Abstract
The present invention relates to an improved method, an improved process and improved equipment for disinfecting and sterilizing all types of surfaces, indoor air and side-room air contaminated by microorganisms, wherein the improved equipment comprises a multi-wavelength narrow-spectral width UV source, and provides good effects in damage on viruses, bacteria, the DNA of spores and cysts, and shells or membranes compared to the mercury-based 254 nm sterilizing lamp.
Description
The application is filing date on January 29th, 2009, Application No. is the 200980155935.4th, invention entitled " is used for
The divisional application of the Chinese patent application of the method and apparatus of the improvement of generation high level disinfection effect in air and surface ".
Technical field
Present invention teaches for air, all types of surface and food are carried out except microbial decontamination and sterilizing change
Kind method and apparatus.Described method utilizes the multi-wavelength UV photon being combined with remote UV photon and the effect of UV-C photon, thus
Produce higher than be used alone arbitrary source and the disinfective action of issuable disinfective action level.Described equipment is by phase
Two room compositions separately of different wave length are produced during with excitation process.
Background technology
It is based primarily upon use commercially available sterilization ultraviolet (GUV) for the sterilizing of air and all prior aries of sterilization
Lamp.These lamps are pulse excitation or continuous agitation.Continuous lamp is based on mercury, and mainly launches at 254nm.Have at present
A lot of companies produce the equipment based on GUV light for destroying virus in room air, bacterium, spore and pathogen.Because
It makes Interior Space air-flow Ricoh of the place of being constantly exposed to and has enough process open-assembly times in time in the past, therefore has
The process of effect.Required open-assembly time, this depended on different microorganisms under 254nm in the range of extremely hundreds of seconds tens of seconds
Light absorpting ability.Although the room air in this independent room for process is effective, but for process quickly through big pipeline
Large volume moving air impracticable.The needing of its long process time makes it in processing most of surface and impracticable.
According to its not same-action to biosystem, wide UV spectrum is divided into four regions.Doctor about these regions
Technics mainly has：UV-A, its scope being defined as 320nm to 400nm or wave band；UV-B, it is defined as 280nm to 320nm
Wave band；And UV-C, it is defined as comprising the wavelength less than 280nm.At present, UV-C wave band be further divided into by 185 to
Two parts of the UV-C composition of the remote UV (FUV) of 250nm and 250 to 290nm.Because the absorption spectrum of chemical bond is wider than these
The wave band of justice definition is much narrower, and therefore photochemical scholar and photobiologist typically do not use these terms.As an alternative, it uses
The wavelength of the radiation applied is to be associated with viewed effect.
Advocate that UV-C (GUV) radiation using sterilization makes DNA inactivate.This is because mercury lamp is close in the transmitting of 254nm
In good DNA absorption bands.Not yet advocate to be combined to produce higher levels of microorganism deactivated by the UV photon of different wave length.
Additionally, not yet advocate to be combined to produce higher levels of microorganism deactivated by FUV photon and UV-C photon.Remote UV photon source targeting
Peak absorbs the nitrogenous base absorption bands at 200nm, and UV-C photon source targets other nitrogenous base absworption peaks (282nm) and ammonia
Base acid absworption peak (254-265nm).Be used alone compared with arbitrary photon source, applying of multi-wavelength UV photon is killed in cause of disease
Or inactivation aspect creates improvement.
In the several years in past, become commercially available based on the new UV emitting lamps exciting of excimers.These
Transmitter produces single line or narrow spectrum is launched, and it is launched wavelength and is formed decision by the gas of lamp.If selection process lamp wavelength with
The absworption peak of close match microorganism different component absorption bands, then can be delivered to micro-in the short period of time by lethal dose
Biological.Do not find any patent instruct use have support device with united FUV source, UV-C source, it can effectively and have
Efficient the air of the large volume in each preparatory phase, big surface and little surface and food are carried out disinfection and sterilize.
In this manual, sterilization functions or sterilizing refers to that sterilization functions or the high level disinfection being defined by US FDA are made
With.Disinfectant or disinfective action refer to the disinfective action of every other level.
The genomic constitution of all viable biological is included in its DNA molecular.Replicate and sent out by the division of DNA molecular
Raw, and DNA molecular replicates itself by the conversion of its structure.The each several part of DNA molecular has been named as such as pyrimidine base
Base, cytimidine, thymidine or uracil, it forms the one group of biochemicals sustaining life.Length dna molecule by use with
See similar simple connection of those in sugar and keep together.
Researcher thinks that the energy of GUV photon causes producing between specific biochemicals the shape of strong (covalency) key
Become.But, the bond strength of covalent bond is highly dependent on the relative position participating in atom.Bilateral symmetry when key hydrogen atom in key
When, call it as dimer.Dimer is very strong key, and generally will not rupture during liquid gasification.Known GUV light
Produce thymine dimer, cytimidine-thymine dimer and cytosine dimers.After forming dimer, DNA enters
The duplication of one step stops.Fig. 1 shows and forms dimeric principle in DNA molecular.
DNA molecular absorbs from about 180nm to the light of about 400nm.Use the commercial sterilization lamp exciting based on mercury, this is because
Its photon sending is close to the 260nm absworption peak of DNA amino acid.Mercury gas in lamp and pressure thereof determine the ripple launching light
Long.For low pressure (LP) and low pressure high output (LPHO) lamp, a length of 254nm of transmitted wave.For middle pressure lamp, transmitting boundary is
200nm is to higher than 400nm.But, for continuous emission lamp, the emitted luminescence intensity less than 245nm is invalid；And for middle pressure
Lamp, the emitted luminescence intensity less than 235nm is invalid.Xenon in flashlight produces the multi-wavelength similar with medium pressure mercury lamp and sends out
Penetrate.But, to this patent it is essential that amultiwavelength source produces two different narrow spectrum widths (commonly referred to as single line) transmittings, its
At least two peak corresponding to microbial DNA absorbs chromophore.In other parts of this patent, this source is referred to as double-single line lamp.See
Report in document is proved the UV photon of other wavelength or low wavelength blue light can promote the reparation of impaired key, and allows biology
Restart duplication.This is often referred to as photoreactivation.
DNA action spectrum shows multiple peak, and it depends on the composition of the nitrogenous base constituting described biology and amino acid.Although
Shown that FUV photon is effective for breaking bonds, but the appropriate dual wavelength combination of FUV and UV-C may equally effectively or more added with
Effect.
Recent technical papers (Peak etc., UV action spectra for DNAdimmer induction.,
Photochemistry and Photobiology, 40,5 (613-620), 1984) show that dimeric formation is not to make DNA
The sole requirement of inactivation.The suction to different wave length photon for the different molecular group (molecular group) in length dna molecule
Receive the energy transfer that will strengthen between group.Compared with the single band photon only affecting minority group, damage or destroy these key bases
Group can more effectively make DNA inactivate.Still nobody completes the detailed of the inactivation efficacy of the different single line UV transmitters to work in combination
Thin research.
A lot of document is had to relate to the multi-photon effect to material, owing to the energy of different photons can resonate or at the electricity of molecule
Producing different energy levels in son or atom, it can produce different processes.Principle in this specification is to use by identical
