Zusammenfassung:	The invention relates to a rinsing method and device of a potassium fluotantalate product obtained through sodium reduction. The rinsing method comprises the following steps: using sodium to reduce potassium fluotantalate and obtain coagulum, crushing the coagulum, diafiltrating, rinsing, stirring to rinse, pickling, and drying to obtain raw tantalum powder. The obtained tantalum powder has high purity and good porosity and can be used to prepare condensed tantalum powder which is particularly suitable for the manufacture of the electrolytic capacitor.
