Specific embodiment
The utility model will be further described below with reference to the accompanying drawings, but is not subject in any way to the utility model
Limitation instructs made any changes and modifications based on the utility model, belongs to the protection scope of the utility model.
As shown in Figure 1, the utility model includes outer tube 1 and the inner tube 2 that is installed in outer tube 1,1 inner wall of outer tube and inner tube 2
The space formed between outer wall is air ventilation passage 3, in use, liquid is passed through into inner tube 2, into air ventilation passage 3
It is passed through gas, spiral plate 4 is provided in air ventilation passage 3, the inside of spiral plate 4 is fixedly connected with inner tube 2, outside and outer tube
There are free gap between 1 inner wall, the effect of spiral plate 4 is, first is that realize that the eddy flow of gas outlet gas projects, second is that
Even heat between outer tube 1 and inner tube 2 can preferably be taken away during helical flow, make outer tube 1 will not office by gas
Cause thermal damage is crossed in portion.
Outer tube 1 can be used heat-resisting material and be made, and when the use of this atomizing lance is in burner, outer tube 1 is especially
The nozzle 7 of outer tube 1, is generally all located at the inside of burner, and the temperature being subject to is higher, in order to guarantee the use longevity of atomizing lance
Life reduces the frequency of maintenance and replacement, and outer tube 1 and nozzle 7 are made of material resistant to high temperature, in practice according to temperature the case where
Stainless steel or other materials can be selected, 316L stainless steel can be such as selected.When in use, the nominal bore diameter of inner tube 2 is chosen as
20mm, the nominal bore diameter of outer tube 1 are chosen as 65mm, and respective length determines as needed.
One end of outer tube 1 is provided with flange 5, is provided with air inlet pipe 6 on 1 side wall of outer tube close to flange 5, outer tube 1
The other end is provided with the nozzle 7 with 1 integrally connected of outer tube, and venthole is machined on nozzle 7, and the end of inner tube 2 passes through venthole
The outside for reaching nozzle 7, the length generally stretched out is shorter, is advisable with that can reach preferable atomizing effect, is specifically stretched out
Length can determines according to actual conditions, and there are the outlet passageways 8 of annular between 2 outer wall of venthole and inner tube, in general, outlet
Gap between 2 outer wall of hole and inner tube is smaller, can make the gas pressure high flow rate in air ventilation passage 3 fast in this way, be conducive to
The atomizing effect of liquid.
It is connected with sealing plate 9 on the outer wall of inner tube 2, is connected between sealing plate 9 and flange 5 by gasket, stud and nut seal,
It is flexibly connected between sealing plate 9 and outer tube 1 by flange, when needing repairing, unclamps the stud nut on flange, so that it may by inner tube
2 components are integrally extracted out from outer tube 1, easy to repair.
The course of work of the utility model is: being passed through liquid from inner tube 2, while being passed through gas from air inlet pipe 6, gas is in gas
Flowing in body circulation passage 3 carries out screw type flowing along spiral plate 4 by gas when spiral plate 4, and is passing through spiral plate 4
The spiral flow mode is still kept afterwards, and last spiral air flow is sprayed out of outlet passageway 8, and liquid is then from the end of inner tube 2
It sprays, liquid forms the state of " bellows chamber water " with air-flow, at this moment liquid is constantly had with air-flow in the effective diffusing in exit
Sequence contact, collision, the liquid crushing droplet cluster tiny at diameter, atomizing effect is good, and in this process, destructive distillation knot in liquid
Brilliant dirt is easily blown away in time by air-flow, avoids the problem that obstruction.The utility model uses spiral gas during liquid is atomized
Stream, spiral air flow can accelerating liquid be broken into the speed of drop, improve nebulization efficiency, broken droplet cluster is also more tiny；
Secondly, being flexibly connected between outer tube 1 and inner tube 2 by flange, installation and removal are more convenient, facilitate when needing repairing fast
It is prompt；In addition, gas flows in air ventilation passage 3, the heat between inner tube 2 and outer tube 1 can be taken away in time, to outer tube 1
Cooling effect is played, so that the high temperature resistance of outer tube 1 improves, the service life is longer.
Preferably, the shape of nozzle 7 is cone, and the diameter of circular cone is gradually reduced with the flow direction of gas, in this way
Setting be because cone fluid behaviour it is preferable, according to actual needs, the good shape of other fluid behaviours also can be selected in nozzle 7
Shape.
It is connected between sealing plate 9 and the outer wall of inner tube 2 by 10 air-tight movable of sealing ring, the effect of sealing ring 10 is outside preventing
Gas leakage in pipe 1, but the axial movement between sealing plate 9 and inner tube 2 is not interfered, it is provided in the inner tube 2 in 9 outside of sealing plate
Regulating mechanism, regulating mechanism include adjustable plate 11 and adjust bolt, and adjustable plate 11 is fixed in inner tube 2, adjusts the spiral shell of bolt 12
Line end is screwed into sealing plate 9 after passing through adjustable plate 11, and reset spring 13 is provided between adjustable plate 11 and sealing plate 9.Regulating mechanism
Adjustment process be: the adjusting bolt 12 on rotation adjustable plate 11, at this moment there are two types of situation, first is that being screwed into envelope for bolt 12 is adjusted
In plate 9, shorten the distance between adjustable plate 11 and sealing plate 9, then the extended length of nozzle 7 is stretched out in 2 end of inner tube；Conversely, increasing
The distance between long adjustable plate 11 and sealing plate 9, the length that nozzle 7 is stretched out in 2 end of inner tube shortens, and reset spring 13 is then located always
In compressive state, so that adjusting bolt 12 is in Pre strained state, its loosening can be prevented.By above-mentioned adjusting, inner tube 2 can be changed
With the relative axial position of outer tube 1, so as to adjust atomizing effect.
Oblique section or arc section are processed into the end that nozzle 7 is stretched out in inner tube 2, can increase by 2 liquid outlet of inner tube in this way
Effective diffusing effect at place utilizes the atomizing effect for improving liquid.
The central axis of inner tube 2 and the central axis of outer tube 1 coincide, and the utility model can be made to carry out mist in this way
When change, it will not cause to be atomized non-uniform situation due to inner tube 1 and the bias of outer tube 2.
