The invention discloses a molten-salt heat-exchange temperature-controlling device and a method of a reaction furnace body. The molten-salt heat-exchange temperature-controlling device comprises a reactor and a salt bath furnace capable of accommodating the reactor; the side wall of the salt bath furnace is provided with a cooling water jacket and heating resistance wires; a thermocouple used for monitoring molten salt temperature, a stirrer used for uniformizing molten salt temperature, and a flow diversion duct used for guiding molten salt flow direction in stirring processes are arranged in the salt bath furnace. The molten-salt heat-exchange temperature-controlling device and the method are capable of realizing reaction furnace body heating in an early reaction period, and maintaining a reaction furnace body ideal temperature in reaction processes effectively, reducing production cost, increasing reaction efficiency, and can be used for both continuous production and intermittent production; and production efficiency is increased. And in addition, the molten-salt heat-exchange temperature-controlling device is simple in structure, and high in temperature control accuracy, and is convenient for maintenance.
Description
technical field [0001] The invention relates to a molten salt heat exchange temperature control device and method for a furnace body of a reaction furnace. Background technique [0002] The principle of iodide purification is that in a vacuum-tight container, iodine vapor reacts with the purified metal at a lower temperature to generate volatile iodide, which dissociates into metal and iodine vapor on the mother wire at a higher temperature, and the metal It is deposited on the hot mother wire to make the mother wire grow up, and the iodine vapor returns to the raw material area to continue to react with the raw material metal, and the process is repeated. The key to realizing the process is to control two different temperature conditions in the reaction equipment, namely silk temperature and material temperature (ie furnace temperature). Among them, the wire temperature is obtained by directly applying voltage on the mother wire, and controlled by adjusting the electrode v...
