Abstract

A crystallization column and a crystallization method. The crystallization column comprises an upper head (1), a tower body (2) and a lower head (3), wherein a crystallization section (11) is provided with a tray (14); and the tray (14) comprises a tray plate (15) and a plurality of lower crystallization members (17). The top end of the lower crystallization member (17) can form a movable connection with the tray plate (15), so that the two adjacent lower crystallizing members (17) are capable of oscillating collisions. The tray (14) may also comprise a plurality of upper crystallization members (21) extending upwardly from the upper surface of the tray plate (15).
