Description

Solar Concentrator-Wind Energy Synergistic Ultrasonic Seawater Desalination Device

technical field

The utility model belongs to the field of energy technology, in particular to a solar ray concentration-wind energy synergistic ultrasonic seawater desalination device.

Background technique

With the progress of society, the development and improvement of industry, agriculture and civilian life, the demand for energy is increasing. The current situation of the world's energy structure is becoming more and more severe, climate change is becoming more and more obvious, environmental pollution is becoming more and more serious, and we are facing unprecedented challenges. , energy conservation and emission reduction are urgent, and there is an urgent need to develop new energy sources and more fresh water resources.

Basic research in the field of new energy seawater desalination technology focuses on:

①Passive desalination methods are driven entirely by solar energy and natural changes in environmental conditions, such as traditional solar distillation pools, multi-effect solar stills, multi-stage flash evaporation devices, etc.;

②The active desalination method requires a small amount of power consumption to prepare fresh water, and additional devices such as fans and pumps are also required to enhance heat and mass transfer effects and improve system performance;

③Wind energy and ocean energy drive air pressure and hydraulic pumps, combined with reverse osmosis seawater desalination and energy recovery;

④Realize cascade utilization of energy, composite systems for the comprehensive application of the above technologies and other related technologies, such as combining with solar greenhouses, combining with compressed gas distillation and flash evaporation, etc.

The active seawater desalination method has attracted much attention because it improves the heat and mass transfer effect of the desalination device, and the evaporation temperature and condensation temperature can be adjusted separately. The recovery of energy, water and salt in the seawater desalination process, the enhancement of heat and mass transfer process, the scaling characteristics of components, the improvement of energy utilization efficiency and water production rate are the focus of research. Advanced solar collectors are combined with distillation, flash evaporation, pressure steam distillation and other processes and various heat and mass transfer processes. Wind energy utilization is mainly used for wind power generation, and then drives hydraulic pumps for reverse osmosis seawater desalination.

my country's existing seawater desalination technologies mainly include thermal method, membrane method, and freezing method; thermal methods include multi-stage flash evaporation, multi-effect distillation, vapor compression, and solar distillation; membrane methods mainly include reverse osmosis and electrodialysis. wait. But at present, only multi-stage flash evaporation, multi-effect distillation, vapor compression and reverse osmosis have really formed an industrial scale. The multi-stage flash seawater desalination technology mainly has a large number of seawater circulation and fluid transportation, which requires a large heat transfer area, resulting in increased operating costs. In the multi-effect distillation method, due to the boiling of seawater on the heating surface, it is easy to scale on the wall of the heat transfer tube, which requires frequent cleaning and strict anti-scaling measures; the cost of the steam compression compressor is high, the equipment is easy to scale, and the scale is relatively large. Small. The main way of traditional wind energy seawater desalination is to first generate electricity from the fan, and then drive the compressor to generate high-pressure water for reverse osmosis seawater desalination. The efficiency loss of the secondary conversion of mechanical energy-electrical energy-mechanical energy and the existence of electric energy storage devices lead to low energy utilization. Increased costs.

Most of the existing seawater desalination projects use a single desalination technology, and are usually implemented in conjunction with the waste heat source of large power plants, which reduces operating costs due to the use of waste heat; as an independent seawater desalination project, each has its own problems, resulting in seawater desalination. Desalination projects have varying degrees of operational defects; and the construction of seawater desalination projects alone requires a lot of energy consumption, resulting in waste of energy and increasing the cost of water production.

At present, the development of the seawater desalination method itself and the integration between methods, the integration of new energy and seawater desalination technology, the deep integration of power generation-seawater desalination-comprehensive utilization, etc. are developing slowly, so that the advantages of each desalination method cannot be fully utilized and reasonable Utilize energy, reduce costs and obtain comprehensive benefits. The coordinated use of wind energy, solar energy, ocean energy and other energies for seawater desalination at the same time has not yet been carried out, let alone performance optimization.
