Simple marine seawater desalination apparatus

Abstract

The present invention provides a simple marine seawater desalination apparatus, which mainly comprises an internal combustion engine cooling system, a water cooling cooler, a condensing heat exchanger, a seawater evaporation device, a fresh water tank, a water pump and a fan. According to the simple marine seawater desalination apparatus, seawater is heated by the fresh water of the internal combustion engine cooling system; the marine internal combustion engine is subjected to closed water cooling, wherein circulation cooling is performed with the fresh water, and then the fresh water is cooled with the environmental seawater, such that the scaling and the corrosion on the heat exchange surface are avoided; and the environmental seawater enters the condensing heat exchanger and absorbs the condensed heat of the high temperature saturated wet air so as to be subjected to first heating, the seawater being subjected to the first heating enters the water cooling cooler and absorbs the heat of the fresh water in the internal combustion engine cooling system so as to be subjected to second heating, the obtained high temperature seawater enters the seawater evaporation device and is evaporated, heat and moisture exchange with the environmental air is performed, the obtained high temperature saturated wet air enters the condenser and is subjected to heat exchange and condensing with the environmental cold water, and the obtained fresh water flows into the fresh water tank. The simple marine seawater desalination apparatus of the present invention has characteristics of low energy consumption, low initial cost, low operating costs, simple structure, and easy promotion.

Description

technical field [0001] The invention relates to a seawater desalination device which utilizes the residual heat of cooling water in an internal combustion engine cooling system to desalinate seawater. Background technique [0002] With the rapid development of economy and society and the rapid increase of population, the water resource crisis has become the second largest environmental problem in the world after global warming. Seawater desalination is an inevitable choice to solve the water resource crisis and develop new safe water sources. [0003] Various seawater desalination technologies emerged as a result. The multi-stage flash technology is mature and reliable, but consumes a lot of power; The adaptability of sea water quality is limited, and the system stability still needs to be improved. [0004] Marine internal combustion engines can be fueled by diesel, gasoline, kerosene, etc. While the fuel is burning to do work, the temperature of the heated parts inside ...

Problems solved by technology

This invention mainly has two disadvantages, one disadvantage is that allowing seawater to flow directly through the inside of the water-cooled internal combustion engine will easily cause scaling and corrosion on the heat transfer surface, and once the scaling is formed, it is difficult to remove; The structure of the water-cooled internal combustion generator set has undergone structural transformation, and there are various limitations caused by it. The structure is complex and it is not easy to promote
