Description

TECHNICAL FIELD

[0001] The utility model is applied to the octanol recovery field, especially relates to a kind of octanol recovery device in tantalum niobium mixed solution. BACKGROUND

[0002] In the processing of tantalum niobium mixed solution, octanol is often used as an extractant to extract tantalum and niobium from the mixed solution. However, after completing the extraction task, octanol often mixes with the tantalum niobium mixed solution to form waste liquid containing octanol. Since octanol is a valuable resource, if this waste liquid is directly discharged, not only will it cause resource waste, but also may pollute the environment.

[0003] Currently, for the treatment of tantalum niobium mixed solution containing octanol, traditional separation methods such as distillation, extraction, etc. are mainly used. However, these methods often have problems such as high energy consumption, low efficiency, complex operation, etc., which are difficult to meet the needs of modern industry for high efficiency, environmental protection and energy saving.

[0004] In addition, when treating tantalum niobium mixed solution containing octanol, traditional separation methods often have difficulty in completely separating octanol, resulting in a certain amount of octanol remaining in the waste liquid. This not only affects the effect of subsequent processing steps, but also may have adverse effects on product quality.

[0005] Therefore, based on the above problems, if a tantalum niobium mixed solution octanol recovery device can be designed, the recovery device has simple structure and low price, by placing the tantalum niobium mixed solution in a low temperature state, the separation effect is achieved, the recovery efficiency of octanol is improved, the energy consumption is reduced, and the maximum utilization of resources is realized. The above problems can be well solved. SUMMARY

Therefore, multistage clarifying device gives cooling device, a plurality of collection devices and oil separation device play the role of support and fixed, and the cooling device plays the role of cooling to tantalum niobium liquid, so that the tantalum niobium liquid keeps low temperature state, because the density of secondary octyl alcohol is lower and lower with the lower temperature, thereby better benefitting the separation of secondary octyl alcohol, and a plurality of collection devices play the role of recovery to secondary octyl alcohol, and multistage clarifying device also plays the role of transportation limiting to tantalum niobium mixed solution, and long and narrow makes most tantalum niobium liquid can be cooled down fast, keeps low temperature state, and oil separation device plays the role of secondary depth oil separation to tantalum niobium liquid.

[0014] As Figure 1 and Figure 2As shown in the embodiment, the utility model discloses cooling device 1, multistage clarifying device 2, a plurality of collection device 3 and oil separation device 4, cooling device 1 is arranged at the entrance of multistage clarifying device 2, oil separation device 4 is arranged at the outlet of multistage clarifying device 2, a plurality of collection device 3 is arranged at the top of multistage clarifying device 2, and tantalum niobium mixed solution is sequentially matched with cooling device 1 and multistage clarifying device 2, and the tantalum niobium mixed solution separates the tantalum niobium liquid and the secondary octyl alcohol in multistage clarifying device 2, and the secondary octyl alcohol is discharged to the device outside through a plurality of collection devices 3. Therefore, multistage clarifying device 2 plays the role of supporting and fixing cooling device 1, a plurality of collection devices 3 and oil separation device 4, cooling device 1 plays the role of cooling the tantalum niobium liquid, so that the tantalum niobium liquid keeps low temperature, because the lower the temperature is, the lower the density of secondary octyl alcohol is, so that the separation of secondary octyl alcohol is better, a plurality of collection devices 3 play the role of recycling the secondary octyl alcohol, and multistage clarifying device 2 also plays the role of transporting and limiting the tantalum niobium mixed solution, so that most of the tantalum niobium liquid can be rapidly cooled and kept in low temperature, and oil separation device 4 plays the role of secondary deep oil separation for the tantalum niobium liquid.

[0015] As Figure 1 As shown in the embodiment, multistage clarifying device 2 includes at least three separation zones 20, and a plurality of separation zones 20 are connected head to tail.

Therefore, the front separation zone 20 of multistage clarifying device 2 is all larger than the separation zone 20 of the middle part because when liquid flows from a place with large flow path into a place with small flow path, the liquid will flow slowly, further increasing the temperature of the tantalum niobium mixed solution, and the rear separation zone 20 of multistage clarifying device 2 is all larger than the separation zone 20 of the middle part because when liquid flows from a place with small flow path into a place with large flow path, the liquid space suddenly increases, further playing the role of accelerating the liquid.
