Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of metal molybdenum extraction, especially to molybdenum concentrate tail gas absorption liquid is with metal molybdenum extraction equipment. BACKGROUND

[0002] In the processing of molybdenum concentrate, tail gas containing molybdenum compounds is usually generated. If these tail gases are not treated, not only will it cause environmental pollution, but also will lead to the loss of valuable molybdenum resources. In order to effectively recover the molybdenum elements in these tail gases, the industry has adopted tail gas absorption liquid technology, that is, through the absorption liquid to capture and dissolve the molybdenum compounds in the tail gas. Subsequently, using a specially designed metal molybdenum extraction equipment, the molybdenum compounds in the absorption liquid are extracted and separated. The equipment converts the molybdenum compounds into metal molybdenum through a series of processing processes such as precipitation, filtration, reduction, etc. Finally, the purified metal molybdenum can be further processed into molybdenum products for various industrial applications.

[0003] The prior art has a significant deficiency in the extraction of metal molybdenum, that is, the medicine and the absorption liquid cannot be fully contacted and mixed during the processing, resulting in a slow precipitation process of molybdenum compounds. This deficiency mainly reflects in the uneven mixing between the medicine (such as precipitant) and the absorption liquid in the reaction system, which makes the chemical reaction inefficient and slows down the generation and precipitation of molybdenum compounds. Due to incomplete reaction or low reaction rate, molybdenum compounds cannot be quickly precipitated from the solution, resulting in a decrease in the efficiency of the entire extraction process. In addition, slow precipitation will cause molybdenum compounds to stay in the solution for a long time, increasing the uncertainty of the reaction and requiring longer processing time or higher drug dosage to achieve the desired precipitation effect. This not only wastes drug resources, but also increases production costs, affecting the economy and operability of the extraction process. UTILITY MODEL CONTENT
