Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
As shown in drawings, this reactor adopts three layers of radially cold shock formula structure of fixed bed, traditional fixed bed reactor catalyst bed is divided into three layers of upper, middle and lowers, every layer of catalyzer upper and lower all has the cover plate for sealing structure, and the gas that the beds center and the outside have on the root canal wall formula in the shape of a spiral be uniform-distribution with the wide-angle perforate vertically respectively distribute outward tube 5 and gas inside distributor 6, distributing between tube 5 and the gas inside distributor 6 outside gas is catalyst particle bed 4.Under certain pressure, fresh synthesis gas after the purification mixes from feed-pipe with circulation gas) enter three sections radially cold shock formula reactors making by stainless material, by on gas inside distributor 6 walls at first section beds center in the shape of a spiral the equally distributed wide-angle of formula duct radially enter beds 4, on small-particle iron-based or cobalt-base catalyst, carry out the F-T building-up reactions, unreacting gas and reaction product are passed the gas tube that distributes outward) leave beds 4, by with reactor shell 2 in the boiling water heat exchange F-T building-up reactions liberated heat is shifted out reactor.Gas after the heat exchange is along the gas inside distributor 6 that axially enters second section beds center, by on the barrel in the shape of a spiral the equally distributed wide-angle of formula duct radially enter beds 4, on small-particle iron-based or cobalt-base catalyst, carry out the F-T building-up reactions once more, the gas that a small amount of unreacting gas and reaction product the are passed second section beds tube 5 that distributes outward leaves beds 4, enter the 3rd section beds vertically after the boiling water heat exchange once more with in the reactor shell 2, continue to repeat the reaction and the heat transfer process of second section catalyst bed interlayer.Last a small amount of unreacting gas and reaction product are by discharge nozzle 7 outflow reactors.
Because heat exchange is carried out in the segmentation of radially cold shock formula of multistage reactor, and the medium radial flow path is short, so reaction bed temperature is evenly distributed, no focus exists, the local temperature runaway of the beds of having avoided the strong heat release of F-T building-up reactions to cause.Simultaneously, the beds pressure drop is little, vapor-phase reactant is evenly distributed at beds, the F-T building-up reactions can be selected the catalyst particle that activity is high, specific surface area is big, because the influence of catalyst particle internal diffusion is little, the surfactivity center is many, so improved the utilization ratio of F-T synthetic catalyst greatly.At last,,, reduce production costs, reach the effect of Increasing Production and Energy Saving so can improve catalyst utilization by increasing the unstripped gas air speed because radially cold shock formula reactor heat-transfer effect is good.
