Electron exchange treatment device for reducing liquid conductivity

Abstract

The invention relates to an electric ion replacement processing device for reducing liquid conductivity, which comprises an electrode group, a box body and a back flush pipe, wherein the electrode group is arranged in the box body; the back flush pipe is arranged above the electrode group; the electrode group comprises a plurality of electrodes; any two adjacent electrodes are respectively connected with a positive pole and a negative pole of a power supply; the electrodes are made of materials having conduction or adsorption action; and the materials at least include one of carbon fiber cotton and charcoal fiber cotton. The carbon fiber cotton and charcoal fiber cotton are loose in structure, and a solution can be impregnated into gaps among the fibers, so that all the surfaces of all the carbon fiber cotton and charcoal fiber cotton can be used for adsorption. Thus, the ion adsorption capacity is greatly increased. Both the carbon fiber cotton and the charcoal fiber cotton can be directly bought on the market, ensuring that the cost is low.

Description

technical field [0001] The invention relates to a device for removing ions in water, in particular to an ion replacement treatment device for reducing liquid conductivity. Background technique [0002] The standard for industrial water stipulates that the conductivity of water should be less than 800us / cm, but in many cases, the conductivity of water does not meet the requirements. The conductivity of water is mainly affected by the ions in the water, which are mainly formed by the salts dissolved in the water. [0003] At present, technologies such as reverse osmosis and electrodialysis are generally used to reduce the conductivity of wastewater and remove salt. And other technologies have high requirements for pretreatment, and need to put a lot of chemicals, which will cause secondary pollution, and the investment of the project is also large. [0004] Another desalination method is electro-adsorption desalination. The research on electro-adsorption desalination in wate...

AI Technical Summary

Problems solved by technology

For this electrode, the contact area between carbon ions and the solution has increased, and the amount of ion adsorption has increased, but the cost has increased a lot.

[0006] see figure 1 , it can be seen that the existing electrodes for electrosorption realize the adsorption of ions by adhering carbon powder particles 101 on the conductor 100, and only the carbon powder particles located in the outermost layer of the conductor can play an adsorption role. Therefore, the amount of adsorbed ions cannot be very large.
