摘要:
为提升液液水力旋流器对小粒径油滴含油废水分离效果,采用先注气后旋流的处理方法。空气以气泡形式进入混合物中,对油水混合液流进行气浮旋流,在油相和水相之间形成气体隔层,减小油水混合的程度。同时,注气能够减小混合物密度,增加相对密度差,从而利于分离。以采出液样品为试验材料,改变注入混合液的空气量和进口雷诺数,研究不同工况下旋流器的分离效果。试验研究表明:当气液比为1.5%,进口雷诺数在14 000～17 000范围时,旋流器溢流口压降比略有下降,溢流欧拉数明显下降,流体动能量损失减少,分离效率从77%(未注气)提升到86%(气液比为1.5%)。
Abstract:
In order to improve the separation efficiency of dispersed oil from water by hydrocyclones, a new process of utilizing air has been developed to enhance the separation efficiency. The air bubbles were enhanced into the mixture and enhance the impact of the cyclone according to forming a spacer between oil and water, which reduced the strength of oil-water incorporation. Meanwhile, the gas can reduce the density of mixture and increase density difference, thereby facilitating separation. Taking the produced fluid samples as materials that are needed, changing the amount of air flow and the Reynolds number of mixture the cyclone separation data in different conditions were obtained. Experimental studies have shown, when the gas-liquid ratio is 1.5%, the Reynolds number ranging at the 14 000—17 000, cyclone pressure ratio has decreased a little and Euler number has a good change which means the loss of kinetic energy reduced, the oil removal efficiency increased from 77%(air-liquid ratio 0%)to 86%(air-liquid ratio 1.5%).
