Title:
AUTOCLAVE AND METHOD FOR REMOVING SALTS FROM AUTOCLAVE
Document Type and Number:
WIPO Patent Application WO/2019/135442
Kind Code:
A1
Abstract:
The vertical autoclave according to one embodiment of the present invention, which has an injection port via which processing liquid is injected, a discharge port via which the processing liquid is discharged, an oxygen injection port for supplying oxygen to the processing liquid, a stirrer for mixing the processing liquid, and an inner wall, comprises: an acid-resistant brick layer lining the lower and side parts of the inner wall; and an acid-resistant metal layer lining the upper part of the inner wall. In addition, the method for removing salts inside an autoclave according to one embodiment of the present invention comprises: increasing the surface level of a solution portion from a first level to a second level so that salts inside an autoclave are immersed in the solution portion; and maintaining the surface level of the solution portion at the second level, wherein the salts are dissolved into the solution portion while the surface level of the solution portion is maintained at the second level.
