Description

Technical Field

[0001] The utility model relates to the technical field of osmotic membranes, and particularly relates to a high-salinity water osmotic membrane desalination device. Background Art

[0002] An osmotic membrane is a membrane that separates two or more groups of solutes under the push of external force or osmotic pressure through the osmotic membrane technology with selective permeability, and it is widely used in various fields.

[0003] For example, in the process of high-salinity water desalination, the osmotic membrane can play an ion selection role. In the process of high-salinity water desalination, the osmotic membrane only allows hydroxide ions, protons and water molecules to pass through, while blocking all other ions.

[0004] Moreover, the way of setting the osmotic membrane is particularly important. The efficiency of the single-stage osmotic system is usually lower than that of the multi-stage system, because as water molecules pass through the osmotic membrane, the salt concentration on the absorption liquid side gradually decreases, but the single-stage system cannot make full use of this concentration gradient to improve the water molecule permeability. Coupled with the limited contact time between the salt solution and the single-stage osmotic membrane, therefore, for high-salinity water desalination applications that require very high efficiency, the single-stage system may not meet the requirements. For the multi-stage osmotic system, whether each osmotic membrane can be fully utilized will affect the efficiency of salt water desalination. Content of the Utility Model
