It is suitable for the reaction of liquid-solid suspension system with high content of solid.
Description
Technical field
The present invention relates to reactor, relate in particular to a kind of oscillatory flow tubular reactor of balking ring baffle.
Background technology
Oscillatory Flow Reactor is a kind of novel chemical industry equipment that the wide range of industrial applications prospect is arranged, and is applicable to liquid phase or based on the multiphase flow course of reaction of liquid phase.Oscillatory Flow Reactor has good transmission characteristic, also has time of staying distribution comparatively uniformly under the very low condition of mean flow rate, can provide under many circumstances than common tubular reactor and the better reactivity worth of stirred-tank reactor.There has been at present the baffle arrangement of the Flapper type oscillatory flow tubular reactor of research and application report mostly to be plane orifice plate type baffle plate (single hole or porous), when being applied to contain the reacting fluid system of more solids, easily (when reactor is vertically installed) or forward and backward side (when reactor level is installed) accumulation above baffle plate of solids, thus cause reactor long-time continuous stable not move.This drawbacks limit the application of such reactor for solid-liquid catalysis or uncatalyzed reaction system.
Summary of the invention
The purpose of this invention is to provide a kind of oscillatory flow tubular reactor of balking ring baffle, be applicable to the catalysis or the uncatalyzed reaction process of the liquid-solid suspension system that solid content is higher, can the long-time continuous stable operation.
It is made up of the vibration generating mechanism, inducer, conversion zone, the outlet section that are connected successively, on inducer, be provided with charging aperture, on outlet section, be provided with discharging opening, conversion zone is made of the circular reaction tube of positioned vertical, be provided with the conical ring baffle plate of vertically arranging in order in the pipe, the space is separated into the multi-cavity cell structure in will managing.
The conversion zone of conical ring baffle plate Oscillatory Flow Reactor can or be composed in series by many reaction tubes parallel connections, so that sufficiently long mean residence time to be provided.
The conical ring baffle plate of reaction tube inside interlinks by the baffle spacer of regular length, between the backstay with being threaded.
The cone-apex angle of conical ring baffle plate is between 45 °～170 °, and the ratio of the internal diameter of conical ring perforate and the external diameter of conical ring can be made with the sheet material of 1～10 millimeter thickness between 0.2～0.8.
The mounting means of conical ring in reaction tube should be that the conical surface is outstanding downwards, and promptly the upper surface of baffle plate is a concave surface, and lower surface is a convex surface.
The outer surface of reaction tube can also be provided with heat exchange jacket, provides heating, cooling or heat-retaining condition by the heat transferring medium that adds in the cover for reaction tube.
Advantage of the present invention is:
Under the continued operation condition, have than the more uniform time of staying distribution of tank reactor;
Under the very low condition of mean flow rate, have than the more uniform time of staying distribution of common tubular reactor;
Under the very low condition of mean flow rate, still has the good heat transfer performance between fluid in the reactor and the wall;
Regulate oscillation intensity, solids were suspended in the liquid of inside reactor equably, also can allow solids form the stable distribution that number density from top to bottom strengthens gradually;
The fluid of inside reactor and the surface between the suspended particles are brought in constant renewal in, and transmittance process is strengthened;
Conical ring baffle plate upper surface is an inclined downward in the reactor, can prevent the accumulation of solid particle above baffle plate effectively, thereby reactor still can steady in a long-term be operated under fluid solid content condition with higher.

The specific embodiment
Oscillatory flow tubular reactor of balking ring baffle is made up of the vibration generating mechanism 1 that is connected successively, inducer 2, reaction tube 4, outlet section 7, on inducer 2, be provided with charging aperture 10, on outlet section 7, be provided with discharging opening 8, reaction tube 4 is made of the circular reaction tube of positioned vertical, be provided with the conical ring baffle plate of vertically arranging in order 11 in the pipe, the space is separated into the multi-cavity cell structure in will managing.
Conversion zone can be made up of many reaction tube serial or parallel connections, so that the enough reaction compartment and time of staying to be provided.Connect with bridge piece between the many reaction tubes.
The conical ring baffle plate 11 usefulness baffle spacers 12 of reaction tube inside connect the location, keep the locus of each baffle plate and the distance between the baffle plate.
The outer setting of reaction tube 4 has heat exchange jacket 3, and the cone-apex angle of conical ring baffle plate is 120 °, and the conical ring internal diameter is 0.5 with the ratio of external diameter.The conical surface of conical ring baffle plate is outstanding downwards.
Reactor of the present invention has the tubular type shell of positioned vertical, and shell is outer can to have heat exchange jacket, provides reaction tube inner required temperature conditions.Reaction tube inside is provided with and vertically goes up the baffle plate of arranging in order.Baffle arrangement is the conical ring face shape of middle part perforate, and the conical ring internal diameter can be selected in 0.2～0.8 scope with the ratio of external diameter, and conical ring is outstanding towards the below.Available backstay connects between baffle plate.The feed end of reactor is provided with the vibration generating mechanism, produces a reciprocating vibration motion that is superimposed upon on the mean flow rate in the fluid of reaction tube inside.The structure of conical ring baffle plate Oscillatory Flow Reactor referring to accompanying drawing 1 to accompanying drawing 3.
Reactor when work, the reacting fluid reaction tube inside of flowing through, the oscillating movement that the vibration generating mechanism produces in fluid interacts with baffle plate, generates the constantly vortex of variation of position and size in chamber.Swirl flow provides good radially mixing in chamber, make the more uniform distribution of time of staying trend of reacting fluid, even under the very low situation of mean flow rate, also can improve time of staying distribution effectively.The strong turbulence that vortex movement causes can also enhanced reactor inside transmittance process, and keep solids to be suspended in the reacting fluid equably.The above feature of oscillating flow field can provide favourable reaction environment for the solid-liquid suspension system, thereby obtains good reactor performance.The conical surface of conical ring baffle plate is outstanding downwards in the reactor installs, and the baffle plate upper surface is an inclined downward, can prevent the accumulation of solid particle above baffle plate effectively, thereby reactor still can steady in a long-term be operated under fluid solid content condition with higher.
