Chlorine dioxide compound disinfectant generator and use method thereof

Abstract

The invention discloses a chlorine dioxide compound disinfectant generator and a use method thereof. In the generator, a second-level reactor is additionally arranged behind a first-level reactor; a gas-phase balance pipe communicated with a connection pipe is arranged between the first-level reactor and the second-level reactor; a heating water tank is arranged below the second-level reactor; sodium chlorate and concentrated hydrochloric acid are used as the raw materials in the generator to prepare the disinfectant by using the second-level reaction and first-level negative pressure aeration technology. The invention has the advantages of great production capacity, high reaction temperature, low production cost, high material use ratio, low equipment investment, and the like; and the obtained disinfectant can be directly used for sterilization in large-scale tap water plants and the sewage treatment plants, discoloration of chemical waste water and COD (Chemical Oxygen Demand) degradation treatment.

Description

technical field [0001] The invention relates to a chlorine dioxide composite disinfectant generator, in particular to a large-scale chemical method chlorine dioxide composite disinfectant generator and a use method thereof. Background technique [0002] Chlorine dioxide is a broad-spectrum bactericidal disinfectant, which can be widely used in the sterilization and disinfection treatment of drinking water, swimming pool water and hospital sewage; the sterilization and algae treatment of industrial circulating cooling water; the disinfection treatment of industrial cyanide-containing and phenol-containing wastewater ; Disinfection of food pipelines and preservation of fruits and vegetables. At present, for the sterilization and disinfection of large-scale waterworks; the sterilization, decolorization and deodorization treatment of urban sewage treatment plants; the degradation of COD and decolorization treatment of chemically polluted wastewater, etc., my country mainly relie...

AI Technical Summary

Problems solved by technology

Due to the poor thermal conductivity of PVC, the reaction temperature of the reactor can only reach 50-55°C, which is quite different from the optimum reaction temperature of 70-80°C, so the raw materials are not completely reacted in the generator, and the utilization of raw materials The rate is low, and it is a small chlorine dioxide generator

Most of the existing single-stage or multi-stage chlorine dioxide generators operate in winter because cold air aeration enters the reactor to greatly reduce the reaction temperature, and most multi-stage chlorine dioxide generators are multi-stage aeration, which greatly reduces the chlorine dioxide Sodium acid conversion rate
