Described plasma purifier is flat-plate reactor or drum type brake reactor.
The discharge mode that described plasma adopts is the dielectric barrier discharge under the high-frequency and high-voltage power supply effect, corona discharge pulse or direct current glow discharge, and frequency range is 1-20kHz, and voltage range is 10-200kV.
Compared with prior art, the invention has the advantages that: because the exhaust gas inlet that is provided with on the housing of Tower for purifying waste gas is in the activated carbon adsorption bed below, plasma purifier is in the activated carbon adsorption bed top, activated carbon adsorption bed is provided with packing layer, be provided with electric heating tube in the packing layer, inside is provided with the temperature element that links to each other with outside temperature controller, when organic exhaust gas concentration is very high, active carbon can be adsorbed with organic pollutants, reduce the load impact of high concentration article on plasma body clarifier, and when low concentration or contamination-free, can temperature slowly be risen, desorption process takes place in the activated-charcoal column, discharge adsorbed organic pollution, thereby reduce the fluctuation of organic exhaust gas concentration, realize the stable operation of plasma purifier, significantly improve the treatment effect of plasma for purification, the potential safety hazard that reduction may exist is therefore applicable to handling big air quantity, low concentration, unsettled organic exhaust gas, and treatment process is simple, the purification efficiency height;
Because air inlet pipeline is provided with MOD and filter, organic exhaust gas is removed particle through filter, can avoid particle that Tower for purifying waste gas is caused damage, and when activated carbon adsorption bed is in detachment status, close MOD and can prevent that extraneous air-flow from entering housing, influence the desorption and regeneration effect of active carbon; Because Tower for purifying waste gas comprises the desorption blower fan, can make activated carbon adsorption bed organic exhaust gas that discharges and the air that provides by the desorption blower fan mix the concentration that reduces organic exhaust gas, more help follow-up plasma for purification and handle;
The present invention has avoided in traditional active carbon absorption technology that the active carbon amount of fill is big, saturated activity charcoal desorption and regeneration needs problems such as a series of auxiliary equipment, has that the active carbon amount of fill is little, the regenerative process simple operation and other advantages.
