Problems solved by technology

[0005] The purpose of the present invention is to provide a pervaporation seawater desalination system that efficiently utilizes engine waste heat, through the design of a pervaporation seawater desalination system that efficiently utilizes engine waste heat to solve the problems in the prior art when ships operate in seawater for a long time. The power is low, the heat of the cooling water output by the engine cannot heat the seawater to achieve seawater desalination, and additional energy needs to be introduced to heat the seawater, which does not really achieve the purpose of energy saving and emission reduction, and is not conducive to the long-term operation of ships in seawater. Technical problems

Abstract

The invention relates to the technical field of seawater desalination and particularly relates to a pervaporation type seawater desalination system capable of efficiently utilizing waste heat of an engine. The seawater desalination system comprises a seawater pumping device, a first seawater preheating device, a second seawater preheating device, a seawater heating device, a pervaporation type desalination module device and a fresh water collection device which are connected in sequence. According to the pervaporation type seawater desalination system capable provided by the invention, the seawater desalination can be realized by virtue of the waste heat of the engine both in the high-power working process and low-power working process of the engine, and the system is connected with the engine, so that the working efficiency of the engine can be improved, and the system can be applied to ships which has a long-term endurance requirement or needs to stay to work on seawater for a long time; and the system is high in seawater desalination efficiency, good in fresh water quality, energy-saving and environment-friendly and is wide in application prospects.

Description

technical field [0001] The present invention relates to the technical field of seawater desalination, and in particular relates to a pervaporation seawater desalination system that efficiently utilizes engine waste heat. Background technique [0002] Ships have a large demand for fresh water for long-term voyages and long-term stays at sea. The fresh water reserves of ships are limited, and long-term storage of water is likely to cause bacterial growth, which brings many unfavorable factors. Therefore, people install seawater desalination systems on ships. To realize the desalination of seawater, so that people can work in seawater for a long time, but the seawater desalination system needs a lot of heat to heat the seawater, and then makes the seawater produce steam, so as to realize the desalination of seawater, so it is often necessary to reserve a large amount of diesel oil on board and other energy substances. [0003] When the whole ship is moving forward, the engine ...
