Description

Technical Field

[0001] The utility model relates to the technical field of fluorine removal from tantalum-niobium smelting wastewater, in particular to a production device for deep fluorine removal from tantalum-niobium smelting wastewater. Background Art

[0002] With the continuous development of society, people's environmental pollution is becoming more and more serious. In the process of tantalum and niobium smelting, the main steps of tantalum smelting are to decompose the concentrate, purify and separate tantalum and niobium to produce pure compounds of tantalum and niobium, and finally produce metals. In this process, a large amount of organic and heavy metal wastewater will be generated, which will also contain fluorine waste gas. If it is not effectively treated and directly discharged, it will cause serious pollution to the environment. At present, there are various production devices suitable for deep defluorination of tantalum and niobium smelting wastewater on the market, but there are still some shortcomings;

[0003] For example, in actual use, a general production device for deep defluorination of tantalum-niobium smelting wastewater will only use a filter to filter the tantalum-niobium smelting wastewater, which will result in incomplete filtration. At the same time, the heavy metals in the tantalum-niobium smelting wastewater cannot be effectively separated, and the fluorine waste gas cannot be completely absorbed. In addition, after the defluorination device is used, there will be impurities left over from the wastewater filtration inside, which will affect the service life of the device if not treated. Therefore, we propose a production device for deep defluorination of tantalum-niobium smelting wastewater to solve the above problems. Utility Model Content
