Problems solved by technology

[0006] B. Seawater desalination plants built on land also use water pumps to circulate the normal temperature water in the cooling pool to liquefy fresh water. The "cold energy" of the liquefied fresh water depends on the circulating cooling of the sprayed air on the spot. The water source is "air-cooled", which is inefficient and needs to consume artificially provided "air-cooled" energy, for example: providing the power consumed by the fan to implement "air-cooled". Although this method is effective, it is different from the above-mentioned Compared with "A", the consumption of artificially provided energy will naturally be more

Embodiment Construction

[0020] The main parts (components) included in the seawater desalination plant (facilities or equipment or appliances) are: seawater evaporator 5 (composed of a sealed shell) and its heating facility 6 (heated by electric heating or fuel or coal-fired heating methods), And the water vapor liquefier 2 (consisting of a sealed shell) and its cooling facility 3 (water-cooled dense layout coil type), they are all arranged in a hull 1. Due to the high cost of fresh water produced by seawater desalination plants, general seawater desalination plants are mainly used for areas lacking fresh water (for example: offshore oil and gas mining bases, islands without fresh water, Arabian Peninsula and North African offshore desert areas or countries) Therefore, its scale is usually not designed very large (compared with general waterworks), so that the entire seawater desalination plant (for example: daily production of tens to hundreds of tons of fresh water ) is arranged on a reinforced con...

Abstract

A seawater desalination plant(ship) or its use are disclosed. It consists of marine evaporato5, heating apparatus6, aqueous vapor liquefier2 and cooling apparatus3. It can save resources and be used for marine gas-oil exploitation, island without fresh water and desert areas.

Description

Technical field: [0001] The invention relates to a technical application method for setting a seawater desalination plant on board. Background technique: [0002] Currently, the most commonly used seawater desalination method in seawater desalination plants (facilities or equipment or utensils) is the seawater heating distillation condensation method, or the seawater heating multiple distillation condensation method, and its disadvantages are: [0003] 1. The fresh water raw material produced by seawater desalination plants is seawater. However, general seawater desalination plants, especially large-scale seawater desalination plants, are built on land, which is superfluous: it wastes valuable land and is difficult to base on The water quality situation adjusts the geographical location of the water inlet for drawing raw seawater from the sea at any time. [0004] 2. The water vapor produced by heating seawater process distillation or multiple distillation, in the cooling a...
