Description

Technical Field

[0001] The utility model relates to a tubular ozone generator, belonging to the technical field of ozone generators. Background Art

[0002] As a new type of strong oxidizing substance generating device, ozone generator is widely used in related industries such as disinfection and sterilization, food processing and preservation, application synthesis, water treatment, air pollution control, odor treatment, etc. Ozone molecules have extremely high electrode potential, that is, they have strong oxidizing properties, which can oxidize and denature various bacteria, viruses and pollutants, thereby achieving the purpose of sterilization and removal of pollutants. Moreover, ozone will generate oxygen after reaction. Compared with chlorine and other similar products, there is no secondary pollution, and it is an environmentally friendly strong oxidant.

[0003] The tubular ozone generator in the prior art includes an enameled tube and a steel tube located outside the enameled tube. There is a gap between the inner wall of the steel tube and the outside of the enameled tube. The gap is connected to an air inlet and an exhaust port. The enameled tube and the steel tube are respectively connected to a positive electrode and a negative electrode. Oxygen is introduced from the air inlet, and is ionized to produce ozone when passing through the first gap. Finally, the ozone is discharged from the exhaust port.

[0004] The tubular ozone generator in the prior art has the following disadvantages:

[0005] 1. The surface cylindricity of the outer wall of the internal enamel tube is poor, which leads to the inconsistency of the discharge gap between the enamel tube and the external steel tube, thus affecting the generation of ozone;

[0006] 2. Due to the inconsistency of the discharge gap, it is impossible to maintain a small discharge gap as a whole. The only way is to increase the discharge gap to prevent high-voltage breakdown at the location with a small discharge gap;

[0007] 3. The positive pole of the external power supply is connected to a certain point of the enameled tube, the electricity is unevenly distributed on the enameled tube, and the discharge effect is poor.

[0008] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
