Background technology
With the rapid development of chemical industry, the type and quantity of waste water rapidly increase, and produce more and more superelevation
Concentration organic wastewater seriously threatens the health and safety of the mankind.For ultra-high concentration organic wastewater, such as organic chemical synthesis work
Industry waste water and agricultural chemicals waste water etc., conventional oxidizing process and biochemical process have been difficult to be applicable in.
Evaporative crystallization method has been increasingly being applied in the processing of ultra-high concentration organic wastewater, with obvious effects.
However, for the waste water containing volatile organic matter, existing evaporation technology is often difficult to directly handle waste water up to standard, still needs to
Want subsequent processing.
Therefore urgent need exploitation one kind is simple and efficient, the wider array of evaporation technology of the scope of application.
Invention content
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 that gas occurs with air, is given birth to the mode that 100~120A DC currents discharge
At 2600~2900 DEG C of plasma of temperature；Above-mentioned plasma is sprayed by vaporization chamber bottom, and directly contacted with liquid into
Row heat and mass；Vaporization chamber is discharged in liquid heat absorption evaporation, the steam of generation together with plasma：Entrained by plasma
A large amount of elemental oxygens, ultra-oxygen anion free radical, ozone molecule and high energy electron have extremely strong oxidability, can will be in steam
Volatile organic contaminant be decomposed into carbon dioxide and water, improve removal of the evaporation technology to Organic Pollutants in Wastewater
Rate；Steam eventually passes through condensation and obtains evaporator water outlet.
Wherein：Using air as the generation gas of plasma.
Wherein：Air is provided in the form of compressed air.
Wherein：Plasma is generated by the way of the electric discharge of 100~120A DC currents.
Wherein：The plasma temperature generated is at 2600~2900 DEG C.
Wherein：Entrained a large amount of elemental oxygens, ultra-oxygen anion free radical, ozone molecule and high energy electron in plasma
With extremely strong oxidability, the volatile organic contaminant in the steam that can degrade.
Plasma generated in the method for the present invention, itself has high temperature, can provide heat for evaporation technology
Source；A large amount of elemental oxygens, ultra-oxygen anion free radical, ozone molecule and high energy electron are carried in plasma simultaneously, due to original
Big energy entrained by superpower oxidability and high energy electron possessed by sub- oxygen, ultra-oxygen anion free radical, leads to its oxygen
Change ability is much better than simple ozone, the volatile organic contaminant in the steam that can degrade to non-selectivity.
