Abstract
The utility model discloses a kind of Novel visual sieve plate distillation column teaching experimental equipment, rectifying column tower body is saved by clear polycarbonate material tower and assembles, and tower joint is the Sealed sandwich structure of inside and outside wall, and two wall interlayer seal clearance layers are air or vacuum shape.The utility model uses Merlon to be tower body main material, the cost of manufacture of teaching experimental equipment is reduced, visual being beneficial to of equipment tower body observes each situation of gas-liquid mass transfer in tower body, be convenient to the stable operation in education experiment process, also effectively can avoid or demonstrate phenomenons such as carrying liquid flooding, overflow liquid flooding, leakage secretly.In addition, the sandwich of tower body can provide good Insulation for rectifying separation system.
Description
Technical field
The utility model relates to a kind of teaching experimental equipment, particularly relates to that a kind of teaching demonstration performance is good, separative efficiency is high, the Novel visual sieve plate distillation column teaching experimental equipment of insulation and high, the easy to control operation of mass transfer stability.
Background technology
Distillation operation unit is the priority and difficulty content of Principles of Chemical Engineering, thus invents a kind of teaching experimental equipment, is vividly demonstrated out for understanding this part abstract theory significant intuitively.At present, what traditional sieve plate distillation column teaching experimental equipment adopted is stainless steel material is the tower structure equipment of main body, and equipment manufacturing cost is higher.Tradition rectifying column education experiment tower body adopts the insulation material such as asbestos, glass fibre usually, outer stainless steel parcel, and whole equipment is in closed state, and equipment is also difficult to dismounting and installs after being in operation and breaking down, maintenance exists larger difficulty.
In education experiment process, traditional sieve plate rectifying tower body not visible, the inevitable blindness operation occurring " camera bellows " formula, makes distillation operation often restive.Tradition rectifying device not visible, the non-steady state operation contents of courses such as carrying liquid flooding, overflow liquid flooding, leakage secretly can not be demonstrated in experimental teaching.Though there is the appearance of glass material rectifying column, but its there is processing difficulties, be easy to broken, many drawbacks such as crushing resistance is poor, heat-insulating property is low, limit the popularization in rectifying education experiment.
Utility model content
For the problems referred to above, the utility model proposes a kind of Novel visual sieve plate distillation column teaching experimental equipment, there is intuitively visual, economical rationality, easy to maintenance, separative efficiency is high, operation is easy to the features such as control.
For achieving the above object, the utility model adopts following technical proposals to realize:
This visual sieve plate distillation column experimental facilities mainly comprises tower reactor, tower body, condenser etc.Described tower reactor supplying heat source is PID temperature control heating by electric cooker system; Described tower body is that the tower joint of double sandwich transparent tube body structure is formed, fixed by Flange joint and the segmentation structure that formed realizes, the transparent cylindrical shell of described double sandwich is that makrolon material is made, and double sandwich transparent tube interlayer body thickness is 0.8cm, and clearance layer is air or vacuum shape; Described condenser is connected with tower top discharging opening, condensing reflux mouth, borrow mouth respectively by pipeline.
The utility model has following remarkable advantage: the separative efficiency of full tower effectively improves, and the visual tower joint package assembly of full tower body, is convenient to the problem investigation under long-play equipment fault situation, is beneficial to and removes and installs and keep in repair.Tower body adopts Merlon material that the cost of manufacture of teaching experimental equipment is reduced greatly, and double sandwich structure makes whole tower body heat insulating ability significantly improve, and is beneficial to the raising of equipment rectification efficiency.The visuality of the whole tower body of equipment, on the one hand in rectifying experiment process, the blindness " camera bellows " of student can be effectively avoided to operate, the stable operation that easily can realize distillation process controls, on the other hand in experimental teaching, teacher can demonstrate to student within the scope of full tower body for the wild effect of distillation operation visual pattern, is beneficial to the intuitivism apprehension of student to the operation of rectifying instability.

Detailed description of the invention
The utility model is illustrated below in conjunction with embodiment.
As Fig. 1,2, shown in 3, a kind of Novel visual sieve plate distillation column teaching experimental equipment, comprises tower reactor 1, tower body 2 and condenser 3.The tower joint that described tower body 2 is consisted of the transparent cylindrical shell 5 of double sandwich, is connected and fixed by flange 4 and assembles, and sieve plate 6 is put in tower joint lower end.Described condenser 3 is connected with tower top discharging opening, condensing reflux mouth, borrow mouth respectively by pipeline.
Example is separated into the rectifying of 20% (v/v) alcohol-water system.20% (v/v) ethanol-water solution is injected tower reactor 1, arrives regulation liquid level, then heat tower reactor 1, meanwhile cooling water is sent in condenser 3.The gas-liquid mass transfer phenomenon of tower body 2 inside can be observed because tower body 2 is visual, can unsteady mass transfer phenomenon in Timeliness coverage tower, according to operation factors such as the adjustment of tower inner transmission matter situation inlet amount, reflux ratio, heating powers.In rectifying separation process, rectifying can be adjusted to stable mass transfer conditions easyly.In experimentation, liquid in tower reactor 1 and overhead product extraction are analyzed its concentration by timing.After situation of seething with excitement in still pressure, still temperature and tower is stable, concentration can be obtained by tower top thief hatch and be about 95% (v/v) ethanol.In addition, visual due to full tower body, can demonstrate the astable mass transfer that operation lack of standardization causes within the scope of full tower, as tuned up heating power, reducing reflux ratio, the liquid flooding that the entrainment produced causes, the teaching demonstration performance of equipment is high.
20% (v/v) alcohol-water system of the above rectifying column teaching experimental equipment is separated and is only preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
