Abstract
The utility model relates to a novel detachable wind cap of a circulating fluidized bed boiler. The detachable wind cap comprises a wind cap head and a sleeve, wherein the wind cap head is arranged on the upper end of the sleeve and is connected with the upper end of the sleeve by threads; a plurality of ventilation holes are formed in the circumference wall of the upper end of the sleeve and the wind cap head, respectively; the shape and the diameter of the ventilation holes formed in the wind cap head are the same as these of the ventilation holes in the sleeve; the ventilation holes are formed in a circle form on the wind cap head. Therefore, in the combustion process, wind enters from the sleeve to a coal layer of a hearth through the ventilation holes in the sleeve and the wind cap head, so that the full combustion of coal can be guaranteed; furthermore, a quick-wear part, namely the wind cap head has the simplest structure, and thus the wind cap is easy to operate and convenient to maintain, not only is the cost reduced but also the efficiency is improved, and furthermore, the production is not affected.
Description
Technical field
The utility model is related to a kind of removable blast cap of circulating fluid bed boiler, belongs to boiler combustion accessory technical field.
Background technology
The removable blast cap of New Cycle fluid bed is a kind of blast cap head and sleeve upper end is the device detachably coupled, the circumferential wall of sleeve upper end is provided with multiple air vents, need to only be changed consumable accessory blast cap head so when boiler combustion, without tampering other, it is simple to operate, it is easy to maintenance.The blast cap applied in the market is mostly integral structure, and casting cement is fixed again after being welded on air distribution plate, once when blast cap is damaged, either changing or repairing all pretty troublesome, wastes time and energy, influences the normal operation of boiler.For above-mentioned situation, the report technology of existing split type blast cap at present, the utility model patent as disclosed in 16 days October in 2002 of Chinese patent publication：Split nozzle button for recirculating fluidized-bed boiler, the patent No.：01268947.5, blast cap head is detachably to couple with sleeve upper end, the circumferential wall of sleeve upper end is provided with multiple air vents, wind sleeve pipe, enters coal furnace, construction is simple through air vent in sleeve pipe circumferential wall, convenient disassembly, defect is that air vent is arranged in sleeve pipe circumferential wall, and air feed performance is not enough, needs further improvement.Therefore, develop simple to operate, air feed is sufficient, it is particularly important that lower-cost circulating fluid bed boiler air cap device shows.
The utility model seeks to overcome the shortcomings of existing split type blast cap that there is provided a kind of removable blast cap of New Cycle fluid bed, including blast cap head and sleeve pipe.The Split nozzle button for recirculating fluidized-bed boiler is simple in construction, easy to maintenance, both reduces cost, and does not influence production, is current ideal split type blast cap.
Utility model content
The technical problems to be solved in the utility model is：A kind of removable blast cap of New Cycle fluid bed is provided, blast cap head is with sleeve upper end detachably to couple, and the circumferential wall of sleeve upper end is provided with multiple air vents, and blast cap head is provided with multiple air vents.So in combustion, wind sleeve pipe enters the coal-fired layer of burner hearth through air vent, it is ensured that burning is abundant, and consumable accessory blast cap head keeps simplest structure, simple to operate, easy to maintenance, can both reduce cost, and do not influence production.
In order to solve the above problems, the utility model is realized by following technology.
A kind of removable blast cap of New Cycle fluid bed, including blast cap head and sleeve pipe, blast cap head is with sleeve upper end detachably to couple, and blast cap head is arranged on sleeve upper end, couples with sleeve pipe and blast cap head is provided with multiple air vents；The circumferential wall of sleeve upper end is provided with multiple air vents.Wind enters from sleeve pipe, and the air vent through leading on sleeve pipe and blast cap head enters the coal-fired layer of burner hearth, it is ensured that coal-fired abundant, and consumable accessory blast cap head keeps simplest structure, simple to operate, easy to maintenance, can both reduce cost, and do not influence production.
Blast cap head is arranged on sleeve upper end, and detachable thread connection is used with sleeve pipe.
The circumferential wall of described sleeve upper end is provided with multiple air vents, and air vent is shaped as circle, and a diameter of 50~100mm of air vent.
Air vent is evenly arranged in sleeve pipe circumferential wall in sleeve pipe circumferential wall, and air vent sets 4~8 rows from top to bottom in arrangement is horizontally and vertically facilitated.
The air vent that blast cap head is provided with, ventilation bore dia is identical with ventilation hole shape and diameter on sleeve pipe, and air vent arranges circular on blast cap head.
Above-mentioned technical proposal is employed, the beneficial effects of the utility model are：
Blast cap head is detachably to couple with sleeve upper end, it is simple in construction, when blast cap head is burnt out, blast cap head need to only be changed, it is easy to maintenance, multiple air vents are provided with the circumferential wall of sleeve upper end with blast cap head, wind enters the coal-fired layer of burner hearth from sleeve pipe through air vent, it ensure that fire coal fully, service behaviour is good.
Therefore, circulating heat pump boiler split blast cap has the prominent advantages that with existing split type blast cap：（1）Blast cap head is detachably to couple with sleeve upper end, rational in infrastructure, easy to maintenance, low cost,（2）The circumferential wall of sleeve upper end is provided with multiple air vents, and wind enters the coal-fired layer of burner hearth from sleeve pipe through air vent, and service behaviour is good, improves production efficiency,（3）Blast cap head is provided with multiple air vents, further ensures air feed abundance, and service behaviour is good.
The Split nozzle button for recirculating fluidized-bed boiler that the utility model is provided, it is simpler in structure, more facilitate for the maintenance of consumable accessory blast cap head, reduce cost, production efficiency is improved, provides and greatly facilitates for practical application, can be widely applied to the industrial operations such as boiler.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model
1 blast cap head in accompanying drawing；Ventilating opening on 2 sleeve pipes；3 sleeve pipes；Air vent on 4 blast cap heads
Embodiment
Blast cap first 1 couples with the threaded upper ends of sleeve pipe 3, convenient disassembly, is provided with multiple air vents in the circumferential wall of the upper end of sleeve pipe 3 with blast cap head, and wind enters from sleeve pipe, enters coal furnace by the air vent on sleeve pipe and blast cap head, it is ensured that coal-fired air feed.Blast cap first 1 keeps simplest structure, when it burns out, and need to only change blast cap first 1, is not required to repair sleeve pipe, therefore easy to maintenance, low cost, functional performance is good, and production efficiency is high.
