Description
Technical field
N-(β-aminoethyl)-γ-aminopropyltrimethoxysilane rectifier unit, belongs to chemical industry rectifying device field.
Background technology
In existing N-(β-aminoethyl)-γ-aminopropyltrimethoxysilane product coarse liquid, component is more and composition is more complicated, this just purifies and proposes high requirement product, be that the festival-gathering of rectifying still tower is higher, about 10 ~ 15 meters, during rectifying, in tower, vapour locking is larger, the rectifying time is longer, especially in the rectifying later stage, in still, material is surplus 1/3 o'clock, because tower joint is higher, the deficiency of evaporation capacity, product rate of withdrawal is slower, make feed liquid high-temperature heating overlong time in still can cause N-(β-aminoethyl)-γ-aminopropyltrimethoxysilane self that polycondensation reaction can occur, also can cause rectifying still too much remaining, rectification yield is low, consume high, cost is high.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of rectifying fast, consume low a kind of N-(β-aminoethyl)-γ-aminopropyltrimethoxysilane rectifier unit.
The utility model solves the technical scheme that its technical problem adopts: this N-(β-aminoethyl)-γ-aminopropyltrimethoxysilane rectifier unit, the rectifying column that comprises rectifying still and rectifying still top, it is characterized in that: described rectifying still top is equipped with destilling tower, destilling tower top pipeline is connected with condensation receiving system; Destilling tower and rectifier bottoms and rectifying still junction are equipped with controls the steam cock that can steam enter.
Described condensation receiving system is the distillage receiving tank that distillation column condenser is connected with distillation column condenser pipeline.
Described rectifying column top pipeline is connected with rectifying column condenser, and rectifying column condenser pipe is connected with gas-liquid separator, and gas-liquid separator connects rectifying product receiving tank more by the road.
Described rectifying still is provided with the temperature regulating device of steam and recirculated water.
On the equipment of former rectifying still, installed destilling tower and the condensation receiving system of 2 ~ 3 meters additional a set of, in destilling tower, without filler, in the rectifying later stage, in still, material is surplus 1/3 o'clock, open destilling tower, because tower joint is lower, in tower, without filler, evaporation vapour locking is less, in still, material can preferentially be steamed by this tower, its product rate of withdrawal is very fast, and final products distillation required time has shortened greatly, has avoided feed liquid high-temperature heating overlong time self in still that polycondensation can occur.
Compared with prior art, the beneficial effect that N-of the present utility model (β-aminoethyl)-γ-aminopropyltrimethoxysilane rectifier unit has is: the utility model is on the equipment of former rectifying still, to have installed a set of destilling tower and condensation receiving device additional, tower is interior without filler, in the rectifying later stage, open new clothes destilling tower, because tower joint is lower, tower is interior without filler, evaporation vapour locking is less, in still, material can preferentially be steamed by this tower, its product rate of withdrawal is very fast, final products distillation required time has shortened greatly, avoided feed liquid high-temperature heating overlong time self in still that polycondensation can occur, reduced like this rectifying still residual, rectification yield uprises, consume and reduce, cost.The utility model can shorten industrial rectifying and produce the needed time, has improved the yield of product, has reduced cost, and significantly reduces and produce required energy consumption, has improved device fabrication power.
