Abstract

Chlorine dioxide powder is prepared from a main agent and an activator, wherein the main agent is prepared from, in parts by mass, 1-2 parts of NaCl, 1-3 parts of CaCl2, 80-100 parts of NaClO2, 1-3 parts of Na2CO3 and/or 2-4 parts of NaHCO3; the activator is prepared from 25-35 parts of anhydrous citric acid and 1-6 parts of anhydrous sulfamic acid. In a production device of chlorine dioxide powder, the main agent and the activator can adopt solid products and have good dissolving property, and particularly, citric acid is taken as the activator, so that use, transportation and storage by a manufacture factory are very convenient.

Description

A kind of chlorine dioxide powder and preparation method
Technical field
The present invention relates to the side of a kind of preparation of disinfectant, especially chlorine dioxide powder and production chlorine dioxide powder Method.
Background technology
Chlorine dioxide starts substituted bleach powder carries out water process.At present, in worldwide, including about the 900 of the U.S. Individual place and the hundreds of place in Europe, chlorine dioxide is just being widely used as disinfectant and water treatment agent, is especially going up water most One water sterilization afterwards is processed.Oxidability is 2.6 times of oxygen, kills 7 times that microorganism ability is chlorine.
However, chlorine dioxide can over time be elapsed and changed, it prepares, preserves and analysis difficulty.As Formula 1 below～ Shown in 8, chlorine dioxide can be realized by the method for reducing chlorate in liquid acids such as sulfurous acid, hydrochloric acid or hydrogen peroxide Hundreds of ton of the daily output.But liquid chlorine dioxide content is low, the freight volume of material is big.
2NaClO3+H2SO3→2ClO2+Na2SO4+H2O [formula 1]
2NaClO3+4HCl→2ClO2+2NaCl+Cl2+2H2O [formula 2]
2NaClO3+H2O2+2HCl→2ClO2+2NaCl+O2+2H2O [formula 3]
5NaClO2+4HCl→4ClO2+5NaCl+2H2O [formula 4]
5NaClO2+2H2SO4→4ClO2+2Na2SO4+NaCl+2H2O [formula 5]
2NaClO2+NaClO+2HCl→2ClO2+3NaCl+H2O [formula 6]
2NaClO2+NaClO+H2SO4→2ClO2+Na2SO4+NaCl+H2O [formula 7]
2NaClO2+Cl2→2ClO2+ 2NaCl [formula 8]
Further, since chlorine dioxide is unstable at room temperature, thus chlorine dioxide should just using (when) before preparation, And the transport and packing of chlorine dioxide are not easy.When stored, chlorine dioxide is gradually decomposed into chlorous acid, chloric acid, chlorion Deng, and because with stronger oxidability, chlorine dioxide can be used as bactericide, i.e. last end production process of running water Disinfectant.The method for needing the more preferable formula and preparation of proposition chlorine dioxide preparation.Especially long shelf-life and storage are stable Pulvis prepares the formula of chlorine dioxide and preparation effect is more preferable.
CN 101970345 proposes a kind of pure two without chlorite (ClO2-), chlorate anions (ClO3-) and its salt The simple and easy method of oxidation chlorine water so that chlorine dioxide water may indeed act as such as food sterilization agent.Also propose for quantitative raw Produce the device of the pure chlorine dioxide without chlorous acid, chloric acid and its salt.A kind of titanium dioxide for quick production high concentration The chlorine dioxide of chlorine body and high concentration does not have the device of explosion potential.
The content of the invention
The present invention seeks to, propose that a kind of stable pulvis prepares the formula and preparation of chlorine dioxide, the stability of pulvis Can be good, it is difficult to react and volatilizees, the resting period, chlorine dioxide content was high, can reach 36%, is liquid system two up to more than 2 years 18 times of oxidation chlorinity.When being applied to prepare, at room temperature solubility is good high, and dissolubility is good.
The technical scheme is that, chlorine dioxide powder, including host and activator binary are constituted, the quality of host is matched somebody with somebody Side as follows, NaCl 1-2, CaCl2 1-3、NaClO2 80-100、Na2CO31-3 or and NaHCO32-4；
Activator is anhydrous citric acid 25--35, anhydrous sulfamic acid 1-6.
Or activator is technical hydrochloric acid 70-90 (30% concentration), anhydrous citric acid 3-10, anhydrous sulfamic acid 1-6.
Invention formulation prepares the device that the embodiment of chlorine dioxide is to provide production chlorine dioxide, described device bag Include：, there is chlorine dioxide wherein and produce reaction in the first and second reactive tanks；Host and activator are respectively by raw material supply unit Connect with the corresponding reactive tank, stirring and dissolving liquid after appropriate water generates chlorine dioxide.
Beneficial effect, according to the present invention, in chlorine dioxide generator, host and activator can be produced using solid Product, and solubility property is good, in particular by citric acid as activator, manufacturer uses shipping storage extremely convenient.Due to Selection powder product greatly improves environment as activator, improve safety coefficient, and maximum possible has prevented safety On hidden danger.Increased stabilizer, passivator.Reactant can produce chlorine dioxide by uniform stirring with high productivity.It is difficult anti- Should and volatilize, the resting period, chlorine dioxide content was high, can reach 36%, is liquid chlorine dioxide content up to more than 2 years 18 times.Powder product content is high, and small volume is easy to store and is transported, and what activator product was selected is solid agent product, is also fortune Defeated, storage is easy to use, on environment without impact, (alternative hydrochloric acid)；AB agent is separately transported and stored, and drastically increases peace Overall coefficient.Especially the effect of anhydrous citric acid is especially good, and cost does not increase how many.
Specific embodiment
Below, the preferred embodiments of the invention are described.However, the present invention can embody in different forms, should not It is considered as limited to listed embodiment herein.On the contrary, there is provided these embodiments can make disclosed content thoroughly and complete It is whole, and fully express the claimed scope of the present invention to those skilled in the art.
