Problems solved by technology

[0003] The disadvantages of this structure are: (1) There are only anode and cathode and there is a quartz microporous membrane between them; the conductivity and micropore size of this structure are still not ideal; resulting in salt consumption, power consumption, and ClO2 production The efficiency is not ideal; (2) The extreme corrosion resistance of the quartz diaphragm is not ideal, resulting in a short 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%

Abstract

The invention discloses a chlorine dioxide composite disinfectant generator employing an electrolytic process. The chlorine dioxide composite disinfectant generator comprises a salt dissolver, an automatic softening machine, a precise filter, a slot-type electrolyzer composed of an anode and a cathode, a cooling water inlet, a strong brine inlet, and a chlorine dioxide compound disinfectant outlet. The chlorine dioxide composite disinfectant generator is characterized in that the electrolyzer is of a double-sided bipolar structure; a middle electrode is filled between the anode and the cathode; a PTF mesh diaphragm is arranged between the anode and the middle electrode; and a PTFE (polytetrafluoroethylene) microporous osmotic electrolysis membrane is arranged between the middle electrode and the cathode. The chlorine dioxide composite disinfectant generator has the characteristics of high electric conductivity and corrosion resistance; the efficiency of producing ClO2 is greatly improved; the current efficiency is greater than 95%; the salt utilization rate is over 95%; the ClO2 content is improved to over 35%; chlorine and other antiseptic gas are 65%; and the sterilization and oxidization effects are greatly improved, and the operating cost is reduced.
