Solvent Refining Tower

1.The main body of the equipment is polished stainless steel frame structure, beautiful appearance;

2.The whole tower is set with three glass observation cups, easy to observe the gas-liquid contact and operation inside the tower;

3.The operation interface is wide and can be operated by several students;

4.Using low-noise dosing pump, no influence on teaching indoors;

5.Tower top effluent can be directly in the top of the tower composed of wine tester for concentration determination, easy to operate;

6.The use of ethanol water system, raw materials, low price, easy to obtain and non-toxic;

7.Simple operation and maintenance.

Ⅰ.Full reflow

1. to understand the characteristics of the full reflux operation. understand the full reflux in the actual production of the guiding significance;

2. can be full reflux operation training.

Ⅱ.Partial reflux

1. to understand some of the characteristics of reflux operation. to understand the whole tower theoretical number of plates and the determination of the efficiency of the whole tower;

2. to understand the reflux ratio on the efficiency of the whole tower;

3. to understand the reflux ratio. raw material feed. kettle residual liquid and heating voltage on the operation of the impact.

Ⅲ.Tower body set up three observation cups. can be observed separately on the distillation section. distillation section and sensitive plate gas-liquid contact situation

Ⅳ.Comparison of different raw material composition can be carried out double sideline feeding

Ⅴ.Non-normal operation processing

 1.Liquid leakage: how to judge according to the instrument tower plate leakage and affect normal operation. how to correctly dispose of;

 2.Liquid flooding: how to judge the tower liquid flooding. how to correctly dispose of;

 3.Sensitive plate temperature rises sharply: how to correctly dispose of;

 4.Sensitive plate temperature remains high: how to correctly dispose of;

 5. The tower top temperature is high: how to correctly dispose of;

 6. The tower kettle temperature is high: how to correctly dispose of;

 7. The kettle level is not normal: what will cause the consequences. how to properly dispose of
