Description
Technical field
This utility model relates to a kind of atomizer, in particular to Multi-stage spiral atomizer.
Background technology
The nozzle being applicable to spray combustion process mainly has following a few class:
This kind of nozzle of one side vortex atomizing nozzle relies on one side atomization, and working medium is formed behind big spin chamber and is all homogenized
Film sprays, and interacts with the eddy flow being arranged in atomization gas channel exit, improves atomization quality, but because its atomization is only
One side, unsuitable for full-bodied working medium.
Two-sided vortex atomizing nozzle uses two-sided air high speed, strong eddy flow that serous coat is produced Strong shear power effect, comes
Improve the atomization quality of high viscosity working medium；But this kind of structure QI consumed rate is relatively big, requires higher to spray combustion process, it is impossible to be effectively improved
Fuel atomizing quality.
Impacting type atomizer impacting type atomizer multistage atomizing, runs into ram and carries out machinery mist in exit
Spraying after change, but its atomizing effect is bad, especially in the face of height emulsifying high-viscosity material to there is atomization uneven, from engineering
Require bigger.
In sum, existing technology or set up eddy flow, or set up ram, it is impossible to meet mud right in burner hearth spray combustion
The atomizing effect requirement of nozzle, it is impossible to realize the deflagrate of a large amount of mud.
Summary of the invention
The purpose of this utility model is the compact conformation providing a kind of eddy flow to combine with ram, is atomized uniform, mist
Change amount is big, processing and manufacturing simple Multi-stage spiral atomizer.
A kind of Multi-stage spiral atomizer, including interior expander 2, outer nozzle 3, interior shower nozzle 4, outer shower nozzle 5, cyclone 6, shock
Part 7, atomization gas air inlet 10, wherein cyclone 6 is arranged between inside and outside shower nozzle, and ram 7 is arranged on nozzle exit, atomization
Gas air inlet 10 is arranged on interior expander 2.
Outer shower nozzle and outer nozzle use routine to connect, the most threaded, welding；
Preferably it is respectively symmetrically on interior expander and interior shower nozzle and one group or two groups of four atomization gas air inlets are set, improve atomization
Effect；On interior outer nozzle, preferably connect extension tube attached 9, as atomization gas inlet tube；Preferably eddy flow is set between inside and outside shower nozzle
Device, cyclone provides helical duct as atomization gas passage, is allowed to be formed eddy flow, and cyclone uses routine to be connected to inside and outside shower nozzle
Between, the most threaded, pin links and bonded.Interior expander 2, interior shower nozzle 4, outer nozzle 3 and outer shower nozzle 5 define inside and outside two
Individual mixing chamber so that atomization gas and mud mix more abundant, the mud after atomization is sprayed by the aperture on outer shower nozzle 8 conical surface.
Outdoor pipe 1 is the inlet tube of mud, and extraneous pipe 9 is the inlet tube of atomization gas.
Shower nozzle arranges ram outside, forms mechanical atomization structure, and ram uses conventional shape such as cylindrical, square
Shape, prismatic, pref. cylindrical.When mud runs into ram, producing mechanical atomization effect, the existence of ram makes sludge slurry
Air-flow from four sides backwash, then sprays from the outlet opening of atomising head after frontal impact, utilizes the kinetic energy of slurry air-flow to increase one-level mist
Change.
This utility model provides secondary-atomizing structure to arrange, and therefore this utility model is to mud especially height emulsifying, height
Uniformly, atomization quantity is big for the atomization of viscosity mud.
The beneficial effects of the utility model:
This utility model uses inside and outside shower nozzle and nozzle to form nebulization channel, is arranged symmetrically with atomization gas and enters on inner nozzle
Pore, improves atomizing effect, and is additionally arranged cyclone at passage back segment so that atomization gas is by forming eddy flow after cyclone, same
Time be additionally arranged ram in the exit of nozzle, increase one-level mechanical atomization so that atomizing effect is greatly improved.
Nebulization channel major part of the present utility model is cylindrical tube, has higher mechanical strength.Simultaneously in inside and outside spray
Cyclone it is provided with, it is also possible to play the effect strengthening nozzle arrangements intensity between Tou.Processing and manufacturing of the present utility model is simple, weight
Measuring moderate, the many employings of overall structure are threaded, convenient dismounting and installation, can be widely applied in the spray combustion process of burner hearth.

Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
Seeing Fig. 1, this utility model includes extension tube attached 1, outer nozzle 3 and interior expander 2, is connected with extension tube attached 1 by welding.
Being provided with extension tube attached 9 and outer shower nozzle 5 on outer nozzle 3, its China and foreign countries' shower nozzle 5 is connected with outer nozzle 3 by screw thread.Additionally, in interior expansion
Have two on pipe 2 symmetrical atomization gas air inlet 10, interior shower nozzle 4 are passed through welding and be connected with interior expander, simultaneously at inside and outside jet pipe
Between equipped with cyclone 6, define the swirl channel of atomization gas, at the dead ahead of interior shower nozzle, cylindrical ram 7 by screw with
Outer shower nozzle 5 connects, and increases one-level mechanical atomization.
