Description

Technical Field

[0001] This utility model relates to the field of ozone preparation, and in particular to a rapid maintenance and testing device for the enamel discharge tube of a vertical medium-sized ozone generator. Background Technology

[0002] When an ozone generator is in operation, especially when using compressed air, even if the compressed air is precisely filtered, residual dust particles and water vapor in the filtered compressed air accumulate and form scale on the surface of the enamel ozone discharge tube during long-term operation. In addition, when the dust particles and water vapor accumulated in the compressed air flowing in the discharge gap channel exceed the standard, the insulation of the enamel dielectric layer sintered on the outside of the enamel discharge tube decreases and is broken down by high voltage. As a result, the enamel discharge tube is damaged and cannot operate normally to generate ozone through corona discharge.

[0003] If the enamel dielectric layer on the outer coating of the enamel discharge tube breaks down, the operating current that was originally evenly distributed among all the enamel discharge tubes in the ozone generator will be concentrated on the damaged enamel discharge tube. Furthermore, the current will discharge from the point of breakdown in the damaged enamel discharge tube to the stainless steel external electrode tube (zero-potential grounding electrode). All the high-voltage current will be released to the zero-potential grounding electrode, causing all the enamel discharge tubes in the entire ozone generator to stop discharging and operate. Normally, enamel discharge tubes produce a blue halo when discharging. However, once an enamel discharge tube breaks down, all the enamel discharge tubes in the ozone generator will stop discharging and will not produce a blue halo, including intact and normal enamel discharge tubes. The shutdown of the ozone generator will cause significant losses to the production company.

[0004] Previously, maintenance of ozone generators involved disconnecting all external gas and water flanges after the ozone generator was shut down and powered off, along with all signal lines on the gas and water pipes. Several people would then coordinate to lay the ozone generator on a horizontal position, extract and inspect all the enamel discharge tubes inside, identify and replace any damaged tubes, and then reassemble the generator. This method was time-consuming, labor-intensive, and time-consuming (approximately 1-2 days, longer for larger equipment), requiring several people to work together. Furthermore, the long downtime resulted in significant losses for the manufacturing company. Therefore, it is necessary to propose a rapid maintenance and testing device for the enamel discharge tubes of vertical medium-sized ozone generators to solve these problems. Utility Model Content

The insulating tape 31 is installed on the outside of the enamel discharge tube to separate it from the stainless steel external electrode tube 32, that is, the insulating tape 31 separates the enamel discharge tube from the stainless steel external electrode tube. The stainless steel external electrode tube 32 is isolated to form a discharge gap channel 34 for corona discharge between the high voltage electrode and the low voltage electrode to generate ozone. The stainless steel external electrode tube 32 is welded to the two end holes of the stainless steel perforated plate 45 inside the ozone generator cylinder 4.

[0026] Furthermore, the high-voltage detection device 2 includes a high-voltage fuse and a high-voltage electrode connecting piece 21. The high-voltage fuse is cylindrical in shape, with an upper external thread 22 at the upper end and a lower external thread 28 at the lower end. A ceramic cylinder 23 is located in the middle of the high-voltage fuse, and the interior of the ceramic cylinder 23 is filled with quartz sand 24. A silver-copper connecting wire 29 is installed in the middle of the quartz sand 24, and the silver-copper connecting wire 29 is fixedly connected to the upper external thread 22 and the lower external thread 28 for electrical conductivity. The top of the enamel discharge tube is provided with a top internal thread 25 and a top external thread 26. An insulating epoxy support strip 210 is installed on the outer ring of the part. The insulating epoxy support strip 210 is fixed to the top of the enamel discharge tube by a fixing nut 27. The fixing nut 27 is threadedly connected to the top external thread 26.

The lower external thread 28 of the high voltage fuse is screwed into the interior of the top internal thread 25. The upper external thread 22 of the high voltage fuse is fastened to the high voltage electrode connecting piece 21. The high voltage electrode connecting piece 21 is connected to the high voltage electrode device 1 of the ozone generator to obtain high voltage, and provides high voltage corona discharge to the enamel discharge tube to generate ozone.

[0027] This utility model addresses the problems of existing technologies that require time-consuming and labor-intensive inspection and maintenance of enamel discharge tubes, necessitating multiple people to work together and resulting in significant downtime and losses for manufacturers. It adds a high-voltage detection device 2 to the top of the enamel discharge tube. Through a high-voltage fuse, damaged enamel discharge tubes can be quickly and effectively located, and the damaged tube can be quickly removed and replaced with a new one. The entire repair process takes approximately 30 minutes: locating the damaged tube takes about 5 minutes, replacing and installing the new tube takes about 10 minutes, and the entire repair is completed in about 30 minutes.

[0028] The specific measures are as follows: When the ozone generator is powered off, open the top cover plate 41 of the ozone generator cylinder 4, without disconnecting the gas and water pipe flanges or disconnecting the signal lines. The ozone generator cylinder 4 can be moved out and leveled without the need for several people. Then, power on the ozone generator electrical cabinet and adjust all gas and water flow and pressure values ​​of the ozone generator to zero on the ozone electrical cabinet touch screen screen. Adjust them to the lower limit of the alarm value so that no alarm occurs. Close all manual valves of the ozone generator's inlet and outlet. Then, turn on the enamel discharge tube and run it for 3-5 minutes. If the enamel discharge tube does not produce a blue halo after running for 3-5 minutes, immediately turn off the ozone generator and disconnect the power. Then, touch the outer cylindrical ceramic of the high-voltage fuse. If the ceramic cylinder 23 is hot, the enamel discharge tube connected to it below is definitely damaged by a breakdown. The other cylindrical ceramic cylinders 23 are at normal temperature, and the enamel discharge tubes connected to them are normal and undamaged.

[0029] Disconnect the stainless steel high-voltage connecting piece 33, and quickly pull out the damaged enamel discharge tube using a special pry bar tool. Replace it with a new one and reinstall it. The detection principle is as follows: After the enamel dielectric layer on the outer coating of the enamel discharge tube is punctured, the operating current that was originally evenly distributed to each enamel discharge tube in the ozone generator is all concentrated on the damaged enamel discharge tube. It then flows from the high-voltage detection device 2 to the point where the enamel discharge tube is punctured, discharging current to the stainless steel external electrode tube 32. All the high-voltage current is released to the zero-potential grounding terminal. Like water flow, the high-voltage current flows from the side with the lowest resistance. After the enamel dielectric layer on the outer coating of the enamel discharge tube is punctured, the enamel is missing... The ceramic dielectric barrier layer is essentially gone, meaning the enamel insulation layer is missing. The resistance of the high-voltage current path is relatively low here, and the high-voltage current is entirely released to the zero-potential grounding terminal of the stainless steel external electrode tube 32. Meanwhile, the silver-copper connecting wire 29 inside the ceramic body 23 of the high-voltage fuse has resistance. The high-voltage current flowing through the silver-copper connecting wire 29 generates heat. When the damaged enamel discharge tube is connected to high voltage for 3-5 minutes, the heat generated by the silver-copper connecting wire 29 increases over time. This heat is conducted to the outer shell of the ceramic body 23, causing the outer shell temperature to be significantly higher than normal, which can be sensed by touch. This allows for quick identification of the damaged enamel ozone discharge tube.

[0030] The ceramic cylinder 23 is filled with quartz sand 24, which is mainly used to extinguish arc light and prevent leakage at the contact point between the lower external thread 28 of the high-voltage fuse and the upper internal thread 25 of the enamel discharge tube caused by the generation of surface discharge arc light. The silver-copper connecting wire 29 has better high-voltage conductivity than pure copper wire.

[0031] The above-mentioned components are combined to form a rapid maintenance and testing device for the enamel discharge tube of a vertical medium-sized ozone generator. The device offers several advantages: it is made of common materials, resulting in low cost and minimal usage; the components are easy to manufacture and readily available in the market; installation is convenient; and the high-voltage testing device 2 enables rapid and efficient maintenance of the ozone generator, saving time and effort, reducing maintenance time and workload, requiring only one person to operate, and lowering installation and maintenance costs. It can quickly restore the ozone equipment to normal operation, increasing production, reducing expenses, and generating revenue for enterprises.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
