Box plate type crystallizer for purifying vinylene carbonate

The utility model relates to the field of crystallizers, and discloses a box plate type crystallizer for vinylene carbonate purification, which comprises a crystallizer box body, a crystallization plate group is arranged in the crystallizer box body, the crystallization plate group comprises at least one crystallization plate, a cavity for accommodating cold/hot media is arranged in the crystallization plate, a baffle plate is fixed on the crystallization plate, and the baffle plate is fixed on the crystallizer box body. Baffle holes are formed in the baffle plate, the baffle plate is obliquely arranged, and the lower end of the baffle plate is fixed with the crystallization plate. According to the technical scheme, the structure of the crystallization plate group is optimized, so that the heat exchange area is increased, the heat exchange effect is improved, the defects of long crystallization time, low purity and the like when the existing industrial purification equipment is used for purifying vinylene car
