Abstract
The utility model discloses the isobaric air compartment of a kind of CFB garbage burning boiler, comprise the isobaric casing surrounded by crown wall, front wall, Hou Qiang, end wall four pieces of fin panel casings; Isobaric casing end face becomes isobaric air compartment by left and right sidewall enclosed shape; Described crown wall is air distributor structure, is provided with slag-drip opening in the middle of it; Rear wall is provided with air inlet; Crown wall, front wall, Hou Qiang two ends are provided with header; After high before wall of the described end, low dip is arranged; Part crown wall extends out from the header of top and bends downwards, and header that is final and below homonymy is connected to form slag-drip opening.Utilize water-cooling wall to be bent to form cinder notch downwards, broken the restriction of horizontal curved water making pipe, make slag-drip opening bore can according to Demand Design.
Description
Technical field
The utility model relates to a kind of isobaric air compartment for CFB garbage burning boiler.
Background technology
existing CFB burning boiler is applicable to coal and burns.The deslagging of its isobaric air compartment is young, and general direct water cooling tube bends formation to horizontal direction.Because rubbish is different, if house refuse burnt as fuel, the design of slag-drip opening just must expand, and the mode that original dependence water cooling tube level bends is just inapplicable.
Utility model content
For the technical problem of above-mentioned existence, the utility model provides a kind of CFB garbage burning boiler isobaric air compartment, is provided with large-scale slag-drip opening.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: the isobaric air compartment of a kind of CFB garbage burning boiler, comprises the isobaric casing surrounded by crown wall, front wall, Hou Qiang, end wall four pieces of fin panel casings; Isobaric casing end face becomes isobaric air compartment by left and right sidewall enclosed shape; Described crown wall is air distributor structure, is provided with slag-drip opening in the middle of it; Rear wall is provided with air inlet; Crown wall, front wall, Hou Qiang two ends are provided with header; After high before wall of the described end, low dip is arranged; Part crown wall extends out from the header of top and bends downwards, and header that is final and below homonymy is connected to form slag-drip opening.
Improve as one, described isobaric cabinet wall is laid with refractory material.Avoid tubing directly by flue gas or air erosion.
Preferred as one, described slag-drip opening is rectangle and is multiple.Rectangle slag-drip opening is more applicable for the CFB boiler that rubbish is fuel.
Usefulness of the present utility model is: utilize water-cooling wall to be bent to form cinder notch downwards, has broken the restriction of horizontal curved water making pipe, makes slag-drip opening bore can according to Demand Design.And water-cooling wall is connected with upper lower header, keeps water cooling labyrinth, avoid its tube wall temperature too high, cause overtemperature failure phenomenon.And the position of slag-drip opening and number are relative to all better design of traditional mode that bends.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is top view of the present utility model.
Mark in figure: wall, 4 end walls, 5 slag-drip openings, 6 air inlets, 7 headers, 8 sidewalls after 1 front wall, 2 crown walls, 3.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model comprises the isobaric casing surrounded by crown wall 2, front wall 1, rear wall 3, end wall 4 four pieces of fin panel casings; Isobaric cabinet wall is laid with refractory material.Isobaric casing end face is closed by left and right sidewall 8 and is formed isobaric air compartment; Described crown wall 2 is air distributor structure, is provided with slag-drip opening 5 in the middle of it; Rear wall 3 is provided with air inlet 6; Crown wall 2, front wall 1, rear wall 3 two ends are provided with header 7; After high before wall of the described end 3, low dip is arranged; Part crown wall 2 extends out from the header of top and bends downwards, and header 7 that is final and below homonymy is connected to form slag-drip opening 5.Slag-drip opening 5 is rectangle and can for multiple.
Traditional slag-drip opening generation type is that the water cooling tube on crown wall fin panel casing is carried out being bent to form of horizontal direction.Its defect is slag-drip opening cannot to be done too much.And adopt the mode bent by fin panel casing to form slag-drip opening downwards, just not limited.And the fin panel casing after bending is communicated with header, maintains Water-cooling circulating, avoid producing high temperature corrosion.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
