X; zl201210016704.9; zl201410197346.5; zl 201410760013.9) describes an electrodeionization technique (Membrane-free Electrodeionization, MFEDI for short) without ion exchange membranes. In principle, the MFEDI device is equivalent to a mixed ion exchange bed which replaces the traditional chemical regeneration by the electric regeneration, is commonly called as an electric mixed bed, has the advantages of investment saving, low operation cost, environment protection, simple operation and maintenance, small occupied area and the like, can replace the traditional mixed bed and the conventional electric deionization technology, and is widely applied to high purity water treatment.
The MFEDI device needs to be filled with ion exchange resin, and in order to prevent the outflow of the resin, the technical measures adopted in the above-mentioned patent document of the authorized invention are as follows: a mesh electrode with a pore size smaller than the particle size of the ion exchange resin particles is adopted; or a netlike electrode with the pore size larger than the particle size of the ion exchange resin particles is adopted, but 1-2 layers of filter screens or filter cloth with the pore size smaller than the particle size of the ion exchange resin particles are added at the outer side of the electrode; or a netlike electrode with a pore size larger than the particle size of the ion exchange resin particles is adopted, but a water filtering cap is arranged outside the electrode.
The above measures can effectively intercept the ion exchange resin, but have some obvious defects in practical application. When using a screen or filter cloth, the main problem faced is that these materials often lack sufficient mechanical strength, are easily damaged during use, and may cause resin leakage in severe cases.
In addition, these materials lack sufficient rigidity to be easily secured to the porous plate of the MFEDI device, and there is often a large gap between the edge of the porous plate and the porous plate, and the necessary sealing measures are required, which is quite complicated to install.
When the water filtering cap is used, although the above problems can be solved, the uniformity of water supply is poor, and adverse effects are generated on both water purification and electric regeneration of the failed resin.
