Abstract
This utility model belongs to the field of chemical equipment technology and specifically discloses a falling film crystallizer capable of countercurrent heat transfer, which includes a cylinder, a cold and hot medium distributor, a crystallization tube fixing plate, a material distributor, a crystallization tube support plate, a crystallization tube, a cold and hot medium tube, a cold and hot medium inlet, a cold and hot medium outlet, a material inlet, and a material outlet.
The crystallization tube is sleeved on the cold and hot medium tube, and the upper end of the crystallization tube is provided with an opening, while the lower end is closed, The upper and lower ends of the refrigerant and heating medium pipes are both equipped with openings, the inlet of the refrigerant and heating medium is connected to the refrigerant and heating medium pipe, and the outlet of the refrigerant and heating medium is connected to the crystallization pipe. In this crystallizer, the material flows from top to bottom along the outer side of the crystallization tube, while the cooling and heating medium flows from bottom to top on the inner side of the crystallization tube. The material forms a countercurrent heat transfer with the cooling and heating medium, thereby effectively improving the heat transfer efficiency and crystallization efficiency.
