Two-stage heavy oil slurry-bed reactor hydrogenation equipment and an application method thereof are disclosed. The equipment comprises a first slurry-bed reactor, a first separating unit, a second slurry-bed reactor and a second separating unit. The slurry-bed reactor comprises a riser tube (1) and a downcomer (8). A splitter plate (10) is arranged inside the downcomer (8) to divide the internal space of the downcomer into two parts which are communicated up and down and separated in the middle. The upper part of the riser tube (1) and one side of the two space parts of the downcomer are communicated through an upper connecting pipe (7). The lower part of the riser tube (1) and the bottom of the downcomer (8) are communicated through a lower connecting pipe (15). The other side of the two space parts of the downcomer (8) is provided with a product outlet. The bottom of the riser tube (1) is provided with a raw material inlet. Tops of the riser tube (1) and the downcomer (8) are respectively provided with gas
