A wood gel-based integral solar seawater desalination device

Abstract

The invention relates to a wood-based integrated device for seawater desalination and solar energy collection, which is basically composed of a sunlight absorption and seawater supply module, a seawater desalination and collection and heat preservation module, an automatic light receiving position adjustment and water storage module, and a support and adjustment module. The sunlight absorption and seawater supply module is similar to the roof structure and is arranged on the upper part of the device to transmit sunlight and supply seawater. The sensor is located on the top to measure the change of light intensity; the seawater desalination and collection insulation module is wood or gel, which is located on the support seat. The upper part is positioned in an inverted funnel structure, and the sensors are respectively located on the upper part of the cavity and above the supporting seat plate; below it is the automatic adjustment of the light receiving position and the water storage module, which is used to store desalinated hot fresh water and adjust the light receiving position with the change of sunlight; the bottom layer The support and adjustment module is used for the adjustment of the height of the device and the fixing of the device. The device has the advantages of environmental protection, simple structure, comprehensive functions, convenient assembly and disassembly, adaptable adjustment of light receiving position, and low cost.

Description

technical field [0001] The invention relates to a solar seawater desalination device, in particular to an integrated solar seawater desalination device with low cost based on the water absorption of wood and gel and comprehensive utilization of solar energy. Background technique [0002] The earth's water storage is very rich, with a total of 1.45 billion cubic kilometers, and 72% of its area is covered with water, but 97.5% of the water on the earth is salt water, which cannot be used for drinking and irrigation, and is difficult to apply in industry. The water directly used by people for production and living is very little, only 2.5% of fresh water. In fresh water, nearly 70% is frozen in the Antarctic and Greenland ice sheets, and most of the rest is moisture in the soil or deep groundwater, which is difficult for humans to exploit. Water from sources such as rivers, lakes, reservoirs and shallow groundwater is easier to exploit for direct use by humans, but its amount ...
