Description
Technical field
The present invention relates to sterilization technology fields, and in particular to a kind of ionization hydrogen peroxide synthesis plasma sterilization skill
Art.
Background technology
It is net that the method that Chinese pharmacy corporation generally uses formaldehyde fumigation at present carries out biology to clean areas such as production, laboratories
Change, such as has：Formaldehyde fumigation, Peracetic acid, vaporized hydrogen peroxide, sporicide wiping etc..But existing each side's surface technology
There are a large amount of shortcoming, formaldehyde fumigation, although effect can reach requirement, its longer cycle period, for people
The harm of member（High carcinogenic material）Etc. reasons, America and Europe forbidden for space disinfection, sterilizing, with Chinese pharmacy
The raising of the standard and understanding of industry and drugs manufacture equipment industry is also gradually abandoning formaldehyde.And vaporized hydrogen peroxide（High temperature from
It solves hydrogen peroxide liquid and forms perhydroxyl radical）Its bactericidal properties and use cost with wide spectrum is low, noresidue harm etc.
Reason gradually starts to promote in China, but people also gradually recognize deficiency therein during popularization：Such as equipment
It is of high cost, equipment volume is huge, higher to air-conditioning system and curstomer's site infrastructure and equipment requirement and need
A large amount of flow-disturbing ancillary equipment, and a large amount of corrosivity case all greatly limit pushing away for vaporized hydrogen peroxide sterilization technology
Row.
Invention content
In view of the shortcomings of the prior art, purpose of the present invention is to be to provide a kind of ionization hydrogen peroxide synthesis etc. from
Daughter sterilization technology, the technology derive equipment volume is small, light-weight, fungicide can fast free diffusion, do not need any auxiliary
Unit is helped, it is almost without any requirement to the epidemic disaster of sterile field, it is even more important that this technique eliminates gasification peroxidating
The corrosion problems that hydrogen technology may be brought, while gas concentration is lower, it is more safe and reliable to personnel, environment.
To achieve the goals above, the present invention is to realize by the following technical solutions：Ionize hydrogen peroxide synthesis etc.

Buffer tank pressure superelevation, and in the case that carrier gas system does not make corresponding measure, safety relief valve can start automatically, ensure equipment
The safety of personnel.
When c, starting atomization, whether proximity sensor detects liquid storage bottle in place.Start pump and liquid storage bottle liquid is transported to mist
Change device, and situations such as strength of fluid, temperature is detected, and data feedback is arrived by liquid filter, liquid sensor
Controller, pressure sensor will be collected into data feedback to controller 1, so that it is determined that the action of pump.
D, according to the case where bactericidal agent transport system, carrier gas transport process system to plasma module hair occurs for sensor
Module occurs for the number of delivering letters, plasma, according to the signal of controller, can be sent to atomizer just or negative charge generates electricity
Pressure, voltage value can be set according to actual conditions, can also carry out positive and negative alternately output.
E, electrode occurs for ion close to atomizer exit, and the high-tension current of the high electric arc of generation, stimulation atomization column, formation will
Disinfectant and air can be dissociated, the molecular structure of disinfectant and air is destroyed, forms the disinfection ionic species group of ionic state.With this
High-tension current is mutually exclusive by like charges on sterilizing gas band simultaneously, more rapid to be abound with sterilized space.And pass through
Positive and negative adjustment can be more in line with the demand of environment sterilizing.The purification in space is completed faster.
F, controller connects device sensor, can be warm and humid with immediately monitoring environmental parameter, including sterilizing gas concentration, environment
It spends, the levels of hazardous gas in environment, if reach the parameters such as dangerous values, corresponding judgement is then made by controller, is given
Go out processing and executes signal.It is especially complex or when generator apparatus is not placed in the environment in environment, it can be external by extending
Sensor come have the function that detect environment specific position.When equipment is placed in sterilized environment, operating personnel can pass through
Remote controler carrys out start and stop equipment.
The invention has the advantages that：
1, it is long to solve the formaldehyde fumigation time, remains to human injury's problem；
It 2 while solving hydrogen peroxide generator, needs to sterilized environment flow-disturbing, it is slow to be otherwise easy that there are gas diffusions
Slowly, sterilize dead angle, require environment temperature, humidity high problem；
3, conventional high-temperature dissociation is eliminated（Vaporized hydrogen peroxide sterilization technology）The corrosivity and high concentration that process bands are come
Gas a series of problems caused by personnel safety brings safer operating procedure by dissociation technology at room temperature and atmospheric ionization.
4, the equipment for realizing biological cleaning by this technology can accomplish that small, low energy consumption, and low to space requirement is excellent
Point.
