Small seawater desalination device for marine survival

Abstract

The invention discloses a small sea water desalination device for marine survival. The small sea water desalination device comprises a base, wherein the bottom of the base is fixedly communicated with four air bags, the top of the base is fixedly communicated with four first through pipes, and one ends, far away from the base, of the four first through pipes are fixedly welded with through plates. According to the small sea water desalination device for marine survival, an air bag floating structure is additionally arranged, so that the problems that the size of the device is large, fishing cannot be performed once the device falls into the sea, fresh water resources may be directly lost, and fresh water materials on a ship may be insufficient are solved; a load bearing structure is additionally arranged, the problems that when special weather such as big waves is encountered on the sea surface, the device possibly shakes seriously, and the device possibly turns on one side are solved; and a fresh water collection and protection structure is additionally arranged, so that the problems that when an existing purification structure discharges fresh water, collection is difficult, the production efficiency of fresh water resources cannot be guaranteed, and the service life of the device is prolonged are solved.

Description

technical field [0001] The invention relates to the technical field of seawater desalination, in particular to a small seawater desalination device for survival at sea. Background technique [0002] Seawater desalination is the use of seawater desalination to produce fresh water. It is an open-source incremental technology to realize the utilization of water resources. It can increase the total amount of fresh water and is not affected by time, space and climate. It can ensure a stable water supply for coastal residents and industrial boilers. Desalination of seawater is the process of obtaining fresh water. Currently used seawater desalination methods include seawater freezing method, electrodialysis method, distillation method, reverse osmosis method, and ammonium carbonate ion exchange method. At present, the application of reverse osmosis membrane method and distillation method is the mainstream in the market. [0003] Some desalination units currently on the market: ...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to provide a small-scale seawater desalination device for survival at sea, to solve the above-mentioned background technology because the device itself is heavy, once it falls into the sea Fishing cannot be carried out, which may lead to a direct loss of fresh water resources, which may lead to insufficient fresh water supplies on board, causing life threats. When encountering special weather such as big waves on the sea surface, it may cause serious shaking of the device and affect the efficiency of fresh water purification. It may also cause the device to overturn and lose fresh water resources. When the existing purification structure discharges fresh water, it is more difficult to collect, and a large amount of water may be lost as a result, so that the production efficiency of fresh water resources cannot be guaranteed, which may affect the performance of the device. work efficiency problem
