Description
Technical field
Utility model is about the improvement to volatility different component rectifying column device in the separating liquid mixture, relates in particular to a kind of extra-high-speed viscosity (viscosity 〉=100,000 centipoises) blending ingredients material rectifying separator.
Background technology
Rectifying column is the device that separates the volatility different component from liquefied mixture commonly used in the chemical industry, basic structure is by the rectifying still and the rectifying column joint of serial connection are formed up and down, desirable rectifying separation requirement material to be separated can have good flowability in rectifying still, to reach even, efficient heat transfer.But some material is because viscosity is big, freezing point height, mobile low, mass transfer and heat-transfer effect are poor, mix hot bad, not only rectification effect is poor, and very easily cause equipment and line clogging, and rectifier unit is difficult to operate as normal, and the normal cycle of operation of equipment is short, cleaning is frequent, maintenance of equipment work amount is big, and operating cost improves, and has also reduced the production capacity of equipment.Sometimes stop up for preventing, can only take to reduce light component recovery rate mode, light component content in the heavy ends at the bottom of the raising tower, promptly " sacrifice " part light component is removed heavy ends viscosity with reduction, but for the higher light component of economic worth, the loss of this kind way is bigger, less economical.Therefore the rectifying of high viscosity, high-solidification point heavy component system separation is the big difficult point during rectifying separates always.
Chinese patent 02262729.4 discloses the rectifying device that a kind of title can be used for higher boiling, high-solidification point, high viscosity system, be characterized in being provided with in the jacket type rectifying column kettle barrel heat(ing) coil of stratiform coiling, and the pusher stirring blade that extends nearly bottom down, stirring blade is provided with guide shell outward.Though this structure has strengthened the heat transfer in the rectifying column still and treated the good stirring action of separation mixture, the actual rectifying separation that still only is applicable to the medium system of viscosity is for there being viscosity 〉=10 in the system to be separated
2Pa.s (100,000 centipoise), the extra-high-speed viscosity heavy component system of freezing point 〉=80 ℃ still can cause material to stop up, and be inapplicable.The one, for extra-high-speed viscosity heavy component system like this, only depend on the pusher stirring blade in bottom, still be difficult to really reach and make the high viscosity system form that volume is circulating to seethe, because " the volume circulation is seethed " effect is not obvious, material is mixed the irregular material that still can produce of heat and is deposited, and then the deterioration heat transfer causes " coking " to adhere to; The 2nd, along with the continuous extraction of rectifying tower top light fraction, the heavy component content ratio increases in the tower still, will cause system viscous force to be separated further to increase, and heat transfer, mass transfer situation worsen, and material seethes not obvious adhesion of effect; The 3rd, adhesion is in case generation is accumulating formation " fouling " on the stratiform heat(ing) coil and on the tower still wall, and the reduction of heating effective area can increase the weight of the adhesion of heavy component system more; The 4th, owing to be provided with the stratiform coil pipe in the tower still, generation adhesion back cleaning is very difficult, so this structure rectifying still is not suitable for the rectifying of extra-high-speed viscosity system.
Chinese patent 03253612.7 disclosed volatile oil distillation equipment, by at the distillation still center and proximal wall the rotating jet device is set, the jet that spray to form system by steam stirs.Jet stirs " the volume circulation is seethed " that more can not cause extra-high-speed viscosity system, therefore anti-coking is stopped up and do not have effect substantially, and in distillation process, do not allow system to contact with water and air for some, and for example the rectifying of carbonyls separates, and it is unallowed spraying into steam.Therefore the rectifying that also still is not suitable for extra-high-speed viscosity and avoids water, air system of this equipment separates.
Therefore, to so far, for viscosity 〉=10
2Pa.s, separate as the heavy component rectifying that need avoid water, air again freezing point 〉=80 ℃, does not have desirable rectifying column device.
The utility model content
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of can the adaptation especially to contain viscosity 〉=10
2Pa.s, the rectifying column device that the heavy component system rectifying of freezing point 〉=80 ℃ separates.
The utility model purpose realizes, the main improvement is that rectifying column still at rectifier unit axially is provided with long ribbon and bottom and the combination that the anchor formula stirs is set seethes agitating device, thereby overcome prior art and can not realize goal of the invention the undermixing of seething of extra-high-speed viscosity system.Specifically, utility model rectifying column device comprises the rectifying column joint and the rectifying still of serial connection up and down, it is characterized in that the long ribbon that axially extends nearly bottom is arranged in the said rectifying still, and anchor formula stirring arm is arranged at the ribbon bottom.
Utility model can realize seething the formula stirring to material in the still, thereby improve the heat transfer efficiency of high viscosity system greatly by axial long ribbon is set in the rectifying column still, has avoided gluing still because of system can not get fully stirring producing.For further improving extra-high-speed viscosity system " blending " formula is seethed, strengthen heat transfer effect, a kind of better is that said long ribbon adopts two ribbon structures, and adopt big radial dimension, said ribbon radial dimension is preferably the 2/5-4/5 of rectifying column still internal diameter, length is high 50-75% in the tower still, and big radial dimension and big length more help forming good " seething " blending and stirs.
The ribbon bottom can prevent effectively that not only high sticking material from sinking to the bottom sticking still, and cooperate with ribbon near the anchor formula stirring arm of still bottom surface, improve especially " seething " blending of material is stirred.A kind of anchor formula diameter that is more preferably can prevent that greatly to approaching radially peripheral wall surfaces of still, can play well to scrape the wall effect rectifying system from adhering to the still wall.
The utility model rectifying still is connected with top rectifying column joint, with similar usually, has no special requirements.
Utility model rectifying column device, owing to adopt the anchor formula stirring arm that axial long ribbon is set and extends the bottom in rectifying still, ribbon is forced material axially to stir, anchor formula slurry radially stirs, axially with radially the stirring that mixes, make material produce irregular convection current, shear, blending, diffusion, thereby " seething " blending omnidirectional three-dimensional that has improved high-viscosity material stirs, eliminated stirring, the mixed flow dead band, strengthened the abundant flowability of material in still, improved the heat transfer of rectifying material in still, thereby effectively overcome high viscosity, high solidifying point material is because of the bad deficiency that causes the adherence accumulation that flows in still, and material is to seethe in still, without any pipeline, be used for the rectifying of aforementioned extra-high-speed viscosity material, can not occur sticking still substantially and stop up.Adopt the utility model rectifier unit, continuous operating time can extend to 300-360 days by original pump forced circulation, reboiler 10-15 days service time to the thermal rectification device, realizes substantially need not shutting down cleaning the whole year; And because system " seethes " and flow, and thermally equivalent, also improved the amount of steaming of light component in the material in the tower still, made rectifying still discharge in the heavy ends light component content and reduce to below 3%, improved the economy of rectifying greatly by original 10-15%.And,, contingency also is easy to clear up and clean even taking place to stop up because rectifying still is " cavity ".The utility model device is specially adapted to 〉=and 10
2Pa.s extra-high-speed viscosity, freezing point 〉=80 ℃, the rectifying of avoiding the heavy component material of water, air again separates, and the rectifying that can also be used for other viscosity higher systems certainly separates.
