摘要
采用清水和空气作为介质,利用实验室条件下冷态模拟气提系统。试验结果表明在通气量一定时,随着回水流量的增大,水的压差逐渐降低。当回流水量相同时,压差随着通气量的增大而升高。气含率随着表观气速的增大而增大。
Under laboratory condition, the airlift system was simulated by using the air and the water as media. The results showed that with the amount of ventilation unchanged, the pressure differenee was smaller as the return flow was greater. With the return flow unchanged, the greater the pressure difference was greater as the amount of ventilation was greater. As the superficial gas velocity was greater, the gas -ratio was greater.
