The reformer tube of catalyst filling is set in room, hydrocarbon/steam mixture flows through the reformer tube under high pressure,
Hydrocarbon/steam mixture is subjected to dehydrogenation by means of introducing the heat of combustion chamber.In the case of the reformer with relative high capacity, lead to
Often in a combustion chamber and reformer tube is made to set in a row by reformer tube is vertically-mounted, often row includes multiple pipelines, hydrocarbon/
Vapour mixture preferably flows through the catalyst bed being arranged in reformer tube from top down.Reformer tube passes through combustion
Head cover and the bottom of room are burnt, therefore enters the gas access of reformer tube and leaves the gas vent of reformer tube positioned at combustion
Burn the outside of room.Below the combustion chamber from the process gas gushed out in reformer tube be fed to after processing step.Go out
In the purpose, each relevant collector pipeline is arranged in the vertical end of row's reformer tube below combustion chamber, institute
Collector pipeline is stated to be connected to the row reformer tube and along the row reformer tube extend.Each reformer
Pipeline is connected to collector pipeline by air inlet connector.If there is multiple rows of reformer tube, then being arranged corresponding to number of rows
The number of collector pipeline.Multiple collector pipelines are collected to successively perpendicular to the horizontal-extending removing pipeline of collector pipeline,
All process gas of all reformer tubes merged by collector pipeline can pass through the outlet quilt for removing pipeline
Processing step after being fed into.
Process gas from combustion chamber is at quite high temperature, therefore collector pipeline may be big by process gas
Width heats.This thermal expansion condition as caused by thermal expansion effects for leading to collector pipeline and removing pipeline, therefore collection tube
Change in location of the line relative to reformer tube, and it removes the tie point between pipeline and downstream process equipment and remains substantially solid
It is fixed.This to need to consider collector pipeline by specific design means when accommodating in a combustion chamber reformer tube
By the change in location of thermal initiation, for example, reformer tube is movably contained on the head cover of combustion chamber to compensate because
The variation of position caused by this and mechanical stress.Furthermore, it is possible to the heat accumulation between reformer and collector pipeline, it is thus possible to
High temperature is undesirably established below reformer.Therefore it needs to reduce the level of the heat load as caused by reformer always.
Invention content
The object of the present invention is to provide can realize the means that low thermotropic load level is caused by reformer.
The purpose is realized by the collector pipeline of the feature with claim 1 according to the present invention.The present invention's is excellent
Choosing construction indicates that the preferable configuration can be represented in a manner of separately or combined in all cases in the dependent claims
The aspect of the present invention.
According to the present invention, the receipts of the process gas for removing the reformer being fed by multiple reformer tubes jointly are provided
Storage pipeline, the collector pipeline have：Collector pipeline is used to receive and transport process gas；At least one air inlet
Connector communicated by outlet opening with collector pipeline, and wherein air inlet connector has at least one communicates with outlet opening
First entrance interconnecting piece and at least one second entrance interconnecting piece communicated with outlet opening；First feed line is connected to
One entrance interconnecting piece simultaneously is used to be connected to reformer tube；Second feed line is connected to second entrance interconnecting piece and is used for
It is connected to reformer tube；With the common insulating sheath of variable dimension, the first feed line and the second feed line are surrounded
For thermal insulation.
Particularly, the first feed line and the second feed line can the overwhelming majority extend parallel to each other so that first supplies
Expects pipe line and the second feed line can be coated in especially long section by identical insulating sheath.Insulating sheath can be reduced
To the heat exhaust of environment, coat at least two feed lines using only a common insulating sheath means to compare process gas
Less insulating sheath material is needed the case where each individual feed line is respectively provided with insulating sheath.For example, even
The reformer tube for being connected to the first feed line and the second feed line can be from face of the reformer combustion chamber of collector pipeline
Bottom protrudes, and respectively the mutual distance D between center line is such as 275mm, the first feed line and the second feed line
It can be moved towards each other with distance d between respective center line, the distance d is less than the distance D and is such as 60mm.
Due to the relatively small distance between feed line, it is therefore desirable to which less insulating sheath material surround two feed lines.
Therefore, such region can be formed below row's reformer tube, it in this region can be in two adjacent insulation
Relatively large distance L, especially 0.5D to 1.5D, such as 210mm ± 50mm are provided between sheath, therefore more easily by nature
Convection current is except heat.Therefore, the heat accumulation above collector pipeline and/or below reformer can at least be reduced.
In addition, feed line can be provided with temperature compensation element, the temperature compensation in a particularly simple way
Element can be compensated between cooling inactive state and the operable state of heating air inlet connector and reformer tube it
Between relative position variation.For example, feed line can have arc pipe profile be used as temperature compensation element thus
Increase flexible.Therefore, reformer tube can remain substantially fixed and at most lead in the vertical direction in the horizontal direction
It crosses thermal expansion effects and is subjected to length increase, therefore reformer tube can be contained in the burning of reformer in a manner of fairly easy
In room.Insulating sheath can with the fully variable construction of size therefore its can follow by thermally expanding the temperature compensation caused
The change in location of element and/or deformation.The case where insulating sheath of separation being separately provided with compared to each feed line, jointly
The feed line of insulation has smaller insulating sheath surface.Therefore, the heat-delivery surface of entire insulating sheath reduces, therefore corresponding
Region below the less heat produced to reformer in ground and establish lower temperature.In addition, having compared to each feed line
There is the case where separate insulating sheath, needs are reduced by the common insulating sheath at least two feed lines
Insulating sheath total volume, therefore below reformer exist correspondingly more for air movement free spaces, this has
Help except heat.Meanwhile meaning compared to every using only a common insulation of at least two feed line of insulating sheath pair progress
A feed line is separately provided with the case where insulating sheath of separation needs correspondingly less amount of insulation material.Therefore, each
Feed line must endure as the insulating sheath of corresponding smaller weight ratio, therefore the mechanical stress in feed line can significantly subtract
Less and/or supply line can with more multifibres fine workmanship construct and/or can the construction with more variable dimension to compensate
Thermal expansion effects.Merge to form the first feed line and second of common air inlet connector in common insulating sheath
Feed line can be realized by simple design means causes lower level thermotropic load by reformer, especially because hot
Mechanical stress caused by heat accumulation below expansion effect and/or reformer.
In addition, feed line can extend to be connected to collection by common air inlet connector close to each other
Device pipeline.The air inlet connector that this makes it possible for especially having single outlet hole is via corresponding entrance interconnecting piece to save
The mode of about installation space merges two or more feed lines, and the connector of only one air inlet in this case is connected to collector
Pipeline is to engage multiple feed lines.Therefore the number for the air inlet connector for being connected to collector pipeline can be reduced, and
Also reduce the respective number in the aperture for introducing process gas in collector pipeline.Due to the built-in electrical insulation of collector pipeline
The relatively small perforation of liner can realize the thermal insulation for increasing collector pipeline, therefore can reduce due to from collection tube
Road radiate and caused by reformer lower zone heating.
In addition, by the way that as close to the reformer tube of setting, reformer can have particularly compact structure each other.
Even if in the case that the spacing between reformer tube is narrow, still can by coat two or more feed lines according to
Intermediate space between secondary insulating sleeve ensure reformer bottom part down perpendicular to row's reformer tube and/or perpendicular to
The free convection of collector pipeline.
