Seawater desalination ship

Abstract

The invention provides a seawater desalination ship, which comprises a ship body and a filtering system arranged on the ship body, wherein precipitation cabins in the ship body are used for precipitation treatment of seawater, and are symmetrically arranged at the two ends of the ship body, clear water cabins are used for primary filtration treatment of seawater and are symmetrically arranged on the two sides of the ship body, each clear water cabin is correspondingly communicated with one precipitation cabin, a filtering cabin is arranged in the middle of the ship body, two sets of filteringsystems are arranged in the filtering cabin, and a fresh water cabin is arranged below the filtering cabin to store fresh water obtained by multi-stage filtering treatment of the filtering system. According to the invention, the seawater desalination ship is short in construction period, low in construction cost and convenient to move, and can directly take water from seabed, wherein 20000-150000tons of fresh water treatment capacity every day can meet fresh water supply among coastal areas, coastal areas and island groups; and precipitation cabins and clear water cabins are symmetrically arranged, and two sets of filtering systems are respectively used for independently carrying out seawater filtering treatment operation, so that the loading and ballasting stability of the ship body canbe ensured, and the overall stability of the seawater desalination ship is ensured.

Description

technical field [0001] The invention relates to the technical fields of seawater desalination engineering and marine ships, in particular to a seawater desalination ship. Background technique [0002] At present, most of the countries with severe water shortages in the world are coastal countries. Seawater desalination can meet the demand for fresh water in some areas, but building a seawater desalination plant on land not only occupies a large area, but also takes a long construction period, and requires a lot of personnel and high cost. [0003] In addition, the freshwater sources of traditional island groups generally have the following three methods: 1. Continental supply of freshwater; 2. Conservation of rainwater to the greatest extent to store freshwater; 3. Desalination of seawater to obtain freshwater. Among them, the supply of fresh water from the mainland generally requires large ships to load a large amount of fresh water on the mainland, and then use personnel ...

Problems solved by technology

Among them, the supply of fresh water from the mainland generally requires large ships to load a large amount of fresh water on the mainland, and then use personnel to drive the ship to the islands that need fresh water. , but also a great waste of energy; purely relying on rainwater collection, only a limited amount of rainwater can be collected due to site conditions; building seawater desalination plants on each island not only wastes land use, but also has high construction costs
