The refined chemical grade isoprene that can just obtain 98% or more purity.The essence of the rectifier unit needed in the process in the prior art
Form of the tower using filling filler in traditional tower body is evaporated, although the material that this form enters can be flowed into the hot gas of rising
The instant heat exchange of row, but the gas composition regurgitant volume that rectifying goes out is big, rectification efficiency is relatively low, and can carry certain heavy constituent
It is discharged from tower top, reduces product quality.
Utility model content
The technical problems to be solved in the utility model is：It is high to overcome the deficiencies of the prior art and provide a kind of rectification efficiency
The low reflux weight-removing column of thick isoprene.
Technical solution adopted by the utility model to solve its technical problems is：The low reflux weight-removing column of the thick isoprene,
Including weight-removing column tower reactor and weight-removing column tower body, it is characterised in that：An inner tube, inner pipe-through are equipped in the weight-removing column tower body
Weight-removing column tower body is divided into inner cavity and exocoel by the upper and lower ends of weight-removing column tower body, inner tube, and inner cavity is inner tube and weight-removing column tower body
Between chamber, exocoel be inner tube on the inside of chamber；The top of weight-removing column tower body opens up the feed(raw material)inlet of connection exocoel, inner cavity
Top offers light fraction outlet, and wherein exocoel inside spin coiling is equipped with deflector；The downside of the junction of deflector and inner tube
Offer venthole.
The inner tube of the utility model up and down, can ensure the isoprene light component to have gasified smoothly to tower top
It collects, and heat exchange instant between the interior exocoel of tower body during rising, make a part of isoprene in outer intracavitary raw material
Make the heavy constituent of interior intracavitary liquefy while gasification to flow back.Outer intracavitary raw material slowly flows down along the deflector of spiral increases heat exchange
Amount.The utility model can ensure the amount of the isoprene of gasification while realizing raw material and gasifying component heat exchange, improve essence
Evaporate efficiency.
The inner tube is calabash shape.The ascending air of inner cavity can be made to form turbulent flow, to improve the heat exchange of interior exocoel
Efficiency.
The outer of the deflector is sloped downwardly.The raw material flowed on deflector can be made more to disperse, reduce and formed
Line increases heat exchange efficiency.
The venthole is in outer intracavitary and is equipped with liquid capture grid.Prevented liquid carry heavy constituent enter inner cavity and
Influence product quality.
The outer wall of the inner tube is equipped with cooling fin.The effective heat exchange efficiency for improving interior exocoel.
Compared with prior art, advantageous effect possessed by a kind of low reflux weight-removing column of thick isoprene of the utility model
It is：It is in calabash shape that the tower body of this weight-removing column, which has inside and outside two tube chambers, inner tube set, is the current limliting of coiled coil in the tube chamber of outer tube
Plate；The junction of current limiting plate and inner tube, opens up venthole on the downside of current limiting plate, enters isoprene inner tube, current limliting for gasification
Plate is sloped downwardly outside, and heavy constituent and unvaporized isoprene mixing liquid flow into tower reactor along outer.What guarantee was thermally formed
Gas isoprene light component, will not be in direct contact in uphill process with liquid, air-flow climbing speed be improved, to reduce liquid
Change the amount of the gas isoprene of reflux, while ensureing product quality, improves rectification efficiency.
