[0039] Example 5 Based on Example 1, this example provides a high-oxygen, hydrogen-rich water preparation system based on PEM electrolysis-nanoceramic plate coupling, wherein the high-pressure nanostructured unit includes a stainless steel pressure tank 301, a porous ceramic plate 302, and a mechanical oscillator 303, wherein: The porous ceramic plate 302 and the mechanical oscillator 303 are both placed in a stainless steel pressure tank 301 .

[0043] The fluid outlet is communicated with a nitrogen protection filling head.

[0044] The working process of this embodiment: The high-oxygen, hydrogen-rich water output by the PEM electrolysis-gas mixing cabin unit passes through the porous ceramic plate 302 and enters the stainless steel pressure tank 301, where it is nano-processed under the action of the mechanical oscillator 303, ultimately obtaining a homogeneous fluid with a particle size of ≤100 nm.

[0045] Example 6 Based on Example 1, this example provides a high-oxygen, hydrogen-rich water preparation system based on PEM electrolysis-nanoceramic plate coupling, wherein the nitrogen-protected filling head includes a robotic arm 402, on which a filling nozzle 401 is mounted, and the inlet of the filling nozzle is connected to the outlet of the high-voltage nano-unit.

[0046] A 0.1 μm hydrophobic filter membrane is provided at the water outlet of the filling nozzle 401 .

[0047] The robot arm is further provided with a nitrogen output component, the nitrogen outlet of which is located on one side of the filling nozzle 401 , so as to form a nitrogen curtain at the filling nozzle 401 .

[0048] The robotic arm is also provided with a laser rangefinder, which is used to collect the liquid level height in the filling bottle and transmit it to the intelligent control system.

[0049] Example 7 This embodiment provides a method for preparing high-oxygen hydrogen-rich water based on PEM electrolysis-nano-ceramic plate coupling, comprising the following steps: The raw water is purified in multiple stages and the purified raw water is pretreated with dissolved oxygen to obtain high-oxygen liquid; Electrolyze the high-oxygen liquid to obtain high-oxygen hydrogen-rich water; The high-oxygen and hydrogen-rich water is nano-processed to obtain homogeneous high-oxygen and hydrogen-rich water.

[0050] Example 8 This embodiment provides a method for preparing high-oxygen hydrogen-rich water based on PEM electrolysis-nano-ceramic plate coupling, comprising the following steps: The raw water passes through the activated carbon filter 101 to preferentially adsorb residual chlorine and organic matter (removal rate ≥99.9%, COD ≤0.5mg / L), passes through the nano-silver filter 102 to intercept heavy metals such as lead and cadmium (≥99.5%), and is inactivated by ultraviolet light 103 to complete microbial inactivation (≥99.99%). It then passes through the 0.22μm microfiltration membrane 107 for terminal filtration before entering the mixing tank. The oxygen injection system 104 delivers oxygen to the mixing tank at a flow rate of 30-50 L / min to replace nitrogen and make the dissolved oxygen ≥50 mg / L.

[0051] Online monitoring instrument 106 ensures TDS ≤ 5ppm and conductivity ≤ 10μS / cm. A COD analysis module maintains organic matter ≤ 0.5mg / L. Plate heat exchanger 105, combined with PID temperature control, achieves precise cooling of the raw water to 4±1°C (±0.5°C). The resulting water quality surpasses the GB 17323-1998 standard. Key indicators include: residual chlorine / heavy metal removal rates ≥ 99.9% / 99.5%, COD ≤ 0.5mg / L, TDS ≤ 5ppm, dissolved oxygen ≥ 50mg / L, and residual nitrogen ≤ 0.5mg / L.

[0052] 99.5% high-purity oxygen is injected into the mixing tank at a pressure of ≥0.6MPa through a Venturi ejector. The high-pressure oxygen is secondary dispersed by a 10μm titanium alloy sintered plate to form 15μm micron-sized bubbles, which are then sent to the mixing tank and mixed with the raw water in the mixing tank that has undergone three-stage series purification treatment to form a pressurized water body with an oxygen saturation of 120% (controlled by Henry's law); The pressurized water is then introduced into a negative pressure tank with a pressure of -95kPa (retention ≤8 seconds), and Dalton's law of partial pressure is used to promote the precipitation of nitrogen to obtain a high-oxygen liquid. The precipitated nitrogen is discharged from the gas outlet through the O2 / N2 membrane separator, and the precipitated residual oxygen is connected to the oxygen inlet of the mixing tank through the exhaust port.

[0053] Finally, by dynamically adjusting the oxygen pressure (0.6-0.8 MPa), negative pressure intensity (-90-95 kPa), and the number of cycles (2-3), residual nitrogen can be reduced to less than 0.5 mg / L after two cycles, providing a pure medium for subsequent processes. This process uses supersaturated oxygen to break the nitrogen dissolution equilibrium, combined with PID temperature control (±0.5°C) to suppress bubble coalescence. This method increases replacement efficiency fivefold compared to traditional methods (taking less than 3 minutes), while consuming only 12% of the system's total power consumption.

[0054] The high oxygen liquid enters the proton exchange membrane electrolyzer and is charged at a voltage of 5.0V±0.5V and a current of 300±50mA / cm 2 Under the current density, electrolysis is carried out for 10±2 minutes, and the guide vane speed is controlled by the servo motor at 150±20rpm, maintaining a working pressure of 0.15-0.25MPa, ensuring that the gas retention is ≥90 seconds, so that the high-oxygen liquid in the reaction tank generates a rotary shear airflow, and the bubble diameter of the rotary shear airflow is stabilized at 50-80μm; at the same time, under the action of the vortex generator, the rotary shear airflow generates small vortices, so that the newly generated hydrogen is fully mixed with water to obtain dissolved hydrogen, and finally obtain high-oxygen hydrogen-rich water.

[0055] After entering the stainless steel pressure tank 301, the high-oxygen, hydrogen-rich water penetrates the porous ceramic plate 302 and is subjected to ultrasonic vibrations from the mechanical oscillator 303. This nano-scales the particles in the high-oxygen, hydrogen-rich water, resulting in a homogeneous fluid with a particle size of ≤100nm. This significantly enhances the stability of the dissolved gas, effectively suppressing the escape of hydrogen and oxygen, and extending the shelf life of the activated water.

[0056] The homogeneous fluid was filled into the filling bottles through a nitrogen-protected filling head at a speed of 0.5 seconds per bottle.
