Description

technical field [0001] The invention relates to the field of seawater desalination, more specifically, to an automatic cleaning porous graphene seawater desalination device. Background technique [0002] In order to solve the problem of the increasing shortage of fresh water resources, people have turned their attention to seawater desalination. After years of hard work, seawater desalination technology has made a lot of progress, but so far, these technologies are superior to the high cost and cannot be widely applied. [0003] At present, the most commonly used desalination technology for seawater is reverse osmosis technology. Its working principle is to use reverse osmosis membrane (a special membrane to filter the salt in seawater), because the pores on these membranes are extremely dense (1000 times denser than porous graphene) ), requires a very large pressure to force seawater to pass through the membrane, therefore, the notice of desalination of seawater also needs ...
