Technical field
The utility model belongs to chemical industry equipment fluidized-bed reactor technical field, more particularly relates to the improvement of the bipyramid flow-guiding type air inlet distributor of organic silicon monomer fluidized bed reactor.
Background technology
At present both at home and abroad the reactor that uses during synthesizing organosilicon monomer mostly is fluidized-bed reactor greatly.
The gas distributor of domestic existing fluidized-bed reactor roughly has two kinds, and the one, cone sieve plate type, another kind are that bubble-cap is plate.The structure of cone sieve plate type is the sieve aperture that has a series of even layouts at the cone sidewall, and opening diameter and hole count can be determined according to the gas flow and the flow velocity of technological requirement.The awl end, connect the catalyst ingress pipe, and catalyst adds fashionable, taken over by the awl end by inert gas or circulating air and spray into bed.Sidewall connects gas inlet.Plate then independently setting of bubble-cap added the catalyst charging gear.
The advantage of cone sieve plate type is: be convenient to catalyst and add, and can make the catalyst of newly adding lean on the expansion of cone to be distributed in the whole bed cross section, make catalyst and reaction mass full contact; Gas flows into by side-wall hole, and appropriate design by aperture, percent opening and the cone dilating effect that enlarges gradually of diameter from bottom to top can make gas uniform as far as possible; Strengthen the fluidization quality of fluid bed bottom, prevent and reduce a bottom caking and distribution grid stops up.But along with the increasing of process units ability, reactor diameter is multiplied, and air inlet has only one or two, and this will cause along the cone ambient pressure inconsistent, and the flow velocity of each sieve aperture differs.That is to large-scale reactor, it is further uniform preferably that cone sieve plate distributor is difficult to make gas to be realized.The distribution of gas inequality can cause an interior fluidization conditions to differ, and influences the quality of production and reaction yield.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned shortcoming and defect, and a kind of bipyramid flow-guiding type air inlet distributor of organic silicon monomer fluidized bed reactor is provided.It can guarantee inner cone side pressure homogeneous by the row of one on outer cone and cone pod apertures, avoided former fluid bed cone distributor to need two imports, and the inlet pressure height, the drawback that other site pressure decreases can be guaranteed along reactor cross section gas flow rate homogeneous.Thereby further reduce production costs, improve the quality of products and reaction yield.
In order to achieve the above object, the utility model comprises following cylinder and the low head thereof, the air inlet that is fixed on down the cylinder side that are fixed on below the reactor lower cone, is fixed on down the cone sieve plate in the cylinder and is fixed in the middle of the low head and the catalyst ingress pipe of cone sieve plate lower end.Have the sieve aperture of even layout on the cone sieve plate.Gas inlet has only one.Cone sieve plate outside is gone back suit and another outer cone-plate, and outer cone-plate also is conical, has row's pod apertures on the outer cone-plate, and a side of pod apertures has the deflector of inclination.
Pod apertures on the outer cone-plate can be rectangular opening or diamond hole, and the area of pod apertures has nothing in common with each other.Pod apertures can be uniform or non-uniform.Above-mentioned shape, area, uniform or non-uniform all should be according to the kind that enters gas, flow, pressure optimal design so that even gas distribution flow into.That is to say that pod apertures should be calculated as foundation with flow field simulation, arrange according to certain way.
The vial support that fluidized-bed reactor generally comprises bearing, be fixed on cylinder on the bearing, be fixed on top cylinder and end socket thereof on the cylinder, be installed in gas vent on the end socket, be fixed on the inner conduction oil distributor in cylinder upper end, be connected dactylethrae on the conduction oil distributor, vial is connected as a single entity, be fixed on lower cone below the cylinder, be fixed on the air deflector internals in the lower cone and be fixed on air inlet distributor below the lower cone.
This bipyramid flow-guiding type air inlet distributor is that the air inlet at organic silicon monomer fluidized bed reactor requires to develop.The air inlet that enters reactor has only one, is single air inlet.Cone-plate outside the air inlet place is provided with, outer cone-plate also are conical, have row's pod apertures on the outer cone-plate, and a side of all pod apertures has the deflector of inclination.After making gas enter outer cone inside, along inner cone surface pressing unanimity.Inner cone is a sieve plate shape, and because of inner cone side surface pressure unanimity, and perforate is uniform, and air-flow is evenly entered in the awl along inner surface, makes whole reactor cross section gas flow rate uniform by the dilating effect of cone.Cone base connects the catalyst ingress pipe, and the catalyst of newly adding can be blown into from end mouth by air-flow, by the inner cone peripheral intake catalyst is further disperseed, and enters bed by the inner cone water conservancy diversion.
The deflector that tilts is formed by the material turnover at pod apertures place, economical with materials, and also processing technology is good.
Task of the present utility model comes to this and finishes.
The utility model can guarantee inner cone side pressure homogeneous by outer cone-plate and pod apertures, avoided former fluid bed cone distributor to need two imports, and the inlet pressure height, the drawback that other site pressure decreases can be guaranteed along reactor cross section gas flow rate homogeneous.Thereby further reduce production costs, improve the quality of products and reaction yield.It can be widely used in the production of organic silicon monomer.
