The skid-mounted miniaturized air blowing alkaline bromine extraction test device mainly targets bromine-containing raw material liquids of different grades and carries out technical services for bromine extraction process research and development and optimization verification for industrialization. The device includes chlorine gas supply unit, blowing unit, evaporation unit and instrument automatic control system, which can be flexibly configured according to the owner's requirements. It has the following advantages: 1) Mature process and wide application range. It adopts the reliable "air blowing-urea reduction" process to prepare sodium bromide completion liquid, suitable for medium and low concentration bromine resources such as 0.05~0.5g/L. 2) Miniaturized skid-mounted equipment with strong applicability. Modular design is adopted; the chlorine gas generation unit and air blowing tower group unit are independently skid-mounted. It supports remote transportation and rapid deployment. The number of skids can be adjusted according to the water quality and treatment volume at different extraction points to ensure extraction effect. 3) High safety and environmental protection. Chlorine gas is prepared in situ and used immediately without storage; the product is sodium bromide, which is easy to transport and store, and is not a hazardous chemical.
Application scope: Extraction of low-grade bromine resources that are relatively dispersed with large differences in water quality and bromine content, such as small-scale seawater, concentrated seawater, oil and gas field produced water, and mineral-associated bromine.
