Description
The present invention relates to a kind of reactor assemblies that has a kind of contact tube bundle; By two or more reactors that are close to the reactor assemblies manufacturing of arrangement; With a kind of reactor assemblies or reactor as carrying out the application of oxidation reaction.
Form by a hydrostatic column according to the reactor that general reactive species is made, wherein settle a kind of tube bank of forming by a large amount of common vertically arranged contact tubes.These contact tubes optionally are loaded with catalyst, and their pipe end is in pipe end sealing and fixing and flow to a calotte that is connected with container in last terminal or time terminal.Input or output the reactant mixture that flows through contact tube by these calottes.Space guiding heat exchanging agent circulation by around contact tube its objective is balanced thermal balance, especially when the reaction with strong fuel factor.
Because economic cause is used the reactor have contact tube as much as possible, the number of wherein settling contact tube is in 10000 to 40000 scope (referenced patent DE-A-4431949) usually.
Consider the even distribution of process, transportation, installation and reaction technology, particularly cooling medium, reach reactor diameter and the technology upper limit of the pipe number that determines thus.Because gasiform reactant all is the direct draught work that is in usually, in the reaction vessel bottom and particularly to constitute the cap on reaction air chamber border be the semicircle form on top.Concerning this cap, prerequisite is a kind of cylindrical reactor structure of requirement.
But the shortcoming of columned reactor is, the air-flow that technical favourable heat exchanging agent laterally leads to contact tube leads to the inner space of the contactless pipe of reactor from the contact tube perimeter, owing to radially inwardly reduce consumingly, can not be transported to whole cooling mediums contact tube bundle inside.Must axially export cooling medium by the perforation in guide plate or rather, could guarantee that like this pressure loss and pump power remain in the acceptable boundary.
The objective of the invention is to make heat exchanging agent to pass through reactor section consistently.
The invention provides a kind of reactor, its production capacity can satisfy the requirement of individual cases.
Solution of the present invention is the reactor assemblies that has a contact tube bundle, and the input pipe or the efferent duct that are used in two ends of reactor assemblies guide a kind of heat exchanging agent circulation by the space around contact tube; Carry crossflow to contact tube with one or more pumps by the faucal that inputs or outputs heat exchange system, carry heat exchanging agent or portion of hot replacement fluids by one or more heat exchangers that are placed on the outside in case of necessity, heat exchanging agent leads to pump or pump group by following pipeline input with by upper pipe herein.This programme is characterised in that reactor assemblies has a rectangular cross section.
The cap that limits the reaction air chamber of direct draught work among the present invention is semi-cylindrical, and it is necessary as it the both sides of the reactor that has rectangular cross section being defined.
It is favourable on two relative reactor sides that are parallel to contact tube contactless pipe chamber being set in space reactor, and preferably it extends to the height of whole reactor; With one or more guide plates are set, it alternately is separated out the room on the passage section of contactless pipe chamber.By this arrangement the heat exchanging agent fluid is carried equably in the desired manner around contact tube.
Preferably contactless pipe chamber is arranged on two broad side surfaces of reactor.
About the ratio of reactor assemblies length and width is 1: 1 to 10: 1st, favourable, preferred 3: 1 to 6: 1, more preferably 5: 1.The height of preferred reactor is 1.5m to 7m.
The number of preferred regulation guide plate is an odd number, causes input and output heat exchanging agent the same side at reactor assemblies thus.More preferably regulation guide plate number is 1,3 or 5.
Pump or pump group and be placed on outside heat exchanger in case of necessity to be arranged in reactor assemblies the same side be favourable preferably are placed on broad side surface.Therefore reach special saving space.
Because different courses of reaction can require different heat distributions.With one or more branch roads that caused in territory, no area under control by guide plate, the reach through hole with fixing or adjustable throttle amount satisfies the requirement under the individual cases.
A kind of preferred form of implementation is that reactor assemblies is provided with partition wall in the input and output pipeline, it in input channel, constituted one down outside cup and one down inner cup and in output channel, constituted on inner cup on outside cup and.Heat exchanging agent flows out from down outside cup, flow into upward inner cup by one between input pipe and efferent duct zone, enter reaction compartment by its through hole around contact tube, pass through the through hole of inner cup down subsequently, enter outside cup by the zone between input pipe and the efferent duct, turn back to pump or pump group by efferent duct at last.Can not change common pump spread pattern thus, it might carry heat exchanging agent and hybrid reaction gas by the direct current mode of movement.
Under the situation of reactor with the direct current mode of movement, for reaching the coupling with desired Temperature Distribution, be by leaning against a mistress corresponding to the wide side of reactor of contactless tube space, this mistress have lead to around the opening of the space reactor of contact tube bundle and have fixing or adjustable through hole be used for outside indoor heat exchanging agent.
The relative dislocation of the contact tube of contact tube bundle is arranged, transverse to the pipe of heat exchanging agent airflow direction apart from S
qWith longitudinally to the pipe of heat exchanging agent airflow direction apart from S
lRatio be preferably greater than or equal
More preferably equal
This conduit arrangements mode makes the heat exchanging agent of circulation cause less resistance, and correspondingly under the higher coefficient of heat conduction, the pressure loss is less.
Another theme of the present invention is a reactor, and it is made up of reactor assemblies two or more, be close to arrangement mutually along the reactor long axis direction, on narrow limit.This reactor has been characterised in that production capacity flexibly, and it can satisfy various concrete requirements.The arrangement that the semicircle of capping air chamber block can be close to mutually by the narrow limit of reactor assemblies prolongs flat side, and it correspondingly is provided with through hole.Improve the upper limit of reactor production capacity thus.
Heat exchanging agent circulation can be served the heat of deriving in the hybrid reaction gas that flows through contact tube, but similarly also transfer heat give the hybrid reaction gas that flows through contact tube.Reactor assemblies of the present invention or reactor of the present invention can be used in exothermic reaction, also can be used in the endothermic reaction.It is particularly useful for carrying out in the reactor of oxidation reaction, is used in particular for producing phthalic acid, maleic anhydride, glyoxal, (methyl) methacrylaldehyde or (methyl) acrylic acid.
The present invention is described in further detail below in conjunction with drawings and Examples.
