Description

Technical Field

[0001] This invention belongs to the field of new energy and water resource treatment technology, specifically a high-efficiency solar interface water evaporation and condensation device driven by both solar thermal and photovoltaic processes. Background Technology

[0002] With the increasing severity of global warming and water scarcity, the development of green and efficient water treatment technologies has become increasingly urgent.

[0003] Solar energy, as a clean and renewable energy source, has broad application prospects in the field of water treatment. In recent years, solar interface water evaporation technology has received widespread attention as a novel water treatment technology. This technology utilizes photothermal materials at the water-air interface to convert solar energy into heat energy while reducing heat conduction losses, resulting in a high water evaporation rate. This technology also features low cost, simple operation, and environmental friendliness, demonstrating great application potential in the water treatment field. Based on the technical characteristics of solar interface water evaporation, the design of solar interface water evaporators has been continuously improved, leading to the emergence of a variety of solar evaporators, such as separate solar evaporators, multi-stage solar evaporators, three-dimensional solar evaporators, and electrically assisted solar evaporators, significantly increasing the water evaporation rate.

[0004] However, current designs for solar interface water evaporators primarily focus on increasing the water evaporation rate. Their water treatment efficiency is also affected by the water vapor condensation rate, and increasing the condensation rate is gradually becoming one of the major technical challenges limiting the development of solar water evaporation technology. Currently, in many solar interface water evaporators, water vapor condenses on a transparent glass cover. The formation of a large number of condensate droplets leads to a decrease in the light transmittance of the glass cover, thus reducing the water evaporation rate. This is also a significant technical problem hindering the design of solar interface water evaporators. Furthermore, for two-dimensional photothermal evaporation films, the water evaporation rate is limited to 1.46 kg•m. -2 •h -1 The theoretical extreme value of the water evaporation rate needs to be explored, and new solutions need to be found to further improve its water evaporation rate.

[0005] Therefore, in view of the above-mentioned shortcomings of the current solar interface water evaporation technology, we urgently need to develop new devices to overcome the above technical problems, so as to efficiently utilize solar energy and improve water treatment efficiency.

A refrigeration plate 16-2 is provided at the middle position of each of the four sides of the rectangular refrigeration block 16-1. The outer ends of the four refrigeration plates 16-2 are fixedly connected to the bottom periphery of the condenser 12 by resin glue.

A heating plate 18-2 extends outward from each of the four corners of the rectangular heating block 18-1. An n-shaped hanging plate 18-3 is provided at the outer end of each heating plate 18-2. The outer side plate of the n-shaped hanging plate 18-3 is embedded in the annular groove 11 and connected to the heat-conducting copper wire in the double-layer transparent glass cover 1. The inner side plate of the n-shaped hanging plate 18-3 is clamped on the inner surface of the side wall of the internal water storage area 6.

The temperature of each component is controlled by the semiconductor cooling chips, thereby achieving a higher water evaporation rate at the solar thermal interface. The increased temperature of the hot surface of the upper cooling chip 15 heats the solar thermal film within the insulation dam 13, further increasing the water evaporation rate. The cold surfaces of the upper and lower cooling chips 15 and 17 cool the condenser 12 through the cooling heat conduction bridge 16, thereby promoting the preferential and rapid condensation of water vapor on the surface of the condenser 12, further increasing the distilled water production. The hot surface of the lower cooling chip 17 heats the double-layer transparent glass cover 1 through the heating heat conduction bridge 18, thereby suppressing water vapor condensation on the surface of the double-layer transparent glass cover 1 and avoiding the problem of water condensation and light blocking on the surface of the double-layer transparent glass cover 1. Meanwhile, the outer surface of the condenser 12 is designed as a mirror structure, which can reflect sunlight onto the double-layered transparent glass cover 1, further increasing the temperature of the double-layered transparent glass cover 1. The double-layered transparent glass cover 1 has a double-layered heat insulation structure, which can avoid the influence of ambient temperature, thereby maintaining the high temperature effect of the inner layer of the glass cover.
