Description

technical field [0001] The invention relates to the field of microwave equipment, in particular to a multifunctional microwave heating wet process pressure swing metallurgy reaction device. Background technique [0002] Microwave heating is the process of using the energy characteristics of microwaves to heat objects. The reaction of materials to microwaves can be divided into three situations: penetrating microwaves, reflecting microwaves, and absorbing microwaves. Different from traditional heating methods, microwave heating induces dipole molecules to perform high-frequency reciprocating motion and rotation, resulting in generation of dipole molecules. "Frictional heat" increases the temperature of the heated material without any heat conduction process. Therefore, microwave heating technology is widely used in people's daily life and industrial production. However, microwave heating also has limitations. When microwave heating is used, the temperature of the material ri...

AI Technical Summary

Problems solved by technology

However, microwave heating also has limitations. When microwave heating is used, the temperature of the material rises rapidly due to microwave heating. When the rated temperature is reached, the microwave will stop working due to the lack of an effective cooling mechanism. Therefore, there is a reaction process in these existing microwave equipment. The problem of discontinuous microwave radiation makes it impossible to effectively judge the influence of microwave radiation on the hydrometallurgical reaction process, and the existing equipment has problems such as low visualization, uneven stirring of ore pulp, and difficulty in feeding and discharging materials. Therefore, the existing technology still needs to be solved. for improvement and development
