Description
Technical field
The utility model relates to a kind of fluidized-bed reactor.
Background technology
Methylchlorosilane is a field of organic silicon material commonly used, the direct method synthesizing methyl-chloro-silane is a strong exothermal reaction, for in time getting rid of liberated heat, U type pipe or thimble tube generally all are set as heat exchange structure in fluid bed, and the every pipe that present U type pipe that uses or thimble tube have is connected with outer tube separately, what have organizes with several Guan Weiyi, is connected with outer tube then.But, because reaction is lumpd easily, cause fluidized state to worsen, product quality descends, and reaction selectivity reduces.During the fluid unit maintenance, need other equipment such as top cylindrical shell and upper cover are unloaded, it is very inconvenient to operate.
For very big large-scale fluidized bed of exothermic heat of reaction amount, dozens or even hundreds of heat exchanger tube arranged, the adding of heating surface bank, significantly reduced the net sectional area of bed body, for equal cylinder fluid beds straight, container causes empty tower gas velocity too high, thereby makes the granularity smaller particles be blown a body easily, thereby influences course of reaction.
Distribution grid is an important component part of industrial fluidized bed equipment.The fluidization quality of whole fluid bed and the operating characteristics of reactor all had important effect.The distributing plate structure that existing fluid bed uses is comparatively simple, stephanoporate steel plate just, and each aperture also is covered with one section angle steel, makes air-flow along the ejection of distribution grid level and prevent that particle from falling under the plate.
In addition, the bottom section of general fluid bed adopts conical bed, improves all abundant fluidisation of material that fluidizing velocity makes different-grain diameter.
Summary of the invention
The purpose of this utility model is to provide a kind of fluidized-bed reactor.This fluidized-bed reactor is particularly suitable for synthesizing methyl-chloro-silane.
The purpose of this utility model reaches by following scheme:
Fluidized-bed reactor of the present utility model, comprise that conduction oil oil-feed distributor box and conduction oil go out fuel tank, conduction oil import and export, expanding reach cylindrical shell, straight cylinder body, unstrpped gas import and syngas outlet, wherein conduction oil oil-feed distributor box and conduction oil go out fuel tank and are connected with the thimble tube bundle and place expanding reach cylindrical shell and straight cylinder body, gas distribution grid is installed in thimble tube bundle lower end, wherein conduction oil oil-feed distributor box is connected with pipe upper end in the thimble tube bundle, and conduction oil goes out fuel tank and is connected with thimble tube bundle outer tube upper end; The unstripped gas side inlet is equipped with air flow guiding device, and the unstripped gas bottom inlet is equipped with gas distribution grid.
Wherein syngas outlet is arranged on outer ring, expanding reach cylindrical shell top.Syngas outlet is 2-10.
Expanding reach cylindrical shell crown center is provided with conduction oil oil-feed distributor box and conduction oil goes out fuel tank.
Gas distribution grid and air flow guiding device are installed in thimble tube bundle below.Air flow guiding device is installed in the gas distribution grid top.
The course of work of the utility model fluidized-bed reactor is, under certain temperature and pressure, partial raw gas enters in the fluid bed by air flow guiding device from unstripped gas sidepiece charging aperture, partial raw gas from unstripped gas bottom feed mouth in gas distribution grid enters fluid bed, with the solid particle reaction that enters from charge door, the product that generates is derived by syngas outlet, and the residue that reaction finishes in the post-reactor is discharged by slag-drip opening.
The utility model fluidized-bed reactor following advantages are arranged:
1) mode that adopts gas distribution grid and air flow guiding device to combine, the unstripped gas circle of contact and bottom inflow from the side enters, strengthened the inner lateral flow of bed, make that the interior gas-solid of bed is horizontal mutually and axial flow is more even, and forming whirlpool in fluid bed rises, prevent the deposition of solid particle, strengthened the heat and mass in the course of reaction, improved reaction yield.
2) adopt this heat exchange structure, thimble tube is connected with the conduction oil distributor box, and is simple in structure, is convenient to maintenance is installed, and increased an interior heat transfer sheet area, improved the fluidized state of whole bed, makes the easy control of temperature of gas phase section.
3) the expanding reach cylindrical shell is adopted on fluid bed top, makes the gas prompt drop low, and material is easy to deposit, and is difficult for being taken out of by gas, has reduced the load of subsequent separation system, improves the fluid bed conversion per pass, and energy efficient.
