Description

technical field [0001] The invention belongs to the field of fluid transportation, and the invention relates to an ultra-high pressure pumping system that directly utilizes breeze energy or utilizes stored air energy, and is especially suitable for abandoning wind to store compressed air in the field of renewable energy, utilization of low-speed wind resources, or utilization of valley peaks Seawater desalination is performed with low-priced electricity in the power supply system. Background technique [0002] In the context of the increasingly severe domestic water shortage, seawater desalination has become one of the alternatives to solve the freshwater crisis. No matter which technology is adopted, the cost of seawater desalination is a major problem that human beings cannot get around. Extracting fresh water from seawater consumes energy, and desalination is a typical energy-intensive industry, no matter how this energy is obtained. This makes the energy consumption an...

Problems solved by technology

[0008] In the published patent "A Seawater Desalination System Directly Utilizing Wind Energy and Its Control Method" announcement number CN102627339B, a very good way to directly utilize wind energy is proposed, but the fly in the ointment is that the wind must be blown every year during the work process. In the middle of thousands of hours, if there is a long interval of wind energy, or if there is a slight change in intensity, or when the wind force is too strong, it is necessary to stop the wind compression and stop the operation of related pumps. When there is insufficient wind energy such as breeze, the system will also Desalination of seawater cannot be performed, which will cause idle equipment and lower production efficiency. If the wind is strong, wind energy cannot be utilized to the maximum extent and needs to be vented to absorb it. In addition, the low-priced power of the peak power supply of the power system cannot be used. Seawater desalination is carried out, so that the operating rate of the seawater desalination equipment is low in areas with low annual average wind speed and short windy time
