Chlorine dioxide generator
Product overview
ClO2 chlorine dioxide is one of the few compounds in nature completely or almost completely to the monomer free radicals form existence, room temperature is yellow green or orange red gas, ClO2 vapor in appearance and taste similar to chlorine, a choking odor; although the electron distribution of ClO2 was not saturated (paramagnetic), but no two poly or poly ClO2 tendency, soluble in water, forming a solution of yellow green dissolved in aqueous solution, ClO2 molecular volume exists, is advantageous in the water diffusion. The explosion concentrated vapor ClO2 over atmospheric pressure 41kPa, the explosion at 40kPa pressure; when the ClO2 concentration is higher than 10% (Wt/V) or in the air is greater than 10% (V/V), prone to low levels of explosion, in the presence of organic vapors, the explosion may become strong. Any attempt to compress or store chlorine dioxide, either alone or in combination with other gases, has not been commercially successful. Because of its explosive hazard, chlorine dioxide must be manufactured at the place of use. It should be noted that the gas ClO2 with air diluted to 10% (V/V) below the concentration of relatively safe, ClO2 aqueous solution concentration of less than about 8~10g/L, will not produce enough to cause the explosion of high pressure steam. In the practice of water treatment, the concentration of ClO2 is less than 4g/L, and the treatment level is generally in the range of 0.1 to 5.0mg/L.
Two, product features
ClO2 aqueous solution is very stable if kept in a cool place, tightly sealed and light free. The chlorine dioxide solution is slightly acidified (pH=6), that is, the stability is enhanced by inhibiting its disproportionation. The aqueous solution of ClO2 UV absorption spectrum with a wide, there is an absorption peak at 360nm, molar absorption coefficient is 1230L/ (mol/nm). UV absorption spectroscopy has been used to analyze the presence of chlorine dioxide in the presence of a mixture of chlorine or other oxides. Continuous iodine and amperometric titrations are also used to measure the presence of chlorine dioxide in the presence or absence of chlorine oxides. Chlorine dioxide disinfection has excellent performance.
As a new type of oxidant and disinfectant, chlorine dioxide with its efficient, broad-spectrum, no residue, no by-products of disinfection and deodorization, decolorization and deodorization strong oxidation ability, has become a leader in the field of water treatment. And ultraviolet, ozone, sodium hypochlorite, chlorine and other traditional disinfectant than chlorine dioxide has a unique advantage, it is increasingly becoming the first choice of the industry.
