Title:
SEAWATER PREPROCESSING DEVICE FOR SEAWATER DESALINATION AND SEAWATER PREPROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2016/036010
Kind Code:
A1
Abstract:
The present invention relates to a seawater preprocessing device for seawater desalination and a seawater preprocessing method. The seawater preprocessing device for seawater desalination comprises: a preprocessing unit positioned offshore at a predetermined depth so as to remove impurities from seawater, thereby obtaining preprocessed water; a preprocessed water container positioned onshore so as to contain preprocessed water generated by the preprocessing unit; and a connection channel for connecting the preprocessing unit and the preprocessed water container such that the preprocessed water can be transferred. The preprocessing unit comprises: multiple water-collecting pipes supported by a support unit, multiple openings being formed on the side surface of each water-collecting pipe; multiple filtration filters configured in ring shapes and fitted to the outside of respective water-collecting pipes; a water-collecting tank for exchanging a fluid with each of the water-collecting pipes so as to contain preprocessed water that has passed through the filtration filers and the water-collecting pipes; and a water transfer pump for evacuating the interior of the water-collecting tank and transferring preprocessed water, which has been collected inside the water-collecting tank, through the connection channel. One end of each water-collecting pipe is closed, and the other end thereof exchanges a fluid with the water-collecting tank. By means of a difference in pressure between the interior and exterior of the filtration filters, seawater passes through the filtration filters in a reverse osmotic type, and is collected into the water-collecting tank via the water-collecting pipes. This configuration can provide a seawater preprocessing device for seawater desalination and a seawater preprocessing method, which can simplify the overall device configuration while consuming less energy in the preprocessing process for seawater desalination.
