Pulsed corona spray

Figure 4-95. Schematics of (a) wet and (b) spray configurations of the pulsed corona discharges.

Figure 11-67. Comparison of the plasma-stimulated VOC removal effieieney using wet pulsed eorona and regular (dry) pulsed corona. DRE of methanol (initial eoneentration 1000 ppm) and acetone (initial concentration 200 ppm) are presented in both types of corona as function of SEE Water flow rates in the spray of the wet pulsed corona are 0.4 mL/min for methanol removal, and 1 mL/min for acetone removal.

Figure 11-68. Mobile Environmental Laboratory built in Drexel University carrying preeise exhaust gas eharaeterization faeility as well as 10 kW wet (spray) pulsed corona discharge for treatment of large-volume low-concentration exhaust gases containing VOCs.

A mobile plasma laboratory for VOC removal from the exhaust streams typical for paper mills and wood processing plants (see Table 11 ) has been built at Drexel University (Fig. 11-68, see Gutsol et al., 2005) based on 10 kW wet (spray) pulsed corona discharge. A photograph of the discharge from one of the six windows is presented in Fig. 11-69 all...
