The high-pressure nano-unit includes a stainless steel pressure tank 301, a porous ceramic plate 302, and a mechanical oscillator 303, wherein: Both the porous ceramic plate 302 and the mechanical vibrator 303 are placed inside the stainless steel pressure tank 301.

[0048] The robotic arm is also equipped with a laser rangefinder, which is used to collect the liquid level 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, including the following steps: The raw water undergoes multi-stage purification, and the purified raw water is then pre-treated with dissolved oxygen to obtain a high-oxygen solution. Electrolysis of the high-oxygen liquid yields high-oxygen, hydrogen-rich water. High-oxygen hydrogen-rich water is nano-sized to obtain homogeneous high-oxygen 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, including the following steps: Raw water first passes through activated carbon filter 101, which preferentially adsorbs residual chlorine and organic matter (removal rate ≥99.9%, COD ≤0.5mg / L), then through nano-silver filter 102, which removes heavy metals such as lead and cadmium (≥99.5%), and then through ultraviolet light 103, which completes microbial inactivation (≥99.99%). Finally, it passes through 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, so that the dissolved oxygen is ≥50 mg / L.

[0051] The online monitoring instrument 106 ensures TDS ≤ 5 ppm and conductivity ≤ 10 μS / cm, while the COD analysis module maintains organic matter ≤ 0.5 mg / L. The plate heat exchanger 105, combined with PID temperature control, achieves precise cooling of the raw water at 4 ± 1℃ (± 0.5℃). Ultimately, the water quality comprehensively exceeds the GB 17323-1998 standard, with key indicators being: residual chlorine / heavy metal removal rate ≥ 99.9% / 99.5%, COD ≤ 0.5 mg / L, TDS ≤ 5 ppm, dissolved oxygen ≥ 50 mg / L, and residual nitrogen ≤ 0.5 mg / L.

[0052] High-purity oxygen of 99.5% is injected into the mixing tank at a pressure of ≥0.6MPa through a Venturi jet injector. This high-pressure oxygen is then dispersed a second time through a 10μm titanium alloy sintered plate to form 15μm micron-sized bubbles before being sent into the mixing tank. It is then mixed with the raw water in the mixing tank, which has undergone three-stage series purification treatment, to form a pressurized water body. The oxygen saturation of this pressurized water body reaches 120% (controlled by Henry's Law). The pressurized water is then introduced into a negative pressure tank with a pressure of -95 kPa (staying time ≤ 8 seconds). Using Dalton's law of partial pressure, nitrogen is precipitated to obtain a high-oxygen liquid. The precipitated nitrogen is discharged from the gas outlet through an 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 number of cycles (2–3 times), nitrogen residue can be reduced to <0.5 mg / L after two cycles, providing a pure medium for subsequent processes. This process breaks the nitrogen dissolution equilibrium through supersaturated oxygen, combined with PID temperature control (±0.5℃) to suppress bubble aggregation, resulting in a replacement efficiency 5 times higher than traditional methods (time <3 minutes), while energy consumption accounts for only 12% of the total system power consumption.

[0054] The high-oxygen solution enters the proton exchange membrane electrolyzer, and is subjected to a voltage of 5.0V±0.5V and an A / cm² voltage of 300±50mA. ２ At the current density, electrolysis is performed for 10±2 minutes. The speed of the guide vane is controlled by a servo motor at 150±20 rpm, and the working pressure is maintained at 0.15-0.25 MPa to ensure that the gas retention time is ≥90 seconds. This causes the high-oxygen liquid in the reaction tank to generate a swirling gas flow, and the bubble diameter of the swirling gas flow is stabilized at 50-80 μm. At the same time, under the action of the eddy current generator, the swirling gas flow generates small eddies, which fully mix the newly generated hydrogen gas with water to obtain dissolved hydrogen gas, and finally obtain high-oxygen hydrogen-rich water.

[0055] After the high-oxygen hydrogen-rich water enters the stainless steel pressure tank 301, it penetrates the porous ceramic plate 302 and is subjected to ultrasonic vibration by the mechanical vibrator 303, causing the particles in the high-oxygen hydrogen-rich water to be nano-sized, resulting in a homogeneous fluid with a particle size ≤100nm.

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