Description
Technical field
It the utility model is related to the Sealing Technology at boiler setting wall feed-through pipeline, and in particular to a kind of backplate furnace wall wall pipe
Sealing structure.
Background technology
The heat transmission equipment generally use pipeline of boiler needs pipeline to wear as heating surface, the input and output of its interior media
Cross furnace wall and external connection, during to prevent negative pressure in stove air by it is through walls enter or stove in malleation when flue gas overflow by through walls
Go out, heated pipeline reduces and produced other relevant issues to prevent boiler efficiency through needing to carry out encapsulation process at furnace wall.
Heated pipeline meeting expanded by heating under high-temperature flue gas effect, produces thermal walking, causes the stove with wall pipe junction
Wall is damaged because of longterm expansion inequality by drawing crack, destroys the adiabatic heat insulating effect of furnace wall, causes high-temperature flue gas to reveal, and triggers system
The increase of heat loss and serious potential safety hazard, accordingly ensure that the sealing at place through walls is to ensure the necessary bar of boiler normal operation
Part.
At present, the sealing device generally use metal sealing at backplate furnace wall wall feed-through pipeline, but shape metallic leak-proof structure is complicated,
Installing/dismounting inconvenience, and can not effectively prevent furnace wall and be damaged because expansion is uneven, cause the device sealing poor, short life.
The content of the invention
In order to solve the above technical problems, the utility model provides a kind of backplate furnace wall tube seal structure through walls, it can
Ensure that backplate furnace wall wall pipe freely stretch while expand, do not damage the backplate furnace wall of junction, guarantee sealing thermal insulation effect,
Easy installation and removal, service life are longer.
Its technical scheme is such：A kind of backplate furnace wall tube seal structure through walls, it includes backplate furnace wall and through institute
State the wall pipe of backplate furnace wall, the wall pipe connects wall pipe header, it is characterised in that the wall pipe with it is described
The internal connection binding site of backplate furnace wall, insulation rope is wound with outside the wall pipe, is worn described in the insulation rope sealing
Gap between wall coil and the backplate furnace wall.
It is further characterized by, and is provided with the backplate furnace wall and covers the wall pipe and the wall pipe and collect collection
The seal box of case.
It is fixedly connected between the wall pipe and the insulation rope by binding agent, the insulation rope outside the wall pipe is thick
Spend for 7 to 10 millimeters；
The winding layer length of insulation rope after the winding is more than or equal to the wall pipe with being connected inside the backplate furnace wall
The length at place；
Certain thickness refractory concrete has been poured between the insulation rope and the backplate furnace wall；
The refractory concrete position is disposed with the bar-mat reinforcement of reinforcing；
The seal box is can and fixed with the backplate furnace wall outside weldings, and silicic acid is filled with the seal box
Aluminum fiber minuteness closure material；
The furnace wall backplate includes fire brick layer, insulating brick-layer, perlite flaggy and aluminosilicate fiber cotton layer；
The seal box both sides have through hole, and the through hole outside weldings are provided with expansion joint, the manifold through walls
Collect the through hole and the expansion joint of the header through both sides, the expansion joint end and the wall pipe header outer surface
Fixed welding.
After structure of the present utility model, wall pipe and backplate furnace wall internal connection are wrapped in insulation rope, it is tied
Configuration formula can absorb thermal expansion and the installation offset error of wall pipe all directions, while ensure that wall pipe free wxpansion not
Damage backplate furnace wall；And seal box is covered with outside wall pipe, the sealing at backplate furnace wall wall pipe is further ensured, is improved
The reliability of stable operation of the boiler, and it is simple in construction, installing/dismounting is convenient, service life length.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is seal box outside schematic diagram.
Embodiment
See Fig. 1, shown in Fig. 2, a kind of backplate furnace wall tube seal structure through walls, it includes backplate furnace wall 1 and through backplate stove
The wall pipe 2 of wall 1, wall pipe 2 connect wall pipe header 3, through walls in the internal connection of wall pipe 2 and backplate furnace wall 1
Insulation rope 4 is wound with outside pipe 2, is fixedly connected between wall pipe 2 and insulation rope 4 by binding agent, it is dipped before insulation rope winding
Binding agent, the thickness of insulation rope 4 outside wall pipe 2 is about 8 millimeters, can meet sealing and expansion requirements；The winding of insulation rope 4
Length crosses whole wall pipe 2 and the internal connection of backplate furnace wall 1, further ensures sealing；Insulation rope 4 and backplate furnace wall
Certain thickness refractory concrete 5 is poured between 1, the position of refractory concrete 5 is disposed with the bar-mat reinforcement 6 of reinforcing, further protects
The reliability of sealing structure is demonstrate,proved；The sealing for covering wall pipe 2 and wall pipe header 3 is provided with backplate furnace wall 1
Box 7, seal box 7 is can and fixed with the outside weldings of backplate furnace wall 1, is sealed in seal box 7 filled with aluminosilicate fiber cotton
Material 8, further ensures sealing；Furnace wall backplate 1 include fire brick layer 1-1, insulating brick-layer 1-2, perlite flaggy 1-3 and
Aluminosilicate fiber cotton layer 1-4；Encapsulant is cheap needed for the utility model, and dosage is few, and cost greatly reduces.
