Description
Technical field：
It the utility model is related to a kind of harp type heating furnace.
Background technology：
In petroleum chemical industry, continuous reformer is mainly used to produce premium-type gasoline or provides high quality for downstream
Work raw material, China have built tens sets of reformers on the basis of using various technology in recent years.Used in device
Reaction feed heating furnace (Four in one furnace), due to requiring low media pressure drop, reaction feed is generally only
Heated in radiation chamber, radiation comb is also using the " u "-shaped comb connected by inlet and outlet concetrated pipe.Wherein positive " u "-shaped comb adds
Hot stove using at most, take second place by inverted " u "-shaped comb heating furnace use.
The most commonly used type of reactor of industry is to go out type on enterprising at present, and corresponding matched heating furnace is on enterprising
The Four in one furnace of the positive " u "-shaped comb gone out.It is such it is enterprising on go out the combination of reactor-just U-shaped comb heating furnace and also can
Make connecting pipeline moves towards reasonable.
Industry is upper entering and lower leaving type using more than second type of reactor at present, matched heating furnace be generally under into
Under the inverted " u "-shaped comb that goes out.In such combination, the reaction medium after the heating come out from heating furnace bottom is, it is necessary to again
Climb to reactor head.Therefore, under such a combination exterior tubing design, be frequently accompanied by larger pipeline stress, it is necessary to
Multiple turnings are artificially set, artificially lengthen length of pipeline to absorb expansion, solve stress problem.It is inclined to ultimately result in pipeline investment
Greatly, the pressure drop of pipeline is also corresponding higher.
Utility model content：
The purpose of this utility model is to provide a kind of harp type heating furnace, it is characterized in that, setting 4 is relatively independent in furnace body
Burner hearth；Each burner hearth bottom inlet porting concetrated pipe；More furnace tubings are set in burner hearth, and furnace tubing is vertical in burner hearth
Come together in upwards in the outlet header of roof of the furnace.
The furnace tubing is in harp type straight up and down.
The lower space arrangement combustion air hot-flow flue of the inlet manifold.
Material in the outlet header of roof of the furnace out enters the entrance of reactor head through connecting pipeline nearby；Instead
The reaction mass for answering device outlet at bottom to come out, enters the inlet manifold of burner hearth bottom through connecting pipeline nearby.
The beneficial effects of the utility model are：
It is rational in infrastructure, it is easy to use, have the advantages that pressure drop is low, reduced investment, when it combines with the reactor of upper entering and lower leaving
In use, can more optimize device pipeline designs, bring outside pipeline investment saving, moreover it is possible to reduce full device pressure drop, optimize device
Processing performance and overall economy quality.

Embodiment
Attached drawing 1, is a specific embodiment of the utility model.The harp arrangement reform Four in one furnace mainly by
The part such as radiation chamber, convection cell forms, and wherein radiation chamber includes 4 relatively independent burner hearths, and each burner hearth heating is a kind of anti-
Answer medium.Every kind of reaction medium is introduced by the inlet manifold 1-2 for being located at furnace bottom, and then distribution enters the harp flowed up
Formula comb 1-4, for comb after the heating of burner 1-3 double-side radiations, the medium after heating enters the outlet header 1-5 of furnace roof
In, it is then out reactor inlet.
The piping being made of inlet manifold 1-2, harp type comb 1-4, outlet header 1-5, is hanged by suspention spring 1-6
Hang on the steel construction of radiation top.Whole piping can free wxpansion, and form system together with reactor, entrance piping, outlet piping
One expansion absorption, suspension strut system.
Convection cell 1-7 is seated the top of radiation chamber, can set conventional system of steaming, and it is empty can also to heat burning
Gas or/and depentanizer reboiling medium etc..The different of convection cell bringing-up section set the right for not influencing the utility model.
Attached drawing 2 is harp arrangement type Four in one furnace and upper entering and lower leaving reactor combined layout schematic diagram.Reactor outlet
Medium enter the inlet manifold of heating furnace bottom through connecting pipeline, from going out at the top of heating furnace after the heating of harp type comb
Mouth concetrated pipe outflow, and the connecting pipeline through top enters next stage reactor inlet.
Harp type comb 2-4 in attached drawing 2, the group together with suction line, outlet line, upper intake lower outlet type reactor 2-1
Into unified expansion absorption, suspension strut system.Wherein, furnace outlet concetrated pipe hangs on heating furnace steel knot with pendulum spring
On structure, inlet and outlet concetrated pipe separately sets guiding, spacing facility.
The one of harp type Four in one furnace and upper entering and lower leaving is anti-, two anti-, three anti-, four anti-and plate heat exchanger combines cloth
Put, can significantly shorten connecting pipeline, reduce horizontal layout and take up an area, reduce the overall presure drop in pipeline.
Four in one furnace described in the utility model, corresponding to 4 reactors of reforming reaction.According to reforming process
Difference, it is also possible to using three reactors, three-in-one heating furnace, or five reactors, five in one heating furnace.Radiant box
Or the specific number of reactor, have no effect on the technical thought of the utility model.
Pendulum spring shown in attached drawing 2, can be set according to pipeline stress calculating results and specific CONSTRUCTED SPECIFICATION
For constant force spring, variable spring or balance weight etc..These details have no effect on the technical thought of the utility model.
The position suspending in midair, is spacing, supporting drawn in attached drawing 2 and quantity etc., only as explanation the utility model
Thinking and it is exemplary, can be adjusted in the project implementation process depending on specific deployment scenarios and pipeline stress calculating results and excellent
Change, its result has no effect on the general technical thinking of the utility model.
It should be appreciated that above-mentioned example is only to illustrate the technical concepts and features of the utility model, its object is to for ability
Field technique personnel understand the content of the utility model and accordingly decision implement, and are not the exhaustion of embodiment, it is impossible to
