Description

Two water-cooling ozone discharge chambers

Technical field

The utility model relates to the ozone generating-device field, refers in particular to a kind of two water-cooling ozone discharge chambers of dielectric barrier discharge (DBD) and ozonizer of forming with this discharge chamber specialized in.

Background technology

Ozone has broad-spectrum bactericidal capacity, its disinfection efficiency height, remove look, deodorize is fast and non-secondary pollution, fields such as water treatment, sewage disposal, the recovery of middle water and sterilization in waterworks are widely used, but ozone can not be stored and transport, can only be in the situ production of using, so ozone generating-device has become the visual plant of above-mentioned industry.

Dielectric barrier discharge (DBD) is unique method of current scale operation ozone.The ozone discharge chamber is the ozoniferous key of dielectric barrier discharge, it is made up of ground electrode water cavity, high-voltage water cavity, generating pipe and air cavity, shell is as an electrode (outer electrode), discharge tube is the steel pipe that enamel material is warded off in the outside, the steel pipe of discharge tube forms another electrode (interior electrode), and its enamel layer is exactly a dielectric barrier.After applying ac high voltage between two electrodes, (generally be with outer electrode ground connection, claim ground electrode; Interior electrode connects high voltage electric, is called high voltage electrode), produce dielectric barrier discharge in the air gap and generate ozone, and the generating pipe temperature is risen.Along with raise its ozone output of the temperature of ozone generating pipe sharply descends, so the cooling of generating pipe is most important to improving ozone output and efficient.

Mostly discharge chamber only cools off ground electrode, but theory and practice all shows, it is better that the discharge chamber high voltage electrode is carried out cooling performance.Because ground electrode and high voltage electrode have very high potential difference, two electrodes are directly cooled off with same undressed water source (for example water-supply systems provide tap water) bigger difficulty: will conduct electricity by water between high voltage electrode and the ground electrode, side by side electrode (being the discharge chamber shell) also will be with high-voltage, and this will threaten to miscellaneous equipment and personnel safety.The utility model utilizes deionized water that the ground electrode and the high voltage electrode of discharge chamber are cooled off.
