The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The invention provides a hydrogen-oxygen self-balancing device of a water electrolysis hydrogen production system, which is explained in detail with reference to fig. 1 to 2.
An electrolytic water hydrogen production system hydrogen and oxygen self-balancing device, comprising: the hydrogen-oxygen separator comprises a hydrogen separator 1 and an oxygen separator 6, wherein a buffer tube 4 for balancing pressure is communicated between the hydrogen separator 1 and the oxygen separator 6, a hydrogen-side piston 3 is arranged at one end, close to the hydrogen separator 1, in the buffer tube 4, and an oxygen-side piston 5 is arranged at one side, close to the oxygen separator 6, in the buffer tube 4.
A pressure-relieving balance medium is filled in the buffer tube 4 between the hydrogen-side piston 3 and the oxygen-side piston 5, and in this embodiment, the pressure-relieving balance medium is a gas medium, specifically nitrogen, and in other embodiments, the pressure-relieving balance medium may also be a liquid medium. Meanwhile, in order to ensure that the pressure-relieving balance medium can work normally without affecting the hydrogen separator 1 and the oxygen separator 6, the volume in the buffer tube 4 is the sum of the volume of the hydrogen separator 1 and the volume of the oxygen separator 6, and the pressure of the pressure-relieving balance medium in the buffer tube 4 is 50% of the rated working pressure of the electrolytic cell where the self-balancing device is located.
Further, in order to prevent the hydrogen-side piston 3 and the oxygen-side piston 5 from being constantly placed in the buffer tube 4 during operation due to the pressure generated in the electrolytic cell by the hydrogen separator 1 and the oxygen separator 6, porous support members 2 are provided at both the positions where the hydrogen separator 1 communicates with the buffer tube 4 and the positions where the oxygen separator 6 communicates with the buffer tube 4. In this embodiment, the porous support member 2 is provided in a disc shape, and a plurality of circular through holes are provided in an array on the end surface of the porous support member 2 so as to penetrate the porous support member 2. In some embodiments, the circular through-holes provided on the porous support member 2 may be polygonal through-holes. The hydrogen gas in the hydrogen separator 1 and the oxygen gas in the oxygen separator 6 can enter the buffer tube 4 through the porous support member 2, thereby completing the pressure balance adjustment of both sides of the hydrogen separator 1 and the oxygen separator 6 in the buffer tube 4 in cooperation with the pressure-relieving balance medium, the hydrogen-side piston 3, and the oxygen-side piston 5. And to avoid leakage of hydrogen or oxygen gas generated in the electrolytic cell into the buffer tube 4, the porous support member 2 is sealingly connected to the buffer tube 4.
The invention also provides a hydrogen-oxygen self-balancing method of the water electrolysis hydrogen production system, which is used for implementing the hydrogen-oxygen self-balancing device of the water electrolysis hydrogen production system, and the method comprises the following steps with reference to fig. 3:
s1, packaging a pressure-relieving balance medium in advance in the buffer tube 4, wherein the pressure of the pressure-relieving balance medium is 50% of the rated working pressure of the electrolytic cell in which the self-balancing device is positioned, and assembling the hydrogen-oxygen balance device of the water electrolysis hydrogen production system;
s2, placing the assembled hydrogen-oxygen self-balancing device of the water electrolysis hydrogen production system in an electrolytic cell, respectively placing the hydrogen separator 1 and the oxygen separator 6 in the electrolytic cell at the corresponding hydrogen side and oxygen side, and starting the electrolytic cell to perform water electrolysis hydrogen production operation;
s3, in the hydrogen production operation by electrolyzing water, the hydrogen side piston 3 and the oxygen side piston 5 in the buffer tube 4 move in the buffer tube 4 according to the pressure of the hydrogen separator 1 and the oxygen separator 6 to adjust the pressure of the hydrogen separator 1 and the oxygen separator 6.
Specifically, the hydrogen-side piston 3 and the oxygen-side piston 5 have different operating states for different operating conditions, and in S3, when the pressure on both the hydrogen side and the oxygen side of the electrolyzer reaches 50% of the rated operating pressure of the electrolyzer, the positions of the hydrogen-side piston 3 and the oxygen-side piston 5 are not changed.
At S3, when the hydrogen and oxygen side pressures of the cell reach 100% of the cell' S rated operating pressure, the hydrogen-side piston 3 and the oxygen-side piston 5 both compress the buffer tube 4 toward the middle of the buffer tube 4 by a quarter of the total volume to reach a new equilibrium.
At S3, when the pressure suddenly rises on either of the hydrogen side and the oxygen side, the corresponding hydrogen side piston 3 or oxygen side piston 5 moves into the buffer tube 4, and the other oxygen side piston 5 or hydrogen side piston 3 moves toward the end of the buffer tube 4, so that the hydrogen side and the oxygen side of the electrolytic cell are again in equilibrium. In this embodiment, taking the case of 20% increase in hydrogen side pressure, assuming that the rated pressure of the electrolyzer is 1MPa, and the hydrogen side pressure of the electrolyzer suddenly increases from 1MPa to 1.2MPa, the hydrogen side piston 3 moves one fifth of the total volume of the buffer tube 4 toward the middle of the buffer tube 4 in a compression manner, and the oxygen side piston moves one tenth of the total volume of the buffer tube 4 toward the end of the buffer tube 4 in a compression manner, so as to achieve pressure balance again.
