Double cone for generation of a pressure difference |
摘要 |
The lifetime of a double-cone device (21) for creating a pressure difference in a streaming fluid can be greatly increased by moving the inlet gap (5) into the exit cone (4). This results in a short so-called diffuser (22) being obtained between the gap (5) and the orifice (19), where entry cone (3) and exit cone (4) are connected. The increased lifetime permits the double-cone device to cope with much higher flow rates. Thus higher system pressures are created which enhance the use of the double-cone for such applications as the desalination of sea water by reverse osmosis.The important application of the seperation of oil from water using a separating device such as a cyclone (57) working under elevated pressure is now feasible.The increased power of the double-cone permits one to profit more fully from the new concept of reduction of the concentration of the feed supplied to the double-cone device (21).
