Making method for charcoal electrode of liquid flow type electroadsorption desalinization device

Abstract

The invention relates to a method of making carbon electrode of fluid electric-absorption desalter. It mainly mixes high specific surface area electrode carbon, nano carbon tube absorption material, carbon fiber, and nano carbon tube conductive material as well as adhesive polytetrafluoroethylene in a certain proportion and in a certain mode to make cold press molding and makes them into a double-faced electrode with a collector interlaid; the carbon electrode has good electric conductivity, small resistance, large electric capacity and low energy consumption; in addition, the modified carbon electrode has larger specific surface area and mesoporous porosity, therefore able to increase the absorption quantity of electrode to salt ions. The carbon electrode is especially applied to the fluid electric-absorption desalter and has higher desalting efficiency.

Description

Technical field:

[0001] The invention relates to a method for manufacturing a carbon electrode of a liquid flow type electro-absorption desalination device, that is to say, to a method for obtaining a modified carbon electrode suitable for liquid flow type electro-absorption water treatment. The invention belongs to the technical field of the manufacturing process of the main component carbon electrode in an electro-absorption water treatment device. Background technique:

[0002] The water treatment method of liquid flow electro-absorption desalination uses carbon materials as electrodes, and uses components such as collectors, diaphragms, and outer frames to form electro-absorption devices. The main working principle is that when the salt water passes through the device under the condition of electrification, the soluble salt ions in the water move to the oppositely charged electrode and are adsorbed on the electrode. When the electrode reaches the saturation adsorption, it is ...
