Description
Technical field
This utility model belongs to microorganism sterilizing field, is specifically related to a kind of VHP plasma aerosol generating device.
Background technology
Hydrogen peroxide, chemical formula is H2O2, its aqueous solution is commonly called as hydrogen peroxide, and outward appearance is colourless transparent liquid, is a kind of strong oxygen
Agent, 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 time of contact, just have and kill spore ability.Later, after deliberation
Finding that gaseous hydrogen peroxide has higher spore ability of killing when low concentration than in a liquid state, cardinal principle is
Generate free hydroxyl, for attack cell component, including lipid, protein and DNA, thus reach the inactivation to antibacterial.Cause
Occur being vaporizated into hydrogen peroxide gasification method and the vapour producer of gas form on this market.Hydrogen peroxide steam be by
Hydrogenperoxide steam generator heating vaporization, after becoming gas due to liquid, unit volume will be enlarged by 1000 times, therefore, it is possible to fill rapidly
Full whole sterilized space, and than spraying, there is higher penetration capacity, sterilising cycle is short, and economy is strong.
Existing hydrogen peroxide vapourizing unit principle is roughly divided into:
1) heating flash evaporation: drop in high-power heater by hydrogen peroxide drop, becomes vapour by liquid hydroperoxide evaporation
State.The method of this vaporized hydrogen peroxide is relatively simple, and cost is relatively low, uses wide, but has the disadvantage that the peroxide 1. vaporized
The particle size distribution scope changing hydrogen steam is wide, it is impossible to control steam particle size, so being easily condensed into drop, sterilization effect
Difference；2. heating power consumption is too big, and sterilizing energy consumption is big；3. vaporized hydrogen peroxide temperature is higher, meets cold easy condensation, is condensed into liquid.④
The hydrogen peroxide particle size distribution of vaporization is extensive, is difficult to remove so being easily attached to body surface, and residual quantity is bigger.
2) gases at high pressure spraying: use venturi principle, uses gases at high pressure laterally to blow and inserts the micro-of hydrogen peroxide liquid
Tubule, becomes vaporific after being blown out by liquid.This mode easily realizes, and cost is relatively low, more simply.But have the disadvantage that 1. vapour
The hydrogen peroxide mist particle size distribution changed is extensive, 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 device miniaturization；3. gas consumption is relatively
Greatly, just can use after gases at high pressure need individual processing.
3) after the atomization of ultrasound wave hydrogen peroxide, high pressure plasma becomes OH-hydroxyl: use ultrasound wave by hydrogen peroxide liquid
Become hydrogen peroxide micropartical, then through electrion, hydrogen peroxide granule is ionized as hydroxyl radical free radical (OH-).This kind of method
Advantage is that sterilization effect is good, and efficiency is high.Its shortcoming is: 1. because of hydroxyl radical free radical (OH-) band alkalescence, is easier to corrode metal watch
Face；2. it is ionic condition because of hydroxyl radical free radical (OH-), unstable, it is impossible to keep free state for a long time, be easily combined with Organic substance
Become the materials such as alcohol (ROH), phenol (ArOH), benzene.
