Description
Technical field
What the present utility model related to is a kind of gas distributor, relates in particular to a kind of distribution device in gas-fluid that is used in the silane fluidized-bed.
Background technology
Gas distributor or distribution device in gas-fluid are one of core vitals of fluidization equipment.Its Main Function is that the fluid that enters the fluidized-bed center is evenly distributed along the bed section, does not cause bed dead bed district to occur.
Whether the distribution device in gas-fluid structure is suitable, is one of key of fluidization operation success or failure.Successful distributor designs is mainly reflected in: one, and the stable operation that can keep for a long time fluidized-bed unlikelyly causes pressure drop obviously to change because of particle deposition; Its two, fluid is evenly distributed along the bed section, in the sparger near zone, gas-solid abundant contact, reaction; Its three, eyelet or slit in the sparger are not prematured by solids; Its four, flow reduces through the drag losses of sparger as far as possible, reduce energy consumption; Its five, simple in structure, make and easy for installation, in use be convenient to change.
The sparger that fluidized-bed uses in the prior art is not suitable for the silane fluidized-bed, and have some defectives in actual production: one: the sparger cap structure of prior art is inadequate aspect fluidizing stability, the generation of dead hole, dead band phenomenon is often arranged, affect the raising of reaction efficiency; Its two: the fully generation of deadband eliminating of sparger blast cap arrangement mode of the prior art, thus affected the anti-deposition capability of grid distributor; Its three, sparger of the prior art abrasion problem is more serious, affect fluidized-bed running steady in a long-term, can make grid distributor pressure drop reduction after the sparger abrasion, affects the even distribution of fluid, makes the fluidization quality variation, technological process can not normally be carried out.
The utility model content
The purpose of this utility model is can steady in a long-term to move in order to provide a kind of, and without dead hole, leakage material phenomenon, abrasion is few, is difficult for coking, and can improves the transformation efficiency of fluidized-bed reactor and the silane fluidized-bed distribution device in gas-fluid of quality.
Comprise for solving the problems of the technologies described above the utility model silane fluidized-bed distribution device in gas-fluid: gas distribution grid which is provided with air inlet port; Blast cap is arranged on the described air inlet port; The material collection pipe is arranged on the described gas distribution grid.Blast cap is preferably the semi-canal type blast cap, and the type of attachment of semi-canal type blast cap and gas distribution grid is welding.Two ports of semi-canal type blast cap are made as the jet hole of giving vent to anger.
Described air inlet port is equilateral triangle or square or circular concentric and evenly is arranged on the described grid distributor, and its percentage of open area is 1%～5%.It is staggered or trilateral is staggered or rhombus is staggered or circular concentric is staggered that described semi-canal type blast cap is square.
Described gas distribution grid is pyramidal structure, and semi-cone angle is 30 ~ 60 degree.
Preferably, described gas distribution grid semi-cone angle is 45 ~ 60 degree.
Described material collection pipe is arranged on the gas distribution grid bottom, mainly is the product particle silicon of collecting in the silane fluidized-bed.The type of attachment of described material collection pipe and gas distribution grid is for welding or being threaded.
