Description
Technical field
The utility model belongs to technical field of chemical, is specifically related to the system that a kind of solvent method refines captax.
Background technology
Thiofide MBT (MBT), be called for short M, the universal promotor of widely used one in rubber industry, it is the product that thiofide volume of production and marketing is maximum both at home and abroad at present, it is the raw material of the promotor such as sulfenic acid amides, DM class simultaneously, market demand is larger, and apparent availability is more nervous.High-content M still produces the main raw material of cephalosporin analog antibiotic medicine.But high-pressure synthesis M purity is out low, containing plurality of impurities (being referred to as resin), can not directly use.Therefore, the refining purification process of M becomes a very important step in its production.
The production method of current domestic 2 Mercaptobenzothiazole (MBT) has two kinds: one to be soda acid WATER-WASHING METHOD; Two is solvent extrations.Soda acid WATER-WASHING METHOD is current domestic the most frequently used process for refining and purifying, accounts for dominant position.The method will consume a large amount of strong acid, highly basic and water, produces the high density saliferous organic basic waste water that product per ton can produce more than 45 tons, aftertreatment difficulty.Solvent extration is process for refining and purifying more novel at present.Along with the increasing of environmental protection dynamics, solvent extration refines purification techniques and anhydrous process, is more and more subject to people's attention.Now along with Environmental Protection Situation is increasingly severe, captax, because wastewater flow rate is large, waste water is difficult to be processed into the bottleneck developed to restrict it, becomes extremely urgent task so how to address this problem.
Utility model content
For problems of the prior art, the utility model provides a kind of solvent method to refine the system of captax, fully achieves the discharge without processing wastewater, belongs to environmental protection process system.
For solving the problems of the technologies described above, the utility model provides following technical scheme:
A kind of solvent method refines the system of captax, comprise dissolution kettle, described dissolution kettle is connected with standing tank I, leave standstill tank I to be connected with extraction kettle, be connected with dithiocarbonic anhydride test tank by pipeline above described extraction kettle, extraction kettle is connected with filtration unit I, be connected with steaming carbon tower by pipeline below filtration unit I, steam carbon tower to be connected with filtration unit II, filtration unit II is connected with moisture eliminator, be connected with standing tank II by pipeline above filtration unit I, leave standstill below tank II and be connected with concentration tank, leave standstill above tank II and be connected with steaming water pot, steam water pot respectively with dissolution kettle with steam carbon tower and be connected.
Described steaming carbon tower is connected with dithiocarbonic anhydride storage tank, and described dithiocarbonic anhydride storage tank is provided with cooling sandwith layer.
Hutch water device is provided with above described steaming carbon tower.
Be connected with standing tank I by pipeline above described filtration unit II.
Be connected with resin pool below described standing tank I, leave standstill above tank I and be connected with tank.
Described concentration tank is connected with dithiocarbonic anhydride storage tank.
The beneficial effects of the utility model: adopt solvent method of the present utility model to refine the system of captax, high pressure resultant and ethylene glycol are being placed in dissolution kettle, make resultant entirely molten, after being transferred to the cooling of standing tank I, drip, stratification, lower-layer resin reclaims as in resin pool, supernatant liquor being placed in extraction kettle adopts ice-water bath cooling down to separate out M, adds CS
2, room temperature extraction 1h, then enters filtration unit I filtration, and the filter cake making beating that adds water is placed on the CS steaming carbon tower and add heat abstraction material clamp band
2, suction filtration, washing, dry M; Filtrate stratification, mother liquor simple rectifying in upper strata is removed moisture Posterior circle and is used, lower floor CS
2distillation and concentration reclaims unnecessary CS
2, residue CS
2residue drops into reuse in autoclave, decreases distillation power consumption, achieves recycling of ethylene glycol mother liquor, decreases distillation power consumption, reduces energy consumption, fully achieve the discharge without processing wastewater, belong to environmental protection process system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
