Using slurry bed system as mentality of designing, the paste state bed reactor constitutes reactor shell by standard device flange cylinder, including：Reducing housing, upper low head, the bottom inflow mouth of pipe, top gas outlet, slurry inlet and serum outlet；Within the housing with lower component：Inner draft tube, coil heat exchanger, gas clamping plate distributor, riser, redistributor and cyclone separator.Gas uniformly sprays through clamping plate distributor, reacted with the catalyst slurry in reactor enclosure body, flowed out in reactor upper end after gas-liquid separation from gas vent, slurries at free surface, toward flowing down, up flow with gas reaction and circulated out of guide shell again from the side outflow of guide shell bottom.Paste state bed reactor of the present invention carries out matched design to slurry bed system, reaches efficient interior circulation effect by analyzing flow.
Description
Technical field
The invention belongs to field of chemical equipment, it is related to the reactor for gas-liquid two-phase or gas-liquid-solid phase reaction, such as gas
The gas-liquid-solid three-phase paste state bed reactor of liquid reactor, fischer-tropsch synthesis process.
Background technology
Gas-liquid reactor is fairly simple, and mentality of designing is used as using gas-liquid-solid three-phase paste state bed reactor.
Slurry bed system is the focus of reactor development in recent years, and its major advantage is：For mixing, heat recovery, temperature control
System is provided than larger flexibility, and can apply finely grained catalyst, interior diffusion effect is become minimum.Paste state bed reactor
The power source of reaction mixing is used the syngas as, catalyst is suspended and reacted in the liquid phase；Because no machinery is stirred
Mix, thus No leakage can run under high pressure.But this kind of reactor has axial backmixing, its feed stock conversion is relatively low, liquid
Body hold-up is big, it is possible to create obvious homogeneous diffusion, and to gaseous reactant, it is also possible to obvious resistance to mass tranfer is produced, is dropped
Low total reaction rate.
In the design of reactor, it should according to specific course of reaction, the property, main anti-of reaction raw materials is considered
The separation of hydrodynamics, product in the characteristics of answering, reactor and many factors, the type of reasonable selection reactor such as refined
Formula, optimizes structure of reactor.
Patent about paste state bed reactor is simultaneously few, respectively there is feature.Existing slurry bed system design and imperfection, some are excessively
Complexity, some do not reach the effect of reaction matching simply excessively.And larger difficulty is also there is in terms of amplification.
The content of the invention
By analyzing principle and the flow field of paste state bed reactor, a kind of new and effective paste state bed reactor is have devised,
The reactor constitutes reactor shell by standard device flange cylinder（5）, including：Reducing housing (12), upper low head
（14、2）, the bottom inflow mouth of pipe（1）, top gas outlet（15）, slurry inlet（16）And serum outlet（4）.Efficient slurry bed system
Reactor is designed, the part within the housing：Gas clamping plate distributor（3）, inner draft tube (6), riser（7）, coil pipe changes
Hot device (8 and 10), redistributor（9）, tooth form is by liquid mouthful（11）And cyclone separator（13）.
A kind of design of new distributor is proposed, the distributor is formed by upper lower plate and leakproof bead clamping, realized
The equally distributed function of slurry bed system anti-clogging leakproof and gas.
A kind of Inner guide system is devised, guide shell low side is sealed by end socket type, aeration not Inner guide, interior stream slurry
Liquid flows out small to the aeration of rising from guide shell bottom end side.
Taper redistributor is devised, air pocket is crushed, the redistribution of the flow path of bubble, inner member is consolidated
It is fixed.
Riser is combined with distributor, and being transported to middle and upper part to fresh feed gas is efficiently reacted.
Brief description of the drawings
Fig. 1 is the schematic diagram of the efficient heterophase reactor of the present invention.
Fig. 2 is the longitudinal section of the distributor of reactor shown in Fig. 1.
Fig. 3 is the top view of the distributor of reactor shown in Fig. 2.
Fig. 4 is the cross-sectional view of the redistributor of reactor shown in Fig. 1.
Embodiment
After gas enters bed by the nozzle of distributor, a large amount of minute bubbles are formed, because the band of gas flow rate is acted
With the slurries in bed carry out violent mixing；A part of gas is reacted in the bottom of reactor with catalyst, after reaction
Gas or no the unstripped gas of reaction in uphill process, is not carried out again by being located at secondary air distribution grid in the middle of inner sleeve
Distribution, is carried out after the broken and reformation of fluid flow patterns, bubble diameter diminishes to air pocket, reaction contact area increase, is urged
Changing reaction becomes more acutely, further to be reacted the complete and fresh unstripped gas of unreacted, and in the presence of heat exchanger
Remove unnecessary reaction heat；Another part gas reaches the middle part of reactor by riser, and gas sprays from riser aperture
Tiny bubble so that the gas holdup of the middle part fresh feed gas of reaction becomes big, and gas transverse is stood with catalyst slurry
Body mass transfer and reaction, which improves the utilization rate of middle part catalyst and the utilization rate of space reactor.
When gas flow rate is larger, partial catalyst and solvent are taken to the top of reactor by gas, after heat exchanger
Reach top reducing expanding reach, same gas after reducing flow velocity continue reduce, separated in free surface area, partly with
After reactor jacket cylinder contact, in the presence of pressure difference and gravity, down flowed back at inner sleeve liquid collection opening, reach inner sleeve bottom
Portion, flows out, the gas haptoreaction with rising, continuation rises again, circulates from the return port of inner sleeve bottom side；This
The whole catalyst in reactor of sample and solvent are achieved that interior circulation, and concentration of slurry and viscosity can be just consistent substantially.
When gas flow rate continues to increase, partial catalyst and solvent are still obtained by the reducing inner sleeve on reactor top
Less than separation, the solid-liquid separator on reactor top will be entered, by solid-liquid separator, catalysts and solvents are back to reaction bed
Layer.
