The utility model relates to an anti-blocking grid packing unit and an extraction tower. The anti-blocking grating packing unit comprises a plurality of grating plates and distance fixing rods. The grating plate comprises packing sheets. The multiple packing sheets are arranged in parallel at intervals in the first direction. A plurality of guide holes are formed in each packing sheet at intervals in the second direction. In the third direction, a first tongue piece and a second tongue piece are arranged at the two opposite positions of the edge of each guide hole respectively. A limiting part is arranged at the position, opposite to each packing sheet, of the distance fixing rod, so that the mounting position of each packing sheet in the first direction is limited. And the first tongue piece and the second tongue piece are inclined plates which are obliquely arranged relative to the packing piece. In each grating plate, the inclination directions of any two adjacent first tongue pieces are opposite, and the
