AI Technical Summary

Problems solved by technology

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

[0010] 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; building seawater desalination projects alone consumes a lot of energy, resulting in waste of energy and increasing the cost of water production

[0011] 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 energy for seawater desalination has not yet been carried out, let alone research on performance optimization
