基于太阳能与尾气废热利用的渔船用海水淡化装置设计
Design of desalination unit for fishing vessels with combination of solar energy and waste heat
摘要
Abstract
In order to solve the crews'drinking water problems of the small-and medium-size fishing vessels and improve the quality of drinking water , a sea water desalination unit which works through the combination of diesel engine exhaust heat and solar energy .The unit consists of diesel , solar air collector , shell-and-tube seawater evaporator , plate-type heat exchanger .The primary heat source of this unit is diesel engine waste heat and solar energy .Heat and mass exchange operates between the exhaust gas and seawater though the evaporator, meanwhile the hot air of auxiliary solar collector bubbles and humidifies with seawater though the aeration tube , and then the water vapor produced by the plate heat exchanger condenses into freshwater . Diesel exhaust emissions , temperature and the temperature difference have a great influence on water production capacity .When the temperature of the exhaust gas outlet maintain 150-250 ℃, water production capacity increases gradually along with the increase of the temperature .If the exhaust gas temperature at 208℃is maintained, desalination unit will make water-producing rate continued at 20kg/h, it is able to meet 8 to 10 crews'living needs of the small-and medium-size fishing vessel .关键词
