Product Overview
The chlorate-process chlorine dioxide generator is a fully automatic on-site disinfection and oxidation device widely used in municipal drinking water, industrial wastewater, circulating water, pulp bleaching, and industrial sterilization. It uses sodium chlorate and hydrochloric acid as raw materials to produce high-purity chlorine dioxide under heating and negative pressure, featuring stable output, high conversion rate, and safe operation.
Chemical Reaction Principle
Heating reaction under negative pressure:
2NaClO₃ + 4HCl → 2ClO₂ + Cl₂ + 2H₂O + 2NaCl
