FIELD: chemistry.SUBSTANCE: invention relates to chemical crystallisation equipment for gas-phase reactions, in particular, reaction of two gases to obtain a solid phase. Crystallization column includes top head 1 with gas outlet hole 4, housing 2 and lower head 3 with gas inlet 8 and material outlet 7, housing 2 comprises crystallization section 11 equipped with plates 14 including tray plate and plurality lower crystallisation elements. Upper end of the lower crystallisation element can form a movable connection with the tray plate, so that two adjacent lower crystallisation elements can collide during oscillation. Plate 14 may also include a plurality of upper crystallisation elements extending upward from the top surface of tray plate.EFFECT: crystallization column is simple in structure, has low cost, high efficiency of crystallization and provides easy crystallization of crystalline substances.28 cl, 6 dwg, 1 tbl, 2 ex |
