Description
Technical field
The utility model relates to acoustic wave ash ejector technical field, particularly a kind of horn for acoustic wave ash ejector.
Background technology
Boiler is in production run process, its heating surface is as superficial dust and slagging scorification such as water-cooling wall, superheater, economizer, preheater and flues, that long-standing problem production and is difficult to the problem of solution, not only make boiler heating surface conduct heat to weaken, cause boiler thermal output to reduce, reduce and produce load, and, when fouling of heating surface and slagging scorification serious time, also may cause unexpected blowing out, cause heavy economic losses.
Acoustic wave ash ejector compressed air or steam is converted to high-power sound wave to send in stove, when the dust stratification on heating surface be subject to repeatedly drawing with the dilatational wave of certain frequency alternately change, pressure effect time, come off because fatigue is loose, take away with flue gas stream, or under gravity, sink to ash bucket and discharge.
The effect of horn in sound wave soot blowing system is exactly lead and improve the pulse energy produced by sonic generator, make its direction of propagation Relatively centralized or be diffused into the region of specifying and increase acoustic load, the professional horn that whether reasonable design, configuration be, directly will affect the final working effect of the grey device of sound wave soot blowing system.
Summary of the invention
The utility model object is to provide a kind of horn for acoustic wave ash ejector, and its cross section is by import rectangular or trapezoidal expansion to outlet, and the acoustic wave energy that sonic generator can be produced conduct to the heating surface needing to purge compared with small loss.
Based on the problems referred to above, the technical scheme that the utility model provides is:
A kind of horn for acoustic wave ash ejector, comprise the horn header board connecting into horn-like cylindrical shell, plate after horn, horn left plate and horn right plate, wherein said horn header board and area along its length flaring identical with plate shape after described horn, described horn left plate and described horn right plate are index flexure plane, the bending radius of described horn left plate is less than described horn right plate, the both sides, front and back of described horn left plate respectively with described horn header board, after described horn, plate connects, the both sides, front and back of described horn right plate respectively with described horn header board, after described horn, plate connects.
Further, the import of described horn is rectangular, and the outlet of described horn is rectangle or trapezoidal, and described import is mutually vertical with the cross section of described outlet.
Compared with prior art, the utility model has the advantages that:
1, the technical solution of the utility model is adopted, the sectional area of this horn rectangular or trapezoidal by import to outlet flaring, effectively can increase the radiation of sound source, not only there is public address effect and can also play poly-sound effective value simultaneously, the acoustic wave energy that sonic generator can be produced conducts to the heating surface needing to purge compared with small loss, the Slag and accumulating ash of heating surface is come off;
2, adopt the technical solution of the utility model, improve the operating efficiency of acoustic wave ash ejector, further increase the thermal efficiency of boiler, reduce and produce load and production cost.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of a kind of horn embodiment for acoustic wave ash ejector of the utility model;
Fig. 2 is the left view of Fig. 1;
Wherein: 1, horn left plate; 2, horn right plate; 3, horn header board; 4, plate after horn.
Detailed description of the invention
Below in conjunction with specific embodiment, such scheme is described further.Should be understood that these embodiments are not limited to for illustration of the utility model limit scope of the present utility model.The implementation condition adopted in embodiment can do further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in normal experiment.
In description of the present utility model, term " longitudinal direction ", " transverse direction ", " on ", D score, "front", "rear", "left", "right", " vertically ", " level ", " top ", " end ", " interior ", the indicating position such as " outward " or position relationship be for based on the orientation described in accompanying drawing or position relationship, for convenience of describing the utility model instead of referring to that described device or original paper must have specific orientation, therefore can not be interpreted as restriction of the present utility model.
See Fig. 1-2, for structural representation of the present utility model, a kind of horn for acoustic wave ash ejector is provided, it comprises horn header board 3, plate 4 after horn, horn left plate 1 and horn right plate 2, horn header board 3, plate 4 after horn, horn left plate 1 and horn right plate 2 connect into horn-like cylindrical shell, wherein horn left plate 1 and horn right plate 2 are index flexure plane, the bending radius of horn left plate 1 is less than horn right plate 2, horn header board 3 and its area along its length flaring identical with plate after horn 4 shape, horn left plate 1 and both sides, front and back respectively with horn header board 3, after horn, plate 4 connects, the both sides, front and back of horn right plate 2 respectively with horn header board 3, after horn, plate 4 is connected.
The import of horn is connected to sonic generator, and its rectangular and its cross section and horizontal plane, the outlet of horn is rectangle or trapezoidal, and the outlet of horn is mutually vertical with the cross section of import.
In this example horn rectangular in cross-section or trapezoidal by import to Way out flaring, not only there is the effect of public address, the effect of poly-sound can also be played, the acoustic wave energy that sonic generator produces is conducted to lose in the heating surface process that boiler need purge less, the Slag and accumulating ash of heating surface is more easily come off, improves the operating efficiency of acoustic wave ash ejector.
Above-mentioned example, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art person can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations of doing according to the utility model Spirit Essence or modification, all should be encompassed within protection domain of the present utility model.
