METHOD FOR START AND TERMINATION OF SEA AIRLIFT AND SYSTEM FOR ITS REALIZATION

摘要

Group of inventions relates to start and termination of sea airlift. System has lift and supply pipes between which mixer is installed, to that one supercharge pipeline from compressor is connected Compressed air can as well be supplied to the upper part of lift pipe through respective slide and back valve. Pressure of air is controlled with manometer. At that the upper part is surrounded with air separator to which suction pipeline of compressor is connected. At the outlet of the lift pipe there is gasket to which gate is fit. Supply pipe has rotary tap and indicator of liquid flow rate. For start of sea airlift one sets value of supply of sea water to lift pipe. One closes the lift pipe with gate and supplies compressed air to its upper part with pressing out water from it. One increases air pressure to value equal to difference of pressure at depth of mixer and maximal air pressure from compressor. Due to fact that pressure of water column in lift pipe is kept smaller than pressure of compressor it becomes possible to immerse mixer to depth exceeding pressure of compressor. One opens the gate and supplies compressed air to mixer. After that one opens rotary tap and provides controlled inflow of water through supply pipe. When water-air mix completely fills the lift pipe, the tap is opened completely. For termination of airlift one closes the gate of lift pipe and supplies compressed air to its upper part. When pressure reaches needed value compressor is terminated, rotary tap is closed and one opens the gate. The inventions promote increase of deepening mixer of lift pipe to pool of sea water and increase of productivity of airlift lift.
