METHOD OF PLASMA CHEMICAL TREATMENT OF LIQUID RAW MATERIAL OF ORGANIC AND/OR VEGETABLE ORIGIN AND DEVICE FOR ITS IMPLEMENTATION

摘要

FIELD: technological processes.;SUBSTANCE: invention relates to a method for plasma chemical treatment of liquid raw materials, as well as to a device for such treatment and can be used in food, bioenergy, chemical and petrochemical industries. Method includes an electrical effect on water-containing raw materials of products of low-temperature plasma. Electrical effect is performed with a parameter value E/N₀=10^-6–10^-7 [V·cm²], where E is the electric field strength, N₀ is the concentration of charged particles in the discharge gap. At the same time, the gas medium is moistened, providing a moisture content of 20 to 100 %. Hydrogen index of a raw material is maintained at a level from 2 to 7, the conductivity of the raw material is maintained in the interval S=10^-2–10⁴ Cm. Device for plasma chemical treatment of liquid raw materials contains a plasma-chemical reactor, system for supplying and withdrawing raw materials, gas supply system above the irradiated component, and a power source. Power source provides the formation of an electrical discharge with volumetric electronic and ionic charges in a continuous or pulsed mode. Gas supply system is provided with a device for humidifying the supplied gas with water vapor.;EFFECT: effective disinfection of raw materials, which is subject to long-term storage, and improvement of efficiency of electric power utilization.;4 cl, 2 dwg
