Abstract
For an anti-laying dust blast cap for CFBB, it is characterized in that: be made up of interior pipe (11), wind scooper (10), support column (15); Interior pipe (11) top closure; The profile that wind scooper (10) is is remove the hollow cone dress body at top; Wind scooper (10) is coaxial with interior pipe (11); Wind scooper (10) has wind-guiding gap (13) between inner surface and inner tube outer surface; The position that interior pipe (11) sidewall is corresponding with wind scooper (10) has horn-like pore (14), and one end of horn-like pore (14) big uncork is near wind scooper (10), and one end of horn-like pore (14) little opening inwardly; Support column (15) one end is connected with interior pipe (11) outer surface, and support column (15) other end is connected with wind scooper (11) inner surface.The utility model can reduce the blast cap laying dust of CFBB.
Description
Technical field
The invention belongs to boiler appliances, particularly relate to a kind of anti-laying dust blast cap for CFBB.
Background technology
Blast cap is the vitals of CFBB, and existing blast cap faces the problem of sinking, and will remove cleaning at set intervals, very waste of manpower, delays production.
Summary of the invention
The object of the invention is to propose a kind of anti-laying dust blast cap for CFBB for the deficiencies in the prior art.
The present invention possesses skills content:
1, for an anti-laying dust blast cap for CFBB, it is characterized in that: be made up of interior pipe (11), wind scooper (10), support column (15); Interior pipe (11) top closure; The profile that wind scooper (10) is is remove the hollow cone dress body at top; Wind scooper (10) is coaxial with interior pipe (11); Wind scooper (10) has wind-guiding gap (13) between inner surface and inner tube outer surface; The position that interior pipe (11) sidewall is corresponding with wind scooper (10) has horn-like pore (14), and one end of horn-like pore (14) big uncork is near wind scooper (10), and one end of horn-like pore (14) little opening inwardly; Horn-like pore (14) and wind scooper (10) surperficial angle (16) are greater than 105 degree and are less than 145 degree; Support column (15) one end is connected with interior pipe (11) outer surface, and support column (15) other end is connected with wind scooper (11) inner surface.
2, a kind of anti-laying dust blast cap for CFBB as described in technology contents 1, is characterized in that: described horn-like pore (14) is circular hole, square hole, bellmouth.
3, a kind of anti-laying dust blast cap for CFBB as described in technology contents 1, is characterized in that: the top of described support column (15) has chamfering.
4, a kind of anti-laying dust blast cap for CFBB as described in technology contents 1, is characterized in that: the top of described interior pipe (10) is coniform pinnacle, streamlined pinnacle.
Technology contents illustrates and beneficial effect:
Technology contents illustrates 1: as described in technology contents 1, main concept of the present invention is: adopt horn-like pore (14) to reduce the laying dust blocking of interior pipe (10), wind scooper (11) is adopted to prevent the close-burning near horn-like pore (14) of the coal dust in outer gas stream, conical ring shape wind-guiding air gap (13) between wind scooper (11), tubing string (10) can prevent from occurring eddy current near horn-like pore (14), eddy current is the key area of coal dust close-burning, and the eddy current reduced near blast cap is conducive to reducing close-burning, laying dust; The effect of support column (15) supports wind scooper (11).
Technology contents illustrates 2: technology contents 2 is preferred versions of the present invention; Circular hole, discharge hole, bellmouth are easily processed.
Technology contents illustrates 3: technology contents 3 is preferred versions of the present invention; Chamfering can be conducive to reducing the eddy current near support column.
Technology contents illustrates 4: technology contents 4 is preferred versions of the present invention; Coniform pinnacle, streamlined pinnacle can prevent interior pipe top from occurring eddy current.
Words and phrases are explained: horn-like, refer to that one end cross-sectional area is greater than the cavity of the cross-sectional area of the other end; .
Practicality of the present invention is: the present invention can reduce the blast cap laying dust of CFBB.

Detailed description of the invention:
Below in conjunction with embodiment, embodiments of the present invention are described:
Embodiment 1:
As shown in accompanying drawing 1-5, embodiment 1 is made up of interior pipe 11, wind scooper 10, support column 15; Interior pipe 11 top closure; The profile that wind scooper 10 is is remove the hollow cone dress body at top; Wind scooper 10 is coaxial with interior pipe 11; Wind-guiding gap 13 is had between wind scooper 10 inner surface and inner tube outer surface; The position that interior pipe 11 sidewall is corresponding with wind scooper 10 has horn-like square hole 14, and one end of horn-like square hole 14 big uncork is near wind scooper 10, and one end of the little opening of horn-like square hole 14 inwardly; Horn-like square hole 14 and wind scooper 10 surperficial angle 16 degree of equaling; Support column 15 one end is connected with interior pipe 11 outer surface, and support column 15 other end is connected with wind scooper 11 inner surface; In order to the air-flow of side that facilitated Fig. 5 only to draw of stating.
Embodiment 2, as shown in Figure 6, the interior pipe of this embodiment has coniform pinnacle, and other and embodiment 1 are similar.
