The utility model relates to the technical field of
hydrogen production by electrolyzing water, and discloses an alkaline
hydrogen production device by electrolyzing water, which comprises a base, an electrolytic tank is fixedly connected to the top of the base close to the front side, a power supply is fixedly connected to the front side of the electrolytic tank, and an alkaline liquid box is fixedly connected to the top of the base close to the right side. A
water cooling chamber is fixedly connected to the rear side of the top of the base, a
water storage tank is fixedly connected to the center of the top of the base, and an
air pump is arranged on the rear side of the base. In the water
electrolysis hydrogen production device, the pH
detector is arranged in the
electrolysis tank to monitor the acid-base property of the
electrolyte in real time, the pipeline for conveying the alkaline liquid is arranged at the top of the tank body, the acid-base state of the
electrolyte can be automatically adjusted according to the change of the pH value, and the collected hydrogen is conveyed to the
water cooling chamber, so that the
hydrogen production efficiency is improved. And the temperature of hydrogen generated by
electrolysis can be effectively reduced, and subsequent collection and treatment are facilitated.
