ENVIRONMENTAL SEPARATION METHOD IN AIRLIFTING OF SUBMERSIBLE DEPOSITS OF MINERALS AND ITS IMPLEMENTATION SYSTEM Russian patent published in 2008 - IPC E21C50/00 E21C45/00 F04F1/20 

FIELD: machine building.

SUBSTANCE: environmental separation method in airlifting of submersible deposits of minerals and its implementation system which comprises lifted pipe, replenishment camera with a branch, feeding pipe, pump with force piping, air separator assembled on the lifted pipe, lifted pipe mixer connected to the force piping of the pump, compressor with a corresponding force piping, water separator assembled in an intermediate cross section of the pump force piping - separate accumulator, connected to a separate accumulator, and branch outgoing to environment, additional mixer connected to the pump force piping and to the compressor force piping, and fluid consumption sensor. Additional accumulator is installed in the intermediate cross section of the feeding pipe, and suction and force pipelines of an additional pump are tied to an additional accumulator. The separate accumulator comprises indicators of fluid level, suction pipeline of the additional pump is equipped with a tip, located in the additional accumulator. The force pipeline of the additional pump comprises pivotal position distributing valve, and blade wheel is installed in the additional accumulator. At that the force piping of the pump and the branch, connected to the separate accumulator, are equipped with corresponding controlled valves. The suction pipeline of the compressor is equipped with a filter and connected to an air separator, while a rotation speed sensor - a tachometer -is connected to the blade wheel.

EFFECT: improvement of environmental separation method in airlifting of submersible deposits of minerals; improvement of the ocean ecosystem.
