Description
Technical field
The utility model relates to triethylamine recovery process and equipment in a kind of glyphosate production process, and in particular to one kind
Triethylamine molecular sieve drying process and equipment belong to glyphosate production field.The triethylamine recovery process has can continuous metaplasia
It produces, the advantages of desiccant is reusable, device good leak tightness, safety and environmental protection.
Background technique
Catalyst of triethylamine uses 99% piece alkali in the drying process in glyphosate production, the use of equipment is that stirring-type is anti-
Kettle is answered, it is intermittent that triethylamine is dehydrated, then by manually putting into packed piece alkali in dehydrating kettle, dry 2-3
Sample detection moisture result is 0.2-0.3% after hour, and drying effect is poor.The higher triethylamine of water content, it is easy in synthesis phase
It is hydrolyzed and reacts with the dimethylphosphite of investment, cause glyphosate yield relatively low.
In addition, cast hopper need to be opened during adding piece alkali, and when pressure is higher in dehydrating kettle, the piece alkali water suction heat release of investment
Temperature in the kettle is caused to increase, triethylamine volatile quantity increases, and influences site work environment, endangers employee's health.
Simultaneously under low temperature environment, piece alkali absorbs water the high-concentration alkali liquor to be formed easily in equipment bottom crystal blocking pipeline, influences
Production stability.
The utility model be intended to provide in a kind of glyphosate production with serialization, the triethylamine recycling work of good leak tightness
Skill and device reduce fluctuation, improve site work environment, reduce Triethylamine gas to the body harm of employee.
Summary of the invention
Triethylamine recovery process in existing glyphosate production process is mainly intermittent operation, production cycle length and device
Airtightness is poor, exists simultaneously the shortcomings that pipe plugging by crystallization leads to fluctuation, it is raw that the utility model is intended to provide a kind of glyphosate
The serialization of production process, the triethylamine recovery process of good leak tightness and equipment reduce fluctuation, improve site work environment,
Triethylamine gas is reduced to the body harm of employee, reduces security risk.
The utility model is specifically related to the triethylamine recyclable device in a kind of glyphosate production process.First triethylamine point
Layer slot is connect with the second triethylamine layering slot, and the second triethylamine layering slot is connect through pipeline with level-one drying tower, level-one drying tower
Bottom is connect through pipeline with secondary drying tower, and secondary drying tower bottom is connected to triethylamine finished product storage tank through pipeline.Level-one is dry
Tower is connected to triethylamine device for absorbing tail gas through pipeline with secondary drying top of tower.Level-one drying tower is set with secondary drying tower bottom
It is equipped with dry hot-air intake pipeline.
1, technique and device brief introduction
The mother liquor generated during glyphosate is sufficiently neutralized by mixer with liquid alkaline, triethylamine, water after neutralization
Equal mixed liquors enter triethylamine layering slot, because triethylamine specific gravity is smaller, into layering slot after it is static, the triethylamine isolated from point
Layer groove top portion's overflow goes out, and through stationary groove secondary clearing again, obtained aqueous triethylamine is then again by equipped with molecular sieve filling
Drying device is dehydrated, and controls drying tower produced quantity and regurgitant volume, the lower triethylamine finished product of obtained water content is for following
Ring production, specific molecular sieve drying device quantity are actually designed according to production, see attached drawing 1.
Beneficial effect
The triethylamine recovery process replaces piece alkali to be dried using molecular sieve desiccant, not only effective solution interval
The shortcomings that formula produces, while tower type drying device is used, avoid environment, personnel health and safety and environmental protection that piece alkali adds process
Problem reduces fluctuation, improves site work environment, reduces Triethylamine gas to the body harm of employee, improves life
Produce safety.
Detailed description of the invention
Fig. 1 be=glyphosate production process in triethylamine dried recovered structure drawing of device, wherein 1. first triethylamines layering
Slot, 2. second triethylamines are layered slot, 3. level-one drying towers, 4. secondary drying towers.
Specific embodiment
Embodiment 1
Triethylamine dried recovered device in a kind of glyphosate production process, the first triethylamine are layered slot 1 and the second triethylamine
Slot 2 is layered to connect, the second triethylamine layering slot 2 is connect through pipeline with level-one drying tower 3,3 bottom of level-one drying tower through pipeline and
Secondary drying tower 4 connects, and 4 bottom of secondary drying tower is connected to triethylamine finished product storage tank through pipeline.The level-one drying tower 3 with
4 top of secondary drying tower is connected to triethylamine device for absorbing tail gas through pipeline.The level-one drying tower 3 and secondary drying tower 4
Bottom is provided with dry hot-air intake pipeline.
During triethylamine of the present invention is dry, using centrifugal pump by the glyphosate crystal liquid pump settled into crystal solution
And mixer, it is sufficiently mixed with liquid alkaline after reacting, the mixtures such as obtained triethylamine, water enter triethylamine layering slot, layered
After the abundant static layering of slot, the triethylamine isolated is overflowed from layering slot top, is then transferred to molecule by triethylamine transfering material pump
It sieves at the top of drying tower, is dispersed into drying tower packing layer through redistributor at the top of drying tower and carries out overflow drying, control triethylamine
Extraction, reflux ratio, the qualified triethylamine of extraction enter finished product storage tank for recycle production.
And used desiccant is also renewable, it is empty using dry heat according to triethylamine discharging moisture situation after drying
Agent regeneration is dried in gas.Concrete operations are：Triethylamine drying tower inlet valve is closed, triethylamine in drying tower is emptied, is opened dry
Agent regeneration is dried by dry hot-air in dry tower hot-air valve and emptying pipe valve, controls dry hot air temperature at 110 DEG C
The gaseous mixture of left and right, the triethylamine, water that steam is absorbed using acid medium tail gas absorbing system, controls absorbing liquid concentration,
After absorbing liquid reaches requirement concentration, absorbing liquid is adopted and recycles triethylamine into crystal solution system, it is ensured that site environment.
