A kind of efficient cyclone flue structure, including flue and walling of flue, the flue include separator aditus laryngis, downward main pipeline and upward subtube, the separator aditus laryngis flare;The central point of downward main pipeline cross section is O, and the side wall portion inner end of separator aditus laryngis and the round wall portion junction of downward main pipeline form protrusion A, and another side of sidewall portion inner end of separator aditus laryngis and the round wall portion of downward main pipeline are tangent, interface point B;The angle that the separator aditus laryngis is tubaeform is 20 24 °, and OA lines and OB link groups are angled 60 64 °;In separator aditus laryngis, the vertical range between wall portion is 800 860mm to protrusion A corresponding thereto;The walling of flue is composite layer refractory wall, and composite layer refractory wall includes fire brick layer, thermal insulation concrete layer and aluminosilicate fiberboard layer from the inside to the outside.The utility model has the beneficial effects that:Separator aditus laryngis shape reasonable design, makes flow velocity improve, and the centrifugation of cyclone cylinder rises, and the separative efficiency of circulating ash increases substantially.

Description

A kind of efficient cyclone flue structure
Technical field
The utility model is a kind of separator flue structure, more particularly to a kind of efficient cyclone flue structure belongs to rubbish Rubbish burning boiler equipment technical field.
Background technology
The different fluid bed garbage fired boiler that recirculates is common large-scale garbage burning boiler in garbage burning boiler.It is different heavy Burning, the heat transfer of recirculating fluidized bed garbage fired boiler all be unable to do without the participation of a large amount of circulating ash, and separator outer perimeter linear velocity is put down The momentum just generated is the key that centrifugal force.It commonly uses in the different fluid bed garbage fired boiler that recirculates, the separation of separator flue structure The design of device aditus laryngis shape is unreasonable, causes flow velocity to decline, the centrifugation of cyclone cylinder is made to be declined, will be greatly lowered The separative efficiency of circulating ash, it is 16.7m/s to make separator aditus laryngis flue gas flow rate, and separator inlet flow velocity is relatively low so that separation The separative efficiency of device reduces.And walling of flue refractoriness is relatively low, and it is fragile during use, it needs often to repair.
Utility model content
The purpose of this utility model is showed for the separator flue structure of the above-mentioned different fluid bed garbage fired boiler that recirculates Have in technology, there are the separator aditus laryngis shape of separator flue structure design it is unreasonable cause flow velocity to decline, cyclone cylinder from Centrifugalization is declined, the defect for making the separative efficiency of circulating ash be greatly lowered, and provides a kind of efficient cyclone cigarette Road structure can reach the separator aditus laryngis shape reasonable design of separator flue structure, so that flow velocity is improved, the centrifugation of cyclone cylinder Centrifugation rises, the purpose that the separative efficiency of circulating ash increases substantially.
To achieve the goals above the technical scheme adopted by the utility model is that:A kind of efficient cyclone flue structure, packet Flue and walling of flue are included, the flue includes separator aditus laryngis, downward main pipeline and upward subtube, and the separator aditus laryngis is in It is tubaeform;The central point of downward main pipeline cross section is O, the circle of side the wall portion inner end and downward main pipeline of separator aditus laryngis Wall portion junction forms protrusion A, and another side of sidewall portion inner end of separator aditus laryngis and the round wall portion of downward main pipeline are tangent and hand over It connects, interface point B;The walling of flue is composite layer refractory wall;
The angle that the separator aditus laryngis is tubaeform is 20-24 °, and OA lines and OB link groups are angled 60-64 °;
In separator aditus laryngis, the vertical range between wall portion is 800-860mm to protrusion A corresponding thereto;
The composite layer refractory wall includes fire brick layer, thermal insulation concrete layer and aluminosilicate fiberboard layer from the inside to the outside.
The angle that the separator aditus laryngis is tubaeform is 22 °, and the angle of OA lines and OB lines composition is 62 °.
The vertical range of the protrusion A of separator aditus laryngis to the upper wall portions of separator aditus laryngis is 830mm.
Compared with prior art, the utility model has the beneficial effects that:
By in separator flue structure, the rational Design on Plane of separator inlet throat, adjustment entrance shape, increase into Mouthful flow velocity can reach 17m/s or more from device aditus laryngis flue gas flow rate, and the centrifugation of cyclone cylinder rises, and effectively increase point From efficiency, optimal separation effect being realized, increasing circulating ash quantity, the separative efficiency of circulating ash increases substantially.
And walling of flue refractoriness is higher, is hardly damaged during use, need not often go to repair.
Description of the drawings
Fig. 1 is:The utility model front sectional view;
Fig. 2 is:The A-A sectional views of Fig. 1;
Fig. 3 is:The composite layer refractory wall structure partial enlarged drawing of walling of flue.
Reference sign:Flue 1, separator aditus laryngis 101, downward main pipeline 102, upward subtube 103, walling of flue 2, Fire brick layer 3, thermal insulation concrete layer 4, aluminosilicate fiberboard layer 5.
Specific implementation mode
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, but not as to the utility model Restriction.
As shown in Figure 1 to Figure 3, a kind of efficient cyclone flue structure, including flue 1 and walling of flue 2, the flue 1 wrap Include separator aditus laryngis 101, downward main pipeline 102 and upward subtube 103,101 flare of separator aditus laryngis;It is main downwards The central point of 102 cross section of pipeline is O, the side wall portion inner end of separator aditus laryngis 101 and the round wall portion of downward main pipeline 102 Junction forms protrusion A, and another side of sidewall portion inner end of separator aditus laryngis 101 and the round wall portion of downward main pipeline 102 are tangent, simultaneously Handing-over, interface point B;The walling of flue 2 is composite layer refractory wall;
The angle [alpha] that the separator aditus laryngis 101 is tubaeform is 22 °, and OA lines and the angled β of OB link groups are 62 °;
In separator aditus laryngis 101, the vertical range L between wall portion is 830mm to protrusion A corresponding thereto;
The composite layer refractory wall includes fire brick layer 3, thermal insulation concrete layer 4 and aluminosilicate fiberboard layer 5 from the inside to the outside.
Embodiment described above, only one kind of the utility model more preferably specific implementation mode, the skill of this field The usual variations and alternatives that art personnel carry out within the scope of technical solutions of the utility model should all be included in the guarantor of the utility model It protects in range.
