Solar-powered seawater desalination power generation device for ships

Abstract

The invention discloses a solar-powered seawater desalination power generation device for ships. The device is characterized by comprising a heat collection rack, a heating box and a freshwater collection box, wherein parabolic mirrors are installed on the heat collection rack in an evenly distributed mode; a heat collection pipe is installed on the parabolic mirrors, the two ends of the heat collection pipe are connected with two infusion pumps, and a circulating pipeline penetrating through the heating box is connected between the two infusion pumps. Compared with the prior art, the device has the advantages that solar energy is adopted for heating conduction oil, the conduction oil in the heat collection pipe can be heated to 400 DEG C to the maximum, seawater in the heating box is heated and distilled through the circulating pipeline, and therefore energy is saved; the device is easy and convenient to use, small in appearance and small in occupied area and has an energy saving effect, and all energy is supplied by the solar energy, so that the device is environmentally 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...

AI Technical Summary

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.
