Description
Technical field
The present invention relates to a kind of disinfectant method, relate in particular to and a kind of thereby highly purified chlorine dioxide regularly, quantitatively is sent to the method for killing airborne various pathogenic bacterias in the air, the invention still further relates to the special equipment of realizing said method, belong to technical field of inorganic chemical industry.
Background technology
Chlorine dioxide is wide spectrum powerful disinfectant of new generation, high-efficient oxidant and the high-quality bleach of generally acknowledging in the world, classified as the agent of AI level efficiently and safely disinfecting by World Health Organization (WHO), can be widely used in fields such as drinking water disinfection, sewage disposal.Because chlorine dioxide antiseptic is rapid, effective, noresidue has no side effect, so, more and more obtain people's approval.In recent years, along with the enhancing of people to environmental protection consciousness and health perception, the hope that the employing chlorine dioxide carries out air sterillization is also strong gradually.
In China, adopt the method for air sterillization a lot of for a long time, as chlorine, ozone, ultraviolet light, photocatalyst, peracetic acid, formaldehyde or the like, but because these traditional sterilization methods, what have is effective, but cost is higher, uses inconvenience; The cost that has is low, but bactericidal effect is poor, and has residually, and particularly liquid disinfectant can only adopt sprinkling, method such as stifling, is difficult to realize control, and effect is not very good.Along with the gradually understanding of people to chlorine dioxide, also had in recent years and begin to adopt chlorine dioxide to carry out air sterillization, wherein, have and adopt chlorine dioxide generator, because gas purity is not high, be difficult to regularly, quantitatively control, the unsafe problems that preparation process easily produces can't be avoided, and therefore is difficult to apply in the air sterillization field.Also have and adopt stable ClO 2 solution, but, using method also only rests on sprinkling, spraying or naturally on the method such as volatilization, because uniformity coefficient is poor, atomizing effect is bad, not only influences bactericidal effect, and to around article easily pollute or corrode, easily stimulate people's eyes and respiratory system, have certain safety problem, promote the use of and be subjected to certain limitation.
For adopting stable ClO 2 solution to carry out air sterillization as primary raw material, the subject matter that exists is the same with traditional sterilizing method at present, be that method is simple, efficient is low, use inconvenience, most importantly can not regularly, quantitatively, carry out air sterillization, lack of homogeneity with deciding concentration, do not satisfy the sterilization of various places, disinfectant quality requirement, control the improper unsafe factor that also easily causes.So far, also there is not a kind of chlorine dioxide that utilizes to carry out safety, control sterilization effectively, disinfectant air disinfection method and equipment at home.
Summary of the invention
One of purpose of the present invention provides a kind of chlorine dioxide that utilizes air is carried out safety, the method for sterilizing effectively.

The objective of the invention is to be achieved through the following technical solutions:
A kind of chlorine dioxide that utilizes carries out safety, the method for sterilizing effectively to air, comprising:
With sodium chlorite (NaClO
2) solution and dilute hydrochloric acid join in the gasifier and react, simultaneously, constantly compressed air delivery is advanced in the gasifier, made the reaction gasification, produce high-purity chlorine dioxide gas and take it out of gasifier by the compressed air of being introduced, draining into needs the disinfectant space that air is carried out disinfection.
In order to reach better technique effect, preferred, with concentration 1.8～2.5% sodium chlorite (NaClO
2) solution and concentration be 4～6% dilute hydrochloric acid according to mol ratio is that 1: 3.5～4.4 ratio joins in the gasifier and reacts; Wherein, the temperature of reaction is preferably 15～35 ℃.
In gasifier, by volume calculate, preferably gas liquid ratio is controlled to be 16.7～23.3: 1;
In the said method, a conduit can be set in the bottom of gasifier, the liquid phase part of gasifier can be discharged from gasifier by this conduit.
The present invention is disinfectant with sodium chlorite solution, and hydrochloric acid is activator, adopts the positive pressure gas micronizing technology, at a certain temperature, control certain gas liquid ratio, stable ClO 2 solution is fully reacted in gasifier, gasifying chlorine dioxide, and its reaction principle is as follows:
5NaClO
2+4HCl＝4ClO
2↑+5NaCl+2H
2O
The inventive method is at first prepared highly purified chlorine dioxide (purity is greater than 99%), need the disinfectant space to carry out air sterillization the highly purified chlorine dioxide timing that will be produced, quantitative being transported to, can reach best bactericidal effect, solve air sterillization and problem of environmental pollution to greatest extent, effectively prevent and stop the aerial propagation of pathogenic bacteria.
