Background technology
Fluidized-bed reactor is a kind of important chemical reactor that is easy to maximize and produces, and is specially adapted to strong exothermal reaction.In order in time to get rid of reaction liberated heat meter, a large amount of heat-obtaining tube banks generally all is set in fluid bed inside, heat removing tube is U-shaped pipe or thimble tube.The reactor of traditional structure adopts the tube-sheet type hanger structure usually, perhaps the square steel hanger structure.The reactor of tube-sheet type hanger structure connects safely in order to guarantee a large amount of U-shaped tube and tube plates, and the tube sheet material required thickness is larger, and the waste metal material increases platform load simultaneously, and manufacture difficulty increases.And the reactor of square steel hanger structure at the suspension bracket section, because sectional area diminishes, easily makes reacting gas raise speed and the aerodynamic field of upset inside reactor, and reaction efficiency is reduced.
In addition, in fluidized-bed reactor, during following material reaction, easily form turbulent or vortex phenomenon at fluidized state, cause reaction zone unstable, the temperature field is inhomogeneous, and reaction efficiency descends.And reaction generates the catalyst of easily carrying fine particle in the gas secretly, has increased the load of reactor rear portion three-stage cyclone separator.
Summary of the invention
The invention provides a kind of a kind of vertical fluidized rational in infrastructure, that steel consumption is little, heat-transfer effect is good and answer reactor.
For achieving the above object, the technical solution used in the present invention is:
A kind of vertical fluidized bed bioreactor, comprise cylindrical shell, be opened in material inlet and the catalyst inlet of described cylinder body bottom, be opened in the products export at described cylindrical shell top, be arranged on the material distributor of described inner barrel between described material inlet and catalyst inlet and the heat exchange structure that is arranged on described inner barrel, described heat exchange structure comprises the heat-obtaining tube bank, heat-conducting oil pipes, described inner barrel has: the reaction zone that is positioned at described cylinder body bottom, be positioned at the heat transfer zone on described cylindrical shell top, described heat-conducting oil pipes is arranged on described heat transfer zone, described heat-obtaining tube bank extends to described reaction zone from described heat transfer zone, described heat-conducting oil pipes is fixed in the described cylindrical shell, described heat-obtaining tube bank is connected on the described heat-conducting oil pipes, and the tube bank of described heat-obtaining is connected with described heat-conducting oil pipes.
Preferably, described inner barrel is provided with the block piece of lattice-shaped, and described block piece is arranged on the top of described reaction zone.
Preferably, described products export is provided with the water conservancy diversion separator, and described water conservancy diversion separator has a plurality of diversion outlets, and the internal face of described diversion outlet is wavy.
What preferably, the extending direction of described heat-conducting oil pipes and cylindrical shell axial line was perpendicular is fixed in the described cylindrical shell.
Because technique scheme is used, the present invention compared with prior art has following advantages:
The present invention replaces original tube sheet or square steel suspension bracket with heat-conducting oil pipes as suspension bracket, this tubular type hanger structure is less on the sectional area impact on reactor top, and the power of having avoided reactor shell because sectional area reduces the reacting gas speed-raising to be caused breaks ring, reduces reaction efficiency; Heat-conducting oil pipes is connected with the heat-obtaining tube bank in addition, on the one hand heat removing tube is done up supporting role, has also increased on the other hand heat transfer area, has strengthened the heat-transfer effect on reactor top.
