Claims12
A cooling device for a sublimation section is characterized in that, comprising a reaction kettle provided with a smooth inner wall, a top of the reaction kettle is provided with a gas phase port, a bottom of the reaction kettle is provided with a discharge port, a middle of the reaction kettle is provided with a sublimation gas phase inlet, and a wall of the reaction kettle is further provided with a jacket.
A cooling method for sublimation section is characterized in that, comprising the following steps:
- Step 1:
- vacuumizing a reaction kettle to ensure that vacuum degree in the reaction kettle is −0.08 MPa˜−0.095 MPa;
- Step 2:
- introducing the sublimated material in gas phase directly into the reaction kettle through a gas phase inlet;
- Step 3:
- condensing the sublimated material in gas phase into solid material in the reaction kettle.
