Description
Technical field
The present invention relates to boiler seal fields, in particular to boiler top flexible seal device and its construction method.
Background technique
Pulverized-coal fired boiler flexible sealing is key position in entire boiler operatiopn, and is easiest to occur leaking out, leaks ash, is scattered
Heat, the boiler roof sealing of existing boiler be usually in a manner of physical seal based on, (place such as through walls can use the sealing of bottom steel plate
Steel plate structure of seal box), then sealed with hard materials such as refractory mortar, castable refractory, insulated pouring material, then use semi-rigid
Rock wool board, rock wool or silicate aluminum board, aluminium silicate wool, pasted with binder, or whole plaster again with wire netting, with flame retardant coating.
If there is the Vibration Condition under the condition of high temperature after boiler puts into operation, it can make to deform after hard steel plate is heated, lead to refractory material
And semi hard insulating material cracking, shelling, cause to leak cigarette due to that can not restore to the original state during boiler fortune is stopped, leak ash, scattered
The problems such as hot, can not only reduce boiler thermal efficiency, and the dust flown upward influences production environment；In addition, top dust stratification overtemperature,
Difficulty can be brought to the maintenance of normal boiler maintenance.
Current sealing device structure as notification number be CN207471578U disclosed in patent, including it is ceiling, through walls
Pipe and fixation steel plate, ceiling are made of roof tube and ceiling floor, are tightly connected at the top of ceiling and boiler, and fixation steel plate is tightly connected
On ceiling；Be sealedly connected with metal sealing box on fixation steel plate, wall pipe sequentially pass through the top surface of ceiling and fixation steel plate with
And the top surface center of metal sealing box, the outer surface of metal sealing box was laid with flexible seal device around wall pipe one week, flexible
Sealing device includes ceramic fibre sealant, and ceramic fibre sealant is made of ceramic fibre and high temperature binder.
But there is no direct connection, ceramic fibre sealants to be easy to happen phase for current steel mesh and ceramic fibre sealant
To movement, causes it to be easy ceramic fibre sealant and be easy to happen damage.
Summary of the invention
In view of the deficienciess of the prior art, the first object of the present invention is to provide a kind of boiler top flexible sealing dress
