An electrolytic chlorine dioxide compound disinfectant generator

Abstract

The utility model relates to an electrolytic chlorine dioxide compound disinfectant generator. It includes a saltizer, an automatic softener, a precision filter, a tank-type electrolytic cell composed of an anode and a cathode, a cooling water inlet, a concentrated brine inlet, and a chlorine dioxide compound disinfectant outlet; Surface bipolar structure, an intermediate electrode is installed between the anode and the cathode, a PTF mesh diaphragm is installed between the anode and the intermediate electrode, and a PTFE microporous permeable electrolytic diaphragm is installed between the intermediate electrode and the cathode. The invention has the characteristics of extremely high electrical conductivity and extremely corrosion resistance, and the efficiency of producing ClO2 is greatly improved; its current efficiency is greater than 95%, and the salt utilization rate is above 95%; the content of ClO2 is increased to more than 35%, and chlorine and other disinfectant gases It accounts for 65%, which greatly improves the disinfection and oxidation effect and reduces the operating cost.

Description

Technical field [0001] The invention relates to a sterilization, disinfection, algae elimination, decolorization, deodorization, and COD reduction widely used in the food industry, daily chemical industry, pharmaceutical industry, and various industrial sewage, industrial circulating water, drinking water, hospital sewage, and domestic sewage , BOD index and electrolytic chlorine dioxide compound disinfectant generator for papermaking and textile industry bleaching. Background technique [0002] CN200420069271.4 discloses the company’s chlorine dioxide composite disinfectant generator, which includes a concentrated salt water inlet, a filter, a softener, an electrolytic cell composed of an anode and a cathode, a cooling water inlet and outlet, and a liquid discharge port. A quartz microporous permeable membrane is arranged between the cathodes. The structure of the electrolytic cell is single-sided and unipolar, and a quartz diaphragm is used between the anode and the cathode. ...

AI Technical Summary

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%
