Description
Technical field
The present invention relates to technical field of petrochemical industry, are applied to hydro carbons-producing hydrogen from steam conversion more particularly, to one kind and convert
The boiler tube installing and fixing method of furnace.
Background technique
It is the master of hydrogen needed for hydrogenation plant in petroleum refining process using hydro carbons-steam conversion process hydrogen making
Source is wanted, reburner is the core equipment of such device for producing hydrogen.It is arranged in conversion furnace body in a row through stove roof plate, furnace bottom
The boiler tube of plate, conversion furnace body heat boiler tube, the effect of the catalyst in high temperature and pipe of hydro carbons-steam in boiler tube
Under be cracked into hydrogen, hydrogen is passed through in outlet manifold by boiler tube lower end and is sent out.
Use there are two types of most extensive, most common boiler tube fixed installation modes at present: the first is directly will be under boiler tube
The fixed form that end welds together with outlet manifold；Second is the setting spring fastening support boiler tube at the top of boiler tube, or
It is hung by constant force spring and draws boiler tube or hang boiler tube by the way of pulley weight-adding hammer, make boiler tube in cold conditions in suspention shape
The lower end of state, every boiler tube is connect by the down pigtail pipe mutually welded therewith with outlet manifold.
After converting furnace igniting, the constant temperature of boiler tube and outlet manifold is increased, and temperature is adopted up to 800 degrees Celsius or more
With the boiler tube of the first fixed form it is heated after will not downward prolonged expansion, can only under the traction of hanging mechanism at the top of boiler tube,
The unidirectional thermal expansion elongation of release upwards can push away at this point, generating the thermal expansion elongation in horizontal direction after outlet manifold is heated
Transverse shifting occurs for the dynamic boiler tube welded together therewith, and since outlet manifold is very long, the thermal expansion elongation after being heated is tired
Add, the transverse shifting that the boiler tube in thermal expansion extending direction outermost end generates is maximum, the transverse shifting of boiler tube make boiler tube with
The concentricity of sealing structure is destroyed between conversion furnace body, generates gap therebetween, and then is entered outside air and turned
Change in furnace, influence excess air coefficient in furnace, while radiation loss herein increases, causes to convert furnace thermal efficiency decline.Using
First expansion downwards, discharges thermal expansion portion elongation, reaches thermal expansion after bottom dead center after the boiler tube of two kinds of fixed forms is heated, then
At the top of the boiler tube under the traction of hanging mechanism, then upward prolonged expansion, discharge remaining thermal expansion elongation.And at this point, next part
Thermal expansion elongation in horizontal direction is generated to down pigtail pipe after tracheae is heated, down pigtail pipe is will push and welds therewith
Boiler tube transverse shifting together.Lateral thrust of this load on down pigtail pipe is easy to cause itself and boiler tube, outlet manifold
Weld cracking, due to being connected with high-temperature hydrogen in boiler tube, down pigtail pipe and outlet manifold pipe, there are security risks.
Obviously, all there is not the sealing structure of boiler tube and drop-bottom position in the fixed installation mode of both boiler tubes
Good influence., when cold and hot changes, lateral displacement occurs for boiler tube for the former, and coaxial sealing structure is caused to be destroyed, and influences to turn
Change furnace thermal efficiency；The latter is easy to cause down pigtail pipe and boiler tube, lower gas collection when cold and hot changes again while influencing the thermal efficiency
Pipe weld cracking, there are serious security risks.
Summary of the invention

One end of drop-bottom is extended downwardly in boiler tube, on the suitable position between 1 lower port flange of boiler tube and drop-bottom, is symmetrically welded
There are the securing supports 1.1 being fixedly connected with steel structure of furnace bottom.After installation, it is in boiler tube 1 relative to steel structure of furnace bottom and fixes
State avoids the sealing structure between boiler tube 1 and drop-bottom, is generated displacement because of thermal expansion by boiler tube 1, outlet manifold 4
It influences.
In the present embodiment, securing supports 1.1 are shaft forgings, are symmetrically welded on the two sides of 1 outer wall of boiler tube.Due to conversion
It is the multiple rows of arrangement of boiler tube 1 in furnace body 2, large number of, for the ease of construction, be equipped on steel structure of furnace bottom 3 be used to support it is solid
Determine the channel steel 3.1 of supporting element 1.1, channel steel 3.1 is horizontally set on the two sides of boiler tube 1 in a row.
The fixing means the following steps are included:
Step 1: as shown in Figure 1, 2, more boiler tubes are successively hung in from top to bottom in the conversion respective mounting hole of furnace body 2, and will
Shaft forgings on each boiler tube are placed on channel steel 3.1, are fixed connection by U-bolt, are made each boiler tube can only when heated
Upward prolonged expansion.
For the ease of adjustment, the channel steel 3.1 connecting with U-bolt is equipped with long strip type connecting hole.
Since boiler tube 1 is longer also heavier, most of length, in order to keep the stress balance of boiler tube 1, subtracts on drop-bottom
Power influence caused by sealing structure is covered a while, on the outer tube wall that boiler tube 1 stretches out stove roof plate upwards, is symmetrically welded with a pair of auxiliary
Suspending hang lifting lug 1.2, assisted suspension lifting lug 1.2 by wirerope, fixed pulley with can counterweight weight hang connect.Due to weight
Flexible connection with boiler tube 1 is by wirerope, not only can be such that the stress of boiler tube is balanced, and will not make the balance by
The influence that boiler tube thermal expansion extends.
So far, one end that boiler tube 1 extends downwardly drop-bottom is in stationary state relative to steel structure of furnace bottom 3, and boiler tube 1 can only
The upward prolonged expansion of one direction, the shadow for avoiding the sealing structure between boiler tube 1 and drop-bottom from being subject to because thermal expansion generates displacement
It rings.
Step 2: on the tube wall that boiler tube 1 extends downwardly drop-bottom weld down pigtail pipe 4, the other end of down pigtail pipe 4 with
Horizontal positioned outlet manifold 5 welds, and is connected to boiler tube 1 with outlet manifold 5.
In the present embodiment, the position setting that down pigtail pipe 4 and boiler tube 1 weld securing supports 1.1 and drop-bottom it
Between, in welding procedure, not by the obstruction of channel steel 3.1.
Down pigtail pipe 4 is S-shaped pipe, and has certain elastic deformation ability.In order to guarantee under high temperature operating conditions, weld
Seam will not crack because of thermal expansion stress, and for down pigtail pipe 4 when with boiler tube 1, the welding of outlet manifold 5, down pigtail pipe 4 is along lower gas collection
The opposite direction that 5 expanded by heating of pipe extends is preset with certain twist angle, is extended with offsetting 5 expanded by heating of outlet manifold to lower pigtail
The lateral thrust of pipe 4.
Step 3: the installation sealing structure between boiler tube 1 and conversion 2 mounting hole of furnace body completes boiler tube in hydro carbons-steam
Installation on hydrogen manufacturing conversion furnace.
As a result, the present invention through the above steps, connect boiler tube 1 with steel structure of furnace bottom 3, boiler tube 1 pass through down pigtail pipe 4 and
Outlet manifold 5 connects, and avoids the thermal expansion of outlet manifold 5 and extends the lateral displacement generated to boiler tube 1, can guarantee to the maximum extent
The concentricity of boiler tube and stove roof plate, drop-bottom sealing structure, and then the excess air coefficient in inner flue gas of the stove is reduced, reduce heat dissipation
Loss, improves the thermal efficiency of reburner.And the good elastic deformation of down pigtail pipe 4 itself is utilized, default thermal expansion is passed through
Indemnifying measure, weld cracking caused by avoiding because of thermal expansion, ensure that the safety of production.
