The problem of the purpose of the present invention is to solve existing evaporation technologies and deficiency, provide a kind of simple height
Effect, the wider array of evaporation technology of the scope of application.
Technical scheme is as follows：It is excitation object with sulfate liquor, is discharged with 340~350A DC currents
Mode generates the plasma of 4700~4900 DEG C of temperature；Above-mentioned plasma is sprayed by vaporization chamber bottom, and directly and liquid
Contact carries out heat and mass；Vaporization chamber is discharged in liquid heat absorption evaporation, the steam of generation together with plasma；Institute in plasma
A large amount of potentiometric titrations, hydroxyl radical free radical and the high energy electron carried has extremely strong oxidability, can will be in steam
Volatile organic contaminant is decomposed into carbon dioxide and water, improves removal rate of the evaporation technology to Organic Pollutants in Wastewater；
Steam eventually passes through condensation and obtains evaporator water outlet.
Wherein：Using sulfate liquor as the excitation object of plasma.
Wherein：Sulfate is specially the salt containing sulfate ion such as sodium sulphate, potassium sulfate.
Wherein：Due to the difference of waste water quality, the amount of sulfate used is determined by lab scale.
Wherein：Plasma is generated by the way of the electric discharge of 340~350A DC currents.
