Detailed description of the invention
For a better understanding of the present invention, below in conjunction with specific embodiments and the drawings, the present invention is conducted further description.
As shown in Figure 1-2, a kind of experiment esterification assembly comprises liquid storage cylinder 7, the lower end of described liquid storage cylinder 7 is fixedly connected with disengagement chamber 2, described liquid storage cylinder 7 end near described disengagement chamber 2 is provided with reducing, the upper end of described liquid storage cylinder 7 is provided with condenser pipe beam ground 8, the described liquid storage cylinder 7 being positioned at described condenser pipe beam ground 8 bottom is fixedly connected with tracheae 9, cooling coil 5 is also provided with in described liquid storage cylinder 7 on described between tracheae 9 and described thermometer boss 3, the bottom of described disengagement chamber 2 is provided with plug valve 1, the top of described disengagement chamber 2 is provided with liquid return tube 10, described upper tracheae 9 end and described liquid return tube 10 end are all connected with a distillation cascade is through, the end of described distillation cascade is provided with cucurbit beam ground 11.
This design by the distillation system in cucurbit 12 through adding thermogenetic mist successively through described cucurbit beam ground 11, described upper tracheae 9, described condenser pipe beam ground 8, described liquid storage cylinder 7 is flow back into after becoming liquid after entering reflux condenser 13 condensation, cooled by described cooling coil 5 and be separated gradually, blending ingredients enters in described disengagement chamber 2 through described reducing water conservancy diversion and continues to be separated, the heavy component such as water discharges separation by described plug valve 1, and the component of the light specific gravities such as dehydrated solvent again flows back to cucurbit 12 through described liquid return tube 10 and continues circulation..
Secondly, because refluxing opening is arranged on the bottom of described liquid storage cylinder 7, described mixing material is cooled naturally slowly sink and be separated gradually afterwards by described cooling coil 5, and stir because the phegma not having ascending air and described reflux condenser 13 to fall impacts, described mixing material can fully be separated.Finally, described liquid return tube 10 makes described dehydrated solvent be back to smoothly in cucurbit 12 with the design of described upper tracheae 9 non-common, and then improves separating effect.
The described liquid storage cylinder 7 being positioned at described disengagement chamber 2 top is provided with thermometer boss 3.This design, mainly for the ease of checking and controlling separation temperature, provides safeguard for improving separating effect.
The lower end of described cooling coil 5 is provided with coil pipe cooling water inlet 4, and the upper end of described cooling coil 5 is provided with coil pipe coolant outlet 6.This design mainly makes described liquid storage cylinder 7 burst the generation of phenomenon because being heated inequality in order to the described mixing material quenching preventing temperature higher.Described coil pipe cooling water inlet 4 and coil pipe coolant outlet 6, connect for convenience of sebific duct, adopt trapezoidal water nozzle form joint.
The port of export of described liquid return tube 10 is inclined upwardly, and the vertical projection height of described liquid return tube 10 is greater than the height of described cooling coil 5.This design ensure that described mixing material can have higher liquid level in described liquid storage cylinder 7; Because described cooling coil 5 is surrounded on described mixing material periphery, so effective cooling can be carried out to described mixing material make its solubility reduction because temperature reduces, and then layering, enhance separating effect; In addition, when described mixed gas flow strengthens, if there is the component be not separated completely on a small quantity, can continue to be separated in described liquid return tube 10.
In order to improve the universality of described experiment esterification assembly so be set to multiple by the model of described condenser pipe beam ground 8, and be also multiple by the type kind of described cucurbit beam ground 11.Wherein, described condenser pipe beam ground 8, adopts 19 mouthfuls, 24 mouthfuls, 29 mouthfuls, 32 mouthfuls, 40 mouthfuls, 50 mouthfuls of standard, is conveniently connected with the standard mouth of described reflux condenser 13; Described cucurbit beam ground 11, adopts 19 mouthfuls, 24 mouthfuls, 29 mouthfuls, 32 mouthfuls, 40 mouthfuls, 50 mouthfuls of standard, is conveniently connected with the standard mouth of described cucurbit 12.
