本实用新型的海水淡化装置，其工作原理为：系统中动力的来源是利用槽式太阳能装置加热海水，加热的海水流进蒸发器内的铜管中，热水经铜管流至槽式太阳能装置继续加热循环利用。经过过滤的海水，通过布液器布液后润湿蒸发器中的铜管，与铜管中流动的热水进行换热，控制蒸发器内的压力，过滤后的海水在蒸发器内进行降膜蒸发，降膜后的海水在自激淋横管降膜蒸发-冷凝器中重复蒸发器的过程，而蒸汽进入自激淋横管降膜蒸发-冷凝器进行冷凝，部分冷凝水和部分蒸汽从自激淋横管降膜蒸发-冷凝器进入到冷凝器进行冷凝。The working principle of the seawater desalination device of the present invention is: the source of power in the system is to use the trough solar device to heat seawater, the heated seawater flows into the copper tube in the evaporator, and the hot water flows to the trough solar energy through the copper tube. The device continues to heat and recycle. The filtered seawater wets the copper tube in the evaporator after distributing liquid through the liquid distributor, exchanges heat with the hot water flowing in the copper tube, controls the pressure in the evaporator, and the filtered seawater is reduced in the evaporator. Film evaporation, the seawater after the falling film repeats the process of the evaporator in the self-excited horizontal tube falling film evaporation-condenser, and the steam enters the self-excited horizontal tube falling film evaporation-condenser for condensation, part of the condensed water and part of the steam From the self-excited horizontal tube falling film evaporation-condenser into the condenser for condensation.
一定适量的海水经过预处理后，流经槽式太阳能装置集热加温水，此热水流到蒸发器中蛇形管道中与降膜的海水换热循环回到槽式太阳能集热系统中，此热水循环为整个装置提供能量来源。装置的海水进水口的原海水经过预处理再经过第二过滤器过滤后，第二过滤器把水中的大颗微粒进一步过滤，这样避免了降膜后的海水堵塞管道，提高了海水淡化装置中水循环的效率，原海水经一效蒸发器中降膜蒸发后，产生的蒸汽进入自激淋横管降膜蒸发-冷凝器的横管中，降膜后一定浓度的海水经过二效降膜蒸发兼顾冷却一效进入横管的蒸汽，充分利用了降膜后海水的余热，与自激淋横管降膜蒸发-冷凝器的横管中的蒸汽换热后进一步蒸发，蒸汽进入冷凝室与冷却水换热冷凝，自激淋横管降膜蒸发-冷凝器横管中未冷凝的气体经冷凝室进一步冷却。合理调节蒸发器、自激淋横管降膜蒸发-冷凝器、冷凝器的压力，经降膜蒸发后的水蒸气，由真空泵同时抽取蒸发器和自激淋横管降膜蒸发-冷凝器，后返回到自激淋横管降膜蒸发-冷凝器，在真空泵抽取的过程中，采取两个阀门去调节两室之间的压力，这样解决了蒸发器中蒸汽没有压力差的作用很难到自激淋横管降膜蒸发-冷凝器中的问题；在蒸发和冷凝的物理过程中，一部分蒸汽在壁面冷凝成水，与降膜后的海水混为一起，造成浪费，因此在蒸发器和自激淋横管降膜蒸发-冷凝器的内壁面设置淡水收集槽收集此部分凝结的淡水。After a certain amount of seawater is pretreated, it flows through the trough solar device to collect heat and heat water, and the hot water flows into the serpentine pipe in the evaporator to exchange heat with the falling film seawater and return to the trough solar heat collection system. This hot water circulation provides the energy source for the entire unit. The raw seawater at the seawater inlet of the device is pretreated and then filtered through the second filter. The second filter further filters the large particles in the water, which avoids the seawater after falling film from clogging the pipeline and improves the efficiency of the seawater desalination device. The efficiency of the water cycle, the original seawater is evaporated by the falling film in the first effect evaporator, and the steam generated enters the horizontal tube of the self-excited horizontal tube falling film evaporation-condenser, and the seawater with a certain concentration after the falling film is evaporated by the second effect falling film Taking into account both cooling and one effect, the steam entering the horizontal tube makes full use of the waste heat of seawater after the falling film, and exchanges heat with the steam in the horizontal tube of the self-excited horizontal tube falling film evaporation-condenser to further evaporate, and the steam enters the condensation chamber and the cooling chamber The water is heat-exchanged and condensed, and the self-excited horizontal tube falling film evaporation-the uncondensed gas in the horizontal tube of the condenser is further cooled by the condensation chamber. Reasonably adjust the pressure of the evaporator, the self-excited shower horizontal tube falling film evaporation-condenser, and the condenser. After returning to the self-excited horizontal tube falling film evaporation-condenser, in the process of vacuum pump extraction, two valves are used to adjust the pressure between the two chambers, which solves the problem that the steam in the evaporator has no pressure difference and is difficult to achieve Self-excited horizontal tube falling film evaporation-a problem in the condenser; in the physical process of evaporation and condensation, a part of the steam condenses into water on the wall and mixes with the seawater after the falling film, causing waste, so in the evaporator and A fresh water collection tank is arranged on the inner wall of the self-excited horizontal tube falling film evaporation-condenser to collect the partially condensed fresh water.
上述所列具体实现方式为非限制性的，对本领域的技术人员来说，在不偏离本实用新型范围内，进行的各种改进和变化，均属于本实用新型的保护范围。The specific implementation methods listed above are non-restrictive. For those skilled in the art, various improvements and changes made within the scope of the present utility model all belong to the protection scope of the present utility model.
