    • PCT No. PCT/AU84/00097 Sec. 371 Date Jan. 28, 1985 Sec. 102(e) Date Jan. 28, 1985 PCT Filed Jun. 1, 1984 PCT Pub. No. WO84/04702 PCT Pub. Date Dec. 6, 1984.A cyclone separator (10) having an elongated tapered separating chamber (25) with tangential inlet pipes (26, 28) thereto, and overflow outlet pipe (34) at the larger diameter end of the separating chamber, for outflow of a less dense component of a liquid mixture to be separated, and an underflow outlet (23) at the smaller diameter end of the separating chamber, for outflow of the denser component of the liquid mixture to be separated. The overflow outlet pipe (34) has an orifice (77) which is variably obstructable by a valve member (80) movable lengthwise of the pipe (34), to vary the flow rate through the outlet pipe (34). The degree of contamination of the denser liquid component emerging from the underflow outlet (23) is monitored by a detector (118) which is connected to a control circuit (108) which controls a motor (110). Motor (110) is coupled to valve member 80 whereby to move the valve member towards and away from the orifice (77), whereby to decrease the flow through outlet pipe (34) when the contamination level drops and to increase flow when the contamination level rises. A further control circuit (140) coupled to detector (118) is effective to control valves (102, 104) whereby to recycle the denser liquid component through the separator in the event that the contamination level is determined to be above a predetermined level.
    • 旋风分离器(10)具有带切向入口管(26,28)的细长锥形分离室(25),在分离室较大直径端的溢流出口管(34),用于较低密度组分 的待分离的液体混合物,以及位于分离室的较小直径端处的底流出口(23),用于将待分离的液体混合物的致密组分流出。 溢流出口管(34)具有孔(77),孔(77)可由管(34)纵向移动的阀构件(80)可变地阻挡,以改变通过出口管(34)的流量。 通过连接到控制马达(110)的控制电路(108)的检测器(118)监测从底流出口(23)排出的更稠密的液体组分的污染程度。 马达(110)联接到阀构件(80),由此使阀构件朝向和远离孔口(77)移动,从而当污染物水平下降时减小通过出口管(34)的流量并且当污染物水平下降时增加流量 污染水平上升。 耦合到检测器(118)的另一控制电路(140)有效控制阀(102,104),由此在污染物水平被确定为高于预定水平的情况下再循环密度更大的液体组分通过分离器。
