In figure 1, 2, 3, 4, 5 and 6 shows a diagram of a system for implementing the method electrification technology is underwater mining.

System for electrification technologies underwater mining contains the lifting tube 1, the camera feed 2 to the pipe 3, the inlet pipe 4, the pump 5 with 6 suction and discharge 7 piping that is installed on the lifting tube 1 air-purge drum 8, is in communication with the discharge pipe 7, the mixer 9 of the riser pipe 1, the compressor 10 with the corresponding suction 11 and discharge 12 pipelines installed in the intermediate cross section of the discharge pipe 7, the separator is a separate battery 13 connected to a separate battery 13 and communicated with the environment pipe 14 connected to the discharge pipe 7 and is in communication with the discharge pipe 12 additional mixer 15, the sensor determining the liquid flow 16, and the power station 17, which convert the energy of ocean currents into electrical energy communicated through the transmission line 18 and a power Converter 19 with the respective drive motors 20 and 21 of the compressor 10 and the pump 5, the lifting tube 1 contains a number of additional batteries 22, 23, the suction pipe 11 includes a filter 24 and is communicated with the air-purge drum 8, the deflectors 25 and 26 are installed in the respective secondary batteries 22 and 23, signalsto the s top 27 and bottom 28 of the fluid levels are in a separate battery 13, the discharge pipe 7 and is connected with a separate battery 13 pipe 14 is equipped with the corresponding controlled by valves 29 and 30, the power station 17 is located on the submersible platform 31, and the discharge pipes 12 and 7 contain check valves 32 and 33, respectively. The system further comprises a control unit 34.

The method of using the system for electrification technologies underwater mining is implemented as follows.

Pre-set the flow rate of the slurry supply pipe 4 and is immersed in the ocean located on the submersible platform 31 power station 17, which begins to convert the energy of ocean currents into electrical energy. Before starting the system for the electrification technologies underwater mining operated valves 29 and 30 are completely closed.

The control unit 34 starts the drive motor 21 of the pump 5 and opens the controlled valve 30. After a certain operating time of the pump 5, the appropriate output of the pump 5 on its performance, the control unit 34 starts the drive motor 20 of the compressor 10. Compressed by the compressor 10, the air enters through equipped with a check valve 32 injection pipe 12 and fill in the compulsory mixer 15 in the discharge line 7. Upon admission of compressed air into the fluid flow in the discharge pipe 7, there is formed a flow of water-air mixture, which is supplied in a separate battery 13. In a separate battery 13 compressed air is located in its upper part, and the water in the pipe 14 through the open controlled valve 30 is discharged in the environment.

After lowering the water level in a separate battery 13 below alarm upper liquid level 27, the control unit 34 is partially opens the controlled valve 29. The level of immersion of the individual battery 13 is lower than the level of immersion mixer 9 of the riser pipe 1 (see figure 4), and after partial opening of the controlled valve 29 is accumulated in a separate battery 13 compressed air under the force of Archimedes through the discharge pipe 7 and the mixer 9 is supplied into the flow of the slurry of the riser pipe 1.

During lifting of a multicomponent mixture in the lifting tube 1 when the circular structure of the flow of compressed air is concentrated in the center of the stream. Installed in the secondary battery 22 and 23 corresponding deflectors 25 and 26 provide movement of the compressed air from the center of the flow of multicomponent mixtures on its periphery. This results in a reduction in the rate of slip of the gaseous component mnogokomponentye the th mixture in the upper part of the riser pipe 1 due to the mixing of the flow components of a multicomponent mixture of the riser pipe 1 and, therefore, improving the efficiency of transportation. The output from the multicomponent composition of the mixture in the air-purge drum 8, the air re-enters through inlet pipe 11 through the filter 24 to the compressor 10.

After distribution of the flow of multicomponent mixtures over the entire length of the riser pipe 1, the control unit 34 by using a sensor determining the liquid flow 16 controls the flow rate of the slurry supply pipe 4, compares the monitored value with the set and achieve their compliance by controlling the magnitude of the dip in the ocean located on the submersible platform 31 of the power station 17, which converts the energy of ocean currents into electrical energy. After reaching the set value of the flow rate of the slurry in the inlet pipe 4 level of immersion submersible platform 31 stabilize. The operation of the collection and preparation of particles for the transportation are separate issues and in this application will not be considered.

In the process of electrification technologies underwater mining of mineral deposits while reducing the level of water in a separate battery 13 below alarm lower liquid level 28, the control unit 34 increases the amount of opening of the controlled valve 29 and reduces the value of open is I controlled valve 30. When the water in a separate battery 13 alarm upper liquid level 27, the control unit 34 reduces the amount of opening of the controlled valve 29 and increases the amount of opening of the controlled valve 30.

Directly before stopping system for electrification technologies underwater mining control unit 34 executes the stop of the drive motors 20 and 21 of the compressor 10 and the pump 5, respectively, with subsequent complete closure of the controlled valves 29 and 30. When this check valve 33 prevents the flow of compressed air from the discharge pipe 7 into the pump 5.

Thus, the use of the claimed invention will improve lift efficiency and green technology underwater mining of mineral deposits through the use of additional natural energy sources.

Rigid pipes are connected with each other so that the pipes may perform mutual rotation in areas of pipe axes crossing.

EFFECT: extended functional capabilities of sludge line and simplified flexible hose floatability control in rigid composite pipes.
