Outline
Usually, uranium mines discharge the waste water generated during the adsorption process into an evaporation pond, and eliminate radioactive waste water by natural evaporation.. The active acceleration technology for the evaporation capacity of domestic evaporation ponds, such as atomization devices, heating devices, wind blowing devices, etc., mostly has high energy consumption losses, high operating costs, and is difficult to put into large-scale use. Passive acceleration devices generally have limited improvement in evaporation capacity. A new type of evaporation tower with a frame structure and multiple horizontal evaporation surfaces was proposed. The evaporation towers are uniformly arranged in a matrix form in the evaporation pool, and each tower is connected in series by a wastewater pipeline fixed at the top of the tower to form a collaborative three-dimensional evaporation surface structure, greatly improving the utilization level of evaporation space and generating a multiplier effect on the evaporation capacity of the original evaporation pool. By conducting small-scale simulation experiments, the empirical calculation formula for the evaporation capacity of the evaporation tower matrix system can be used to achieve refined and quantitative design of the three-dimensional evaporation system. This method has the advantages of environmental protection, high efficiency, and no energy consumption, and is suitable for dry and low wind areas. It can effectively save land resources and engineering investment.
