Description
Technical field
This utility model is related to a kind of preparation facilitiess of chlorine dioxide, and more particularly to one kind is prepared high-purity using low acid amount
Degree, the special purpose device of high activity chlorine dioxide.
Background technology
Chlorine dioxide is socially widely used as the wide spectrum powerful disinfectant of new generation that generally acknowledges in the world
In fields such as drinking water disinfection, industrial circulating water and various wastewater treatments.As chlorine dioxide antiseptic is rapid, oxidability strong,
Effect is good, noresidue, have no side effect, so, currently pay much attention under the situation of environmental conservation in country and governments at all levels, also
People are arrived more and more to approve, have been optimal cleaning and sterilizing agent at present.
Chlorine dioxide generator history existing nearly more than 20 years at home is prepared, is mixing chlorine dioxide generator earliest
First develop, also develop high-pure chlorinedioxide generator afterwards, up till now, different generators have very in every respect
Big progress, its industry size have also obtained constantly developing, and play an important role in water process and field of Environment Protection, especially
It is many advantages that high-pure chlorinedioxide generator can fully show chlorine dioxide, so, commercially enjoy favor.Mesh
The generator of high-pure chlorinedioxide is prepared from research and development using sodium chlorate in front China market, be all substantially around R11 methods (i.e.
Ternary method) process is researched and developed, but application practice finds, although ternary method preparation method refers in purity, conversion ratio
Put on and do not have larger problem, but consumption sulfuric acid amount is very big, do not only result in preparation cost height, and waste liquid amount is very big after reacting, waste liquid
Acid content also high, the body that can feed water in the application brings some other impurity, particularly to Drinking Water, can bring some not
Profit affects；In terms of to Industrial Wastewater Treatment, significantly improving for cost for wastewater treatment is will also result in；Due to also not having in the market
There is more preferably strong oxidizer replacing chlorine dioxide, therefore, above-mentioned condition is difficult to change.Research and develop so for many years in China,
The never successfully original research and development of high-purity generator, are nearly all around ternary method, and carry out three kinds of raw materials with this and match somebody with somebody
Researched and developed than the change of, structure of reactor or material, technique and composition of raw materials are all without basic change.Grind in how many years
Study carefully proof, reduce acid amount on ternary method Process ba- sis, cannot realize, only adopt new process and match somebody with somebody and just now may be used

Sulfuric acid concentration is improved, if these conditions are applied on the generator, and is prepared on the basis of former ternary method process, meeting
Cause that reacted acutely to carry out, be also easy to produce detonation or blast, reaction normally, stably cannot be carried out；
If 2. improving sulfuric acid concentration, high-concentration sulfuric acid can produce the substantial amounts of heat of dilution in reactor, if the heat of dilution is flat
Do not weigh, easily produce detonation or blast yet, make equipment cannot normally, stable operation；
3. as ternary method (R11 methods) is vanguard technology method generally acknowledged in the world, extensive in production practices
Using, before new method is produced, the general category for being difficult to jump out this technology；According to the mechanism of production of chlorine dioxide, dioxy
Changing chlorine and generation being reacted only under certain acidity, especially with sodium chlorate method, acidity requirements are also higher；So, drop
Low sour amount prepares high-pure chlorinedioxide and is accomplished by researching and developing new process and technical recipe to solve, and not only there is very disaster
Degree, and be to need certain human and material resources and time enough.
Currently, with the great attention that Environmental is protected, high-purity chlorine dioxide gas generator is to many water bodys
Sterilization, sterilization, oxidation, particularly to suffering from certain city in terms of the process containing cyanogen and containing the particular/special requirement water body such as heavy metal
Field demand, this are that mixing chlorine dioxide generator is beyond power.Therefore, the research and development of low acid system and special purpose device have been compeled in eyebrow
Eyelash.
