Problems solved by technology

The above-mentioned U.S. patents have all mentioned activated carbon with high specific surface area as electrode material, but this electrode usually has the disadvantages of these two aspects: 1) although activated carbon has a large specific surface area, because its micropores account for the vast majority, so In fact, the effective surface area that the solution ions can immerse is relatively low; 2) The resistivity of activated carbon is usually large
In the Chinese patent CN1308348A, a supercapacitive capacitor doped with carbon nanotubes is mentioned, but there is no research on the electrodes of seawater desalination devices

Abstract

A fluid-flow capacitance-type seawater desalination apparatus and its manufacture are disclosed. The apparatus is taken carbon nanometer tube as electrode materials, it is characterized by assembled electrode is made up of a pair of carbon nanometer tube electrode pieces with shared electrode as core element, a layer insulating fabric separating membrane is set between a pair of assembled electrodes, water-guiding panel are set at the external side of a pair of assemble electrodes separately, notch is opened on water-guiding panel, the treated seawater can enter into water container from bottom water inlet by notch of water-guiding panel with snaking liquid-flow way to top of water-guiding panel and be communicated with notch to flow water out, isoelectrode is extended from top of electrode, sealed water-proof rubber carrier rings are arranged at the top and bottom of container separately, and core element in the middle is fixed by periphery steel panel stand and pressed bolt and nut. It has simple structure, less consumption, high desalination efficiency and long life.

Description

technical field [0001] The invention relates to a liquid-flow capacitive seawater desalination device using carbon nanotubes and a manufacturing method thereof, belonging to the technical fields of seawater treatment and electrochemistry. Background technique: [0002] Seawater desalination, also known as seawater desalination, is a process in which salt in seawater is removed and desalinated through devices and equipment. The existing seawater desalination methods mainly include distillation, including multi-stage flash evaporation (MSF), multi-stage evaporation (MED) and compressed gas distillation (VC), and membrane methods, including reverse osmosis (SWRO) and electrodialysis (ED). [0003] U.S. Patents US5538611, US6413409, US5547581 and other documents mention the liquid flow capacitive seawater desalination method, which utilizes the principle of an electric double layer and uses carbon materials as electrode materials to form an electrosorption device. The main work...
