TL;DR: Wang et al. as mentioned in this paper proposed a method and device for washing historical relics from water with circulation type micro-nano bubbly water through a power pump, which comprises the steps that air and water are pressurized and mixed through an air liquid mixing pump, so that an air-water mixture is obtained; and then, the airwater mixture generates the micro-nanano bubble generator so that the historical items from water can be washed.
