The present invention relates to a salinity gradient power generation apparatus circulating salt water. The salinity gradient power generation apparatus circulating salt water comprises: a fresh water tank to store fresh water; a salt water tank to store salt water, come in contact with the fresh water tank around an osmotic membrane disposed, and change the stored salt water into brackish water by an osmotic pressure created by the fresh water passing through the osmotic membrane and infiltrating thereinto to spray the brackish water; a reverse osmotic unit to pass the sprayed brackish water through a reverse osmotic membrane to circulate fresh water passing through the reverse osmotic membrane to the fresh water tank and circulate salt water which does not pass through the reverse osmotic membrane to the salt water tank; and a power generation unit wherein the reverse osmotic unit operates a turbine with the fresh water passing through the reverse osmotic membrane to generate power. According to the present invention, supply of salt water can be reduced, and environmental pollution can be prevented by preventing production of salt water mixed with fresh water. Power generation efficiency can be improved when a certain amount of salt water is used to generate power. A pressure created by passing through the osmotic membrane is transferred in a vertical direction to reduce constraints of an installation place of the power generation apparatus. |
