Description
Technical field
The present invention relates to for jointly removing by the collector pipeline of the process gas of the reformer of multiple reformer tube feed, can the process gas of the heat gushed out from reformer be collected by means of described collector pipeline and be fed into further treatment step, such as thus prepare propylene or alkylide by aliphatic hydrocrbon.
Background technology
Reformer for the formal construction of the steam reformer of the catalytic dehydrogenation of hydrocarbon has combustion chamber, the reformer tube of catalyst filling is set in described combustion chamber, hydrocarbon/steam mixture under high pressure flows through described reformer tube, and hydrocarbon/steam mixture stands dehydrogenation by means of the heat introducing combustion chamber.When having the reformer of relative high capacity, usually reformer tube is vertically installed in a combustion chamber and reformer tube is set in a row, multiple pipeline is drawn together in every package, and hydrocarbon/steam mixture preferably flows downward from top by being arranged on the catalyst bed reformer tube.Reformer tube passes top cover and the bottom of combustion chamber, and the gas inlet therefore entering reformer tube and the pneumatic outlet leaving reformer tube are positioned at the outside of combustion chamber.Processing step after the process gas gushed out from reformer tube below combustion chamber is fed to.For this purpose, each relevant collector pipeline is arranged on below combustion chamber in the vertical end of row's reformer tube, and described collector pipeline is connected to described row's reformer tube and extends along described row's reformer tube.Each reformer tube is connected to collector pipeline by air inlet web member.If exist and arrange reformer tube more, the number of collector pipeline is so set corresponding to row.Multiple collector pipeline is collected to the removing pipeline perpendicular to collector pipeline horizontal-extending successively, the processing step after all process gass merged by collector pipeline of all reformer tube can be fed to by the outlet of described removing pipeline.
Under being in quite high temperature from the process gas of combustion chamber, therefore collector pipeline significantly may be heated by process gas.This causes the thermal expansion situation caused by thermal expansion effects of collector pipeline and removing pipeline, and therefore collector pipeline is relative to the change in location of reformer tube, and the tie point removed between pipeline and downstream process equipment remains substantially fixing.This make when reformer tube is held in a combustion chamber needs by specific design means consider collector pipeline by the change in location of thermal initiation, top cover reformer tube being movably contained in combustion chamber such as, compensate the change of position and the mechanical stress therefore caused.In addition, may between reformer and collector pipeline heat accumulation, therefore below reformer, undesirably may set up high temperature.Therefore the level reducing the heat load caused by reformer is needed all the time.
Summary of the invention
The object of this invention is to provide the means that can realize being caused low thermic load level by reformer.
Described object is realized by the collector pipeline with the feature of claim 1 according to the present invention.Preferable configuration of the present invention indicates in the dependent claims, and described preferable configuration can represent aspect of the present invention in mode that is independent or combination in all cases.
According to the present invention, be provided for the collector pipeline of common removing by the process gas of the reformer of multiple reformer tube feed, described collector pipeline has: collector pipeline, and it is for receiving and transporting process gas; At least one air inlet web member, it is communicated with collector pipeline by outlet opening, and wherein air inlet web member has at least one first entrance connection section communicated with outlet opening and at least one second entrance connection section communicated with outlet opening; First feed line, it is connected to the first entrance connection section and for being connected to reformer tube; Second feed line, it is connected to the second entrance connection section and for being connected to reformer tube; With the common insulating sheath of variable dimension, its around the first feed line and the second feed line for thermal isolation.
Especially, the first feed line and the second feed line can the overwhelming majority extend parallel to each other, make the first feed line and the second feed line can insulating sheath by identical in portion's section long especially coated.Insulating sheath can reduce the heat exhaust of process gas to environment, and coated at least two feed lines of insulating sheath that only use one is common mean that the situation having insulating sheath respectively compared to each independent feed line needs less insulating sheath material.For example, the reformer tube being connected to the first feed line and the second feed line can be given prominence to from the reformer bottom of combustion chamber in the face of collector pipeline, and the phase mutual edge distance D separately between medullary ray is such as 275mm, first feed line and the second feed line can move towards each other with distance d between respective medullary ray, and described distance d is less than described distance D and is such as 60mm.Due to the relatively little distance between feed line, less insulating sheath material is therefore needed to come around two feed lines.Therefore, such region can be formed below row's reformer tube, relatively large distance L, particularly 0.5D to 1.5D can be provided between two adjacent insulating sheaths in this region, such as 210mm ± 50mm, therefore more easily by natural convection heat extraction.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 in a particularly simple way, and described temperature compensation element can compensate the relative position change between air inlet web member and reformer tube between the inactive state and the operable state of heating of cooling.For example, feed line can have arc pipe profile increases flexible as temperature compensation element.Therefore, reformer tube can remain substantially fixing in the horizontal direction and in the vertical direction stands length increase by thermal expansion effects at most, and therefore reformer tube can be contained in the combustion chamber of reformer to be quite easy to mode.Insulating sheath can have the fully variable structure of size, and therefore it can follow change in location and/or the distortion of the temperature compensation element caused by thermal expansion.Arrange separately the situation of separative insulating sheath compared to each feed line, the feed line of common insulation has less insulating sheath surface.Therefore, the heat-delivery surface of whole insulating sheath reduces, and therefore correspondingly less heat is distributed to the region below reformer and sets up lower temperature.In addition, there is separately compared to each feed line the situation of independently insulating sheath, by decreasing the insulating sheath cumulative volume of needs for the common insulating sheath of at least two feed lines, therefore below reformer, there is the correspondingly more freeboard for air movement, this contributes to heat extraction.Meanwhile, only use insulating sheath to carry out common insulation at least two feed lines to mean and arrange separately the correspondingly less amount of insulation material of the situation needs of separative insulating sheath compared to each feed line.Therefore, each feed line must bear the insulating sheath of corresponding less part by weight, and the mechanical stress therefore in feed line can significantly reduce and/or supply line can have more multifibres fine workmanship structure and/or can have the structure of variable dimension more thus compensate for heat expansion effect.Merge in common insulating sheath thus form the first feed line of common air inlet web member and the second feed line can realize causing lower level thermic load by reformer by simple design means, particularly due to mechanical stress that the heat accumulation below thermal expansion effects and/or reformer causes.
In addition, feed line can extend close to each other thus can be connected to collector pipeline by common air inlet web member.This makes it possible to use the air inlet web member particularly with single outlet opening to merge two or more feed line via corresponding entrance connection section in the mode of saving installing space, and only an air inlet web member is connected to collector pipeline thus engages multiple feed line in this case.Therefore can reduce the number of the air inlet web member being connected to collector pipeline, and reduce the respective number in the ducted aperture for introducing process gas of collector.Due to the relatively little perforation of the built-in electrical insulation liner of collector pipeline, the thermal isolation increasing collector pipeline can be realized, therefore can reduce the reformer lower zone heating owing to causing from collector heat dissipation of pipeline.
In addition, by the reformer tube of close as far as possible setting each other, reformer can have special compact structure.Even if the spacing between reformer tube is narrow, still can by intermediate space between the insulation thimble successively of coated two or more feed line ensure reformer bottom part down perpendicular to row's reformer tube and/or the natural convection perpendicular to collector pipeline.
As the insulating material of variable dimension, insulating sheath such as can comprise the rock wool and/or glass wool that can support feed line especially.Insulating sheath can have metal level especially, particularly aluminium sheet on the outside of feed line, therefore covers and protects insulating material from environmental influence.Air inlet web member can be soldered to collector pipeline.For this purpose, collector pipeline can have radially outstanding fastening stake especially.Air inlet web member is preferably by steel heat-resisting especially, and particularly high quality steel is made.For example, air inlet web member is made up of austenitic alloy cast steel.The fastening stake can welded with air inlet web member and/or air inlet web member can in be lined with insulating compound, such as concrete, thus the temperature of fastening stake can be kept enough low fastening stake can be such as made up of ferritic steel.Reformer tube is substantially vertically-oriented especially, and gravity direction is observed, and process gas flows downward to the collector pipeline below the combustion chamber being arranged on reformer from top especially on gravity direction.In combustion chamber, the reactant being arranged in reformer tube can react thus formation process gas.Outside at reformer tube, burner can be used to combustion chamber heat supply, thus enough heat can be supplied to carry out the thermo-negative reaction in reformer tube.When the reformer for dehydrogenating propane factory, process gas can be in the temperature of 560 DEG C to 620 DEG C when leaving the combustion chamber of reformer.In order to cleaning purpose, such as, in order to burn settling, reformer tube can be rinsed with clean air, therefore also can set up the temperature of 710 DEG C ± 20 DEG C in the exit of reformer tube.The pressure of such as 8.5bar ± 2bar can be set in collector pipeline.When the reformer for hydrogen and/or ammonia factory, under the pressure of 30bar to 40bar, temperature out can up to 900 DEG C.
Especially, in common insulating sheath, between the first feed line and the second feed line, space is formed.By means of space, the hollow space without the need to filling with insulating sheath material can be formed.This makes more easily to assemble insulating sheath, only needs to be wound around described insulating sheath around at least two feed lines.
Preferably, the first feed line and the elastically bendable thermal expansion arc of each self-forming of the second feed line thus compensate the change of the relative position between the air inlet web member caused by thermal expansion and reformer tube be applied on collector pipeline.When the relative position caused by thermal expansion change between air inlet web member and reformer tube, thermal expansion arc can elastic bending, thus thermal expansion arc can expand according to the degree of thermal expansion or be contracted to greater or lesser scope.Thus, in thermal expansion arc, relatively little change in location can occur, described relatively little change in location can easily be compensated by the insulating sheath of variable dimension.In addition, can two adjacent respectively around at least two feed lines insulating sheath between produce enough spaces, make thermal expansion arc can also pivotable and insulating sheath can not be impinging one another slightly.
Particularly preferably, air inlet web member has the first other entrance connection section communicated with outlet opening and the second other entrance connection section communicated with outlet opening, the first other feed line wherein for being connected to other reformer tube is connected to the first other entrance connection section, and the second other feed line for being connected to other reformer tube is connected to the second other entrance connection section, the common insulating sheath of other variable dimension is wherein set, its around the first other feed line and the second other feed line for thermal isolation, and wherein reformer tube and other reformer tube separate perpendicular to the ducted flow direction of collector.This makes it possible to another row's reformer tube of lateral deviation to be also connected to identical air inlet web member in the same manner.If properly, common insulating sheath can be wound around around all feed lines being connected to air inlet web member in the regional area near air inlet web member.Therefore, close to each other and to be collected in the region of air inlet web member and easily can to provide thermal isolation by independently insulating sheath at the feed line being connected to each row's reformer tube.In this case, in the region that feed line and other feed line extend with different directions due to lateral deviation, at least two feed lines under all situations are only respectively or other feed line provides different insulating sheaths.Other element can be configured and disposed in a similar manner in all cases, particularly configured and disposed symmetrically relative to said elements.
Especially, other air inlet web member is set, it is communicated with collector pipeline by other outlet opening, wherein other air inlet web member has at least one first other entrance connection section communicated with other outlet opening and at least one second other entrance connection section communicated with outlet opening, the first other feed line wherein for being connected to other reformer tube is connected to the first other entrance connection section, and the second other feed line for being connected to other reformer tube is connected to the second other entrance connection section, wherein arrange other variable dimension common insulating sheath its around the first other feed line and the second other feed line for thermal isolation, wherein reformer tube and other reformer tube separate perpendicular to the direction of the flowing by collector pipeline, wherein air inlet web member and other air inlet web member are connected to collector pipeline with departing from the circumferential direction of collector pipeline, and wherein air inlet web member and other air inlet web member are arranged on the common axial height place of collector pipeline substantially especially.This makes another row's reformer tube that also can be connected lateral deviation in the same manner by the air inlet web member of the particularly same configuration be separated.Such region is avoided: i.e. the common axial region of the collector pipeline of feed line and the extension close to each other of other feed line by the air inlet web member departed from circumferential direction.This makes the more easily one side insulating sheath coated feed line another aspect coated other feed line of other insulating sheath, and insulating sheath and other insulating sheath can not disturb in an assembling process impinging one another and/or mutually.Other element in varied situations can be configured and disposed in a similar manner, particularly configured and disposed symmetrically relative to said elements.
Preferably, air inlet web member has inlet pipe, outlet opening is connected to the first entrance connection section and the second entrance connection section by described inlet pipe, wherein arrange between the clamshell of the covering inlet pipe of inlet pipe and air inlet web member insulating compound particularly the reinforcement of concrete in thermal isolation.At least two entrance connection sections can be incorporated into common outlet opening by inlet pipe.In this case, the hollow space of particularly annular can be formed especially and can easily use thermal isolation concrete placement between inner radial inlet pipe and radially outer clamshell.Can remove particularly by the power that the working pressure of process gas produces by clamshell, simultaneously especially insulating compound substantially independent stop heat to be passed to the function of environment via clamshell from process gas.Can also use various types of insulating compound, particularly various types of concrete, it has the temperature profile of different thermal insulation properties for expecting.Especially, the insulating compound with thermal conductivity low especially can be used near entrance connection section, thus when relatively little thermally conductive pathways does not lead to radial outside surface but leads to the end surfaces forming entrance connection section, the thermal isolation of wishing can be realized.Especially when entrance connection section is positioned at bottom on gravity direction, can by concrete placement in clamshell.After the concrete has hardened, air inlet web member can rotate and can be connected to collector pipeline preferably by being welded on gravity direction from top.The fastening stake can welded with air inlet web member can same in be lined with insulating compound, such as concrete, therefore the temperature of fastening stake can be kept enough low fastening stake being such as made up of ferritic steel.
Particularly preferably, collection tube road has liner, described liner by insulating compound particularly concrete formed be used for thermal isolation, and limit collection tube diametrically, wherein intake manifold extends through liner, and described intake manifold is used for the outlet opening of air inlet web member to be connected to collection tube.Can by the metal shell removing of collection tube particularly by the power that the working pressure of process gas produces, insulating compound plays the function stoping heat to be passed to environment via shell from process gas substantially independently especially simultaneously.For example, the process gas in collector pipeline can be in the temperature of 570 DEG C, and the outside of the shell of collector pipeline can be in the temperature of about 160 DEG C.Especially, the inlet pipe forming outlet opening can be pushed into intake manifold, thus easily can enter collection tube through the insulating compound of the liner of collector pipeline by the process gas that air inlet web member is introduced.Intake manifold can make process gas turn to into the direction of specifying of the flowing by collector pipeline especially at least in part.
