Development of a Plasma-Dump Combustor for VOCs Destruction

Abstract

Volatile Organic Compounds are mainly produced by painting or during the painting drying processes, because of their low calorific value stable incineration of VOCs cannot be ensured with direct combustion, in this study, plasma dump is proposed for the removal of toluene, one of the most representative VOC compounds, by the application of adsorption and concentration, the plasma dump is combined with a 3 phase gliding arc plasma in a dump shaped form. in this study, the VOCs were stably removed by a combustion in the dump burner that can be used for mass treatment. besides, in order to achieve a complete combustion of the low calorific value VOCs, the interior of the reactor is newly designed for the outlet of the 3D matrix regenerator. To examine the VOc removal processing efficiency by the plasma dump reactor, the raw gas flux , the VOC concentration, the inlet position, and the effect of the installation of the 3D matrix, were investigated. at a toluene supply rate of 3000 ppm, an injection rate of 450 L/min, an input power of 2.5 ㎾, and in the case of the VOC inlet position on the exterior and the presence of the 3D matrix, the conditions resulted in an energy conversion rate of 12.27 ㎏ (㎾h)SUP-1/SUP.
