[0002] In the chemical production process, the intermediate products are often involved in the process of centrifugation, separation, filtration, decolorization and other processes. The decolorization process is completed in the decolorization kettle. It is necessary to add the liquid to be decolorized and an appropriate amount of activated carbon, filter aid or decolorizer into the kettle body. After a certain period of stirring, it is filtered through the filter at the bottom of the kettle and discharged from the drain port.
