Description

technical field [0001] The invention relates to the field of new energy equipment, in particular to a seawater desalination device based on tidal energy. Background technique [0002] Tidal energy refers to the gravitational force of the sun and the moon, as well as the centrifugal force generated by the rotation of the earth-moon system composed of the earth and the moon. The combined action of the two causes the water level potential energy difference formed by the continuous periodic change of the ocean water level. Tidal energy is the earliest ocean energy utilized by humans. The earliest report on the utilization of tidal energy can be found in about 1000 AD. The first countries to use tidal energy are Britain, France and Spain. Tidal energy is a renewable energy with the most mature technology and the largest utilization scale in marine energy. Ocean energy is characterized by intermittency and randomness. Compared with ocean energy such as offshore wind energy and w...

However, in this invention, the operation of seawater desalination is carried out by distillation, which not only consumes a lot of energy but also has low desalination efficiency. At the same time, in this device, only tidal energy is used to push the floating body, and the piston cylinder performs work and heat to realize distillation, and the utilization rate is low.
