Zusammenfassung: | The utility model relates to a cooling crystallizer for difenoconazole production, relates to the technical field of crystallizers, and aims to solve the problems of non-uniform supersaturation degree distribution of materials in a crystallizing tank, low crystal generation rate and low crystal quality caused by low cooling rate of the materials in the center of the crystallizing tank in the cooling crystallization process of bromides of brominated phenyl ether. The crystallization device comprises a crystallization tank and a jacket arranged on the outer wall of the crystallization tank in a sleeving mode, an interlayer is formed between the jacket and the crystallization tank, a circulation pipeline allowing a refrigerant to circulate is arranged in the interlayer, and a stirring device used for stirring materials is arranged in the crystallization tank. A cooling pipe is arranged in the crystallizing tank, the cooling pipe penetrates through the central part of the crystallizing tank, the two ends of the c |
