High pressure electrostatic type ion spraying type seawater demineralizer and seawater desalination method thereof

Abstract

The invention discloses a high pressure electrostatic type ion spraying type seawater demineralizer. The high pressure electrostatic type ion spraying type seawater demineralizer comprises positive high voltage pole plates which are mutually parallel and are successively vertically arranged above a zwitterion compounding groove, an anion collection insulation disc, a cation collection insulation disc and a negative high voltage pole plate, wherein the anion collection insulation disc and the cation collection insulation disc both rotate around the self shaft line, and the lower parts of the anion collection insulation disc and the cation collection insulation disc stretch into the zwitterion compounding groove; and an insulation water-passing pipeline is horizontally arranged between two ion collection insulation discs, and the two sides of the insulation water-passing pipeline are respectively provided with an ion nozzle. The invention also discloses a seawater desalination method. According to the invention, electrostatic attraction of a high pressure electrostatic field is adopted to separate zwitterion in seawater, the ion concentration of the ion collection insulation discs is greatly improved, and the separation efficiency of seawater ions is improved; and the hydrophobicity property of a hydrophobic insulation surface is fully utilized, the fresh water, the seawater as well as high salinity seawater are isolated, thereby realizing practical segregation of the seawater and the fresh water.

Description

technical field

[0001] The invention relates to a seawater desalination device and a seawater desalination method thereof, in particular to a high-voltage electrostatic ion spray type seawater desalination device and a seawater desalination method thereof. Background technique

[0002] The fresh water resources of human beings are getting less and less, while the demand is increasing. Seawater desalination is an effective way to solve the shortage of water resources.

[0003] At present, there are patents showing that: when the water pipe is placed in a static strong magnetic field, when the brine flows at high speed in the pipe, the positive and negative ions in the brine are separated by the Lorentz force in the opposite direction, so that the water is desalinated. However, the flow velocity of the seawater in the pipeline is required to be high, so the required water pressure is high, the energy consumption is large, and the efficiency is low. When flowing at high speed...
