METHOD FOR CONTROL OF AIRLIFT OPERATION

摘要

Method for control of operation of airlift relates directly to branch of development of underwater mineral beds. The invention makes it possible to remove gumming of separate elements of hydrotransport system included to set of complex for development of underwater mineral beds. It is provided by fact that preliminarily one sets condition of ratio for working value of concentration of solid particles in flow of multi-component mix in the upper part of column of lift pipeline of airlift to working concentration of solid particles in flow of hydro-mix of supply pipeline of airlift that comes to mixer of lift pipeline of airlift. Gradually one increases value of flow rate of supply of secondary milled rock mass to water flow of supply pipeline 14 of airlift and value of flow rate of supply of compressed air to mixer 25 of lift pipeline 15 of airlift. By means of consistence meters 43, 44 one determines actual current value of working value of concentration of solid particles in flow of multi-component mix in the upper part of the set of lift pipeline of airlift 15 and real current value of working concentration of solid particles in flow of hydro-mix of supply pipeline 14 of airlift that comes to mixer 25 of lift pipeline of airlift. One controls in process of functioning of airlift realisation of given condition and achieves maximal value of flow rate of supply of secondary milled rock mass to water flow of supply pipeline 14 of airlift at provision of stable realisation in time of given condition.
