An emergency semi-submersible seawater desalination device

Abstract

The invention relates to an emergency semi-submersible type sea water desalting device belonging to the field of sea water desalting devices. The emergency semi-submersible type sea water desalting device is characterized by comprising a solar evaporation mechanism, a cooling heat exchange mechanism and a thermoelectric power generation mechanism; the lower part of the solar evaporation mechanism is connected with the cooling heat exchange mechanism; the lower part of the cooling heat exchange mechanism is connected with the thermoelectric power generation mechanism; and the complete device floats on the sea surface during work, the solar evaporation mechanism is above horizontal plane of sea water, and the thermoelectric power generation mechanism is below the horizontal plane of sea water. Maritime available resources are completely utilized, energy-gathered heating and electric heating of the thermoelectric power generation mechanism are utilized for evaporating sea water, and evaporated water vapor is subjected to heat exchange with condensate water so that the water vapor is condensed. Thermoelectric power generation condition is formed through temperature difference formed by warm water of sea level and cold water at the periphery of the thermoelectric power generation mechanism, autonomous power generation is realized, the complete device can float on the sea surface to autonomously work, manual operation is not needed, power supply of an external device is not needed, and the difficulty of use of offshore application is completely solved.

Description

technical field [0001] The utility model relates to an emergency semi-submersible seawater desalination device, which belongs to the field of seawater desalination equipment. Background technique [0002] Water is the basic need to maintain life and health, but when in islands, desert areas or sea areas, although there are abundant seawater or brackish water resources, there is no fresh water for living or production. Especially for ships, small island explorers or small island survival personnel who have been drifting on the sea for a long time, they generally need to prepare enough fresh water to meet their life needs. Exhausted, in the process of waiting for rescue, fresh water has become an important thing that determines people's survival. At this time, there is an urgent need for a seawater desalination device that can be used in seawater for emergency use. [0003] At present, there are many seawater desalination methods, including evaporation, reverse osmosis, ion e...

AI Technical Summary

Problems solved by technology

[0003] At present, there are many seawater desalination methods, including evaporation, reverse osmosis, ion exchange and other main types, and the most widely used method in seawater desalination is evaporation, but most of them are extremely complicated and expensive

When shipwrecks and disasters occur, environmental constraints such as energy and volume of seawater desalination devices must also be considered. However, these current seawater desalination devices are large in scale and suitable for industrial use, but cannot adapt to emergencies at sea. When the accident occurs, they cannot work autonomously, so that the trapped personnel cannot get timely fresh water replenishment, which will affect the follow-up rescue.
