Description
Technical Field
The invention belongs to the field of metallurgical equipment, and particularly relates to a multi-stage material reaction distillation separation device which is particularly suitable for distillation separation of a reaction product in which three phases of liquid, gas and solid exist simultaneously or two phases of solid and liquid exist.
Background
The material reaction and distillation are reduction smelting methods for physical and chemical reactions between substances and volatilization and condensation of substances (metals) in a metallurgical device in sequence. The process includes several steps of reduction of metal oxide and volatilization and condensation of the reduced metal. The reduction distillation is a unique metallurgical method, and is based on the premise that the reduced metal can be volatilized in a large amount at high temperature. Solid or liquid metals have a certain vapor pressure at a certain temperature, and the vapor pressure of the metal increases with increasing temperature. The metal vapor is obtained by reducing the metal oxide to a metal state at a high temperature. The metal vapor is volatilized from the metallurgical reactor, separated from high boiling point impurities in the charge such as gangue, and condensed to obtain the metal. The reduced metal from such metallurgical processes is volatilized in a gaseous state, so that there is generally no need to produce molten slag, and the resulting solid residue is discharged from the retort.
However, gases such as carbon monoxide or carbon dioxide are generated in the reduction reaction process, and when the main product is gaseous, the gases are difficult to separate after being mixed with the gases such as carbon monoxide or carbon dioxide, and the gases cannot be prepared by adopting the conventional vacuum distillation equipment. For example, the chinese invention patent CN201711278762.8 is a small-sized reduction distillation apparatus, which is mainly used for laboratory research or preparation of small-lot volatile metals and oxides, but the reaction chamber of the distillation apparatus is communicated with the distillation chamber, and in the reaction process, the product can be separated and purified by controlling the temperature, but in reality, due to too high temperature or uneven heating, the impurities with lower melting point and similar melting point are volatilized to introduce the impurities, and the difficulty of substance purification is increased; meanwhile, when the reaction product comprises a solid phase and a liquid phase or a solid phase, a gas phase and a liquid phase, the device also increases the difficulty of material purification.
