Detachable scale deposition preventing tool for nickel oxide slurry slurry sickness overflow flow and its scale deposition preventing method

摘要

Problem to be solved: to examine the substance and the method of giving the chemical resistance and the smoothness on the surface of the liquid at the gas-liquid interface of the overflow knickers in the shickner apparatus, and the material which is excellent in chemical resistance and smoothness is used, and it is possible to install it appropriately in the necessary place, and the generation of the precipitate, is carried out. Provides a removable scale deposition preventing jig to prevent growth.Solution: a scale deposition preventing jig which prevents scale deposition of the gas liquid interface and the overflow of the overflow liquid on the inner surface of the overflow liquid in the gas-liquid interface used for the separation process of the slurry, and the gas-liquid interface of the overflow sluice is Located on the upper surface of the wall of the overflowThe scale deposition preventing jig has a groove sandwiching the upper surface of the overflow wall which is the gas-liquid interface from above A desolation scale deposition preventive tool for nickel oxide slurry slurry sickness overflow flow which is characterized by including a resin material excellent in chemical resistance and smoothness having a form which is easy to remove and fix.Diagram
