The utility model provides a: a circulating fluidized bed boiler, includes air distribute device, air distribute device includes air distribution plate, tuber pipe and bell hood head, the one end fixed connection of tuber pipe is on the air distribution plate, another pot head of tuber pipe is equipped with bell hood head, bell hood is overhead has seted up a plurality of ventholes, the tuber pipe is close to the one end of bell hood head and has seted up L shape fixed slot, L shape fixed slot includes along the insertion section of tuber pipe axial setting and the canned paragraph that sets up along tuber pipe circumference, be provided with the fixed block on the inner wall of bell hood head, the fixed block can slip into and get into the canned paragraph along insertion section. The utility model provides a scheme prior art the cost is reduced that compares to tuber pipe and hood head are connected more stably, and easy dismounting is quick.
Description
Technical field
The utility model relates to boiler technology field, particularly a kind of CFBB.
Background technology
Current Technology of Circulating Fluidized Bed Boiler is rapidly developed, and boiler grid plate installs and uses a large amount of air-distribution device.CFBB organizes burning of coal based on circulating fluidization principle, to carry a large amount of high-temperature solid particle circulating combustion for key character, enough speed, strength and stiffness must be had from furnace bottom air-distribution device First air air-flow out, while support solid particle, produce strong disturbance, to ensure that bed material is in fluidized state all the time, organize and burn normally.
Air-distribution device (i.e. blast cap) conventional in prior art has multiple, as " 7 " font blast cap, welded type bell-shaped blast cap, mushroom-shaped blast cap etc.There is self serious wear and air distribution plate and leak slag serious problems in " 7 " font blast cap, it is effective that solder type bell jar blast cap prevents air distribution plate from leaking slag, but after there is long-play or furnace wall cooling leak after in blast cap hole accumulated slag should not clear up problem.The patent No. is that the utility model patent of 201420528962.X discloses and a kind ofly adopts bell blast cap head, it is easy for installation and removal thus easy cleaning, but because blast cap head itself with just adopt air-tightness to offset between airduct to be connected, cause the stability connected not to be fine, make blast cap head there is the risk come off.
Utility model content
For the deficiency that prior art exists, main purpose of the present utility model is that providing a kind of blast cap head and airduct to stablize is connected and the CFBB of easy disassembly.
For achieving the above object, the utility model provides following technical scheme: a kind of CFBB, comprise air-distribution device, described air-distribution device comprises air distribution plate, airduct and bell blast cap head, one end of described airduct is fixedly connected on air distribution plate, the other end of described airduct is arranged with bell blast cap head, described bell blast cap head offers multiple venthole, described airduct offers L shape holddown groove near one end of bell blast cap head, described L shape holddown groove comprises the inserting paragraph axially arranged along airduct and the canned paragraph arranged along airduct circumference, the inwall of described bell blast cap head is provided with fixed block, described fixed block can slip into along inserting paragraph and enter canned paragraph.
Preferably, the outer surface of described bell blast cap head is provided with wearing layer.
Preferably, described multiple venthole circularizes structure spaced set.
Preferably, the shape of the shape of described fixed block and size and canned paragraph and size identical.
The utility model has the following advantages relative to prior art tool, the utility model does not need on airduct, to arrange supporting plate and arrange balancing weight on bell blast cap head, cost decreases, as long as and the inserting paragraph of the fixed block of bell blast cap head along L shape holddown groove is slipped into, and then rotate bell blast cap head, make fixed block enter canned paragraph can realize installing, convenient and swift, when dismantling, step is contrary.Compare prior art, because the coordinating of canned paragraph and fixed block, bell blast cap head is difficult to be come off by jack-up causing, so the connective stability of airduct and bell blast cap head is more reliable.Fast more convenient when mounting and dismounting, meet the demand of cleaning air-distribution device fast.
Accompanying drawing explanation
Fig. 1 is the sectional view of the air-distribution device of a kind of CFBB of the present utility model;
Fig. 2 is the structural representation of airduct of the present utility model and bell blast cap head.
In figure: 1, air distribution plate; 2, airduct; 4, L shape holddown groove; 5, inserting paragraph; 6, canned paragraph; 7, bell blast cap head; 8, fixed block; 9, venthole.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of CFBB, comprise air-distribution device, air-distribution device comprises air distribution plate 1, airduct 2 and bell blast cap head 7, one end of airduct 2 is fixedly connected on air distribution plate 1, the other end of airduct 2 is arranged with bell blast cap head 7, bell blast cap head 7 offers multiple venthole 9, airduct 2 offers L shape holddown groove 4 near one end of blast cap head 7, L shape holddown groove 4 comprises the inserting paragraph 5 axially arranged along airduct 2 and the canned paragraph 6 arranged along airduct 2 circumference, the inwall of bell blast cap head 7 is provided with fixed block 8, fixed block 8 can slip into along inserting paragraph 5 and enter canned paragraph 6.The utility model does not need on airduct 2, to arrange supporting plate and arrange balancing weight on bell blast cap head 7, cost decreases, as long as and the fixed block 8 of bell blast cap head 7 is slipped into along disclosing of L shape holddown groove 4 into section 5, and then rotate bell blast cap head 7, make fixed block 8 enter canned paragraph 6 can realize installing, convenient and swift, when dismantling, step is contrary.Compare prior art, because the coordinating of canned paragraph 6 and fixed block 8, fixed block 8 and canned paragraph 6 are mutually to establishing, and bell blast cap head 7 is difficult to be come off by jack-up causing, so airduct 2 is more reliable with the connective stability of bell blast cap head 7.Fast more convenient when mounting and dismounting, meet the demand of cleaning air-distribution device fast.
In addition, in order to increase the service life of bell blast cap head 7, the outer surface of bell blast cap head 7 is provided with wearing layer.
Wherein multiple venthole 9 circularizes structure spaced set, and the air-out of bell like this blast cap head 7 can be more even, is conducive to the raising of the efficiency of combustion of recirculating fluidized bed.
In the utility model the shape of the shape of fixed block 8 and size and canned paragraph 6 and size identical, the benefit of such setting is, fixed block 8 and the surface of canned paragraph 6 can be good laminating, decrease bell blast cap head 7 and operationally produce and rock, make the air-out that bell blast cap head 7 can be good.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
