Filler distillation tower training desk

1. The entire device is beautiful, the structure is reasonable, and the overall sense is strong, which can fully reflect the concept of modern experimental devices.

3. The equipment is a self -propelled frame structure, and the feet are installed to facilitate the disassembly m--ntenance and handling of the system.

4. The m--n body, condenser and storage tank are made of 304 st--nless steel. The process is fine and well -made.

5. The feeding solution and the tower kettle residue are changed to achieve the use of waste heat reuse, which reflects the full use of the concept of engineering.

6. Manual and automatic ways to accurately control the return ratio, which can achieve full return and partial return operations.

7. Use the clever design of the structure to control the tower liquid level to avoid dried heat heater.

8. Device design can be observed at 360 degrees to achieve comprehensive teaching and experiments.

Device function:

1. Understand the basic structure and working principle of the experimental device of the filler, and master its operation methods;

2. The tower body is transparent and visible, and the working status of the tower can be observed;

3. The feeding can be exchanged with the tower liquid heat to achieve waste heat reuse;

4. The backflow ratio can be automatically controlled, observing the effects of the system temperature stability at the system temperature stability;

1. Function summary
