When gas during, be provoked into to having extremely strong active plasma, thereby effectively kill the various pathogenic microorganisms of its region through the excitation area of excitation device.Whole sterilization process only need need not the thermal source condition by additional certain magnitude of voltage, and it is few to produce heat.
Selection at the excitation device of gas is diversified, and gas type wherein also is multiple, for example air, oxygen and nitrogen etc.Because oxygen easily is excited and can produces the ozone with fine sterilization and Disinfection Effect, be ideal selection, but higher with respect to costs such as air.Streamline type wherein also has multiple choices, for example knitting wool, cotton thread and linen thread etc.
After gas and the liquid mixing, the bubble distribution density is big, the bubble uniform distribution, and gas-liquid effectively contacts, and at this moment, bubble is wrapped in fluid column, forms typical " liquid-in-gas " effect.
The concrete selection of excitation device can be following two kinds:
Excitation device is a kind of channelled electromagnetic wave generator;
Excitation apparatus is the plasma generator that a kind of electric field with insulated channel causes effect, and it is made up of the electrode of insulated channel, these passage both sides that are placed in and the power supply that is electrically connected with this electrode.Produce electric field after the electrifying electrodes, this electric field passes on physical arrangement and the electrical conductance electrode and the isolated insulant of gas liquid mixture, thus the bubble in the excitation channel.
It also is multiple that the version of electrode and material are selected, for example, and lead, conductive metal mesh, conductive plate etc.The compound mode of positive and negative electrode also can be dissimilar, both can be similar combination, for example, and battery lead plate counter electrode plate, electrode network counter electrode net etc.; Also can be inhomogeneity (and class) combination, for example, battery lead plate counter electrode net etc.
Insulant only otherwise can produce chemical action with gas liquid mixture get final product, that uses always has glass, an epoxy resin etc.
The selected of electric discharge between electrodes gap is important, and effectively discharging gap needs that easy more to be excited and to be convenient to practical application be prerequisite with bubble.
In sum; technological merit of the present utility model and beneficial effect are; can effectively kill various pathogenic microorganisms; processed liquid can directly be utilized; shelf life is long; processing procedure is extremely simple again, and physicochemical properties and the various flavor substance and the nutrient substance of liquid can be effectively protected in heat production hardly.
