Description

technical field [0001] The invention relates to a seawater desalination device, in particular to a ship-mounted wave energy seawater desalination device which utilizes ocean wave energy to desalinate seawater. Background technique [0002] Wave energy has the advantages of large reserves, wide distribution, no pollution, and renewable, and is becoming a new hot spot in the utilization of renewable energy. At present, the use of wave energy is mainly for power generation. According to the non-patent literature "Design of Miniature Water Wave Power Generation Device [J]" (author Shen Xin, Wireless Internet Technology, 2015, 03: 73-75.) and "Array Wave Hydrodynamic analysis of energy generating devices[J]” (Authors He Guangyu, Yang Shaohui, He Hongzhou, Wang Fengyin, Journal of Hydroelectric Power, 2015, 02: 118-124) There have been extensive research and new progress in wave energy generation, but due to The shortcomings of low wave energy density and poor stability lead to l...

Problems solved by technology

However, this technical device has a large volume, complex system structure, difficult installation and maintenance, and is not suitable for use as a ship-mounted fresh water purification device.

[0007] In addition, most of the existing wave energy seawater desalination devices are large-scale structures used on the coast. The devices are huge and are not suitable for providing fresh water on ocean-going cargo ships. Most of the devices need to use electric energy as power, which cannot meet the requirements of low energy consumption. requirements

Moreover, almost all existing patents are only one-way processing, there is no detection and feedback device to detect whether the concentration of desalinated seawater reaches the standard, and there is a lack of real-time monitoring and feedback of water quality
