Description
Technical field
The invention belongs to microorganism sterilizing field, be specifically related to a kind of VHP plasma (orifice) gas colloidal sol and send out
Generation method and device.
Background technology
Hydrogen peroxide, chemical formula is H2O2, its aqueous solution is commonly called as hydrogen peroxide, and outward appearance is colourless
Prescribed liquid, is a kind of strong oxidizer, it is adaptable to wound disinfection and environment, food sterilization.
The history that the bactericidal property of liquid hydrogen peroxide gets the nod existing more than 100 year, has
The feature of environment-friendly high-efficiency.But, the exigent concentration of liquid hydrogen peroxide and the longest contact
Time, just have and kill spore ability.Later, it has been investigated that gaseous hydrogen peroxide is at low concentration
State under than having higher spore ability of killing in a liquid state, cardinal principle is to generate trip
From hydroxyl, for attack cell component, including lipid, protein and DNA, thus reach
To the inactivation to antibacterial.Therefore occurs being vaporizated into the hydrogen peroxide vapour of gas form on market
Change method and vapour producer.Hydrogen peroxide steam is hydrogenperoxide steam generator heating to be vaporized, by
After liquid becomes gas, unit volume will be enlarged by 1000 times, therefore, it is possible to be full of whole rapidly
Individual sterilized space, and than spraying, there is higher penetration capacity, sterilising cycle is short, and economy is strong.
Existing hydrogen peroxide gasification method and principle of device are roughly divided into:
1) heating flash evaporation method: drop in high-power heater by hydrogen peroxide drop, by liquid mistake
Hydrogen oxide evaporation becomes steam state.The method of this vaporized hydrogen peroxide is relatively simple, and cost is relatively low,
Use wide, but have the disadvantage that the particle size distribution of the hydrogen peroxide steam 1. vaporized
Scope is wide, it is impossible to controlling steam particle size, so being easily condensed into drop, sterilization effect is poor；
2. heating power consumption is too big, and sterilizing energy consumption is big；3. vaporized hydrogen peroxide temperature is higher, meets cold easy knot
Dew, is condensed into liquid.4. the hydrogen peroxide particle size distribution vaporized is extensive, so easily adhering to
Being difficult to remove at body surface, residual quantity is bigger.5. hydrogen peroxide is divided because of vapourizing temperature height
Xie Weishui and oxygen, make the operation efficiency of hydrogen peroxide reduce.
2) gases at high pressure nebulization: use venturi principle, uses gases at high pressure laterally to blow slotting
Enter the micro cautery of hydrogen peroxide liquid, after being blown out by liquid, become vaporific.This mode is easily real
Existing, cost is relatively low, more simply.But have the disadvantage that the hydrogen peroxide mist particle 1. vaporized
Footpath is widely distributed, is easily condensed into drop, and sterilization effect is poor, and bulky grain is compared with the attached work of free settling simultaneously
At body surface, residual quantity is relatively big, is difficult to remove；2. spraying system volume is big, is unfavorable for setting
Standby miniaturization；3. gas consumption is relatively big, and gases at high pressure just can use after needing individual processing.
3) after the atomization of ultrasound wave hydrogen peroxide, high pressure plasma becomes OH-hydroxyl: use ultrasonic
Hydrogen peroxide liquid is become hydrogen peroxide micropartical by ripple, then through electrion by hydrogen peroxide
Grain ionization is hydroxyl radical free radical (OH-).The advantage of this kind of method is that sterilization effect is good, and efficiency is high.
Its shortcoming is: 1. because of hydroxyl radical free radical (OH-) band alkalescence, be easier to acid gilding metal surface；
2. it is ionic condition because of hydroxyl radical free radical (OH-), unstable, it is impossible to keep for a long time freely
State, easy and Organic substance is combined into the materials such as alcohol (ROH), phenol (ArOH), benzene.
