Description
Technical field
This utility model relates to laboratory disinfect in situ bactericidal unit, particularly a kind of hydrogen peroxide gas (VHPS) disinfect in situ bactericidal unit.
Background technology
China standard GB19489-2008 " laboratory bio-safety General Requirement " requirement, to the laboratory of BSL-3 level or higher biological safety protection level, its room air can only be discharged by high efficiency particle air filter, and requires air draft high efficiency particle air filter to carry out disinfect in situ sterilizing.
The at present sterilization to laboratory building thing air and surface, using more is to adopt paraformaldehyde gas fumigation.But formaldehyde is classified as suspect carcinogen matter by WHO, to environment and personnel health's potential hazard, it uses and has been subject to increasing restriction.On the other hand, synchronize with air draft high efficiency particle air filter at laboratory while sterilization, naturally the diffusion of sterilizing gas in room, only in the time that row is residual, the filter paper wrinkle surface of sterilizing gas low concentration, of short duration contact high efficiency particle air filter (HEPA), the microorganism that is difficult to air draft high efficiency particle air filter surface to be held back is effectively sterilized.
Summary of the invention
This utility model, for the halfway shortcoming of prior art sterilizing, provides a kind of novel hydrogen peroxide gas disinfect in situ bactericidal unit with higher disinfecting/sterilizing efficiency.
For achieving the above object, this utility model can be taked following technical proposals:
Hydrogen peroxide gas disinfect in situ bactericidal unit, comprise high efficiency particle air filter, the first high efficiency particulate air filter, the second high efficiency particulate air filter, catalytic destroyer, dehumidifier, preheater and carburator, high efficiency particle air filter is connected with the first high efficiency particulate air filter, the first high efficiency particulate air filter is connected with catalytic destroyer, catalytic destroyer is connected with dehumidifier, dehumidifier is connected with the second high efficiency particulate air filter, the second high efficiency particulate air filter is connected with preheater, preheater and carburator, carburator is connected with high efficiency particle air filter.
As preferably, also comprise the hydrogen peroxide holding vessel being connected with carburator.
As preferably, between high efficiency particle air filter and the first high efficiency particulate air filter, use standard type DN32 fast-assembling interface to be connected between high efficiency particle air filter and carburator.
This utility model, owing to having adopted above technical scheme, has significant technique effect:
Disinfection is thorough, does not have sterilization dead angle, can thoroughly kill the microorganism such as antibacterial of high efficiency particle air filter remained on surface.
Use hydrogen peroxide to sterilize as the substitute of formaldehyde, can greatly reduce the potential injury that formaldehyde brings environment and operator's health.
Simple for structure, can meet the disinfection demand of various types of laboratorys or Biohazard Safety Equipment, can meet the bio-safety standard-required of the said equipment simultaneously, simple to operate, germicidal efficiency is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of the hydrogen peroxide gas disinfect in situ bactericidal unit described in embodiment 1.
The specific embodiment
Below in conjunction with embodiment, this utility model is described in further detail.
Embodiment 1
Hydrogen peroxide gas disinfect in situ bactericidal unit, as shown in Figure 1, comprise high efficiency particle air filter 1, the first high efficiency particulate air filter 2, the second high efficiency particulate air filter 3, catalytic destroyer 4, dehumidifier 5, preheater 6 and carburator 7, high efficiency particle air filter 1 is connected with the first high efficiency particulate air filter 2, the first high efficiency particulate air filter 2 is connected with catalytic destroyer 4, catalytic destroyer 4 is connected with dehumidifier 5, dehumidifier 5 is connected with the second high efficiency particulate air filter 3, the second high efficiency particulate air filter 3 is connected with preheater 6, preheater 6 and carburator 7, carburator 7 is connected with high efficiency particle air filter 1.Between high efficiency particle air filter 1, the first high efficiency particulate air filter 2, the second high efficiency particulate air filter 3, catalytic destroyer 4, dehumidifier 5, preheater 6 and carburator 7, form the loop of sterilization, gas in high efficiency particle air filter 1 after sterilization is after the first high efficiency particulate air filter 2, enter catalytic destroyer 4 and carry out catalytic decomposition, dehumidify by dehumidifier 5, the relative humidity of gas is reduced to the VHP needed humidity of sterilizing.Gas after dehumidifying is through the second high efficiency particulate air filter 3, and in preheater 6, carries out preheating, sneaks into hydrogen peroxide gas and reach after the concentration of expection in carburator 7, again enters high efficiency particle air filter 1, realizes the object of the sterilization that moves in circles.
In addition, hydrogen peroxide gas disinfect in situ bactericidal unit also comprises the hydrogen peroxide holding vessel 8 being connected with carburator 7, for the hydrogen peroxide source of carburator 7 is provided.
Between high efficiency particle air filter 1 and the first high efficiency particulate air filter 2, use standard type DN32 fast-assembling interface to be connected between high efficiency particle air filter 1 and carburator 7, be easy to dismounting, it is convenient to change, and is convenient to the Fast Installation to hydrogen peroxide gas disinfect in situ bactericidal unit.
In a word, the foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to this utility model claim change and modify, and all should belong to the covering scope of this utility model patent.
