Abstract | An efficient grid type ozonizer have been fab1icated for laboratory scale appHc11tions requiring highly concentrated ozone. It consists of a stainless steel inner grid as high voltage discharge eJec1 rode, rnclius of which is very close 1.o the radius of outer glass rube, acHng as grounded electrode. The ourer glass tuhe is cooled directly with water from laboratory supply. Performance analysis of fabricated ozonizer wirh two types of discharge electrodes, each on e furnishing one mode of oxygen flow through reactor, was cariied out to asce1ta.in the maximum ozone concencration C (mg0 /t0~ and energy yield YO (g03 /kWh) attended. For first mode (wit.h oxygen flowing through discharge gap and hollow g1id electrode at volwne flow rate 4ml/s) an energy yield YO = 67 gO;/l(Wh and ozone concentration C = 70 mg0 3 /J0 2 was secured. For second mode (wjt}1 oxygen flowing only through discharge gap at volume flow rate 2.5ml/s) an energy yield YO = 48 g03 /kWh and ozone concentration 80 mg03 /J02 was secured. An expeiimental investigation was conducted to consolidar.e the concept pertaining to 1J1e generation of excited ozone. Experimental results 1malysis revealed that ozone genera ted. at high electric fi eld imensir.y (kV / mm) within discharge gap have differenr. attiibu1es b1 compa1ison lo ozone generated al low electric field intensity . .

Simple Unear mathematical models sbnulatb1g the process of ozone production and heat transfer from discharge gap r.o water fl ow circuit and oxygen flow circuit have been developed. |
