Description
Technical field
The utility model is related to slurrying alkali recovery technology field, specifically a kind of black liquor atomizing lance.
Background technology
In recent years, with the continuous improvement of environmental requirement, alkali recovery technology has obtained developing on a large scale very much in China, especially wooden
The recovery technology for starching black liquor, is equipped by Importing Foreign Advanced Technology so that the alkali recovery furnace in China obtains increasingly perfect, items
Index has reached higher level.Extraction rate of black liquor, which is substantially all, reaches 95%, up to 98%, and alkali recovery is more than 93%, is had
Even as high as 98%, some enterprise's alkali degrees of self-sufficiency reach 100%, substantially carry out alkali self-sufficiency.
The pattern of black liquor atomizing lance can be baffle plate type, be vortexed tapered, CEU types, in order to make black liquor effectively convert
At chemicals and thermal energy, black liquor must be atomized into droplet-like, and at the same time being ejected into reclaimer.Existing black liquor atomization spray
There is also many deficiencies when in use for rifle：1, liquid atomizing effect is poor, 2, black liquor wall easy to stick fall extension.
Invention content
The technical assignment of the utility model is in view of the deficiencies of the prior art, to provide a kind of black liquor atomizing lance, solve
Now have deposited in technology liquid atomizing effects it is poor, black liquor wall easy to stick falls extension the problem of
Technical solution adopted by the utility model to solve its technical problems is：
The end of a liquid atomizing lances, including spray gun diversion rod, spray gun diversion rod is provided with nozzle, and the spray gun is led
The inner cavity of flow post is fluid passage, which is used to convey liquid to nozzle, and spray gun diversion rod is oriented to using bend pipe baffling,
Spray gun diversion rod is that venturi is tapered.
As the utility model it is further preferred that the arrival end aperture of the nozzle is tapered hole, outlet end aperture is
Flaring hole, tapered hole are dovetail groove face with flaring hole boundary section.
As the utility model it is further preferred that being connected with baffling injection baffle plate below the nozzle.
As the utility model it is further preferred that the baffling injection baffle plate is in plane sector.
As the utility model it is further preferred that baffling injection baffle plate upper end is tilted to nozzle direction.
As the utility model it is further preferred that the nozzle end have one it is compatible with baffling injection baffle plate not
Symmetric pyramid is open.
As the utility model it is further preferred that the end of the nozzle and spray gun diversion rod is welded to connect.
As the utility model it is further preferred that a whole set of atomizing lance black liquor injection pressure is 0.6 Mpa.
A kind of black liquor atomizing lance of the utility model, compared with prior art caused by advantageous effect be：
1, it is tapered to be designed as venturi for spray gun diversion rod, convenient for black liquor is accelerated in spray gun, spray gun diversion rod end
Nozzle, play level-one atomizing；Level-one Wuization liquid drop, to be mapped at a high speed in baffling injection baffle plate, carry out it is secondary
Atomization reduces the viscous wall of black liquor and falls extension；Drop after the secondary-atomizing of part is reflected by tapered opening, again by droplet distribution；
2, nozzle is designed as tapered divergent structure, when black liquor enters flaring hole by tapered hole, because of diffusion suddenly, causes side
Portion's effect so that the liquid in nozzle spreads out to form the spray, and cooperation dovetail groove face design carries out the spray to spread out
Reflection, further dispersant liquid drop；
3, after multistage atomizing little liquid particle, easy firing, reduce flying dust.
Description of the drawings
Attached drawing 1 is the structure chart of the utility model black liquor atomizing lance；
Attached drawing 2 is the structure chart of the utility model nozzle；
Attached drawing 3 is the structure chart of the utility model baffling injection baffle plate.
In figure, 1, spray gun diversion rod, 2, nozzle, 20, tapered hole, 21, flaring hole, 22, dovetail groove face, 23, tapered opening,
3, baffling injection baffle plate, 4, fluid passage.
Specific implementation mode
1-3 below in conjunction with the accompanying drawings is described in detail below a kind of black liquor atomizing lance of the utility model.
As shown in Fig. 1, a kind of black liquor atomizing lance of the utility model, including spray gun diversion rod 1, spray gun diversion rod 1
End be welded with nozzle 2, the inner cavity of the spray gun diversion rod 1 is fluid passage, which is used to convey liquid to nozzle 2
Body, spray gun diversion rod 1 are oriented to using bend pipe baffling, and spray gun diversion rod 1 is that venturi is tapered.
As shown in Fig. 2, the arrival end aperture of nozzle 2 is tapered hole 20, and outlet end aperture is flaring hole 21, tapered hole 20
It is dovetail groove face 22 with 21 boundary section of flaring hole.2 tapered flaring of nozzle designs, and effect is that black liquor is entered by tapered hole 20
When flaring hole 21, because of diffusion suddenly, cause edge effect so that the liquid in nozzle 2 spreads out to form the spray, coordinates dovetail
Groove face 22 designs, and reflects the spray to spread out, further dispersant liquid drop.
Wall is glued to be further reduced black liquor, the lower section of nozzle 2 is connected with baffling injection baffle plate 3, it is preferable that baffling injection baffle plate
