The method comprises: placing chlorine dioxide matrix tablets and a proper amount of water into a plurality of sequentially-communicated closed reaction pools; carrying out aeration on the first reaction pool by using an aeration pump; adopting the mixed gas comprising the chlorine dioxide gas generated in the previous reaction pool and a small amount of chlorine gas as the aeration gas, and introducing the aeration gas into the communicated subsequent reaction pool; and in the last reaction pool, obtaining the high-purity chlorine dioxide disinfection gas. With the method and the apparatus of the present invention, the high-concentration air disinfection gas can be generates, the disinfection efficiency is high, and the concentration of the chlorine dioxide gas released into the air is uniform.
Description
Technical field
The invention belongs to air sterilization technique field, relate to a kind of gasification process for the production of sterilizing gas and device, the method and device are particularly suitable for gasification disinfection by chlorine dioxide gas.
Background technology
At present in the world in 41 kinds of Infectious Diseases, air-borne transmission have 14 kinds, account for various pathophorous first place.On the dust particle of pathogenic microorganism primary attachment different-grain diameter in atmosphere, be suspended in air in aerocolloidal mode, enter human body by respiratory tract, cause transmission of disease.From the most dangerous chemical and biological weapons---respiratory anthrax is to the newborn infectious disease such as SARS, bird flu, and can pass through air borne, these infectious disease, once break out, will cause serious consequence.Epidemic cerebrospinal meningitis, mumps, viral pneumonia, influenza, common cold, acute pharyngitis, pulmonary tuberculosis, scarlet fever, legionnaires disease, pertussis, farmer lung, diphtheria, measles, variola, chickenpox etc. are also all by air borne with by airborne, therefore, air sterillization is the prevention and control sources of infection, prevents the important measures of cross infection.Especially air prophylactic disinfection is carried out to the public place as the larger space such as hospital, library environment of personnel's Relatively centralized and terminal disinfection seems particularly important, effective air sterillization can kill the pathogenic microorganism that airborne suspended particle is infected with within a certain period of time, can play a key effect in prevention and control of diseases process.
Chlorine Dioxide Gas, due to the high-efficiency broad spectrum bactericidal property of its excellence and lower harmful by-products, is specially adapted to the sterilizing to large area environmental microorganism.It is Novel control, a Prevention Technique being easy to large area and using that chlorine dioxide is used for air sterillization, except being applied to except the sterilizing of spatial environments microorganism at the field of public health such as hospital, library, also can be widely used in the sterilization of booth vegetable, fruit, to replace traditional agricultural chemical insecticide, improve the foodsafety of fruit and vegerable, simultaneously in grain storage repository except mould mildew-resistant, many fields such as the control of forest and crop diseases and pest also have extremely wide application prospect.
In addition, Modern Residential and office space interior decoration cause toxic and harmful in indoor environment seriously polluted, Chlorine Dioxide Gas degraded air in harmful substance as also having significant function in formaldehyde, methanthiol, sulfide, phenol etc.
Large-scale air purification gasification device for central air conditioner system in prior art is more, and less for the device in the space among a small circle such as family.Small-sized chlorine dioxide gas generating apparatus on market mainly adopts chemical preparation principle, great majority are reactive liquid solution or solid-liquid reaction, have that to produce the conversion ratio of chlorine dioxide low, be dispersed into the problem that chlorine dioxide gas concentration height in air is uneven.
Summary of the invention
The object of this invention is to provide a kind of gasification process for air sterillization in the spatial environments of relative closure, the method can produce the air sterillization gas of high concentration, and disinfection efficiency is high, and the chlorine dioxide gas concentration be dispersed in air is even.
Another object of the present invention is to provide a kind of gasification installation adopting said method, and this device volume is little, and structure is simple, is applicable to family and Air Disinfection in Public Places use, is particularly suitable for the gasification of chlorine dioxide.
A kind of gasification process for air sterillization of the present invention, comprises the steps:

Described second level gasification reactor apparatus is by little reaction tank 2, the second charge door 5 being arranged on little reaction tank 2 top, and the second exhaust port 8 and the second aeration tube 9 that are arranged on little reaction tank 2 sidewall form;
Described first row QI KOU 6 is connected with the second aeration tube 9 pipeline;
Described air-spray device is made up of centrifugal fan 12, Air pressurizer 14, air-spray pipe 11, bypass import 13, described air-spray pipe 11 is placed in vertical, centrifugal fan 12 is connected with air-spray pipe 11 by Air pressurizer 14, the bypass air inlet 13 of air-spray pipe 11 is communicated with the second exhaust port 8 of little reaction tank 2 device, be provided with gas outlet 10 in the front end of air-spray pipe 11, described gas outlet is arranged in casing.
The first described charge door 4 and the second charge door 5 have feeding cover to be used for sealing large and small reaction tank respectively.
During use, turn on the power switch, open feeding cover 4 and 5, according to interior space volume and required sterilizing gas concentration, add chlorine dioxide matrix tablet, then add a certain amount of water, cover feeding cover, aeration pump is started working, aeration pump one end connects air, sucks air and enters large reaction tank, start continually to carry out aeration to large reaction tank, stirring action is played to large reaction pool inner water and chlorine dioxide matrix tablet simultaneously, carry out fast reaction to make reacting greatly intracisternal material;
Because large reaction tank upper end feeding cover is airtight, the mist of the chlorine dioxide that chemical reaction produces and air enters little reaction tank through first row QI KOU 6, chlorine dioxide matrix tablet again in continual and little reaction tank reacts, the chlorine dioxide entered and the mist of air play aeration performance, agitating function equally in little reaction tank, fast reaction is carried out to make the mist of the chlorine dioxide matrix tablet in little reaction tank and large reaction tank reaction gained, obtain chlorine dioxide with high purity after little reaction tank chemical reaction, be sterilizing gas;
Same little reaction tank upper end feeding cover is airtight, the chlorine dioxide with high purity that reaction produces only has and enters jet pipe 11 through second exhaust port 8, and be connected with jet pipe by bypass air inlet 13, jet pipe provides power by lower end centrifugal fan, produce the air stream that wind speed is higher, air stream is through bypass air inlet, because of bypass air inlet and jet pipe angle at 45 °, at bypass air inlet, place can form slight negative pressure, add the small malleation in little reaction tank, chlorine dioxide with high purity sprays after being rapidly mixed in jet pipe, the concentration avoiding chlorine dioxide with high purity is too high in little reaction tank.
After use terminates, open feeding cover, the waste liquid produced after reaction is outwelled, then pour a small amount of tap water cleaning twice into.
Aeration pump starts to carry out aeration to chlorine dioxide matrix tablet and water, accelerated reaction, also play stirring action simultaneously, the chlorine dioxide that large reaction tank produces and air gas mixture enter little reaction tank, react with chlorine dioxide matrix tablet in little reaction tank, obtain chlorine dioxide with high purity, the power provided by centrifugal fan, by air-spray pipe 11 and air rapid mixing, spray from gas outlet, to avoid the phenomenon that sterilizing gas concentration local is low or local is high, finally reach fast reaction obtain chlorine dioxide with high purity and be discharged into after rapid mixing space carry out disinfection sterilization object.
