Description
Technical Field
The invention relates to the technical field of seawater detection, in particular to a water salinity sampling and detecting integrated device based on ocean osmotic energy.
Background
The seawater power generation method is mainly a 'permeation method'. The so-called "osmosis process" is a process using a pressure boost to accelerate the seawater osmosis process. In the demonstration experiment, after the seawater and the pure water are separated in the container by the scientific household special film, the pressure of the seawater side to the film is higher than that of the pure water side. Then, a part of the pure water flows out of the water tank through the film, and generates huge power capable of driving the hydroelectric generator to operate, thereby generating electricity. In the osmotic power generation technology, the manufacture of membranes is of central importance. Acceptable films must have good water permeability, durability, and the ability to prevent salt passage to the greatest extent possible. Currently, some scientists use charged membranes to accelerate the permeation of fresh water into seawater. In order to prolong the service life of the film, researchers must also switch the position of the positive and negative electrodes of the electro-film in real time. Like the demonstration experiment, if a large one-way permeable film is used at the entrance of a river to separate river water from seawater, huge seawater osmotic pressure can be obtained to push a huge turbine to generate electricity.
It is worth mentioning that the seawater osmotic pressure power generation method is a very environment-friendly power generation mode, and because the seawater osmotic pressure is an energy source obtained from a natural physical process, no by-product polluting the environment is generated, and carbon dioxide is not emitted.
