Liquid disperser for small extraction tower and small extraction tower

The invention provides a liquid disperser for a small extraction tower and the small extraction tower. The liquid disperser for the small extraction tower comprises a distribution plate and a barrel arranged on the distribution plate, the distribution plate is of an annular structure, a plurality of dispersion holes penetrating through the distribution plate are formed in the distribution plate, and the inner ring edge of the distribution plate is connected with the upper end of the barrel. Compared with the prior art, the liquid disperser for the small-sized extraction tower provided by the invention has the advantages that the liquid dispersion effect meets the dispersion requirement of a packed extraction tower, the adaptability to flow change is high, and the disperser is simple in structure, low in manufacturing cost and convenient to install and use, and can be installed and used in the small-sized packed extraction tower; the zigzag notch is formed in the lower end of the barrel, so that when the flow
