Description
Technical field
It is sterilized in refrigerator-freezer the present invention relates to a kind of plasma generator and its control circuit and using the device
The method of deodorization.
Background technique
Refrigerator-freezer is used to cryo-conservation food, and in-cabinet temperature is low and atmosphere draught-free, bacterium easily breed, and is also easy production foul smell
It is not easy to be discharged that (foul smell main ingredient is NH3And H2S)；So that the environment in refrigerator-freezer is unable to improve, and may accelerate in refrigerator-freezer
Becoming morally degenerate for food, " psychrophile " most common in refrigerator-freezer have formula bacterium and Listeria, they can cause a variety of diseases, danger
Evil human health, so, refrigerator-freezer wants periodic cleaning to sterilize, it first has to weekly at least to clean refrigerator-freezer, degerming, disinfection,
Secondary method is correct, other than to simultaneously the conventional position in refrigerator-freezer inside is cleaned, sterilized, should more focus on special with efficient refrigerator-freezer
With disinfectant, injection disinfection is carried out come dead angles such as drip, septaliums to refrigerator-freezer and is answered after the completion of refrigerator inner wall, dead angle are spraying
This closes freezer door 5-10 minutes, allows disinfectant sufficiently to sterilize, is finally wiped clean again with rag, and when above-mentioned each cleaning is both needed to
Using appropriative disinfector, required cost is big, and the process cleaned is very complicated, need to consume a large amount of time, before cleaning, ice
There can be a large amount of bacteriums in cabinet, a variety of diseases can be caused, in addition, refrigerator-freezer manufacturer also has by using ultraviolet lamp (UV lamp) Lai Jinhang
Sterilization, deodorization, fresh-keeping, this mode is achieved the goal by light direct projection, even if each corner multi-angle is placed in refrigerator-freezer
UV lamp, it is also possible to dead angle is produced because the size of food stored in refrigerator-freezer, it is ineffective, and also ultraviolet light has human body
Evil.

Apparatus above is placed in refrigerator-freezer, deodorization and sterilization process is done in detail below by working principle and working method
Explanation.
According to the formation mechenism of Townsend avalanche theoretical explanation negative corona.For negative corona discharge, come out from emission of cathode
Free electron under the action of electric field force along direction of an electric field displacement, in moving process in air molecule or atom send out
Raw collision.New electronics is generated after molecule or atom are free and original electronics continues on electricity under the action of electric field force together
Field direction movement, while causing new dissociate.When electric field strength is more than certain critical value, electron beam can be sharply increased.In electric field
Under the action of power, electronics develops along the direction of principle cathode conductor.
Under Townsend avalanche is theoretical, if assuming to be uniform field everywhere, charging particle movement is not considered based on directed movement
Spatial compounding and chamber wall are compound, ignore cation in the ionization by collision in space, discharge current size may be expressed as:
IoFor saturation current, αTFor townsend ionization coefficient, it is defined as the electricity that electronics is generated in direction of an electric field by 1CM distance
Average from collision.
For αTIt can be calculated with air pressure p and field strength E.If assuming, electronics based on directed movement, and is ignored in gas
Exciting collision, relation formula are
αTIt can also be calculated with following formula
Wherein, A, B are constants related with gas property.P is air pressure, and d is interelectrode distance, and v is voltage
Electron and molecule or atom collide, and collide the electronics of generation to anode movement, the cation stayed then exists
Slowly to movable cathode under the action of electric field force.When voltage increase to a certain extent so that these cations reach cathode, yin
Pole surface generates new electronics.This is cathode secondary.These new electrons are under the action of electric field to anode
Movement, and electron avalanche is generated, repeat process above.
Under corona discharge, air can be dissociated into plasma.Generally there are six kinds of particles for cold plasma discharge: light
Son, electronics, ground state particle and negative ions, excited state particle, various particles can be collided mutually, be interacted, and then influence it
His particle.
Elastic collision and inelastic collision are two kinds of main Types of particle encounter, in elastic collision, only change particle
Speed, its position of particle for participating in collision can not change, therefore atom or molecule cannot be excited or dissociate, to chemical reaction
Do not contribute.In inelastic collision, interparticle aggregated momentum is constant, but total kinetic energy non-conservation.In other words at least one
The energy of particle is changed.
There are the forms of a variety of collisions for plasma, are broadly divided into three kinds:
Excitation: atom or molecule can absorb the kinetic energy and photon of electronics after inelastic collision occurs for electronics or photon
Energy, so that atom and the interior of molecule can increase, the energy of absorption makes the electronics in atom transit to high level by low-lying level.This
One process is known as the excitation of atom.
Ionization: atom or molecule are caning absorb their energy with electronics, neutral collisions, or while acting on photon.
When absorbing energy more more than energy needed for transitting to outermost level in an impact, electronics can be detached from it is nuclear about
Beam becomes free electron.This process is known as ionizing.
Compound: positive charged particle and negative charged particle can also collide.Positive charged particle and negative band electrochondria
New particle is formed after son in electroneutral.
And ion sterilizing, deodorization, it is fresh-keeping in, just applying to these three principles.
In conjunction with Fig. 2 to Fig. 6, under the high voltage of needle point, the oxygen molecule in air can be forced to separate and reconfigure, and be formed
Micro ozone.Negative ions float under the carrying of vapor to bacterium and foul smell surrounding molecules.Negative ions absorb bacterium and
Hydrogen atom in foul smell molecule, and in conjunction with itself, hydroxy is formed, hydroxy can be with surrounding under the action of surrounding molecular
Hydrogen atom combines once again, forms hydrone.And bacterium and foul smell molecule can decompose death after losing hydrogen atom.To reach
Sterilization, deodorization, fresh-keeping effect.
Wherein oxygen molecule is made of two oxygen atoms under normal conditions.Valence bond theory thinks that oxygen molecule is by two oxygen originals
What son was combined into the form of double bond.Its structural formula mark are as follows: O=O
When ionizing, oxygen can be ionized with electron collision.The ionization energy of oxygen is up to 12eV, most electricity
It is indirect ionization from effect.
When energy is greater than 17eV, oxygen can be with direct ionization.Its product is O+And O-
O2+e→O++O-
When dissociating, oxygen atom is can be generated by the adsorption effect of dissociation in oxygen molecule
e+O2→O2 -→O-+O
Equal charge dissociations also produce oxygen atom
e+O2→e+2O
Compound tense is occurring, oxygen molecule can be compound with electronic action generation, but needs the participation of third party M.It is multiple
The product of conjunction is ion O- 2
e+O2+M→O2 -+M
Positive hydrogen ion can also be obtained by same principle
The structural formula of water is H-O-H
In plasma discharge, hydrone is broken down into H+And O2-, negative ions are medium into air using vapor later
It propagates, cluster ion forms OH base after striking bacterium and foul smell molecule, captures the H atom of mushroom, foul smell molecule, makes bacterium not
Activation, foul smell odorlessization.
