Description
Technical field
The invention belongs to air sterilization technique field, it is related to a kind of gasification process and device for producing sterilizing gas,
The method and device are particularly suitable for the disinfection by chlorine dioxide gas that gasifies.
Background technology
At present in the world in 41 kinds of Infectious Diseases, air-borne transmission has 14 kinds, accounts for various pathophorous first places.Disease
Pathogenic microorganism primary attachment on the dust particle of different-grain diameter, is suspended in air in the way of aerosol in atmosphere, is passed through
Respiratory tract enters human body, causes transmission of disease.From most dangerous chemical and biological weapons --- respiratory anthrax to newborn SARS,
The infectious diseases such as bird flu, can be by air borne, and these infectious diseases are once broken out, and will trigger serious consequence.Popular brain
Perimyelitis, mumps, viral pneumonia, influenza, common cold, acpuei pharyngitis, pulmonary tuberculosis, scarlet fever,
Legionaires' disease, pertussis, farmer lung, diphtheria, measles, smallpox, varicella etc. be also all by air borne and can by airborne,
Therefore, air sterillization is the prevention and control infection sources, prevents the important measures of cross-infection.Especially to personnel's Relatively centralized as
The public place of the larger space environment such as hospital, library carries out air prophylactic disinfection and terminal disinfection is particularly important,
Effective air sterillization can within a certain period of time kill the pathogenic microorganism being infected with airborne suspended particle, can be in prevention from suffering from the diseases
Played a key effect in control process.
Chlorine Dioxide Gas are particularly well-suited to due to its excellent high-efficiency broad spectrum bactericidal property and relatively low harmful by-products
To the sterilizing of large area environmental microorganism.Chlorine dioxide is one and is easy to the novel control that large area is used for air sterillization
System, Prevention Technique, in addition to the sterilizing of space environment microorganism is applied in field of public health such as hospital, libraries,
The sterilization of booth vegetable, fruit is also can be widely used to, to replace traditional agricultural chemical insecticide, the foodsafety of fruits and vegetables is improved,
Simultaneously in grain storage repository except mould mould proof, many fields such as preventing and treating of forest and crop diseases and pest also have extremely wide
Application prospect.
In addition, toxic and harmful is seriously polluted during Modern Residential and office space interior decoration cause indoor environment, gas
Body chlorine dioxide harmful substance such as aspect such as formaldehyde, methyl mercaptan, sulfide, phenol in air of degrading also has significant work(
Energy.
The large-scale air purification gasification device for being used for central air conditioner system in the prior art is more, and is used for the small model such as family
The device of confining space is less.The small-sized chlorine dioxide gas generating apparatus of in the market are mainly use chemical preparation principle, mostly
Number is reactive liquid solution or solid-liquid reaction, exists and produces the conversion ratio of chlorine dioxide low, is dispersed into the chlorine dioxide in air
The uneven problem of gas concentration height.
The content of the invention
It is an object of the invention to provide a kind of gasification process of air sterillization in space environment for relative closure, the party
Method can produce the air sterillization gas of high concentration, and disinfection efficiency is high, and the chlorine dioxide gas concentration being dispersed into air is equal
It is even.
It is a further object of the present invention to provide a kind of gasification installation of the use above method, the device volume is small, structure letter
It is single, it is adapted to family and Air Disinfection in Public Places is used, it is particularly suitable for the gasification of chlorine dioxide.
A kind of gasification process for air sterillization of the invention, comprises the following steps：
1）, chlorine dioxide matrix tablet and appropriate water be put into the closed reaction tank that several are sequentially communicated；
2）, be aerated to the first reaction tank using aeration pump；
3）, the mixed gas being made up of chlorine dioxide and a small amount of chlorine that generate previous reaction tank are used as aeration gas
Body, is passed through in the subsequent reactions pond of connection；
4）, last reaction tank, obtain chlorine dioxide with high purity sterilizing gas；
5）, by the branch pipe UNICOM of last reaction tank steam vent and air-spray pipe, to indoor conveying sterilizing gas.
The inventive method is to realize in several reaction tanks chlorine dioxide matrix medicament to react and produce high-purity two
Oxidation chlorine body, wherein realized first in the first reaction tank two kinds of tablets react to each other a large amount of chlorine dioxides of generation and
The mixed gas of a small amount of chlorine, the mixed gas of generation enter back into subsequent reactions pond, a small amount of chlorine are realized in subsequent reactions pond
The process of chlorine dioxide is further converted to, the gas for so generally producing is the chlorine dioxide of high-purity, so
All gas are quickly mixed by ejector with air afterwards, and being sprayed from gas outlet carries out the sky of space environment into space to be sterilized
Gas is sterilized and the sterilization of thing table.

Mouth 8 enters jet pipe 11, and is connected with jet pipe by bypassing air inlet 13, and jet pipe provides power by lower end centrifugal fan,
Produce wind speed air stream higher, air stream when by bypass air inlet, because of bypass air inlet and jet pipe angle at 45 °,
Slight negative pressure can be formed at bypass air inlet, along with the small malleation in small reaction tank, chlorine dioxide with high purity is in jet
Ejection after being rapidly mixed in pipe, it is to avoid the concentration of chlorine dioxide with high purity is too high in small reaction tank.
After terminating, feeding cover is opened, the waste liquid produced after reaction is outwelled, then pour into a small amount of running water cleaning two
It is secondary.
Aeration pump starts to be aerated chlorine dioxide matrix tablet and water, accelerates reaction, while stirring action is also functioned to,
The chlorine dioxide and air gas mixture that big reaction tank is produced enter chlorine dioxide matrix tablet in small reaction tank, with small reaction tank
Reacted, obtained chlorine dioxide with high purity, the power provided by centrifugal fan is quickly mixed by air-spray pipe 11 and air
Close, sprayed from gas vent, to avoid the phenomenon that sterilizing gas concentration is locally low or part is high, be finally reached fast reaction and obtained
Chlorine dioxide with high purity and space be discharged into after quickly mixing carry out disinfection sterilized purpose.
