6-10mm of the venthole.
This utility model simple structure, compact to design, easy to use, enclosure interior is provided with Z-shaped cutoff board and makes air-flow point
Into two parts, by the upset air-flow of eddy flow mix aperture pipe, realize that carbamide enters SCR carrier ends after being sufficiently mixed with tail gas
Face, carbamide good mixing effect, carbamide nodeless mesh.
