Abstract
A disinfecting method and equipment with ozone and ultrosonic wave features that the ozone gas generately by ozone generator is introduced to the water contained in a disinfecting drum, the object to be disinfected is put in the water, and the ultrasonic wave at 20 KH2-3MH2 and 0.2 W/sq.cm generated by an ultrasonic generator are emitted into the water.
Description
The present invention relates to a kind of disinfectant method, is a kind of sterilization method and device thereof of supersonic wave cooperating with ozone specifically.
Can cause the pathogenic microorganism that the human or animal is sick, be a kind of harm humans life and health, perhaps causes the harmful microorganism of economic loss to people.In struggling with pathogenic microorganism, people not only need to kill the microorganism of the intravital growth and breeding of intrusion machine, but also should kill or remove the pathogenic microorganism of external environment, avoid it with the protection crowd and infect, and this task is finished by sterilization.Therefore sterilization is for keeping off infection with other disease, preventing that the infection in the hospital, the pollution of elimination biological warfare agent all have crucial meaning.Because hospital promptly is the place that microorganism is concentrated, it is again the place that the crowd that has a low resistance concentrates, and also have the special way of contact between the people, and therefore sterilization is to preventing that the infection in the hospital has the meaning of particular importance, comparatively typical sterilization is the surgery sterilization.
The most frequently used sterilization method has two big classes at present, and a kind of is physical disinfection method, and another kind is the chemical disinfection method.Modern Disinfection thinks that sterilization method is to utilize disinfectant solution comparatively reliably at present, i.e. chemical disinfection method is especially at the killing of human body skin surface pathogenic microorganism, as surgery hands sterilization or the like.And the method for chemical disinfection has following defective inevitably: one, and chemical liquid has detrimental effect to the skin of human body, and secular use can cause dermopathic generation, and this skin degerming when need are performed the operation is particularly evident; Its two, the toxic difficult decomposition of chemical liquid causes comparatively serious environmental to pollute during use; Its three, not reproducible use, the relative raising that causes disinfection cost.Though and there is not the defective of above-mentioned chemical disinfection in the method for physical disinfection, but because of disinfectant effect instability, unreliable, therefore can not be widely used the occasion of sterilization being had relatively high expectations, particularly sterilization be required very strict surgical operation sterilization aspect in various.
In the modern age Disinfection, ozonization is drawn attention by people.Because ozone is a kind of known strong oxidizer, relies on its powerful Oxidation and sterilize.It can oxidation Decomposition glucoseoxidase, the dehydrogenation oxidation enzyme of antibacterial, can also be directly and antibacterial have an effect, cause the destruction of the material of antibacterial, thereby destroyed growth and the reproductive process of antibacterial for the oxidation-reduction process of penetrating, cause the death of antibacterial.Ozone is a kind of wide-spectrum bactericide, brood body that can killing bacteria and brood cell, virus, fungus, protozoon encapsulation etc., and can destroy Botulinum toxin, be considered to a kind of wide spectrum, high effect disinfectants.But, under 270 ℃ of high temperature, can be converted into oxygen immediately because the ozone stable extreme difference can decompose at normal temperatures voluntarily; The 1% aqueous solution half-life at normal temperatures and pressures is 16 minutes, so when with ozone solution during as disinfectant, just can play sterilization effects when having only it to reach finite concentration, but because its own particularity of above-mentioned ozone, be difficult to be maintained at an effective or higher bacteriocidal concentration, guarantee the disinfectant reliability.So at present ozone only is applied to the disinfectant soup water, perhaps to the sewage disinfection of hospital etc., and still be not applied to others disinfectant report about ozone, especially should require high situation to sterilization in those, for example, operating skin degerming etc.
Why the inventor can not reach the reason that is widely used through a large amount of ozone that experiment showed,, except that above-mentioned well-known reason, Another reason be ozone to action of microorganisms the time, its penetration capacity is relatively poor.Analyze from microbiological angle, though its form of various antibacterial varies in size, its structure is similar.Be that each antibacterial all has four kinds of basic structure-cell wall, cell membrane, ribosome, nucleoid.And ozone is wanted oxidizing bacteria must contact antibacterial and acts on effective site just can realize.Because ozone is a kind of active oxygen, it trends towards elecrtonegativity, and various microorganism has negative charge in its surface in nearly neutrality or weakly alkaline environment, so electronegative ozone that becomes is difficult near antibacterial.Secondly, bacterium surface is the huge area structure of lipotropy, and this structure makes it very easily Organic substance is adsorbed in own surface, forms the fat protecting film.And the fat material has negative charge usually, thereby more increases its repulsive interaction to ozone.The 3rd, the aqueous solution of ozone is the hydrophilic strong oxidizer.According to the similar compatibility theorem, hydroaropic substance is difficult near lipophilic substance on the one hand; On the other hand, the more important thing is that strong oxidation reaction passivation takes place for ozone and Organic substance, form fine and close strong oxide-film, thereby make ozone be difficult to see through again the effective site that oxide-film acts on antibacterial at bacterium surface.Have, ozone water solution concentration is lower again, is difficult for forming Concentraton gradient, and this also is its penetration capacity extreme difference, effectively the another reason of killing microorganisms.Be subjected to pH value and organic substance influence bigger so on macroscopic view, show as the Ozone Water killing microorganisms.
In a word, the physiological property of antibacterial and the physicochemical property of ozone are the major reasons that hinders ozone extensive use aspect sterilization and sterilization, particularly require high medical science sterilization aspect.
The objective of the invention is to overcome the deficiencies in the prior art, and provide a kind of sterilization method that utilizes ultrasound wave and ozone cooperative, make it can increase the penetration capacity of ozone, required ozone concentration when both having reduced Ozone Water as disinfectant, with stability and the reliability of guaranteeing ozonization, shortened disinfecting time again, realize the popularity of the application of ozonization, particularly make it can be applied to surgery human body skin disinfectant field, thereby reach the purpose that substitutes existing chemosterilant, fundamentally eliminate by the caused infringement of chemosterilant human body, and pollution on the environment, disinfection cost reduced.
The purpose of invention is achieved in that and it is characterized in that a kind of sterilization method of supersonic wave cooperating with ozone water at first charging into ozone gas in being contained in the water of container, forms ozone concentration at least greater than the ozone water solution of 0.2PPM; Insert desire sterilization thing again, start ultrasonic generator, ultrasound wave acts on this ozone water solution, and ultrasonic frequency should be 20 KHz～3 megahertzes, and ultrasonic intensity is at least 0.2W/cm
2
The decontaminating apparatus of supersonic wave cooperating with ozone water of the present invention includes one at least and is container-like Sterilizing cylinder, is loaded with liquid in this Sterilizing cylinder; It is characterized in that, but this Sterilizing cylinder conducting utilizes this ozone generating-device to charge into the ozone gas that its concentration is no less than 0.2ppm in the liquid of tube in an ozone generating-device; Sterilizing cylinder is provided with supersonic generator, launches ultrasound wave by this supersonic generator in Sterilizing cylinder.
As everyone knows, ultrasound wave is a kind of physical disinfection method of routine, and its disinfective action is proved already.By present a kind of general result of study, utilizing ultrasonic sterilization mainly is to utilize cavitation effect of ultrasonic waves.Cavitation is meant that liquid is when action of ultrasonic waves, the micro-bubble in the intravital Asia of liquid is owing to directed diffusion trends towards increasing, when bubble increases to hyperacoustic wavelength difference not for a long time, resonant cavity just takes place, it is very big that amplitude can reach, so produce fierce energy, this cavitation is to make antibacterial to break, dissolve.Cavitation effect is a kind of peculiar physical phenomenon in the liquid medium under the ultrasound wave effect, can learn according to hyperacoustic cavitation threshold curve, when ultrasonic frequency is that 10～100KHZ, intensity are greater than 5W/cm
2And after acting on 20 minutes, bacterial propagule is had certain killing action, and relatively poor to the killing effect of bacterial spore.In addition, when ultrasound wave with frequency 10～100KHZ, intensity is greater than 5W/cm
2When acting on object surfaces, can corrosiveness be arranged to object surfaces, life-time service can have infringement to the skin of human body; (frequency 0.75-1.5MHz, intensity is less than 3W/cm with ultrasound wave and for physical therapy
2) lost killing action to antibacterial, physical therapy can not be applied to sterilization to human body skin separately with ultrasound wave for this reason.A large amount of evidences, though physical therapy does not have germ-resistant effect with ultrasound wave, but stronger penetrance is arranged, particularly microorganism is in ultrasonic field, each particle is subjected to the pressure of alternate, causes the intracellular matter motion, and cell membrane demonstrates fine massage effect, improve its penetrance, strengthen disperse process.Secondly produce the effect of acoustic streaming owing to acoustic streaming in the cell, cellularity generation phase transition presents new enzyme center, and the catalytic process tropism is changed, thereby cell is strengthened the sensitivity of medicine, is referred to as hyperacoustic activation among the present invention.And the non-cavitating effect, so body surface there is not any damage.The present invention utilizes hyperacoustic this characteristic just, reaches the purpose of disinfection by the penetrance effect synergy ozone of ultrasound wave pair cell.
The sterilization mechanism of kill bacteria of the present invention is such,
One, the cells physiological characteristic can be learnt,
1, the surface area of antibacterial is big, is 10,000 times of normal biological cells, and the surface area of antibacterial greatly then helps carrying out mass exchange with the external world, so the metabolism of antibacterial is vigorous, breeding rapidly;
2, the antibacterial area is not only big but also be netted lipotropy structure, so plate easily is adsorbed in Organic substance own surface formation fat protecting film;
3, the electrification phenomenon of antibacterial, bacterioprotein is made up of aminoacid, and aminoacid is the ion of holding concurrently, and when the pH value of this solution was higher than the antibacterial isoelectric point, IP, carboxyl ionization made antibacterial electronegative, on the contrary positively charged.G
+PI is 2～3, G
-PI is 4～5, so in nearly neutrality or weakly alkaline environment, antibacterial is electronegative more.
Two, the physicochemical property of ozone:
1, ozone is that the elecrtonegativity of becoming is arranged;
2, the aqueous solution of ozone is the negative strong oxidizer of hydrophilic;
3, the dissolubility of ozone in water be than oxygen height, but short and dividing potential drop is lower because of the half-life, so under serviceability temperature and pressure at ordinary times, can only obtain every liter several milligrams concentration solution, so difficult formation Concentraton gradient.
As everyone knows, ozone is strong oxidizer known to the present people, but the effective site (cell membrane and content) that it wants oxidizing bacteria must act on antibacterial just can realize.But we according to the physiological property of antibacterial as can be known, and in nearly neutrality or weakly alkaline environment, antibacterial is electronegative, so electronegative ozone that becomes is difficult near antibacterial; Tool, bacterium surface is the huge area structure of netted lipotropy, this structure makes it very easily Organic substance is adsorbed in own surface, forms the fat protecting film.And lipid material is normally electronegative, thereby more increases its repulsive interaction to ozone.Three, the aqueous solution of ozone is the hydrophilic strong oxidizer, and on the one hand according to the similar theorem that mixes, hydroaropic substance is difficult near lipophilic substance; On the other hand, strong oxidation reaction takes place and produces purification in what is more important ozone and Organic substance, form fine and close oxide-film at bacterium surface, thereby make ozone be difficult to see through again the effective site that oxide-film acts on antibacterial, there is ozone water solution concentration lower again, be difficult for forming Concentraton gradient, this also is its penetration capacity extreme difference, effectively the another reason of killing microorganisms.Be subjected to pH value and organic substance influence bigger so on macroscopic view, show as the Ozone Water killing microorganisms.
In a word, the physiological property of antibacterial and the physicochemical property of ozone are the major reasons that hinders ozone extensive use aspect sterilization and sterilization, particularly require high medical science sterilization aspect.
Three, the bacteriology's effect under the ultrasound wave effect:
1, the cavitation effect under the low-frequency ultrasonic waves effect: cavitation is a kind of physical phenomenon in the liquid medium.Owing to eddy current or hyperacoustic physical action, a certain zone in the liquid can form local temporary transient negative pressuren zone, so can produce cavitation bubble in liquid medium in liquid medium.Continue along with change of sound field to grow up at ultrasonic field cavitation bubble, reach maximum up to negative pressure, in back to back compression process, these cavitation bubbles are compressed, and its volume dwindles rapidly, have in addition complete obiteration, when the resonance phase place of deviating from ultrasonic field, cavitation bubble is just no longer stable, and at this moment the pressure in the cavitation bubble no longer can support the size of himself, and the beginning collapse.The phenomenon of the generation in liquid medium of this cavitation bubble, collapse or disappearance just is called cavitation.Cavitation to the effect that showed biology cavitation effect.This cavitation effect is a kind of violent conversion process of energy, cavitation bubble moment is compressed, collapses, it is local to produce high temperature, high pressure, luminous, discharge, impact and involve free radical etc., this process as the blast around antibacterial of countless miniature bombs, is irreversible destruction to organism especially.
2, the activating effect under the middle frequency ultrasonic effect
1) electrostatic charge reduces (even the bacterium surface negative charge reduces) on the cell membrane, causes the cell electrophoresis ability drop;
2) the vibration current potential that causes under the effect of ultrasonic field of cell membrane and the fine massage effect permeability that makes cell membrane strengthens;
3) under the effect of alternation acoustic pressure, produced stronger cell oleo stock miniflow (or claiming circulation), thereby promote moving of cellular content, change its spatial mutual alignment, present new enzyme center, the trend of catalytic process is changed, and cell is to the responsive of medicine thereby change;
4) but the activity of the plurality of enzymes in alternation acoustic pressure irritation cell film and the content metabolism of cell is strengthened, thereby quickens the vegetative speed of binary fission of antibacterial, shorten its generation time.
Activating effect is a kind of reversible, and comparatively Wen He biomembrane and content thereof are under the effect of alternation acoustic pressure and the activation effect that causes.
3, the heat effect under the high-frequency ultrasonic effect:
Frequency of ultrasonic is high-energy decay fast more more, and the energy that attenuates mainly is to change into heat energy to be absorbed by medium, and the main mechanism of bio-absorbable is organic protein intramolecularly or intermolecular relaxation process.This class conversion of acoustic energy and molecular energy is irreversible, its endergonic major part or all be converted to heat energy, thereby cause the rising of temperature, it is stable that the temperature that this absorption acoustic energy causes raises, and temperature raises protein active is strengthened even degeneration necrosis.
In a word, the bacteriology's effect under the ultrasound wave effect is the comprehensive function of these three kinds of effects, and only which effect accounts for dominant advantage under different frequencies, intensity and model of action.Usually, under the identical situation of intensity, low frequency is based on cavitation effect, and intermediate frequency is based on activating effect, and high frequency is based on heat effect.
Four, the collaborative effect of ultrasound wave and Ozone Water to antibacterial:
1, the collaborative effect of the cavitation effect of low-frequency ultrasonic waves and Ozone Water to antibacterial:
Cavitation effect itself is a kind of violent energy conversion process, the ultrasonic field energy is that compression and the collapse by cavitation bubble changes into heat energy, luminous energy, electric energy, chemical energy, mechanical energy (shock wave and sound wave) in moment, this violent energy conversion process, make the physiological property of antibacterial that the structure that extremely complicated variation has directly destroyed cell wall, cell membrane and the content thereof of antibacterial take place, the cell disruption thing is exposed in the ozone water solution; Secondly, this violent conversion process of energy is strengthened the strong oxidation reaction ability of ozone again.In a word, the resultant effect of heat, electricity, light, chemistry, machinery and ozone cooperative that the collaborative effect to antibacterial of the cavitation effect of low-frequency ultrasonic waves and Ozone Water is a complexity, the effect of its collaborative killing microorganisms is very remarkable.
2, the collaborative effect of intermediate frequency ultrasonic activation effect and Ozone Water to antibacterial:
At first, the surface negative charge of antibacterial minimizing helps ozone near antibacterial;
Next, the permeability of film strengthens the ozone permeate through cell membranes that helps low dividing potential drop and enters in the antibacterial;
The 3rd, the metabolism and the asexual propagation speed of cell have been quickened in the enhancing of surface of cell membrane and content enzymatic activity.At this moment, various enzymes very easily are subjected to the oxidation of ozone in the antibacterial, destroy its 26S Proteasome Structure and Function.Simultaneously since bacterium surface long-pending be 10,000 times of normal biological cells, so sustain damage death and other biological cell no change of antibacterial in the case.
The 4th, the high frequency mechanical oscillation destroys the organic protective film of bacterium surface and the passivating film behind the ozonization, the penetration capacity of ozone is strengthened, thereby shortened the oxidizing process of ozone to antibacterial;
The 5th, all right accelerate ozone of hyperacoustic dispersion is in the intravital diffusion of antibacterial.
In a word, the excusing from death ripple is gentle, reversible activation effect to the activation of antibacterial, have only and when ultrasound wave and Ozone Water are collaborative, just have the above-mentioned process of killing, this process does little harm to normal biological cells, and it is bigger for the infringement of antibacterial, so this process helps being applied to the sterilization aspect to skin.
When 3, high-frequency ultrasonic heat effect and Ozone Water are collaborative to the effect of antibacterial:
Because mainly being the form with heat energy, the conversion of high frequency ultrasound wave energy transformed; And because this conversion mainly is organic protein intramolecularly or intermolecular carrying out, institute is so that the increased activity of pheron in sound field, and promptly the activity of antibacterial strengthens to some extent, thereby makes the sensitivity enhancing of antibacterial to ozone.When temperature is too high, can make protein denaturation, directly killing bacteria.
In sum, the effect of the collaborative kill bacteria of ultrasound wave and Ozone Water is the comprehensive function of above three kinds of effects.Wherein a kind of effect accounts for dominant advantage under different frequency and the intensity.Usually, under the identical situation of intensity, low frequency is based on cavitation effect and the collaborative kill bacteria of Ozone Water; Intermediate frequency is based on activating effect and the collaborative kill bacteria of Ozone Water; High frequency is based on heat effect and the collaborative kill bacteria of Ozone Water.
And among the present invention, according to the sterilization mechanism of above-mentioned supersonic wave cooperating with ozone water, by selection to ultrasonic frequency and intensity, and with the different coupling combination of consistency of ozone water, can realize the Disinfection Effect of different sterilization places and different sterilization thing.To be respectively described below with different embodiment below.
The conclusion of being not difficult to draw by above-mentioned explanation is, the present invention compares effect with existing disinfection technology be significant, because three kinds of different effect of above-mentioned ultrasound wave, changed the cells physiological characteristic, and the change of this physiological property, more help strengthening the Oxidation of ozone, as cell membrane and content to antibacterial effective site.Therefore, still can reach Disinfection Effect preferably under the lower situation of the ozone concentration in Ozone Water, thereby reduce the bacteriocidal concentration of ozone widely, guarantee its disinfectant reliability; Reduce in the disinfecting process injury of human; Under the situation of increase to the ability of killing of antibacterial, reduce the ozonization cost, ozone more is widely used in the different sterilization fields, to substitute the chemical disinfection method comparatively widely of using at present, fundamentally solve by caused injury of human of chemical disinfection and problem of environmental pollution, disinfecting time is long, disinfectant can't be reused, problems such as disinfection cost height.
