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

In the device, nanometre carbon tube is used as electrode material. The characteristics are: a couple of combination electrodes composed by nanometre tube which shared collecting electrode is in middle of its core parts of the device, there is a layer of insulate textile film is fixed between said combination electrodes, two weather board with notch are fixed at out side of said combination electrodes separately, sea water to be processed is send into water container through the notch on weather board from bottom water entrance and into upper weather board in way of circuitous liquid flow. There is an isoelectrode on and stick out the electrides, seal water-proof rubber grommers are fid on bottom and top of the water container, central core parts is fixed by steel plate frame arounding it and screwing up bolt and nut.

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...
