Description
Technical Field
The invention relates to the field of seawater desalination, in particular to a solar photo-thermal evaporation steam collecting device.
Background
The sea water desalination is essentially a water-salt separation process, and the traditional sea water desalination technology has two types: one is a high-efficiency heat-driven seawater desalination technology, such as low-temperature multi-effect seawater desalination (LT-MED) and multi-stage flash evaporation (MSF); another class is pressure driven membrane desalination technology, typically reverse osmosis membranes (RO). Both of these types of processes are very sophisticated large-scale, centralized water supply solutions, but are also limited by the following factors: firstly, a large amount of high-grade energy such as heat energy or electric energy is required to be consumed, the greenhouse effect and the environmental pollution are inevitably aggravated, large-scale electric and thermal facilities are highly depended on, and the capacity and the distribution place are limited; and secondly, the salinity pollution equipment is a common problem in the traditional seawater desalination field, and the maintenance cost of the equipment is higher. Due to the factors, the traditional seawater desalination technology is generally applied to large-scale and centralized scenes and cannot meet the requirements of small-scale or field portable scenes such as islands, offshore platforms, ships and the like.
In order to reduce energy consumption, researchers combine renewable energy with seawater desalination, and propose some novel seawater desalination technologies, such as RO seawater desalination technology based on a hybrid renewable energy system, seawater desalination membrane technology driven by renewable energy, and seawater desalination technology combining a reverse osmosis membrane with a solar still. Under the guidance of the latest 'double-carbon' policy, the solar energy is utilized to desalt the seawater, so that the method has the advantages of no consumption of conventional energy, zero carbon emission, high purity of fresh water and the like, and becomes a focus of common attention in the fields of energy, environment and water resources. In a conventional solar driven water evaporation system (solar still), heat is generated at the surface of the absorber, raising the water temperature as a whole, while steam is generated elsewhere in the system, thus causing the absorber and the evaporation surface to separate and generate a certain temperature difference, resulting in a large amount of heat loss, with an evaporation efficiency of only 30-45%.
In recent years, the Solar local heating technology has developed in recent years to become a brand new type of Solar seawater desalination technology, namely Solar-driven interfacial evaporation (Solar-driven seawater desalination), which is a brand new type of Solar seawater desalination technology and has the advantages of higher photothermal conversion efficiency, larger scale and lower cost. Different from the traditional evaporation system based on integral heating, the interface evaporation system consists of an interface evaporator and a condensation collector, a small amount of water is isolated from the lower water body, sunlight-heat energy conversion is limited to an air-isolated water interface, only the water at the interface is heated and evaporated, heat loss is greatly reduced, the photothermal-steam conversion efficiency higher than 80% is easily realized, and fresh water can be obtained after steam is condensed and collected. The solar driven interface evaporation mostly adopts a mode of steam natural upward evaporation, and a typical interface evaporator basically adopts a double-layer structure design, namely a lower water conveying layer and a light and heat layer loaded on the lower water conveying layer. The water conveying layer plays the roles of conveying water, floating, insulating heat and supporting photo-thermal materials, and generally conveys seawater to an evaporation interface through capillary action; the photothermal layer is a solar energy absorbing material, converts light into heat, heats and evaporates a small amount of water at an evaporation interface, and simultaneously ensures that a large amount of water is not contacted. The solar-driven interface evaporation technology can continuously obtain fresh water only by depending on solar energy, two major restriction factors of the traditional seawater desalination technology are eliminated to a certain extent, and the solar-driven interface evaporation technology is determined to be suitable for large-scale centralized water supply systems and miniaturized portable devices, and has great potential in the aspect of sea island and ship water use guarantee.
However, the solar driven interface evaporation, since the steam naturally goes upwards, the steam will condense on the top cover, which results in a significant energy loss, for the following reasons: firstly, vapor mist and water droplets condensed on the transparent top cover can cause serious light scattering loss (up to 35%); secondly, because of the requirement of optical transparency, the top cover is usually made of polymer (such as acrylic, etc.) or glass, and these materials generally have 5 to 20 percent of optical loss due to the limitation of self-transmittance, and the thermal conductivity coefficient K is low (K<5W m -1 K -1 ) Is not favorable for steam condensationThe required exothermic process of liquefaction; thirdly, the temperature of the top cover can be raised by direct solar radiation and heat released by steam liquefaction, and the subsequent condensation effect is further influenced.
Steam is after the top cap condenses, through collecting and obtains high-purity drinking water, and current light and heat drive interface evaporation and collection configuration scheme adopts the scheme that natural liquid drop rolls or artificial vibrations make the condensed drop of top cap drip more, and this will bring two adverse effects: (1) The liquid drops on the top cover are dripped on the photothermal surface in a rolling way, and the liquid drops fall back into the evaporation layer to bring secondary evaporation of the photothermal layer, so that the temperature of the evaporation layer is reduced, the evaporation efficiency is reduced, the liquid backflow direction is opposite to the supply direction of the water supply channel, and the continuous water delivery of the water supply channel is influenced; (2) The solution of artificial vibration requires human intervention at intervals, which is not only inconvenient, but also directly affects the collecting effect each time the vibration amplitude and frequency are different, and is not suitable for large-scale equipment. Therefore, by the configuration scheme of condensation and collection, most of steam cannot be effectively converted into collected fresh water, so that the comprehensive solar energy conversion efficiency of the solar photo-thermal evaporation seawater desalination system is lower than 50%.
In summary, if the solar photo-thermal evaporation seawater desalination system needs to work efficiently and stably and continuously and efficiently collect fresh water, the problems that steam is not easy to condense and condensed water is not easy to roll and collect and the solar energy utilization rate is low due to the fact that the steam is required to be condensed and collected on the top cover after evaporation are solved.

To the inside gas blowing of air current spoiler, collect at the lateral wall condensation, only need to carry out optimal design to the material, the heat conductivility of collection device inner wall can. For the collection of the air flow disturber by exhausting air outwards, the material and the heat-conducting property of the collection device are not even required to be optimally designed. Therefore, the invention can greatly simplify the requirements of the whole device on material and heat-conducting property and reduce the manufacturing cost.
