Solar-powered seawater desalination generation device for ships

Abstract

A solar-powered seawater desalination generation device for ships is characterized by comprising a heat collecting rack, a heating tank and a fresh water collecting tank, wherein parabolic mirrors are uniformly mounted on the heat collecting tank; a heat collecting pipe is mounted on the parabolic mirrors, two extraction pumps are connected with two ends of the heat collecting pipe, and a circulating pipeline penetrating through the heating tank is connected between the two extraction pumps. Compared with the prior art, the solar-powered seawater desalination generation device for the ships has the advantages as follows: heat transfer oil is heated by solar energy, the heat transfer oil in the heat collecting pipe can be heated to 400 DEG C to the highest extent, seawater in the heating tank is heated and distilled through the circulating pipeline, and energy is saved; the device is simple and small and exquisite in appearance, occupies a small area, and has an energy-saving effect, all energy is provided by solar energy, and the device is green and environment-friendly.

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.
