The purpose of this utility model is achieved in that it is made up of bed body, riser, riser, gas distributor, charging aperture, filter, heat exchanger tube, air inlet, exhaust outlet and discharge port.It is characterized in that a body constitutes by two sections, bed body epimere is the equal diameter cylinder, and hypomere is a pyramidal structure, and both connect by spherical changeover portion.The riser of a upper end diameter greater than lower end diameter is equipped with in the bottom in the bed body, the equidistant snake type heat exchanger tube that is wound with in the riser outside.Gas distributor is positioned at the riser bottom, and there is charging aperture on bed right side, body bottom, and there is discharge port bed pyramidal structure side, body bottom, air inlet is arranged at the bottom, and air inlet communicates with gas distributor and riser, and the distribution of gas hole is arranged at riser top, filter is equipped with on bed body top, and there is exhaust outlet on bed body top.
Slurries flow in the bed body by charging aperture, gas then enters in the riser by gas distributor and riser through air inlet, and the slurries that carry in the riser move upward together, gas and slurries in the riser carry out mass transfer, conduct heat and reaction, the product gas that reaction generates, unreacted unstripped gas is with after the slurries carried secretly separate through filter, product gas and unreacted unstripped gas are discharged by the exhaust outlet on bed body top, and the slurries stream that falls that up slurries enter between a body and the riser through the riser upper end in riser is distinguished, and be back in the riser in the bottom that falls stream district, unnecessary slurries are discharged by discharge port.Simultaneously, cooling fluid is entered by heat exchanger tube inlet, and discharges from the heat exchanger tube outlet after the slurries heat exchange.
The utility model compared with prior art has the following advantages:
1. bed body of the present utility model constitutes by two sections, epimere is the equal diameter cylinder, and link to each other with the hypomere pyramidal structure by spherical changeover portion, this structural design can guarantee that the slurries that fall the stream district in the reactor are back in the riser smoothly, avoids dead bed occurring at reactor bottom;
2. in the bed body of the present utility model the reducing riser is housed, can effectively improve the CONCENTRATION DISTRIBUTION of slurries in the riser, gas-liquid is mixed admittedly, simultaneously, unstripped gas distributes and the catalyst concn basically identical in reactor vertically, make the maximum reactivity of catalyst performance, compare, can increase substantially the disposal ability of reactor with other unidimensional reactors;
3. the equidistant snake type heat exchanger tube that is wound with in the riser outside when cooling fluid is flowed through heat exchanger tube, is in time removed the heat in the reactor, makes reaction temperature keep stable, avoids occurring the bed focus, prolongs life of catalyst;
4. the utility model adopts the side-flow type gas distributor, blast cap is tapered, slurries can not pile dead bed at the blast cap top, blast cap becomes equilateral triangle to arrange on gas distributor, between per three blast caps just like forming a fine taper bed, on gas distributor, just form a plurality of fine taper beds like this, the even substep that helps solid catalyst, in addition, gas is close to gas distributor plate surface current along latasuture and is gone out, turn back then and upwards enter bed, can make gas on gas distributor, obtain evenly to distribute, prevent that the plate face from forming dead bed or sintering phenomenon takes place;
5. the riser that communicates with gas distributor is housed in the reactor, radially be evenly distributed with six distribution of gas holes in axial three positions of riser, and increase with axial location, the distribution of gas bore dia increases, so just can in time replenish the used up material synthesis gas of riser internal reaction, unstripped gas be distributed vertically reach unanimity, in addition, the awl cap is adopted on the riser top, avoids slurries to form the dead band at its top;
6. reactor top is furnished with filter, after reacting the product gas that produces and the slurries that unreacted unstripped gas and its are carried secretly being separated through filter, slurries turn back in the reactor, product gas and unreacted unstripped gas are discharged by exhaust outlet, can effectively reduce the slurries loss, simultaneously, can reduce product gas subsequent treatment cost, make production process simpler, easy to operate.
