The gas is evenly distributed, the heat exchanging structure is convenient in installation and maintenance, and the utility model is applied in directly synthesizing monomer methyl chloresilane.
Description
Technical field
The utility model relates to a kind of chemical reactor, particularly relates to a kind of fluidized-bed reactor.
Background technology
At present, the fluidized-bed reactor that direct method synthesizing methyl-chloro-silane monomer is used, its syngas outlet is arranged on fluid bed upper cover top, and the heat exchanger tube of fluid bed inside needs maintenance or replacing after using certain hour, before each dismounting heat exchanger tube, all bigbore syngas outlet and other adapter mouth will be unloaded, it is very inconvenient to operate; Secondly, the gas distribution grid in the fluid bed is a sieve tray, and it is uneven easily to cause gas to distribute, and influences fluidization quality; Moreover, the direct method synthesizing methyl-chloro-silane is a strong exothermal reaction, for in time discharging the reaction liberated heat, U type pipe or thimble tube generally all are set as heat exchange structure in fluid bed, 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.And a large-scale fluidized bed reactor has dozens or even hundreds of heat exchanger tube, adopts this kind mode, and heat exchanger tube and outer tube joint are too many, and it is very inconvenient to install and overhaul.
The utility model content
The purpose of this utility model is to provide installation, maintenance convenient, and unstrpped gas is evenly distributed, the fluidized-bed reactor that fluidization quality is high.
The utility model fluidized-bed reactor comprises a body, the upper cover that is connected with bed body upper end, be connected and be provided with the low head of raw material gas inlet with bed body lower end, be looped around the semicanal on the external wall of bed, be arranged on the heat exchange structure in the body, be arranged on the short tube type gas distribution grid of bottom in the body, and be distributed in syngas outlet on the body, detect mouth, slag-drip opening, charge door, reach heat conductive oil inlet and outlet.Wherein, the bed body is made of top cylindrical shell and bottom cone; Heat exchange structure is connected and equally distributed droop suspension thimble tube bundle with the conduction oil distributor box by the conduction oil distributor box that is arranged on upper end in the cylindrical shell, and the resiliently mounted banded penstock dish of thimble tube Shu Jinhang group is formed.The banded penstock dish is a plurality of, is distributed in each section of thimble tube upper, middle and lower, is used for the flexible fastening of thimble tube bundle, it can not arbitrarily be swung, but allow every thimble tube slightly to vibrate within the specific limits, can effectively suppress solid material gathering on thimble tube, reduce coking.Simultaneously,, make each banded penstock dish have bigger hole rate, can not influence Flow of Goods and Materials in the body, thereby improve fluidization quality greatly because a plurality of banded penstock dishes are fixed some thimble tubes respectively.Conduction oil evenly flows in the every thimble tube chuck from the conduction oil distributor box, imports the conduction oil distributor box from the thimble tube centre bore after heat exchange, flows out fluid bed again; The percent opening of short tube type gas distribution grid, short tube major diameter when aperture pass through to calculate, make it reach optimum efficiency, unstrpped gas is gone into fluidized-bed reactor through the short tube rectification is laggard, can significantly reduce the turbulent flow of gas, distribution of gas is more even, simultaneously, the solid material under the situation of stopping the supple of gas or steam suddenly in the fluid bed can not fall into below the short tube type gas distribution grid, the startup of can ventilating once more easily; Syngas outlet is arranged on the side of conduction oil distributor box bottom cylindrical shell, makes things convenient for the maintenance or the replacing of thimble tube.Charge door and slag-drip opening are arranged on the cone lower end, charge door silica flour charge door during synthesizing methyl-chloro-silane.Heat conductive oil inlet and outlet comprise thimble tube heat conductive oil inlet and outlet and semicanal heat conductive oil inlet and outlet, and the former is separately positioned on cylindrical shell top and surveys face and upper cover napex, and the latter is separately positioned on the cylindrical shell side.Detect mouth and generally comprise a plurality of temperature-measuring ports and pressure tap, be arranged on cylindrical shell and the cone, be used for the detection and the control of temperature and pressure.
The course of work of the utility model fluidized-bed reactor is, unstripped gas enters from raw material gas inlet, go in the fluidized-bed reactor by the rectification of short tube type gas distribution grid is laggard, with the solid material reaction that enters from charge door, the product that generates is derived by syngas outlet, after reaction finished, residue was discharged by slag-drip opening in the fluidized-bed reactor.Temperature and pressure in the fluidized-bed reactor is detected and control by temperature-measuring port and pressure tap respectively.Thimble tube in semicanal on the external wall of bed and the bed body is removed the reaction liberated heat by the circulation of conduction oil.
The advantage of the utility model fluidized-bed reactor is to adopt the short tube type gas distribution grid, and unstrpped gas is evenly distributed, and has improved fluidization quality.Simultaneously, this heat exchange structure, thimble tube is minimum with outside tube connector, makes the integral hoisting of thimble tube bundle energy, gives installation and maintenance or brings great convenience, has also improved fluidization quality simultaneously greatly.Syngas outlet is arranged on the side of conduction oil distributor box lower bed, has both made things convenient for and being connected of outer tube, and does not influence the dismounting of thimble tube again.Be exclusively used in direct method synthesizing methyl-chloro-silane monomer.
