Description
Technical field
This application involves disinfecting field, in particular to a kind of room temperature vaporizes disinfection system.
Background technique
Hydrogen peroxide (H2O2) used as disinfectant, there is lot of advantages, decomposition product is without any poison after killing bacterium
Harmful and stimulation water and oxygen, not will form secondary pollution, be a kind of more satisfactory sterile products.Especially peroxidating
Hydrogen has stronger killing bacterium ability compared with liquid in steam state, therefore carries out disinfection sterilizing increasingly using vapor phase hydrogen peroxide
It is in widespread attention, it has become pharmacopoeia of each country, pharmaceutical production quality management practices (GMP), disinfecting technical specification and is recommended
Method.
Vaporized hydrogen peroxide sterilization technology used at present and equipment 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 is added dropwise to about 130 DEG C of temperature or so makes its moment
2~6 microns of being vaporizated into of thimerosal particle, is reinjected into environment the sterilizing that carries out disinfection.It is mainly asked existing for this technology
Topic is: 1) needing to be vaporized under the high temperature conditions using the hydrogenperoxide steam generator (concentration is greater than 30%) of high concentration, so not
The evitable decomposition and corrosion problems for causing a large amount of hydrogen peroxide, 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 to control；3) convey hydrogen peroxide steam pipeline from
The outlet of generator starts all to have to be maintained at 60 DEG C or more up to the entire pipeline of diffusion tip, otherwise will be because of peroxidating
Hydrogen vapor (steam) temperature reduces and condensation occurs；4) very strict, general requirement is required the air humidity of disinfection sterilized space
RH is 40% or even 20% or less.Therefore this equipment be relatively suitble 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, medical instrument, bio-incubator etc., is not suitable for containing color steel plate and epoxy
The sterilization of the large spaces such as ground such as GMP dust proof workshop, hospital operating room etc..
In order to solve excessively 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) caused by resolution problem, patent CN101237894A and CN104984378A disclose a kind of ultrasonic atomization-separation skill
Art: disinfectant liquid atomization is recycled different big at a certain size particle (10-100 microns) first with ultrasonic atomization technique
The gravity of small atomizing particle is different, separates to different size of particle, recycles heating unit to little particle peroxidating
Hydrogen thimerosal carries out heating vaporization.Main problem existing for this technology is: 1) still needing to using high-strength hydrogen peroxide；2) it still needs to
It to use heating unit to carry out heating vaporization to little particle thimerosal, also be inevitable hydrogen peroxide steam mistake occur in this way
Thermal decomposition and condensation problem to the cold, 3) this method is only suitable for the thimerosal little particle (10-100 being atomized to ultrasonic atomization technique
Micron) it is vaporized, the particle for being not suitable for being atomized other atomization techniques is vaporized, therefore compatibility is undesirable.
The patent CN105597133A of applicant under one's name discloses atomization-isolation technics using venturi principle: first will
The Hydrogen Peroxide Disinfection Solution of low concentration (10% or less) is atomized into 10 microns of little particles below under the action of high speed hot wind, then
Size particles are separated according to the elasticity of different atomizing particles is different, recycle cavity structure to the little particle after separation
The method for carrying out separation of vaporization, obtains most of partial size in 1 micron of more little particle below.This method although do not need using
High-strength hydrogen peroxide, but there are the following problems: 1) there is still a need for using hot wind be vaporized；2) thimerosal after being atomized
Particle residence time in cavity structure is shorter, must use a plurality of cavities structure to reach preferable separation of vaporization effect,
It is thus bulky；3) particle for being not suitable for generating other atomization techniques is vaporized, and compatibility is also undesirable.
Therefore, lack one kind at present and disinfectant is suitably converted to a nanometer sterilization device for mist particle.
