Background technology
Fluidized-bed reactor is one of key equipment of organosilicon production, and what organosilicon synthesis reactor mainly adopted at present is a kind of reactor between fluid bed and fixed bed form, and in industry, custom is called fluidized-bed reactor.In fluidized-bed reactor, gaseous chlorine methane and solid-state silica flour reaction generate organic silicon monomer.Methyl chloride gas enters reactor by reactor bottom, reacts with the silica flour being filled in reactor.Chloromethanes carries out with reacting under the high temperature more than 350 DEG C of silica flour, and the heat that reaction generates is very large, needs in time reaction heat to be removed in reactor, reacts smoothly, carries out safely to ensure.The course of reaction that generates organic silicon monomer is gas-solid phase reaction, and the heat transfer efficiency in reactor is lower, how the heat in reactor is removed rapidly significant.
At present, organosilicon fluidized bed reactor conventionally adopts and in reactor, arranges that the dactylethrae of some removes the heat in reactor.Contact with gas with silica flour because dactylethrae only has outer layer sleeve, the heat exchange area of unit bed volume is lower; Dactylethrae is internal and external casing structure in addition, and the external diameter of pipe is relatively large, and in bed, tube pitch is also larger, has hot-spot phenomenon in bed.
Summary of the invention
The purpose of this utility model is: a kind of U-shaped pipe organosilicon fluidized bed reactor is provided, it is rational in infrastructure, heat transfer efficiency is high, methyl chloride gas and silica flour and U-shaped heat exchanger tube contact-making surface are large, uniformity of temperature profile in bed, be conducive to improve reaction conversion ratio, improve the efficiency of organosilicon fluidized bed reactor.
Technical solution of the present utility model is: this U-shaped pipe organosilicon fluidized bed reactor comprises reaction zone cylindrical shell, top expands bobbin carriage and bottom bobbin carriage, top enlarged tube case and bottom bobbin carriage are installed respectively in top and bottom at reaction zone cylindrical shell, on top expansion bobbin carriage, be set as the outlet of product gas and silica flour charge door, on the bobbin carriage of bottom, establish solid material floss hole, it is characterized in that: some U-shaped heat exchanger tubes are installed in reaction zone cylindrical shell, top expands on bobbin carriage establishes cooling medium inlet house steward and cooling medium outlet header, in U-shaped heat exchanger tube, walk cooling medium, between U-shaped heat exchanger tube, load silica flour, on reaction zone cylindrical shell, be provided with some chloromethanes playpipes, the tangent line shape of chloromethanes playpipe and cylindrical shell mounting points has a certain degree, methyl chloride gas forms and rises and rotation status in reactor, and chloromethanes playpipe is all connected on a chloromethanes house steward around cylindrical shell in the extension of cylindrical shell outside, installing gas distribution grid in cylindrical shell below chloromethanes playpipe, gas distribution grid is provided with some distribution of gas hole, is provided with chloromethanes secondary inlet on the bobbin carriage of bottom.
Wherein, top expansion bobbin carriage diameter is obviously greater than reaction zone barrel diameter.
When use, silica flour adds by silica flour charge door is disposable, raw material methyl chloride gas enters each chloromethanes playpipe through chloromethanes house steward, in reactor, react with silica flour, the organosilicon gas that reaction generates goes finished product to refine workshop section by the outlet of finished product gas, and the heat that reaction generates is taken away by the cooling medium in U-shaped heat exchanger tube; In the time of silica flour negligible amounts in reactor, methyl chloride gas is entered gas distribution grid and entered reaction zone by distribution of gas hole by the chloromethanes secondary inlet of bottom bobbin carriage reacts with silica flour.
The utlity model has following advantage: 1, gas is evenly distributed in silica flour inside, avoid channel, short circuit phenomenon; 2, the heat exchange area of unit bed volume is large; 3, U-shaped heat exchanger tube diameter is less, and U-shaped heat exchange tube spacing is little, overcomes bed hot-spot phenomenon; 4, bed radial temperature profile is even; 5, reaction conversion ratio is high.
