Each frequency converter 13 supplies power to two generator units 14 via two electrode aviation plugs 17. The touch screen 9 has a built-in historical parameter storage unit that can store and recall at least 20 sets of operating parameters. The generator unit module consists of six independent generator unit components 22 that are fixedly assembled via a lower valve plate 23 and an upper valve plate 24. The lower valve plate 23 has a through-type long air hole and a long water hole that are respectively connected to the ionization chamber and cooling water channel of each generator unit component 22.

[0037] The generating unit assembly 22 includes: a sealed housing composed of an outer left plate 28 and an outer right plate 29; a stacked oxide ceramic plate 30 and an electrode substrate 31 with embedded electrode plates; an ionization cavity is formed between the electrode substrate 31 and the oxide ceramic plate 30, a first cooling water channel is formed between the electrode substrate 31 and the outer left plate 28, and a second cooling water channel is formed between the electrode substrate 31 and the outer right plate 29; the dielectric constant of the oxide ceramic plate 30 is ≥3000, the thickness is 0.8±0.1mm, and the surface roughness Ra≤0.2μm; the electrode plates of the electrode substrate 31 are connected to the electrode aviation plug 17 via an aviation socket, and the connection point is provided with a self-locking anti-loosening structure; the magnetic water flow switch 25 is interlocked with the frequency converter 13, and automatically cuts off the power output when the cooling water flow rate is lower than 5L / min; the temperature sensor 27 is equipped with...

[0038] This device adopts a modular plate structure, combining high-frequency high-voltage discharge and intelligent control technology to achieve efficient and stable ozone generation. Oxygen input: External oxygen enters the system through oxygen inlet 20, and the flow rate is precisely controlled by pressure regulating valve 4 and oxygen flow meter 3. Subsequently, it is distributed to six parallel generating units 14 through oxygen inlet pipe 19. The oxygen enters the ionization chamber of the generating unit component 22, which is composed of electrode substrate 31 and oxide ceramic plate 30. Under the action of high-frequency high-voltage electric field, an ionization reaction occurs, and the generated ozone gas is collected through the elongated gas hole of upper valve plate 24 and output from ozone outlet 5 through ozone outlet pipe 18.

[0039] Cooling water circulation: External cooling water enters from the cooling water inlet 21, flows through the inlet pipe 15 into the long water hole of the lower valve plate 23, and is divided into the cooling water channels of the six sets of generating unit components 22. The first cooling water channel is located between the outer plate left 28 and the electrode substrate 31, directly cooling the electrode; the second cooling water channel is located between the outer plate right 29 and the oxide ceramic plate 30, preventing the ceramic plate from overheating; when the temperature sensor (27) detects overheating, it automatically reduces the power output to avoid equipment damage.

[0040] Temperature monitoring: Cooling water ultimately flows into the tee 26 through the elongated water hole of the upper valve plate 24. The water temperature is monitored in real time by the temperature sensor 27. If the water temperature exceeds the set threshold (e.g., 50℃), the system automatically reduces the frequency or shuts down for protection.

[0041] Water flow interlock: The magnetic water flow switch 25 detects the water flow status. If the flow rate is insufficient (<5L / min), the power supply is immediately cut off to prevent dry burning and damage to the electrodes. The ozone output, concentration and other parameters are set through the touch screen 9. The PLC controller 12 automatically calculates the optimal operating frequency. The frequency converter 13 controls three frequency converters 13 to drive six groups of generating units 14 respectively (each power supply controls two groups). High-frequency AC power is used to improve ozone generation efficiency. If a group of electrodes fails, the remaining units can still operate independently to ensure equipment reliability.

[0042] Emergency stop button 10 manually cuts off power in an emergency; buzzer alarm light 11 triggers audible and visual alarms when water is lacking, overheating, or power is abnormal; oxide ceramic plate 30 reduces carbon buildup during discharge; optimized cooling water channel design avoids local overheating that could lead to electrode aging.
