Novel electro-adsorption liquid treatment device

Abstract

The invention discloses a novel electro-adsorption liquid treatment device which comprises a cylindrical barrel, a conductive carbon rod, an anion-exchange membrane, a spacer, a cation-exchange membrane and flow-carbon electrolyte slurry. The conductive carbon rod, the anion-exchange membrane, the spacer, the cation-exchange membrane and the flow-carbon electrolyte slurry are all installed inside the cylindrical barrel. The novel electro-adsorption liquid treatment device has the advantages of simpleness and easiness in operation, meanwhile, requirements are not limited in large specific surface area, more gaps and the like on electrodes, electrode production is simple and convenient, regeneration capacity is high, and time and efficiency in electrode production can be increased. By combination of advantages of flow-electrode adsorption with membrane-electrode adsorption, the anion-exchange membrane and the cation-exchange membrane is introduced for isolation, so that adsorption efficiency and desalting efficiency are effectively improved; due to overall cylindrical design, simplicity is achieved, contact area is large, good mechanical effect is achieved, and use time of the device is prolonged.

Description

technical field [0001] The invention belongs to the technical field of electrochemistry, and in particular relates to a novel electro-adsorption liquid treatment device. Background technique [0002] Human production and life are inseparable from water. Water is the source of life and the foundation of social and economic development. In the 21st century, water resources are a precious and scarce resource. The problem of water resources is not only a resource problem, but also a major strategic issue related to the long-term stability and sustainable development of the national economy and society. With the improvement of people's living standards and the rapid development of the economy, people's demand for water is increasing, and the requirements for water quality are also gradually increasing. The lack of water resources, uneven distribution, unrestricted exploitation, unrestrained waste and serious pollution have made the already scarce water resources more tense. [...

Problems solved by technology

Appropriate electrode materials are the core of capacitive deionization technology. Commonly used electrode materials mainly include: activated carbon, carbon fiber, graphene, carbon aerogel, etc., but because electrode materials usually have a developed pore structure and abundant surface functional groups, so in During the desalination process, a small amount of physical adsorption and chemical adsorption will also occur. When these non-static adsorptions exist, the reverse power supply cannot achieve electrode regeneration, resulting in electrode oxidation failure.

At the same time, capacitive desalination technology also has shortcomings such as short cycle time and long desorption time, which affect industrial applications.
