Description
Technical field
The utility model belongs to reactor design technical field, is specifically related to a kind of multiple field filling column type reactor.
Background technology
It is a kind of gas-solid or liquid-solid catalytic reaction device to fill column type reactor, is filled in container using by catalyst granules,
Reaction-ure fluid from reactor one end flow into, in reactor catalyst granules carry out gas-solid, liquid-solid contact, products stream from
The reactor other end flows out.The particles filled consolidation of packed column catalyst reactor, catalyst layer are relatively fixed, also referred to as fixed bed
Reactor is a kind of reactor having many uses, especially has in fields such as petrochemical industry, coal chemical industry, biochemical industry, environmental chemical engineerings
Very extensive application.
Common fixed bed reactors in chemical process, material need the close gap across catalyst, shortcoming
Be exactly long flow path, Flowing Hard, pressure drop is big, load is uneven, be not suitable for the reaction of viscosity higher system particularly.
In order to overcome above-mentioned fixed bed reactors, industrially frequently with radially fed and radially discharging
Radial bed reactor or by horizontal positioned horizontal bed reactor (e.g., Perry R H, the Green D of reactor shell
W.Perry’s Chemical Engineering Handbook–Chemical Reactor.Seventh edition,
Chapter 23.2001, McGraw-Hill.), but effect of this two classes device in terms of resistance is reduced is still extremely limited, together
When will use leptosomatic reactor shape, there are problems that economy and secure context.
If gap increases between catalyst, it is clear that can reduce flow resistance, such as flowing bed reactor is exactly by solid point
It dissipates, be suspended in gaseous state or the reaction medium of liquid, the flowing of gaseous state or liquid reaction medium is hardly influenced by solid.It is right
For polymerisation, with the progress of polymerization, the viscosity of reaction medium constantly increases, and to realize that solid catalyst is situated between in polymerization
Dispersion, suspension in matter are unable to control at all.
Utility model content
The utility model, will be solid using porous filter plate according to fixed bed reactors, the reapective features of flowing bed reactor
Fixed bed is divided into many a catalyst beds by axial, and relocatable solid catalyst particle is filled in each catalyst bed,
The catalyst bed of these segmentations is all equivalent to thermopnore independent one by one.
A kind of multiple field fills column type reactor, including carrying the shell of inlet port and outlet port and in shell
Catalyst bed, the catalyst bed are at least two layers, and each catalyst bed is designed with fixed porous filtering above and below
Plate；Filled solid catalyst granules in each catalyst bed, loading are the 10~90% of catalyst bed layer height.
The upper and lower porous filtering panel aperture of the catalyst bed is less than the grain size of solid catalyst particle, prevents solid
Catalyst passes through porous filter plate.
Preferably, the multiple field packed column reactor catalyst bed is 5~50 layers；Filled solid in catalyst bed
Catalyst granules, loading are the 30~80% of catalyst bed layer height；Reactor feed mouth is under, discharge port is upper.Reaction
The catalyst bed of device is very little, just needs to fill more catalyst in each catalyst bed, pressure drop is caused to increase；Reactor
Catalyst bed it is too many, then can improve reaction kettle cost, increase reactor operation difficulty.
Solid catalyst particle is not filled full in catalyst bed, when reaction solution is flowed from feed inlet toward discharge port,
Solid catalyst particle can float in reaction solution, react faster flow velocity, reaction solution and solid catalyst particle density contrast more
Small catalyst particle floats more apparent；Solid catalyst particle loading is fewer, and catalyst granules gap is bigger under quick condition,
Reaction solution flow resistance is smaller, while catalyst contact surface is reduced, and catalytic efficiency can also decline, so needing suitable catalyst
Loading.
Polysiloxanes, reaction solution are produced for common polymerisation, such as dimethyl siloxane mixed methylcyclosiloxane ring-opening reaction
Viscosity increases with the raising of reaction conversion ratio, and solid catalyst particle floats, and more apparent or even to be tightly attached to upper strata porous
Filter plate gradually reduces solid catalyst particle loading and is conducive to passing through for high viscosity reaction solution, reduces flow resistance.
Further preferably, solid catalyst particle loading gradually reduces the catalyst bed from the bottom up.It can be former
The several layers of loadings in face are identical, followed by successively decreasing, can also gradually successively decrease in proportion.Preferably, catalyst bed is from feed inlet
The solid catalyst particle amount filled toward discharge port is with 10%~30% amplitude taper of catalyst bed layer height.
Preferably, multiple field filling column type reactor can carry out several reactor concatenations, and reactor it
Between supercharging device can be set.
Preferably, the solid catalyst is ion exchange resin, multiple field filling column type reactor is used for two
Methylsiloxane mixed methylcyclosiloxane ring-opening reaction produces polysiloxanes.
Compared with prior art, the utility model has the following advantages that：Reaction solution is filled by multiple field in column type reactor
Multiple catalyst beds, catalyst floats with the flowing of reaction solution, and the pressure drop of entire reactor is very low, is urged so as to fulfill height
Change efficiency, high reaction conversion ratio, uniform mass-and heat-transfer.
