Abstract

The invention discloses a seawater desalination parallel device based on ion concentration polarization effect, which can be mainly divided into three modules: an anode chamber, a desalination chamber and a cathode chamber. The parallelism of the device is reflected in two aspects. First, the parallelism of the micron holes made of ion-selective membrane in the cavity of the desalination chamber; second, the parallelism of the desalination chambers. In order to fully describe the device, we also added the cathode chamber and the anode chamber, and described in detail the whereabouts of anions and cations in the whole device and the maintenance of the electrical neutrality of the system. The whole device can operate stably for a long time, and the three units perform different functions: the anode chamber is responsible for neutralizing the excess anions in the system, the cathode chamber is responsible for neutralizing the excess cations in the system, and the desalination chamber is selected by the cation selective membrane Permeability, to achieve the effect of seawater desalination. The device provides a complete and comprehensive parallel method of seawater desalination, which can be flexibly applied to seawater desalination industries of various scales.

Description

technical field [0001] The invention belongs to the field of seawater desalination equipment, and specifically refers to a parallel device for desalination of seawater based on ion concentration polarization effect. Background technique [0002] With the growth of population and the development of economy, the problem of water shortage in the world is becoming more and more serious. Since seawater resources account for about 97% of the total water resources, desalination of seawater into fresh water is one of the main means to solve the shortage of water resources. The existing seawater desalination technologies are mainly divided into two types: membrane method and distillation method, among which membrane method is mainly divided into electrodialysis method and reverse osmosis method, and distillation method can be divided into multi-effect flash method and multi-effect distillation technology. Reverse osmosis technology is the most mainstream seawater desalination techno...
