Abstract
The utility model relates to a circulating fluidized bed boiler split type air-hood, comprising an air-hood head and a casing; wherein, the air-hood head and the upper end of the casing are disassembly connected, a plurality of vents are arranged on the walls around the upper end of the casing. During combusting, air enters the coal layer in the furnace chamber through vents on the casing to ensure full combusting and keep the simplest structure of the vulnerable part-air-hood head; when the air-hood head is burned out, only the head needs replacing without the necessity of disassembling other parts. The utility model has the advantages of simple operation, easy maintenance, reducing production cost without affecting production and being a rather ideal split type air-hood at present.
Description
Technical field
The utility model provides a kind of CFBB split blast cap, belongs to boiler combustion accessory technical field.
Background technology
Blast cap is installed on the air distribution plate of CFBB, is used for to coal-fired layer air feed, and be consumable accessory.The blast cap of Ying Yonging mostly is an integral structure in the market, be welded on the air distribution plate after again casting cement fix, in case when blast cap damages, be change or maintenance all pretty troublesome, waste time and energy, influence the normal operation of boiler.At above-mentioned situation, the technology report of at present existing split type blast cap, as Chinese patent communique disclosed utility model patent in 13 days September nineteen ninety-five: boiling boiler dedicated separation formula blast cap, the patent No.: 94224573, removably connect by blast cap head and blast cap body two members and to constitute, air vent is arranged on the blast cap head, is also designing shaft shoulder structure with blast cap head link on the blast cap body.When blast cap burns out, only need blast cap changed first watch and get final product, and need not to tear open other, time saving and energy saving, defective is that air vent is arranged on the blast cap head, blast cap header structure complexity, the cost height, its air feed performance also needs further improvement.
Summary of the invention
The purpose of this utility model provides and a kind ofly can overcome above-mentioned defective, rational in infrastructure, cost is low, service behaviour is good CFBB split blast cap.Specifically:
Comprise blast cap head and sleeve pipe, it is characterized in that: blast cap head and sleeve pipe upper end is for detachably to connect, and the circumferential wall on the sleeve pipe is provided with a plurality of air vents.
Like this in combustion process, wind enters the coal-fired layer of burner hearth from sleeve pipe through air vent, guarantee sufficient combustion, and consumable accessory blast cap head keeps the simplest structure, when it burns out, only need blast cap changed first watch and get final product, and need not to tear open other, simple to operate, easy to maintenance, promptly having reduced cost, do not influenced production again, is present comparatively desirable split type blast cap.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
The specific embodiment
Blast cap head 1 and sleeve pipe 2 upper end thread connection, the circumferential wall of sleeve pipe 2 upper ends is provided with a plurality of air vents 3, is used to coal-fired air feed.Blast cap head 1 keeps the simplest structure, when it burns out, only needs 1 replacing of blast cap head is got final product, and easy to maintenance, cost is low.
