| titleOfInvention | Deep-water airlift start-up methods |
| abstract | FIELD: machine building. n SUBSTANCE: method involves lifting of elements of underwater mineral deposits consisting of flow of transporting medium, transportation of hydraulic fluid in supply airlift pipeline, supply of compressed air to mixer of lifting pipeline, creation of multicomponent mixture after compressed air is supplied to hydraulic fluid mixture and transportation of multicomponent mixture flow in lifting airlift pipeline. At that, first, phantom cross section is chosen in the flow intended for transportation of elements of underwater mineral deposits, and for chosen phantom cross section there specified is the range of change of pressure value. Flows of water and air-and-water mixture are created in supply and lifting pipelines by supplying compressed air with the compressor to mixer of lifting pipeline Value of actual pressure is monitored in the chosen phantom cross section, as well as actual range of change of the monitored value is determined. Compliance of the certain actual range to the specified one is checked, and elements of underwater mineral deposits are supplied to water flow of supply airlift pipeline in case certain actual range belongs to the specified one. n EFFECT: increasing development efficiency of underwater mineral deposits at big marine depths due to shortening the total start-up time of airlift plant; avoiding the disturbance of transportation of solid material and gumming of pipelines during airlift start-up. n 2 cl, 3 dwg |
