Technical field
The utility model belongs to a kind of industrial waste retrieving arrangement, is specifically related to a kind of device that reclaims triethyl aluminum from triethyl aluminum production raffinate.
Background technology
Triethyl aluminum, molecular formula: (C
2H
5)
3Al (aluminum triethyl) is mainly used in the preparation tertiary alcohol, secondary alcohol and polyolefin catalyst, also can do other organic compound raw material, aluminize etc.The synthesis technique of triethyl aluminum comprises following two big steps: the first step is a hydrogenation, is the phase reaction of hydrogen, seed triethyl aluminum, aluminium powder, generates ADEH; Second step was ethylation reaction, was the addition reaction of hydrogenation resultant (ADEH) and ethene, generated triethyl aluminum.The raw material aluminium powder is the important source material that triethyl aluminum is produced, and aluminium powder contacts with air in processing, transportation and storage process, can small amounts be aluminum oxide, enters as solid impurity in the triethyl aluminum product of production; In hydrogenation, often add titanium valve and make catalyzer, finally also enter in the triethyl aluminum product of production as solid impurity; The oxygen, the moisture that contain minute quantity in the raw material ethene that uses in the production, the hydrogen, the nitrogen that is used as system's pressurize, protection also contains oxygen, the moisture of minute quantity, the reaction of triethyl aluminum in these oxygen, moisture and the system will generate in the triethyl aluminum product that solid-state aluminum oxide enters production; Do not allow to contain any solid impurity in the final commodity of triethyl aluminum.These solids are removed by rectifying tower in technological process in the product.The process of removing is: make solid in rectifying, be accumulated in the bottom column still of triethyl aluminum rectifying tower, treat that concentration runs up to higher level, in the time of may influencing the normal operation of tower, discharge from the tower still, again behind standing demix, recovery part triethyl aluminum clear liquid, the raffinate after the recovery clear liquid has 1.5 times the triethyl aluminum that is about the solid impurity gross weight can't reclaim in traditional technology, to send incinerator to burn together with impurity, or send the hydrolysis kettle hydrolysis treatment.Therefore, the triethyl aluminum that is equivalent to aggregated capacity about 3% every year is burnt or hydrolysis, waste not only, and also it is bigger to topsoil to burn the back.
The utility model content
In view of the above-mentioned problems in the prior art, the utility model purpose is in the triethyl aluminum commercial process, and a kind of device that reclaims triethyl aluminum from produce raffinate is provided, and is significant in waste water utilization, save energy, protection environment.
The utility model is by adding a kind of cheap, high boiling, saturated hydrocarbon liquids that is worth in the triethyl aluminum raffinate, enter stirring tank, deep fat heating by chuck or coil pipe, carry out underpressure distillation, the triethyl aluminum steam that distills out is condensed into liquid through low temperature oil cooling matchmaker cooling, enters withdrawing can, send the product storage tank, be mixed into the commodity triethyl aluminum with device product.Distill out the liquid-solid mixed solution behind the triethyl aluminum, separate through filter, solid send incinerator to burn, and carries out harmless treatment, the liquid recycling.
Described triethyl aluminum retrieving arrangement is characterized in that this retrieving arrangement is connected in sequence by the pipeline that is provided with by mixing device, condensation reflux unit and withdrawing can.
Described triethyl aluminum retrieving arrangement is characterized in that described mixing device comprises that inside is provided with the stirring tank of agitator, and the outside socket of stirring tank tank body is provided with chuck, and stirring tank top is provided with raffinate opening for feed, fluid inlet and vapour outlet.
Described triethyl aluminum retrieving arrangement is characterized in that described condensation reflux unit comprises-35 ℃ of secondary coolers and 10 ℃ of one-level water coolers that connection is set together, and the condensation reflux unit top connects vacuum extractor.
Described triethyl aluminum retrieving arrangement is characterized in that being provided with in described-35 ℃ of secondary coolers-35 ℃ of pentanes and flows from the bottom up, 10 ℃ of cold oil is set in 10 ℃ of one-level water coolers flows from the bottom up.
Above-mentioned triethyl aluminum retrieving arrangement, compact construction, reasonable in design, simple to operate, easy to use, through the triethyl aluminum purity height that this device reclaims, this retrieving arrangement has good use value in suitability for industrialized production.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: the 1-withdrawing can; The 2-stirring tank; The 3-chuck; 4-raffinate opening for feed; 5-fluid inlet; The 6-vapour outlet; The 7-agitator; 8--35 ℃ of secondary coolers; 9-10 ℃ of one-level water cooler; The 10-vacuum extractor.
Embodiment
Now the utility model is described in further detail in conjunction with Fig. 1.Retrieving arrangement described in the utility model mainly comprises three parts: mixing device, condensation reflux unit and withdrawing can 1, wherein mixing device is made up of stirring tank 2, chuck 3, raffinate opening for feed 4, fluid inlet 5, vapour outlet 6, agitator 7, the raffinate that contains triethyl aluminum flows to stirring tank 2 bottoms from raffinate opening for feed 4 by pipeline, simultaneously, add a kind of high boiling, saturated hydrocarbon liquids (as white oil) by fluid inlet 5 and enter stirring tank 2, under the stirring of agitator 7, make it to mix with the triethyl aluminum raffinate.Stirring tank 2 outer setting have chuck 3, in the chuck 3 deep fat are housed.The triethyl aluminum that distills out enters condensation reflux unit by vapour outlet 6, enter 10 ℃ of one-level water coolers 9 and-35 ℃ of secondary coolers 8 successively, 10 ℃ of cold oil wherein are set in 10 ℃ of one-level water coolers 9 to flow from the bottom up,-35 ℃ of pentanes are set in-35 ℃ of secondary coolers 8 to flow from the bottom up, the condensation reflux unit top is provided with vacuum extractor 10, thereby make the liquid in the stirring tank 2 carry out underpressure distillation, the triethyl aluminum steam that distills out is condensed into liquid after low temperature oil cooling matchmaker cooling, enter withdrawing can 1, become the triethyl aluminum crude product, reach and be pressed into the ethene flash tank after a certain amount of, pump into rectifying tower by pump.Distill out the liquid-solid mixed solution behind the triethyl aluminum, separate through filter, solid send incinerator to burn, and carries out harmless treatment, the liquid recycling.
