Embodiment 1
[0037] A seawater desalination device, including a water intake system 1, a pretreatment system 2 and a seawater desalination and desalination system 3, each system is sequentially connected through pipelines; wherein,
[0038] The pretreatment system 2 includes a PP filter element filter device 21 and a pipeline-type NdFeB inner strong magnet 22, and the PP filter element filter device 21 is connected to the pipeline-type NdFeB inner strong magnet 22 through a pipeline; the PP filter element filters The device 21 is divided into two layers of decreasing filter layers inside and outside, the filter hole diameter of the outer filter layer is 5 μm, and the filter hole diameter of the inner filter layer is 1 μm; The width of the channel is adaptively adjusted between 0.5-0.7cm to form a narrow water flow channel, increase the water pressure, make the water flow cutting magnetic field strong, fully soften the heavy salt in seawater, and prevent scale formation on the reverse osmosi...
Embodiment 2
[0047] In terms of the technology of the specific embodiment 1 of the seawater desalination device described above, the PP filter element filter device 21 is subjected to quantum processing through the quantum chamber to inhibit microorganisms and algae; at the same time, the macromolecular bonds are broken to form a small molecular structure , to facilitate the decomposition of heavy salt molecules in the magnetic field.
[0048] Based on the above seawater desalination method, comprising the following steps:
[0049] (1) After the seawater is obtained, the seawater is input to the PP filter element filter device 21 for filtration, to filter out large particles, algae, and microorganisms in the seawater, reduce the turbidity of the seawater, and obtain the first pretreated seawater;
[0050] (2) Pass the first pretreated seawater through the NdFeB strong magnetic field to obtain the final pretreated seawater, in which the heavy salt ions decompose, and the softened sediment i...
Embodiment 3
[0054] In terms of the technology of the specific embodiment 1 of the above-mentioned seawater desalination device, the connecting pipe between the pipe-type NdFeB inner strong magnet 22 and the PP filter element filter device 21 is a curved pipe. Preferably, a 90° corner is set on the curved pipe near the entrance of the pipe-type NdFeB inner strong magnet 22 .
[0055] Based on the above seawater desalination method, comprising the following steps:
[0056] (1) After the seawater is obtained, the seawater is input to the PP filter element filter device 21 for filtration, to filter out large particles, algae, and microorganisms in the seawater, reduce the turbidity of the seawater, and obtain the first pretreated seawater;
[0057] (2) Pass the first pretreated seawater through the NdFeB strong magnetic field to obtain the final pretreated seawater, in which the heavy salt ions decompose, and the softened sediment is intercepted by the RO membrane and discharged with the wast...
