Description

Technical Field

[0001] The utility model belongs to the field of ozone generating devices, and particularly relates to an ozone device using a micro-gap discharge technology. Background Art

[0002] Ozone molecules have strong oxidizing properties and can effectively kill microorganisms such as bacteria, viruses, and molds. Therefore, they are widely used in many fields such as drinking water treatment, sewage treatment, industrial oxidation, food processing and preservation, pharmaceutical synthesis, and space sterilization. Since ozone is easily decomposed and cannot be stored, it needs to be produced and used on-site through an ozone generating device.

[0003] Currently, in existing ozone generating devices, the generated oxygen needs to be injected between a dielectric glass tube and a titanium alloy stainless steel inner electrode. Due to different required ozone amounts, the oxygen content injected is different, but the cavity volume does not change, resulting in an affected oxygen flow rate and a decrease in ozone generation efficiency.

[0004] Therefore, in view of the problem that the cavity volume and length for injecting oxygen in the above-mentioned existing devices are fixed and cannot be adjusted according to different required ozone amounts, resulting in a decrease in ozone generation efficiency when the generated ozone amount is small, an ozone device using a micro-gap discharge technology is designed. The movable plate drives the oxygen delivery pipe inserted on it to move, changing the cavity volume to facilitate ozone generation. Summary of the Utility Model

By installing a sliding table 13 connected to the corrugated oxygen injection tube in the existing ozone generating device, the driving component provides power for the movement of the sliding table 13, so that the sliding table 13 moves back and forth in the outer shell 1. The sliding table 13 changes the volume of the cavity, enabling oxygen to fill the remaining cavity more quickly and be converted into ozone through discharge, improving the ozone generation efficiency. The cooling component can take away the high temperature generated by the discharge, and the lifting component can change the height of the ozone device.

[0027] Please refer to Figures 3-5, in this embodiment, the driving component includes a first threaded rod 701 and a first limiting column 702; the first threaded rod 701 is inserted into the outer shell 1, the first limiting column 702 is fixedly connected inside the outer shell 1, a threaded hole matching the first threaded rod 701 is formed on the sliding table 13, the sliding table 13 is sleeved outside the first limiting column 702, and the driving component further includes a first motor 703; the first motor 703 is installed on the outer shell 1, and the transmission element of the first motor 703 is connected to the first threaded rod 701.

After the first threaded rod 701 rotates, under the limitation of the first limiting column 702, the sliding table 13 screwed onto the first threaded rod 701 cannot rotate with the first threaded rod 701 but moves along the first limiting column 702. The first motor 703 provides power for the rotation of the first threaded rod 701 to change the position of the sliding table 13. The sliding table 13 closely adheres to the inner electrode 3, and together with the dielectric glass tube 4, the original cavity can be partitioned into two sections to change the volume of the cavity for oxygen flow.

[0028] Please refer to Figure 2 , Figure 6, in this embodiment, the cooling component includes a cooling water tank 1101 and a condensing pipe 1102; a cooling water tank 1101 filled with cooling water inside is installed on the outer shell 1, and a condensing pipe 1102 with both ends respectively inserted into the two ends of the titanium alloy stainless steel pipe 2 is connected inside the cooling water tank 1101. A support base 1201 and a support frame 1202 are fixedly connected to the bottom end of the outer shell 1; a support base 1201 is arranged below the outer shell 1, and a support frame 1202 fixedly connected to the outside of the outer shell 1 is arranged on the support base 1201. The lifting component includes a second threaded rod 1203, a second limiting column 1204, and a second motor 1205; a second threaded rod 1203 is arranged on the support base 1201, a second limiting column 1204 is fixedly connected to the support base 1201, a threaded hole matching the second threaded rod 1203 is opened on the support frame 1202, and a second motor 1205 with a transmission element connected to the bottom end of the second threaded rod 1203 is installed on the support base 1201. The cooling water is injected into the condensing pipe 1102 through the cooling water tank 1101, and then fills into the titanium alloy stainless steel pipe 2 along the condensing pipe 1102 to dissipate heat from the inner electrode 3. The aluminum alloy heat sink 6 connected to the outer electrode 5 can help dissipate heat from the outer electrode 5 to prevent the ozone device from overheating. The height of the ozone device is changed by moving the support frame 1202 on the support base 1201, so that ozone larger than air can be smoothly injected into the reaction tank.

[0030] The oxygen generated by the oxygen generator is injected into the cavity through the oxygen injection pipe. Using the micro-gap discharge technology, during the discharge process, the rapidly changing high voltage forms an electric dark current through oxygen. During this process, oxygen molecules are ionized, generating cations and free oxygen atoms. The cations react on the surface of the electrode, losing electrons and converting into oxygen, while the free oxygen atoms combine with another oxygen molecule to generate ozone. The cooling water tank 1101 injects the cooling water into the titanium alloy stainless steel pipe 2 through the condensing pipe 1102 to take away the heat generated by the inner electrode 3, and the aluminum alloy heat sink 6 takes away the heat generated by the outer electrode 5 to achieve heat dissipation.

[0031] Through the above steps, a sliding table 13 connected to the corrugated oxygen injection pipe is installed in the existing ozone generating device, and the driving component provides power for the movement of the sliding table 13, enabling the sliding table 13 to move back and forth within the outer shell 1. During the movement, the oxygen injection pipe is driven to move forward. The corrugated pipe has good stretchability. By changing the volume of the cavity through the sliding table 13, oxygen can fill the remaining cavity more quickly and be converted into ozone through discharge, improving the ozone generation efficiency, so as to solve the problem that the existing ozone device cannot change the volume of the cavity for oxygen injection according to different required ozone amounts, resulting in a decrease in the ozone generation efficiency.

[0032] The above has described the embodiments of the present utility model in detail with reference to the accompanying drawings.
