Description
Technical field
The utility model belongs to technical field of waste gas treatment, relates in particular to the emission-control equipment based on wet type DDBD.
Background technology
At present, low temperature plasma is material the 4th state after solid-state, liquid, gaseous state, when applied voltage reaches gasWhen discharge voltage, gas is breakdown, produces the mixture including electronics, various ion, atom and free radical. DischargedAlthough electron temperature is very high in journey, heavy particle temperature is very low, and whole system presents low-temperature condition, thus also referred to as low temperature etc. fromDaughter. Low-temperature plasma degradation pollutant is the pollutant utilizing in these high energy electrons, free radical isoreactivity particle and waste gasEffect is decomposed contaminant molecule within the extremely short time, and follow-up various reactions occurs to reach degradation of contaminantObject, the way of production of low temperature plasma is a lot, and the industrial waste gas of plasma in low temperature patent treatment technology of our exploitation, adoptsWith discharge type be: Multi-pole column screw electrode double-dielectric barrier discharge (DielectricBarrierDischarge, be called for shortDDBD), prior art exist complex structure, processing speed slow, consume large problem.
