Chlorine dioxide generator

Abstract

The invention relates to the technical field of generators, in particular to a chlorine dioxide generator. The chlorine dioxide generator comprises a reaction utensil, a sodium chlorite storage tank,an activating agent solution storage tank, a heating water tank, an electrolytic bath and a high-pressure reaction bladder-like inner container, wherein the sodium chlorite storage tank and the activating agent solution storage tank are respectively arranged on the left side and the right side of the top end of the reaction utensil; a sodium chlorite flowmeter and an activating agent flowmeter arerespectively arranged at the upper ends of the sodium chlorite storage tank and the activating agent solution storage tank; two pipelines are arranged on the outer sides of the sodium chlorite storage tank and the activating agent solution storage tank; the pipelines penetrate through a self-sucking pump and the reaction utensil to enter into the electrolytic bath; a cathode chamber and an anodechamber are respectively arranged on the left side and the right side of the electrolytic bath; a cathode liquid drainage hole and an anode liquid drainage hole are respectively formed in the lower side of the cathode chamber and the anode chamber; the cathode chamber is completely separated from the air in an electrolysis process when chlorine dioxide is produced through reaction in the electrolytic bath at the same time; and an explosive danger on the produced hydrogen is avoided, so that the security is greatly improved.

Description

technical field [0001] The invention relates to the technical field of generators, in particular to a chlorine dioxide generator. Background technique [0002] As a strong oxidizing agent, chlorine dioxide has a wide range of applications. It can be used as a safe, broad-spectrum, and efficient disinfectant for drinking water disinfection, sterilization of circulating cooling water, urban domestic sewage and reclaimed water reuse. Engineering disinfection, hospital sewage disinfection, swimming pool water disinfection, etc. can also be used in organic wastewater, printing and dyeing, deodorization and other wastewater purification treatment. Chlorine dioxide can undergo redox reactions with many organic and inorganic compounds to remove algae, Cyanide-breaking treatment of cyanide-containing wastewater, removal of phenolic compounds, sulfide, organic sulfur odor control, etc., can also be used as an excellent bleaching agent, which replaces chlorine to bleach pulp.

AI Technical Summary

Problems solved by technology

[0003] The working principle of the chemical method chlorine dioxide generator is to mix sodium chlorate and hydrochloric acid solution to produce a mixed gas of chlorine dioxide and chlorine gas. At present, the commonly used reactors are mostly one-stage fully mixed reactors. In the preparation of chlorine, the chemical reaction is an endothermic reaction. The temperature of the existing chlorine dioxide generator often drops in the middle and late stages of the reaction, resulting in a decrease in the conversion rate of raw materials and a decrease in the amount of chlorine dioxide produced. Although some A heating device has been added to the generator, but real-time detection cannot be achieved, and the purpose of heating according to needs to improve the conversion rate of raw materials is, therefore, the reaction efficiency of the existing chlorine dioxide generator is low, and improvement is urgently needed to improve the conversion rate of raw materials. In addition, the existing chlorine dioxide generators are easily corroded after being used for a period of time, and the service life is generally relatively short, which increases the cost of use. Therefore, a chlorine dioxide generator is needed to improve the above problems
