Abstract
The utility model provides wearing sleeves of a boiler hood. The inner diameters of the wearing sleeves of the hood are not smaller than the outer diameter of the boiler hood; each two wearing sleeves of the hood are sleeved outside the boiler hood; and a welding rod is welded between each two wearing sleeves of the hood. By virtue of the wearing sleeves of the boiler hood, the problems of poor fluidization quality and passive boiler shutdown caused by damage of the hood in the prior art are solved, and the hood does not need to be replaced. Therefore, the cost is saved, and the maintenance standby time of the boiler is shortened.
Description
Technical field
The utility model belongs to the Wind cap for boiler technical field, relates in particular to a kind of Wind cap for boiler wearing bush.
Background technology
CFBB has the high and low pollution of efficiency of combustion, fuel savings and is convenient to advantages such as adjusting.Yet running time is long will to produce many problems, there particularly have the wearing and tearing of cap head blast cap to leak ash to be serious, often influence fluidization quality, the blast cap life-span is short and change difficult, the each replacing needs to destroy the bed surface cast bed of material, can not start boiler immediately after the replacing, cause user's passive blowing out often, have a strong impact on user's economic benefit.
Summary of the invention
The purpose of this utility model is to provide a kind of Wind cap for boiler wearing bush, has solved prior art because blast cap damages caused fluidization quality variation, the problem of passive blowing out.
The technical scheme that the utility model adopts is: a kind of Wind cap for boiler wearing bush, and the internal diameter of blast cap wearing bush is not less than the external diameter of Wind cap for boiler, and per two blast cap wearing bush are sleeved on the outside of Wind cap for boiler, are welded with welding rod between two blast cap wearing bush.
The beneficial effects of the utility model are: need not to change blast cap, saved cost, and shortened the overhaul reserve time of boiler, guaranteed the boiler safety reliability service.
Description of drawings
Fig. 1 is the front view of the utility model Wind cap for boiler wearing bush;
Fig. 2 is the vertical view of the utility model Wind cap for boiler wearing bush.
Wherein, 1. Wind cap for boiler, 2. blast cap wearing bush.
Specific embodiment
Below in conjunction with the specific embodiment the utility model is elaborated.
A kind of Wind cap for boiler wearing bush shown in Fig. 1～2, the internal diameter of blast cap wearing bush 2 is not less than the external diameter of Wind cap for boiler 1, and per two blast cap wearing bush 2 are sleeved on the outside of Wind cap for boiler 1, are welded with welding rod between two blast cap wearing bush 2.
Behind Wind cap for boiler wearing bush 2 on the outside weldings of Wind cap for boiler 1, in case wearing and tearing occur, only need to change blast cap wearing bush 2, Wind cap for boiler 1 body is not worn, need not to change Wind cap for boiler, saved cost, and the method for this replacement blast cap protective jacket is simple to operation, has saved a large amount of repair times.Therefore, the utility model boiler wear resistant cover has solved prior art because blast cap damages caused fluidization quality variation, the problem of passive blowing out, and need not to change blast cap, save cost, and shortened the overhaul reserve time of boiler.
