摘　　要：地浸采铀矿山洗井工艺是提高钻孔水量的重要手段,但洗井废水中的大量泥砂等杂质导致袋式过滤器及吸附塔塔压升高,间接影响了生产进度。运用离心力作用原理,研制了一种地浸采铀矿山洗井废水除砂装置,并在某地浸采铀矿山进行了应用研究。结果表明,其可降低袋式过滤器压力及吸附塔塔压,减少过滤袋更换频次,提升吸附水量,增加产能。该洗井废水除砂装置在地浸采铀矿山钻孔洗井工艺中有一定的推广价值。The well washing process of in-situ leaching uranium mine is an important means to increase the amount of drilling water.However,a large amount of impurities such as sediment in the well washing wastewater cause the bag filter and adsorption tower pressure to rise,which indirectly affects the production progress.Based on the principle of centrifugal force,a sand removal device for well washing wastewater was developed and applied in a certain in-situ leaching uranium mine.The results show that it can reduce the pressure of bag filter and adsorption tower,reduce the frequency of filter bag replacement,increase the adsorption water and increase production capacity.The sand removal device of the well washing wastewater has a certain popularization value in the drilling and well washing technology of in-situ leaching uranium mine.
