Abstract

A Pin-Cylinder discharge type ozonizer was designed and manufactured. The increase or decrease of temperature greatly influences on the characteristics of ozone generation of a discharge type ozonizer. The characteristics of ozone concentration ( $O_{3con}$), ozone generation ($_{3g}$) and ozone yield .ate ($_{3Y}$) of the ozonizer were investigated by varying the gas flow rate (Q), the discharge power ($_{Wd}$ ) and the temperature (T). At T = 20($^{\circ}C$), the values of ( $O_{3con}$) were found as 7800,5300,3000 and 2300(ppm) at Q=1,2,4 and 6(1/min) respectively. The corresponding values of ( $O_{3g}$) were found as 917, l247,1411 and 1623(mg/h) and those of ( $O_{3Y}$) were 93,126,143 and 164(g/kWh) respectively. When the temperature is decreased to -50($^{\circ}C$), the values of ( $O_{3con}$) became 12000,8000,5200 and 3600(ppm) at Q=1,2,4 and 6(1/min) respectively. The corresponding values of 0,9 were obtained as 1411,1882,2446 and 2600(mg/h) and those of ($O_{3Y}$) were 143,190,247 and 2631g/kWh] respectively. Hence as the temperature was decreased from 20 to -50[。C], the efficiencies of ozone generation were increased by 54,51,73 and 60[%] at Q=1,2,4 and 6(1/min) respectively.ctively.
