Solar-powered seawater desalination generation device for ship

Abstract

The invention relates to a solar-powered seawater desalination generation device for a ship. The device is characterized by comprising a heat collecting frame, a heating box and a fresh water collecting tank, wherein parabolic lenses are uniformly distributed on the heat collecting frame; heat collecting tubes are arranged on the parabolic lenses; the two ends of the heat collecting tubes are connected with infusion pumps; the quantity of the infusion pumps is 2; a circulating pipeline which penetrates through the heating box is connected between the two infusion pumps. Compared with the prior art, the solar-powered seawater desalination generation device for the ship has the advantages that the solar energy is adopted for heating the heat conductive oil, the heat conductive oil in the heat collecting tubes can be heated to 400 DEG C at most, the circulating pipeline is adopted for heating and distilling the seawater in the heating box, thus saving the energy resource; the device is simple and convenient, the size is small, less area is occupied, the energy-saving effect is achieved, and all the energy is supplied by solar energy, thus achieving the green and environment-friendly effects.

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.
