Dielectric barrier discharge ozone generator using aluminum granules electrodes

• Industrial ozone generator with 35 parallel tubular electrodes attached in the same enclosure was described.
• Aluminum granules with sharp edges were filled in all 35 parallel tubular electrodes.
• Aluminum granules electrodes were used in this novel ozone generator to improve the efficiency of ozone generation.
• All 35 parallel tubular electrodes was cooled by cooling water.
• Effects of cooling water temperature and oxygen flow rate were studied.

An industrial ozone generator with 35 parallel tubular electrodes attached in the same enclosure was developed. Each tubular electrode consists of a stainless steel tube behaves as a ground electrode. A borosilicate glass tube was used as a dielectric material. The aluminum granules with sharp edges were filled in all the glass tubes. The aluminum granules in all 35 tubes were connected in parallel to the HV electrode. The outer surface of the stainless steel tubes was cooled by water. The aluminum granules electrodes were used in this novel ozone generator to improve the efficiency of ozone generation.
