The invention relates to a tantalum powder preparation device and a tantalum powder preparation method. The tantalum powder preparation device comprises: a reaction container, in which a vessel is arranged, the vessel is used for containing materials for preparing tantalum powder, and the materials comprise tantalum oxide and magnesium powder; the collector is arranged in the reaction container, the collector comprises a top wall, a bottom wall and a circumferential side wall connected with the top wall and the bottom wall, the bottom wall covers the upper part of the vessel and is provided with a plurality of first through holes, the top wall is provided with a second through hole communicated with an evacuation pipeline, and the bottom wall is provided with a plurality of second through holes communicated with the evacuation pipeline. The collector is configured to collect magnesium vapor entering the collector through the plurality of first through holes. The residual excessive magnesium in the material is collected by the collector, so that the magnesium content in the final tantalum powder product can be obviously reduced, and the purity of the tantalum powder and the performance stability of the product are improved. And moreover, the metal magnesium collected by the collector can be recycled after being purified, so that the reutilization of resources is realized, the consumption of raw materials is reduced, and the potential pollution of magnesium-containing wastes to the environment is reduced.
