Method for recycling low-hafnium zirconium oxide fine powder
The invention discloses a method for recycling low-hafnium zirconium oxide fine powder, which comprises the following steps: mixing low-hafnium zirconium oxide fine powder, pure water and an organic additive carboxymethyl cellulose, and grinding to obtain low-hafnium zirconium oxide slurry; granulating to obtain low-hafnium zirconium oxide granulated powder; performing degumming treatment in a drying oven to obtain low-hafnium zirconium oxide degummed powder; and screening the low-hafnium zirconium oxide degummed powder by using a spin vibration screen to obtain screened particles, namely a low-hafnium zirconium oxide product. Any other useless impurities are not doped in the granulation process, and granules formed by granulation are high in strength and cannot be refined under boiling chlorination conditions; the low-hafnium zirconium oxide powder obtained through granulation is more uniform in particle and good in subsequent chlorination reaction activity, the yield of a downstream chlorination process is further improved, and resources are saved; meanwhile, the granularity of the product can be adjusted according to the characteristics of a fluidizing chlorination reaction furnace, and the fluidizing chlorination requirement is better met; and the utilization rate of the low-hafnium zirconium oxide fine powder can reach 100%.
本发明公开了一种低铪氧化锆细粉料回收应用的方法，取低铪氧化锆细粉、纯水和有机添加剂羧甲基纤维素混合后进行研磨，得到低铪氧化锆浆料；造粒得到低铪氧化锆造粒粉；在烘箱中进行脱胶处理，得到低铪氧化锆脱胶粉；使用旋振筛对低铪氧化锆脱胶粉进行筛分，得到筛分颗粒为低铪氧化锆产品。在造粒过程中未掺入任何其他的无用杂质，造粒形成的颗粒强度大，在沸腾氯化条件下不会细化；造粒得到的低铪氧化锆粉体的颗粒更均匀，在后续的氯化反应活性好，下游氯化工序的收率进将一步提高，节约了资源；同时产品粒度可根据沸腾氯化反应炉的特性调整，更好地适合沸腾氯化要求；低铪氧化锆细粉料利用率可达100%。
