Description
Technical field
The present invention relates to technical field of chemical, and in particular to a kind of high effect of reducing pressure concentration tower.
Background technology
Solvent of the dimethylformamide (DMF) as important industrial chemicals and function admirable, dimethylformamide was both
It is a kind of extremely wide industrial chemicals of purposes, and a kind of excellent solvent having many uses, in organic reaction, dimethyl formyl
Amine is widely used as the solvent of reaction, but often encounters solvent and take off not only, furthermore it can be with miscible with water, and boiling point is higher than water, letter
It is difficult dehydration that single recycling design method, which is, if regardless of expense is just washed with water, DMF has certain toxicity in addition, in DMF
When storage tank stores, because DMF finished products, waste liquid are going out tank, entering tank or when outside air temperature raises, have a small amount of DMF volatilization and storing up
Around tank, the wasting of resources can be caused, has an effect on environment, endangers personnel health, there is very big potential safety hazard.
Need to design a set of DMF gas concentration units simple in construction, easy to make, cost is cheap, it is easily molten using DMF
In the characteristic of water, fully absorb DMF gases and recycled, both solve environmental problem, reduce potential safety hazard again, also
The means of production are saved.
The tower that is concentrated under reduced pressure is needed in DMF gas concentration units, the tower that is concentrated under reduced pressure used at present has production cost mistake more
Height, the problems such as installation and maintenance complexity, normal production is have impact on, reduces production efficiency.
The content of the invention
The invention aims to overcome deficiency of the prior art, there is provided a kind of production for DMF recovery systems
The tower that is concentrated under reduced pressure that cost is low, production efficiency is high, gas-liquid separation effect is good, concentrated effect is good.
In order to solve the above technical problems, the technical scheme is that：
A kind of high effect of reducing pressure concentration tower, including concentration tank, the first condenser, gas-liquid separator, the second condenser being sequentially communicated
And fluid reservoir, the concentration tank include tank body and journal stirrup, the journal stirrup is located at the middle part of tank body, stirring is provided with the tank body
Axle, agitating paddle is arranged with the agitating shaft, motor, output shaft and the agitating shaft axle company of the motor are provided with the top of the tank body
Connect, be provided with Butterworth Hatch, charging aperture and steam (vapor) outlet at the top of the tank body, the tank base is provided with discharging opening, in the tank body
Portion is provided with refluxing opening；The separator includes isometrical cylindric body, the body two side ends be respectively equipped with gas-liquid arrival end and
Gas circuit output end, the body are fixed with screw shaft, the spiral shell of the screw shaft close to gas-liquid upstream end pore inside line
Vane piece external diameter surface closes cooperation closely with inboard wall of tube body face, is offering feed liquid output end on the downside of body on position.
Compared with prior art, beneficial effects of the present invention are：（1）Reasonable in design, simple in construction, easy to process, installation
It is easy to maintenance, production cost is low, production efficiency is high, concentrated effect is good；（2）Gas-liquid separation effect is good, separative efficiency is high, separation work
Skill is simple, operation is reliable.
