Problems solved by technology

[0003] The disadvantages of this structure are: (1) there are only anode and cathode and there is a quartz microporous permeable membrane between them; the conductivity and micropore diameter of this structure are still not ideal; cause salt consumption, power consumption, and produce ClO 2 The efficiency is also not ideal; (2) the extremely corrosion resistance of the quartz diaphragm is not ideal, resulting in a not too long service life of the anode, sometimes fouling, and a high failure rate
(3) The cooling water inlet and outlet are set in the anode central tube, resulting in unsatisfactory cooling effect and difficult temperature control
Due to the limitations of the electrolyzer structural form described in CN200420069271.4 caused ClO 2 Low concentration, ClO 2 The concentration is only 8-12%
