Solar energy and wind energy complementary-driving multiple-effect salifarous water desalting device based on disk type light condensation

Abstract

The invention provides a solar energy and wind energy complementary-driving multiple-effect salifarous water desalting device based on disk type light condensation. The device can achieve effective switchover between solar energy driving and wind energy driving through structure change of a disk type light condenser. The lower half part of a stirring blade is sprayed into black, the stirring bladeis arranged in an evaporating cavity and is connected with the disk type light condenser through a rotating shaft and a rotating arm, a hemispherical glass shell is arranged at the bottom of the evaporating cavity, a secondary parabolic light condenser is arranged outside the hemispherical glass shell, a focal spot of the parabolic light condenser is arranged at the hemispherical glass shell, thehemispherical glass shell is arranged at the focal spot position of the disk type light condenser, salifarous water containing a lot of black porous light absorption particles is accommodated in theevaporating cavity, high-density light energy formed by reflection of the light condenser is directly absorbed, and the salifarous water is heated and evaporated to generate fresh water on the lower surfaces of condensation disks. The device utilizes the characteristic that heated water vapor floats and rises upwards, so that a plurality of the water accommodating condensation disks are distributed in the water vapor floating and rising direction, latent heat released by water vapor condensation is recycled for many time, and graded and repeated utilization of heat contained in the water vaporis achieved.

Description

technical field [0001] The invention relates to a brine desalination device, in particular to a multi-effect brine desalination device, which belongs to the technical field of complementary utilization of solar and wind energy. Background technique [0002] Safe and sufficient fresh water is one of the necessary conditions for human progress and social development. Although 70% of the earth's surface is covered with water bodies, 97.5% of them are salt water that cannot be directly drunk. Desalination of salt water is an effective solution to the fresh water crisis. one of the ways. Industrial brine desalination treatment technologies mainly include reverse osmosis, multi-stage flash evaporation, multi-effect distillation, etc., but the driving energy required in the process of brine treatment is mainly fossil energy, and large-scale operation and construction costs are required. It is large, requires high maintenance, and releases a large amount of greenhouse gases. It is ...

Problems solved by technology

However, the solar desalination technology cannot overcome the unavoidable intermittent energy supply problem in the utilization of solar energy. Considering that wind energy, which is also a renewable energy source, can be driven complementary to solar energy in terms of energy supply time and method, thus improving the energy content of renewable energy. The technical bottleneck of intermittent energy supply during the operation of brine desalination plant

[0004] Patent application 201610160581.4 proposes a wind-solar seawater desalination device, which uses wind energy to generate electricity and then stores it in the battery for use, making the process of converting the collected wind energy into heat energy complicated, resulting in low energy conversion efficiency of the system

Patent 201310164208.2 relates to a solar-wind energy low-pressure seawater desalination device. Solar energy and wind energy are used to generate electricity to drive the air extraction device to provide a low-pressure environment for seawater evaporation, but the system does not recover the latent heat released by steam condensation multiple times.
