Description

There is the refrigerating equipment of electric sizing device

Technical field

The generation that the present invention starches with electricity is relevant, particularly relevant with the plasma generation apparatus be installed in refrigerator.

Background technology

Refrigerator is the indispensable apparatus of daily life, but refrigerator stores various fresh food because mixing, and causes being full of peculiar smell and bacterium in case, and most refrigerator is all furnished with deodorization sterilizing unit, as devices such as silver ion, ultraviolet, ferment and anions, precisely because usefulness neither and electricity slurry.On the other hand, vegetables and fruits can produce ethene by nature in the middle of the process of refrigerator storage, ethene is a kind of gas plant hormone, regulate or affect the physiological change process that the growth of many plants, growth and adverse circumstance cause, therefore the growth of ethene is effectively controlled, can effectively make the maturity period of fruit extend, and electricity slurry have splendid effect to the decomposition of ethene and suppression.

Electricity slurry is gaseous matter is dissociated into positive and negative particle state at elect magnetic field.Substantially slurry is powered on containing zwitterion, electronics, the free radical of high response and neutral particle.In the electric field, because the average free footpath (mean free path) of electronics is much larger compared with cation, therefore electronics can sharply be accelerated, be accumulate to very high energies (tens of eV), this high energy electron and atom or molecular collision, intramolecular bond can be interrupted and form the free radical (Reactive free radical) of high response, or atom, molecule being produced dissociate (Ionization) and carry out decomposition reaction.Dissociate produced electronics again by electric field acceleration, with atom, molecular collision, produce more electronics, ion or free radical, form chain reaction (Chain reaction), finally form the electric pulpous state state of tool high energy electron, high response free radical.United States Patent (USP) the 3212974th, 4275287 and No. 4778561 all have the technology mentioning that electricity slurry generates.

In the electric field, due to electricity slurry in electronic remote comparatively ion easily absorb energy, therefore in electricity slurry system, the temperature of electronics can up to Celsius several ten thousand or hundreds of thousands degree, and the temperature of other particles is then room temperature (usually only having tens DEG C).Because the reactivity of high-temperature electronic is extremely strong, to the destruction ultrahigh in efficiency of various molecular binding, so the electricity slurry of high response, the generally generable gas-phase reaction of ability more than 1000 DEG C can be made, can carry out a little more than under room temperature.

Under an atmospheric pressure, produce electricity slurry is a kind of mode that is most economical, full blast.General plasma manufacture is the generation making electricity slurry stable, under system must be operated at low pressure.Therefore need vacuum cavity and vavuum pump to maintain the environment of low pressure, not only cost raising, unit interval treating capacity subtract greatly, and equipment maintenance cost is also high.Such as, vavuum pump is neither corrosion-resistant and particulate generally, very easily impaired.If stable electricity slurry therefore can be produced at ambient pressure just no longer need above-mentioned vacuum equipment, device simplifies, and operation and maintenance cost reduce greatly, and its workpiece can not by the restriction of vacuum cavity size in addition, and processing procedure is easily with continous way operation, can treating capacity also significantly promote.Therefore atmospheric pressure plasma is compared to traditional low tension slurry, has greatly expanded the application of electric slurry.

Low tension is starched because the mean free path of electronics is much longer compared with other particles, thus the energy of other gases that enough dissociate can be obtained, but pressure be an atmospheric pressure at present, due to the frequent and mean free path of gas molecule collision very short, therefore electronics is difficult to accumulate enough energy to the gas molecule that dissociates, and thus cannot start electricity slurry.

Now, the mode that produce electricity slurry has two kinds: (one) improves the current potential of additional power source to several thousand volts, makes to obtain enough energy in the limited distance accumulation of electronics between twice collision, produces electricity slurry to carry out ion reaction; (2) provide a large amount of current flow heats gas molecule, form high-temperature electric slurry.In addition; atmospheric pressure plasma is starched compared to low tension; often can run into distinctive various discharge instability problem, that is atmospheric pressure plasma is easily confined to specific regional area, thus must use costliness but the dicyanogen of easily electric discharge or helium are overcome as process gas.

Due to above-mentioned problem, make electricity slurry be applied in refrigerator and still have technical difficulty, how to set up low cost and high efficiency atmospheric pressure plasma technology still for industry is making great efforts the problem of solution.
