Marine solar seawater desalination power-generating set

Abstract

A marine solar seawater desalination power-generating set is characterized by comprising a heat collector rack, a heating tank and a fresh water collector tank; parabolic mirrors are evenly distributed on the heat collector rack; heat collector tubes are mounted on the parabolic mirrors, two ends of very heat collector tube are connected with two liquid pumps, and a circulating pipeline running through the heating tank is connected between the liquid pumps; compared with the prior art, the marine solar seawater desalination power-generating set has the advantages that heat transfer oil in the heat collector tubes is heated by solar energy and may be heated up to 400 DEG C, seawater in the heating tank is heated and distilled through the circulating pipeline such that energy is saved, the marine solar seawater desalination power-generating set is handy, small in size, small in floor area and energy-saving and is green since all power for the set is from solar energy.

Description

technical field [0001] The invention belongs to the technical field of environmental protection machinery, and in particular relates to a solar seawater desalination power generation device for ships. 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, which can increase the total amount of fresh water without being affected by time, space and climate, and can guarantee stable water supply such as drinking water for coastal residents and replenishment water for industrial boilers. [0003] The process of obtaining fresh water from sea water is called desalination. Currently used seawater desalination methods include seawater freezing method, electrodialysis method, distillation method, and reverse osmosis method. At present, the reverse osmosis method using reverse osmosis membrane quickly occupies the market due to its advan...

Problems solved by technology

[0007] At present, the existing solar seawater desalination power generation devices for ships are mainly divided into two types: 1. The main disadvantages of passive solar distillation systems: 1) The latent heat of steam has not been reused; 2) The heat capacity of seawater is too large; 3) The device The internal natural convection mode limits the improvement of device performance; 2. The main disadvantages of the active solar distillation system: 1) The equipment cost is relatively high; 2) It needs to consume a certain amount of electric energy, which is not conducive to the use of remote island residents

At the same time, both of the above two methods need to consume electric energy to drive the equipment to desalinate, which will consume a lot of energy, which is a big burden for ships in navigation.
