Method and apparatus for osmotic power generation

摘要

An osmotic power generation system and method for generating osmotic power includes a membrane chamber having a semi-permeable membrane therein defining a first portion and a second portion therein. The system also includes a first pump communicating a first fluid to the first portion and a second pump communicating a second fluid to the second portion. The second fluid has higher total dissolved solids than the first fluid. A second portion energy recovery device is in fluid communication with the second portion. A power generator is in communication with the second portion energy recovery device generating electrical power in response to the second portion energy recovery device and the pressure in the second portion.

1. An osmotic power generation system comprising:
a membrane chamber having a semi-permeable membrane therein defining a first portion and a second portion therein; a first pump communicating a first fluid to the first portion of the membrane chamber, a second pump communicating a second fluid to the second portion of the membrane chamber, said second fluid having a higher total dissolved solids than the first fluid; a first portion energy recovery device in direct fluid communication with the first portion of the membrane chamber and rotates with the first pump and the second pump on a common shaft; an electrical second portion energy recovery device disposed on an rotating with the common shaft, said second portion energy recovery device is in direct fluid communication with the second portion of the membrane chamber; and an electrical power generator in rotational communication with the first portion energy recovery device and the second portion energy recovery device through the common shaft, said electrical power generator generating electrical power in response to rotation of the first portion energy recovery device from fluid pressure from the first portion of the membrane chamber and rotation of the second portion energy recovery device from fluid pressure from the second portion of the membrane chamber.
