Abstract
The invention relates to a rotating air flow anti-drop wind cap, in particular to a wind cap which is used for a cycle fluidized-bed boiler to uniformly distribute wind. The rotating air flow anti-drop wind cap mainly adopts a wind cap head to connect a connection tube, which is characterized in that: scroll holes are arranged on the wind cap head which is provided with a notch and a stop block; a fixture block is arranged on a connection tube support. The structure of the rotating air flow anti-drop wind cap is simple, compact and reasonable; the wind cap can reduce mutual wash between wind caps and prolong service life, ensure that gas-solid mixing of the hearth is more even and intense to facilitate burning, ensure that the notch on the wind cap head can not return to the position of the fixture block of the connection tube support so that the wind cap head can not drop off.
Description
Technical field
The present invention relates to a kind of swirling eddy defluvium-proof kirtle, specifically be used for CFBB, its effect is an even distributing wind.
Background technology
In prior art, the blast cap head that uses on the CFBB and take between the base and be generally not Welding Structure, but discovery blast cap head in service often comes off, and causes a large amount of bed material to scurry to bellows the blowing out deashing of having to; Another kind is that the blast cap head adopts spot-welded structures with taking over base, and not firm as spot welding, because the unequal factor of being heated still can come off, spot welding is counted too much, and blast cap head wearing and tearing back is difficult to dismounting again when changing.
In addition, the perforate of former blast cap head is radially, wash away mutually between the adjacent blast cap, the blast cap head is very easy to wear, weak point person half a year, the elder just must change about 1 year, not only influenced the long-term stability operation of boiler, and its material is heat-resistance abrasion-resistance alloy, cost an arm and a leg (as a 75t/h CFBB only the blast cap price be about 5～60,000 yuan).
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of swirling eddy defluvium-proof kirtle is provided, can reduce between the blast cap and wash away mutually, can increase the service life; Can make the gas-solid mixing in the thorax more even, strong, help burning.
Main solution of the present invention is achieved in that
The present invention mainly adopts to take over and connects the blast cap head, and feature is to be provided with the scroll hole on the blast cap head; Described blast cap head is provided with breach and block; Described adapter base is provided with fixture block.
Compared with the prior art the present invention has the following advantages:
The present invention is simple in structure, compact, reasonable; Can reduce between the blast cap and wash away mutually, can increase the service life; Can make the gas-solid mixing in the thorax more even, strong, help burning; Can guarantee that breach on the blast cap head can not get back to the position of taking over fixture block on the base, thereby guarantee that the blast cap head can not come off.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is blast cap head perforate figure of the present invention.
Fig. 3 is the location drawing of blast cap assembling of the present invention back breach, block and fixture block.
Fig. 4 arranges front view for blast cap of the present invention on air distribution plate.
Fig. 5 arranges vertical view for blast cap of the present invention on air distribution plate.
The specific embodiment
Following the utility model is further described middle in conjunction with the accompanying drawings embodiment:
The present invention mainly by blast cap head 1, take over 2, scroll hole 3, breach 4, fixture block 5, block 6, air distribution plate 7 and enter air compartment 8 etc. and form.
The present invention adopts and takes over 2 connection blast cap heads 1, is provided with scroll hole 3 on blast cap head 1; Described blast cap head 1 is provided with breach 4 and block 6; Described adapter 2 bases are provided with fixture block 5.
Blast cap head of the present invention 1 scroll hole 3 produces swirling eddy only can rotate the blast cap head to the rightabout of air-flow; Because block 6 and the interaction of taking over the fixture block 5 on 2 bases on the blast cap head 1 just can guarantee that the breach 4 on the blast cap head 1 can not got back to the position of taking over fixture block 5 on 2 bases, thereby guarantee that blast cap head 1 can not come off.
The present invention when mounted, at first will take at 2 and be welded on the air distribution plate 7,, pass the fixture block of taking on 2 bases 5 then with the breach on the blast cap head 14, again along the opposite spin blast cap head 1 of perforate whirlpool direction, until block 6 on the blast cap head 1 with till fixture block 5 on taking over 2 bases contacts.After boiler combustion wind enters air compartment 8, enter blast cap head 1, enter burner hearth by scroll hole 3 then, form vortical flow, reach the purpose of even fluidisation by taking over 2.
