Description
Technical field
The utility model relates to a kind of reactor matching component, relates in particular to a kind of gas distributor that is used for the synthetic fluidized-bed reactor of organic silicon monomer.
Background technology
At present, the production of industrial organic silicon monomer adopts the Rochow direct method synthetic usually, the material that participates in reaction is mainly methyl chloride gas, silica flour and copper powder etc., and the fluidized-bed reactor that is adopted structurally also has many unreasonable parts, so must make improvements.
The synthetic reactor of domestic organic silicon monomer all adopts general fluidized-bed reactor, and fluidized-bed reactor generally comprises bearing, cylinder, end socket, gas vent, conduction oil distributor, dactylethrae and air inlet distributor.Its key component is the gas distributor of bed body bottom, the quality of fluidization quality in its decision reactor.Reaction in the synthetic fluid bed of organic silicon monomer belongs to gas-solid fluidization, and fluidization quality is very big to the reaction influence, can have influence on reaction rate and yield.
At present, the fluidized bed layer main body mostly is the combination of cylinder or cylinder and circular cone, and its gas distributor that adopts is generally flat-plate pore-opening and adds pore formula gas distributor.The pore of this distributor and the perforate on the flat board are in a straight line, so its maximum shortcoming is the situation that can produce the blanking plug-hole can fluctuate owing to generations such as gas tolerance, pressure in process of production the time.Particularly for various reasons, when dying, a material falls in a large number in the bed, and the gas distributor lower space will all block, and causing can't ordinary production and be forced to parking maintenance, because the aperture of pipe is less, has increased the difficulty of maintenance.
The utility model content
The purpose of this utility model provides a kind of gas distributor that is used for the synthetic fluidized-bed reactor of organic silicon monomer, to overcome owing to fluctuation of service in producing or to stop the supple of gas or steam suddenly for various reasons, a large amount of solid materials fall from the hole, make the distributor bottom by a large amount of clogged up with material, ordinary production is forced to the defective of parking maintenance again.
The technical solution of the utility model is:
A kind of gas distributor that is used for the synthetic fluidized-bed reactor of organic silicon monomer that the utility model provides comprises several layers of gas distribution grid, and each layer gas distribution grid superposes mutually.
Each layer gas distribution grid is provided with the pore of diameter 2～15mm, and percent opening is 0.01～15%, and the pore quantity that is provided with on each layer gas distribution grid is by percent opening and aperture decision.The distribution of gas plate thickness is according to the weight decision of contact in the bed, and the pressure drop of gas distribution grid is 5%～150% of reactor bed pressure drop, and the thickness of slab of each layer gas distribution grid is at 2～15mm, and the distance between plates of each layer gas distribution grid is 2～15mm.
Preferably, gas distributor is provided with 1～5 layer of gas distribution grid.
Preferably, the stack of each layer gas distribution grid, pore is pressed the staggered floor setting on each layer gas distribution grid, i.e. and the gas distributor integral body of each layer gas distribution grid stack is not provided with through hole on it.
Preferably, gas distributor is provided with 3～5 layers of gas distribution grid.The lower part fabric swatch plays gas distribution effect in advance in principle, and the big hole count in aperture is less, and the intermediate section fabric swatch plays pressure stabilization function, and the little hole count in aperture is also less, and the top fabric swatch plays the effect of uniform gas, and the little hole count in aperture is more.Arranging between each distribution of gas hole can be by triangular formula or square arrangement or concentric circles arrangement.
Preferably, also be provided with the stainless steel Graphite pad between each layer gas distribution grid, this pad plays the effect of sealing.
The beneficial effects of the utility model are:
The gas distributor that is used for the synthetic fluidized-bed reactor of organic silicon monomer described in the utility model, characteristics are to adopt the multilayer staggered floor construction, by the staggered generation that prevents the blanking closure plate in each laminate hole, guaranteed that fluidized-bed reactor can remain on always when ordinary production that the gas-solid mixture has guaranteed the normal operation of production in certain fluidisation attitude in the bed.Also can satisfy different technological requirements on producing simultaneously according to the quantity of production requirement increase or minimizing plate.For the processing and manufacturing aspect, the difficulty of processing of board-like distributor adds the pore formula well below flat-plate pore-opening.
Description of drawings
Fig. 1 is the structural representation of the utility model gas distributor one embodiment.
The specific embodiment
Further specify architectural feature of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1, be used for the gas distributor of the synthetic fluidized-bed reactor of organic silicon monomer, comprise 3 layers of gas distribution grid 1,2 and 3, each layer gas distribution grid is provided with pore 11,21 and 31, each layer gas distribution grid superposes mutually, and pore 11,21 and 31 is crisscross arranged.
In a bed diameter of phi is 300mm, height of bed H is in the fluid bed made from lucite of 4000mm, and with the silicon powder particle of air as fluidized gas fluidisation production usefulness, the average grain diameter dp of the silicon powder particle of production usefulness is 0.155mm, the particle diameter dpmax of the largest particles is 0.510mm, just with 3 layers of distribution grid, ground floor perforate aperture is 2mm, and percent opening α is 1%, second layer perforate aperture is 4mm, percent opening α is that 0.5%, the three layer of perforate aperture is 4mm, and percent opening α is 2%.Behind the minimum fluidizing velocity umf of fluidized gas gas speed greater than the silicon powder particle of production usefulness, detect by an unaided eye, big and small particle all is in the fluidisation attitude, and the particle of whereabouts is blown afloat at random, does not have the charcoal particle of stop on distributor, does not promptly have the dead band to produce.
In a bed diameter of phi is 220mm, height of bed H is in the hot-die fluid bed of 6000mm, with CH3Cl as fluidized gas fluidized silicon powder particles, in reaction temperature is 300～310 ℃, reaction pressure is under the condition of 0.3MPa, synthetic reaction generates organic silicon monomer, the average grain diameter dp of silicon powder particle is 0.135mm, and the particle diameter dpmax of the largest particles is 0.450mm, and distribution grid adopts 2 layers, ground floor perforate aperture is 3mm, percent opening α is 2%, and second layer perforate aperture is 6mm, and percent opening α is 1%, second layer perforate aperture is 6mm, and percent opening α is 5%.When fluidized gas gas speed during greater than the minimum fluidizing velocity umf of charcoal particle, fluid bed can normally move, and through test in continuous 672 hours, reaction conversion ratio and the yield situation during with actual industrial production fluid bed ordinary production greatly was basic identical.Stop and dismantle the surface that distributor is observed in the back, without any sintering phenomenon, show that silicon powder particle does not have accumulation on the surface of multi-layer plate-type distributor, the even silicon powder particle of distribution of gas can not rest on the distribution grid, promptly can not produce the dead band, show that this multi-layer plate-type distributor can be used in the synthetic fluid bed of organic silicon monomer.
