Description

A kind of room temperature vaporizes disinfection system
Technical field
The application is related to disinfecting field, more particularly to a kind of room temperature vaporization disinfection system.
Background technology
Hydrogen peroxide (H2O2) used as disinfectant, with lot of advantages, catabolite is without any poison after killing bacterium The water and oxygen of evil and stimulation, will not form secondary pollution, be a kind of more satisfactory sterile products.Particularly peroxidating Hydrogen has stronger killing bacterium ability in steam state compared with liquid, therefore carries out disinfection sterilizing increasingly using vapor phase hydrogen peroxide It is in widespread attention, recommended as pharmacopoeia of each country, GMP (GMP), disinfecting technical specification Method.
The vaporized hydrogen peroxide sterilization technology and equipment for being used at present mainly still utilize flash evaporation technology:I.e. first will be highly concentrated The high temp objects surface that the hydrogenperoxide steam generator (concentration is generally higher than 30%) of degree drops to about 130 DEG C or so of temperature makes its moment The thimerosal particle of 2~6 microns of being vaporizated into, is reinjected into the sterilizing that carries out disinfection in environment.What this technology was present mainly asks Topic is：1) hydrogenperoxide steam generator (concentration is more than 30%) of high concentration is needed to use to be vaporized under the high temperature conditions, so not The evitable decomposition for causing a large amount of hydrogen peroxide and corrosion problems, thus material compatibility is poor；2) this technology and Equipment is directed to different room-sizes, and the concentration parameter of hydrogen peroxide is difficult control；3) conveying hydrogen peroxide steam pipeline from The outlet of generator starts all to have to be maintained at more than 60 DEG C up to the whole pipeline of diffusion tip, otherwise will be because of peroxidating Hydrogen vapor (steam) temperature is reduced and condensation occurs；4) the air humidity requirement to sterilized space of sterilizing is very strict, general to require RH is 40% or even less than 20%.Therefore this equipment be relatively adapted to it is small-sized it is corrosion-resistant can confined space for example transferring cabin, isolator, The sterilization of freeze dryer, Biohazard Safety Equipment, medicine equipment, bio-incubator etc., is not suitable for containing color steel and epoxy The sterilization of the large spaces such as ground such as GMP dust proof workshops, hospital operating room etc..
In order to solve too high (the 130 degree of left sides of existing vaporized hydrogen peroxide flash evaporation technology particle excessive (2-6 microns) and temperature It is right) resolution problem that causes, patent CN101237894A and CN104984378A disclose a kind of ultrasonic atomization-separation skill Art：First with ultrasonic atomization technique by disinfectant liquid atomization into a certain size particle (10-100 microns), recycle different big The gravity of small atomizing particle is different, and different size of particle is separated, and recycles heating unit to little particle peroxidating Hydrogen thimerosal carries out heating vaporization.The subject matter that this technology is present is：1) still need to use high-strength hydrogen peroxide；2) still need to Heating vaporization is carried out to little particle thimerosal using heating unit, so or inevitably hydrogen peroxide steam mistake occur Thermal decomposition and condensation problem, 3 to the cold) the method thimerosal little particle (10-100 for being only suitable for ultrasonic atomization technique atomization Micron) it is vaporized, be not suitable for being vaporized the particle of other atomization techniques atomization, therefore compatibility is undesirable.
Applicant patent CN105597133A under one's name is disclosed using the atomization-isolation technics of venturi principle：First will The Hydrogen Peroxide Disinfection Solution of low concentration (less than 10%) is atomized into less than 10 microns of little particle in the presence of high speed hot blast, then Elasticity difference according to different atomizing particles is separated to size particles, recycles cavity structure to the little particle after separation The method for carrying out separation of vaporization, obtains more little particle of most of particle diameter below 1 micron.Although this method need not be used High-strength hydrogen peroxide, but there are the following problems：1) there is still a need for being vaporized using hot blast；2) thimerosal after being atomized Particle residence time in cavity structure is shorter, want to reach preferable separation of vaporization effect must using multiple cavity structures, It is thus bulky；3) be not suitable for being vaporized the particle that other atomization techniques are produced, compatibility is also undesirable.

Door and window has first been closed in each laboratory before sterilization, and air sampling is made (sampled point away from ground 1m, by 5 with sedimentation Individual plate is put in surrounding at the 20cm of corner and center respectively, exposes 15 minutes), as control before sterilization.Then it is content 6%Active Hydrogen Peroxide Disinfectant presses 5ml/m3Dosage is injected in each atomizer 12, and each laboratory is entered respectively Row even spraying.Atomization terminate after by closed 1 hour of laboratory, by same method before sterilization, carry out disinfection post-sampling.Will sampling Flat board puts 35 DEG C of incubators, cultivates 24h, counts clump count in plate, calculates killing rate.
3. experimental result
Result of the test (being shown in Table 2) shows, uses electric centrifugal sprayer active Hydrogen Peroxide Disinfectant of spraying to act on 1 Hour, be only about 10% to the average elimination factor of natural bacteria in Laboratory Air (average colony number is 54 in plate before sterilization, It is 49 after sterilization).Acted on 1 hour with the active Hydrogen Peroxide Disinfectant of medicine aerosol generator spraying, to experiment Interior Space The average elimination factor of natural bacteria is about 80% (average colony number 56 in plate, is 12 after sterilization before sterilization) in gas.But work as and match somebody with somebody After closing the room temperature vaporization disinfection system use that this technology is provided, two kinds of atomizers 12 are flat to natural bacteria in Laboratory Air Equal elimination factor has reached 100%.
Disinfection Effect compares before and after the vaporization of table 2 is separated
The above, is only several embodiments of the application, any type of limitation is not done to the application, although this Shen Please disclosed as above with preferred embodiment, but and be not used to limit the application, any those skilled in the art are not taking off In the range of technical scheme, make a little variation using the technology contents of the disclosure above or modification is equal to Effect case study on implementation, belongs in the range of technical scheme.
