Obtain after fully burning to greatest extent, be ejected into through going out fire expansion leaf 14 by lighting a fire in the combustion chamber that fire expansion leaf 14 is constituted
The air-flow mixing chamber that device fan blade oversheath 15 and flow spoiler are constituted, through going out fire expansion leaf 14 rectification, herein thermal current with
Flame is in clockwise（Counterclockwise）Rotation, while rectification of the engine exhaust through taper air flow guiding leaf 13, into air-flow mixing
The air-flow of room is also in clockwise（Counterclockwise）Rotation, thermal current, flame, motor exhaust further burn in air-flow mixing chamber
And after being well mixed, the flow-disturbing through flow spoiler can discharge mixed airflow straight uniform）, it is ensured that discharge air-flow mixing chamber
The uniformity of air flow rate and Temperature Distribution, so as to ensure the random effective and DPF of temperature control point complete regeneration.Diesel engine
The special fluid radome fairing of DPF low-temp recovery igniters sprays flame in diameter 4cm caliber, by repeatedly mixing, fully
Burning, finally make it that thermal current is diffused into a diameter of 30cm planes, gas flow temperature is consistent with uniform flow distribution, and temperature reaches
To more than 600 DEG C.
It is to be understood that：Although above-described embodiment is contrasted to the mentality of designing of the present invention, detailed word is retouched
State, but these word descriptions, simply to the simple text description of mentality of designing of the present invention, rather than to mentality of designing of the present invention
Limitation, any combination without departing from mentality of designing of the present invention, increase or change, each fall within protection scope of the present invention.
Claims (1)
1. a kind of special fluid radome fairing of Diesel engine DPF low-temp recovery igniters, it is characterized in that：Loudspeaker air heat storage tube is big
Mouth end is equipped with out fire expansion leaf, and taper air flow guiding leaf is distributed in loudspeaker air heat accumulation pipe outer wall；Loudspeaker air heat storage tube is used
Stainless steel reduced pipe, it can play a part of stable and guide to burned flame, while ensureing that fuel oil can fully burn；Taper gas
Conductance stream leaf uses special stainless steel plate, and it can be to engine exhaust through row rectification；Go out fire expansion leaf and use stainless steel pressing,
It gentle to flame can flow through the rectification of row clockwise or counterclockwise, play uniform dispersed flame and thermal current, make it
Equably to DPF traps speed end face by thermal regeneration inward outside, so as to avoid flame and thermal current from concentrating a zonule pair
DPF heating, solves the problem of the caused DPF frequent regenerations of DPF artefacts regeneration.
