Problems solved by technology

The current alkaline electrolyzed water hydrogen production equipment has the disadvantages of high energy consumption and low efficiency
[0003] The existing research on the role of magnets in hydrogen production is mainly based on magnetohydrodynamics. By placing magnets around the electrolyte, the Lorentz force generated affects the natural convection and mass transport of the electrolyte in the electrolyzer. However, this method is currently only Staying in the stage of small-scale electrolysis hydrogen production experiment, because the small-scale electrolysis experiment did not fully consider the complex working conditions in industrial hydrogen production and the structure and material permeability of the actual electrolysis equipment, resulting in this method not suitable for application in industrial electrolysis hydrogen production

Embodiment 1

[0027] Example 1 is as image 3 As shown, the magneto-level transition device 2 and the electrolytic cell 1 adopt a parallel structure, and the electrolytic cell 1 includes a plurality of electrolysis chambers, and each electrolysis chamber is respectively provided with a liquid inlet, and each liquid inlet is correspondingly connected with a magneto-energy Level transition device 2, the liquid inlets of all magneto-induced energy level transition devices 2 are communicated with the liquid outlet of the circulation device. The advantage of using the parallel structure is that, by using the parallel structure, each electrolysis cell will be connected to the electrolyte of the same active strength, and the attenuation will be less than that at the end of the treatment. At the same time, the parallel structure can reduce the energy consumption of electrolysis and reduce hydrogen production cost. The parallel structure is suitable for large-scale multi-chamber industrial electrol...

[0028] Example 2 is as Figure 4 As shown, the magneto-level transition device 2 and the electrolytic cell 1 adopt a series structure, a liquid inlet is opened at one end of the electrolytic cell 1 , and the magneto-level transition device 2 is communicated with the liquid inlet of the electrolytic cell 1 . The liquid inlet of the magnetic level transition device 2 is communicated with the liquid outlet of the circulation device, and the lye flowing out from the circulation device enters the electrolytic cell 1 after being magnetically treated by the magnetic level transition device 2 . The lye in the series structure enters from the first electrolysis chamber, undergoes an electrolysis reaction, and then enters the second electrolysis chamber. At this time, the activity of the lye attenuates, by Figure 9 It can be seen that the magneto-level transition device 2 of the series structure makes the electrolytic reaction activity of the electrolyte entering the electrolytic cell ...
